The present disclosure relates to an arrangement, a loop-shaped support, a prosthetic heart valve and a method of repairing or replacing a native heart valve. With the method or the arrangement, leakage or regurgitation between a prosthetic heart valve and the surrounding valve tissue is prevented. In one embodiment, an arrangement for replacement or repair of a native heart valve is provided, which comprises a loop-shaped support (41) and a prosthetic heart valve (70) and wherein an outer segment (32) of the loop-shaped support (41) is positionable towards surrounding valve tissue of a native heart valve and wherein an outer surface (74) of the prosthetic heart valve (70) is positionable towards an inner segment (34) of the loop-shaped support (41) so as to prevent paravalvular leakage or regurgitation between the prosthetic heart valve (70) and the surrounding valve tissue of the native heart valve.

A retractable awning includes a roller reversibly driven and mounted within a housing for support on a support structure and both inner and outer sets of pivotally interconnected support arms for supporting an awning canopy when extended. The inner set of support arms support the canopy beneath an inner segment of the canopy adjacent the support surface and are designed to deploy before the outer set of support arms with the outer set of support arms supporting the canopy beneath an outer segment of the canopy further away from the support surface than the inner segment. Both the inner and outer sets of support arms can be partially or fully deployed to regulate the extent to which the awning is extendible away from the support surface. The outer support arms are mounted for pivotal movement within a plane forming a different angle with horizontal than the inner set of support arms so the inner segment of the canopy above the inner set of support arms when extended forms a different angle with horizontal than does the outer segment of the awning canopy overlying the outer set of support arms when extended.

A monitoring camera with a far infrared capability has a cylindrical body (10), a lens hood (20), a luminous body (30) with multiple far infrared light emitting diodes (LEDs) and a lens cover (40). The lens hood (20) is a hollow cylinder and is divided into an inner segment and an enlarged outer segment (23) communicating with the inner segment. The enlarged outer portion (23) provides an enlarged compartment to hold a larger luminous body (30), which can hold more far infrared LEDs so the monitoring camera can see object at greater visual distances. Additionally, the field of vision the monitoring camera is also greater.

A stereoscopic digital image projecting system has a light source system providing polarized illumination having a first polarization state and a beam splitting system with a rotating segmented disk in the illumination, alternately generating first and second light beams, the rotating segmented disk having outer segments alternately transmissive and non-transmissive and inner segments radially aligned with the outer segments and alternately reflective and transmissive. A polarization rotator in a path of either the first or second light beam rotates the first polarization state to a second state orthogonal to the first. A combining system combines the first and second light beams into a combined light beam. A spatial light modulator modulates the combined light beam in a manner consistent with stereoscopic image data to form first and second modulated images having substantially orthogonal polarization states. Projection optics project the modulated images onto a display surface.

A method of tightening and loosening threaded connectors in an object includes threadingly connecting a nut with a bolt introduced in the object with interposition of a washer between the nut and the object, turning the nut by a tool to tighten or loosen the bolt in the object with interposition of the washer, forming the washer with an outer body having a radially inner opening larger than a diameter of the bolt and radially outer surface adapted to absorb a reaction force of the tool, optionally also with a radially inner segment engageable with a thread of the bolt and connectable to the radially outer body with a limited axial frictional movement relative to the outer body, and optionally also with a spacer locatable between the radially inner segment and the nut, interposing only said radially outer body of the washer between the nut and the object for regular applications, optionally interposing the radially outer body and the radially inner segment together between the nut and object for applications when even and accurate bolt elongation is necessary, and optionally interposing the radially outer body, the radially inner segment, and the spacer between the nut and the object for applications when a precise bolt load is needed and a bolt elongation must be controlled.
