  • Patent number: 10183404
    Abstract: Linear motion devices that may include a band configured to be helically interlinked into a tube, where the band includes a plurality of protrusions and a plurality of recesses that engage the plurality of protrusions to link the band with itself. The linear motion devices also include a sliding guide configured to link and unlink the band, where the sliding guide includes an outer layer, an inner layer, and a ramp between the outer and inner layers having a helical incline to support a bottom portion of the band. The linear motion devices include a driving mechanism that is in contact with the band, the driving mechanism configured to move the band through the sliding guide up the helical incline to link the band, thereby extending the tube, and to move the band through the sliding guide down the helical incline to unlink the band, thereby retracting the tube.

  • Publication number: 20180304477
    Abstract: A joint attachment system for a reconfigurable truss includes a first joint attachment having a first pivot axis and a second joint attachment having a second pivot axis. The first joint attachment and second joint attachment form a concentric spherical joint linkage when attached to a first body member and a second body member, respectively. The first pivot axis of the first joint attachment intersects the second pivot axis of the second joint attachment at a single point X which defines a center of the concentric spherical joint linkage. The concentric spherical joint linkage is configured to allow the addition of one or more joint attachments and body members to the truss node. In addition, the concentric spherical joint linkage is configured to allow the removal of one or more joint attachments and body members from the truss node.

  • Patent number: 8464978
    Abstract: A rotorcraft with two counter-rotating rotors and method for inertially controlling the rotorcraft. The rotorcraft includes a hinged frame configured such that at least one inter-rotor angle of the two counter-rotating rotors is controlled by at least one actuated hinge of the hinged frame and the rotational axes of the two counter-rotating rotors are substantially collinear when the actuated hinge is in a fully open position. The sum of the magnitudes of torque applied to the two counter-rotating rotors is varied to control the lift of the rotorcraft. The difference of the magnitudes of torque applied to the two counter-rotating rotors is varied to control the yaw of the rotorcraft. The at least one inter-rotor angle is varied using the at least one actuated hinge to control the pitch and/or roll of the rotorcraft.

  • Publication number: 20080055248
    Abstract: A man-machine interface which provides tactile feedback to various sensing body parts is disclosed. The device employs one or more vibrotactile units, where each unit comprises a mass and a mass-moving actuator. As the mass is accelerated by the mass-moving actuator, the entire vibrotactile unit vibrates. Thus, the vibrotactile unit transmits a vibratory stimulus to the sensing body part to which it is affixed. The vibrotactile unit may be used in conjunction with a spatial placement sensing device which measures the spatial placement of a measured body part. A computing device uses the spatial placement of the measured body part to determine the desired vibratory stimulus to be provided by the vibrotactile unit. In this manner, the computing device may control the level of vibratory feedback perceived by the corresponding sensing body part in response to the motion of the measured body part. The sensing body part and the measured body part may be separate or the same body part.

  • Publication number: 20060131907
    Abstract: A robotic device may include a plurality of concatenated assemblies, a tendon slidably connected to the plurality of concatenated assemblies, and an actuator that moves the tendon. Each assembly of the concatenated plurality may include a joining member that neighbors an adjacent assembly, a linkage that may fixedly connect to the joining member and may pivotably connect to the adjacent assembly, and an appendage that may extend from the joining member to a length. The appendage may include a connector through which the tendon may be connected to slide through. The connector may be adjustably disposable along the length of the appendage to a specified position thereon. The appendage may extend in a direction at a specified angle relative to the linkage.

  • Publication number: 20050184543
    Abstract: A transport apparatus for transporting materials or objects on substantially vertical structures for installation, deployment, inspection and repair purposes includes gripping mechanisms having a conformable gripping portion. The gripping mechanisms are separated by links, which are mutually attached to each other to permit angular rotation of the links relative to each other about a pivot point. A latching mechanism provides the capability for the gripping portion to be opened as well as secured for operation.

  • Publication number: 20050179198
    Abstract: A flexible media transport system includes a director element having articulating tips that provide access to selected media paths. The director element(s) can be incorporated into a director module. Multiple director modules can then be combined into a highly flexible and reconfigurable media transport system. By implementing the joints between the articulating tips and the body of the director element such that a continuous surface is provided in the path of the flexible media, stubbing of the moving media can be avoided. The continuous-surface joint interface can be provided via flexible skins, monolithic articulating tip-director element structures, and preconfigured resilient plate structures, among others.

  • Patent number: 6104379
    Abstract: A man-machine interface device is provided which employs rigid links interconnected by measured revolute joints to provide the position of a hand relative to a reference location, such as a desk, keyboard or chair. By proper selection of kinematic structure, and by placing one of the joints near the elbow and extending one of the links along the line of the forearm, translation of the joint-link structure is minimized, hence the undesirable perception of friction and inertia are also minimized. When Hall-Effect sensors are used as the revolute joint goniometers, the permanent magnets of neighboring joints are placed in the same link so the effects of magnetic field interference can be calibrated out. A hand-sensing joint-link device as described herein can produce data which is more noise free, at a higher sample rate, with less latency and more robust that competing electromagnetic, optical and ultrasonic sensing technologies, without adding much encumbrance.
