Abstract: A method of detecting and removing ice and/or snow on a communication antenna is presented. In the method, environmental data indicating at least one current environmental condition is received. An optical signal is transmitted from a signaling structure of the communication antenna toward a reflecting surface of the antenna. The optical signal is received at the signaling structure upon returning from the reflecting surface. The returning optical signal is then processed to determine at least one characteristic value of the returning optical signal. The reflecting surface is then heated if the environmental data indicates that ice or snow accumulation on the communication antenna is possible, and the at least one characteristic value of the returning optical signal is outside a predetermined range.

Abstract: A remote control includes a top portion with programming receiver functionality selection members and a bottom portion with a keyboard. The two portions are rotatable between a closed position (where the top portion covers the keyboard) and an open position (where portions of the keyboard project laterally out from under the top portion). When the two portions are in the open position, the selection members and the keyboard share an orientation. The remote control may transmit signals to a programming receiver. The programming receiver may update a display based on signals received from the remote control device. In some implementations, the updated display transmitted by the programming receiver may be based at least in part on a context of a previous display. In various implementations, the remote control may provide indicators to a user. These indicators may be based on signals received from a programming receiver.

Each of the receivers also relays the information to the user of the receiver if the geographic code indicates that the receiver is located within the geographical area.

Abstract: Disclosure is generally directed to a television receiver with multiple inputs, some accepting a local broadcast and some accepting satellite transmissions or transmissions across another network. The television receiver may pass local transmissions through to a display in their original form and at their original frequency, while retuning the display to receive the transmission at its original frequency. The television receiver may also receive, process and provide satellite or other types of programming to the television as necessary. The output of the receiver's modulator may switch back and forth as a user changes between local broadcast and satellite channels. Further, an EPG may be provided that includes information for both programming sources in an integrated fashion.

The microprocessor control unit receives power from a battery. An exemplary embodiment detects an operating voltage provided to the microprocessor control unit by a supplemental power reservoir after removal of the battery, stores information corresponding to a value of the operating voltage in a nonvolatile memory, repeats the detecting and the saving information as the operating voltage decays in response to a discharge of the supplemental power reservoir, and determines the actual minimum operating voltage for the microprocessor control unit based on a last one of the stored information corresponding to the value of the operating voltage. A learned critical voltage value is based upon the defined actual minimum operating voltage.

Abstract: Presented herein is a method of extending a recording in a media content receiver of a media event that is delayed. In the method, a recording of media content is begun at an expected start time for the media event based on a recording timer, wherein the recording timer indicates the expected start time and an expected end time for the media event. After beginning the recording, the media content being recorded is analyzed to determine an actual start time for the media event. The actual start time is then compared with the expected start time. If the difference between the actual start time and the expected start time exceeds some predetermined value, the expected end time is adjusted to extend the recording. The recording is then ended at the adjusted end time.

Abstract: Various mechanisms are described for indicating to a user a low battery condition of a remote control for a controlled device. More particularly, a remote control detects a low battery condition as well as the replacement of batteries in the remote control. The remote control transmits a low battery message to a controlled device responsive to detecting a low battery condition. The remote control refrains from transmitting one or more subsequent low battery messages to the controlled device prior to detection of replacement of batteries. The remote control transmits a battery status message to the controlled device responsive to detecting the replacement of batteries in the remote control. The controlled device utilizes the low battery message and the battery status message to determine whether to present a low battery indicator to a user regarding a low battery condition of the remote control.

Abstract: Described herein are techniques for determining a board parasitic capacitance of a crystal oscillator circuit. A crystal's frequency is measured under load condition off-circuit. After coupling the crystal to the oscillator circuit, external capacitors may be adjusted to produce frequencies approximating the off-circuit measurement with upper and lower margins. Calculation of the load capacitor values at the exact frequency measured off-circuit allows for derivation of the board parasitic capacitance by subtracting the calculated capacitor values from the original total load value used in the off-circuit measurement.
