Abstract: A mobile device (104) interacts with a media collection system (102). The media collection system has a communication nodes (106) placed at various locations in a region, area, or facility where the mobile device may be carried by a user. The mobile device interacts (306) with the media collection system over a short range radio link (206) to request media collection service. The media collection system then uses media collection devices (107) in the same region, area, or facility as the communication nodes to record media, thereby producing a record of the user's experiences in the region, area, or facility. The collected media is stored on a database (112) which accessible by the user using an access identifier.

Abstract: A mobile communication device (100) includes a receiver (102) which is normally shut off when the mobile communication device is idle. Upon the arrival of a paging time slot to which the mobile communication device is assigned, the mobile communication device turns on the receiver and begins receiving a composite signal including frequency diverse subchannels. The mobile communication device measures the delay spread of the subchannels (406). The receiver then adjusts the receiver on time for the next time slot based on the delay spread of the present time slot.

Abstract: A transmitter device (100) receives an audio signal from an audio source device (112), and transmits the audio signal at a low power over a commercial broadcast channel to a local receiver (120). The transmitter device selects an initial channel by scanning the available spectrum, partitioned into sub-bands (210-206), and measuring the received signal strength in each channel. The channel having the lowest strength is used to set a threshold. The sub-band with most channels meeting the threshold is initially selected, and the channel in the initially selected sub-band with the lowest received signal strength is selected for initial use. A context-based weighting factor may be applied in selecting the initial channel or in selecting subsequent channels when the initial channel conditions degrade.

Abstract: A mobile communication device (100) downloads an application file (300), which includes an application (302) and a menu parameter set (306).

The mobile communication device maps the application's standardized category to one of the custom categories, and adds the application name to the custom category.

Abstract: A substrate (104) has a region of conductor segments (110) and a matrix display driver (106) mounted on it. The matrix display driver is used for creating pixilated images or symbols, while the conductor segments are used for turning on or off iconic elements. An encapsulated electrophoretic display laminate (108) is mounted over both the matrix display driver and the region of conductor segments to form the mixed mode display.

Abstract: A multi-mode communication device (100) uses a quadrature transmitter (102) for transmitting both amplitude and constant envelope angle-modulated signals. For angle modulation, a separate feedback path is used from that used for amplitude modulated signal transmission. An FM receiver (136) is used to produce error signals (214, 216) used in correcting the I and Q quadrature signals (206, 208).

Abstract: A quadrature modulated transceiver (102) is used to generate a constant envelope angle modulated signal for communications. To produce the required feedback when operating in the constant envelope mode, an orthogonal frequency division multiplexed receiver (136) is used.

Abstract: A device (100) includes an AM generating circuit (106) which couples interference (132) into another part of the device (124). A second AM signal (304) is generated, having inverse modulation relative to the first AM signal, and is coupled to the affected part of the device to counteract the interference by reducing the effective harmonic content of the first AM signal.

Abstract: A speech filter (108) enhances the loudness of a speech signal by expanding the formant regions of the speech signal beyond a natural bandwidth of the formant regions. The energy level of the speech signal is maintained so that the filtered speech signal contains the same energy as the pre-filtered signal. By expanding the formant regions of the speech signal on a critical band scale corresponding to human hearing, the listener of the speech signal perceives it to be louder even though the signal contains the same energy.

Furthermore, the method includes playing (204) the decoded audio data over the audio output device.

Abstract: A mobile communication device (100) uses a local wireless transceiver (108) to establish an asynchronous link (202) with a remote audio processor (110) which is typically operated in a low power mode and that maintains an association between the mobile communication device and remote audio processor. When the mobile communication device receives an incoming call page (210), the mobile communication device initiates a synchronous link with the remote audio processor, and responds to the incoming call page at a time when the call will be connected only after the synchronous link is established.

Abstract: A pitch adaptive circuit (200) includes an equalizer control circuit (206) that evaluates the pitch of the speech signals that are being processed and depending on the pitch information, the equalizer control circuit (206) selects an equalizer (208, 210) to shape the decoded speech signals. By selecting the best equalizer (208 or 210) to use based on the pitch information, improvements in audio quality are provided automatically without user intervention.

Abstract: A mobile communication device (100) includes a camera module (102) which provides an image stream when the camera module is active. The image stream is used to display images on a display (114) to provide a viewfinder function so that a user of the mobile communication device can see to what the camera is aimed. While the mobile communication device is operating in camera mode, the mobile communication device receives a signal at a radio receiver (104) during a time slot of a time division multiple access frame (110). To prevent the camera module from interfering with the receiver operation, the camera module operation is suspended during the receiver time slot.

Abstract: A mobile communication device (100) contains a local wireless controller (114) for operating with a remote audio processor (124). The remote audio processor is used for listening to and speaking with remote parties via the mobile communication device, and operates in a mode having a relatively long latency in communicating with the mobile communication device. Upon receiving a dispatch call (306), a baseband processor (108) of the mobile communication device notifies an application processor (110) with a high priority dispatch notification (122). The high priority dispatch notification causes an active link to be established between the mobile communication device and remote audio processor sooner than if were to occur with ordinary call processing.
