Patent number: 10185397Abstract: An electromagnetic actuator provides haptic feedback in a computing device. The electromagnetic actuator includes an actuator gap between the moveable actuator plate and the actuator. A gap sensor measures the actuation gap between the force plate and the actuator. The gap distance between the moveable actuator plate and the actuator may vary due to various environmental or user factors. The amount of haptic feedback provided to a user may be made consistent by adjusting the force exerted by the actuator on the actuator plate in response to measured variations in the gap distance.Type: GrantFiled: September 8, 2015Date of Patent: January 22, 2019Assignee: Apple Inc.Inventors: Shingo Yoneoka, Chun Chit Lam, Scott J. McEuen, Peteris J. Augenbergs

Patent number: 9599772Abstract: Embodiments include a high bandwidth optical connection system suitable for interconnecting servers, for example within a rack of a datacenter. An edge mount optical connector assembly includes an edge-mount housing providing topside socket contacts proximate to a first end of the housing and a port at a second end to receive an optical plug connector. A socket latch cantilevered from an anchor point on the housing includes a latching face to contact a keeper face disposed on the housing and a spring load application surface between the anchor point and the latching face to apply a spring force against the electrical contacts for retention of a removable optical transceiver module. An optical plug connector includes a front housing joined to a rear housing with a plug lens spring loaded within the housing and with alignment features comprising two flat alignment surfaces orthogonally oriented relative to each other.Type: GrantFiled: May 18, 2016Date of Patent: March 21, 2017Assignee: Intel CorporationInventors: Qi Qi, Jamyuen Ko, Chun Chit Lam

Patent number: 9575269Abstract: Described are embodiments of apparatuses and systems of an active optical cable assembly including a connector plug configured to resist stress to optical fibers of the cable assembly. The connector plug may include a light engine mounted on a substrate, a jumper mounted on the substrate and configured to convey optical signals between an optical fiber and the light engine, and a fiber holder assembly configured to constrain motion of the optical fiber, the fiber holder assembly including a fiber holder on a first side of the substrate and a fiber holder cover on a second side of the substrate such that the optical fiber is fixedly held between the fiber holder and the fiber holder cover. Other embodiments may be described and/or claimed.Type: GrantFiled: March 18, 2013Date of Patent: February 21, 2017Assignee: Intel CorporationInventors: Chun Chit Lam, Jamyuen Ko

Patent number: 9128248Abstract: An optical lens connector includes alignment features for passive connection alignment. The alignment features are C-shaped and have generally planar surfaces to interface with a mating connector. The alignment features passively align an optical fiber with an optical lens in the optical lens connector, by fitting adjacent to planar surfaces of the mating connector. When interfaced together, the alignment features restrict lateral and vertical motion of the connectors with respect to each other, which helps keep the optical lens aligned with the optical fiber.Type: GrantFiled: November 23, 2011Date of Patent: September 8, 2015Assignee: Intel CorporationInventors: Chun Chit Lam, Jamyuen Ko
