Abstract: In refrigerator tractor/trailer vehicles, a data acquisition module is connected with one or more temperature sensors adapted for measurement of the temperatures within the trailer and may be connected with one or more distance sensors and "door open" sensors located in the trailer. Such a data acquisition module preferably comprises a microprocessor and random access memory connected with a plurality of sensors and adapted to acquire stored data on temperatures within the trailer and further connected with clock means to provide time data associated with the temperature data. In such systems, a control and display module, which comprises a separate portable control and display unit, can provide temperature data and distance data to the vehicle operator, warnings to the vehicle operator if the temperature of the trailer approaches unacceptable limits, warnings during backing of the trailer of impending collision with an object and warnings if the trailer doors are opened without authority.

Abstract: A method for formation of duct from preformed pieces. A number of ductwork pieces are formed out of sheet material, the pieces having edge configurations adapted to interlock with each other to form a seam of a completed duct. The individual pieces are fed into an edge interlocking machine and are acted upon by the machine to form a duct having a predetermined length. The machine includes a stationary frame member, guide rails elongated in the direction of ductwork movement through the machine, rollers associated with at least some of the guide rails for effecting interlocking of the edge configurations of the duct work pieces to form duct seams, and structure for mounting the guide rails to the frame member. The guide rails are relatively movable with respect to the frame member and to each other to form ducts of different sizes and so that transition ducts can be formed as well as straight duct.

Abstract: An electrical output signal from an electro-optical code reader is amplified (U1) to develop a first signal which is applied to a positive peak detector (U2D1, C2) and a negative peak detector (U3, D2, C3). The positive peak detector provides a second signal whose voltage level follows that of the first signal as the first signal increases, from the time that the voltage level of the second signal is brought substantially equal to that of the first signal to the time that the first signal begins to decrease, with the voltage level of the second signal thereafter being maintained substantially constant. The negative peak detector provides a third signal whose voltage level follows that of the first signal as the first signal decreases from the time that the voltage level of the third signal is brought substantially equal to that of the first signal to the time that the first signal begins to increase, with the third signal thereafter being maintained substantially constant.
