Patent number: 11949281Abstract: Systems and methods described herein provide examples of an electrical panel (e.g., a modular electrical panel) that is configured to control a plurality of electrical loads. The electrical panel may include a control circuit, memory, a communication circuit, and an alternating current (AC) line feed and/or a direct current (DC) line feed. The electrical panel may also include a plurality of power supplies and a plurality of control modules, where more than one control module is associated with each of the plurality of power supplies. Each control module may configured to receive DC power from the associated power supply and provide an output voltage to at least one electrical load. The electrical panel provides flexibility as to whether each stage of conversion, regulation, and/or control is performed at a control module located within the electrical panel or performed at an accessory module located at an electrical load.Type: GrantFiled: April 27, 2023Date of Patent: April 2, 2024Assignee: Lutron Technology Company LLCInventors: Stuart W. DeJonge, Robert C. Newman, Jr., Matthew W. Nuhfer, Michael W. Pessina, Thomas M. Shearer

Patent number: 11930574Abstract: A controllable lighting device may utilize a controllable impedance circuit to conduct a load current through an LED light source. The controllable impedance circuit may be coupled in series with a first switching device, which may be rendered conductive and non-conductive via a pulse-width modulated signal to adjust an average magnitude of the load current. The controllable lighting device may further comprise a control loop circuit that includes a second switching device. The second switching device may be rendered conductive and non-conductive in coordination with the first switching device to control when a feedback signal is provided to the control loop circuit and used to control the LED light source. The control loop circuit may be characterized by a time constant that is significantly greater than an operating period of the load current.Type: GrantFiled: May 23, 2022Date of Patent: March 12, 2024Assignee: Lutron Technology Company LLCInventors: Stuart W. DeJonge, Robert C. Newman, Jr.

Patent number: 8887370Abstract: In certain embodiments, a fence system includes a rail having a first surface having one or more apertures. The rail also includes second and third surfaces opposing one another, the first, second, and third surfaces of the rail forming a channel. The second surface and the third surface of the rail have first and second lips, respectively, the first and second lips extending into the channel. The fence system section also includes one or more pickets inserted through corresponding apertures of the first surface of the rail. Each picket has a first connection region located substantially in the channel formed by the first, second, and third surfaces of the rail such that the first connection region is substantially prevented from passing through the corresponding aperture in the first surface of the rail or between the opening defined by the first and second lips of the rail.Type: GrantFiled: March 25, 2013Date of Patent: November 18, 2014Assignee: Betafence USA LLCInventors: John F. Payne, Robert W. Newman, Donald G. Keilers

Patent number: 4719406Abstract: There is provided a phantom for measuring a performance parameter of a nuclear magnetic resonance scanner capable of acquiring NMR data from a study object. The phantom is made up of a housing composed of a substantially non-NMR-active material, and positionable in use within a radio-frequency coil forming part of an NMR scanner. The phantom further includes a first medium disposed within the housing to load the radio frequency coil in a manner similar to that of a patient. The NMR properties of the medium are further selected such that an NMR signal, if any, produced by the medium occurs at a time other than when a performance parameter of said NMR scanner is measured. In the preferred embodiment, the phantom comprises two concentrically disposed cylinders of different diameters and a pair of end plates fastened to opposite ends of the cylinders. The first medium is disposed within the volume defined between the side walls of the cylinders and the end plates.Type: GrantFiled: February 7, 1986Date of Patent: January 12, 1988Assignee: General Electric CompanyInventors: Daniel J. Schaefer, Robert W. Newman

Patent number: 4644276Abstract: Three-dimensional NMR phantom includes in the preferred embodiment a set of three mutually orthogonal test plates each configured to enable testing NMR scanner performance in each of the planes containing the plates. The plates are further arranged so as to be simultaneously positionable, in use, at the isocenter of the NMR scanner to permit testing NMR scanner performance in each plane without repositioning the phantom.Type: GrantFiled: September 17, 1984Date of Patent: February 17, 1987Assignee: General Electric CompanyInventors: Thomas J. Sierocuk, Robert W. Newman
