Patent number: 12015946Abstract: A wireless device may receive packets according to a protocol, such as Bluetooth, and may rapidly react to receive an interfering RF packet instead of dropping the first RF packet and the interfering RF packet, to decrease message delay due to collisions in high device density environments. When a received signal strength indicator (RSSI) difference between the interfering RF packet and the first RF packet exceeds a threshold, the device may detect the interfering packet and resync a portion of its circuitry to lock on to and receive the interfering packet. The wireless receiver may detect the interfering RF packet by detecting one or more of: a specific resync byte sequence, an increase in RSSI, or a phase shift. Additionally, a wireless device may add the specific resync byte sequence to an RF packet of a standard protocol.Type: GrantFiled: December 13, 2021Date of Patent: June 18, 2024Assignee: Lutron Technology Company LLCInventors: Ankit Bhutani, Richard S. Camden, Galen E. Knode

Patent number: 12010780Abstract: A load control system may include control devices capable of being associated with each other at one or more locations for performing load control. Control devices may include control-source devices and/or control-target devices. A location beacon may be discovered and a unique identifier in the location beacon may be associated with a unique identifier of one or more control devices. Upon subsequent discovery of the location beacon, the associated load control devices may be controlled.

Publication number: 20230403736Abstract: Wireless devices may perform modified carrier sense multiple access (CSMA) techniques in order to increase reliability while maintaining a reasonable latency for communications. The wireless devices may perform listen-before-talk (LBT) techniques using an adaptive transmission threshold (e.g., an adaptive CSMA threshold). The transmission threshold may be compared to a measured signal strength magnitude to determine whether the frequency channel is quiet enough for transmission of a packet. The transmission threshold may be initially set to equal a minimum value. The wireless device may increase the transmission threshold after each instance of LBT failure to allow the wireless device to get progressively more likely to transmit the packet each time LBT fails.Type: ApplicationFiled: August 24, 2023Publication date: December 14, 2023Applicant: Lutron Technology Company LLCInventors: Ankit Bhutani, Richard S.

Publication number: 20230309209Abstract: A control module for a lighting fixture may include an input circuit (e.g., a wireless communication circuit) that may be susceptible to noise generating by a noise-generating source (e.g., a lighting control device in the lighting fixture). The control circuit may execute a self-test procedure to determine if the magnitude of the noise is acceptable or unacceptable for normal operation of the control module. During the self-test procedure, the control circuit may measure a noise level at a connection of the input circuit and determine if the noise level causes the self-test procedure to fail. The control circuit may control the lighting load to multiple intensities, measure noise levels of the output signal at each intensity, and process the noise levels to determine if the test has passed or failed. The control circuit may illuminate a visual indicator to provide an indication that the self-test procedure has failed.Type: ApplicationFiled: May 30, 2023Publication date: September 28, 2023Applicant: Lutron Technology Company LLCInventors: Richard S.
