Glove virtual keyboard for baseless typing
InactiveUS20040001097A1Efficiently and quickly input dataInput/output for user-computer interactionCathode-ray tube indicatorsContact padTyping
A data glove input device, serving as a virtual keyboard and enabling ten-finger-typing, has two palm bodies with glove fingers. A tilt sensor is mounted on the middle phalanx of each respective glove finger. It is used to detect the falling in one of multiple tilt angle ranges of the phalanx and to select a specific item from items in a particular column. The same tilt sensor for item selecting can also be used to validate a selection by detecting a tilt angle peak pulse. Multiple contact pads and multiple switch buttons are mounted on the lateral sides of glove fingers except the thumbs, and each of them, which is able to be touched by the thumb, is to switch the same signal selected by a tilt angle or a finger to represent another different item. Accordingly, the data glove can be finger tip uncovered and allows baseless virtual typing.

Interphalangeal Joint Implant Methods and Apparatus
ActiveUS20130325138A1Decreasing eliminating incidenceSimple procedureFinger jointsInternal osteosythesisSacroiliac jointMiddle phalanx
A method and apparatus for correcting malformed joints, in particular the “hammer toe” contraction of the proximal interphalangeal joint. The disclosure comprises a two-component implant: a proximal phalanx component and a middle phalanx component. An endosseous stem on each component is inserted axially into the end of a respective host bone and, after insertion, the components are attached. The attached components are held together in various ways, for example a detent arm / aperture mechanism. Each component can be cannulated to allow for the passage of a kirschner wire, if necessary, to stabilize adjacent joints such as the proximal interphalangeal joint. The bones of the treated joint can be set to form a desired angle by adjusting the angle formed by the corresponding endosseous stems.

Hand-shaped manipulator
The invention discloses a hand-shaped manipulator which mainly comprises a hand, a wrist and a front arm, wherein the hand comprises a palm, A-type fingers, B-type fingers and a thumb. Grabbing is achieved through the A-type fingers and the thumb, and the B-type fingers are auxiliary fingers. Each A-type middle phalanx, each A-type proximal phalanx and each A-type base phalanx are controlled independently and respectively through four tendon ropes. Due to the fact that the B-type fingers have auxiliary functions, an underactuation control mode is adopted, and active control is performed on each middle phalanx through two tendon ropes. A thumb distal phalanx, a thumb middle phalanx and a thumb proximal phalanx are controlled independently through five tendon ropes. A wrist joint is matched with a spherical hinge through a cardan joint, and pitching and sideway moving can be achieved by means of telescopic movement of a pull rod. Parts of the manipulator can be manufactured easily, cost is low, and the manipulator has multiple functions achieved by a hand of a human, such as capturing, holding, grabbing, switch turning and the like. The hand-shaped manipulator is small in size, light in weight, flexible and accurate in operation, low in cost and wide in application prospect.
