Abstract: An ultrasonic ground speed sensor has a single transducer which both transmits and receives ultrasonic signals. The sensor is mounted on a vehicle in alignment with the direction of the vehicle, the transducer having a built-in angle with the body of the sensor unit. The transmitted signal is clocked by a 16 MHz clock, with the signal received by the transducer selectively filtered and amplified. A temperature sensor is also used to determine the speed of the transmitted and received signal. A 64-cycle sample period is used, as well as multiple counters and a signal processor to increase accuracy and minimize erroneous readings. A drop-out detector and monitoring system sensor is also described. The vehicle speed is calculated from a Doppler-based formula as a function of both the sum and difference of the transmitted and received signal frequencies. Also disclosed is a gasket seal having leak holes for drainage from the interior of the sensor.

Abstract: A liquid sprayer has a tank for storing liquid, a boom supporting spraying nozzles, and a pump and liquid control system for supplying liquid under pressure to the spraying nozzle in a manner that maintains substantially uniform liquid dispensing density independent of variations in the ground speed of the sprayer. A ground speed sensor, a liquid pressure sensor, and a liquid flow meter sends signals to a controller to regulate a valve that controls the rate of flow of liquid to the spraying nozzles.

Abstract: A protected memory circuit for use with an electronic data system includes a memory element such as a shift register, and memory control or lock means to selectively control enablement of the memory element for read/write operations. A separate power supply which may be a charged capacitor is used to power the memory and memory lock circuits in case of a power interruption in the main system with which the memory is being used, so that volatile data can be stored for re-use by the main system after the main power is restored. The lock includes a counter and a gate for inhibiting clock pulses to the memory element until a predetermined number of control pulses have been received to initiate a read/write operation. At all other times the clock input is blocked or clamped to prevent spurious signals or power surge transients from altering the stored data.
