Disclosed are garage door sensor systems and devices that include one or more transmitter sources configured to transmit an electromagnetic (EM) waveform and one or more receiver circuits configured to receive the electromagnetic waveform from the transmitter source. The receiver circuit is configured to determine an active duration of the received electromagnetic waveform in a predetermined detection time window. The receiver circuit is configured to send a blocked beam signal based on the determined active duration and the predetermined detection time window. The blocked beam signal indicates to the garage door motor assembly that an obstruction is in the signal path between the transmitter source and a receiver sensor of the receiver circuit.

Safety sensors

Disclosed are systems comprising: a transmitter background; a receiver background; a plurality of transmitter units affixed on the transmitter background, each transmitting an encoded electromagnetic wave (EM), wherein the electromagnetic wave is transmitted as a wide beam; and a plurality of receiver units affixed on the receiver background, wherein each of the plurality of the transmitter units is in electromagnetic communication with at least one of the receiver units. Also disclosed are methods of identifying the presence of an object intersecting a spatial surface. Further, a housing for the system is disclosed.
