In one embodiment, the system includes: (1) a generic OPC compliant interface object and (2) a template associated with the generic OPC compliant interface object. The template is modifiable and combinable with a device-specific interface portion to yield the device-specific noncompliant user application. The device-specific noncompliant user application is dynamically linkable with and aggregates to the generic OPC compliant interface object to yield the OPC compliant data server.

Abstract: The present invention is a portable electronic video display. The display is configured to be worn on the arm or wrist of a user, or stored in a pocket or backpack. The display is raised to eye level and the user looks through an eyepiece to view the video display. Control buttons are located on the display for generating point and click type commands. The display is meant to be used remotely from a computer. The computer could be worn or carried by the person or simply be free standing, some distance away. The computer is configured to convert video signal into a serial data stream and then transmit that stream via an RF signal. The display then receives that signal and converts it back into a video signal, displaying it on a miniature electronic video display. That image is them magnified through various optics to present a final image to the user. The point and click commands are separately transmitted back to the computer, where they are received and acted upon.

Abstract: Process control methods and apparatus for controlling batch processes including batch heating processes. The present invention includes iterative learning control (ILC) techniques to provide improved run-to-run process control. One method provides a desired temperature profile over the length of a batch time period. This method gathers historical measured value data over the length of a first batch run which can be converted to deviation or error historical data, as well as a historical output history of outputs provided to control the process for the first run. The historical deviation and output histories from the first run can then be used to generate the output profile for a second batch run. Thus, the outputs from a first batch, such as the output to a local heater control, together with the deviation or error history from the first batch run, can be added to the output value provided during the previous batch to generate new output value to be used to control a second batch run.

Abstract: A method and system compares combinations of vehicle or aircraft state variables against known combinations of potentially dangerous states. Alarms and error messages are selectively generated based on such comparisons. In one embodiment, pairs of aircraft state variables are selected and compared to known undesirable pairs of state combinations that indicate an error or a condition that a crew should monitor closely. The combinations and error messages are provided by the database. The comparisons are conducted on a periodic basis monitoring real time states of the parameters collected from various sensors and commands. Experts considering a matrix that provides an exhaustive pairwise comparison of potentially important state variables initially identify undesirable state combinations. Error messages and identification of potential alarms are generated based on both knowledge of actual accidents, and on use of expert knowledge to predict potentially dangerous states.

Abstract: Light is polarized in perpendicular directions between a source of light and a users viewing of information on a display device. A first sheet of polarized material is placed at the source of the light, such as a window in a cockpit. A second sheet of polarized material is attached or integral to a display device. The pass axis of the second sheet is oriented substantially perpendicular to pass axis of the first sheet.

Abstract: A workflow management system utilizes tokens associated with work flowing through paths of activities or tasks under control of constructs. The token is representative of the path taken to reach the current activity. Tokens are given attributes for activities and constructs, such as token value and construct IDs. Rules are defined for activities and constructs to use when receiving, modifying and passing on the tokens. The rules in one embodiment comprise algorithms for comparing tokens, consuming tokens, appending tokens, and generating tokens. The tokens provide the ability to control flow of the work, such as sequencing, paralleling, iterating and synchronizing activities.

Abstract: A system and method compares combinations of vehicle variable values against known combinations of potentially dangerous vehicle input signal values. Alarms and error messages are selectively generated based on such comparisons. An aircraft signal definition is provided to enable definition and monitoring of sets of aircraft input signals to customize such signals for different aircraft. The input signals are compared against known combinations of potentially dangerous values by operational software and hardware of a monitoring function. The aircraft signal definition is created using a text editor or custom application. A compiler receives the aircraft signal definition to generate a binary file that comprises the definition of all the input signals used by the monitoring function. The binary file also contains logic that specifies how the inputs are to be interpreted. The file is then loaded into the monitor function, where it is validated and used to continuously monitor the condition of the aircraft.

Abstract: A method for adjusting a plurality of controlled subsystems in a building or plant that facilitates cooperative energy usage with a utility provider. By referring to a single profile of adjustments that correspond to changes in the value of a utility signal and distributing this to each relevant controller for each subsystem, a single setback delta can be applied to each subsystem for each change in utility signal value (i.e., pricing information). Alternatively, multiple profiles can be used to provide for firmer control and thereby allow for different zones to respond differently to a single change signal sent by the utility provider.

Abstract: A remote viewing system for simulating the views from a window includes a camera assembly and a remote viewing assembly. The camera assembly obtains views of a site and transmits the views to the remote viewing assembly. The viewing assembly then displays the views to simulate the various perspectives which can be obtained from looking out of a window, such as looking up and down out of the window.

Abstract: Methods, functional data, and systems are provided for image feature translation. An image is decomposed into sub images, each sub image having its features identified by feature attributes. The feature attributes are used to identify a particular feature within each sub image. The orientation of the particular feature within the sub image is then mapped or calculated to a value. One or more of the mapped or calculated values are translated into a reading associated with an instrument. The reading is then optionally recorded or transmitted.

Abstract: Methods, data, and systems are provided to warp an image. Input pixels associated with an input image are warped according to a provided or obtained warping function. A single weight is assigned to each input pixel. The weight represents each input pixel's horizontal and vertical dimensions within an output lattice. The single weight is combined with an intensity value associated with each input pixel to map each input pixel to the output lattice in a single processing pass.

Abstract: A compensation circuit is disclosed for compensating bias levels of an operational circuit in response to variations in a supply voltage. The compensation mechanism identifies variations in the supply voltage by comparing the voltage of a selected node of the operation circuit with a relatively constant or fixed reference voltage. Based on the results of the comparison, the compensation mechanism adjusts selected bias levels in the operational circuit, preferably using current stealing circuitry, so that the functionality and performance of the operational circuit can be substantially maintained. A biasing circuit for biasing one or more differential pairs is also disclosed.
