Disclosed is an electrically addressable lighting assembly for providing different adjustable light distribution patterns. The light distributions can be pre-programmed or adjusted once installed in an environment by use of a controller or control device. The lighting assembly comprises at least one primary optical element such as a focusing lens or light guide, which can be backlit and/or edgelit, and light sources arranged in two or more independently addressed electrical channels. Each light source channel being both physically separated and electrically adjustable in order to control light input into the optical element and subsequently adjust the light distribution output of the lighting assembly, The lighting assembly can be used to provide a wide range of symmetric and asymmetric lighting distributions for direct or indirect lighting as well as focusing or defocusing a projected beam in a spotlight or downlight configuration, The lighting assembly is therefore useful in a wide range of typical indoor and outdoor lighting applications including downlighting, spotlighting, wall washing, cove lighting, retail lighting, warehouse lighting, It is also possible to produce useful tunable white or color related lighting effects wherein different color temperature variants of white or different colors, such as red, green or blue might have different lighting distributions.

A light head for a medical device support system. The light head includes first and second zones of light sources, an optical system, and a control system. The first and second zones of light sources emit respective first and second beams of light that form an illumination pattern having a pattern size at a region of interest. The optical system adjusts a beam spread of the second beam of light to change the pattern size of the illumination pattern from a first pattern size to a second pattern size. The control system varies power to the first and second zones of light sources in response to adjustment of the beam spread of the second beam of light to maintain a substantially constant magnitude of illuminance at the region of interest as the pattern size is changed from the first pattern size to the second pattern size.

A laser diode firing circuit for a light detection and ranging device is disclosed. The firing circuit includes a laser diode coupled in series to a transistor, such that current through the laser diode is controlled by the transistor. The laser diode is configured to emit a pulse of light in response to current flowing through the laser diode. The firing circuit includes a capacitor that is configured to charge via a charging path that includes an inductor and to discharge via a discharge path that includes the laser diode. The transistor controlling current through the laser diode can be a Gallium nitride field effect transistor.

A device control system includes a control request issuing unit for issuing a control request defining a position of a moving object and the device control according to operation of a user; a determination plan generation unit configured to, based on the control request, generating a condition; a determination unit for determining whether a condition of the control request related to the moving object is satisfied and issuing an identifier of the control request; at least one condition determination generated by the determination plan generation unit; an execution plan generation unit for generating a control execution unit configured to receive the identifier of the control request, identifying a device that is a control target according to a control rule defined in the control request, and transferring a control command according to a control procedure, and one or a plurality of control execution units generated by the execution plan generation unit.

A control system may include a direct-current (DC) power bus for charging internal energy storage elements in control devices of the control system. For example, the control devices may be motorized window treatments configured to adjust a position of a covering material to control the amount of daylight entering a space. The system may include a bus power supply that may generate a DC voltage on the DC power bus. For example, the DC power bus may extend from the bus power supply around the perimeter of a floor of the building and may be connected to all of the motorized window treatments on the floor (e.g., in a daisy-chain configuration). An over-power protection circuit may be configured to disconnect the bus power supply if a bus current exceeds a threshold for a period of time.

When a base film used in a flexible display panel is bonded to a resin member for fixing the base film that is curved, the base film has creases by an environmental change such as temperature due to difference in linear expansion coefficient before and after a thermal shock. A buffer plate that is thin enough to be bent is provided between the base film used in a flexible display panel and the resin member. With the use of heat dissipation effect and heat equalization effect of the buffer plate, a structure around the panel capable of resisting the environmental change can be provided.
