A display for measured quantities can include a gauge with a set of indicia spaced around the gauge to indicate the measured quantities. A window can be formed in the gauge that extends along the set of indicia. An elliptical reflector can be positioned such that a first focus of the elliptical reflector is on the same axis as the center of the gauge with this axis perpendicular to the axis connecting the foci. An optical device can be mounted on a shaft and be arranged to redirect a light beam from a second foci of the elliptical reflector onto the elliptical reflector to generate a virtual pointer in the window. Means can be provided for turning the shaft to rotate the optical device. A light source can project the light beam onto the optical device. Rotation of the optical device can enable the virtual pointer to be selectively aimed at the set of indicia.

A user interface display system can include at least one user responsive element. The user responsive element can include an optical mechanism. A pulsed light source can produce a light beam. Apparatus are provided for causing the light beam to repeatedly scan across the activity field. A controller can be arranged to repeatedly turn the light source on at one or more predetermined scan positions to illuminate the user responsive element. The controller can also be programed to act upon a signal regarding the status of the element. A photo detector can send the signal to the controller. The optical mechanism acts upon the light beam differently based upon the status of the user responsive element.

A system and method for detecting the presence of a voltage on a ground conductor which is coupled to a protective Earth (PE) terminal associated with a power source. The power source is used to apply a voltage to a device. The system may use a high impedance device coupled across a switch, with the switch being in communication with a portion of the device. A control system may monitor a voltage across the high impedance device and determine if the voltage across the high impedance device exceeds a predetermined threshold. Exceeding the predetermined threshold indicates that an unsafe voltage from the power source is present on the ground conductor. A natural high impedance path between the device and the Earth is used to provide an Earth connection through the device to the Earth during operation of the system.
