20170290127 | LUMINANCE CONTROL APPARATUS AND LUMINANCE CONTROL METHOD - A luminance control device and a luminance control method for controlling luminance of a light emitting member are provided in order to reduce the amount of information to be stored while preventing the user from feeling uncomfortable. The CPU divides by the interpolation division number a value obtained subtracting the reference duty ratio from the reference duty ratio so as to calculate an interpolation variation width, and integrates the interpolation variation width to the reference duty ratio every time the interpolation period elapses, and the variation width in the luminance of the LED is therefore reduced, preventing users to feel uncomfortable, which allows for suppressing the amount of information to be stored. | 2017-10-05 |
20170290128 | INTELLIGENT SENSOR-ACTIVATED LIGHT CONTROL DEVICES, SYSTEMS, AND METHODS INCLUDING AMBIENT LIGHT SENSORS - An intelligent sensor-activated light control device including at least one ambient light sensor is described herein. In one exemplary, non-limiting embodiment, the motion is detected via one or more motion sensors. An ambient light level is then determined using one or more ambient light sensors, and a light control device causes light to be output at an output light level associated with the determined ambient light level. In one embodiment, the output light level is further determined based on a current time interval during with which the motion is detected. | 2017-10-05 |
20170290129 | Daylight Harvesting Light Fixture and Control System for Same - A daylight harvesting light fixture has a housing defining a light aperture, a light emitting diode (LED) in the housing for providing illumination through the aperture, a power supply for supplying drive current to the LED; a photosensor for sensing ambient illumination through the housing aperture, and a control circuit programmed and connected for a) turning off current to the LED for a dark interval imperceptible to the human eye; b) deriving an ambient illumination level signal based on the photosensor output while the LED is turned off; c) calculating an LED light output complementary to measured ambient illumination to achieve a target ambient illumination; and d) restoring drive current to the LED at a level adjusted to produce the calculated complementary LED light output. This sequence may be repeated periodically to maintain a target ambient illumination. | 2017-10-05 |
20170290130 | ILLUMINATING CONTROL SYSTEM AND METHOD FOR CONTROLLING ILLUMINATING DEVICE - An illuminating control system for controlling a plurality of illuminating devices is disclosed herein. The illuminating control system includes an image capturing device and a processor. The image capturing device is configured to capture images of an object. The processor is coupled to the image capturing device. The processor is configured to receive the images and determine whether the object is a predetermined object based on the images. If the processor determines that the object is the predetermined object, the processor controls the image capturing device to track the object to obtain a moving condition of the object. The processor turns on one of the illuminating devices correspondingly based on the moving condition of the object. | 2017-10-05 |
20170290131 | PROJECTION DEVICE - A projection device comprises a light source, a first attenuator and a second attenuator, a first driver, a second driver, a light receiving element, and a controller. The light source emits light. The first attenuator and the second attenuator attenuate intensity of the light from the light source. The first driver drives the first attenuator. The second driver drives the second attenuator. The light receiving element receives the light distributed by the second attenuator. The controller controls the second driver to control the distribution ratio of the light distributed to the light receiving element by the second attenuator according to control of transmissivity of light at the first attenuator by the first driver. | 2017-10-05 |
20170290132 | CONNECTED LIGHTING SYSTEM - Techniques are described for a lighting system in which light sources are controllable using signals sent over a wireless mesh network. During a commissioning process, a user interface (UI) may present a representation of nodes (e.g., light sources, sensors, controllers, etc.) that are broadcasting a wireless advertising signal. In response to a selection of a particular node, a wireless message may be sent to instruct the selected node to provide a visual indication of its presence, such as a flashing light. The visual indication may enable a user to discern the physical location of the node, such that each node may be added to the mesh network and, in some instances, to a group of nodes. The UI may also enable the definition of scenes, where each scene describes the brightness level or other operating characteristics of particular light source(s) and/or group(s) of light sources when the scene is active. | 2017-10-05 |
20170290133 | METHOD AND MEANS FOR REMOVING STATIC ELETRICITY FROM WATER - A water treatment device is provided to remove static or stray electricity from water. The device includes a pipe though which the water flows, with an electrical coil within the pipe. The coil captures or collects the electricity and transmits electricity to ground via a ground wire. | 2017-10-05 |
