Patent number: 11913634Abstract: Apparatus and methods for enhanced lighting. The apparatus may include a light-transmitting body. The apparatus may include a light projector. The projector may be configured to propagate into the light-transmitting body an incoming incoherent light. The projector may be configured to propagate into the light-transmitting body an incoming visible coherent light. Emerging coherent light within a visible wavelength rage attributable to the incoming visible coherent light may have a first intensity. The first intensity may be greater than a second intensity. The second intensity may be an intensity of any emerging coherent light that is within the wavelength range and is attributable to the incoming incoherent light. Emerging light may be light that emerges from the light-transmitting body.Type: GrantFiled: May 5, 2022Date of Patent: February 27, 2024Assignee: Wangs Alliance CorporationInventors: Shelley S.

Patent number: 11864287Abstract: Circuitry to control dimming of a load circuit may be connected between a 0-10 V dimmer that outputs a DC voltage control signal and the load circuit. The circuitry may include a microcontroller that may be programmed to generate a first pulse-width modulated (“PWM”) signal having a duty cycle based on the dimming level configured to be set on the dimmer. A voltage conversion circuit may supply the microcontroller with data relating to the set dimming level. The microcontroller may be programmed to synchronize the first PWM signal with the supplied AC power from the main circuit based on a second PWM signal from a voltage detection circuit, such as a zero crossing voltage detection circuit. The first PWM signal may be supplied from the microcontroller to an on/off switch to chop the AC power waveform at certain intervals and thereby dim the load.Type: GrantFiled: May 31, 2023Date of Patent: January 2, 2024Assignee: Wangs Allliance CorporationInventors: Wai Ho Choy, Yumeng Sha, Haisheng Zhou, Wei Gao

Patent number: 10300589Abstract: A fastening tool assembly has a magazine body in a sleeve to convey fasteners to a housing outlet. Pivoting a lever relative to the housing, translates a knife to a loaded position, thereby disengaging from the knife, permitting a spring to return the knife to an unloaded position to drive a fastener through the outlet. A handle is pivotally connected to the housing. A roller is directly connected to the lever and the handle for permitting translation of the lever relative to the handle as the lever and the handle are pivoted relative to the housing. A spring-loaded bracket is operably connected to the magazine body for translation and rotation relative to the body. A latch is mounted to the housing to engage the bracket and maintain the magazine body in a retracted position, and is movable to a disengaged position wherein the bracket extends from the magazine body.Type: GrantFiled: February 28, 2013Date of Patent: May 28, 2019Assignee: ARROW FASTENER COMPANY, LLCInventors: Jonathan Sokol, Stephen Craig Pennington, Wai Ho Choy, Michael Reedy

Patent number: 9586311Abstract: A fastening tool assembly is provided with a housing with a contact surface, a longitudinal magazine receptacle, and a fastener outlet provided through the contact surface. A magazine body is received within the magazine receptacle to translate to a retracted position whereby a proximal end is adjacent the fastener outlet to store fasteners within the receptacle and to convey the fasteners to the fastener outlet, and to translate to an extended position whereby the body extends at least partially out of the receptacle for receipt of fasteners to the receptacle. A blocker is mounted to a side of the magazine body spaced apart from the fastener intake side. The blocker has a transverse width greater than a width of the body for blocking intake of fasteners to a wrong side of the body. Instructional indicia are provided on the blocker to instruct a user regarding proper fastener installation.Type: GrantFiled: April 19, 2013Date of Patent: March 7, 2017Assignee: Arrow Fastener Co., LLCInventor: Wai Ho Choy
