Abstract: The invention relates to a heat exchanger for a hot fuel cell. The heat exchanger includes a first flow circuit for receiving a cool air stream and a second flow circuit for receiving a hot fluid coming from the cell, the first and second flow circuits having common surfaces for heat exchange. In accordance with the present invention, each of the first and second flow circuits comprises a plurality of concentric annular ducts that are interconnected. The two walls of each duct are mechanically decoupled from each other, thereby enabling them to expand independently of one another and avoiding mechanical stresses within the heat exchanger.

Abstract: A buckling restrained brace includes a deformable core contained within an outer casing. Ends of the core protrude from the casing for connection to a frame or other structure. A length of the deformable core between its ends, referred to as the gauge or yielding section, is capable of deforming during an earthquake or blast loading. The gauge section is differentially heat treated from the ends so that the gauge section has a lower yield strength than the ends. The casing provides containment of the core to prevent buckling of the core. A metal foil interface or unbonding layer is provided between the deformable core and the casing so that the deformable core does not bind to the casing. The buckling restrained brace provides significant performance improvements over prior art BRBs coupled with simplified assembly.

Abstract: An annular combustion chamber has an inner wall and an outer wall of ceramic matrix composite material, together with a chamber end wall that is connected to the inner and outer walls. Elastically-deformable link elements connect the inner wall and the outer chamber walls to inner and outer metal casings. Each of the inner and outer chamber walls is subdivided circumferentially into adjacent sectors along longitudinal edges, each sector extending continuously from the end wall to the opposite end of the chamber and being folded outwards from the chamber at each of its longitudinal edges to form a portion having a U-shaped cross-section terminated by a folded-back margin that is spaced apart from the outer face of the corresponding chamber wall. The link elements are connected to the inner and outer chamber walls by being fastened to the sector margins.

Abstract: An interface is provided that configures itself dynamically based on sensor information received from a sensor assembly or actuator information received from an actuator assembly. The interface may be configured to interoperate with sensor assemblies including analog transducers, smart transducers providing digital outputs and various actuators. The sensor information or the actuator information may include information for managing power consumption associated with the operation of the sensor or the actuator. Using the sensor information or the actuator information, a power management scheme may be implemented to reduce power consumption and extend the operational time of a module. The sensor information also includes information about the sensor signal generated by the sensor. The information about the sensor signal allows the module to interoperate with more diverse types of sensors.

Abstract: The preferred embodiments of the present invention are directed at a device that provides a reliable, accurate and quantifiable measure of a patient's edema. The device improves on the current method of digital manipulation by evaluating the pitting phenomena in a user-independent manner. The output of the device allows a physician to categorize edema into at least ten different levels of severity. The systems of the present invention provides the ability to distinguish between tissues of varying viscosity.

Abstract: An ion discharge gyroscope measures rotational motion and linear acceleration by generating symmetrical ion jet streams and measuring respective amounts of the jet streams impinging on detectors located so as to intercept the ion jet streams. The ion jet streams will be diverted by operation of the Coriolis effect and the differences in the amount of each ion jet stream impinging on the detectors is an indication of rotational motion and linear acceleration. In one embodiment, the ion jet streams are heated and the respective temperatures of the detectors are measured. In another embodiment, the amounts of current flowing through each detector, as contributed by the ion jet streams, are measured and used to determine rotation and acceleration.
