Abstract: A multi-mode control device is provided for controlling a load device. A high-power interface of the control device can be electrically coupled to a high-power module. An occupancy sensor can receive a first current from the high-power module via the high-power interface, and a trigger detection device can receive a second current that is less than the first current from a low-power module via a low-power interface. The processor can switch the control device from a high-power mode for powering the occupancy sensor to a low-power mode by causing a reduction in the current provided to the occupancy sensor and causing current to be provided to the trigger detection device. The trigger detection device can detect a trigger in the low-power mode. The processor can cause the control device to operate in the high-power mode based on the trigger's detection.

Abstract: In some aspects, a relay control device includes a processor and a timer. The processor is electrically connectable to a relay that controls current flow to a load device. The processor causes the relay to be actuated at a first point in time so that a current flows to the load device. The processor determines an actuation duration for the relay from a measurement of the load current that is obtained with a current sense component. The processor determines a frequency of an input voltage or current from the measured load current. The processor synchronizes the timer with this frequency and identifies a zero-crossing point for a second load current based on the synchronized timer. The processor subsequently causes the relay to be actuated at a time that is offset from the zero-crossing point by the actuation duration.

Abstract: A lighting control device can include a control module and a processing module. The control module can provide a driving signal. The driving signal can modify a control voltage on a control interface. The control voltage can control a controllable ballast or driver. The processing module can determine a duty cycle of the driving signal. The control module and the processing module can receive power via the control interface and a power supply on the control device.

Abstract: An example system for determining the actuation duration of a relay can include a relay, a current-sensing device, and a controller. The relay can have an actuation coil, and armature, and a first and second contact. The current-sensing device can measure a current through the actuation coil. The controller can actuate the relay. The controller can also receive from the current-sensing device a plurality of measurement values for the current through the actuation coil. The controller can determine an actuation duration based on a local minimum value for the plurality of measurement values. The actuation duration can correspond to a duration of a movement of an armature of the relay from the first contact of the relay to the second contact of the relay. An actuation delay of the relay can be calculated based on the zero-crossing time of an input voltage value and the actuation duration.

Abstract: A multi-mode control device is provided for controlling an external load device. The control device includes a high-power interface, a low-power interface, and a control module. The high-power interface can be electrically coupled to a high-power module providing current from an external power source to the load device. The low-power interface can be electrically coupled to a low-power module. The high-power interface can receive a first current from the high-power module. The low-power interface can receive a second current from the low-power module that is less than the first current. The low-power interface can prevent the first current from flowing to the low-power module. The control module, which is electrically coupled to the high-power interface and the low-power interface, can operate in a high-power mode for powering the control module using the first current and a low-power mode for powering the control module using the lower second current.

Abstract: Systems and methods for creating and previewing a lighting effect, such as displaying an array of colors across a number of lighting fixtures are provided. A user may specify some of the colors for the array, as well as relative positions of the colors. A lighting management system determines transitional or intermediary colors and assigns the colors specified by the user, as well as the intermediary colors to the lighting fixtures. The resulting lighting effect may be displayed in a preview bar. The colors and the order of the colors may be edited to obtain a desired lighting effect.
