  • Publication number: 20170223637
    Abstract: A wireless charging system has a transmitter and a receiver. The transmitter has (i) a TX coil that wirelessly transfers power to the receiver and (ii) TX circuitry that powers the TX coil and detects receiver removal by comparing TX input power and TX power loss. The TX circuitry can determine (1) TX input power as the product of sampled TX input current and voltage and (2) TX power loss using a mapping based on sampled TX coil current. When the receiver is present, the difference between TX input power and TX power loss has a first value and when the receiver is removed, the difference has a second, lesser value. The transmitter detects removal of the receiver by determining when the difference decreases below a specified threshold level. By frequently generating and analyzing the difference, the transmitter can quickly detect receiver removal and safely power down the TX coil.

  • Patent number: 9613874
    Abstract: Methods for evaluating semiconductor device structures are provided. In one example, a method includes forming a support layer on a first side of a lamellar sample portion of the semiconductor device structure. The lamellar sample portion has a second side opposite the first side, a target analysis area on or proximate the first side, and a first thickness defined from the first side to the second side. The second side is milled to form a reduced thickness lamellar-supported sample portion that has a milled second side opposite the first side. The support layer is removed from the reduced thickness lamellar-supported sample portion to form a reduced thickness lamellar sample portion having a second thickness that is defined from the first side to the milled second side and that is less than the first thickness. The target analysis area of the reduced thickness lamellar sample portion is evaluated.

  • Patent number: 9581506
    Abstract: Methods for evaluating strain of crystalline structure are provided herein. In accordance with an exemplary embodiment, a method for evaluating strain of a crystalline structure includes directing an electron beam at the crystalline structure to produce an electron diffraction pattern including a reflection point area. The electron diffraction pattern is detected with a detector that includes a plurality of pixels to produce a raw data set. The raw data set is filtered by applying a mathematical median filter to produce a filtered data set, and a contrast of the filtered data set is enhanced to produce an enhanced data set. A center point of the reflection point area is determined with the enhanced data set, and the strain of the crystalline structure is determined based on analysis of the center point.

  • Patent number: 9307308
    Abstract: This application relates to methods and apparatus for waterproofing an electronic device having an audio output. More particularly a method for dynamically forming an acoustic volume of air for a speaker component is disclosed. The dynamically formed acoustic volume creates a sealed volume of air that prevents moisture from entering a portion of the device that includes moisture sensitive components. By dynamically forming the acoustic volume during a blow forming operation, the acoustic volume can utilize unused space within the electronic device in a highly efficient manner by occupying small areas of unused space that would otherwise go unused.

  • Patent number: 9206339
    Abstract: A method of preparing a polyester/polyolefin hot-melt adhesive for use in a solar cell bus bar is disclosed, in which 2,6-naphthalenedicarboxylic acid and ethylene glycol are first sequentially subjected in a predetermined ratio to esterification and polycondensation in the presence of a certain amount of a titanium-based catalyst to result in a polyethylene naphthalate (PNT) with a weight-average molecular weight of 16,000˜20,000. The PNT is then melt-blended with a low-density polyethylene (LDPE) in the presence of a compatibilizer to produce the hot-melt adhesive that can be shaped into films having a high light transmittance, good mechanical properties, high heat and yellowing resistance and thus particularly suitable for use in solar cell bus bars.
