Patent number: 11906745Abstract: Display backing components for head-mounted devices (HMDs) are described that reduce eddy currents in magnetic fields generated by a coil. A HMD may include a coil that is used to generate a magnetic field that may be used to track position of other devices with respect to the HMD. Display backing components, used to provide rigidity, are modified with holes or other gaps to interrupt the path of the eddy currents and reduce the interference with the magnetic field, thus improving the power efficiency of the coil and of the HMD. These modifications may be formed by casting, drilling, cutting or otherwise perforating the display backing during manufacture.Type: GrantFiled: April 14, 2022Date of Patent: February 20, 2024Assignee: Apple Inc.Inventors: Qianyi Zhao, Runren Zhang, Zhenggang Cheng, Jeffrey A Griffis, Stephen E Dey

Publication number: 20230333394Abstract: A head-mounted device or other electronic device may emit an alternating-current magnetic field. A wireless controller may have alternating-current magnetometers for monitoring the alternating-current field. The wireless controller may also have an accelerometer for measuring the orientation of the controller relative to the Earth's gravity and a direct-current magnetometer for measuring the orientation of the controller relative to the Earth's magnetic field. The alternating-current magnetometers may be three-coil magnetometers located at different locations in a controller housing. Using data from the alternating-current magnetometers, the direct-current magnetometer, the accelerometer, and/or other sensors, the wireless controller can determine the position and orientation of the wireless controller. This information can be wirelessly transmitted to the head-mounted device to control the head-mounted device.Type: ApplicationFiled: March 8, 2023Publication date: October 19, 2023Inventors: Yuhao Pan, Guangwu Duan, Jeffrey A. Griffis, John G. Elias, Krishna Prasad Vummidi Murali, Michael A. Lehr, Savas Gider, Stephen E. Dey

Patent number: 7658625Abstract: An external AC power adapter is provided in a compact form factor that utilizes an AC plug that swivels about the body of the adapter and that includes prongs (i.e., electrical contacts or terminals) which can fold into the body for transport or storage. The swiveling AC plug enables the body of the AC power adapter to be rotatably oriented in a user-selectable manner in order to fit in tight spaces when plugged in to maximize the utilization of available outlets. The foldable prongs help to minimize the overall size of the AC power adapter for easy portability and storage. When folded, the prongs are protected against damage and are prevented from damaging or scratching other articles when the AC power adapter is packed in a bag or suitcase during travel.Type: GrantFiled: March 7, 2008Date of Patent: February 9, 2010Assignee: Microsoft CorporationInventors: Matthew Jubelirer, Gary Rensberger, Jeffrey A.

Patent number: 6558046Abstract: An optical wavelength multiplexer and/or demultiplexer is provided having mechanical strain relief. The mechanical strain relief is provided by mounting ears carried by a molded coupling module supporting the fiber optic cable receptacle. The mounting ears are engaged by a pair of mounting plates carried by a housing for the device. Loads applied to the fiber optic cable receptacle are transferred to the housing frame and do not adversely affect the optical pathway of the assembled device.Type: GrantFiled: March 12, 2001Date of Patent: May 6, 2003Assignee: Blaze Network Products, Inc.Inventors: Jeffrey A.

Publication number: 20020131259Abstract: A method of EMI shielding the seam(s) of a multiple-part enclosure is provided herein. The enclosure can be produced and assembled quickly and inexpensively. An embodiment of the invention is formed of two conductive sheet metal parts that make up the outer enclosure of an optoelectronic transceiver. The parts come together in a way that allows for an interference fit, and requires a press fit operation for complete engagement. A series of recesses along the edge of one part and a series of oversized (in relation to the recesses) teeth in the other part provide the interference fit. The oversized teeth are pressed into the recesses, providing metal-to-metal contact at regular intervals along the interface. Contact at regular intervals provides a robust EMI shield against electromagnetic waves incident to the enclosure's interior or exterior.Type: ApplicationFiled: March 15, 2001Publication date: September 19, 2002Inventors: Yoram Rozy, Jeffrey A. Griffis, Hong Li

Publication number: 20020129954Abstract: A method and apparatus are provided for mounting a printed circuit board (PCB) in an optoelectronic transceiver housing. The mounting technique is quick, easy and requires no secondary adhesive or hardware. The PCB is mounted into an injection molded plastic housing that is plated with a conductive material. In its mounted state, the PCB deflects a spring feature of the housing such that the PCB is located securely therein. The PCB is preloaded against the plated plastic in order to electrically connect the PCB ground to the chassis ground.Type: ApplicationFiled: March 15, 2001Publication date: September 19, 2002Inventor: Jeffrey A.

Publication number: 20020126951Abstract: Optical to electrical and electrical to optical conversion assemblies provide precise and stable alignment, low loss, unperturbed electrical transmission and high thermal conductivity. Mechanically isolating the ceramic substrate of the conversion assembly relative to the surrounding structures enables good long-term optical alignment. Electrical transmission line connections to and from the optical conversion circuits on the ceramic substrates are made via flexible circuit board designs. The alignment of the components on the substrate relative to the plastic optics is thus preserved. The flexible circuit board includes a cross hatched ground layer, which relieves portions of the metallization below the signal layer and yet is able to maintain the desired transmission line properties. Electrical to optical conversion circuits are provided where the transmission of the electrical signals to the converter circuits is accomplished with minimal loss and with good signal integrity.Type: ApplicationFiled: March 14, 2001Publication date: September 12, 2002Inventors: Robert A. Sutherland, James S. Sacks, Eric B. Grann, Kenneth R. Herrity, Jeffrey A. Griffis, Frank W. Jacobson
