Abstract: An open cell detection system includes a battery management system. The battery management system includes a control unit that transmits an open cell detection signal, to enable a balance unit for a first time period and to disable it for a second time period, and to enable an under-voltage comparison unit and an over-voltage comparison unit for a third time period. The under-voltage comparison unit compares a voltage with a first open cell threshold and outputs a first comparison result in the third time period. The over-voltage comparison unit compares a voltage with a second open cell threshold and outputs a second comparison result in the third time period. A judging unit determines whether a connection between a first battery unit and the battery management system is inoperative based on the first and second comparison results.

Abstract: An abnormality diagnosis device performs determination for at least one of abnormality of an electric motor driven by an inverter driven at a predetermined operation frequency and abnormality of a motive power transmission mechanism which transmits motive power from the electric motor to a load, wherein spectrum peaks extracted through FFT analysis of detected current of the electric motor are analyzed, and frequencies of spectrum peaks due to noise of the inverter are acquired in advance using the operation frequency and the frequencies of sideband waves with respect to the operation frequency. In abnormality diagnosis, abnormality determination is performed after spectrum peaks due to noise of the inverter are extracted from spectrum peaks extracted through FFT analysis of detected current of the electric motor.

Abstract: A luminaire includes an enclosure, an air valve, and a chamber. The enclosure includes a sealed cover and light beam emitting components. The air valve is air coupled between the enclosure and the chamber. The chamber includes a drying agent and has an opening with a membrane completely covering the opening. The membrane passes air while reducing the passage of water droplets in the air. The air valve blocks air passage between the enclosure and the chamber when closed. A method for testing to determine adequate sealing of an enclosure of a luminaire includes closing an air valve to seal the enclosure from outside air, activating a heat-generating component, determining whether an air pressure in the enclosure increases by more than a threshold value, and sending a signal indicating a result of the determination. The method includes deactivating the heat-generating component and opening the air valve.
