Abstract: A wrench with a quick rotatable driving head includes a handle, a driving head and a quick-disengaging unit. The quick-disengaging unit is composed of a fixing member secured with the driving head, an operating member inserted through the handle and fitted around the fixing member, and a restraining element transversely provided between the fixing member and the operating member and the handle. The handle and the driving head can be separated by the quick-disengaging unit so that the driving head, with the quick-disengaging unit acting as a pivot, can quickly screw or unscrew a thread locking member, and the operating member can be restrictedly positioned on the fixing member by the restraining element, able to prevent the handle and the driving head from separating.

Abstract: A multi-function socket wrench includes a driving head, a handle, a pivot rod, a first elastic limit unit and a second elastic limit unit. The driving head is pivotally connected with the pivot rod. The driving head can be slidably moved on the handle through the pivot rod and the first elastic limit unit. The driving head and the handle are secured through the second elastic limit unit. The handle and the driving head of the multi-function socket wrench can be turned free as the demand of the user to be a T-shaped socket wrench or operated horizontally.

Abstract: A prosthetic finger that is able to provide independent natural movement to mimic a real finger. The present invention utilizes unique connections to provide users with natural movement and restore their ability to perform activities that require the full dexterity of their hands. Additionally, the present invention also allows users to interact with touch screens that normally would not work due to the insulating properties of other traditional prosthetic fingers.

Abstract: The present invention relates to an automatic testing apparatus, which comprises a device under test and a testing module. The device under test has a testing program and includes a plurality of functional modules. The testing module is coupled to the device under test. The device under test executes a testing program and communicates with the testing module so that the testing module can test the plurality of functional modules of the device under test. By adopting automatic testing, no tester is needed for performing testing. Thereby, the personnel cost can be reduced and the total testing time can be shortened.

Abstract: An electromagnetic pulse protection circuit having wave filtering functions, composed of an inductor free slow response protection circuit and a fast response protection circuit, and a filter is series-connected on a signal transmission route, and is utilized to provide impedance in effectively preventing electromagnetic pulses caused by lightning (LS) or other electronic weapon (NEMP, HEMP, PEMP) interferences. In addition, it is capable of suppressing electromagnetic pulses at specific frequencies, thus, raising the capability of electronic elements in resisting against electromagnetic pulses. Furthermore, said filter is made of high-temperature-super-conduction (HTSC) material, so that when said HTSC material of said filter is subject to a sudden infusion or invasion of said electromagnetic pulses, it is switched to a high impedance state in a very short period of time in effectively restricting currents passing through said filter, hereby avoiding the damages of a communication system.

Abstract: The present invention relates to an ultra thin copper foil with a very low profile copper foil as a carrier, comprising a carrier foil a release layer and an ultra thin copper foil. The copper foil with the Very Low Profile, smooth on both sides (i.e. VLP copper foil) is used as the carrier foil, the said very low profile copper foil for supporting the ultra thin copper foil can bring advantages of no pinhole, excellent thickness uniformity and low surface roughness. The impact of a release layer on the bond strength between the carrier foil and the ultra thin copper foil is very significant, the release layer is composed of a quaternary metal alloy with peelability.

Abstract: An internally illuminated footwear has a light source shining into a translucent component. Boundary sections are created in the translucent component and are arranged to create various visuals, such as designs and logos. The boundary sections are formed by cavities which cut into the translucent component. Abrasive surfaces may be added to the cavities, or replace the cavities and be added to the surface of the translucent component. The cavities may be filled with a boundary material. Bubbles can be formed within the boundary sections and the translucent component. Light waves originate at the light source and travel through the translucent component. Due to different refractive indices, a light wave will be refracted as it encounters cavities in the boundary sections. The refracting light wave will then appear to originate at the cavities. In this manner, the cavities will appear to have their own individual illuminating source.
