Patent number: 10602590Abstract: A transceiver in a lighting system may include a digital isolation component having multiple channels and an isolation barrier. The digital isolation component may accept an outbound digital signal or an inbound digital signal. On a first channel, the outbound signal may be modulated with a high-frequency signal, and provided across the isolation barrier to the non-isolated side. On the non-isolated side, a modified outbound signal may be generated based on the modulated high-frequency signal. On a second channel, the inbound signal may be modulated with a high-frequency signal that is provided across the isolation barrier to the isolated side. On the isolated side, a modified inbound signal may be generated based on the modulated high-frequency signal. The transceiver may include a voltage level comparator configured to adjust voltage levels of the signals, or an edge transition or duty cycle balancer configured to adjust edges of the signals.Type: GrantFiled: October 23, 2018Date of Patent: March 24, 2020Assignee: ABL IP HOLDING LLCInventors: Dalibor Zulim, Stefan-Cristian Rezeanu, Nathaniel Christopher Herwig

Patent number: 9907132Abstract: A lighting control system allows user control of the color features of controllable light fixtures. Controlled color features may include the color, color temperature, tint, or other qualities related to the color of the light. Control of the color features may be independent from control of the intensity of the light fixtures. The system may use light-emitting diode (LED) light fixtures, or fluorescent or incandescent light fixtures. The system may enable control of the color feature using a controllable driver/ballast and a dimmer control. The color feature may be adjusted along a color path of adjacent values in a suitable color space model.Type: GrantFiled: October 29, 2015Date of Patent: February 27, 2018Assignee: ABL IP Holding LLCInventors: Dalibor Zulim, Richard Lee Westrick, Jr.

Patent number: 9887053Abstract: 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.Type: GrantFiled: July 29, 2015Date of Patent: February 6, 2018Assignee: ABL IP Holding LLCInventors: Dalibor Zulim, Richard L.
