  • Patent number: 7239396
    Abstract: This invention relates to a method and apparatus for measuring the phase change of an output optical signal from a device. In one embodiment an input optical signal is split into first and second optical signals, and the first optical signal is passed through the device while applying an external stimulus to the device, to produce an output optical signal having a phase shift. The carrier frequency of the second optical signal is changed, and the output optical signal and the changed second optical signal are then combined. The combined signal is detected in accordance with the external stimulus applied to the device, and the phase change of the output signal of the device is measured as a function of the external stimulus applied to the device.

  • Patent number: 7171972
    Abstract: This invention provides a thermal energy system comprising a heat exchanger for transferring thermal energy between a source and a load, the heat exchanger having a primary side associated with the source, and a secondary side for conducting a fluid associated with the load, wherein the secondary side of the heat exchanger is passively back-flushed upon consumption of a portion of the fluid. Passive back-flushing prevents fouling of the heat exchanger due to sediments, scale,and mineral deposits which may be present in the circulating fluid.

  • Publication number: 20070015737
    Abstract: Methods and compositions which are useful in the treatment of amyloidosis. In particular, methods and compositions are provided for inhibiting, preventing and treating amyloid depositions, e.g. in pancreatic islets, wherein the amyloidotic deposits are islet amyloid polypeptide (IAPP)-associated amyloid deposition or deposits. The methods of the invention involved administering to a subject a therapeutic compound which inhibits IAPP-associated amyloid deposits. Accordingly, the compositions and method of the invention are useful for inhibiting IAPP-associated amyloidosis in disorders in which such amyloid deposition occurs, such an diabetes. The invention also provides a process for the preparation of cells suitable for transplantation into a mammal, which cells are capable of forming fibrils, said process comprising contacting the cells with an inhibitor of fibril formation. In particular the process prepares cells for use in a method of treating diabetes.
