Abstract: A communication system and method for transmitting and receiving signals is provided. The system and method include a source provider that provides image data, at least one transmitter, at least one satellite, and at least one receiver. The at least one transmitter transmits the image data obtained from the source provider. The at least one satellite is in communication with the at least one transmitter and receives and retransmits the image data. The at least one receiver is in communication with the at least one satellite, wherein the at least one receiver is adapted to receive the retransmitted image data, is mobile, and includes at least one antenna. The at least one antenna includes at least a first antenna that has a horizontal length of less than approximately twelve inches (12 in.).

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.

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 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 satellite tracking system includes a vehicle having an attitude measuring device for measuring an attitude of the vehicle. An antenna is mounted on the vehicle. An antenna pointing device is coupled to the antenna and points the antenna in a direction dependent upon the attitude measured by the attitude measuring device and a location of a satellite.
