International Classification:

B30B 1/38
H05B 3/26
G05D 15/01
G05D 23/27

US Classification:

219243, 219490, 219494, 1565831, 533707, 533737, 533759, 533766, 100319, 100 38

Abstract:

A heat sealer having a heated platen, a cylinder for reciprocating the platen, a die positioned to be engaged by the platen and a shuttle supporting the die to move the die from a platen-engaging position to a non-engaging position, and a control for controlling the temperature of the platen and the force applied to the platen against the die by the cylinder. The invention also includes a temperature sensor for sensing the surface temperature of the platen and a load sensor for sensing the force applied by the platen to the die. In one embodiment, the temperature sensor is an infrared temperature sensor that reads the surface temperature of the platen and the load sensor is a load cell positioned beneath the die and supporting the die so that the load sensors can measure the direct force applied by the platen against the die. Also, in one embodiment, the infrared sensor is positioned beneath the die so that it can read the platen temperature when the die is displaced to the non-engaging position.

Appl. No.:

8/220913

Iowa State University Research Foundation - Ames IA

International Classification:

G01T 1185

US Classification:

2503851

Abstract:

An integrated x-ray detection system includes an x-ray detector fabricated on a wafer with a housing for containing a gas. The detector has a plurality of microstrip anodes and the housing passes x-rays which partially ionize the gas thereby producing a pulse at one of the anodes. The same wafer also has a plurality of integrated active signal processing circuits which are respectively coupled to the anodes. Each active signal processing circuit receives and processes pulses from respective ones of the anodes and outputs a digital signal indicating the location and energy of x-rays detected by the detector. An isolation layer separates the x-ray detector from the active signal processing circuits.
