Patent number: 11258284Abstract: Techniques are presented herein to operate a light fixture as in an emergency mode in order to verify that the light emitted by the light fixture when operated in the emergency mode complies with emergency operating policies, as well as to detect failures. The light emitted by the light fixture in emergency mode may be measured and adjusted to optimize the runtime of the light fixture in the emergency mode. The light fixture is connected to a lighting control system via a control network which supplies electrical power to charge an onboard battery of a light fixture and to operate the light fixture. The light fixture may be caused to operate in the emergency lighting mode when a main electrical power supply is interrupted or when performances of the light fixture and of the onboard battery are tested.Type: GrantFiled: October 3, 2018Date of Patent: February 22, 2022Assignee: CISCO TECHNOLOGY, INC.Inventors: Matthew A. Laherty, William MacGowan, Charles Calvin Byers

Patent number: 9699858Abstract: Techniques presented herein are directed to the coordinated network-based control of the color capabilities of multi-color fixtures. A network device is connected to multi-color light fixtures each comprising a local processor and a plurality of color light emitters. The network device receives data inputs from one or more data sources and uses the data inputs to identify a color informational display for presentation across a plurality of the multi-color light fixtures. The network device generates messages encoding light control settings for each of the plurality of multi-color light fixtures enabling each multi-color light fixture to present a spatial or temporal segment of the color informational display and sends the messages to the plurality of light fixtures. Execution of instructions embedded in the messages by the local processors results in the creation of the color informational display across the plurality of multi-color light fixtures.Type: GrantFiled: December 8, 2014Date of Patent: July 4, 2017Assignee: Cisco Technology, Inc.Inventors: Matthew A. Laherty, Donald Schriner, William MacGowan, Charles Calvin Byers

Patent number: 9596739Abstract: A lighting control system is provided which accepts user lightning commands, generates controls in accordance with predetermined operating policies and directs light fixtures to produce brightness, color, or directional pattern of the light emitted by the light fixtures. The lighting control system determines whether the light emitted by the light fixtures complies with government regulations, and building policies, and insures that controls are adjusted such that all regulations regarding lighting safety and working conditions, as well as building policy and energy management targets are adhered to. In addition, a way to reconcile conflicting user requests for lighting settings is provided.Type: GrantFiled: July 31, 2014Date of Patent: March 14, 2017Assignee: Cisco Technology, Inc.Inventors: Matthew A. Laherty, John D. Parello, William MacGowan, Charles Calvin Byers, Xiaohang Li, Luis O. Suau, Donald Schriner
