Abstract: A pet location monitoring and deterrent system is provided. The system includes a first pet collar assembly that transmits a first RF signal. The system includes a first pillar assembly having a first control module, a first RF receiver module, an infrared photodetector array, a first wireless transceiver circuit, and a first warning light. The system includes a second pillar assembly having a second control module, a second RF receiver module, an infrared phototransmitter array, and a second wireless transceiver circuit. The first and second pillar assemblies are disposed a predetermined distance apart from one another such that a warning area is defined in front of and proximate to the first and second pillar assemblies and a keep-out area is defined behind and proximate to the first and second pillar assemblies.

Abstract: A method and system for monitoring and reporting vehicle tire pressure information. The system includes tire pressure monitors mounted to the tires of a vehicle. The tire pressure monitors detect tire pressure information from their respective tires and transmit that information to transponders that are fixedly-mounted to the vehicle. Each tire pressure monitor corresponds to a single transponder. When a tire pressure monitor transmits tire pressure information, the corresponding transponder receives the signal and transmits the tire pressure signal along with a unique transponder identification code to a vehicle central system controller. Based upon the transponder identification code, the central controller associates the tire pressure information with a particular tire location. However, under certain conditions, a transmitted tire pressure signal is received by one or more of the non-corresponding transponders as well as the corresponding transponder.

Abstract: A system for monitoring and tire pressure in vehicles and correlating the specific locations of the vehicle tires with the tire pressure data of each tire. The system includes a tire pressure monitor operatively connected to each tire. A plurality of transponders, each having a unique identification code, are fixed to the vehicle such that there is one transponder secured proximate to a predetermined tire. During operation, each tire pressure monitor transmits tire pressure data to its corresponding transponder. The transponder adds its unique location identification code to the tire pressure data and transmits the data to a central system receiver. The central system receiver selectively displays the tire pressure data by tire location.

Abstract: An improved digital communications system is disclosed in which synchronization information is transmitted with the data. A start pulse, having a duration different than the other pulses in the transmitted digital data signal is used to mark the beginning of the frame of digital data. Preferably, a midpoint pulse is also transmitted with the start pulse to mark the midpoint of the frame to facilitate the generation of a local clock signal. Bit positions within the transmitted signal are sampled by sampling pulses which are generated by digital timers having time intervals keyed to the start and midpoint pulses.

Abstract: A system is disclosed for transmitting a sensed temperature from a transmitter to a remote receiver over a modulated carrier through the atmosphere. The transmitter and the receiver are battery powered and include timing circuitry having low power consumption. The transmitter and the receiver are both cyclically turned on for a relatively short period and off for a relative long period with the receiver's on cycle being synchronized with the occurrence of the transmission of the modulated carrier. The receiver further employs techniques to minimize the effect of noise on the reception of the transmitted data which can occur from extraneous signal sources broadcasting in the same frequency band or from environmental noise.
