| 20110304577 | CAPACITIVE TOUCH SCREEN STYLUS - In some embodiments, a stylus for providing input to a capacitive touch screen, having a tip including or consisting of conductive felt, which provides a deformable conductive surface for contacting the touch screen. The tip is produced by felting base fibers (which are typically non-conductive) with conductive fibers. In other embodiments, a capacitive touch stylus having at least a first mode of operation and a second mode of operation, and including at least one conductive tip and switched circuitry (preferably, passive circuitry) including at least one switch biased in a default state indicative of the first mode of operation but switchable into a second state indicative of the second mode of operation in response to movement of the tip (typically, in response to exertion of not less than a threshold force on the tip). In some embodiments, a stylus having a conductive tip (e.g., a conductive, felted tip) and including switched circuitry (preferably, passive circuitry) having a first state which couples a capacitance to the tip, where the capacitance is sufficient to allow a capacitive touch screen device to recognize (as a touch) simple contact of the tip on the screen of the touch screen device, and a second state which decouples the capacitance from the tip, thereby preventing the touch screen device from recognizing (as a touch) simple contact of the tip on the screen. | 12-15-2011 |
| 20090195406 | Controller Having Reduced Control Key Set and Method for Operating Same in a Learning, Macro, or Cloning Mode - In some embodiments, a wall-mountable, configurable controller having control keys (e.g., less than eight keys or another small number of keys), a subassembly including circuitry, and a control key insert removably mountable to the subassembly and including at least one of the control keys. The circuitry can include a limit switch that is biased in a default state but moveable into a learning state in response to user-exerted force. In some embodiments, the controller includes an IR emitter and an IR receiver and is operable to clone another device by sending configuring radiation from the emitter to the other device's IR receiver. Preferably, the emitter and receiver are positioned so that a controller's IR emitter aligns with the IR receiver of an identical controller when the controllers are positioned face to face. In some embodiments, the controller provides audible and visual feedback to users when operating in a learning mode. | 08-06-2009 |
