Abstract: A projection system includes a recessed projection fixture that includes a lighting module configured to emit a light and a projection module configured to project an image. The light emitted by the lighting module is used for projecting the image and for illumination. The projection system further includes a sensor, where the projection module projects the image in response to an occupancy detection by the sensor. The recessed projection fixture is oriented to direct the image toward a surface below the recessed projection fixture.

Abstract: A trim for a lighting fixture includes a trim structure, a processor disposed on the trim structure, and an interface electrically coupled to the processor. A power is provided to the processor from a power source of the lighting fixture via the interface.

Abstract: A projection fixture includes a lighting module that emits a light, and a projection module that projects an image. The projection fixture further includes a controller that controls operations of the lighting module and the projector module, where the light emitted by the lighting module is used for projecting the image and for illumination.

Abstract: A system of projection fixtures includes a first projection fixture recessed in a ceiling, where the first projection fixture includes a first projector device. The system further includes a second projection fixture recessed in the ceiling, where the second projection fixture includes a second projector device. The first projector device is positioned to project a first image on a first surface below the ceiling, and the second and projector device is positioned to project a second image on a second surface below the ceiling.

Abstract: A lighting fixture includes a light emitting diode (LED) light source, a clock module, and a controller configured to control one or more characteristics of a light emitted by the LED light source based on time information received from the clock module. The controller is further configured to determine a current time of a day from the time information received from the clock module.

Abstract: A method of customer interaction includes receiving, by a management system, reservation information of a customer for a business location. The method further includes receiving, by the management system, a first message indicating an arrival of the customer at the business location. The first message is received by the management system from a lighting fixture that received the first message from a mobile device via a visible light transmission. The lighting fixture is located at the business location. The method also includes transmitting, by the management system, a second message to the mobile device in response to receiving the first message.

Abstract: This invention relates to selenium rectifiers and a method of making them. Using techniques of electrophoretic deposition of selenium, a selenium rectifier is manufactured having a barrier layer adjacent the base electrode. This results in a cheaper rectifier with improved heat dissipation.
