    摘要： An electrical connector includes an insulating housing having a mating cavity and at least a contact retained in the housing. The contact defines a retaining portion, a resilient arm extending forwards from a front edge of the retaining portion and a soldering portion extending out of the housing. The resilient arm defines a contacting portion projecting into the mating cavity at a front end thereof and a skirt bending from a side edge of the resilient arm and angled with the resilient arm. The skirt provided in the resilient arm can enhance the rigidity of the contact.

    摘要： In a control circuit for a light-emitting device, a reference voltage generation circuit detects a full-wave rectified voltage and generates a first voltage as well as generating a second voltage by converting the rectified voltage into a DC voltage. A voltage corresponding to a difference between the first voltage and the second voltage or a voltage corresponding to a ratio of the first voltage to the second voltage is generated as a reference voltage by a subtraction circuit or by a division circuit, respectively. As a result, a change in amplitude of the reference voltage can be suppressed when amplitude of the rectified voltage is varied due to a variation in an AC input voltage supplied from an AC power supply.

    摘要： A method for processing an image divided into blocks of pixels is disclosed. The method comprises the steps of: detecting, for each block, a largest sub-block whose pixels have an equal luminance value; identifying, for each block, if the detected largest sub-block is or is not a natural texture; determining, for each block, a block blockiness level on the basis of the number of pixels within the detected largest sub-block and on the basis of the identification step; and processing the image on the basis of the block blockiness levels.
