Abstract: A hinge assembly includes a first and a second set of friction elements engaged each other by an applied force perpendicular to the friction elements. The first and the second set of friction elements are capable of rotational movement about a cylindrical element that passes through each of the friction elements. Also, the first set of friction elements is capable of movement relative to the second set of friction elements. However, the first set friction elements can remain in a fixed position based upon the applied force, until an external force overcomes the applied. During rotation of the first set of friction elements about the cylindrical element, the frictional engagement that controls the position of the first set of friction elements is based primarily on engagement between the friction elements, as opposed to engagement, if any, between the friction elements and the cylindrical element.

Abstract: The present disclosure relates generally to connectors such as audio and data connectors and in particular to low profile audio connectors that can be used in place of standard audio and data connectors currently used. The plug connector has a reduced plug length and thickness, an intuitive insertion orientation and a smooth, consistent feel when inserted and extracted from its corresponding receptacle connector. The plug connector may be characterized by a flat tip portion at its distal end, a base portion near its proximal end, a shell coupled at the base portion and a plurality of external contacts.

Abstract: A dual orientation plug connector having a connector tab with first and second major opposing sides and a plurality of electrical contacts carried by the connector tab. The plurality of contacts may include a first set of external contacts formed at the first major side and a second set of external contacts formed at the second major side. The first plurality of contacts may be symmetrically spaced with the second plurality of contacts and the connector tab may be shaped to have 180 degree symmetry so that it can be inserted and operatively coupled to a corresponding receptacle connector in either of two insertion orientations. A receptacle connector corresponding to the plug connector.

Abstract: A robotic joint configured as a 3-axis joint. The joint includes an input roll assembly and a pitch-output roll assembly. The pitch-output roll assembly includes: a housing; a differential mechanism including left and right input gears, an output gear, a cross element interconnecting the gears, and a clevis supporting the gears and the cross element; a left four-bar linkage coupled to the left input gear; a right four-bar linkage coupled to the right input gear; and first and second linear actuators connected to the left and right four-bar linkages. The first and second linear actuators selectively drive the left and right input gears to rotate the output gear about an output roll axis and to rotate the cross element about a pitch axis passing through the cross element and input gears. A linear actuator in the input roll assembly rotates the pitch-output roll housing about an input roll axis.

Abstract: An input device includes a positioning element and a spring member. The positioning element comprises a generally disc shaped member. The spring member is a generally annular shaped spring member that is generally planar and that defines a generally serpentine pattern. The spring member is positioned laterally outward relative to the positioning element and is configured to exert a biasing force radially inwardly toward the positioning element.
