Patent ES-8501102-A1 (ES)
Title: Device for the perception of gas flow
IPC: G01F3/22
Filed: 1984-02-16
Abstract: This device is to be installed between the origin of a gas supply and a gas supply pipe on a gas utilizing tool. As a diaphragm moves up, due to the difference in atmospheric pressure inside a chamber of the device, a first magnet positioned on an elastic plate is moved up by the magnetic forces of mutual attraction from second magnets secured to a plate on the diaphragm. The first magnet is subject to moving out of the magnetic attraction force area by the repulsion of the magnets and the force of restitution of the elastic plate. The supply of gas is dependent on the opening of a valve mounted on the elastic plate. As the first magnet moves away from the plate on the diaphragm, the magnetic forces of the first magnet move a lead-switch to the "ON" state to indicate gas is flowing. In case of a large leakage of gas at the gas utilizing tool side of the device, the atmospheric pressure of the upper portion of the chamber is reduced, and the increased atmospheric pressure inside the lower portion of the chamber rapidly forces the diaphragm up and pulls up. A crosspiece of a U frame mounted on the plate on the diaphragm lifts the elastic plate and the valve to cause the shutting "OFF" of the supply of gas.

Title: Vehicle multiplex system having protocol/format for secure communication transactions.
IPC: B60R16/03
Filed: 1984-02-23
Abstract: An improved serial data protocol/format is provided in a serial multiplex system for use in an automotive vehicle electrical system which is subject to electrical noise. The protocol/format includes successive transactions between a master controller and respective remote controllers each connected to a serial multiplex bus. Each transaction is bidirectional and includes a command message transmitted by the master controller and a reply message normally transmitted by an answering remote controller. Each command message is preceded by a multibit SYNC byte. The command message includes an address byte (for a particular remote controller), a command byte, and an error check such as a cyclic redundance check byte passed on the address and command bytes. The reply message includes the address byte of the replying remote controller, a response byte indicative of its response to the command byte, and an error check such as a cyclic redundancy check byte based on the reply address and response bytes. The master controller may be caused to repeat the transmission of a command message if the address bytes, the command/response correlations or error check bytes are not verifiable, thereby enhancing the system's ability to detect and/or reject errors as might be occasioned by noise.
