  • Patent number: 10682249
    Abstract: An exoskeleton (100) adapted to be coupled to a lower extremity of a person includes a thigh link (102), a shank link (104) and a knee joint (106) allowing flexion and extension between the thigh and shank links (102, 104). A torque generator (156) connected to the knee joint (106) includes a wrap spring (110) having a first end (112) coupled to the thigh link (102), and a second end (118) coupled to an electric actuator (116) capable of selectively positioning the second end (118) of the wrap spring (110). A controller (120) causes the electric actuator (116) to position the wrap spring (110) to provide a selective torque between the thigh and shank links (102, 104) based on a signal (212, 214, 216) produced by a sensor (164, 166, 168).

  • Publication number: 20190327222
    Abstract: An embodiment of the invention may include a method, computer program product and system for secure authentication within a communication protocol session. The embodiment may include retrieving, by a client computer of the TLS session, a challenge string associated with the TLS session. The embodiment may include generating, by the client computer, a first digest based on the challenge string and authentication information of a user of the client computer. The embodiment may include sending, by the client computer, the first digest to a server of the TLS session. The retrieving, generating and sending, by the client computer, are carried out after the TLS session has been established between the client computer and the server.

  • Publication number: 20190231574
    Abstract: An exoskeleton includes two torque generators, thigh links, and a supporting trunk rotatably coupled to the thigh links. When a wearer bends forward in the sagittal plane such that the supporting trunk extends beyond a predetermined angle A with respect to vertical, at least one of the torque generators imposes a resisting torque between the supporting trunk and a corresponding thigh link, thus imposing a force onto a wearer's trunk and thighs to aid in supporting the wearer in a bent position. The exoskeleton may include an active or passive means for actuating the torque generators. When the supporting trunk does not extend beyond the predetermined angle A, the torque generators do not impose resisting torques between the supporting trunk and thigh links during the entire range of motion of the thigh links, thus enabling a wearer to walk, run, and sit without constraint while in a substantially upright position.

  • Publication number: 20190216630
    Abstract: A trunk supporting exoskeleton comprises: a supporting trunk; thigh links configured to move in unison with a wearer's thighs; and first and second torque generators located on both left and right halves of the wearer substantially close to the wearer's hip. The torque generators couple the supporting trunk to the thigh links, and generate torque between the thigh links and the supporting trunk. When the wearer bends forward such that a predetermined portion of the supporting trunk passes beyond a predetermined angle from vertical, a torque generator(s) imposes a resisting torque between the supporting trunk and the thigh link(s), causing the supporting trunk to impose a force against the wearer's trunk, and the thigh link(s) to impose a force onto the wearer's thigh. When the predetermined portion does not pass beyond the predetermined angle, the torque generators impose no resisting torques between said supporting trunk and respective thigh links.

  • Publication number: 20180250187
    Abstract: A leg support exoskeleton is strapped on as wearable device to support its user during squatting. The exoskeleton includes a knee joint connected to a first line and a second link, which is configured to allow flexion and extension motion between the first link and the second link. A force generator has a first end that is rotatably connected to the first link. A constraining mechanism is connected to the second link and has at least two operational positions. In a first operational position, the second end of the force generator engages the constraining mechanism, where the first link and the second link flex relative to each other. In a second operational position, the second end of the force generator does not engage the constraining mechanism; the first link and the second link are free to flex and extend relative to each other.
