Abstract: A rail having a recess or groove therein, wherein a heater is located at least partially within the recess or groove, and a method of manufacturing same, including providing a forming a rail with a recess or groove therein, and installing a heater in the recess or groove.

Abstract: Provided is a method for the management of a patient's ophthalmic information which enables eyecare professionals, particularly ophthalmologists, to obtain, with a patient's consent, a patient's latest optical data, including that derived from prior ophthalmological surgical procedures. Subsequent surgical procedures, performed using such data and surgical parameters calculated therefrom, can give results having increased effectiveness.

Abstract: A system for generating radiant heat in a transit vehicle includes at least one floor panel having at least one heating element disposed therein, and a power switch operably disposed intermediate a power supply source and the heating element for selectively providing and discontinuing a supply of a predetermined power generated by such power supply source to and from such at least one heating element.

Abstract: An environmental control apparatus controls humidity and temperature in a closed environment such as may exist in outdoor electrical switchgear boxes and the like. Temperature and humidity sensors are coupled to a controller which compares the sensed conditions to low temperatures and a high humidity setpoint. If either the temperature is below the temperature setpoint or the humidity is above the humidity setpoint a heater is energized until the respective condition is corrected. A high temperature cutout is provided to prevent high humidity conditions from causing the heater to raise the temperature to excessive levels. Typically, the controller engages the heater at temperatures of below 40.degree. F., humidity levels of above 65.degree. b, with a high temperature cutout at 140.degree. F.
