Abstract: A heating cabinet for IV bags provides a uniform thermal field promoted by circulated heated air passing through air permeable shelves. Temperatures of the IV bags are modeled through a knowledge of a temperature of the uniform thermal field and arrival time of the IV bags eliminating a need for separate temperature sensors and control loops. Bag status may be signaled through modulated light distinguishable by individuals with limited color sensitivity. Signals are associated with particular IV bags by projecting the light of the signals into the IV bags themselves.

Abstract: A portable apparatus and a method for inserting digitized previously recorded or fabricated radio frequency (RF) pulse descriptor word (PDW) data files into an electronic surveillance (ES) system to realistically simulate a complex RF environment. The apparatus includes a personal computer and an electronics unit configured for easy integration into an ES system between the receiver and pulse processor. PDW data files are created on the personal computer and transmitted to the electronics unit as supplied PDW data. In the primary embodiment, real RF pulse data from the receiver is halted in the electronics unit and supplied PDW data and data from the receiver unrelated to PDW data, is passed in a continuous stream to the pulse processor. In a secondary embodiment, an upgrade in the electronics unit multiplexes both real RF pulse data and supplied PDW data for transmission to the pulse processor.
