摘要： Methods and systems are generally described for measuring a voltage used by an imaging system to generate radiation used in imaging. In embodiments, different datasets are acquired using different degrees of attenuation of the radiation. The differently attenuated datasets are processed to derive a ratio of the differential attenuation. The attenuation ratio is processed to derive a measure of the voltage used by the imaging system to generate the radiation used to acquire the different datasets.

摘要： A shoot-through protection system for an electric power generating system including a synchronous generator, a bridge rectifier coupled to an output of the generator for converting alternating current (AC) from the generator to direct current (DC) at a rectifier output, and at least one inverter coupled to the rectifier output for converting the DC output to a controlled frequency AC output for application to a load. The generator has a separately excited field winding in which the magnitude of field excitation controls the voltage output of the generator. A microprocessor-based controller regulates generator field excitation in a manner to control the DC output of the rectifier. The generator is protected from a shoot-through in the inverter by detecting a sustained voltage drop in the rectifier DC output and reversing generator field excitation in response to such a voltage drop to rapidly drive generator output voltage to substantially zero volts.

摘要： A self-test system for a shorted diode protection circuit in an electric vehicle propulsion system includes a series of relays for selectively coupling a battery in circuit with a field winding of a generator, the shorted diode protection circuit being coupled in voltage sensing arrangement with the field winding. The relays are operated to induce current in forward and reverse directions through the winding in separate test stages. At each stage the winding is disconnected from the battery so that inductive reactance creates a voltage on the winding to actuate the protection circuit. A system controller records whether the protection circuit is responsive and therefore operable and alerts a vehicle operator.

摘要： A system and method for controlling thermal output of a medical device is disclosed. A thermal controller receives operational parameters for an impending use of a medical device and predicts a thermal output of the medical device from the operational parameters. The thermal controller compares the predicted thermal output to a desired limit on thermal output and, if the predicted thermal output exceeds the desired limit on thermal output, dynamically controls power consumption by the medical device to maintain an actual thermal output substantially at or below the desired limit on thermal output during use of the medical device.
