Inventor
The Schrader valve (also called American valve) is a type of pneumatic tire valve used on virtually every motor vehicle in the world today. The Schrader company, for which it was named, was founded in 1844 by August Schrader. The original Schrader valve design was invented in 1891, and patented in the United States in 1893.

Pressure sensor method and apparatus
ActiveUS7377177B1Easy to understandSolid-state devicesFluid pressure measurement by mechanical elementsContact pressureOn board
A pressure sensor apparatus and a method of forming the same. A substrate (e.g., PCB) can be provided that includes a top side and a bottom side. A pressure transducer can be directly bonded to the top side of the substrate, wherein the substrate comprises substrate walls forming a plated through-hole that allows for the passage of a sensed media to contact a back side of the pressure transducer. Thereafter, a metal carrier with an integral port is bonded to the bottom side of the substrate, thereby forming a chip-on-board pressure sensor in which the need for a plating or coating to allow adhesion between the pressure transducer and the metal carrier is eliminated. The pressure transducer may comprise, for example, silicon or silicon bonded to glass. The metal carrier can be provided with a feature that mates with a valve such as a Schrader valve.

Wireless pressure sensing Schrader valve
A wireless tire pressure sensing system based upon a Schrader valve design is provided. The system includes a valve body, a valve pin and a compression element for sealing engaging the valve body and the valve pin to maintain tire pressure. A pressure sensing device mounted within the valve body and connected to valve pin senses the pressure within the tire and provides its signal to the valve pin. The valve pin is adapted as a component of an antenna that transmits a wireless pressure signal to a remote receiver / transmitter mounted on the vehicle. The receiver / transmitter transmits a corresponding signal to a vehicle control system that generates a warning signal when the tire pressure is below a threshold safety value.

The de-header valve (12) is equipped with, among other things, a sliding blind (122) that is contained and capable of moving within an upper (34) and a lower (38) seat, wherein one of such seats is a floating dynamic, live loaded seat that is capable of automatic adjustment through one or more loading zones so as to seal the blind (122) between the upper (34) and lower (38) seats. The movement of the sliding blind (122) serves to open and close the de-header valve (12), wherein in a closed position, the de-header valve (12) is prepared to receive the resid byproduct feed from the refinery process used to manufacture coke (4). Once the drum (18) is full, the de-header valve (12) may be actuated (opened), wherein the coke (4) that has accumulated on the blind (106) is sheared by the upper (34) and lower (38) seats, thus de-heading the coke drum (18) and facilitating the removal of coke (4) using methods commonly known in the art.
