Show moreA bolt having a shank and integral head has a strip of photoelastic material mounted in the head for manifesting in the form of photoelastic fringes linearly related to bolt tension the bending stresses created in the head during loading of the bolt. To determine the tension in the bolt during or after loading, polarized light is directed toward the photoelastic strip and reflected light from the strip is analyzed to measure fringe order. The fringe order is related to the amount of bending stresses in the head of the bolt by a predetermined calibration curve, the bending stresses being linearly related to bolt tension.

Show moreIonic contact is established and maintained between electrodes and soil in ohmic heating of a subsurface formation for recovery of volatile and semi-volatile materials, such as hazardous waste, hydrocarbon-like materials, and valuable minerals having thermally responsive properties. A compressed, dry sponge is wrapped around an electrode, which is then inserted into a bore hole. A conductive liquid is added to the bore hole, causing the sponge to swell, creating a stable and substantial interface for the flow of heating currents.

Show moreA method of securing against an unauthorized transmission within an authorized multimedia transmission from a sending data processor to a receiving data processor. The method includes altering the network transmission to interfere with the unauthorized transmission and render the unauthorized transmission invalid to the receiving data processor while not noticeably interfering with the streaming multimedia transmission. Monitoring for retransmissions or retransmission requests also serves as an indicator to an administrator that an unauthorized transmission is occurring. The method of this invention can be implemented by network administrator middleboxes such as firewalls. Sponsorship: Illinois Institute of Technology United States Patent Show less

Show moreAn electrohydrodynamic conduction liquid pumping system includes a vessel configured to contain a liquid or a liquid/vapor therein. This vessel can be of a elongate conduit configuration, an elongate channel configuration or a liquid enclosure configuration. At least a single pair of electrodes are disposed in a spaced apart relation to each other on the vessel and configured to be oriented in the liquid. A power supply is coupled to the electrodes and operable to generate electric fields in between the pair of electrodes, the electric forces inducing a net liquid movement relative to the vessel. Various electrode designs are embraced within the concept of this invention. Sponsorship: Illinois Institute of Technology United States Patent Show less
