    • A communications system including devices (10, 20) for transmitting and receiving wireless communications over licensed and unlicensed bands is disclosed. On the transmit side, a device (10) includes a plurality of message sources (8A, 8B, 8C) and a smart router (12) function executed by a processor (30) within the device. The smart router (12) function allocates each wireless transmission, or components of a multicomponent wireless transmission, over a licensed wireless link (LLTX) or an unlicensed wireless link (ULTX), by optimizing various factors. The allocation factors include the availability of the unlicensed and licensed channels within range of the transmitting device (10); quality of service parameters such as time delay limits, jitter limits, bandwidth requirements, and the like; cost tolerance and cost per minute factors; power consumption expectations; and a combination of these and other factors. Transmission of the wireless message over the selected wireless links is then carried out. A receiving device (20) may include a smart receiver (22) that resequences the components of a multicomponent transmission for forwarding to output functions (24A, 24B, 24C) of the receiving device (20).

    • In one embodiment, an automated emergency alert system includes a handheld portable communication device operable to initiate communication over a wireless telecommunications network, a dynamic sensor operable to generate an acceleration profile for the device, and a memory operable to store one or more predefined acceleration profiles each associated with an emergency event. The system also includes one or more processors collectively operable to (1) receive from the dynamic sensor an acceleration profile for the device; (2) access one or more of the stored predefined acceleration profiles; (3) compare the received acceleration profile to the one or more stored predefined acceleration profiles to determine if the acceleration profile substantially matches a predefined acceleration profile; and (4) if it is determined that the acceleration profile substantially matches a stored predefined acceleration profile, initiate a communication using the network to one or more emergency call centers to notify the call center that the emergency event has occurred.

    • A location determination apparatus, method and system (10, 23, 26, 32, 36, 48, 52, 60, 64, 74, 78, 84, 90, 106) that is an improvement upon existing location determining techniques. The invention enables precision indoor location determination through the use of non-DTV terrestrial broadcast signals (e.g. one way, wide area, dissemination of information)(20), or re-broadcast signals (44, 56, 70, 80) of the proposed (terrestrial based) digital satellite radio relay transmitters (42, 54) to provide position location. This solution does not require a local receiver to correct for long distance propagation dispersion, particularly for the satellite relay, as the digital radio satellites are already synchronized to GPS time. More specifically, the invention discloses two significant location detection concepts: A) local terrestrial transmitters (12) provide information used to determine the location of an electronic apparatus; and B) local re-transmitters of satellite-distributed programming (42, 54) provide information used to determine the location of an electronic apparatus.
    • 一种位置确定设备,方法和系统(10,23,26,32,36,48,52,60,64,74,78,84,90,106),其是对现有位置确定技术的改进。 本发明通过使用非DTV地面广播信号(例如,单向,广域,信息传播)(20)或重新广播所提出的广播信号(44,56,70,80)的信号来实现精确的室内位置确定 (地面)数字卫星无线电中继发射机(42,54)以提供位置定位。 该解决方案不需要本地接收机来校正长距离传播色散,特别是卫星中继,因为数字无线电卫星已经与GPS时间同步。 更具体地,本发明公开了两个重要的位置检测概念:A)本地地面发射机(12)提供用于确定电子设备位置的信息; 和B)卫星分布式节目(42,54)的本地重新发射机提供用于确定电子设备的位置的信息。
