  • Publication number: 20230137671
    Abstract: A computer-implemented method for concept matching using a machine learning model, may include: receiving, from a user, a search query comprising: at least one criterion that represents at least one concept; inputting the received at least our criterion into at least one neural network for processing the search query; determining, using the at least one neural network, the at least one concept represented by the at least one criterion; retrieving, from a storage, at least one data item winch matches the determined at least one concept, through a cross-modal data retrieval method of retrieving a data type different from an input data type; and outputting the retrieved at least one data item in response to the search query.

  • Patent number: 8586318
    Abstract: The present invention is directed to restricted access media (RAM), methods for preparing restricted access media, and kits for preparing restricted access media that contain protected ligand binding agents or protected enzymes. Certain RAM provided contain a plurality of protected regions of the support that contain ligand binding agents that are protected by blocking agents. Certain RAM provided contain a plurality of protected regions of the support that contain unbound ligand binding agents or enzymes that are retained in the protected regions by a capping agent. Methods of making the RAM of the invention and associated kits are also provided.

  • Patent number: 7575908
    Abstract: A method and kit for immobilization of a glycoprotein. The method may include activating an affinity support. The affinity support may be activated by reacting the affinity support with a compound that is reactive with one or more functional groups included within the glycoprotein. The method may also include oxidizing the glycoprotein in which oxidation conditions are selected to yield an oxidized glycoprotein that is biologically active and contains a sufficient number of reactive aldehyde groups for coupling to a support. For example, the oxidized glycoprotein may include five reactive aldehyde groups. In addition, the method may include reacting the oxidized-glycoprotein with the activated affinity support to immobilize the glycoprotein.

  • Publication number: 20070021887
    Abstract: A system and a method for controlling a yawing moment actuator (8) in a motor vehicle, having the process steps of detecting the current steer angle of the motor vehicle; determining the current coefficient of friction between the tire of the motor vehicle and the road; detecting the current driving speed of the motor vehicle; defining a desired curve as a function of the current steer angle, of the current coefficient of friction and of the current driving speed, which represents a connection between the steer angle and a desired lateral acceleration (ay desired) at a predetermined coefficient of friction, and adjusting the yawing moment of the yawing moment actuator (8) such that the resulting current total lateral acceleration of the motor vehicle is regulated to the desired lateral acceleration (ay desired) assigned to the current steer angle according to the defined desired curve.

  • Patent number: 6128757
    Abstract: A method for improving the fault coverage of functional tests for integrated circuits by establishing a design-specific low voltage functional screening procedure. In the disclosed embodiment of the invention, a reduced voltage test threshold is established by comparing the results of an iterative test procedure executed on a set of known good integrated circuits and integrated circuits which have passed traditional functional test programs but manifested problems in the field. For a given device under test, the iterative procedure commences by applying a system clock and nominal power supply voltage. A set of functional test vectors is then executed on the device using automated test equipment (ATE). The results are compared with expected test results to determine if the device is a passing device under the initial test conditions. If so, the power supply voltage is decremented by a predetermined value and the test process is repeated.
