The functionality of "protected shareware" is controlled by digitally signed messaging protocol. Protective code within the shareware controls the functionality of the shareware in response to authorization messages which are supplied directly or indirectly by the shareware supplier. These messages are digitally signed in whole or part by or on behalf of the shareware supplier using the supplier's secret signing key. The shareware, in turn, includes the public checking key for this digital signa...

A container is manufactured by means of folding and sealing, and is intended to be used in extremely humid conditions, such as in an autoclave or in a cooling tunnel. The container has at least one liquid absorbing layer and all the cut edges of the container are protected.

A protective device for enclosing the scarf of a cannula carried by a boss while permitting access to the said scarf by a port of a Y-site which is located into proximity to an adjoining length of flexible tubing forming part of an intravenous administration set. The protective device has a cylindrical sheath portion surrounding the cannula, the ends of the cylindrical portion having at least one cutout which snugly receives the flexible tubing.

The disclosed capacitors include an assembly of a wound capacitor section having at least one metallized electrode, being prone to develop explosive pressure when a fault occurs, and an interrupter in series with the capacitor section. The interrupter cooperates mechanically with the wound section to rupture the interrupter in response to fault-induced internal pressure, the whole being contained in an enclosure.

A switch for transferring UBR traffic on an ATM network. The switch includes a mechanism for receiving UBR traffic from the network and sending UBR traffic to the network. The switch includes a mechanism for prohibiting a predefined condition in the UBR traffic, the prohibiting mechanism connected to the receiving and sending mechanism. Alternatively, the switch includes a mechanism for receiving UBR traffic in connections from the network and sending UBR traffic in the connections to the networ...

The invention provides a barrier means for a wooden flooring, especially useful for truck trailers and shipping containers. The flooring for such structures is comprised of a plurality of substantially parallel, wooden strips having their longitudinal edges in abutting relationship. A barrier film or fabric, which is permeable to vapor and impermeable to liquid, is disposed on the undersurface of the flooring, and discontinuous means adjoins or bonds the film or fabric to the flooring at least a...

A card assembly comprising a backing sheet, a first transparent film bonded to the backing sheet along one side margin area portion through a first pressure sensitive adhesive coating, a transparent releasable film attached to the first transparent film along the remaining area portion, a cut line of a generally closed-loop configuration formed through the first transparent film and the releasable film to define a configuration corresponding to the circumference of a thin article to be interpose...

In a first embodiment, a first fabric layer has gelatinous strips, thereby separating the first fabric layer into sections. A second fabric layer is positioned upon the first fabric layer, and an underwire is positioned on the second fabric layer opposite the first fabric layer. The first fabric layer is then folded onto itself to enclose the second fabric layer and the underwire. In a second embodiment, a third, or intermediate, fabric layer is positioned between the first and second fabric lay...

A protected configuration space is implemented as at least one range of memory addresses that are mapped to logic external to system memory. The memory addresses access logic that performs control and status operations pertaining to a protected operating environment. Some of the addresses may access protected configuration registers. Commands having destination addresses within the protected configuration space may not be completed if the commands are not issued by a processor, or if the command...

A protected switch has a power first semiconductor device having a first main electrode for coupling to a first voltage supply line, a second main electrode coupled to a first terminal for connection via a load to a second voltage supply line and an insulated gate electrode coupled to a control terminal for supplying a gate control signal to enable conduction of the power semiconductor device. A control arrangement has a normally off second semiconductor device having first and second main elect...
