Abstract: An information processing device includes: a display unit that displays information; a first detector that detects one of contact and proximity of the position indicator with respect to the display unit; a second detector that detects an operation of the operation key by a user; and a controller that issues an event for the operation key the operation of which has been detected by the second detector. The controller does not issue the event for the operation key in cases where none of the contact and the proximity of the position indicator has been detected when the second detector detects the operation of the operation key, and subsequently, when one of the contact and the proximity of the position indicator is detected, the controller issues the event for the operation key.

Abstract: A display device is connectable to a plurality of electronic pens and has a screen on which information is displayed in accordance with inputs from a plurality of electronic pens and a touch input. The display device includes a touch detection sensor, a wireless communication section, a display controller, and a touch panel controller. The touch detection sensor detects a touch on the screen. The wireless communication section receives signals from the plurality of electronic pens connected. The display controller determines a distance between at least two electronic pens out of the plurality of electronic pens connected, from the signals received via the wireless communication section. The touch panel controller enables or disables a function of the touch detection sensor based on the above determination.

Abstract: A cable dock assembly can include a first sub-assembly including a power adapter configured to attach to a power source, a second sub-assembly including a first video display plug configured to attach to a first video display, a third sub-assembly including a universal serial bus plug configured to attach to a computing device placed on a surface, a first electrical cable attached at the first sub-assembly and the second sub-assembly, a second electrical cable attached at the second sub-assembly and the third sub-assembly, and one or more controller chips. The one or more controller chips can be fully contained within at least one of the first, second, or third sub-assemblies. Other related assemblies and methods are also provided.

Abstract: Calcium silicate insulation consisting mainly of long, mutually entangled, fibrous synthetic xonotlite crystals and having a bulk specific gravity of 0.10 to 0.20 g/cm.sup.3 is produced at a very low cost without using any asbestos fibers by stirring very fine scattered ashes consisting mostly of amorphous silica, generated from furnaces where metallic silicon, silicon carbide, ferrosilicon, etc. are produced, with lime raw materials and water with heating, thereby obtaining a gel; kneading the gel under pressure, thereby obtaining a viscoelastic material just before transition to xonotlite crystals; pouring the viscoelastic material in a mold; and treating the viscoelastic material placed in the mold under saturated steam, thereby forming crystals, and successively treating the viscoelastic material under superheated steam, thereby effecting growth and drying of the crystals.
