Abstract: The present invention provides a method and apparatus for determining the functional status of an electromagnetic valve having a solenoid and plunger including determining the electro-mechanical switching time of a valve based on characteristics of an electrical characteristic responsive to the solenoid; comparing the valve electro-mechanical switching time to a predetermined value; and generating a valve status signal dependant on the results of the comparison.

Abstract: A circuit board, which includes one or more sensors, is integrated in a fluid control device, such as a valve manifold and a base plate. The fluid control device selectively directs a fluid used to control pneumatic or hydraulic equipment. The sensors are used to measure physical characteristics of the fluid, such as flow rate, pressure, and temperature. A flow sensor includes a paddle and a support member. The paddle is disposed at least partially in an orifice and is displaced in response to fluid flow. The support member positions the paddle in the orifice and includes a plurality of strain gauges. The strain gauges are disposed on only one side of the support member and are mechanically stressed in response to the paddle being displaced by the fluid flow.

Abstract: To make available to the vehicle control systems more information on the forces and directions of the forces which act on the individual tires, in order to determine these forces, the displacements between the outer ring and inner ring in the wheel bearings are measured in a contactless fashion using ultrasound. Displacements are measured by one or more sets of an ultrasound transmitter and a receiver on the stationary ring and a reflection surface on the rotating ring for reflecting back the ultrasound energy. The measured time until the signal is received enables displacement to be determined. It is possible to use these displacements to calculate the forces acting from a knowledge of the spring characteristic of the wheel bearings.
