Abstract: A method and associated apparatus directed to a piezoelectric micromachined ultrasonic transducer (pMUT) defining an air-backed cavity are provided. A first via defined by a device substrate and associated dielectric layer, and extending to the first electrode, is substantially filled with a first conductive material. A support member engaged with the device substrate defines a second via extending to the first conductive material. The second via has a second conductive material disposed thereon, forms an electrically-conductive engagement with the first conductive material, and extends outwardly of the second via to be accessible externally to the support member.

Abstract: The disclosure generally relates to a method for remote reading the tamper-proof storage of the odometer reading in a vehicle by, for example, making available an alternative wireless method for the accessing of odometer reading data. In one embodiment, the disclosure relates to a method for remotely reading odometer data in a vehicle having control units which are connected via a data bus. The odometer reading data, which is determined at a particular time by an odometer, can be stored in a storage means of a first control unit, thereby providing an alternative method for remotely accessing odometer reading data and, in particular, improved protection against errors during the transmission of the odometer reading data. The current odometer reading data of at least one further control unit is then stored on the data bus in a storage means.

Abstract: According to one embodiment, the disclosure relates to a system adapted for, among others, interfacing with a control network of a vehicle, said system comprising a program for monitoring data available in said control network and adapted to send selected data to a data link of said vehicle; a processor for receiving said selected data from said data link and decoding said selected data into decoded data available for subsequent use.
