Abstract: A facial interface for a head-mounted display, which is to be worn on a head of a user, includes an upper portion and a lower portion. The upper portion engages an upper facial region above eyes of the user. The lower portion that engages a lower facial region below the eyes of the user. The lower portion has a lower shear compliance in that is greater than an upper shear compliance of the upper portion.

Abstract: A truly one-handed operable pipe wrench is provided which includes a handle having a first end and a second end, a fixed jaw disposed at the second end of the handle, and a rotatable jaw pivotally attached to the second end of the handle. The rotatable jaw includes a first engaging end and a second driven end. A lever arm is pivotally attached to the handle. The lever arm includes a handle portion and an actuating portion. When the lever arm rotates relative to the handle, the actuating portion is in contact with the second driven end of the rotatable jaw causing the rotatable jaw to rotate relative to the second end of the handle.

Abstract: A lever unit is provided with a start lever rotatably provided on a securing shaft, a ratchet mechanism that restricts a movement direction of the start lever to one direction, and a reset mechanism that releases the restriction on the movement direction by the ratchet mechanism, wherein the ratchet mechanism is provided with a rotation plate that rotates integrally with the start lever and on which multiple teeth are formed on an outer edge thereof, and multiple latch pieces having engaging portions that mesh with tooth depression portions between the teeth of the rotation plate, wherein the multiple latch pieces are set in an array along an outer edge of the rotation plate so that each time the rotation plate moves a single pitch portion of the teeth, the engaging portions of all of the latch pieces mesh alternately with one of the tooth depression portions.

Abstract: The present invention provides an assembly for controlling the rotational movement of a die wheel in packaging machinery and includes a first component operationally interconnected to both the die wheel and camshaft, and a second component physically connected to both the first component and the framework of the packaging machine wherein the second component is detachably mounted to the framework.

Abstract: A locking apparatus includes a handle, a hook and a handle magnetic device. The handle is pivotally connected to a cover of an electronic product. The hook has a first end pivotally connected to the handle and a second end with a locking part. The locking part is fastened to a base of the electronic product when the electronic product is locked. The handle magnetic device is located on a surface of the handle facing the cover of the electronic product for attracting a cover magnetic device of the cover of the electronic product after the locking part is fastened to the base of the electronic product. Furthermore, a folding electronic product with the locking apparatus is also disclosed in the specification.

Abstract: An automatically and smoothly continuously variable transmission, particularly for a bicycle, for transmitting input mechanical energy from a crank to the drive wheel. A ratchet, having an oscillatory, alternating motion member and a continuous rotary motion member, connected to the driven wheel, has a drive spring drivingly linked between the ratchet alternating member and the crank for driving the ratchet alternating member in one direction of motion. A return spring is linked to the ratchet alternating member for applying a return force upon the ratchet alternating member to return the alternating member in the opposite direction.

Abstract: A mounting apparatus allows easy adjustment of the holding position after the apparatus is mounted. The mounting mechanism presses against, at least, two points of a target portion, e.g., the head portion of the user, with at least one holding means (3), so as to detachably mount an apparatus (1) connected to the holding means (3) on the target portion. The holding means (3) includes a roller (10) of which the moving (rotating) direction is limited by a one-way clutch or the like, thereby allowing easy position adjustment after the apparatus is mounted.

Abstract: This invention relates a mounting apparatus, mounted at a predetermined portion, e.g., the head portion of the user, for holding an apparatus at a predetermined position and, more particularly, to a mounting mechanism which allows easy adjustment of the holding position after the apparatus is mounted.
