Abstract: A grip strengthening device having a finger portion for enhancing the grip by means of at least one artificial tendon arranged along at least one finger portion, wherein the finger portion comprises material along both sides and a tip, and possible along a dorsal side, the at least one artificial tendon is attached along both sides so that the artificial tendon may move, wherein the artificial tendon runs closer to a ventral side than the dorsal side of the finger portion, at least at positions corresponding to joints of a wearer's finger, the finger portion will transfer a force to provide a movement of the finger when the artificial tendon is retracted, wherein the artificial tendon runs in a detour towards or to a position in the middle between the dorsal and ventral side or closer to the dorsal side at a proximal portion of the finger portion.

Abstract: A twisted string transmission for converting a rotational motion to a linear motion is provided, comprising a motor (1) and a string (2) to be connectable to a load (3). The string (2) has a variable diameter along its length.

Abstract: A tendon actuated hand enhancer (1) having a force anchoring device (2), comprising a rigid band (8), circumventing more than half of a circumference, but is bendable in the circumferential direction. At least one pulling point (6) for at least one artificial tendon (3) is provided at the force anchoring device (2). The force anchoring device (2) is provided at the tendon actuated hand enhancer (1) at a position corresponding to carpal and proximal portion of metacarpal bones of a user's hand when the hand enhancer (1) is in use, and a pulling means (4) for pulling the at least one artificial tendon (3) is connected to the hand enhancer (1).

Abstract: Method when a user performs a work task, wherein the user wears and uses a wearable, actively controlled piece of force-assisting equipment (110) used to assist the user in the performing of the said work task, which force-assisting equipment (110) comprises a force-exerting means (112,113) for assisting the user in applying a particular force and/or for performing movements of a particular type, and a sensor means (115) for sensing a force applied by the user, wherein an assisting force exerted by said force-exerting means (112,113) is feedback-controlled based on an instantaneous measurement value from the sensor means (115). The invention is characterised in that the method comprises the steps of during the performance of said work task, measuring said measurement value using the sensor means (115) for use in said feedback control; and using the measurement value to automatically calculate an actual ergonomic risk or load value for the performed work task using the said force-assisting equipment (110).

Abstract: A finger glove liner (2) comprising at least one finger portion (1), for arrangement inside an outer finger glove, making up a grip strengthening finger glove (3) is provided. The finger glove liner (2) is made of a stretchable material (4) in order to suit more than one size of hands, wherein at least one patch (5) of material, which has attached thereto at least an artificial tendon (9), is arranged at the outside of the finger glove liner (2).

Abstract: Provided is a technique for attaching an artificial tendon to a support device having a supporting material as well as a product formed by the technique. The artificial tendon is provided for flexing or extending a joint of a body, when applied at the joint of the body, by way of pulling the artificial tendon along its lengthwise direction. The artificial tendon is attached to the support device by stitching across the tendon with a thread on the supporting material of the support device, which forms a tunnel for the artificial tendon between the supporting material and the stitching. The artificial tendon is able to travel in the tunnel. The tunnel formed by this technique is positioned on the surface of the supporting material of the support device.

Abstract: Control system (200) for a strengthening glove (100) with fingers (101-105), comprising a force detecting sensor means (210) for detecting, at different measurement locations (211-218) on the palm side (106) of said glove fingers, a respective force between a finger (11-15) and a contact surface, further arranged to impart a force to respective glove fingers, bending them towards a gripping position, further arranged to read measurement values from the strengthening feedback loop based upon the measurement values. The invention is characterised in that a predetermined pattern is detected, comprising certain measurement values, in that, when the said pattern is not detected and the actuating means are controlled according to a first program, and further when the said pattern is detected, they are controlled according to a second program, which first and second programs are different.

Abstract: A method of attaching an artificial tendon (1) at a support device having a supporting material (2), the artificial tendon is provided for flexing or extending a joint (3) by means of pulling the tendon, stitching (5) across the tendon with a low friction thread, forming a tunnel (12) for the tendon between the supporting material and the stitching, in which the tendon may travel. A tunnel for an artificial tendon to be able to travel in, positioned at a surface of a supporting material of a supporting device, formed by the supporting material and a stitching across the tendon, the stitching comprising a low friction thread. A strengthening glove having artificial tendons for flexing or extending at least one finger, characterised in that the tendons run in a tunnel formed by the supporting material and a stitching across the tendon.
