Patent number: 10932343Abstract: A protection system and operating method thereof promotes the longevity of components of a control subsystem. The protection apparatus may include a first connector for connecting to the control system and a second connector for connecting to a target system. The protection apparatus detects states of a component of the control subsystem over time and causes a state transition of a switching circuit of the protection apparatus based on the detected states of the control subsystem. The state transition of the switching circuit of the protection system may be initiated after a defined period of time has elapsed after detecting states of the control subsystem component. The state transition of the switching circuit may be a transition between an open state in which power is not provided to a node of the second connector and a closed state in which power is provided to the node of the second connector.Type: GrantFiled: May 10, 2019Date of Patent: February 23, 2021Assignee: EXPRESS IMAGING SYSTEMS, LLCInventors: William G. Reed, Dale H. DeGraff, Richard Dolf, Donald Arthur Vendetti

Patent number: 9801248Abstract: An illumination system verifies whether one or more aspects of an output signal provided by a photosensitive transducer fall within a threshold of an expected value for the aspect. The aspect may include a sunrise time, a sunset time, a dawn time, a dusk time, a solar noon time, a solar midnight time, or similar. Upon verification the illumination system uses a microcontroller to adjust one or more output parameters of a solid-state light source responsive to the output signal provided by the photosensitive transducer. Where verification is not possible, the illumination system uses the microcontroller to adjust one or more output parameters of the solid-state light source responsive to a schedule.Type: GrantFiled: August 3, 2015Date of Patent: October 24, 2017Assignee: Express Imaging Systems, LLCInventors: William G. Reed, Dale H. DeGraff, Richard Dolf

Patent number: 9693433Abstract: An illumination system verifies controls the operation of a luminaire without the use of any photometric data. The illumination system uses data indicative of a current time, date or latitude to determine one or more aspects of a solar event. Such aspects can include a scheduled, predicted or expected time of occurrence of the scheduled solar event. Responsive to the determination of a scheduled, predicted or expected time of occurrence of the scheduled solar event, a control subsystem can adjust the luminous output of a light source.Type: GrantFiled: November 24, 2014Date of Patent: June 27, 2017Assignee: Express Imaging Systems, LLCInventors: William G.

Patent number: 9497393Abstract: An illumination system and methods to control a light source are provided. An illumination system includes a light source, a two-dimensional non-Passive Infrared (non-PIR) imager, and a controller. The light source may provide at least two levels of illumination. The non-PIR imager images an area and to produce image data representative of images across at least part of a visible portion of an electromagnetic spectrum. The controller is communicatively coupled to receive the image data from the non-PIR imager and process the received image data to detect at least one object in the area of a defined type of object. The controller is also coupled to control operation of the light source based on, at least in part, detection of the ambient characteristic of the environment. Alternatively, one or more components of a system may be used to monitor traffic, with or without active illumination.Type: GrantFiled: March 2, 2012Date of Patent: November 15, 2016Assignee: EXPRESS IMAGING SYSTEMS, LLCInventors: William G.

Patent number: 9204523Abstract: Disclosed herein is a remotely adjustable lighting system. The lighting system includes a luminaire including one or more solid-state light systems and a non-line-of-sight wireless transceiver. The output intensity of the solid-state light systems is adjustable. The non-line-of-sight transceiver in the luminaire can receive one or more non-line-of-sight wireless signals transmitted by a transceiver in a general purpose handheld computing device. Instructions and data including configuration and output intensity adjustments may be communicated between the general purpose handheld computing device and the luminaire via one or more non-line-of-sight wireless signals.Type: GrantFiled: May 1, 2013Date of Patent: December 1, 2015Assignee: Express Imaging Systems, LLCInventors: William G.

Patent number: 8922124Abstract: Disclosed herein is a remotely adjustable lighting system with security features. The lighting system includes a lamp (e.g., luminaire) which carries solid-state light sources and a sensor. The solid-state light sources emit visible light at an adjustable output intensity. The sensor is responsive to line-of-sight wireless signals, and the lamp increases and decreases the output intensity of the light sources in response to output signals of the sensor. The lamp provides security features by selectively accepting and rejecting instructions carried by the line-of-sight wireless signals to vary the output intensity of the light sources.Type: GrantFiled: November 16, 2012Date of Patent: December 30, 2014Assignee: Express Imaging Systems, LLCInventors: William G.
