Patent number: 10980697Abstract: 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.Type: GrantFiled: April 27, 2016Date of Patent: April 20, 2021Assignee: BIOSERVO TECHNOLOGIES AKTIEBOLAGInventors: Martin Oskar Gustaf Ewaldsson, Johan Ingvast

Patent number: 10786022Abstract: 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.Type: GrantFiled: April 27, 2016Date of Patent: September 29, 2020Assignee: BIOSERVO TECHNOLOGIES AKTIEBOLAGInventors: Johan Ingvast, Martin Oskar Gustaf Ewaldsson

Publication number: 20180296421Abstract: 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.Type: ApplicationFiled: April 27, 2016Publication date: October 18, 2018Inventors: Martin Oskar Gustaf Ewaldsson, Johan Ingvast
