  • Patent number: 8456644
    Abstract: Deformations of a surface of a test object can be measured by attaching mirrors to a surface of a test object, each mirror having a reflective surface with a dimension and a radius of curvature smaller than those of the surface of the test object. Light is directed towards the mirrors and a reference surface, and interference patterns are generated using light reflected from the mirrors and the reference surface. Changes in the surface of the test object are determined based on the interference patterns.

  • Patent number: 7410765
    Abstract: The present invention provides methods and materials that can be used to detect, examine and exploit protease mediated protein expression. An illustrative embodiment of the invention is a polynucleotide encoding a polypeptide having a plurality of operatively linked elements comprising a polypeptide degradation signal that functions as a proteosome substrate; a polypeptide of interest having an observable activity; and a linker disposed between the polypeptide degradation signal and the polypeptide of interest. The linker comprises a protease recognition motif that is capable of being specifically recognized and cleaved by a protease. The activity of the polypeptide of interest is observed when the motif is specifically recognized and cleaved by the protease; and the activity of the polypeptide of interest is decreased or not observed when the motif is not specifically recognized and cleaved by the protease.

  • Patent number: 7282563
    Abstract: Genes encoding opioid receptors (including opioid-like receptor (ORL) proteins) can be retrieved from vertebrate libraries using the murine probe disclosed herein under low-stringency conditions. The DNA sequence shown in FIG. 5 or its complement can be used to obtain the human delta, kappa and mu genes as well as the murine mu gene and human ORL-1. The probe provided encodes the murine delta opioid receptor.

  • Patent number: 7073485
    Abstract: An engine management system for an internal combustion engine, which has at least one cylinder pressure sensor and at least one engine actuator, includes a data processor arranged to receive and process cylinder pressure data from the cylinder pressure sensor and the actuator controller arranged to control the actuator to optimize engine performance based on the processed data, in which the cylinder pressure data is obtained during a performance optimized engine cycle or cycles. The processor processes the data to construct a cylinder pressure variation function for the engine cycle or cycles and derive control data therefrom for the actuator controller.
