Abstract: A method for pivotably adjusting a first portion of a device in two directions relative to a second portion of the device includes: rotating the first portion relative to the second portion, about a first pivoting axis of a biaxially pivotable hinge and a uniaxially pivotable hinge, to be in a closed position (or a first open position) whereby the uniaxially pivotable hinge automatically deepens engagement when opened about the first pivoting axis; and rotating the first portion relative to the second portion about a second pivoting axis of the biaxially pivotable hinge to be in the closed position (or a second open position) whereby urging of the first portion relative to the second portion causes automatic disengagement of the uniaxially pivotable hinge.

Abstract: A method 300 and device for visual compensation captures 330 an image using an imager, detects 360 whether eyeglasses are present in the image, and sets 363 an electronic visual display to a larger font size, if eyeglasses are not detected as present in the image. If eyeglasses are detected as present in the image, the electronic visual display is set 367 to a normal font size. The method and device can be triggered 320 (for example) by an incoming call or message, by a touch screen activation, a key press, or by a sensed motion of the device. The method can be repeated from time to time to detect whether a user has put on eyeglasses (or taken off eyeglasses) after the first image capture. The method and device compensates for users with presbyopia (and some other types of visual impairments) who intermittently wear glasses.

Abstract: A method for selecting an alternate wireless communication system for a wireless communication device is disclosed. The method comprises using a first radio access technology (RAT) by a wireless communication device when scanning (202) for an initial wireless communication network (201). The wireless communication device further registers (215) to the initial wireless communication network (201). Then, the initial wireless communication network (201) determines (206) alternate RAT wireless communication network information for the wireless communication device and sends (235) the alternate RAT wireless communication network information to the wireless communication device.

Abstract: A continuous redundancy check method and apparatus receives (110) at least one data bit of a block's payload, calculates (120) a partial redundancy check value using the at least one data bit, compares (130) the partial redundancy check value with a reference value, and stores (134, 138) in an index an indication of whether the calculated redundancy check value matched the reference value. Meanwhile, the at least one data bit is also stored (140) in a data memory. As additional data bits of the payload are received, cumulative partial redundancy check values are calculated and compared to the reference value. When the complete payload has been stored (140), the index is analyzed (160, 165) to determine if a block error has been detected by the redundancy check functions. This continuous redundancy check method and apparatus allows a receiver to quickly determine whether a block error has occurred, especially when there may be padding (or dummy) bits in the block's payload.

Abstract: A method for maintaining timing across discontinuous activity gaps for a non-real time data interface, in a radio frequency (RF) IC is disclosed. The method comprises starting a first receive mode in the RF IC to receive analog RF signals 210 in response to receiving a first command from a base band (BB) IC, converting the analog RF signals 215 into a first stream of digital data samples, and transmitting 225 the samples to the BB IC. Next, the RF IC stops the first receive mode 235 in response to receiving a second command from the BB IC and transmits 245 dummy data samples to the BB IC. Then the RF IC re-starts the first receive mode 275 in response to receiving a third command from the BB IC 270, converts analog RF signals received by the first receive mode into a second stream of digital data samples 285, and transmits the samples to the BB IC 298.

Abstract: A method to establish a full-duplex audio connection over an asynchronous Bluetooth link between an audio terminal and a wireless audio device exchanges supported service classes and codecs between the audio terminal and the wireless audio device, negotiates a service class and a codec that are common to the audio terminal and the wireless audio device, and establishes an asynchronous audio connection between the audio terminal and the wireless audio device using the common service class and the codec. The audio connection established can depend on the software application desiring the audio connection plus the available service classes and codecs at the audio terminal and wireless audio device. For non-internet protocol (non-IP) audio applications, an ACL using AVDTP may be selected; for IP audio applications, an ACL using BNEP may be selected. Both AVDTP and BNEP can use codecs that support wide bandwidth audio.

Abstract: A method for coexistence of an orthogonal frequency division multiple access (OFDMA) receiver (117) such as a WiMAX receiver with a synchronous frame-based transmitter (115) such as a Bluetooth transmitter within a mobile station (110) receives an estimated media access protocol (MAP?) signal indicating when a MAP message is expected to be received by the OFDMA receiver (117) and uses it at a Bluetooth shutdown signal (190) at least when a MAP message is expected to be received. The MAP? signal can be taken directly from the ODFMA transceiver (117) or it may be produced through analysis of a receiver-enable (RXE) signal that includes not only MAP symbols but also downlink data symbols. The RXE signal can be analyzed using interrupt-and-timer, Fast Fourier Transform, covariance, and/or delay-locked loop techniques to extract historical MAP symbol information and generate expected MAP symbol information.

Abstract: A method for detecting a GSM channel of interest, in a wireless communication device capable of supporting broadband as well as narrowband wireless systems, includes receiving (210) analog signals across a wide bandwidth and identifying (220) possible GSM channels within that wide bandwidth. The wireless communication device then samples (230) the analog signals to produce a time domain digital signal and further chooses (240) a pair of frequencies that correspond to a possible GSM channel. The wireless communication device converts (260) the time domain digital signal at the chosen pair of frequencies into first and second frequency domain digital signals and calculates (270) a power ratio between the first frequency domain digital signal and the second frequency domain digital signal. If the calculated power ratio for the possible GSM channel exceeds a threshold, the wireless communication device determines (280) that the possible GSM channel is the GSM channel of interest.

Abstract: A wireless base unit (102) supporting carrier aggregation determines a truncation time period (159, 169) in order to create a reduced subframe component (154, 164) on an additional component carrier (120) such that the truncated subframe component (154, 164) does not interfere with the control region (171, 172) of a subframe (170, 180) transmitted on an overlapping component carrier (130) by an uncoordinated second base unit (105). The wireless base unit (102) transmits the truncated subframe component (154, 164) and also transmits truncation time period information within a control region (151, 161) of an anchor carrier (110). A remote terminal (104, 108) that supports carrier aggregation searches a control region (151, 161) of a subframe (150, 160) transmitted on the anchor carrier (110) for truncation information and uses the truncation information to determine a boundary of a data region in a subframe component (154, 164) received on the additional component carrier (120).

Abstract: A method for facilitating a mobile station to perform a fast handoff in a wireless communication system allows a handoff procedure to be anticipated (by the mobile station, its serving base station, or both) based on historical information regarding prior successful handoff procedures. In operation, the mobile station receives a neighbor list from a serving base station and determines whether a member base station of the neighbor list is a successful target base station based on historical data. If the member base station is not a successful target base station, the mobile station scans the member base station, measures a signal quality associated with the member base station, and sends a measurement report for the member base station when the signal quality meets a standard signal quality threshold. If the member base station is a successful target base station, the mobile station sends the measurement report for the member base station when the measured signal quality meets a lower signal quality threshold.

Abstract: Portable devices (100) that include displays (102) and are used in widely ranging ambient light conditions use selectable or adjustable optoelectronic input/output compensation functions to drive their displays. According to certain embodiments, a camera (122) or a light sensor (120) is used to measure the ambient light level, and an optoelectronic input/output compensation function that is specifically chosen based on the measured ambient light condition is used to drive the display. Furthermore, according to certain embodiments, the optoelectronic input/output compensation function is selected based on whether a display backlight (230) is turned on or off.

Abstract: A multislot packet data transfer method (300) for a mobile station alters a transmission (370) of a radio block on a last transmission timeslot in a block period (320) immediately preceding an idle frame when the mobile station is in an allowed multislot configuration yet not able to perform normal Base Station Identification Code (BSIC) decoding. The method (300) also skips a last transmission burst in a frame immediately preceding an idle frame (330) in accordance with known extended search window techniques. The method contemplates various criteria (340) for determining when to alter the radio block, which include: whether an unacknowledged radio link control mode is used (350) and whether a robust coding scheme is used (360).

Abstract: An Automatic Repeat-reQuest (ARQ) Reset method for an ARQ transmitter disables (120) transmission, starts (130) an ARQ transmitter window at a first unacknowledged block, and discards (140) service data units (SDUs) in the ARQ transmitter window having zero blocks in a ‘not-sent’ state. Thus, for all SDUs having no blocks in a ‘not-sent’ state, the blocks in an ‘outstanding’ or ‘waiting-for-retransmission’ state are changed to a ‘discard’ state. Next, the ARQ transmitter sets (150) the state of all blocks in partially unsent SDUs of the ARQ transmitter window to ‘not-sent.’ So, any remaining blocks in an ‘outstanding,’ ‘waiting-for-transmission’ or ‘discard’ state are changed to ‘not-sent.’ After the ARQ transmitter enables (160) transmission and ends (190) the ARQ Reset procedure, the ARQ transmitter will send blocks in the ‘not-sent’ state. This ARQ Reset method avoids retransmitting blocks that might cause duplicate packets at the ARQ receiver, which some protocols cannot handle.

Abstract: A method and apparatus may improve success rate and time of call-setup while a mobile station is experiencing high interference. The method checks (255) if a mobile station is experiencing high-interference. This may occur when the mobile station fails to decode a paging channel of a serving cell (235) to read a first page. Upon determining that the mobile station is experiencing high-interference, the mobile station selects a set of cells (260) having the same location area identifier as the serving cell from a list of top neighboring cells, and selects a cell (265) from the set of cells, and synchronizes (270) with a base station of the selected cell. After synchronizing, the mobile station decodes the paging channel of the selected cell (275) and reads a second page from the paging channel of the selected cell including identical information data as the first page.

Abstract: A method and apparatus for detecting a frequency band and mode of operation using recursive sampling and narrowing down is disclosed. The method comprises sampling (215) by a multi-mode wireless communication device, a broad operational frequency spectrum at a first sampling rate to produce a first set of discrete signal samples. Then, the wireless communication device compares (230, 240) at least one of the energy graphs of the first set of discrete signal samples with at least one protocol-specific signature to confirm (245), if an approximate match is found. When one or more approximate matches are found, the wireless communication device narrows down (250) the broad frequency spectrum to a reduced set of frequency band(s) that correspond to the matched protocol-specific signature(s). Then the steps of sampling (215), comparing (230, 240), confirming (245), and narrowing down (250) are recursively followed till a frequency band and mode of operation is confirmed.

Abstract: An improved microphone assembly (128) is provided for porting two microphones (240, 242) of an opposing pair used for beam forming through a single symmetric porting structure (244). The microphone assembly (128) includes a first microphone capsule (240), a second microphone capsule (242) and a porting structure (244). The porting structure (244) encloses the first and second microphone capsules (240, 242) therein and has a first port (251) formed in a first wall (246) thereof and a second port (252) formed in a second wall (248) thereof opposite to the first wall (246), where the first and second microphone capsules (240, 242) share the first port (251).

Abstract: An wireless communication device with an antenna (400) for sending and receiving signals in a plurality of frequency bands generates a plurality of resonances in the plurality of frequency bands and includes a first radiating element (402) that generates a first resonance in a first frequency band, a second radiating element (404), coupled to and extending at an angle from the first radiating element (402), that generates a second resonance in the first frequency band, and a third radiating element (406), coupled to and extended at an angle from the first radiating element (402). A capacitive coupling between the second radiating element (404) and the third radiating element (406) generates a loop with a third resonance in the first frequency band, and the third radiating element (406) generates a fourth resonance in a second frequency band independent of the loop at the second frequency band.

Abstract: A technique for determining a received signal strength indicator of a target base station at a subscriber station includes performing a discrete Fourier transform on a received signal to provide a transformed signal. In this case, the transformed signal occupies one or more segments of a channel and the one or more segments each include multiple subcarriers. A shift-n cross-correlation is calculated based on the transformed signal and a preamble sequence of the target base station to provide a coarse received signal strength indicator for the target base station.

Abstract: A security mode method (200) receives (210) a layer 3 message in a first domain from a network, determines (220) if the layer 3 message has integrity protection information, ascertains (240) if a security mode has been initiated in the first domain, and forwards (260) the layer 3 message to an upper layer, if the layer 3 message lacks integrity protection information and a security mode has not been initiated in the first domain even if security mode has been initiated in a second domain. This method allows a mobile station to process a non-integrity-protected layer 3 message from one domain even if integrity protection has been initiated in another domain. When packet-switched and circuit-switched connections are being concurrently set up, a non-integrity-protected message in one domain may arrive at a mobile station after an integrity protection initiation message in another domain.

Abstract: The invention concerns a method (200) and system for improving transmission or receipt of channel descriptors. The method can include the steps of—in a wireless communication system (100) that periodically broadcasts regular channel descriptors (310) at a set interval (312)—changing (212) a modulation scheme and transmitting (216) one or more supplementary channel descriptors (314) during the set interval between regular channel descriptors. The method can also include the step of periodically transmitting (214) a channel descriptor count (412) that provides an indication of the changed modulation scheme.
