Publication number: 20240136866Abstract: A camera module includes a camera, a charging coil, and a magnetic assembly. The charging coil is located in a bottom portion of the camera module. The charging coil provides wireless charging of the camera. The magnetic assembly is located in a rear portion of the camera module. The magnetic polarities of the magnetic assembly produce a large magnetic flux outside the camera module and a low magnetic flux within the camera module.Type: ApplicationFiled: October 20, 2022Publication date: April 25, 2024Inventors: Brandon Brocklesby, Jason S.

Patent number: 11905742Abstract: An information handling system housing is secured against unauthorized access with a security device integrated in the housing that selectively enables and disables screw movement relative to threads disposed in the housing. For instance, a freewheeling nut in the housing interfaces with an actuator that selectively releases or holds the freewheeling nut relative to the housing. When released, a screw coupled to the freewheeling nut cannot rotate relative to the threads of the freewheeling nut so that the screw maintains the housing secured until the freewheeling nut is held in position to allow removal of the screw.Type: GrantFiled: April 24, 2020Date of Patent: February 20, 2024Assignee: Dell Products L.P.Inventors: Jason S. Morrison, Nicholas D. Grobelny

Patent number: 11822394Abstract: A portable information handling system keyboard includes plural keys that each have a programmable variable-feel response to an end user experience with key interactions in real time. In one example embodiment, a magnetic-rheological fluid is disposed in a chamber of the key to pass through openings formed in a piston that moves downward with a keypress and upward in response to a biasing mechanism, such as a spring disposed in the chamber. Current applied to a coil around the chamber creates a magnetic field that varies the viscosity of the fluid so that key compression and range of motion associated with an input as well as key movement to a raised position are programmable to adjust based upon a sensed key position and movement.Type: GrantFiled: January 12, 2021Date of Patent: November 21, 2023Assignee: Dell Products L.P.Inventor: Jason S. Morrison

Patent number: 11662779Abstract: A portable information handling system rotationally couples housing portions with a variable torque hinge having a first axle that rotates with a first housing portion, a second axle that rotates with a second housing portion and a synchronizing gear assembly that translates rotation between the first and second axles. Variable torque is applied by selectively engaging and disengaging a coupler gear with the synchronizing gear assembly to apply and remove an increased torque that resists housing rotation. In one embodiment, the coupler gear is an idler gear of the synchronizing gear mechanism that selectively applies and removes an increase torque of the second axle to the first axle. The coupler gear slides in response to an actuator, such as an electro-permanent magnet acting on a ferromagnetic material with high and low magnetic attraction states.Type: GrantFiled: June 30, 2020Date of Patent: May 30, 2023Assignee: Dell Products L.P.Inventors: Jason S.

Patent number: 11348746Abstract: An electro-permanent magnet key assembly may comprise an electro-permanent magnet generating a magnetic field when a direction of current applied to an electrically conductive wire coiled around a low-coercivity magnet, and a pair of scissor plates operably connected to the electropermanent magnet, such that the scissor plates rotate away from one another in the presence of downward force on a key cap situated atop the scissor plates. The top surface of the key cap may lie flush with adjacent keys of a keyboard when the key cap is in a neutral position. The electro-permanent magnet key assembly may further comprise a ferromagnetic flange operably connected to one of the scissor plates having angled overlap protrusions situated adjacent to the electropermanent magnet when the key cap is not in the neutral position, such that the angled overlap protrusions are attracted toward the magnetic field to return the key cap to the neutral position.Type: GrantFiled: May 7, 2019Date of Patent: May 31, 2022Assignee: Dell Products, LPInventors: Jason S.

Patent number: 11342103Abstract: De-magnetization protection is provided for electro-permanent magnets during information handling system manufacture and use by monitoring thermal conditions at the information handling systems to detect a thermal state associated with de-magnetization and commanding the electro-permanent magnets to an off state so that both magnets in the electro-permanent magnet have opposing polarities. The opposing polarities tend to stabilize magnet polarity to prevent de-magnetization during increased temperatures. Normal operations are then re-enabled once temperatures decrease.Type: GrantFiled: June 30, 2020Date of Patent: May 24, 2022Assignee: Dell Products L.P.Inventors: Jason S. Morrison, Mark A. Casparian

Publication number: 20220037101Abstract: Information handling system keyboard illumination is provided with micro LEDs disposed below keyboard keys to direct illumination at each key individually. The micro LEDs may be integrated at a bottom surface of a support plate below a keyboard membrane, on top of the support plate within an opening of the membrane or in a spacer layer of the membrane between circuit layers. A diffuser disposed between the micro LED helps to diffuse illumination directed at the key for a more even icon illumination. The diffuser may be integrated with the membrane at an upper circuit layer or over a structure disposed over the micro LED.Type: ApplicationFiled: July 28, 2020Publication date: February 3, 2022Applicant: Dell Products L.P.Inventors: Brandon J.

Patent number: 11230860Abstract: A dual-contact electro-permanent magnet (EPM) assembly of an information handling system may comprise a plurality of high-coercivity magnets situated on opposite ends of a low-coercivity magnet, a first EPM magnetic contact disposed between a first of the plurality of high-coercivity magnets and the low-coercivity magnet, and a second EPM magnetic contact disposed between a second of the plurality of high-coercivity magnets and the low-coercivity magnet. The low-coercivity magnet polarity may correlate to a direction of current pulse applied to an electrically conductive wire coiled around the low-coercivity magnet, and dependent upon the low-coercivity magnet polarity, the first EPM magnetic contact is capable of operating in an attractive magnetic state to attract a ferromagnetic contact of a peripheral device while the second EPM magnetic contact is magnetically neutral with respect to the ferromagnetic contact.Type: GrantFiled: June 13, 2019Date of Patent: January 25, 2022Assignee: Dell Products, LPInventors: Jason S.
