  • Publication number: 20180372939
    Abstract: Electrical equipment such as a tablet computer cover, a laptop computer, or other equipment may include keys. Each key may have a key member. Coatings such as opaque coating layers may be formed on the key members. Opaque coating layers may be patterned to form symbol-shaped openings associated with key labels. Opaque coating layers may also have recessed peripheral portions and other features to enhance the appearance of the keys. Metal coating layers such as physical vapor deposition metal layers may be incorporated into the keys. Key members may have outer surfaces and opposing inner surface on which patterned coating layers may be formed. Peripheral edge portions of the key members may extend between the outer and inner surfaces and may be coated with metal coating layers to form reflective metal trim structures. Backlight illumination for the keys may be formed form light sources such as light-emitting diodes.

  • Patent number: 10151600
    Abstract: As part of a technique for positioning viewports over interactive digital maps, a digital map of a geographic area is provided via a user interface of a computing device. The currently visible portion of the digital map is displayed in a viewport. A user gesture is detected, where the user gesture communicates a particular acceleration to the viewport, along a particular direction, to move the viewport from its current position to a target position over the digital map. A current user context for the digital map is determined. A new position of the viewport over the digital map is determined in accordance with (i) the user gesture and (ii) the current user context, such that the new position is different from the target position, and the viewport is moved from its current position to the new position.

  • Publication number: 20180339066
    Abstract: The present invention provides methods for enhancing transduction efficiency of a viral vector into a host cell such as a stem cell. The methods involve transducing the host cell with the vector in the presence of an inhibitor of mTOR complexes (e.g., rapamycin or analog compound thereof). Also provided in the invention are kits or pharmaceutical combinations for delivering a therapeutic agent into a target cell with enhanced targeting frequency and payload delivery. The kits or pharmaceutical combinations typically contain a viral vector encoding the therapeutic agent, and an inhibitor of mTOR complexes.

  • Patent number: 10139455
    Abstract: Correlated double sampling (CDS) for magnetoresistive (MR) sensors is provided. Here the MR sensor output is sampled at two closely spaced times. The first sample is MR signal+baseline+noise and is sampled when the modulated magnetic field is non-zero. The second sample is baseline+noise only because it is sampled when the modulated magnetic field is zero. The difference between the first and second samples will have significantly reduced low frequency noise and baseline cancellation. Modulation of the electrical bias provided to the MR sensor can be used to provide a baseline signal for temperature compensation. In a second aspect, we provide MR sensor arrays having input and output multiplexing and demultiplexing for row and column line selection, in combination with a per-sensor switch to prevent noise accumulation and bandwidth reduction from idle MR sensors.

  • Patent number: 10141626
    Abstract: An electronic device may be provided with wireless circuitry that includes a radio-frequency transceiver circuit and an antenna. The antenna may be a patch antenna formed from a patch antenna resonating element and an antenna ground. The patch antenna resonating element may be formed from a metal patch on a printed circuit board. The antenna ground may be formed from a metal housing having a planar rear wall that lies in a plane parallel to the metal patch. The radio-frequency transceiver circuit may be coupled to the metal patch through traces on the printed circuit and may be coupled to rear wall of the housing through a screw and a screw boss in the housing. Buttons and other electrical components may be mounted on the printed circuit board and may be coupled to control circuitry on the printed circuit board through the metal patch.

  • Publication number: 20180337010
    Abstract: An electronic device such as a cover for a portable device or other electronic equipment may have circuitry mounted in a housing. The housing may be formed from layers of material such as fabric and polymer layers. The circuitry of the electronic device may include components mounted on a printed circuit. The components may include movable components such as keys in a keyboard. A fabric layer may overlap the keys. Border regions of the fabric layer that surround each key may be characterized by a stiffness. To ensure that the keys or other movable components in the device exhibit satisfactory stiffness levels, the keys can be tested and selected border regions or other fabric layer portions may be laser ablated or otherwise processed to locally reduce fabric layer stiffness.

  • Publication number: 20180312911
    Abstract: A method of methylation detection provides a quantitative description of the methylation density in DNA strands. Bisulphite conversion [100] of the DNA strands containing methylated and unmethylated sites creates converted DNA strands with mismatch base pairs. The converted DNA strands are PCR amplified [102], and single strand target DNA strands are magnetically labeled [104] and hybridized [106] with complementary DNA strands immobilized onto a magnetoresistive (MR) sensor array. During hybridization, a binding signal may be recorded. A stringency condition such as temperature or salt concentration is increased [108] to cause the magnetically labeled single strand target DNA strands to be denatured from the complementary DNA strands immobilized onto a magnetoresistive (MR) sensor array.

  • Publication number: 20180313789
    Abstract: Improved temperature measurement and correction is provided for magnetoresistive sensor arrays. A linear coefficient of resistance vs. temperature is determined from one or more reference sensors in the array by measuring resistance of the reference sensors at known temperatures, which enables resistance measurements to be used to determine unknown temperatures in all sensors of the array. Double modulation leads to MR sensor outputs having center tones which can be used to correct temperature dependence in side tone MR signals. This correction can be according to a linear fit or a polynomial fit. Applications include biological assays requiring accurate temperature data, such as accurate determination of DNA melting curves.
