摘要： A vehicle mounted communication system comprises a hand held mobile phone and a hands-free unit. The hand-held unit includes a wide area transceiver for station outside of the vehicle and a short-range radio transceiver the hands-free unit includes a microphone and speaker and is mounted in a fixed location in the vehicle. A short range radio link operatively connects the hand-held unit and the hands-free unit to enable voice and data signals to be exchanged between the hand-held unit and the hands-free unit. The hands-free unit may include a programmable memory unit to store a user table containing user identification data and configuration data. The hands-free unit control logic configures the hands-free unit based on the user identification received from the hand-held unit, thus allowing multiple users to have their preferences recognized by an individual hands-free unit. The programmable memory unit and control logic may be incorporated into the vehicle's internal network for control of things like electric seats, stereo controls and the like.

摘要： A communication system provides efficient satellite communication in rural, remote, or sparsely populated areas, or in areas lacking a conventional telephone infrastructure, or in special purpose uses such as airport coverage. Subscribers in such areas communicate with the satellite via a simple, highly modular entry node located in a local area to be served. Subscriber units provide subscribers with access to the system. The subscriber units are connected to the entry node via local access loops provided by point-to-point wireless links between the subscriber units and the entry node. The entry node internally switches local traffic among subscribers and connects traffic to outside circuits, via wireless links with the satellite, as appropriate. The outside circuits are provided by the cooperative working of the satellite, an entry-node controller, and an earth station. The wireless links between the satellite and the entry node and the local access loops may operate at the same or different frequencies. If they operate at different frequencies, a frequency translator in the entry node controller matches the different frequencies. A subscriber unit may be used to provide the subscribers with access to the system such that speech compression and decompression takes place in the subscriber unit itself to avoid the effects of tandem coder/decoders.

摘要： A miniaturizable wireless communications device is configured to redefine the roles of the primary front and rear surfaces of the device by positioning a large graphic display on the forward surface and a speaker on the rear surface. The associated keypad can be disposed on either or both of the rear surface or the graphic display (such as via a touchscreen). Alternatively, a pivotable flip can include the keypad and even the microphone. During operation, a user can turn the device around to orient the desired input surface for use (forward face up for display surface use and forward face down or away for telephone use). An associated method of designing the operational platform of a wireless communications device so that it has two active primary faces is also disclosed.

摘要： An approach to managing stored-value data objects, such as electronic tickets, comprises secure systems and procedures for ticket issuing, storage, and redemption. With these systems and procedures in place, stored-value data objects may be securely transferred to remote systems, such as a user's personal electronic device, for subsequent secure redemption, thus allowing the user to gain access to the desired goods or service upon redeeming the data object. Techniques provide secure delivery of the requested data object to the requesting device, and provide secure redemption and disposal of the data object. Ticket issuing systems may be Internet-accessible systems, and users may purchase and redeem tickets using mobile terminals or other devices adapted for wireless communication. Standardized WPKI and Internet access procedures may be employed in ticket issuance and redemption. Techniques further provide temporary and rapid verification data objects useful where rapid ticket verification is essential, such as mass transit systems.

摘要： A radiotelephone includes a multifunctional headset that operates in two different modes. According to a first mode, the headset may be mounted on a radiotelephone body where it serves as a speaker and microphone for the radiotelephone. Also, the headset can be separated from the body of the portable radiotelephone and placed on the head of the user. In this mode of operation, the headset receives and transmits signals from and to the radiotelephone body during a call, thus providing hands-free operation. The headset can be attached to a user's head by an ear clip. The headset and body may include low power RF transceivers. The headset may contain power saving circuitry to minimize power drain from an internal battery. The battery may be recharged whenever the headset is fixed to the radiotelephone.

摘要： A communication system and method for transmitting relatively short data messages in the communication system. A dedicated frequency is sequentially switched into each of a plurality of satellite beams or traffic channels to transmit data messages at an increased power level to provide an increased signal margin. The increased power level of the dedicated frequency can be combined with coding and bit and message repetition to further increase the signal margin.
