Abstract: A golf putter assembly includes a putter including a head, a display unit disposed in the putter, and a detecting unit disposed in the putter and electrically coupled to the display unit. The detecting unit is operable to detect and record a stationary starting position of a golf ball. The detecting unit is further operable to detect, during a practice swing, an instantaneous speed of the head as the head moves past the starting position, and to calculate what would be an initial speed of the golf ball if the golf ball was actually hit by the head with reference to the instantaneous speed of the head detected thereby. The detecting unit further performs control such that the initial speed of the golf ball as calculated is displayed on the display unit.

Abstract: A light-shielding module including a bracket, a pendulous member, a shielding member, a first magnet, a second magnet and a first coil is provided. The pendulous member has a first end and a second end opposite to each other and is pivoted on the bracket. The first end extends along a direction from a pivoting place of the pendulous member to a top of the bracket. The shielding member is connected to the first end. The first magnet is disposed at the pendulous member and located between the pivoting place and the first end. The second magnet is disposed at the pendulous member and adjacent to the second end. A mass-of-center of the second magnet is located beside a center line passing a center-of-mass of the first magnet and the pivoting center. The first coil is disposed on one of the first side wall and the second side wall.

Abstract: An imaging displacement module including a frame, an optical element, a carrier, a connecting portion and at least a first actuator is provided. The frame has a first opening, and the optical element, the carrier, the connecting portion and the first actuator are all disposed in the first opening. The carrier is capable of carrying the optical element, and the connecting portion connects between the frame and the carrier and capable of generating an elastic torsion around an axis. The first actuator is disposed at a side of the carrier and capable of driving the carrier to vibrate periodically.

Abstract: An adapter card for receiving a mini MMC memory card to form a SD memory card is disclosed to include a housing formed of a top cover shell and a bottom cover shell, and a terminal holder set, which includes an electrically insulative holder block, and a plurality of terminals formed integral with a material bar and bonded with the material bar to the electrically insulative holder block by insert-molding and cut off from the material bar after insert-molding.

Abstract: A multilayer circuit board has a first insulating layer, a first grounding grid layer and a transmission layer. The first grounding grid layer is formed below the bottom surface of the first insulating layer and has multiple grids. The grids are arranged in an array pattern and are made of metal, and each grid has a centerline and a shape. Centerlines of adjacent grids are separated by a first distance. The transmission layer is formed on the top surface of the first insulating layer and has at least one transmission line and a datum line. The datum line corresponds to the centerline of one of the grids and is separated from the transmission line by a second distance. The second distance can be quarters of the first distance. Since the characteristic impedance is controlled by varying the second distance, different second distance results in different characteristic impedance.

Abstract: A simulated SD memory card converter comprises an upper cover, a lower cover, an envelope, a plurality of conducting terminals and a detecting/retaining arm. The conducting terminals and the envelope are enclosed between the upper cover and the lower cover. The space between the combined upper and lower covers further includes a receptacle for the insertion of a Trans Flash memory card, whose opening is located at the front end of the converter. The rear edge of the lower cover is provided with a deficit corner and a row of holes connected to the wide ends of the conducting terminals. The narrow ends of the conducting terminals are shrunk toward the front edge of the lower cover and folded upright at the tips thereof. The envelope confines the middle section of the conducting terminals and is retained in the mid-rear portion of the converter.

Abstract: A simulated Mini SD memory card converter comprises an upper cover, a conducting member and a lower cover. The upper cover and the lower cover are engaged to form a combined structure resembling a Mini SD memory card, which structure has a main opening at a front end thereof and an insertion space therein for housing a Trans Flash memory card. A plurality of conducting terminals is enclosed in the lower cover. The rear end of said lower cover is further provided with a second opening corresponding to a terminal of the conducting member, whereby a front terminal of each of the conducting terminals is connected to the conducting member, and the conducting member further includes wirings to the second opening.

Abstract: A counterfeit money detecting barcode scanner comprising a body with a scan light source, a lens and a CCD or CMOS image sensor inside. When the scan light source aims at and injects light beam to a barcode label, the reflected barcode label image is received and converted to digital signals by the CCD or CMOS image sensor; the digital signals will be stored or transmitted out for further usage. An ultraviolet light source is in the light injection or the reflected light direction; an independent switch can turn the ultraviolet light source on or off to detect counterfeit money.
