Actuation of the primary manual release cable simultaneously unlocks the charge plug from the charge port and actuates the secondary tension cable system to unlock the charge port door lock.

Abstract: A harness for supporting a person working at height, including a back, leg loops, two forward connection arrangements and a flexible load-bearing member extending between the connection arrangements, which flexible load-bearing member carries a sliding attachment device attached to a climbing line. The forward connection arrangements transfers load from the back and the leg loops to the load-bearing member. Each forward connection arrangement includes: a body with apertures through which a leg riser webbing of the harness pass to connect the body to the back and the leg loops of the harness; and a bridge passage through which the flexible load-bearing member passes. A forward connection arrangement further includes a rope adjuster with a cam in the bridge passage. The cam pivots on an axle on the body. The cam cooperates with a locking surface of the body within the bridge passage to effect locking of a rope.

Abstract: Embodiments include a power source outputting power to drive speakers and lights in a venue; a control unit coupled to the power source and outputting multi-channel digital audio data to the speakers and light control data to the lights; and a unitary transmission bus coupling the output of the power source to the speakers and the lights and transmitting the power, the digital audio data, and the light control data to the speakers and the lights. The lighting control data comprises metadata superimposed over the digital audio data and power. Other actuators besides lights may also be used such as e.g. steam/water generators, smell/aroma generators, prop movements, LCD displays, hologram generators, and the like.

Abstract: An apparatus for supporting a person working at height includes a harness and seat assembly. The seat assembly includes a supporting platform, flexible connection members secured to the platform, and a connector on each flexible connection member. The harness has two forward connection arrangements and a flexible load-bearing member extending between the forward connection arrangements, the forward connection arrangements transferring load from the back and the leg loops to the load-bearing member. Each forward connection arrangement includes a body permanently connected to the harness and a retainer to secure the flexible load-bearing member to the body, and an attachment aperture through which a respective connector is passed to releasably connect the connector and the attached connection member to the forward connection member.

Abstract: Embodiments include a power source out-putting power to drive speakers and lights in a venue; a control unit coupled to the power source and outputting multi-channel digital audio data to the speakers and light control data to the lights; and a unitary transmission bus coupling the output of the power source to the speakers and the lights and transmitting the power, the digital audio data, and the light control data to the speakers and the lights. The lighting control data comprises metadata super-imposed over the digital audio data and power. Other actuators besides lights may also be used such as e.g. steam/water generators, smell/aroma generators, prop movements, LCD displays, hologram generators, and the like.

Abstract: Devices formed from interconnected components. Each assembled device comprises a yoke component, a boss component and an axle bolt. The yoke component comprising: a. carabiner body that includes a back, an opening, and a yoke formation. The yoke formation is constituted by a U-shaped section that is open to the outside of the body, and which defines a space between two legs, the legs having bearing surfaces through each of which a respective axle bore is formed. The back extends from the yoke formation to an end at a first limit of the opening. A spur extends from the yoke formation to an end at a second limit of the opening. A gate on the body can pivot between a closed position, in which it closes the opening, and an open position in which an object can be passed through the opening into a space within the body. The boss component has flat, parallel external bearing surfaces, an axle bore extending through the boss component, the axle bore opening at each bearing surface.

Abstract: A swivel comprises a first body component and a second body component with an interconnection assembly for interconnecting the first and second body components and to allow mutual rotation of the first and second components about a swivel axis. The swivel further includes a rotation limiting arrangement which, in a release condition, allows free mutual rotation of the first and second body components and in a first or a second locking condition restricts mutual rotation of the first and second body components. A user control is operable to selectively cause the rotation limiting arrangement to adopt one of a locking condition and the release condition. In the first locking condition, the rotation limiting arrangement prevents mutual rotation of the first and the second body components and in the second locking condition, the rotation limiting arrangement, allows limited mutual rotation of the first and second body components by less than 360°.

Abstract: Disclosed is a pulley assembly in a roped access system including first and second plates and a sheave carried for rotation about an axis normal to the plates. An aperture passes through each plate parallel to the axis. The plates have a closed condition when the apertures are coaxial with one another and the plates are in contact near the apertures, forming a rope passage extending between the plates adjacent the sheave, having an upper part smaller than parts of the passage below that upper part. A roped access system includes a climbing rope passing through the rope passage and a tether connected to the climbing rope above the pulley assembly by a friction hitch and an aperture of the pulley assembly, the hitch. The hitch grips the rope upon downward force to the tether, releasing its grip upon upward force to the friction hitch by pulley assembly plates.
