    Abstract: Methods and apparatus relating to a photodiode-augmented infrared (IR) motion sensor are provided. The IR motion sensor can be used to sense mid-IR range radiation emitting from a person. Within the IR motion sensor, incident mid-IR range radiation impinges on an IR sensing element situated behind a Fresnel lens. Thus, when the person crosses a particular region in the range of the IR motion sensor, the IR sensing element detects a change in radiation signature, and can subsequently notify another system, such as a security system, of the change. The IR motion sensor also includes an ambient light-sensing element configured to provide information used to perform a quality check, such as to rule out “false positive” outputs, on information output from the IR sensing element.

    Abstract: Methods and apparatus relating to a pyroelectric IR (PIR) motion sensor are provided. The provided PIR motion sensor can be used to determine an angular position of a moving person relative to the PIR motion sensor. The provided PIR motion sensor can be used to determine a proximity of a moving person relative to the PIR motion sensor. The angular position and the proximity can be used to identify a false alarm, estimate occupancy of a region, enable tracking of a target, and the like. In an example, the provided PIR motion sensor includes multiple PIR sensors and a Fresnel lens including lenslets configured to direct received IR radiation to at least two of the PIR sensors.

The thermostat may also include a sensor mount assembly containing the proximity sensor, the temperature sensor, and a first alignment feature. The thermostat may additionally include a lens assembly having a first area, a second area, and a second alignment feature, where the second area includes a Fresnel lens, and the first area is thinner than the second area. The thermostat may further include a front cover where the outward-facing surface of the lens assembly is shaped to continuously conform to a curvature of the front cover. The thermostat may also include a frame member with third and fourth alignment features configured for respective matable alignment with the first and second alignment features and configured such that the proximity sensor and the temperature sensor are maintained in generally close, non-touching proximity to the lens assembly, the first area of the lens assembly being aligned with the proximity sensor, and the second area of the lens assembly being aligned with the temperature sensor.

    Abstract: Various arrangements for using multiple wavelengths of electromagnetic radiation to detect smoke by a smoke detector are present. Multiple modes of the smoke detector may be used in which a first wavelength of electromagnetic radiation is emitted into a smoke chamber while a second electromagnetic radiation emitter is disabled, a period of time is waited, and a second wavelength of electromagnetic radiation is emitted into the smoke chamber while the first emitter is disabled. Depending on the mode of the smoke detector, the period of wait time may be varied.

    Abstract: An apparatus for testing transmittance includes a sample unit to position a material under test. The material under test is disposed between respective flat surfaces of a first mount and a second mount, which are positioned in the sample unit for a test round. The sample unit defines a first volume and a second volume, wherein arc shapes, variously formed by respective surfaces of the first and second volume, conform to an imaginary circle. During the test round, a rotation unit successively changes an angular position of the MUT relative to a light source. A light detector receives light from the light source which has been transmitted through the first volume, the MUT and the second volume. Based on the received light, a transmittance signature of the MUT is determined for a range of incidence angles.
