摘要： A portable computing device includes at least three buttons and circuitry for sensing the pressing of at least three buttons, one being recessed, and in response to such sensing provides a battery disable signal to a non-removable battery. The portable computing device further includes circuitry for sensing the coupling of the device to a device cradle, and in response to such coupling, or in response to the press of the recess button, provides a battery enable signal to the non-removable battery.

摘要： A simplified power on/off protect circuit is provided to enable logic above a predetermined power supply voltage level and disable the logic below such predetermined voltage level. The circuit comprises a zener diode in combination with a transistor such that the zener controls the voltage level at which the transistor turns on. The transistor enables the logic.

摘要： A system includes a capacitively-coupled touch sensor having a conductive first layer and a conductive second layer on a first insulative layer. The width of the second layer varies along an axis of the first layer. A first excitation signal is applied to one of the first and second layers and is capacitively coupled through a touch element to the other layer, producing a first signal that produces a second signal which is digitized. Digitized peak values of the second signal are processed to compute a value for a touch element location. A conductive third layer can be placed on the opposite side of the first layer has width varying oppositely to the second layer. The first excitation signal is applied to the second layer and a non-overlapping second excitation signal is applied to the third layer. The resulting digitized peak values are processed to cancel errors due to variations.
