摘要:
A system and method for enhancing the security of signal exchanges in a network system. The system and method include a process and means for generating one or more replacement encryption key sets based on information and events. The information that may cause the generation of a replacement encryption key set includes, but is not limited to, a specified period of time, the level and/or type of signal traffic, and the signal transmission protocol and the amount of data sent. A key manager function initiates the replacement encryption key process based on the information. The replacement encryption key set may be randomly or pseudo-randomly generated. Functions attached to the network system required to employ encryption key sets may have encryption key sets unique to them or shared with one or more other attached functions. The system and method may be employed in a wireless, wired, or mixed transmission medium environment.

A method and apparatus for delivering solvent free marking material to a receiver is provided. A printhead includes a discharge device having an inlet and an outlet with a portion of the discharge device defining a delivery path. An actuating mechanism is moveably positioned along the delivery path. A material selection device has an inlet and an outlet with the outlet of the material selection device being connected in fluid communication to the inlet of the discharge device. The inlet of the material selection device is adapted to be connected to a pressurized source of a thermodynamically stable mixture of a fluid and a marking material, wherein the fluid is in a gaseous state at a location beyond the outlet of the discharge device.

A terminal block for conductively coupling multiple pairs of electrical wires includes a deadfront cover mounted onto a non-conductive base so as to define multiple pairs of wire receiving receptacles, each pair of wire receiving receptacles being electrically connected together via a conductive bus bar. As one feature of the present invention, a conductive shunt can be disposed by means of a manually operable shunt switch to selectively contact all of the bus bars in order to discharge any current present thereon. As another feature of the present invention, a plurality of finger-safe captive screw assemblies are retained within the cover, each captive screw assembly including a screw which can be driven into a threaded bore formed in one end of a corresponding bus bar. As yet another feature of the present invention, multiple pairs of interchangeable end caps can be removably snap-fit mounted on the base to enable the terminal block to be retained onto a wide variety of different surfaces. As yet still another feature of the present invention, a DIN rail lock is retained between each end cap and the base and includes one or more sharpened teeth which can be driven into the surface of the DIN rail to lock the terminal block in place.

This invention relates to macrocyclic molecules which inhibit metalloproteinases, including aggrecanase, and the production of tumor necrosis factor (TNF). In particular, the compounds are inhibitors of metalloproteinases involved in tissue degradation and inhibitors of the release of tumor necrosis factor. The present invention also relates to pharmaceutical compositions comprising such compounds and to methods of using these compounds for the treatment of inflammatory diseases.

A method of shortening cycle time required to compression mold shingle or tile is provided, wherein carrier plates are comprised of a surface material and a base, and receive a thermoplastic material, thereon. The roofing material is applied to the carrier plate and the carrier plate is subjected to induction heating, by which its surface material has its temperature raised, without substantially raising the temperature of the carrier plate base, such that the thermoplastic material applied thereto is kept heated in the compression mold. Cooling of the thermoplastic material is by heat transfer from the carrier plate surface material to the carrier plate base, and with both materials having good heat conduction capability. The carrier plate surface material has a high receptivity to being heated by induction heating relative the carrier plate base. The carrier plates are serially delivered through the process, to the compression mold.
