    摘要: A keyboard type input device has multiple key positions provided as character entry keys. Each key corresponds to one key in the selected row of the conventional QWERTY keyboard. A second set of control buttons provide for the selection of which row of a conventional QWERTY keyboard are represented by the character keys in addition to other functions such as case shift, and alpha-numerical control functions. A selected row is shown on a display, as visual feedback. Alternatively the keys are implemented as LCDs with pressure sensors and the characters of the selected row are displayed directly on the corresponding key positions. The keyboard finds particular use in portable devices as it demands less space than traditional keyboards. The keyboard type input device is implemented with various electronic appliances, including portable phones.

    摘要: A virtual input device uses the acoustical signature of the user's fingers to determine which character is selected. Rows of acoustical sensors having different acoustical properties are spaced in the vertical direction. When a user touches a specific row with a particular finger a unique acoustical signature is produced. The acoustical signature is analyzed to determine the finger used, the row, and the specific action by the finger, e.g. slide, press, tap. The combinations of the row, finger and action define the character selected. The characters are associated with the combinations in such a way to provide a traditional keyboard setup. Visual feedback of the character selected is provided by a display device of the system.

    摘要: A low-power dual-g.sub.m differential operational transconductance amplifier (OTA) having a differential input for improved common-mode noise rejection, a high transconductance for power savings, and circuitry for controlling its output conductance. The OTA includes a pair of input inverters for receiving differential input signals, a common-mode voltage control circuit for controlling the DC voltage levels of the inverters, and a Q-control circuit for adjusting the OTA's output conductance. The common-mode voltage control circuit has a pair of compensating current sources and a feedback loop acting as a high-gain amplifier. The high-gain amplifier has a pair of comparators for respectively comparing the DC voltage levels of the inverter outputs with a reference voltage. The Q-control circuit includes a current source coupled to a crossed-coupled NMOS transistor pair such that the OTA's output conductance may be controlled by adjusting the current source.
