The shells rotate about respective axes. In one configuration, the outermost shell is referred to as the “azimuth” shell because in use it rotates about a vertical axis. The next inner shell is an elevation shell that rotates about a first horizontal axis that is orthogonal to the axis of the camera or other sensor payload. An optional third shell can be used to provide “roll” motion, such as rotating a camera about its axis to obtain a particular rotational orientation with respect to a target. | 01-28-2010 |

The threshold voltage circuit provides an adjustable first threshold voltage at a first output and an adjustable second threshold voltage at a second output. The comparison circuit determines when the input voltage is greater than the first voltage threshold, including when the first voltage threshold is adjusted substantially up to a high supply voltage rail, and determines when the input voltage is less than the second voltage threshold, including when the second voltage threshold is adjusted substantially down to a low supply voltage rail. The output provides a first indication when the input voltage is greater than the first voltage threshold and to provide a second indication when the input voltage is less than the second voltage threshold. | 12-06-2012 |
