摘要： A control circuit for a heating system having a gas burner assembly, a heat absorbing coil, a heat releasing coil, a circulating pump for pumping a hydronic fluid between the two coils, and an air blower for the heat releasing coil is disclosed. The control circuit includes a thermostat located in the space to be heated and a first relay switch which electrically connects the circulating pump in response to a signal from the thermostat. A combustion safety control is electrically connected to the thermostat, a main gas valve, and a flame sensor such that the main gas valve is open in response to a signal from the thermostat and the main gas valve is closed where no signal is received from the thermostat or an insufficient signal is received from the flame sensor. A second relay switch is electrically connected to the air blower, the circulating pump, and a hydronic fluid temperature sensor such that in response to a signal from the fluid temperature sensor the air blower and the circulating pump are electrically connected. After the thermostat ceases to send a signal to the first relay switch, the second relay switch acts to electrically connect the air blower and the circulating pump so long as the temperature of the fluid is sufficient to provide heat to the space to be heated. A number of safety features are also provided.

摘要： The location of a termination in a properly terminated LAN can be remotely detected. The cable's skin effect produces a detectable signature at the sending-end when a step function, for example, reaches the termination. Accordingly, a network analysis device is connected to the network to inject the step function onto the network cabling. The voltage response of the cabling to this is first digitally sampled and then analyzed in a system controller. The system controller reviews the sampled data for an inflection point and then locates the termination by reference to the delay between when the signal was placed on the cable and the detection of the inflection point.

摘要： A method for performing time domain reflectometry contemporaneously with recurrent transmissions, such as idle transmissions, on a computer network, such as a 100 BASE T protocol network is disclosed. This method comprises detecting the recurrent transmissions and then storing representations of those transmissions. A probe signal, such as a TDR signal, is then generated onto the computer network during the recurrent transmissions. A response of the network to the probe signal combined with the recurrent transmissions is then detected. The signal transmission characteristics of the network are then analyzable based on the response to the probe signal using the stored representations of the recurrent transmissions, using deconvolution, for example.

摘要： A method and system for computer network physical layer analysis is describe using signal analysis techniques and beginning with time-domain responses to yield highly quantitative analysis of the computer network's physical layer. Specifically, multiple transmissions are accumulated into a composite response of the computer network link. This composite response is then used as the basis for analysis of the computer network link. Further, an automated process is described for location of an arbitrary termination of a link.

摘要： A cross-connect panel for a computer network is disclosed that provides a mechanism for connecting to the signal transmission media of the network. In the typical scenario, the inventive cross-connect panel replaces the common cross-connect panel that receives the various cables running between the remote nodes and the hub, switch, or other network communications device. The panel has a series of panel-node connectors that are adapted to receive the signal transmission media from the network nodes. The cross-connect panel also has panel-device connectors that in most embodiments will be of a standard type to connect to the network communications device. The panel-node connectors and the panel-device connectors are electrically interconnected to each other via a backplane to complete the communications links. The panel further includes a monitoring port that is also preferably connected to the backplane to provide physical layer access to the communications links. In this way, a network monitoring device interfacing with the port may be connected directly to the network's communications links or disconnected when monitoring is not necessary.

摘要： Disclosed herein is a method and apparatus for preventing the rotation of a stud member during preloading. The apparatus comprises a stud member having a shaft portion extending into the member to be clamped and a hex or double hex portion carrying a locking nut. Extending outward from the hex or double hex portion of the stud there is a threaded portion carrying a nut which is torqued to preload the stud. Between the locking nut and the member to be clamped is a locking ring which engages the locking nut to prevent the stud from rotating during preloading.Also disclosed is a method of preloading a stud without the use of an external restraint to prevent the stud from rotating when a torque is applied.

摘要： A network diagnostic device is disclosed that digitally samples the voltages on the cabling of the network, but does so at a much higher rate and with greater resolution then is required to minimally detect digital transmissions on the cabling. This sampling provides information on the analog characteristics of digital, noise, and interference signals on the network. Thus, network problems can be precisely diagnosed. The device includes a fast digitizer with a long memory and a system processor that statistically analyzes the signal events captured by the digitizer. The invention is also capable of performing time domain reflectometry (TDR) analysis of a functioning network. This is accomplished by placing a TDR signal on the network surrounded by a transmission that the network devices will interpret as a broadcast diagnostic packet. This will cause the network nodes to ignore the transmission. The digitizer, however, is able to detect the networks response to the TDR signal. Methods for identifying unknown network sources and Manchester decoding are also disclosed.
