Abstract: In an example, a method comprises communicating with a radio frequency (RF)-enabled asset tag within a space, tracking a location of the RF-enabled asset tag within the space, determining location estimates of the asset tag as the asset tag moves within the space, and accepting identifying information from or about a selected user. The method additionally comprises determining, based on a predetermined correspondence criteria, a correspondence between the asset tag location and a position estimate of an electronic hardware device within the space. Further, in response to determining the correspondence between the asset tag and the electronic hardware device and based at least in part on the identifying information accepted via the electronic hardware device, the method includes associating tracked asset tag location information corresponding to the location estimates of the asset tag as the asset tag moved within the space to identification of the selected user.

Abstract: A lighting control system includes a daylight sensor configured to receive visible light control signals to set or adjust one or more parameters of the daylight sensor including, e.g., a set point (i.e., an acceptable lighting level). The lighting control system also includes a non-transitory computer program product that includes programming instructions that may be downloaded to, e.g., a mobile device and/or may be executed by a processor or like device. The programming instructions may be configured to provide a user interface related to the daylight sensor, receive via the user interface one or more user inputs related to the daylight sensor, and modulate a light output of a light source to transmit visible light control signals corresponding to the received one or more user inputs. Methods of programming a daylight sensor with visible light control signals are also provided, as are other aspects.

Abstract: A daylighting device includes a photo-voltaic (PV) device that is mounted in or proximate to the daylighting device that provides sunlight to a service area. The PV device generates a power signal from incident sunlight. The power signal provides operational power to circuitry associated with the daylighting device, such as a transmitter that transmits a value representing the intensity of light on or near the daylighting device. This signal, which is generated either from the power signal or from a signal provided by a photosensor mounted in or proximate to the daylighting device, may be used by a control system to adjust light levels provided by artificial light sources to supplement the sunlight provided by the daylighting device to approach the desired light level in the service area.

Abstract: A lighting system distinguishes between light from natural and manmade sources to prevent the system's light source from being inadvertently deactivated due to light received from manmade light sources. A sensor converts received light into electrical energy. The system light source and/or some other external light source can emit light with a modulation. The system includes a modulation detector that can detect the modulation in the electrical energy received from the sensor. A system controller selectively adjusts the flow of electrical energy to the system light source responsive to the electrical signals from the sensor. The controller adjusts the flow of electrical energy in response to the non-modulated component of the electrical signals from the sensor. The controller does not adjust the flow of electrical energy in response to the modulated component of the electrical signals from the sensor.

Abstract: A method of determining a setpoint of a load control device for controlling the amount of power delivered to an electrical load located in a space, the method comprising the steps of initially setting the value of the setpoint equal to a desired level; limiting the value of the setpoint to an occupied high-end trim if the space is occupied; limiting the value of the setpoint to a daylighting high-end trim determined by a daylighting procedure; and subsequently reducing the value of the setpoint in response to a load shed parameter.
