A remote control system having a universal transmitter capable of being programmed to match the frequency and modulation pattern of any pulse modulated remote control transmitter. The system combines the universal transmitter and a separate apparatus for programming the universal transmitter. The programming unit detects the frequency and modulation pattern transmitted by a selected transmitter. The programming unit transfers the detected modulation pattern to the universal transmitter. The universal transmitter is operative to transmit the frequency detected by the programming unit. The universal transmitter thus duplicates the transmission of the selected transmitter. The system, apparatus and methods of this invention are particularly well adapted for application to low cost remote control transmitters permanently installed in vehicles.

A plurality of infrared controlled appliances are controlled from a single UHF radio transmitter remote controller. The controller provides a plurality of separate distinct output control signals to an UHF to infrared transponder. The transponder has a UHF receiver, an infrared receiver, and an infrared transmitter. In one mode of operation, the transponder stores a received infrared signal and correlates it with a received UHF signal. In the operational mode, the transponder transmits a stored infrared signal through the infrared transmitter upon receiving a correlated UHF signal.

A computerized antenna mount system for continuously tracking a satellite in geosynchronous orbit that has an inclined orbit with respect to the equator. An antenna mount that automatically adjusts the declination angle of a ground station satellite antenna as a function of time after iteratively compiling the declination angle history from one complete orbit of a satellite. Different satellite orbits may be so compiled with selection of each satellite and its corresponding orbit information from memory.

An apparatus for actuating and deactuating a brake light affixed to a motorcyclist's helmet without any interface to the motorcycle. The apparatus illuminates and extinguishes the light by sensing the acceleration and deceleration forces.

A method and apparatus for causing a plurality of navigational lanterns, each equipped with an independent light sensing device and connected to a common synchronizing terminal, to actuate simultaneously at dusk, and deactuate simultaneously at dawn. The light sensing device senses the three levels of day, twilight and night. When a sensing device senses day, the connected lantern is disabled from flashing and is disabled from sending a synchronizing signal to other lanterns to flash. When a sensing device senses twilight, the connected lantern is enabled to receive the synchronizing signal, but is disabled from sending a synchronizing signal. When the sensing device senses night, the connecting lantern is enabled and a synchronizing signal to flash is sent to all of the lanterns.

A water sampler for delivering simultaneous multiple samples in which the samples are taken and discharged by a plurality of glass chambered syringes driven by a crank with water flow being controlled by a glass chambered valve having a valve spool shifted under the control of the crank.
