Abstract: An assembly for an ATIS that includes a tire inflation valve and a tire deflation valve, and further includes a safety valve that is configured to receive the tire pressure, deflate a tire when tire pressure is too high such as due to braking heat, road friction, ambient temperature, or other reasons. The safety valve prevents deflation of the tire through the deflation valve in the case of low source pressure, such as the pressure source fails or a leak in the source pressure system lines. The assembly is designed to be quickly serviced in the field, where the serviceable parts are very inexpensive. Multiple devices can be installed in parallel with the others, with one device per tire or tire set. The assembly can be a block configured to be attached to a hub cap of a vehicle. It also enables a sensor placement on the hub cap for hub temperature sensing as well as tire pressures sensing and reporting.

Abstract: An assembly for an ATI comprising a tube member forming a portion of a rotary union to be removed through an opening in a wheel hub without removing the wheel hub from the vehicle axle. The tube member may include a hardened shaft that is coupled to a fixed conduit providing a pressurized air source to a tire installed on the wheel hub. A bushing and seal rotates with respect to the tube member to form the rotary union. The assembly is designed to be quickly serviced in the field, where the serviceable parts are very inexpensive.

Abstract: A rotatable wireless electrical coupler is disclosed that presents a wireless alternative to mechanical slip rings, such as are used in rotatable mechanical assemblies such as dome cameras. The rotatable wireless electrical coupler is designed to provide for the wireless transfer therethrough of electrical power, video and data signals. A rotatable multi-function transformer of the electrical coupler is designed primarily for the transfer of electrical power therethrough, and can also be used for the transfer of data signals. A rotatable electrical capacitor of the electrical coupler is designed primarily for the transfer of video data signals therethrough, and can also be used for the transfer of control and feedback data signals. In a dome camera, the rotatable wireless electrical coupler transfers power and data signals to and from a rotatable platform/section on which is mounted a video camera, pan and tilt motors and other associated electrical components.

Abstract: A grinding wheel system includes a grinding wheel with at least one embedded sensor. The system also includes an adapter disk containing electronics that process signals produced by each embedded sensor and that transmits sensor information to a data processing platform for further processing of the transmitted information.

Abstract: System and method for measuring static load by using a piezoelectric load sensor with a feedback technique to compensate for the signal loss due to charge leakage, and therefore ensures measurement accuracy. The system is integrated with other structure, objects and devices to measure static loads applied to a mechanical shaft, in an on-line, in-process, quasi real-time fashion. The system can be used to measure static load and thus oversee an entire machine system or a manufacturing process.
