  • Publication number: 20220266810
    Abstract: A sensor assembly includes a fastener body extending from a fastener end to an opposite sensor end along an elongation direction. The sensor end is shaped to be inserted into a sensor port of an air dryer. A sensor substrate includes one or more conductive bodies protruding from the sensor substrate and one or more first conductive pathways coupled with the one or more conductive bodies. The sensor assembly also includes a sensor coupled with the sensor substrate and conductively coupled with the one or more conductive bodies by the one or more first conductive pathways. The sensor is configured to sense a humidity of air flowing through the air dryer. The one or more conductive bodies of the sensor substrate are positioned to engage one or more arcuate or annular conductive pathways in the air dryer in different rotational positions of the fastener body relative to the air dryer.

  • Patent number: 5744725
    Abstract: A capacitive pressure sensor and method of fabricating the sensor includes providing a layered structure including a second silicon layer (115), a second insulating layer (203, 205) in contact with the second silicon layer (115), a first silicon layer (123) in contact with the second insulating layer (203, 205), a first insulating layer (201) in contact with the first silicon layer (123), and a mask layer (221) in contact with the first insulating layer (201). A major exposed surface (220) of the second silicon layer (115) is provided by mechanically reducing a thickness (210) of the second silicon layer (115) to a predetermined thickness (116). Preferably this is done by grinding and then polishing the second silicon layer (115). In one embodiment a third insulating layer (211) is in contact with the second major surface (220) of the second silicon layer (115).

  • Patent number: 5444289
    Abstract: A method is provided for making a power device (54) and a small signal device (52) on a bonded silicon substrate (41). A first silicon substrate (10) provided. A first surface (17) is etched to form a plurality of cavities (11) with a depth (13). A dielectric layer (14) is created on the first surface (17), wherein the dielectric layer (14) is created with a thickness less than or equal to the depth of the plurality of cavities. The dielectric layer (14) is patterned so that a plurality of islands (22) of dielectric remain in the cavities. A second silicon substrate (42) is provided. The first and the second silicon substrates (10, 42) are bonded together in such a manner that the islands (22) are buried. A predetermined portion of the first silicon substrate (10) is removed, thereby creating a surface that is suitable for semiconductor device fabrication.

  • Patent number: 4199610
    Abstract: In the preparation of a dry, stable, phosphoric acid acidulated beverage mix, heretofore, a phosphoric acid chemical stabilizer was required due to the notorious hygroscopicity of H.sub.3 PO.sub.4, particularly in fructose sweetened systems. This invention eliminates the need for such stabilizers via the employment of pulverized crystalline sugar for improved structural stability, faster solubility and non-hygroscopicity of the dry beverage mix heretofore unknown in the art. The dry beverage mix of the present invention rapidly dissolves in aqueous solution which may be carbonated to form colas, root beers, sarsaparillas or any other beverage which contains phosphoric acid as a flavoring ingredient and acidulent. This dry beverage mix is made via vacuum drying a uniform slurry of the pulverized sugar, liquid flavorant and phosphoric acid acidulent.
