Patents by Inventor Theodore M. McClelland, III

Theodore M. McClelland, III has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4034292
    Abstract: An opto-electronic pulse initiator for producing meter data pulses from a meter having a rotating movement. A directionally oriented pattern containing at least two reflective surfaces is driven by the meter movement to sequentially activate first and second optical sensors. The sensors are activated in opposite sequences in response to opposite rotations of the meter movement. A solid state pulse initiating circuit is utilized and includes low power digital integrated circuit elements, including a clocked bistable logic circuit. The optical sensors are connected to the inputs of the bistable logic circuit to produce predetermined mutually opposite binary logic states at the outputs of the bistable circuit, with the logic states corresponding to a given direction of meter movement. Data pulse output channels are controlled by the bistable logic circuit to selectively produce meter data pulses for a predetermined direction of rotation of the meter movement.

  • Patent number: 3943498
    Abstract: A completely solid state photoelectric pulse initiator for electric utility meter telemetry and recording systems includes a low power CMOS digital integrated circuit (I.C.) flip-flop output circuit for directly generating output pulses in response to the rate of rotation of a meter movement. A pulse rate dividing circuit is provided by a presettable divide-by-N CMOS digital I.C. in one preferred form for electronically varying the ratio of the output pulses relative to the input pulses. A simplified data magnetic recording receiver circuit is capable of being supplied recorder drive current directly from the Q and Q logic outputs of the output flip-flop to produce non-return-to-zero (NRZ) data pulse recording.
