Access of devices to the wireless network may be blocked or limited based on monitored behavior.

Abstract: A system and method for mediating the routing of asynchronous messages includes routing the asynchronous message to a first recipient, determining whether the first recipient opened the asynchronous message, and re-routing the asynchronous message to a second recipient who is qualified to receive and respond to the message if the first recipient fails to open the message. In an aspect, the second recipient is selected based upon the role that the second recipient performs within the system. In another aspect, the message is re-routed to the second recipient if the first recipient fails to open the message within a deadline imposed by the message sender. In another aspect, the message is re-routed to the second recipient if the first recipient fails to open the message within a deadline automatically imposed by the system when the message is of a certain type.

Abstract: A catheter connection system is defined by a rigid, tubular stem attached at a proximal end thereof to a medical device. The stem has a plurality of comparably configured engagement barbs encircling and radially, outwardly extending on an exterior surface of the stem. A locking barb also encircles and radially, outwardly extends on the surface of the stem between the medical device and the engagement barbs. A rigid first locking sleeve is provided for inwardly compressing a portion of a body wall of a silicone catheter against the locking barb on the stem when the stem is received in the lumen of the silicone catheter to create a mechanical joinder and liquid-tight seal between the silicone catheter and the stem. In the alternative, a compression sleeve housed within a rigid second locking sleeve is provided for compressing a body wall of a polyurethane catheter against the engagement barbs on the stem to create a mechanical joinder and liquid-tight seal between the polyurethane catheter and the stem.

Abstract: A label construction formed of a first bottom panel with an adhesive backing for affixation to a pharmaceutical container, and a second series of panels in the form of a folded leaflet attached to one edge of the panel, and a third panel attached to the other edge of the bottom panel. The cover panel contains product identifying indicia on a primary portion as well as an indicated marginal area affixed to the container and separated from the primary portion by a tear line. The marginal area provides a place for the pharmaceutical or chemical manufacturer to place statutory information relating to lot number and expiration date. The leaflet formed of the second series of panels is separated from the first bottom panel by a perforated transverse fold line. The bottom panel contains substantially the same label indicia as the cover panel without the indicated area for the statutory information. The leaflet panels are folded together between the first and third panels.

Abstract: A data communications arrangement for a distributed processor control system having a number of stations which can send and receive control data, includes a communications processor at each station effective for controlling the flow of control data over a serial communications bus. The communications processor is coupled to a dual ported memory device along with a functional processor which is effective for carrying out the actual operations of the process. The communications control processor is further effective for assembling frames of control data according to a predetermined arrangement which gives a timing preference to a first category of data over a second category of data. The assembled frame of control data will then include all of the first category of data and, with time remaining from a timing goal, will include a portion of the second category of data.

Abstract: A communications arrangement for a distributed process control system operable to control an industrial process where different types of data must be communicated between a number of control drops or stations in varying timing priorities includes a first communication channel on which at least two of the control drops are connected. A second communication channel, independent of the first communication channel, accommodates the communication of a type of data that is not as critical in terms of timing as that which is communicated over the first communication channel. All of the control drops are connected to the second communication channel. A control processor, located at each of the control drops, determines the distribution of the types of data between the two communication channels according to a predetermined timing priority.

Abstract: Aquatic plants and their entangled roots can be removed from a lake or other body of water by pulling a lake rake out onto the lake, then pulling the lake rake, with a load of plants and their roots, back in to a central collection site on shore. Multi-purpose teeth of this rake are shaped and positioned to glide across the surface of a lake on the outbound trip, to dig below rooted plants on the inbound trip, and to pass over small crevices or uneven joints on a ramp, truck or trailer at the collection site. Embodiments of the invention may be constructed in a variety of sizes from standard size materials that are commercially available, such as aluminum, steel or plastics.

Abstract: An i/o handler providing communication between a host computer and a plurality of peripheral stations has a abutting member positioned adjacent to the computer and a distributing member removed from the computer. The two members are connected by a communication link with data paths and separate control paths. Communications on the link are by a protocol with synchronized time multiplexed channels and exchange of synchronizing signals in every frame. The handler minimizes the space required at the immediate site of the computer for external communications.

Abstract: A steam generator in an electric power generating system is controlled by controlling turbine steam flow with control signals generated by a programmed digital computer system during startup, synchronization and load operation. The digital computer control signals are generated as a function of monitored turbine system conditions and parameters, the digital computer having means for interrupting the normal computing of the control signals when predetermined operating conditions are monitored. Turbine system parameter signals are periodically scanned and operated on so as to condition them for use in generating the control signals.

Abstract: A distributed processing unit (DPU) or drop which performs process control and data acquisition functions in a distributed processing control system having a data highway linking a plurality of such units. A DPU functional processor accesses the local process I/O interface thereby continually receiving plant information for storage in digital form and subsequent use in the functional processor or for transmission along the data highway. DPU control programs use process values in a transparent fashion, that is without regard to whether these values were obtained through local process I/O interface or via the data highway. The DPU software structure is made up of execution software and support software.

Abstract: A carrier sense multiple access with collision detection strategy ascertains for a particular network configuration the network propagation time, and promulgates a parameter p providing an indication thereof to each station of the network. Each station of the network stores p for use in making decisions about collisions. Whenever a modification of the network is made changing the propagation time, a new value of p is promulgated to the stations of the network so that the collision related decisions made by each stations's interface controller will reflect the new network configuration. Communications are formed in packets with a preamble long enough to propagate the network. The controllers analyze the signals they receive to discern whether a packet has been contaminated by an interference.

Abstract: An electric power plant including a steam generator and a steam turbine is operated by a control system including two redundant digital computers. Switching circuitry is provided for coupling one of the computers through interface equipment to the steam generator and the turbine and a generator according to programmed computer control. A data link is established between the computers to transfer manual/automatic status and other needed data from the control computer to the standby computer. A system is provided for detecting when certain hardware and software malfunctions have occurred and for responsively transferring control to the standby computer. The standby computer is tracked to the control computer so that control computer transfer can be made reliably without disturbing the electric power generation process. The turbine control includes a speed control loop which is implemented with computer operations.

Abstract: Unnecessary fast valving action for load loss protection in a steam turbine generator system induced by partial transducer failure is minimized by the disclosedmethods and apparatus. Upon the occurrence of a mismatch between reheat pressure and electrical output, the interceptor valve is closed momentarily to interrupt the flow of steam to the low-pressure turbine and prevent overspeed. The valve cannot be closed again for a predetermined interval. If the mismatch is not corrected by the one fast valving action, a transducer has failed and further closing of the interceptor valve, except for a full load loss, is precluded until corrective action is taken. The faulty transducer is singled-out by comparing one of the transducer signals with the impulse pressure which is also an indication of the actual operating level of the turbine.

Abstract: A protection system is provided for a turbine plant to avoid double shock or similar rotor blade operation. A digital computer controller detects excessive blade loading conditions on the basis of governor valve positions and effects bumpless mode transfer from sequential valve operation to single valve operation to avoid excessive blade loading.
