Patent number: 11578947Abstract: A sight magnifier assembly is configured to be releasably secured to a rail feature of a firearm to be used with a sight assembly to enhance a downrange image. The sight magnifier assembly includes a base configured to be releasably secured to the rail feature of the firearm and a housing rotatably coupled to the base. The housing is configured to support sight optics used to enhance or improve the downrange image. The assembly further includes a mechanism configured to enable the rotation the housing with respect to the base between a use position in which the sight optics is configured to be used with the sight assembly and a stored position in which the sight optics is moved so that the housing and the sight magnifier assembly is nearly completely obscured from the operator by the sight assembly as viewed along a longitudinal axis.Type: GrantFiled: April 27, 2021Date of Patent: February 14, 2023Assignee: RAYTHEON CANADA LTD. - ELCANInventor: John Maxwell Connolly

Patent number: 11320239Abstract: An optical system includes an aperture stop configured to direct light through the optical system, an inverting prism assembly configured to receive light from the aperture stop and direct light through the optical system, and a field stop configured to receive light from the inverting prism assembly and direct light through the optical system to an operator of the optical system. A point-of-impact is identified in object space and a point-of-aim is identified in afocal space of the optical system. The inverting prism assembly is configured to be pivoted about a center of the aperture stop to effect alignment of the point-of-impact and point-of-aim in the afocal space so that the point-of-aim is coincident with the optical axis.Type: GrantFiled: November 19, 2019Date of Patent: May 3, 2022Assignee: RAYTHEON CANADA LTD.—ELCANInventor: Gregory Mark Marshall

Patent number: 11294153Abstract: A system for delivering light from a light source to a digital micro-mirror device. The system includes one or more lens groups. At least one lens of the system is laterally displaced, so that its optical axis is not centered on the chief ray of the system.Type: GrantFiled: December 18, 2017Date of Patent: April 5, 2022Assignee: Raytheon Canada LTD.Inventor: Viktor Syvokin

Patent number: 11226173Abstract: An apparatus includes one or more light emitting diodes (LEDs) configured to be coupled to a power supply and to generate illumination, such as to generate a reticle in an optical scope. The apparatus also includes a first switch coupled in series with the one or more LEDs. The first switch is configured to selectively activate and deactivate the one or more LEDs based on whether the first switch is turned on or off. The apparatus further includes a low power detector configured to sense a low power condition of the power supply and to repeatedly turn the first switch on and off in response to the low power condition to cause the one or more LEDs to blink. The low power detector is configured to turn the first switch on and off at a given rate, and the given rate increases as the power supply is depleted.Type: GrantFiled: December 5, 2019Date of Patent: January 18, 2022Assignee: Raytheon Canada Ltd.Inventors: Kevin B. Wagner, Ryan W. Nobes

Patent number: 10921162Abstract: An apparatus for rotary encoding includes a knob configured to be rotated. The apparatus also includes multiple switches each configured to selectively form or not form a connection based on a current rotational position of the knob. The apparatus further includes a controller configured to generate or use a digital value associated with the current rotational position of the knob. The digital value is defined by which switches have or have not formed connections. Locations where the switches form the connections are selected such that the digital values uniquely identify different rotational positions of the knob and are non-sequential as the knob is rotated.Type: GrantFiled: January 24, 2020Date of Patent: February 16, 2021Assignee: Raytheon Canada Ltd.Inventors: Ryan W. Nobes, Kevin B. Wagner

Patent number: 10090640Abstract: A pulse-width modulation (PWM) light source drive for driving a light source is provided that includes a microcontroller, a modulation element, a voltage regulator, and a light detector. The microcontroller is configured to generate a PWM signal and an inverse PWM signal. The modulation element is configured to generate a drive signal based on the PWM signal. The light source is configured to be driven by the drive signal. The voltage regulator is configured to generate an output drive voltage for the light source. The light detector is configured to detect light energy emitted by the light source, to generate an optical power feedback signal based on the detected light energy, and to provide the optical power feedback signal to the voltage regulator during a laser-on driving interval. The microcontroller is configured to provide the inverse PWM signal to the voltage regulator during a laser-off driving interval.Type: GrantFiled: April 6, 2017Date of Patent: October 2, 2018Assignee: Raytheon Canada Ltd.Inventors: Kevin B. Wagner, Ryan Nobes
