Dental hygiene and periodontal hand instrumentation requires alignment of the cutting surface of the instrument at a specific angle and adaptation to the tooth surface. A dental hygiene and periodontal hand instrumentation tutor provides an objective, consistent and accurate way to measure and display the actual angulation and adaptation angles of a periodontal hand instrument and assess instrument use continuously. The method includes detecting the position, orientation, motion path, pressure, angulation angle, adaptation angle, and centerline angle of a periodontal hand instrument and comparing them to ideal positions, orientations, and motion paths; and provides various forms of user feedback.

An ultrasonic bin level control circuit which employs a fail-safe circuit to shut off a compressor when echoes are late or absent, and a transducer mounting system which facilitates installation and removal of a transducer for servicing and cleaning. A level detector compares a reference signal with a reflected signal, the ice reaching a desired level when the reflected signal overlaps the reference signal. When the desired level is reached, the reference signal is modified through feedback to prevent short cycling of the compressor. The transducer is installed within a cylindrical housing which is easily installed and removed from a cylindrical socket within a compartment above the bin.

A toy bank having a coin discriminating mechanism for discriminating between coins of varying diameters. The mechanism includes a housing having a coin slot, the slot having two generally flat, spaced walls and two relatively narrow spaced sides, the sides defining the breadth of a coin passageway. A movable slide is disposed within the passageway and normally biased toward a resting position at least partially obstructing the breadth of the passageway. The slide is movable in response to insertion of a coin. Electronic circuitry is provided to detect movement of the slide and translate that movement into information relating to the denomination of the coin. Preferably the slide is movable in a direction not parallel to a line defined by a first point of contact between a coin and the slide, and a second point of contact between the coin and the first side of the passageway, said points of contact being identified when the slide is maximally displaced by the coin. In this configuration, the differences in displacement of the slide upon insertion of coins of varying diameters will be larger than the differences in the diameters of the respective coins.

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.

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.

Input channels are provided for receiving data pulses from sensors or other parts of an electronic data system. Filters, for examle r-f decoupling filters, are provided for each channel prior to passing the pulses to a utilization device, such as a counter or the like. The shunt or grounding capacitors of the filters are tied together and connected to the output of a test pulse generator which performs two functions. In normal operation, the output circuit of the test pulse generator provides an effective AC path to ground for normal operation of the filters and their shunt capacitors. In a self-test mode, the test pulse generator provides a test pulse which is coupled through the shunt capacitors, the filters and optional wave shaping amplifiers to the utilization device for verification of the operative condition of the circuits.
