The W. & L. E. Gurley Building was constructed in 1862 in the Classical Revival style. The firm which originally commissioned the constructing, Gurley Precision Instruments, nevertheless occupies the ground floor although the upper floors include labs for RPI’s Lighting Investigation Center.

The Lightweight Laser Designator Rangefinder (LLDR) is a crew-served, Soldier-portable, long-variety, modular target locator and laser designation technique. The primary elements are the Target Locator Module (TLM) and the Laser Designator Module (LDM). The AN/PED-1A (LLDR-2) reduced program weight by far more than five pounds and lowered power consumption. the AN/PED-1B (LLDR 2H) improves target place efficiency.
The TLM incorporates a thermal imager, day camera, laser designator spot imaging, electronic show, eye-protected laser rangefinder, digital magnetic compass, Selective Availability/Anti-Spoofing Module Global Positioning Program (SAASM GPS) and digital export capability. the original LLDR 1 (AN/PED-1) operates on one BA-5699 battery, but it can also use a Single Channel Ground and Airborne Radio Technique (SINCGARDS) battery when laser designator is becoming fielded with the LLDR two (AN/PED-1A). It calls for much less energy and operates on 1 typical SINCGARS battery (BA-5390 or BA-5590). To supply a precision targeting capability to the dismounted Soldier, PM SPTD created the LLDR 2H (AN/PED-1B). It integrates a celestial navigation program with the digital magnetic compass in the TLM. The LLDR 2H provides very precise target coordinates to enable the Soldier to call for fire with precision GPS guided munitions. A Modification of in Service Gear program will retrofit fielded LLDR 1 and 2 systems with the LLDR 2H precision targeting capability beginning in FY13.
The TLM operates as a stand-alone device or in conjunction with the LDM. At evening and in obscured battlefiend circumstances, the operator can recognizee vehicle-sized taragets at much more than three kilometers. For the duration of day operations, targets Soldiers can recognize targets at far more than seven kilometers. The LDM emits coded laser pulses compatible with DoD and NATO laser-guided munitions. Soldiers can designate stationary targets at ranges higher than 5 kilometers.
