摘要： An electronic device and a remote device cooperate to enable a display of an electronic device when a distance between the electronic device and the remote device is less than a transmit range and to disable the display when the distance is greater than the transmit range. Disabling the display of the electronic device may improve the security of data on display. Moreover, the disabling and enabling of the display may be carried out automatically, thereby possibly relieving the authorized user from logging out or powering-off the electronic device to secure the display. When the authorized user carries the remote device, the display may be enabled and disabled as the user moves relative to the electronic device. The display of the electronic device may be enabled when the electronic device and the remote device are located within a first distance and the display is disabled when the remote device is located a second distance from the remote device, wherein the second distance is greater than the first distance. For example, when the user carries the remote device, the display is enabled when the user is within a first distance from the electronic device. When the user carriers the remote device to a second greater distance from the electronic device, the display is enabled.

摘要： In accordance with one embodiment of the present invention, in a wireless telecommunications system, an automatic gain control loop for a base station, comprises a demodulator having at least one output terminal. The demodulator is adapted to demodulate signals received by the base station so as to provide a plurality of phase signals via its output terminals. These phase signals correspond to the phase of the signals received by the base station. A plurality of variable-gain amplifiers are adapted to receive one of the phase signals and to change the amplitude of said phase signals. A plurality of signal processing units are adapted so as to receive signals provided by the variable amplifiers, and each of the signal processing units is further adapted to generate a feedback control signal so as to control the gain of each one of the variable-gain amplifiers. In accordance with another embodiment of the invention, a method for controlling the gain of signals received by a base station in a cellular communication system comprises the steps of demodulating the signals so as to generate phase signals corresponding to the received signals, variably controlling the magnitude of each one of the phase signals based on a feedback control signal, and processing the phase signals so as to generate the feedback control signal.

摘要： Techniques are provided herein to optimize up-link transmission power from a wireless terminal to a base transceiver station in a multicarrier system. A pathloss between the wireless terminal and the base transceiver station is determined. A determination is made if the pathloss is less than or larger than a predetermined value. One or more sub-carriers are assigned to the wireless terminal based on whether the pathloss between the wireless terminal and the base transceiver station is less than or larger than the predetermined value. A power cap command signal is sent from the base transceiver station to the wireless terminal for limiting a maximum allowable power transmitted by the wireless terminal to a predetermined level based on proximity of the one or more sub-carriers to an edge of a frequency band used for up-link transmissions made by the wireless terminal.

摘要： A wireless user terminal operates in a mode that is selected based on an indication of the orientation of the wireless user terminal from a gravitational sensor in the wireless user terminal. When the wireless user terminal is in a first orientation, the wireless user terminal operates in a speakerphone mode. When the wireless user terminal is in a second orientation, the wireless user terminal operates in a handset mode. The mode of operation of the wireless user terminal transitions based on movement of the wireless user terminal from the first orientation to the second orientation. For example, when the wireless user terminal placed in a horizontal orientation, one of the speakerphone modes is selected. When the user picks up the wireless user terminal, the wireless user terminal transitions to handset mode. In a personal speakerphone mode, the volume to a handset speaker in the wireless user terminal is increased so that a call may be carried on without holding the wireless user terminal near the user's ear and mouth. In a conference speakerphone mode, the wireless user terminal transmits/receives audio signals to/from an external speaker and external microphone.

摘要： Wireless communications devices using a given speaker for both handset and speakerphone operation are equipped with a mechanical spacer that automatically inhibits the user from placing the speaker in close proximity to the user's ear when the wireless communications device is in speakerphone mode. The spacer is moved from a normal position to a blocking position to switch the device from handset to speakerphone mode. The mechanical spacer may take a variety of forms, such as an articulating antenna, a moveable frame, a moveable speaker flap, and the like. The extra space between the speaker and the user's ear mandated by the presence of the spacer allows the sound generated by the speaker in speakerphone mode to dissipate somewhat before reaching the user's ear, even when the speaker is held as close as possible, thereby automatically providing hearing protection when the wireless communications device is configured for speakerphone operation. In addition, when wireless communications devices incorporating the present invention are in handset mode, the audio level from the speaker is attenuated before reaching the user's ear. This attenuation may come from electronic means, such as by using a lower amount of amplification, or from mechanical means, such as by blocking or otherwise diminishing the sound generated by the speaker, or both. Thus, a wireless communications device incorporating the present invention automatically provides hearing protection during both handset and speakerphone modes of operation.
