A virtual or augmented reality headset is provided having a frame, a pair of virtual or augmented reality eyepieces, and an interpupillary distance adjustment mechanism. The frame includes opposing arm members, a bridge positioned intermediate the opposing arm members, and one or more linear rails. The adjustment mechanism is coupled to the virtual or augmented reality eyepieces and operable to simultaneously move the eyepieces in adjustment directions aligned with the plurality of linear rails to adjust the interpupillary distance of the eyepieces.

A dual function, inboard barrier / bridgeplate assembly for wheelchair lifts having a stowable platform, the barrier being pivotably secured to the inboard end of the lift platform, which barrier is actuated by a link to variously raise the barrier' to a safety position and lower it to a bridging position in accordance with the position of the platform. The dual function barrier / bridgeplate system is particularly useful in combination with a parallelogram type lift employing an articulated lever assembly having a sliding block for leveraging the platform from a horizontal transfer orientation to a vertical, or over-vertical stowage position. There is disclosed a barrier assembly in which a spring assist system comprising a gas spring acting on one member of the articulated lever assembly and a lever arm linking a second arm of the articulated lever assembly to the barrier co-operate to actuate the barrier from a raised position when the platform is away from the transfer level and a lowered position to act as a bridge plate at the transfer level. A telescoping push arm is included which actuates the barrier by means of a pivoted link which rotates the barrier in response to the telescoping motion of the push arm. A safety interlock and load detecting system may be employed to prevent the platform from moving to the stowed position when a load greater than a predetermined weight is on the platform. An anti-free fall mechanism is disclosed comprising a pin in the slide block which engages mating slots in the telescoping push arm members to lock their length during the initial stage of deploy of the platform downwardly from the vertical stowed position.

This electrical-wire cover is provided with the following: a corrugated-tube affixing part (29) and engagement ridges (49) integrally formed on a cover body (27) that surrounds an electrical wire; a bundling band that tightly secures first through third corrugated tubes; and bundling-member confinement parts (53) provided on the corrugated-tube affixing part (29). Each bundling-member confinement part (53) has first through third positioning parts (55, 57, 59) that have different bundling-band bridging positions.

A phase change memory device comprises a photolithographically formed phase change memory cell having first and second electrodes and a phase change bridge positioned between and electrically coupling the opposed sides of the electrodes to one another. The phase change bridge has a length, a width and a thickness. The width, the thickness and the length are less than a minimum photolithographic feature size of the process used to form the phase change memory cell. The size of the photoresist masks used in forming the memory cell may be reduced so that the width and the length of the phase change bridge are each less than the minimum photolithographic feature size.
