Abstract:

This electronic noise detector is an instructional device for classroom teachers to use in achieving academic excellence in educating students. Academic excellence is, among other things, dependent upon good discipline in the classroom and excessive noise in a classroom is disruptive of good discipline. This invention provides the classroom teacher with a means of immediately controlling the noise level in any classroom with any arrangement of the students. It further provides a means for instructing students to accept responsibility for maintaining a level of noise to the classroom which is conducive to achieving academic excellence. Operation of the device is simple. The teacher places it any place in the classroom that may be desired and turns it on. The device is then in a monitoring mode. The teacher sets an adjustable gain control and predetermines a level of noise which will be unacceptable.

Abstract:

This data transmitting apparatus is illustrated in a system for the remote reading of water meters. It includes a passive transmitter operated by the meter, a receiver including a source of energy, and means for connecting the receiver and its energy source to the transmitter. The receiver includes electrical loading means enabling it to read a submerged meter. The receiver is compatible with one type of transmitter having 14 output wires and with another type having only three. The data, e. g. , a reading of a meter, is transmitted as binary data in a word of 16 characters, each comprising four bits. A pulse coding system is insensitive to noise, and includes a first bit detector for each character, and a final character detector for each word. The receiver detects open circuits in the transmitter and produces an error signal in response to such open circuits. The receiver and transmitter may be coupled through a manual connector.
