摘要： A high impedance tap for monitoring traffic over a communication link of a fast Ethernet local area network (LAN). The circuit of the present invention is advantageously used for tapping into a fast Ethernet communication link (e.g., bi-directional communication channel) of a LAN using, for instance, {fraction (10/100)} BaseT Ethernet communication protocol. The novel circuit is particularly useful in point to point communication links (e.g., supporting fast Ethernet communication) where two communication nodes are coupled together using a bi-directional communication link (e.g., two twisted pair cables). Unlike the prior art monitoring probes, the probe of the present invention does not insert itself in series between the communication link, but rather taps onto the communication link in parallel using a high impedance termination circuit thereby leaving the existing communication link undisturbed electrically. By leaving the communication link undisturbed electrically, the probe of the present invention does not introduce latency into the communication link nor does it interrupt the communication link for any reason (e.g., during auto-negotiation sessions or on power down, power interruption, etc.). The high impedance value selected for the present invention is approximately one order of magnitude greater than the individual termination impedance of the communication nodes. The particular termination circuit used can employ a parallel coupled resistor with optional capacitors coupled to each wire of a twisted pair cable. The probe can be attached to a number of different statistics gathering systems (e.g., of the RMOD and RMOD2 standard) or various types of traffic accounting systems.

摘要： A sealer to bond film having a high temperature resistance (e.g., ceramic) substrate with properly sized groove receiving a heater element as in a flat faced wire band in a tight, flush to adjacent film presentation surface arrangement. A stacked ceramic plate set with wire band within a groove defined by an intermediate stack insert is a suitable substrate. The band is retained flush by a positioner securely locking down one end while the other end is provided at a housing body access location. The sealer is suited for use as a product-in-bag sealing device (products such as air, foam, foodstuff, etc.) with the heater element in contact with film to form a seal. A drag seal arrangement, where film layers are drawn past a fixed or adjustably mounted heater element is an example.

摘要： A material spill prevention system with feed location sensing system to reduce the possibility of material spillage relative to the film being utilized for bag formation. The material spill prevention system monitors whether there is a proper film feed situation and, if not, precludes the release of material from the dispenser as in by precluding a flow controller opening and the release of material to the bag intended to receive the release chemical (e.g., a foam packaging bag). The prevention system is applicable to a variety of film feed arrangements as in a C-fold film drawn by a nip roller arrangement from a roll source with the dispenser mechanism positioned intermediate the nip and film source relative to film travel. An embodiment of the spill prevention system also features an absolute position transducer for monitoring position of a flow controller which controls output of material from the dispenser.

摘要： A selection resource executed within the network is configured for selecting from among a plurality of servers, distributed throughout the network at respective network-based server locations in each configured for providing a specified service, a selected server for providing the specified service for a client device at a network-based client location. The selection resource selects the selected server based on the corresponding server location relative to the client location, and causes a request having been generated by the client device to be sent to the selected server. Hence, the selection resource optimizes client-server interactions in a distributed computing network, based on the client location and the server location.

摘要： A catheter handpiece apparatus and method for delivering a desired dose with minimal potential for contamination of the injected substance and rapid, accurate delivery of the desired dose. In one embodiment, a carriage assembly affixed to an inner lumen is slidably located within a handpiece housing equipped with an outer lumen. The carriage assembly receives a dose carpule. An actuator knob cocks the carriage assembly and a spring-powered actuator mechanism. After the catheter is maneuvered to a desired injection site and a desired dose is set, depressing a first trigger causes the inner lumen tip to extend beyond the outer lumen into the injection site. Depressing a second trigger causes the actuator mechanism to push the desired dose from the dose carpule through the inner lumen into the injection site. A second embodiment provides a catheter handpiece with a carriage assembly cocking lever and an operator-powered dose delivery mechanism.

摘要： A carrier vessel for a pneumatic tube transport system provides substantially leak-free containment of fluids transported therein. The vessel includes first and second shell members having opposing engagement surfaces extending substantially about a perimeter thereof. A sealing member disposed adjacent one of the engagement surfaces is compressed between the engagement surfaces when the vessel is closed to provide substantially fluid-tight seal between the first and second shell members. The vessel includes removable wear bands connected to the shell members, a hinge interconnector assembly for connecting the shell members together at one of their longitudinal sides and latch assemblies for releasably connecting them together at an opposite longitudinal side.
