Patent number: 11923799Abstract: An apparatus for regulating a slew time of an output voltage of a motor driver system includes a gate current control circuit which has a first input coupled to receive a target slew time and a second input coupled to receive a slew time. The gate current control circuit provides an incremented gate current if the slew time is greater than the target slew time and provides a decremented gate current if the slew time is less than the target slew time. The apparatus includes a gate driver which has a first input coupled to receive a PWM signal and a second input coupled to receive the gate current. The gate driver provides a gate drive signal.Type: GrantFiled: August 9, 2021Date of Patent: March 5, 2024Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Ashish Ojha, Krishnamurthy Shankar, Siddhartha Gopal Krishna, Priyank Anand, Ganapathi Hegde

Patent number: 11606632Abstract: This document describes textile assemblies for speakers, including textile assemblies with inlaid tensioning yarns, and associated apparatuses and methods. The textile assembly includes a textile body (106) with inlaid tensioning yarns (302, 304). The textile assembly (102) may be a fully-fashioned textile swatch. The tensioning yarns are inlaid at intervals in the textile body but can slide within or be pulled through the textile body. Further, the tensioning yarns have ends (306, 308, 402, 404) that are accessible near the edges of the textile body for various reasons. First, pulling on them while the textile assembly is on an acoustic device (104) tensions the tensioning yarns such that they limit movement of the textile assembly and break up vibration modes. Second, their ends can be tied directly to, formed into loops to hook over, or wound around, features (208) on the acoustic device to removably secure the textile assembly to the acoustic device.Type: GrantFiled: March 15, 2021Date of Patent: March 14, 2023Assignee: Google LLCInventors: Laura Charlotte Shumaker, Siddhartha Hegde, Anuja Bagul, Darren Torrie, Myrrhia R.

Patent number: 10590600Abstract: An item such as a fabric-based item may have a layer of fabric with openings that are illuminated by a light source. The openings may form symbols or other shapes and may serve as labels for keyboard keys or other components. The fabric may be formed from transparent strands of material that are coated with opaque material or may be formed from opaque strands of material in which openings are formed by laser drilling. The openings may be covered with a transparent coating layer such as a translucent polymer coating. Translucent material on the fabric may be patterned to form parts of the labels or other shapes created by the illuminated openings.Type: GrantFiled: January 17, 2017Date of Patent: March 17, 2020Assignee: Apple Inc.Inventors: Paul Xiaopeng Wang, Christopher T.

Patent number: 10566151Abstract: An item such as a fabric-based item may have one or more input devices. The input devices may have terminals that are electrically coupled to control circuitry. The control circuitry may make resistance measurements, capacitance measurements, and other measurements on the input devices to determine whether the input devices have been pressed by a user's finger or have otherwise received input. The input devices may be used to form an array of switches for a keyboard, may form buttons on an electronic device housing or case, may be part of an item of clothing, or may be incorporated into other items such as fabric-based items. The input devices may have collapsible fabric structures such as collapsible fabric domes. The terminals of the input devices may be formed from conductive strands of material in the fabric domes or may be supported by other structures that buckle under applied pressure.Type: GrantFiled: January 26, 2017Date of Patent: February 18, 2020Assignee: Apple Inc.Inventors: Paul Xiaopeng Wang, Siddhartha Hegde, Daniel D.

Patent number: 10427374Abstract: Electronic equipment may include seamless spacer fabric. Seamless spacer fabric may be used as a protective case or cosmetic cover for an electronic device such as a speaker. A seamless spacer fabric may include a seamless fabric outer layer, a spacer fabric inner layer, and an adhesive layer that bonds the seamless outer layer to the spacer fabric inner layer. The spacer fabric layer may have a seam region where one portion of the spacer fabric layer is joined with another portion of the fabric layer. The seamless fabric outer layer may cover the seam region to hide it from view. One or more additional seam hiding layers or strips may be formed on opposing sides of the spacer fabric layer to cover the seam. The seamless spacer fabric may have an array of openings that extends uniformly around the perimeter of the seamless spacer fabric.Type: GrantFiled: March 13, 2018Date of Patent: October 1, 2019Assignee: Apple Inc.Inventors: Yohji Hamada, Siddhartha Hegde, Zebinah P.

Patent number: 10377000Abstract: An accessory device suitable for use with an electronic device is disclosed and may be designed to provide a protective cover and dissipate heat from the device. Regarding the latter, the accessory device may include a thermally conductive layer disposed in the accessory device. The thermally conductive layer may extend from a first end of the accessory device proximate to a heat-generating component in the electronic device, to a second end away from the heat-generating component. The thermally conductive layer is designed to navigate heat away from the heat-generating component to the second end where the heat escapes the accessory device. The second end may include one or more openings to facilitate heat transfer from the accessory device. In other embodiments, the accessory device includes a phase change material that absorbs heat and changes to a liquid, then passes the heat to another location in the accessory device.Type: GrantFiled: August 26, 2015Date of Patent: August 13, 2019Assignee: Apple Inc.Inventors: Edward L. Siahaan, Siddhartha Hegde, Dhaval N. Shah
