Abstract: A high-precision pressure sensor with two or more pressure ranges is formed from multiple micro-electromechanical system (MEMS) pressure transducers mounted inside a housing and coupled to sense a pressurized fluid. The non-linear outputs of the MEMS pressure transducers are linearized by a corresponding number of processors, preferably DSPs, each processor being coupled to a corresponding MEMS pressure transducer and receiving the MEMS pressure transducer output signal there from. Each processor generates an applied pressure output signal, which is representative of a pressure applied to the MEMS pressure transducer, which is a linearized and digitized version of output signal from the MEMS pressure transducers. The data that is output from multiple processors, each of which outputs pressure data pertaining to a different range of pressures, is transmitted serially on a serial data bus.

Abstract: A snap-fit sensing apparatus (20) for use in automotive applications including a housing (22) having a pair of flexible arms (30), a top portion (24), and a bottom portion (26), the flexible arms (30) extending from the top portion (24) to the bottom portion (26), at least one of the flexible arms (30) comprises a locking flange (32). The sensing apparatus (20) also includes a retaining mechanism (40) fixedly connected with the top portion (24), the retaining mechanism (40) securing the sensing apparatus (20) in place. In one preferred embodiment, the sensing apparatus (20) further comprises a sensor (50) located within the housing (22) for sensing one of temperature and pressure. In one preferred embodiment, the flexible arms (30) are connected with the top portion (24) and the bottom portion (26).
