The system employs a ground-based, central control system for managing access to the satellite-based transponder so that the aggregate power spectral density (PSD) of the RF ... 01/25/07 - 20070021062 - Power mode control for a communication device A communication device may include a power source, a transmitter configured to transmit radio frequency signals to a satellite via a satellite-based network and a receiver configured to receive radio frequency signals from the satellite via the satellite-based network. The communication device may also include logic configured to receive power ... 01/25/07 - 20070021061 - Current detector with variable output voltage level A current detector with variable output voltage level. The current detector includes an operational amplifier, an adjusting circuit, a load circuit for detecting current running therethrough, and a clamping circuit. The operational amplifier includes a non-inverting input, an inverting input, and an output. The operational amplifier is connected to an ... 10/19/06 - 20060234626 - Broadband high efficiency traveling wave tube amplifier system A power control system for a satellite receiving radio-frequency signals includes a traveling wave tube amplifier system and corresponding traveling wave tube. An anode voltage of the traveling wave tube amplifier system is used to modulate or saturate the current of the electron beam of the traveling wave tube so ... 05/25/06 - 20060111041 - Aggregate radiated power control for multi-band/multi-mode satellite radiotelephone communications systems and methods A satellite radiotelephone system includes a space-based component that is configured to communicate with multiple radiotelephones over multiple frequency bands and/or multiple air interfaces. An ancillary terrestrial network is configured to communicate terrestrially with the multiple radiotelephones over substantially the multiple frequency bands and/or substantially the multiple air interfaces. An ... 05/04/06 - 20060094352 - Apparatus and methods for power control in satellite communications systems with satellite-linked terrestrial stations A signal power control loop is provided for a link between a terrestrial station and a terminal when the terminal and a satellite are linked via the terrestrial station. The signal power control loop may control transmitted signal power of the terminal and/or the terrestrial station. In some embodiments, the ... 02/23/06 - 20060040614 - Return link design for psd limited mobile satellite communication systems A system and method for managing access to a satellite-based transponder by a plurality of aircraft each having a mobile radio frequency (RF) system. The system employs a ground-based, central control system for managing access to the satellite-based transponder so that the aggregate power spectral density (PSD) of the RF ... 10/20/05 - 20050233695 - Apparatus for controlling power of external device in audio receiver Embodiments of a method and an apparatus for controlling power of an external device in an audio receiver can reduce unnecessary power consumption of the external device. The apparatus can detect a potential, a level or the like of a speaker output signal from the audio receiver and control the ... 06/02/05 - 20050118949 - Method for detecting an oscillation in an on-frequency repeater A method of detecting oscillation in an on-frequency repeater having an RF signal path coupled between an input antenna and an output antenna. In accordance with the present invention, a first RF signal power level within the RF signal path is detected during an un-muted period in which transmission of ... ### FreshPatents.com Support |
