Abstract: A “Contact Discriminator” provides various techniques for differentiating between valid and invalid contacts received from any input methodology by one or more touch-sensitive surfaces of a touch-sensitive computing device. Examples of contacts include single, sequential, concurrent, or simultaneous user finger touches (including gesture type touches), pen or stylus touches or inputs, hover-type inputs, or any combination thereof. The Contact Discriminator then acts on valid contacts (i.e., contacts intended as inputs) while rejecting or ignoring invalid contacts or inputs. Advantageously, the Contact Discriminator is further capable of disabling or ignoring regions of input surfaces, such tablet touch screens, that are expected to receive unintentional contacts, or intentional contacts not intended as inputs, for device or application control purposes.

Abstract: The present disclosure relates to a mobile phone and a method for answering such a phone automatically without user input. In one embodiment, the mobile phone detects that a call is being received. A proximity sensor is then used to detect the presence of a nearby object. For example, this allows a determination to be made whether the mobile phone is within a pocket of the user while the phone is ringing. Then a determination is made whether the proximity sensor changes states. For example, if a user removes the phone from their pocket, the proximity sensor switches from detecting something proximal to detecting that the phone is no longer in the user's pocket. Next, a determination is made whether the proximity sensor is again next to an object, such as an ear. If so, the mobile phone can be automatically answered without further user input.

Abstract: Described is a multiple display computing device, including technology for automatically selecting among various operating modes so as to display content on the displays based upon their relative positions. For example concave modes correspond to inwardly facing viewing surfaces of both displays, such as for viewing private content from a single viewpoint. Convex modes have outwardly facing outwardly surfaces, such that private content is shown on one display and public content on another. Neutral modes are those in which the viewing surfaces of the displays are generally on a common plane, for single user or multiple user/collaborative viewing depending on each display's output orientation. The displays may be movably coupled to one another, or may be implemented as two detachable computer systems coupled by a network connection.

Abstract: A touch sensitive computing system, including a touch sensitive display and interface software operatively coupled with the touch sensitive display. The interface software is configured to detect a touch input applied to the touch sensitive display and, in response to such detection, display touch operable user interface at a location on the touch sensitive display that is dependent upon where the touch input is applied to the touch sensitive display.

Abstract: A method and system for performing distance-based accelerated scrolling are described. The system accelerates scrolling based on the distance that a user has already scrolled, and continues to scroll in a quick manner. Using a conventional wheelmouse, consecutive quick flicks of the wheel may be used as an approximation of the distance that the user has scrolled, based on the effort the user expends flicking the wheel. The system inhibits acceleration when the user slows down or reverses direction in order to return fine scrolling capabilities to the user to locate an exact position in a data file.

Abstract: The present invention provides a systems, methods, and products for enhanced user navigation to compliment (but not necessarily replace) a computer keyboard and mouse by providing a robust navigation interface. The present invention may comprise: a minimally necessary group of commands; combining the functionality a set of at least two command calls into a single logical button; for a single button, prioritizing a set of command calls from first to last and then calling each until one is accepted; logically remapping commands to buttons for a navigational device coupled to a physically rotate-able display device; and mapping a substitute command to a logical button for when the button is engaged in a predetermined manner other than the primary manner in which the logical button is engaged (e.g., double-clicking, flicking, press-and-hold, etc.) so that a substitute command can in fact be issued, among others.

Abstract: A technique, specifically apparatus and accompanying methods, for implementing an on-demand “Tool Glass” based desktop user interface. The interface uses at least one input device capable of detecting touch. A sensed touch transition reflective of a user then making or breaking contact with the device, such by touching the device with a finger of a non-preferred hand or lifting his(her) finger from the device, causes a Tool Glass sheet to be displayed or dismissed. To prevent user distraction, these detected transitions preferably initiate corresponding predefined animation sequences that occur over preset time intervals in which the Tool Glass sheet either begins to fade into view as soon as user contact begins and then begins to fade out from view as soon as user contact ends. Such touch sensing can readily be used to provide “on-demand” display and dismissal of substantially any display widget, e.g.

Abstract: A circuit for regulating the output of a DC power supply that substantially eliminates turn-on transients induced by the switching of a silicon-controlled rectifier (SCR). A zero-crossover detector senses the AC voltage waveform of an applied power source and provides a trigger signal at the zero-crossing point. The trigger signal is applied to cause induction of the SCR's and raise the output voltage when the power supply output drops below a regulated value, and is interrupted so as to inhibit conduction of the SCR's and decrease the output voltage when the power supply output exceeds the regulated value.

Abstract: A remote indicator for displaying the position of a power control switch whether or not power is applied to the switch. An auxiliary DC power supply provides a reference potential to a plurality of voltage dividers. One voltage divider provides a first reference potential to a comparator. A second voltage divider and the reference power supply are connected through the power control switch so that a second reference potential is applied to the comparator when the power switch is closed. Differences of the two reference potentials corresponding to the open and closed switch positions are sensed by the comparator and used to activate an indicator accordingly.

Abstract: A DC voltage power supply circuit for suppressing turn-on transients applied to a switching voltage regulator circuit includes a relatively high impedance current suppression element connected in series between a rectifier circuit and a capacitive load, means for sensing a voltage drop developed across the suppression element, a diode network for developing a reference potential, and a silicon-controlled rectifier having a gate electrode responsive to the voltage drop developed across the current suppression element and the reference potential developed across the diode, for energizing a relay having contacts for disabling the switching regulator from supplying the load during the initial turn-on phase, and for shunting the current suppression element and activating the switching regulator after the capacitive load is substantially charged.
