Abstract: A transformable accessory for a handheld digital device, functions both as a protective cover and as a selfie stick, the accessory having a mounting chassis adapted for securing to a digital device, and an accessory member connected to the mounting chassis. transformable between first and second operative positions, and having a plurality of interconnected elongate, prismatic elements. In the first operative position the prismatic elements are in a side by side, coplanar formation extending across the rear of the mounting chassis cooperating therewith as a protective cover for the digital device. In the second operative position, the prismatic elements may be extended so as to form a rod which cooperates with the mounting chassis such that the combination of the rod and the mounting chassis become a selfie stick.

Abstract: Described herein is an integral range extender and mechanical protector system for a handheld digital device, which includes a chassis adapted for securing to the device; and a selectably-deployable dual purpose collapsible rod operable in a first, folded mode for storage across the rear of the device so as to cover a major portion of the area thereof thereby, together with said chassis, to absorb mechanical forces directed towards the sides or rear of the device. The system is further operable in a second mode for extension in a direction transverse from the chassis, whereby a first end is adapted to support the device and a second distal end is adapted to be held in the hand of a user, wherein, in said second mode, use of said collapsible rod permits positioning of the device from the user and use thereof remotely from the user.

Abstract: Optical and mechanical apparatus and methods for improved virtual interface projection and detection, by combining this function with still or video imaging functions. The apparatus comprises optics for imaging multiple imaged fields onto a single electronic imaging sensor. One of these imaged fields can be an infra red data entry sensing functionality, and the other can be any one or more of still picture imaging, video imaging or close-up photography. The apparatus is sufficiently compact to be installable within a cellular telephone or personal digital assistant. Opto-mechanical arrangements are provided for capturing these different fields of view from different directions. Methods and apparatus are provided for efficient projection of image templates using diffractive optical elements. Methods and apparatus are provided for using diffractive optical elements to provide efficient scanning methods, in one or two dimensions.

Abstract: The invention provides a process for removing discharged active zinc-containing material from a mechanically rechargeable zinc battery anode, containing the same, the anode being of the type comprising a skeletal frame, including conductive metal and having a portion of a surface area thereof formed as open spaces, and an active zinc anode component compacted into a rigid static bed of active anode material encompassing the skeletal frame, and having two opposite major surfaces, the process comprising introducing the anode between a pair of spaced-apart first and second crusher plates, each of the crusher plates being provided with a plurality of pointed projections of varying heights and a plurality of recesses of varying depths, the crusher plates being aligned with each other to the effect that tips of projections of the first crusher plate substantially mutually occlude with recesses provided on the second crusher plate and tips of projections of the second crusher plate substantially mutually occlude wit

Abstract: The invention provides a scraper for removing deposits from a major surface of an electrode in an electrochemical bath. The scraper consists of a plate which moves across the electrode surface. The scraper is provided with a scraper blade-retaining slot along one of its edges, the slot being angled relative to the plane of the scraper with its opening extending towards the electrode surface. The scraper also has a scraper blade which is removable from inter-engagement with the slot. In use, the scraper removes deposits from a major surface of an electrode in an electro-chemical liquid-containing bath.
