Abstract: A computer mouse including a base with bottom surface equipped with cushion members with slid-able sheets configured for sliding across the working surfaces and a tip with a base, which can be placed on the bottom surface or penetrate the bottom surface, where the base is not extended beyond the cushion members to avoid touching the working surfaces, and the tip is extended beyond the cushion members to provide a resistance point during mouse movement over the working surface, wherein the resistance point provides precise movement of the mouse over the work surface without affecting the position and navigation of the pointer on a computer screen.

Abstract: A computer mouse including a base with bottom surface for sliding across a work surface, with a retrievable tip for providing a resistance point for precision movements. At retrieved position, the tip is not touching the work surface, providing regular mouse movement. At working position, the tip is touching the work surface and creating resistance for precise movement of the mouse over the work surface. In some embodiments, computer mouse operated with tip in braked position allows the user to make rotational movements/gestures that can be registered by computer program to invoke actions. This new type of gesture is especially important for people with disabilities that have difficulties with existing gesture like clicking button. In some embodiments, computer mouse operated with tip in braked position allows users with hand tremor to improve cursor positioning by stopping cursor in vicinity of target, then reaching target by rotational movement.

Abstract: The invention relates to a process for preparing bromine-containing polymer, comprising a Friedel-Crafts alkylation reaction of tetrabromoxylylene dihalide, or tetrabromoxylylene dihalide in combination with pentabromobenzyl halide, with a reactant having one or more six-membered aromatic rings, wherein the reaction takes place in a solvent in the presence of a Friedel-Crafts catalyst, and isolating from the reaction mixture the bromine-containing polymer. The so-formed polymers and their use as flame retardants form additional aspects of the invention.
