摘要:
A process for manufacturing an integratable capacitative pressure sensor includes the following steps, starting from a semiconductor substrate (1): application of a guard film (2), precipitation of a polycrystalline semiconductor film (4), doping the polycrystalline semiconductor film (4) and removal of the guard film (2) by etching; then insulating the semiconductor zone (7) from the semiconductor substrate (1), and applying an insulator film (8) on the insulated semiconductor zone (7). The pressure sensor product, which is compatible with CMOS circuits and has increased sensor accuracy, includes a semiconductor zone (7) insulated from the semiconductor substrate (1) and an insulator film (8) applied on the insulated semiconductor zone (7), the polycrystalline semiconductor film (4) being located on the insulator film (8) above the insulated semiconductor zone (7).

A pressure sensor apparatus includes a reception container for receiving a pressure sensor, the reception container having an opening on one side. Furthermore, the pressure sensor apparatus includes a protective membrane closing the opening, a pressure sensor arranged in the reception container, and a gel arranged between the pressure sensor and the protective membrane.
摘要:
A pressure sensor for detecting an effective pressure comprises a first pressure detection means for providing a first pressure measurement signal and a second pressure detection means for providing a second pressure measurement signal, wherein the first pressure measurement signal differs from the second pressure measurement signal, as well as an evaluation means for determining the effective pressure based on the first and the second pressure measurement signal. Thereby it is achieved that in a pressure measurement the measurement errors are reduced.

The invention relates to a sensor module in a flexible housing with integrated transmission means. A possible application of such a flexible sensor module would be the use as transponder-based tire pressure measuring system. Here, the complete module could be vulcanized into the tire, and the data could be transmitted by means of a standardized receiver unit. The transmission may herein be made by radio or inductively, for example.

摘要:
A recording arrangement receives reception information including program, picture and/or sound information in a receiving channel of a television program. A detector detects the received program information which characterizes the start and end times of the television programs. A recorder is adapted to record the picture and/or sound information on a record carrier from a recording start time till a recording end time. A recording controller which, when a user of the recording arrangement has defined the recording start time and the receiving channel for a recording, is adapted to propose the end determined by the detector as the recording end time for the recording of the television program that can be received in the receiving channel.
