Abstract: A heating pad for use with animals, or pet heating pad. The pet heating pad provides a pad with a cushioned exterior and a flexible but resilient interior that prevents overheating by maintaining or returning the pet heating pad to a flat profile. The pet heating pad heating system includes a heating element with temperature limitation controls for safe operation surrounded by layers of material selected for temperature control properties. The result is a pet heating pad that substantially reduces or eliminates the problems normally associated with heating pads such as hotspots, overheating, bunching, and folding while providing a pet with a physically and thermally comfortable surface upon which to rest.

Abstract: A portable animal containment device for confining an animal to a defined area. The portable animal containment device includes a flat and a correction unit. The flat is adapted to be portable and defines the area within which an animal is confined. The flat has an associated presence detector for detecting whether the animal is occupying the flat. When the presence detector indicates that the animal is not occupying the flat, a signal is transmitted to the correction unit by way of wireless communication. The correction unit is carried by the animal and administers a stimulus to the animal when the correction unit receives the signal from the transmitter. Consequently, when the animal moves beyond the boundary defined by the flat, it receives a stimulus, which encourages the animal to remain in the flat.

Abstract: A portable digital ultrasonic monitoring system and method for use by an operator in detecting the ultrasonic waves and temperature variations produced by sources such as leaks in pipes, arcing, electrical corona and machinery defects is provided. The digital ultrasonic monitoring system includes a microprocessor based system in a hand held elongate housing that digitally analyzes and stores information received from its sensors. The digital ultrasonic monitoring system provides a referenced decibel output reading of the signal strength of the received ultrasonic signals. In addition, a heterodyned type audio signal that is related to the sensed ultrasonic signals is provided to the operator through a pair of headphones. The portable device has user input keys that allow the operator to select from a variety of different operating modes. A display displays a variety of different readings depending upon the operating mode of the device.

Abstract: A highly portable infrared thermography system automates the collection, display, analysis, annotation, and recording of thermographic data and facilitates the efficient generation of reports. The system includes an infrared camera and a digital video data collector (VDC) having an embedded PC with an internal hard drive. The VDC also includes a VGA color LCD display with touch screen overlay for displaying images, presenting information to a thermographer, and for receiving data and command inputs from the thermographer. The system can be carried with a custom vest and battery belt, or it can be mounted to a hand truck. Thermographic images captured by the infrared camera are received by the VDC and displayed in real time at rates of at least thirty frames per second to eliminate flicker. The VDC also interfaces with a videotape recorder for displaying and recording images. Other interfaces include a visible image camera interface, a digital video interface, and a base station computer interface.
