摘要： Apparatuses and methods of converting a capacitance measured on a sense element to a digital value are described. One apparatus includes a modulator having a modulator capacitor, a sense element selectively coupled in a feedback loop of the modulator to operate as a switching capacitor. The apparatus also includes a first switch coupled between a voltage source and a first node of the switching capacitor and a second switch coupled between the first node of the switching capacitor and a first node of the modulator capacitor. The switching capacitor provides a charge current to the modulator capacitor via the second switch. The modulator measures a capacitance of the sense element and converts the measured capacitance to a digital code representing the capacitance.

摘要： A method for measuring for generating a touch capacitance measurement is provided. Gain and offset control signals are generated, where the gain and offset control signals are adjusted to compensate for base capacitance of a touch sensor. The gain control signal is applied to a touch sensor during a first phase of a clock signal, and the offset control signal is applied to an output circuit during a second phase of the clock signal. The output circuit is coupled to the touch sensor during the second phase of the clock signal. The touch capacitance measurement is generated by compensating for the base capacitance with the gain and offset control signals, and a gain is applied to the touch capacitance measurement.

摘要： A method of detecting and recovering from stuck keys on an electronic device keyboard comprises receiving one or more messages by a processor based upon a predetermined periodic scan rate and each message corresponding to a pressed key, determining one of the pressed keys is a stuck key based upon the received one or more messages corresponding to a pressed key, sending a mock key-up message from the processor to a keyboard controller in response to the determined stuck key, operating the keyboard controller at a changed scan rate in response to the mock key-up message, detecting the electronic device keyboard is in a released key state by the processor; and operating the keyboard controller at the predetermined periodic scan rate in response to the detected released key state. The processor can include two components, such as a keyboard processor and a keyboard controller.

摘要： The present invention relates to a touch sensing device, touch screen device, mobile device and method for sensing a touch and, in particular, to a touch sensing device usable as user interface for controlling various functions in different devices to provide additional and more flexible input operations. The touch sensing device comprises a cover layer defining a touch area, a first winding placed on one side of said cover layer and extending over at least a part of said touch area, and a second winding placed on the same side of said first winding, being spaced apart from said first winding, wherein said first and second windings and said cover layer are arranged so that a coupling of a magnetic field generated by a current supplied to said first winding varies in response to a force onto the touch area.

摘要： This invention relates to a multi-tap and combinational alphanumeric data entry on a 12 key device. The [1] key on is labeled with the “.QZ”. Numbers are produced by activating ten numbered keys. Activating the [#] key backspaces. Activating the [*] key one or more times enters an alphabet mode. Activating [1]-[9] keys once produces left data, twice produces middle data and three times produces right data. Activating the [1] then [*] keys produces the “-” dash. Alternatively, simultaneously activating [1]-[9] keys and a left [*] key produces left data, simultaneously activating [1]-[9] keys and a middle [0] key produces middle data and simultaneously activating [1]-[9] keys and a right [#] key produces right data. Activating the [#] key enters a data character for the next data entry on the same previously activated key. Activating the [*] key, after entering a data character, produces the shift function. Activating the [*] key twice produces the backspace function. Activating the [0] key produces a space. Activating the [0] key twice produces a Tab or Enter function. Activating the [#] key twice re-enters the number mode. Activating the [#] and [*] keys enters a first punctuation/symbol mode, where activating [1]-[9] or [0] keys produces left data. Activating the [#] and [*] keys and the [*] again enters a second punctuation/symbol mode, where activating [1]-[9] or [0] keys produces middle data. Activating the [#] and [*] keys and the [*] two more times enters a third punctuation/symbol mode, where activating [1]-[9] or [0] keys produces right data. The alphabetic mode is automatically re-entered into after the punctuation mark or symbol is produced. An entered punctuation mark is followed by a space. Activating the [*] key after the punctuation mark and space is produced, deletes the space after the punctuation mark. Activating the [0] key after a period and space is produced, deletes the space after the period. Simultaneous two key entry increases data input speed by reducing the amount of entries required.

摘要： A computer receives data from a keyboard having one or more keys which cause generation of keyboard data that quantitatively describe the relative force applied to those keys. The keyboard data are transmitted in an HID report containing identifiers for one or more keys that have been pressed and force data for each key. The force data may be a multi-bit value quantifying the key force, or a null indicator signaling that the key is not force-sensing. Keyboard data messages are then prepared which identify keys pressed, contain force data, and may indicate whether the force data updates previous force data. Force updates are only provided to application programs registering for key force data. In other aspects of the invention, key repeat messages are automatically generated for a key held pressed by a user. The key repeat messages are generated at a rate controlled by the amount of force applied to the key.

摘要： An electronic calculator is provided which generates confirmation sounds identifying actual depression of any keys of a keyboard. The calculator includes a piezoelectric acoustic element which is responsive to key signals derived from a processor unit when any keys of the keyboard are manually operated. The calculator generates these sounds only for a fixed period of time starting with actual depression of any keys. The processor unit generates key-strobe signals which are input to the keys on the keyboard. Each key has its own key-strobe signal, and, when depressed, the signal is passed to the processor uniquely identifying each key. The processor generates sound instruction signals indicative of normal and erroneous operational states in the calculator in accordance with the received key-strobe signals. An audible confirmation or alarm sound is then generated in accordance with the sound instruction signal.
