Abstract: Disclosed herein are methods and systems for patching direct-mode talkgroups among dual-watch mobile radios. A mobile radio has first and second receivers, and is in a first talkgroup having a first channel. The mobile radio resides the first receiver on the first channel, and detects either a first patch event or a second patch event. The first patch event is an instruction for a first-channel session. The second patch event is an invitation for a second-channel session. Upon detecting the first patch event, the mobile radio transmits an invitation on the first channel and also on one or more other channels respectively associated with one or more other talkgroups, directing all recipients to the first channel. If the mobile radio detects the second patch event, the mobile radio resides the second receiver on the second channel.

Abstract: Disclosed is an integrated LED package for a client device. The integrated LED package includes a flash LED chip, an IR LED chip, and an optional reflective element. The IR LED chip includes an IR LED that emits a cone of IR light, for example, to send commands to another client device such as a TV, to control the TV. The reflective element modifies the cone of IR light such that a TV positioned in front of the client device is likely to receive IR light emitted from the client device. The integrated LED package includes a common anode for both the flash LED and the IR LED. Thus, the integrated LED package may reduce its overall size in comparison to a LED package that does not include a common anode, e.g., the LED package includes a separate anode each for the flash LED and the IR LED.

Abstract: A scan driving circuit is provided. The scan driving circuit for driving cascaded scan lines includes a scan driving circuit, a latch module, a driving-signal generation module, an output control module, a high gate voltage source, and a low level gate voltage. The scan driving circuit of the present invention conducts a driving operation for the latch module by a first cascade signal and a second cascade signal, so that a clock signal is not required to be processed with a phase inversion, and thereby the scan driving circuit has less overall power consumption.

Abstract: A subscriber device joins a talk group and receives, via a control channel, parameters defining a plurality of assigned downlink data transmission periods associated with the talk group on a downlink short data channel. The subscriber device determines from the parameters when a next downlink short data transmission for devices in the talk group will be transmitted on the downlink short data channel. The subscriber device switches to the downlink short data channel during the next transmission period.

Abstract: In at least one embodiment, a radio access network (RAN) device maintains a proxy mapping table (PMT) of any mobile radios that are currently registered with the RAN via a mobile subscriber unit (MSU). The PMT indicates, for each mobile radio listed in the PMT, the particular MSU via which that particular mobile radio is registered with the RAN. The RAN device receives a first service request for a first mobile radio that is listed in the PMT as being registered with the RAN via a first MSU and, in response to receiving the first service request, makes a determination that an air-interface link is available for communication between the RAN and the first MSU. In response to making the determination, the RAN device communicates the first service request via the available air-interface link to the first MSU for delivery to the first mobile radio.

Abstract: A communication device receives coordinates for an inner area and an outer area associated with a geo-fence. The communication device determines its current location coordinate and determines how the current location coordinate relates to the coordinates for the inner area and the outer area. The communication device discovers, using the current location coordinate and the coordinates for the inner area and the outer area, that the communication device is located outside of the inner area and inside of the outer area. Responsive to the discovering, the communication device sends a query to a network equipment to determine the current location of the communication device relative to the geo-fence. The communication device receives information associated with an intermediate area and uses the information associated with the intermediate area to determine the current location of the communication device relative to the geo-fence.

Abstract: A method and apparatus for detecting a stale number. A stale number detection device obtains a call number, a call number contact creation date, and a call number issue date for the call number. The stale number detection device determines that a stale number state exists when the call number issue date is later than the call number contact creation date. The stale number detection device generates a stale number notification based on the stale number state.

Abstract: A mobile radio has selectable transmit and receive channels, and is in a talkgroup that has a primary channel and multiple auxiliary channels. The mobile radio receives a broadcast-start command, and responsively selects its transmit channel to be the primary channel (if available) or an inactive auxiliary channel (if the primary channel is not available). The mobile radio receives user media via its user interface, and transmits that received user media on its selected transmit channel. The mobile radio scans for an auxiliary channel transitioning from inactive to active. Responsive to detecting such a transition, the mobile radio selects that auxiliary channel as its receive channel. The mobile radio mixes inbound media received on its selected receive channel with user media received via its user interface, and transmits the mixed media on its selected transmit channel.

Abstract: A GOA circuit and LCD are disclosed. The GOA circuit includes cascaded GOA units and a control module. Each of the GOA units is driven by a first level of transfer clock, a second level of transfer clock, a first control clock and a second control clock to charge horizontal signal lines corresponding to a display area. The control module masks the first level of transfer clock and the second level of transfer clock when all of the horizontal signal lines are charged completely by the GOA circuit, such that the gate driving signals on the horizontal signal lines are discharged until the level equals to the predetermined level. In this way, the horizontal signal lines are prevented from generating redundant pulse signals before the first gate driving signals are outputted, which ensures the normal operations of the GOA circuit.
