Abstract:
The invention relates to a liquid-crystalline medium containing one or more compounds of the formula I and one or more compounds selected from the group of the compounds of the formula IA to IE in which R0, R1, R2, X0, X1, X2, A1, Z1, m, p, q, v have the meanings indicated in Claim 1, and to the use thereof in electro-optical liquid-crystal displays.
Abstract:
A juice extractor is adapted to squeeze juice from oranges and similar kinds of fruits. The juice extractor includes a juice extractor base and a juice squeezing wheel rotatably disposed on the juice extractor base. An arcuate concave surface is formed on an upper portion of the juice extractor base. The juice squeezing wheel has an involute outer surface. A crushing space is defined between the juice squeezing wheel and the concave surface of the juice extractor base for receiving a half-cut fruit. When the juice squeezing wheel rotates, the half-cut fruit in the crushing space is crushed to produce fruit juice. The juice extractor can squeeze juice electrically, is structurally simple and is convenient to be washed.
Abstract:
Auto focus methods for electronic cameras are disclosed. The method of the present invention obtains and compares evaluation values (high frequency component (HFC)) corresponding to desired image signals from left or right locations relative to a center of a zoom lens of an electronic camera, thereby locating the maximal evaluation value. The location corresponding to the located maximal evaluation value is an optimum focus location.
Abstract:
A sterilization apparatus for a portable electronic device including a cabinet and a carrier is provided. The carrier includes a base slidably disposed on the cabinet, multiple first positioning elements and multiple second positioning elements disposed in parallel on the base, multiple sterilization light sources corresponding to the second positioning elements and multiple pressure sensors disposed in parallel in the base. The base is configured to carry at least one portable electronic device. One second positioning element is disposed between any two adjacent first positioning elements, and any first positioning element and any second positioning element adjacent to each other are separated by a positioning space. The pressure sensors are respectively located in the positioning spaces. One sterilization light source is disposed between any two adjacent pressure sensors, and the pressure sensors are configured to sense a pressure from the portable electronic device.

Abstract:
The instant invention relates to dielectrically positive nematic media comprising one, two or more compounds of formula I one or more compounds selected from the group of formulae II and III and one or more compounds selected from the group of formulae IV and V wherein the parameters are as defined in claim 1 with the proviso that the media comprise one or more compounds of formula III, wherein n and o both are 1 and all rings are 1,4-phenylene, which independently of each other optionally are fluorinated once or twice, and/or one or more compounds of formula V, wherein q is 2, as well as to liquid crystal displays comprising these media, especially to TN-displays and in particular to active matrix displays.
Abstract:
A device is presented for computing an optical center of a sensor array relative to a lens. The sensor array includes a plurality of sensor units, and each sensor unit has a position on the sensor array. The lens defines an optical axis. The device includes a configuration module and a processing circuit. The configuration module is provided for positioning the lens and the sensor array thereon. When test light is parallel to the optical axis and is incident to the lens, the sensor array receives the test light transmitted by the lens so that each sensor unit outputs a value. The processing circuit is linked to the sensor array for receiving values outputted from the sensor units and selecting positions of sensor units outputting a specific value among the values, for computing the optical center of the sensor array.
