Abstract:
A medical fluid delivery system includes a dialysis instrument; a disposable pumping cassette operable with a pumping actuator of the dialysis instrument, the disposable cassette including or connected fluidly to a plurality of first connectors; a plurality of second connectors configured to interface with the first connectors, each second connector associated with a radio frequency (“RFID”) tag; and electronics configured to read the RFID tags via a plurality of antennae and to identify that each of the second connectors is positioned properly with respect to a proper one of the first connectors.
Abstract:
In one embodiment, the invention includes a controller that interrupts a CPU based on a counter that uses a decrement step which may increase as high priority data packets are received by the controller.
Abstract:
A method of making a reverse progressive lens has the steps of selecting a standard progressive lens having a distance zone, a transition zone and a near zone; selecting an add determination that is double or more than double in power; reversing the regular progressive lens by orienting it upside down; and cutting away the near zone so that the transition zone becomes the new near zone. To maintain convergence of the corridor channel, one by orders the OS lens with the OD power and the OD lens with the OS power. The method also includes measuring a distance PD, measuring the segment height and keeping the same cylinder axis such that rotating the lens 180° does not change the axis position. Selecting a standard progressive lens may include one with a distance zone, a corridor/transition zone and a near zone.
Abstract:
A wind generator having removable change-out bearings includes a rotor and a stator, locking bolts configured to lock the rotor and stator, a removable bearing sub-assembly having at least one shrunk-on bearing installed, and removable mounting bolts configured to engage the bearing sub-assembly and to allow the removable bearing sub-assembly to be removed when the removable mounting bolts are removed.
Abstract:
A system for protecting superconducting generator field coils including a controller configured to monitor for a quenching of a superconducting field coil of a generator and control a dissipation of a current flow in the superconducting field coil in an event of the quenching, and an armature coil of the generator configured to cause the dissipation of the current flow in the superconducting field coil responsive to the controller in the event of the quenching of the superconducting field coil. A method for protecting superconducting generator field coils including monitoring for a quenching of a superconducting field coil of a generator, and dissipating a current flow in the superconducting field coil via an armature coil of the generator in response to a detection of the quenching.
Abstract:
A permanent magnet rotor assembly includes a rotor and a plurality of permanent magnet pole assemblies positioned against the rotor. Each of the permanent magnet pole assemblies includes a magnetic block and an encapsulating member that completely encapsulates the magnetic block.
Abstract:
A system for controlling torque ripple in a permanent magnet synchronous machine includes a power converter configured to be coupled to the permanent magnet synchronous machine and to receive converter control signals and a system controller coupled to the power converter. The system controller includes a fundamental current controller configured for providing fundamental voltage commands, a harmonic current controller configured for using harmonic current commands, current feedback signals from the permanent magnet machine, and fundamental current commands in combination with positive and negative sequence regulators to obtain harmonic voltage commands, and summation elements configured for adding the fundamental voltage commands and the harmonic voltage commands to obtain the converter control signals.
