摘要:
A railroad track inspection system and method for facilitating inspection of a rail component while traveling on the railroad track. The railroad track inspection system includes an optical path protection device for a protective window for optical sensors of an optical inspection system when it becomes contaminated with dirt, dust, mud, grease, and other contaminants that block or obscure an optical path of the sensors. The optical path protection device eliminates the need for a human operator to perform the periodic cleaning of the protective window by using a clear film with an automated advancement mechanism for providing clean film, as needed, for keeping the optical path of the optical sensors unobstructed and clear.

A wall mount (for example, a window mount) dual fan includes two independently controlled fans controllable to move air in the same direction or in opposite directions. Each fan includes a temperature sensor to measure temperature of air moving through each fan. The fans are energized periodically for a short time period to make accurate temperature measurements. When the combined temperature measurements indicate an advantage from fan operation, the fans are activated.

An offset window mount fan unit includes two or more independently controlled fans controllable to move air in the same direction or in opposite directions. A housing substantially offsets the fans from a direct passage of air into the room. In one embodiment, the fans are mounted in a housing perpendicular to the window, air traveling through the fans turning 90 degrees to pass through the plane of the window and 90 degrees down into the room. Each fan includes a temperature sensor to measure temperature of air moving through each fan. The fans are energized periodically for a short time period to make accurate temperature measurements. When the combined temperature measurements indicate an advantage from fan operation, the fans are activated. An evaporative cooling section may be attached to an outside portion of the unit to provide additional cooling.

A wall fan includes a control circuit both controlling the wall fan and a temperature control unit comprising a heater, a cooler, or a Heating, Ventilating, and Air Conditioning (HVAC) system. The control system receives a desired temperature and compares the desired temperature to an outdoor temperature. When the outdoor temperature indicates that drawing outside air into indoor space will drive the indoor air temperature towards the desired temperature, the control system activates the wall fan, and de-energizes the heater, cooler, or HVAC system. When the outdoor temperature indicates that drawing outside air into indoor space will not drive the indoor air temperature towards the desired temperature, the control system de-energizes the wall fan, and energizes the heater, cooler, or HVAC system.
