Title: Ultrasonic data transmission method via machine part, pipe - combining transmission with security steps to increase reliability
Inventor: KINDERLING ECKART
IPC: G08C23/02
Filed: 1991-08-09
Abstract: The transmission method uses a known pulse-interval modulation. For the increase of the transmission reliability, a number of further measures are combined. For this purpose the transmit frequency, the transmit rate, and the quartz frequency of a microprocessor are precisely matched. In the transmission, a high signal is represented by a pulse while a low singal is represented by a pulse absence, with the interval time constant. Pref. several ultrasonic pulses are used for representing a high signal. The intervals are used for transmission of a repeater signal of the same frequency during this time period. USE/ADVANTAGE - For ultrasonic data transmission via machine parts, pupes, supports etc, with high reliability and at high data rate.

Title: Measuring level of liquid in housing, esp. of oil in vehicle engine - evaluating voltage across metal resistive element immersed in liquid and in series with current generator
Inventor: DELAPORTE FRANCIS
IPC: G01F23/24
Filed: 1992-09-23
