摘要： A robot link deflection gauge providing precise measurement of the deformation of a robot link due to load and acceleration forces. The robot link deflection gauge of the present invention includes at least one light source, a plurality of lenses and corresponding position sensitive detectors positioned at the ends of the robot arm link to accurately measure the relative position and orientation of a first (or destination) end relative to a second (or source) end of each robot arm link. Each lens has an optical axis which is positioned to receive light from the light source and focus the light into a light spot on the surface of the corresponding position detector. As the robot link is deformed so that the destination end is displaced and rotated relative to the source end, the light is transmitted away from the optical axis of each lens causing the light spot to be displaced along the surface of the respective position sensitive detector. The position sensitive detectors convert the light spots into electrical signals to provide a measurement of the displacements of the light spots relative to a predetermined origin. These displacements are converted to the relative X and Y displacement, rotation, and pitch and yaw of the destination end with respect to the source end.

摘要： A magnetic field sensor device suitable for use in an implantable medical device (such as a pacemaker, cardioverter/defibrillator, or cardiac resynchronization therapy device) is able to detect magnetic fields, such as the fields generated by a Magnetic Resonance Imaging (MRI) device, over a wide measurement range and to discriminate between different field strengths. Multiple sensors provided within the magnetic field sensor device are optimally biased to provide a power saving solution which is accurate enough for medical devices applications. The output of the magnetic field sensor device can be used to switch the implantable medical device to different operational modes, e.g., between programmable and “MRI safe” modes.

摘要： A hybrid vehicle includes an internal combustion engine, an electric motor/generator and a battery. The drivetrain includes a planetary gear in which the engine is coupled to the sun gear, the motor/generator to the ring gear and the vehicle wheels to the carrier of the planetary. A controller switches the vehicle between electric, assist, charge and regenerative modes of operation and substantially decouples the engine speed from the vehicle speed, enabling the engine to operate at peak efficiency. Additional overdrives are included to enable the engine to operate at optimum speed in the various modes of operation.
