Abstract:
A testing system for, and method of, simulating signal flow through a logic block pattern of a real time process control system. The system includes: (1) a memory that contains a data base of input data associated with simulated sensors and a rule base containing control rules and constituting a logic block pattern and (2) a processor that operates in an arbitrary time base to apply the input data to the control rules to simulate signal flow through the logic block pattern and thereby produce simulated output data and real time control system responses thereby testing the logic block pattern, the memory and the processor being detached from the real time process control system to prevent use of resources thereof in connection with the logic block pattern testing.
Abstract:
A system which comprises: a graphical tool which is capable of building batch or phase sequential steps and a smart device control (5) for input/output device control; a microprocessor (9) which is capable of running the phase sequential steps; and an I/O communication processor (24) which is capable of communicating the phase sequential steps to the input/output device (13).
Abstract:
A method constrains the number of displays which are simultaneously available to an operator on a display surface in a multi-windowed computer environment. Each display is displayed having predetermined display characteristics, including position and size, such that each display is in an assigned window which is a unique area of the display surface. The method comprises the steps of determining the display characteristics of a first application display which is about to be displayed. If a second application display is already being managed with the same display characteristics, the second application display is closed while maintaining the display characteristics from the first application display. The first application display is launched for display and is displayed in the same position as the closed second application display, thereby constraining the number of displays.
Abstract:
A method for constraining the available display surface in which an application display is displayed includes a display surface being divided into a predetermined number of windows. Each window is defined to have a unique area of the display surface and is assigned to a predetermined category of display. The method comprises the steps of modifying an application display in response to an input to modify the display. The modified display is verified to assure that the modified application display complies with specified parameters contained in a configuration file. The configuration file includes sizes and position parameters. If the modified application display does not comply with the specified parameters, the modified application display is changed to conform with the parameters of the configuration file and outputted for display.
Abstract:
A method of controlling a computer window display of a display system having a display surface of one or more physical screens, provides an integrated workspace wherein multiple applications are displayed, by category, in a coordinated, predetermined area of the display surface. In response to a request inputted to the display system, the requested application display is created. A category of the requested display is ascertained. A lookup is performed in a configuration file to find a match between the category of the requested display and an entry in the configuration file. When a match of categories is found, the display characteristic data is obtained to get the position and size of the display. A pointer points to the next available area of the display area for the category of interest, and the display is created to be positioned within the selected available window.
Abstract:
Disclosed is a hermetically sealed housing assembly for protecting electrical equipment. The housing assembly includes a hermetically sealed housing member having an exterior wall and an interior region for containing the electrical equipment. A flex tap electrical signal conductor extends through an opening in the exterior wall, and transmits electrical signals between the electrical equipment in the interior region and electrical components in a region exterior to the housing member. The flex tape signal conductor is hermetically sealed to the exterior wall of the housing member at the opening to maintain the integrity of the hermetic seal of the housing member even after temperature-cycling for a period of time.
Abstract:
A CMOS output driver circuit (10) with p-channel substrate tracking provides an output driver to full power supply voltage (VDD). The circuit (10) is especially useful as a redundant circuit where its power supply connection (VDD) is connected to ground (VSS) and the circuit (10) is kept in unbiased storage until it is needed.
Abstract:
In a magnetoresistive random access memory device, a spacer material is deposited at the edges of a memory bit to maintain magnetization at the edges in a direction along the edges.
Abstract:
An apparatus for correcting errors in information read from a memory unit, comprises a first and second memory, where primary and backup information are stored in predetermined addressable locations. The primary information and the backup information in corresponding locations are the same. A processor, commands a read of information stored in the memory unit, the read being a simultaneous read of the primary information and the corresponding backup information. A multiplexer, couples the output ports to the processor. The primary information read from the first and second memory and the backup information read from the first and second memory are coupled to the multiplexer. The first and second memory each indicate via a respective first and second error signal if an error is detected on the information just read from the first and second memory, respectively. Select logic determines whether the data in the first and second memory contains the primary or the backup information and generates the control signal to select the set of input ports to be the output of the multiplexer. The control signal selects the primary signal to be coupled to the processor if no error is indicated in the primary copy and selects the backup information to be coupled to the processor if an error is indicated in the primary copy and not the backup copy.
Abstract:
Disclosed is a fault-tolerant and/or fail-safe information processing system architecture for handling information from a plurality of independent subsystems which provide information related to selected input quantities, and which includes a plurality of redundant information processors for deriving specific processor output data as a function of the selected subsystem input quantities.
