Various x-y input devices are disclosed that are adapted to allow a user to hold and operate the input device with a stress-reducing, open grip posture with the thumb pointing forward and on top of the device. One preferred embodiment discloses an input device for a computer comprising an x-y input sensor (such as a touchpad) positioned perpendicular to the thumb such that the user provides input with the thumb tip by using pivotal movement of the thumb. Various stress-reducing zero force touch switches are disclosed including zero force touch switches that can be adjusted to accommodate variations in user finger length. The mode of x-y cursor control can be altered through the use of x-y input sensor perimeter inputs. One preferred embodiment discloses a thumb actuated scroll select touch switch that alters the response to actuation of the finger actuated zero force touch switches from mouse button input to scroll wheel input. A unique fin-shaped feature of one preferred embodiment stabilizes the device within the relaxed hand and adapts the device to fit a range of user hand sizes.

There is a digit splint for treating injury to a finger 12. The splint includes a plurality of position adjustable segments 1A, 1B, 1C arranged end-to-end on a connecting linkage 2, 3 to form an elongated support securable along the dorsal or ventral surfaces of the finger. The segments are slidable on the linkage relative to one another in the longitudinal direction so that the splint can be adjusted to suit different finger lengths. The connecting linkage is deformable to put the finger in flexion for a phalangeal fracture or extension for a mallet finger injury.

Operating a game controller to identify a user by receiving touch pad input from at least one touch sensitive pad of the game controller that has a plurality of touch sensitive elements. The touch pad input corresponds to the user's touch of at least some of the plurality of touch sensitive elements. The touch pad input is at least partially processed by processing circuitry of the game controller and transmitted to a game console via a communications interface of the game controller for processing of the at least partially processed touch pad input to identify the user via pattern recognition.

An electro-acoustic transducer for a component operating with surface waves, in particular for a surface wave filter, in which, to suppress interfering excitation ensuing in the gap region adjacent an end of a finger, a variation of the gaps is implemented with regard to at least one feature selected from transversal arrangement, size and shape. Due to the slight dimension change of the position of the gap in comparison to the finger length, the desired primary excitation in the transducer remains approximately unchanged, however the interfering excitation is displaced or divided, and made ineffectual.

The invention provides a functional rehabilitation robot based on flexible cable-driven hand movement. The functional rehabilitation robot is composed of a driving unit and an execution unit connected with the driving unit; the execution unit comprises a metacarpophalangeal joint unit module for driving the finger root joints to move, a proximal interphalangeal joint unit module for driving the finger middle joints to move and a distal interphalangeal joint unit module for driving the finger end joints to move, and the driving unit comprises three sets of driving modules which work independently, have the completely same structure and correspondingly drive the metacarpophalangeal joint unit module, the proximal interphalangeal joint unit module and the distal interphalangeal joint unit module. According to the functional rehabilitation robot, not only can the three freedom degrees of the fingers except for the thumb and the movement angles of all the joints be met, but also a serial elastic driver is introduced, and therefore precise control over the joint moment is guaranteed; in addition, most parts are made through 3D printing, the weight of the acting fingers is greatly decreased on the premise that the strength is guaranteed; furthermore, the robot adapts to the individual difference of the finger length within a certain range.

The invention discloses a finger grasp rehabilitation training device. The finger grasp rehabilitation training device is characterized in that a detection device comprises a torque sensor and an encoder, wherein the torque sensor is used for detecting torque positions when fingers are subjected to grasp training, and the encoder is mounted on a motor and used for detecting torque when the fingers are subjected to grasp training. The finger grasp rehabilitation training device has the advantages that the finger grasp rehabilitation training device integrates rehabilitation training with patient movement state detection and is capable of evaluating rehabilitation training progress and rehabilitation training effects effectively; active training and passive training of finger grasp can be achieved; different finger lengths are compensated by different finger sliders to enable the tail end of a finger mechanism to be on the same plane, and accordingly mechanism design is simplified; by moving in sliding grooves with different inclination angles, the fingers can be closed during grasp and can be spread during spreading; the finger grasp rehabilitation training device is capable of simulating normal grasping and spreading movements of a human body most effectively to improve rehabilitation effects, thereby being applicable to hemiplegia patients in the early, intermediate and advanced stages and being high in applicability.

The invention discloses finger movement function rehabilitation apparatus driven by shape memory alloy wires, and belongs to the field of finger rehabilitation. The apparatus is composed of the shapememory alloy wires, ropes, an alloy wire connecting terminal, an inner-layer fabric, an outer-layer fabric, range extending mechanism supports, rings, and other parts. When the shape memory alloy wires are powered on, the temperature rises under the current heat effect to generate phase changes, the contraction is generated, then the ropes are pulled, and fingers are driven to bend and stretch. The fabrics on the inner layer and the outer layer have good elasticity, and the tightness degree of the whole fabric can be adjusted in cooperation with Velcro on an arm. In addition, a proper amount of silica gel is placed between each layer of fabric to improve the wearing comfort of the apparatus. A length of the alloy wires extending out of the connecting terminal at the tail end is adjusted toadapt to different finger lengths, so that the requirement of ergonomics is better met. The three Velcro are located on the wrist, the forearm close to the elbow, and the big arm close to the elbow respectively. The three Velcro can enable the rehabilitation apparatus to be better attached to the shape of the arm of the human body, so that range extending mechanisms more efficiently use the phasechange contraction of the SMA wires to drive the fingers to bend and stretch, and thereby the better rehabilitation effect is achieved.
