IPC: B60R21/017
Filed: 2002-05-23
Abstract: In an on-board control system, a body ECU (10) executes various control operations in response to the supply of power voltage from a battery (21). There is connected on the power line of the battery (21) a voltage holding circuit (11) which is formed of a capacitor so that the variation of battery voltage slows. A switch input circuit (15) samples the on/off states of external switches (22) periodically under control of a microcomputer (13). The microcomputer (13) determines a fall of battery voltage, causing the switch input circuit (15) to stop sampling of switch states. Stopping the circuit operation and thus reducing the battery load current slows the voltage fall at the occurrence of collision of vehicle, allowing adequate time to store collision data in a collision memory circuit (18).

Abstract: The present invention relates to a method for manufacturing an MEA including a layer system, the layer system together with a plastic film located above and below it being punched out by a heated and shaped punching tool. The film-coated layer system, which is welded together only at the outer edges, is further processed by heating and pressing the marginal zones in a subsequent operation, the plastic film softening or melting in the marginal zone and penetrating the marginal regions. Thus, the marginal region in the periphery of the layer system is sealed in a gas-tight manner within seconds. The film inside the marginal zones which is no longer needed or not heated is removed by suction.

Title: Method and apparatus for generating a signal having at least one desired output frequency utilizing a bank of vibrating micromechanical devices
Inventor: NGUYEN CLARK T C
IPC: H03H11/04
Filed: 2001-04-20
Abstract: Several MEMS-based methods and architectures which utilize vibrating micromechanical resonators in circuits to implement filtering, mixing, frequency reference and amplifying functions are provided. A method and apparatus are shown for generating a signal having at least one desired outp ut frequency such as LO frequency in an RF subsystem in response to a tuning voltage and without the need for a phase-locking circuit. One of the primary  benefits of the use of such architectures is a savings in power consumption by trading power for high selectivity (i.e., high Q). Consequently, the present  invention relies on the use of a large number of micromechanical links in SS I networks to implement signal processing functions with basically zero DC pow er consumption.

Abstract: Known percutaneous tracheostomy dilators are inserted over a cannula previously introduced into the trachea on a hollow metal needle. In the present invention, the dilator is of plastics with a narrow, flexible patient end portion, a tapering intermediate portion and a substantially rigid, wider rear portion. The dilator is inserted on a needle the tip of which projects from the patient end of the dilator when the needle hub abuts the rear end of the dilator so that the patient end of the assembly can be pushed into the trachea. The length of the patient end portion of the dilator is such that the tip of the needle is spaced from the posterior wall of the trachea when the tapered portion of the dilator abuts the surface of the skin. After insertion, the needle is replaced with a guidewire so that the dilator can be pushed in further to expand the opening.
