A communication unit for attachment to a vehicle is provided. The communication unit may include a housing, a mount, a printed circuit board assembly (PCBA), and a thermal architecture. The housing may include an enclosure defined by a lens surface and a rear enclosure. The lens surface has an emblem, and the rear enclosure has a vent. The mount may be coupled to the housing and is configured to attach the communication unit to a portion of the vehicle. The PCBA is disposed within the housing and behind the lens surface. The PCBA may include a plurality of light emitting elements configured to illuminate the emblem of the communication unit. The thermal architecture is disposed between the PCBA and the rear enclosure. The thermal architecture is configured to dissipate heat generated by one or more of the PCBA or the plurality of light emitting elements.

Illuminated communication unit for a vehicle within a transportation network

An illuminated communication unit for a vehicle is provided. The communication unit may include an enclosure carrying components within a cavity that include a printed circuit board assembly (PCBA) and a heat sink. The PCBA may include a position sensor in communication with the vehicle and configured to detect a position of the vehicle, and a plurality of light emitting elements disposed adjacent to the position sensor and configured to generate a light output. The heat sink may be configured to dissipate heat caused by the plurality of light emitting elements generating the light output. The communication unit may include a diffuser lens that includes a lens surface having an emblem disposed thereon, the diffuser lens being configured to receive the light output generated by the plurality of light emitting elements and diffusely illuminate the emblem. The lens surface may be configured to widely disperse the light output.

A lateral flow chromatography test device is disclosed that includes a stopping mechanism which enables a user of the test device to stop reactions of a test by pushing the stopping mechanism downward to remove materials flowing along a test strip in the test device at a time instructed by the manufacturer or decided by the user. This stopping mechanism is adapted to freeze the test result at the stopping time so as to keep the test result as a permanent record. The invention enables qualitative tests to become quantitative or semi-quantitative tests.
