Abstract: An actuator apparatus includes a pair of substrates facing each other; a plurality of bias actuators that each vary a gap dimension of a gap between the pair of substrates; a gap detection portion that detects the gap dimension; and a voltage control unit that controls driving of each of the bias actuators on the basis of the detected gap dimension. The bias actuators are located asymmetric relative to a driving central axis and are mutually independently driven; and the voltage control unit derives driving parameters for use in driving the bias actuators, on the basis of voltages and gap dimensions obtained by sequentially switching and driving the bias actuators on by one.

Abstract: A system for transporting high luminous intensity light from at least one luminaire to a destination area is disclosed. The system may include a light guide that carries light from the luminaire to a plurality of sensors located on a Printed Circuit Board (PCB). The PCB may be attachable anywhere the luminaire is located. While collecting light rays originating from the luminaire and delivering them to the light sensors, the light guide may perform a plurality of operations to modify the characteristics of the collected light rays. The plurality of operations performed by the light guide on the light rays may support the accuracy and longevity of the light sensors on the PCB. Further, the light guide allows the sensor subsystem to be proximal to or distant from the luminaire.

Abstract: The present system provides a sensor clip system that can be clipped to luminaires of a plurality of shapes and sizes and method of using the sensor clip. Some of the sensors are upward looking (into the luminaire) while others are downward looking (away from the luminaire); and thus face in substantially opposite directions. The sensor clip is adjustable in one, two or three dimensions to be able to easily fit with different sized and shaped luminaires, such that the upward looking sensors may face the incoming light and downward looking sensors face away from the light. The sensor clip system may also provide attenuation of the luminous intensity of the emitted light coming out of the luminaires and extends the longevity and usability of the embedded sensor.

Abstract: In an example, a method of gamut mapping may include generating a plurality of color values in a first color space based on a plurality of measured color values in a second color space using a color specification that maps color values corresponding to the second color space to color values corresponding to the first color space. The method may include generating a second-order or higher response-surface regression model that maps color values corresponding to the first color space to color values corresponding to the first color space.
