摘要： A system and method of communications usage management for multiple networked devices such as cellular telephones in a telecommunications network. A management database is provided for storing communications attributes for at least one networked device. The stored communications usage attributes serve as criteria for regulating access of the networked devices to the system. The users of the devices may purchase a quantity of transferable units, such as usage minutes over the system network, with the units being redeemable for goods and/or services on the system, thus facilitating transfer of units between users. A user interface is provided as a system management device for accessing the management database to configure the communications usage attributes for defining the transfer and usage criteria. Communications usage software operable with the network devices computes usage times to provide an accounting of usage and regulation in accordance with the management database. In the described embodiment, short message service (SMS) traffic is used for messages between networked devices used by several users to purchase quantities of redeemable units for exchange, commercial activities, or recreation which may be facilitated through the system operator.

摘要： An amplifier system to increase the efficiency of amplification systems that employ linear modulation schemes. The amplifier system has a signal amplifier for receiving a constant amplitude input signal and producing an amplified version of the input signal. A variable impedance network presents various impedances to an output of the signal amplifier responsive to a load control signal. An envelope mapping circuit coupled to the variable impedance network produces the load control signal responsive to a desired amplitude modulation (AM) envelope. The various impedances causes the desired AM envelope to be impressed upon the amplified version of the input signal.

摘要： A transmitter (107) includes amplifying circuitry (203) and control circuitry (215, 217, 219) for biasing the amplifying circuitry (203) so that it operates closer to saturation with increased efficiency. The gate voltage signal (213), which provides a gate bias, is coupled to the amplifying circuitry (203) and is dynamically varied by the processor circuitry (219) in response to the value of the amplifier control voltage (211) coupled to the amplifying circuitry (203). The amplifier control voltage (211), which has a value for maintaining the output power of the amplifying circuitry (203) at a constant, is produced by the integrating circuitry (217) in response to a comparison of the detected power output signal (216) produced by the detecting circuitry (215) and the power output control signal (218) produced by the processor circuitry (219). Efficiency is realized by dynamically varying the gate voltage signal (213) to its largest magnitude so that the amplifying circuitry (203) may operate as close to saturation as possible while still maintaining a constant output power.

摘要： A communication device performs a method for detecting presence of a jamming signal. The method includes retrieving a scan list comprising multiple radio channels within a first frequency range of operation of the communication device. The method further includes scanning at least a subset of the channels on the scan list to determine, for each scanned channel, whether energy that exceeds an energy threshold is detected on the scanned channel. Moreover, the method includes determining a first quantitative measure based on a first plurality scanned channels having energy that exceeds the energy threshold, and comparing the first quantitative measure to at least a first jamming signal detection threshold. Additionally, the method includes indicating, on the communication device, presence of a jamming signal when the first quantitative measure satisfies the at least a first jamming signal detection threshold.

摘要： A method and system performs antenna tuning to minimize interference affecting signal reception within a wireless communication device. An antenna tuner controller determines whether the wireless communication device concurrently provides (a) simultaneous signal transmission and reception and (b) dual signal propagation. In response to determining that the wireless communication device concurrently provides the simultaneous signal transmission and reception and the dual signal propagation, the antenna tuner controller determines a current mode of operation corresponding to simultaneous signal transmission and reception and the dual signal propagation. Based on the mode of operation determined, the antenna tuner controller identifies a priority for performing antenna isolation to minimize interference affecting signal reception when the wireless communication device actively communicates within the specific mode of operation. In response to the identifying the priority for performing antenna isolation, the antenna tuner controller performs antenna impedance tuning that provides antenna isolation corresponding to the priority.

摘要： Methods and apparatus for serving content to a wireless device (106) are disclosed. In an embodiment, a gateway (114), or any other suitable device or system, determines that at least one message (e.g., a text or text-like message) containing a first pointer (e.g., a unicast URL) to the content (e.g., a web page) is to be transmitted via an emergency alert system (e.g., CMAS). In response thereto, the gateway (114) obtains the content using the first pointer and generates a second different pointer (e.g., a multicast/broadcast URL) to the content. The gateway (114) provides at least a portion of the at least one message and the second pointer for transmission via the emergency alert system (118). The gateway (114) also provides the content for transmission via a wireless multicast/broadcast channel (120) based on the second pointer.

A radar transmitter is operatively coupled to the radio frequency modulation circuitry, and is operative to transmit a radar signal including the video data. The apparatus may also include radio frequency demodulation circuitry and a video decoder. The video decoder is operative to decode video data contained in a radar signal demodulated by the radio frequency demodulation circuitry. An inter-vehicle alert system controls the camera to initiate capturing video data which includes the video data. A method of operation modulates a radar signal to include at least a portion of the video data captured in response to detecting an obstruction, and transmits the radar signal to a second vehicle via an antenna array oriented at the moving vehicle's rear.
