  • Patent number: 11201387
    Abstract: Mobile computing devices often incorporate a window along a discrete portion of a perimeter of a metallic device case adjacent the antennae and a plastic cover that covers the window and seals antennae within the mobile computing device. As mobile computing devices shrink in physical size and weight and become more portable, available space within the mobile computing devices for the antennae shrinks. Merely increasing the size of the connectivity window to occupy up to a full width or length of the perimeter of the metallic device case may negatively impact overall device stiffness requirements. The electrically isolated corner stiffeners described herein may permit larger antennae windows for wireless connectivity, while meeting applicable stiffness requirements for an associated mobile computing device.

  • Patent number: 10698267
    Abstract: A device is disclosed, which may include a color-filter layer and a thin-film transistor (TFT) layer. The TFT layer may have an alignment layer. The device may have spacers, between the color-filter layer and the TFT layer, that form space between the color-filter layer and the TFT layer for liquid crystals. The device may include a scratch-resistant coating on the alignment layer of the TFT layer.

  • Patent number: 10352789
    Abstract: A display includes a thin-film transistor (TFT) glass layer having a top surface and a bottom surface and a color-filter glass layer having a top and a bottom surface. The TFT glass layer extends beyond the color-filter glass layer to form an overhanging portion of the TFT glass layer. The overhanging portion is flexible, and a flexible printed circuit (FPC) is affixed to the overhanging portion. The FPC includes an integrated strain gauge for measuring strain at a plurality of locations on the overhanging portion of the TFT glass layer. The display device may be incorporated into a chassis to secure the display in the device. A processor, within the housing, may instruct the strain gauge to measure the strain.

  • Patent number: 10247970
    Abstract: A display includes an integrated strain-gauge layer in or on the display for measuring the strain at a plurality of locations on the display. The display is deformable and secured to a display device by a first chassis. A method includes measuring, over a period of time, strain of the display of a first device at the plurality of locations and recording the strain measurements in a memory of the display device. Strain measurements associated with a failure of the display may be identified. The method may include simulating a dynamic system including a model of a second device. The model of the second device includes a model of a second chassis different than the first chassis and a model of the display associated with the failure. Simulating the dynamic system may include simulating deformation of the model of the display based on the identified strain measurements.

  • Publication number: 20180332150
    Abstract: To address the issue of securely joining thin sections of magnesium housing, a computing device with a housing, a metal strip, and a plastic interlock structure is provided. The housing may include adjacently arranged first and second metal sections separated by a void. The metal strip may have a hole with an undercut region formed therein, and it may be joined to a surface of one of the metal sections. The plastic interlock structure may be positioned at least partially in the void, and the metal strip may be embedded in the plastic interlock structure to strengthen the joint between the metal sections of the housing. The plastic interlock structure may physically and electrically isolate adjacent metal sections from one another to form an antenna that permits transmission of radio waves.

  • Patent number: 10129623
    Abstract: An electronic device in accordance with a particular embodiment of the present technology includes a rigid covering substrate, an acoustic port extending through the covering substrate, an acoustic transducer carried by the covering substrate, and another electronic component (e.g., a touch sensor or an antenna) also carried by the covering substrate. The electronic device can also include processing circuitry and an array of electrodes through which the acoustic transducer and the other electronic component are electrically connected to the processing circuitry. The array of electrodes can be part of a flexible circuit board extending between a contact region of the covering substrate and the processing circuitry. The transducer lead can extend between a region of the covering substrate including the acoustic port and the contact region.
