Publication number: 20240057242Abstract: A device may detect a power removal event, determine whether the power removal event is a local power removal event or a system power removal event, and perform state correction. For example, the device may receive an indication of a state change event turning on the lighting device. The indication may be received from a sensor. For example, the sensor may include a photosensing circuit (e.g., capable of detecting light emission from the lighting device) or the sensor may include a live voltage sensor (e.g., capable of detecting a change in current driven to the lighting device). The device may then determine whether the power removal event is a system power removal event or a local power removal event. If the device determines that the power removal event is a system power removal event, the device may perform state correction (e.g., setting the lighting device to its state prior to the power removal event).Type: ApplicationFiled: October 25, 2023Publication date: February 15, 2024Applicant: Lutron Technology Company LLCInventors: Ankit Bhutani, Matthew Knauss, Timothy Mann, Michael W.

Publication number: 20230403777Abstract: A remote control device for controlling lighting devices may be configured to detect an excessive user interaction (e.g., a continued user interaction) and reduce a number of command messages that are being transmitted to prevent the lighting devices from producing undesirable visual effects. The remote control device may comprise a user interface (e.g., that may include a rotation portion, such as a rotary knob) and a processor configured to receive an indication of a user interaction via the user interface. The processor may periodically transmit command messages at a transmission frequency in response to a continued user interaction, where each of the command messages comprise a respective command for adjusting to a respective lighting level. The processor may also start a usage timer in response to receiving the indication of the user interaction, and decrease the transmission frequency in response to the usage timer exceeding a usage threshold.Type: ApplicationFiled: August 25, 2023Publication date: December 14, 2023Applicant: Lutron Technology Company LLCInventors: Matthew Knauss, Michael W.
