A cam-actuated connection device joins rail mounting members of a photovoltaic panel array. The connection device slides within channels of mounting members until the members are in a properly positioned grid. When in position, the connection device is rotated to lock the mounting members in a rigid grid network. The connecting device can be subsequently loosened, repositioned and locked into position. The rail-mounting members create a grid for installation of multiple PV panels. The mounting rail allows the unit to remain relatively compact in nature but still covers a wide range of PV panel thicknesses. The rail system has a hinged connection with the mounting rail that allows an installer to assemble the module in a near perpendicular fashion to the mounting rail, make the required electrical connections and then lower the PV module into its working position. The unit is then locked into its working position.

An automated tightening shoe with crisscrossed laces and a tightening mechanism which operates in one direction to cause automatic tightening of the crisscrossed laces to tighten the shoe about a wearer's foot, and which can be released easily so that the shoe can be removed from the wearer's foot.

An automated tightening shoe with crisscrossed laces and a tightening mechanism which operates in one direction to cause automatic tightening of the crisscrossed laces to tighten the shoe about a wearer's foot, and which can be released easily so that the shoe can be removed from the wearer's foot.

An automated tightening shoe with a single crisscrossed laces or closure panel and a tightening mechanism which operates in one direction to cause automatic tightening of the crisscrossed laces or closure panel to tighten the shoe about a wearer's foot, and which can be released easily so that the shoe can be removed from the wearer's foot. An actuating wheel partially projecting from the rear sole of the shoe provides a convenient and reliable actuating means for movement of the automated tightening mechanism in the tightening direction.

A microprobe array structure with self-stabilization capability and a method for manufacturing the same are proposed. The microprobe array structure is used to sense various biopotential signals, and is characterized in that the etching parameters are controlled during etching to manufacture a microprobe structure with a reduced bottom cross section so that the microprobe can be firmly stabilized in the skin tissue. Moreover, a conducting layer is formed on the microprobe to sense signals. A design of electric isolation between microprobes is also proposed. The microprobe array can therefore be used for the measurement of various biopotential signals, and can also be used as a stimulus.

In the present invention, a biodegradable bone graft is disclosed, which includes: a scaffold made of a biodegradable material; and a collagen-embedding matrix portion which completely encompasses the scaffold. The above-mentioned bone graft can increase the micro-porosity of the scaffold to enable cells to grow adhesively thereon. Compared with the scaffold only, the above-mentioned bone graft has high hydrophilicity. Hence, the bone graft of the present invention can efficiently retain tissue fluid, cell growth factors, blood and/or bone marrow which are mixed with the bone graft beforehand to achieve osteoinduction. Furthermore, the collagen-embedding matrix portion can also serve as a carrier to encompass other bone graft materials and drug molecules. The present invention also relates to a method for manufacturing the above-mentioned bone graft.

An automated tightening shoe is provided where a tightening mechanism operates to cause automatic tightening of the shoe laces about a wearer's foot and which releases the laces to allow loosening of the shoe. The shoe laces travel to the interior of the tightening mechanism located at the heel whereat the laces are operatively associated in a tightening or a loosening direction with the tightening mechanism. The tightening shoe further has a locking mechanism for locking said at least one lace in a tightened condition and a release mechanism for unlocking the locking mechanism and releasing the shoe laces. The release mechanism includes a lever arm which projects rearwardly from the rear of said shoe. Depression upon the lever arm causes the locking mechanism to unlock and release the shoe laces from being in a tightened condition.

An improved rotatable battery cable clamp connector is designed for use with applying pressure to legs of the clamp intermediate the cable section and post section of the clamp. Self-lubricating and non-corrosive materials are also used to advantage in the manufacture of the connector.

A buckle having a male portion and a female portion. The male portion has two sidewalls, first and second retaining bars and at least one locking arm. There is a slidable strap gripping bar disposed adjacent the first strap retaining bar. The strap gripping bar is adapted to slide between a release position and a gripping position. The female portion comprises a hollow body with an open end and at least one locking slot for receiving the locking arm. When the male portion is inserted into the female portion, the locking arm locks into the locking slot and the female portion pushes the strap gripping bar into a gripping position, which grips a strap threaded through the retaining bars, and prevents the strap from slipping. When the male portion is released from the female portion, the strap gripping bar slides into the release position and allows adjustment of the strap.

An exemplary joining structure, used for insert-molded covers, includes a metallic portion (131), a plastic portion (132) integrally formed with the metallic portion, and an adhesive film (133) formed between the metallic portion and the plastic portion. The metallic portion and the plastic portion are bonded together by the adhesive film. The present invention also relates an insert-molded cover (10) for electronic devices using the joining structure and a method for manufacturing the insert-molded cover for electronic devices.

A portable air pump includes a tubular body, a barrel, a piston mechanism, a head, and a dispensing head. Tubular body has upper cover having air inlet holes and sealed bottom cover. Barrel has air passage running through along its axis direction. Piston, having center hole and through hole, and check valve is in between second end of the barrel and piston. As tubular body is moved in relation to barrel away from the head, air is flown into tubular body through air inlet holes and to the bottom of tubular body through the through hole. Air can be prevented from flowing out from the center hole using check valve disc. As the tubular body is moved in relation to the barrel towards the head, air on the bottom of tubular body is flown into air passage of the barrel through center hole, and out from the head and the dispensing head.

The invention discloses a mechanical part die with die releasing conveniently conducted. The mechanical part die comprises an outer cylinder body and a die body. A drive motor is fixedly connected tothe center position of the top of the inner surface wall of the bottom of the outer cylinder body, and the top of the drive motor is in drive connection with the die body through an output shaft. Multiple arc angle protruding blocks are welded to the outer side of the die body at equal angles around the circle center of the die body. According to the mechanical part die, the arc angle protruding blocks are arranged on the outer side of the die body, steel balls are arranged on the inner surface wall of the outer cylinder body, the drive motor is used for driving the die body to rotate so thatthe arc angle protruding blocks can collide with the steel balls intermittently, a knocking vibration effect is generated, and a blank part can be loosened from the die body through the knocking vibration effect. In addition, a certain centrifuging effect can be generated in the rotating process of the die body, and the blank part can be more easily loosened from the die body through the centrifugal force. Furthermore, due to the arrangement of an MYT3-23 hydraulic thruster and an electromagnetic plate, the blank part can be easily taken out, the working difficulty is lowered, and the die releasing efficiency is improved.
