Abstract: An optical module includes a diffractive optical element (DOE) with a transparent conductive trace disposed over a surface of the DOE. An emitter is configured to direct a beam of optical radiation through the DOE. Control circuitry is coupled to measure a resistance of the transparent conductive trace and to control operation of the emitter responsively to the resistance.

Abstract: An optical module includes an enclosure and an optical output assembly mounted on the enclosure. An emitter mounted in the enclosure is configured to emit a beam of light toward the optical output assembly. A connector, which includes two conductive layers separated by a dielectric layer, has a first side connected to the enclosure and a second side connected to the optical output assembly. An electrical trace disposed on the enclosure is connected to the first side of the connector so as to define a test circuit having a capacitance. Control circuitry is coupled to sense the capacitance of the test circuit, and configured to inhibit operation of the emitter upon sensing a change in the capacitance that exceeds a predetermined threshold.

Abstract: Systems disclosed herein are directed to a display stand unit for a retail environment. The display stand unit includes a base having an interior and a display stand. The display stand includes a stem that connects to and extends upwardly from the base and a receiving surface that is suspended above and spaced away from the base by the stem. The receiving surface is configured to releasably hold an electronic device above and spaced away from the base. The display stand unit further includes a security cable that extends out from the base. The security cable is configured to attach to the electronic device to movably secure the electronic device to the base. The display stand unit further includes a retractor disposed within the interior of the base and connected to the security cable. The retractor automatically retracts the security cable.
