Abstract: An antenna system electronically searches for a satellite signal by beginning at the current pointing angle of an antenna. The antenna system sweeps a tuner frequency of the receiver by electronically commanding the receiver to tune to different transponder frequencies. By scanning through transponder frequencies, the antenna system can locate a satellite signal without mechanical movement. As a result, the satellite signal can be acquired more quickly than in some conventional systems.

Abstract: A DBS system requires a clear view of the southern sky to operate without interruption. During line-of-sight satellite blockages, the audio content of DBS programs is lost. The present invention provides a technique in which a continuous media track (e.g., audio and/or video) is presented to the system user even though the satellite signal may be temporarily blocked. A first media track is received and stored in a buffer area. After a time delay, a second media track is received which is a copy of the first media track. When an interruption occurs in the second media track during playback, a receiver/decoder box is able to seamlessly stitch (or splice) in the first (buffered) media track to provide a continuous media track to the system user.

Abstract: A system and method are provided for alerting of an occupant endangered by being situated in a variable temperature setting. The system can be utilized within a motor vehicle, and occupants include an infant, a child, a person, and an animal or pet. In an aspect, when a security device receives a signal that an occupant sensor detects the presence of an occupant and a temperature sensor detects a predetermined temperature, both within a predetermined time period, then a security response is initiated. A security response can include triggering an audible alarm, flashing a light, lowering a window, unlocking a door, notifying an owner of the security device, and transmitting an emergency signal to an emergency system including telephone 911 and an emergency response company. The occupant sensor and the temperature sensor may be affixed to a key fob such that an antenna transmits to the security device.

Abstract: An apparatus for determining the identity of a first detected satellite and to determine a second scan position for a satellite of interest based in part on the identity of the first detected satellite is disclosed. In one example the identity of the first detected satellite may be determined based on a satellite beacon or identifier.
