Abstract
Systems, devices, and methods including: a relay, the relay comprising: at least one contact; a reflector attached to at least one contact; a sensor, the sensor comprising: an emitter configured to emit a pulse; a detector configured to receive a portion of the emitted pulse; where the reflector may be configured to reflect at least a portion of the emitted pulse to be received by the detector when the at least one contact may be in at least one of: an open position and a closed position
Claims20
A system comprising:
- a relay, the relay comprising:
- at least one contact;
- a reflector attached to at least one contact;
- a sensor, the sensor comprising:
- an emitter configured to emit a pulse;
- a detector configured to receive a portion of the emitted pulse;
- wherein the reflector is configured to reflect at least a portion of the emitted pulse to be received by the detector when the at least one contact is in at least one of:
- an open position and a closed position.
5 more elements
A method comprising:
- attaching a reflector to a first contact of two contacts of a relay;
- creating a window proximate the attached reflector in a housing of the relay;
- and
- placing a sensor proximate the created window for detecting a state of the relay.
1 more element
A method comprising:
- emitting, by an emitter of a sensor, a pulse;
- and
- receiving at least a portion of the emitted pulse through a window in a housing of a relay;
- wherein at least a portion of the emitted pulse is reflected by a reflector attached to a contact of the relay and received by a detector of the sensor if the reflector is disposed proximate the window in the housing of the relay.
