Hossein Zarrineghbal - Winchester MA
Robert F. Golden - Acton MA

Assignee:

Charm Sciences, Inc. - Malden MA

International Classification:

M61L 200

US Classification:

422 21

Abstract:

A high temperature, short time microwave heating system 10 for heat-sensitive liquid material to inactivate or reduce pathogenic agents or organisms, such as viral contaminants. The system 10 includes a disposable cartridge 26 consisting of a preheater 32, a microwave heating coil 56 and cooler 58 with the heating coil 56 adapted to be easily inserted in and removed from the microwave heating field.

International Classification:

US Classification:

433 68

Abstract:

A contact sensor for detecting points on a grid where the sensor is being contacted on opposing sides by teeth surfaces or other contacting points. The sensor is especially useful for measuring dental occlusion. The contact sensor includes two sets of parallel electrodes which are each formed on a thin, flexible supporting sheet. The electrodes are separated by a thin, pressure-sensitive resistive coating such as molydenum disulphide. Two such electrode structures are oriented at approximately right angles to create a grid where the intersecting electrodes cross separated by the resistive coatings. Several arrangements of resistive coating over electrodes as disclosed. In the absence of an external force, the material between the electrodes sets provides a high resistance between intersecting electrodes. The resistance between electrode intersections changes as pressure on opposite sides of the intersection changes. The sensor output is dynamic in that the resistance will vary as external pressure is repeatedly applied and removed.

Abstract:

A contact sensor for detecting points on a grid where the sensor is being contacted on opposing sides by teeth surfaces or other contacting points. The contact sensor includes two sets of parallel electrodes which are each formed of a thin, flexible supporting sheet. The electrodes are coated with a thin, resistive coating. Two such electrode structures are oriented at approximately right angles to create a grid where the intersecting electrodes cross separated by the resistive coatings. The resistive coatings may be made from conventional resisitive inks and are optionally separated by a separation material, such as talcum or mesh. In the absence of an external force, the material between the electrodes sets provides a high resistance between intersecting electrodes. The novel composition of the intermediate layer results in a structure which provides a "switching" effect such that the resistance between electrodes is very high where there is no external pressure and changes to a comparatively low value at locations where external pressure is applied by two contacting points or surfaces. The sensor output is dynamic in the sense that the resistance will change back and forth between high and low resistance states as external pressure is repeatedly applied and removed.
