Abstract
An example device can include a circuit assembly, an infrared sensor coupled to the circuit assembly, a switch coupled to the circuit assembly, an infrared lens coupled to a resistive element to alter a state of the switch when the infrared lens alters a position of the resistive element, and a light pipe ring positioned around the infrared lens to allow visible light to pass between an exterior and interior portion of an enclosure.
Claims20
A device, comprising:
- a circuit assembly;
- an infrared sensor coupled to the circuit assembly;
- a switch coupled to the circuit assembly;
- an infrared lens coupled to a resistive element to alter a state of the switch when the infrared lens alters a position of the resistive element;
- and
- a light pipe ring positioned around the infrared lens to allow visible light to pass between an exterior and interior portion of an enclosure.
3 more elements
A system, comprising:
- an enclosure;
- a circuit assembly positioned within the enclosure;
- a resistive element switch coupled to the circuit assembly;
- an infrared lens coupled to the resistive element switch such that altering a position of the infrared lens activates or deactivates the resistive element switch;
- an infrared sensor coupled to the circuit assembly at a location between the circuit assembly and the infrared lens;
- and
- a light pipe ring coupled to a perimeter of the infrared lens to:
- allow visible light to enter the enclosure to be received by an ambient light sensor coupled to the circuit assembly;
- and
- allow visible light generated by a light source coupled to the circuit assembly to leave the enclosure.
7 more elements
A multifunction button, comprising:
- a Fresnel infrared lens coupled to a hinge on a first edge and coupled to a resistive element switch on a second edge;
- an infrared sensor coupled to a circuit assembly between the first edge and the second edge of the Fresnel infrared lens;
- a light pipe ring coupled to the first edge and the second edge of the Fresnel infrared lens to allow light in the visible spectrum to pass through an enclosure.
