Abstract: In one embodiment, a device (100) having a first portion (102) and a second portion (104), the first or second portion being pivotably adjustable in two directions to reveal the other of the first or second portion, has a biaxially pivotable hinge (106) and a disengagable uniaxially pivotable hinge (108). The biaxially pivotable hinge (106) interconnects the first and second portions (102, 104). The uniaxially pivotable hinge (108) is capable of selectively (a) interconnecting the first and second portions (102, 104) and (b) releasing connection between the first and second portions (102, 104), the selectivity being dependent upon relative rotational position of the first portion (102) and the second portion (104) about the uniaxially pivotable hinge (108).

Abstract: Changing access points for a mobile node (106) in a wireless access network (100), for example a wireless local area network (WLAN), includes the mobile node (106) communicating content data on an initial channel (214) via an initial access point (104) of the wireless access network (100); the mobile node (106) sending a handover request on a new channel (215) to a new access point (105) of the wireless access network (100); the mobile node (106) resuming communication of content data on the initial channel (214) via the initial access point (104); the initial access point (104) and the new access point (105) performing handover steps while the mobile node (106) resumes communication of content; and when the handover steps are completed, the mobile node (106) communicating content data on the new channel (215) via the new access point (105).

Abstract: A method for controlling diversity receivers in a wireless communication device includes the steps of: determining if the wireless communication device is experiencing poor coverage (220), using a first receiver and a second receiver for diversity (230) if the wireless communication device is experiencing poor coverage, and using the second receiver for scanning (240) if the wireless communication device is not experiencing poor coverage. Thus, diversity can be used when needed to improve reception. Both receivers, however, can be used in a non-diversity mode to reduce current drain or to speed up channel acquisition when coverage is not poor.

Abstract: Disclosed are a light guide (750) and an electronic device including a light guide for coupling ambient light to a light sensor. The light guide (750) that is a structure of light-transmitting material having an elongate shape including a first end (752) for receiving ambient light and a second end (754) for collecting ambient light to transmit to a light sensor. The first end (752) of the light guide has a concave shape and the second end (754) of the light guide also has a concave shape. An electronic device may support the light guide and a light sensor. The concave shape of the second end of the light sensor may disperse light toward the light sensor, rather than tightly focusing the light toward the light sensor. Accordingly, the light sensor may have a sensing area that forms a detection plane so that the detection plane is positioned adjacent to the second end.

When the compact input device (104) is in an extended and aligned configuration, the keys of the first extendable interlocking part (402) and the keys of the second extendable interlocking part (404) form a common QWERTY keyboard configuration.

Abstract: A push-to-talk (PTT) radio resource controller (441) establishes a “reverse” channel using a forward channel resource request module (461), a reverse channel resource request module (463), an allocation rules module (470) that is coupled to the forward channel resource request module (461) and the reverse channel resource request module (463), and a channel resource availability module (480) that is coupled to the allocation rules module (470). A method (300) for establishing a reverse channel in a PTT system initiates a forward PTT circuit (313) between an originating device and at least a first called device, initiates a first reverse PTT circuit (319) between the first called device and the originating device before releasing (329) the forward PTT circuit, and then releases (339) the first reverse PTT circuit.

Abstract: An emergency call placement method (300) used in user equipment in idle mode camped on a first cell of a wireless communication network having a first radio access technology includes the steps of requesting (316) a radio resource control connection using “emergency call” as an establishment request, changing (340, 350) to a new cell in a different location area or routing area than the first cell, and requesting again (316) a radio resource control connection using “emergency call” as an establishment request. This method avoids performing a location area update or a routing area update when the user equipment changes to a new cell during an emergency call and thus may speed up placement of the emergency call by several seconds.

Abstract: A communication device (100) having intelligent communication management includes a processor (115), a memory (120), and a communications manager application (140). The communication device (100) sequentially initiates communication with a contact either automatically (e.g., based on a preset communication preference) or in response to user input using various communication means associated with the contact. The contact and the associated communication means are stored in the memory (120). When a communication connection is disconnected or not able to be established, the communications manager application (140) identifies the next communications means to which to initiate a communication with the contact.

Abstract: A communication group is activated within a communication system (100) including an administrator device (125) and at least one subordinate device (130,135). Each subordinate device (130,135) is programmed with a set of operation rules dependent upon communication source (300), information content (305), current time (310), or geographic location (315). The administrator device (125) dynamically changes the stored set of operation rules for the subordinate device (130,135) by communicating a change message.

Abstract: A method (200) in a CDMA terminal device for acquiring a system identified in an enhanced preferred roaming list (enhanced PRL), with at least one entry containing a mobile country code, includes the steps of obtaining (210) system identifiers from SYNCH channels on a scan list, determining (220) if the system identifiers match entries on the enhanced PRL, and inserting (226) channel information items on a first list if the system identifiers do not match entries on the enhanced PRL. If all channels on the scan list have been scanned without any system identifiers matching entries on the enhanced PRL, the method obtains (246) mobile country codes using channel information items from the first list, determines (250) if the mobile country codes match entries on the enhanced PRL, and camps (283) on a system if its mobile country code matches an entry on the enhanced PRL.

Abstract: While engaged in a dedicated channel, a User Equipment (UE) may get stuck on it. A method and the computer program product detects whether the UE is stuck on the dedicated channel (202). When it is detected that the UE is stuck, the UE or the corresponding network in which the dedicated channel is located carries out a local release of the UE from the dedicated channel (204), and the UE is placed in idle mode (206). Locally releasing the UE from the dedicated channel curtails unnecessary battery consumption in the UE and limits wastage of network resources and bandwidth.

The second circuit board (104) includes an antenna (116) for receiving and transmitting radio waves.

Abstract: An intermediate code and electronic device therefore uses a method for character entry that has the steps of entering a first character code into a memory buffer (320, 360, 390), entering an intermediate code into the memory buffer (310, 350, 380), entering a second character code into the memory buffer (332, 378), changing the intermediate code to one or more character codes (333, 336, 365, 375, 393, 396), and using a display engine to display one or more characters represented by the first character code, the one or more character codes, and the second character code. These intermediate codes are useful for reduced keypads where certain characters, such as ligatures, are difficult to access from the keypad.
