Abstract: A composition for protecting a surface of an inorganic substrate, such as concrete, terrazzo, or ceramic tile, includes a silicate (e.g., an alkali metal polysilicate or a colloidal silica), a siliconate (e.g., a metal siliconate, such as an alkali metal methyl siliconate, etc.), acrylic latex, a silane coupling agent, and a solvent, such as ethylene glycol monobutyl ether. Inorganic substrates, such as concrete, stone, and ceramic materials, with such a composition on their surfaces are also disclosed, as are methods for polishing and protecting inorganic substrates.

Abstract: A game controller comprising: a hand-held base unit comprising one or more base unit actuators, each configured to generate a respective actuation signal in response to user input; and a module comprising two or more module actuators, each configured to generate a respective actuation signal in response to user input. The module is mounted to the base unit and can be rotated horizontally between two or more orientations to adjust the configuration of the module actuators relative to the base unit actuator(s).

Abstract: Methods for signal processing employ instantaneous frequency analysis through quadrature genometric measurement of streaming signal data. Such methods may include the analysis of any composite analog periodic signal, including but not limited to audio, video, radio, seismic, light, radar, sonar, EKG, where signal data is streaming, stationary or non-stationary, and represents either linear or non-linear processes.

Abstract: A portable puppet theater, stage or playhouse comprises hanging wall structure for hanging the puppet theater or playhouse from a door or other vertical surface, enclosure structure for suspending from the hanging wall structure, the enclosure structure being shaped to form an enclosure, and shaping means associated with the enclosure structure for extending the enclosure structure away from a door or other vertical surface. The shaping structure within the enclosure structure may be disposed to be pivotable between a first position extending the enclosure structure away from the door or other vertical surface, and a second position maintaining the enclosure structure substantially flush against the door or other vertical surface.
