  • Publication number: 20190094078
    Abstract: A sensor system for detecting events is provided. The sensor system includes a sensor and a read-out interface. The sensor includes a transducer and a memory device. The transducer detects an event and generates a sensor signal in response to the event. The memory device includes a floating-gate with a sensing interface coupled to the transducer. The sensing interface has an energy barrier that leaks electrons at a predetermined electron leakage rate through Fowler-Nordheim (F-N) tunneling. The sensor signal alters a geometry of the energy barrier to change the electron leakage rate. The read-out interface is communicatively coupled to the memory device and retrieves data stored on the memory device for analysis. The event and a timestamp of the event are identifiable from the stored data.

  • Patent number: 10119682
    Abstract: The invention provides a luminaire comprising an optical element configured to spread light uniformly across a full visible face of the luminaire. The optical element comprises a central region and an outer peripheral region, each configured to receive light emitted by a light source arrangement and to direct this light out through a respective region of the light exit area of the luminaire. The central region receives light through a central transmissive surface portion which partially bounds it across its top. A further reflective tapered portion of the central region acts to reflect light incident at either of its two opposing sides, and provides a mixing function both within the central region of the optical element and within an inner compartment of the luminaire which extends between the optical element and the housing.
