A stent is constructed using interconnected links having micro-mechanical latching mechanisms. The micro-mechanical latching elements allow relative rotational movement of interconnected links in one rotational direction but restrict relative rotational movement of the two links in the opposite direction. The micro-mechanical latch surface features are formed using microelectronic mechanical systems (MEMS) manufacturing methods. The male surface of the latching components contains an array of ridges or protrusions, and the receiving surface contains a matching array of recesses. The array of ridges or protrusions and the corresponding recesses have uniformly dissimilar slopes that result in a substantially greater frictional force in one direction than in the opposite direction. The separation distance between the two surfaces is such that the male latch surface is engaged with the receiving surface recesses in the low stress “locked” state, preventing motion in the undesired direction. Each male ridge or protrusion can be underlined by a void that promotes elastic deflection when sliding in the desired direction and recovery into the ‘locked’ state when aligned with the recesses.

The present invention relates to an aerodynamic drag reducing system for land vehicles, in particular semi-tractor trailers. The drag reducing system includes a selectively removable frame and a drag reduction member. The selectively removable frame can adapt to conform to at least one of the width or height of the land vehicle, and can be secured thereto by a securement assembly. In one embodiment, the drag reducing system can be folded and collapsed for compact storage. The drag reducing system can be easily and quickly secured to the back end of a semi-tractor trailer without tools and without requiring that any permanent modifications be made to the trailer. In one embodiment, drag reducing system includes a hinge joint assembly to facilitate installation, removal, and repositioning of drag reducing system.

A walker apparatus comprised of a first front support leg assembly, a second front support leg assembly, a first sliding joint, a second sliding joint, a central hinge joint, a first rear support leg assembly, a second rear support leg assembly, a first support member, a second support member, a front leg collapsing assembly, and a rear leg collapsing assembly. The walker apparatus is adapted to be is collapsed to a compact shape in a continuous collapsing motion.

The present invention provides a stand hinge for an electronic device, which is capable of standing an electronic device at different angles and positions. The present invention further provides an electronic device equipped with the same. The stand hinge of the present invention includes: a connecting member hinge-jointed to an electronic device to rotate in a first direction; and a supporting member for supporting the electronic device against a surface, the supporting member being hinge-jointed to the connecting member to rotate in a second direction different from the first direction.

The present utility model disclosed a main support frame, which has two bushings each set on the right and left side of said main support frame respectively; two supporting pipes, each inserted in one of the bushings of the main support frame; two P-shaped armrests, each connects with one of the supporting pipes; two pairs of front-wheel assembly and rear wheel assembly, each pair of front-wheel assembly and rear wheel assembly is connected with the main support frame; and a seat component comprising a seat body and a folding mechanism, said seat component can be folded in the middle and is set between the left side and right side of main support frame. Said folding mechanism consists of a first branch pipe and a second branch pipe, which hinge joint with each other in the middle, one end of the first branch pipe and the second branch pipe hinge joint with the left side and right side of the main support frame respectively, the other end connect with the two ends of said seat body respectively. The improvements of the magic rollator are that: the structure is simple, it is easy to be folded and the folded volume of it is small, it stands stably and is convenient for storing and transporting, the height of it is adjustable to meet the requirements of different users; the components of it are easy to be processed, the cost is low, meanwhile the components are assembled by bushing parts and jointed together by elastic blocking joints, it is unnecessary to use special tool to mount or dismount it, so it is suitable for customers to use.

A brace for supporting the knee of the wearer. The brace has an adjustable support mechanism for accommodating a variety of leg shapes. The hinge portion of the brace is adjustable so that there is proper balanced support on opposite sides of the knee. Furthermore, the brace is universal in applicability and may be used on either the right or left leg.

An external fixation frame for correcting a bone deformity includes a first fixation ring and a second fixation ring. A posterior adjustable length strut couples a posterior portion of the first fixation ring to a posterior portion of the second fixation ring and has universal joint. Medial and lateral adjustable length struts couples medial and lateral portions of the first fixation ring to medial and lateral portions of the second fixation ring respectively, each of the medial and lateral adjustable length struts including a constrained hinge joint. The fixation frame also includes a half ring hingedly coupled to the second fixation ring, and an anterior adjustable length strut coupling an anterior portion of the first fixation ring to the half ring.

The present invention relates to a hair iron adapted to reduce hair damage, strengthen hair and facilitate hair styling by blowing air toward the hair. The hair iron of the present invention is further adapted to provide hair with anions or moisture during hair styling. The hair iron includes a pair of cases hinge-jointed at each one end and being freely opened or closed, wherein each case has a heater plate for generating heat at the other end. A fan assembly for blowing air is coupled to the one end of one of the cases. An air passage through which the blown air is passed is formed inside the hair iron. An anion generator is located in the fan assembly, thereby mixing the anions with the air being transferred. Means for providing moisture is disposed adjacent to the heater plate and means for supplying the moisture-providing means with water is received in the recess formed in lower side of the case. Further, the present invention relates to a hair iron constructed without a power cord so as to be utilized without any spatial restriction while possessing all the functions of the hair iron.
