Abstract:
A PTT bridging gateway between a first PTT system and a second disparate PTT system: receives an invitation to a first client to join a first group call for a first group comprising multiple member clients on the first PTT system, wherein the first client is one of the member clients of the first group; determines that the first client is mapped to a second group comprising multiple member clients on the second PTT system; and initiates a second group call to the multiple member clients on the second PTT system.

International Classification:

US Classification:
370312
Abstract:
Techniques are provided for determining whether a particular Access Point (AP) is to be designated as an Infrastructure Access Point (IAP) or a Backhaul Mesh Access Point (BMAP) based on the connectivity of the particular AP to a network which includes at least one multicast heartbeat message (MCHBM) source. Techniques are provided which can allow an Infrastructure Access Point (IAP) to change its device type to a Backhaul Mesh Access Point (BMAP) device type when the IAP determines that connectivity to the network is lost. Other techniques are provided which can allow a Backhaul Mesh Access Point (BMAP) to change its device type to an Infrastructure Access Point (IAP) device type when the BMAP determines that connectivity to the network is established.

Abstract:
A method of operating an automotive location system may include providing a timely warning if the system cannot satisfy predetermined performance criteria. An example method may include ascertaining a satellite-based position estimation ascertaining a dead reckoning position estimation, determining a location estimation by combining the satellite position estimation and the dead reckoning position estimation, determining a map-matching position, and determining an integrity of the location estimation by comparing a test statistic calculated by evaluating the map-matching position and the location estimation with a decision threshold based upon a predetermined location estimation accuracy specification. If the test statistic is less than the decision threshold, the system may provide the location estimation. If the test statistic is greater than the decision threshold, the system may provide an indication that the integrity of the location estimation does not satisfy the predetermined location estimation accuracy specification.

US Classification:
455518
Abstract:
Critical resource data () required for a group call can be identified. Controlling () and secondary () PTT communications systems can communicate using an expanded network-to-network interface (NNI) (). Allocation of identified critical resources () can be requested () for the group call from the secondary PTT communications system (). In response to a successful allocation of the requested critical resources by the secondary PTT communications system, the group call can be authorized by the controlling PTT communications system (). The allocated critical resources of the secondary PTT communications system () can be used to establish the group call.

Abstract:
A medication patch compliance control unit system and method is disclosed. The control unit can include an attachment sensor, a user interface and a controller that receives signals from the attachment sensor and sends signals to the user interface. The control unit can include an attachment sensor, a wireless transceiver and a controller that receives signals from the attachment sensor and sends signals through the transceiver. The attachment sensor can be a temperature sensor, and the controller can determine attachment based on whether the sensor is reading temperatures in the normal body temperature range. The user interface can include visual and/or audible indicators. The control unit can include an expiration timer, and provide an expiration signal when the patch is expired. The transceiver can transmit medication patch data to a healthcare provider. The controller can record when the medication patch is attached to and detached from the patient.
Method And Apparatus For Managing Quality Of Service Settings For Group Communications

US Classification:
370260
Abstract:
A centralized quality of service (QoS) entity having a processing device performs a method for managing QoS settings for group communications. The method includes: determining a plurality of active participants of a group communication session; and determining, for each active participant, an individual QoS setting, including a first individual QoS setting for a first active participant. The method further includes modifying the first individual QoS setting based on the individual QoS setting for at least one other active participant, wherein the modified first individual QoS setting is applied to a session leg used by the first active participant during the group communication session. The active participants of the group communication session can be on the same or heterogeneous wireless networks.

A method for rapid peer-to-peer link establishment among a set of mobile devices includes operating a first second device, advertising system attributes in a wireless beacon by the second device, receiving the system attributes from the wireless beacon at the first device, comparing the system attributes to a service needed by the first device, and, if the second device is compatible based on the comparing, establishing a wireless link by the first device to the second device. A system and wireless device for rapid peer-to-peer link establishment among a set of mobile devices are also described.
Optical Cable For Transmission Of Audio And Video Signals
- Nantong, CN Zuodng WANG - Beijing, CN Wei MAO - Palo Alto CA, US Yun BAI - Beijing, CN
International Classification:
H04B 10/25
Abstract:
Systems and methods for optical transmission of one-or-more out-of-band signals associated with audio-video signal communication are described. In one aspect, an optical receiver receives a first out-of-band electrical signal and a second out-of-band electrical signal from a video sink. The first out-of-band electrical signal may correspond to an audio-video stream previously received or concurrently being received from a video source optical transmitter at the optical receiver. The second out-of-band electrical signal may also correspond to the audio-video stream. The optical receiver may combine the first out-of-band electrical signal and the second out-of-band electrical signal into a transmit electrical signal. In one aspect, the optical receiver converts the transmit electrical signal into an optical signal, and transmits the optical signal to an optical transmitter via an optical communication channel.
