  • Patent number: 9317258
    Abstract: Embodiments of the present invention address deficiencies of the art in respect to model validation for modeling tools and provide a novel and non-obvious method, system and computer program product for dynamic validation of models using constraint targets. In an embodiment of the invention, a method for dynamic validation of models using constraint targets can be provided. The method can include defining constraint targets on object validation in a model within a MDD tool to object instances affected by a change in another object in the model, detecting a change in an object instance in the model in the MDD tool, and validating only other object instances in the model that are affected by the detected change.

  • Publication number: 20090261965
    Abstract: Apparatus and method for managing utilization of rooms in a clinic, for example, include a visible display, for example, colored lights at an examining room, indicating one or more of several available room status values for the room. An input device including, e.g., push buttons, is coupled to the display and adapted for selecting the room status value. A timer coupled to the input device and display automatically changes the status value of a room when a predetermined time period has elapsed after the status value is first selected, except when a third room status value is selected. This feature notifies personnel if, for example, a patient has been left alone in a room too long. A central control provides a database to accumulate minute-by-minute utilization data of the clinic rooms and also programs to access and compute from the data the overall utilization by variable periods. This utilization data are useful for planning, reallocation and investment in new space.

  • Patent number: 6150589
    Abstract: Novel B.t. genes encoding toxins active against lepidopteran insects have been cloned from a novel lepidopteran-active B. thuringiensis isolate P515862. The DNA encoding the B.t. toxin can be used to transform various hosts to express the B.t. toxin.

  • Patent number: 5862177
    Abstract: A method for testing communication channels of a satellite using a 16-bit n-length compression algorithm wherein the most significant bit (MSB) is used to represent the errored or not errored condition of the compression algorithm. Error patterns are read and downloaded into a PC interface card which decompresses the file real time and passes the error pattern to a bit error rate summer board. The bit rate summer board overlays the error pattern onto the communication links of the satellite which causes precise bits to be errored accordingly.

  • Patent number: 5268172
    Abstract: A novel B.t. toxin gene toxic to lepidopteran insects has been cloned from a novel lepidopteran-active B. thuringiensis microbe. The DNA encoding the B.t. toxin can be used to transform various prokaryotic and eukaryotic microbes to express the B.t. toxin. These recombinant microbes can be used to control lepidopteran insects in various environments.
