Abstract: A repeater for maintaining wireless line of sight communications. The repeater is autonomously repositional in both absolute location and azimuthal orientation. The repeater has at least two vibratory motors, or other vibration sources, which provide oscillations to depending legs against a support surface. By selectively operating one or more of the vibration sources together or independently, the repeater may be moved as helpful to maintain line of sight communication with another repeater or other operational hardware. A command signal from a remote base station controls the locomotion of the repeater to provide both a change in absolute position relative to the surroundings and a rotational change in azimuthal orientation as necessary to maintain communication under dynamic conditions.

Abstract: An apparatus (100) for actuating a locking mechanism (12) of a locking sail track car (10) comprises a latch formation (116) disposed in a fixed position with respect to the track (14), a control surface (112) spaced from the latch formation (116) in a hoisting direction, and an actuator assembly (120) for attachment to the car (10). The actuator assembly (120) comprises an actuator (124) for operating a control member (24) of the car locking mechanism, and a latch element (158) connected to the actuator (124) and moveable between a first detent position in which the latch element (158) is not engageable with the latch formation (116) and a second detent position.

Abstract: A lock apparatus is provided for releasably securing a load, such as a sail, to a supporting structure, such as a mast while the load applies force in a load direction. The lock apparatus comprises a lock member attached or attachable to the load and a lock assembly for attachment to the supporting structure. The lock assembly comprises at least one locking element configured to move between a locked position in which the locking element blocks movement of the lock member in the load direction, and an unlocked position, an actuator, and a releasable coupling for coupling the actuator to the lock member. The coupling is arranged to couple the actuator to the lock member upon movement of the lock member towards the actuator in an insertion direction, opposite to the load direction.

Abstract: A method and system for retrieving information in response to an information retrieval request comprises extracting additional information from a first corpus of data elements based on the request. The request is modified based on the additional information to refine the scope of information to be retrieved from a second corpus of data elements. The information is retrieved from the second corpus of data elements based on the modified request.

Abstract: A modified umbrella, cane or similar device's handle consisting of a knob attached to the end of the handle. The handle is shaped in such a matter to facilitate the attachment of the knob and placement of the knob such that the knob would be in contact with a flat surface if the umbrella, cane or similar device were hung from that flat surface. This knob would increase the lateral fiction of the handle and keep it from sliding on the flat surface.

Abstract: A fluid compressor comprises a casing containing liquid and having located within it a shaft driven radial impeller for pressurizing the liquid before it is fed to a further rotatable structure. By rotation of the impeller and the further rotatable structure, the high pressure liquid compresses a gas or vapor within the compressor casing and expels it from the casing through an outlet port therein. The high pressure liquid inlet end of the rotatable structure is partially shrouded by a shroud structure to restrict the input of high pressure liquid to part of the rotatable structure. The shroud structure has an opening therein which allows the high pressure liquid entering the rotatable structure to be depressurized and returned to the inlet end of the radial impeller after compressing the gas or vapor. By so doing, further gas or vapor for compression will be drawn into the compressor casing.
