An LCD precharge regulator circuit providing current directly from the input battery voltage to precharge the LCD display. A first switch activates a precharge regulator coupled to the unregulated DC input voltage, to supply the power for the initial current surge from the DC input to charge the LCD display. The precharge regulator includes a transistor and a biasing circuit. The biasing circuit initially turns the transistor fully on, but increasingly biases the transistor off as the LCD display charges to just below the operating voltage of the LCD display. A delay circuit activates a second switch after the LCD display is substantially charged, where the second switch connects the supply voltage from the DC/DC converter to the LCD display. At that point, the transistor is biased off, isolating the LCD display from the DC input voltage. Thus, the supply voltage need only sustain the charge on the LCD display after being substantially charged.

An improved camera system intended for a machine vision system which produces an image output that is specially adapted to be received by a machine vision system. In one embodiment, the camera system receives components from three portions of the electromagnetic spectrum, these being infrared, visible, and ultraviolet, and then combines these three portions essentially as expanded colors in an expanded version of an RGB "red/green/blue" video system. This provides a better image in all types of weather and visibility conditions. In addition, the camera system includes dynamic range transform logic which selectively compresses the dynamic range of the respective pixel values comprising the image to extract the most useful information from the extended dynamic range of the image. This reduces the amount of information required to be processed while retaining a quality image. The camera system also includes motion compensation logic that removes the motion or jitter caused by the camera system being subject to vibration from various environmental influences.

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.

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.
