SYSTEM AND METHOD FOR PROVIDING A DISPLAY UTILIZING A FAST PHOTON INDICATOR
First Claim
1. A measuring gauge comprising:
- a rotatable LED pointer having a light output, the output of the LED pointer appearing an arc of light to a user as the pointer is rotated, the arc of light representing a quantity of a desired display unit;
a rotary transformer;
a brushless motor magnetically coupled to the LED pointer;
a high speed controller coupled to the motor and the rotary transformer, the controller receiving an indication of the quantity and responsively programmed to actuate the rotary transformer in order to illuminate the LED pointer rotating radially about a face of a graduated lens at a substantially constant speed and to activate and deactivate the LED pointer so as to adjust the length of the arc of light and thereby to indicate the quantity of the desired display unit to the user;
a touch switch to allow the user to view, reset, and program operating functions of the gauge; and
circuitry for sensing the ambient light level for responsively controlling the intensity of the LED pointer and a LED shift light output.

Abstract
A measuring gauge includes a rotatable LED pointer having a light output. As the pointer is rotated about a lens at a constant rate, the output of the LED pointer appears as an arc of light to a user. The arc of light represents a quantity of a desired display unit. A brushless motor and a rotary transformer are magnetically coupled to the LED pointer. A high speed controller is coupled to the motor and the rotary transformer. The controller receives an indication of the quantity and is responsively programmed to actuate the rotary transformer in order to illuminate the LED pointer as it rotates radially about a face of a graduated lens at a substantially constant speed and to activate and deactivate the LED pointer so as to adjust the length of the arc of light and thereby to indicate the quantity of the desired display unit to the user.
