A parallel fixed-point square root and reciprocal square root computation uses the same coefficient tables as the floating point square root and reciprocal square root computation by converting the fixed-point numbers into a floating-point structure with a leading implicit 1. The value of a number X is stored as two fixed-point numbers. In one embodiment, the fixed-point numbers are converted to the special floating-point structure using a leading zero detector and a shifter. Following the square root computation or the reciprocal square root computation, the floating point result is shifted back into the two-entry fixed-point format. The shift count is determined by the number of leaded zeros detected during the conversion from fixed-point to floating-point format.

Techniques for evaluating a second version of software. Embodiments selectively route incoming requests to software instances within a plurality of baseline instances and a plurality of canary instances, where the baseline instances run a first software version and the canary instances run the second software version. The software instances are monitored to collect performance data for a plurality of performance metrics. Embodiments calculate aggregate baseline performance metrics, where each of the aggregate baseline performance metrics is calculated based on the collected performance data for the plurality of baseline instances. For each of the performance metrics and canary instances, embodiments calculate a relative performance value that measures the collected performance data for the respective canary instance and for the respective performance metric, relative to the corresponding aggregate baseline performance metric. A final measure of performance is calculated for the second version of software, based on the relative performance values.

A method and device for establishing a protocol relating to a measurement sequence for controlling a magnetic resonance tomography system, the measurement sequence is segmented into various groups of partial modules that are similar to one another. A partial module that potentially generates the greatest physiological exposure for a patient is identified. Furthermore, a test is carried out by means of a model function to determine whether physiological limiting values are being observed in the measurement sequence for the partial module. If the physiological limiting values are not being observed, parameters influencing the measurement sequence are modified and the preceding test step is repeated.

To provide a magnetic sensor circuit which does not output spike-like voltage errors to a signal processing circuit. A magnetic sensor circuit is provided which is configured so as to output an output signal to a signal processing circuit through a plurality of hall elements driven by a first switch circuit and a second switch circuit controlled by a second control circuit and in which the first switch circuit controls timings at which spikes occur in the output signal of each of the hall elements in such a manner that the timings are not the same, and the second switch circuit selects and outputs an output signal having a period of a timing free of the occurrence of a spike.

A DC level detection circuit between high speed signal line connecting ports and a system using the same in optical communications is disclosed. Corresponding ports of a high speed signal line each have an additional resistor, where one additional resistor has a resistance significantly greater than that of the other resistor. The smaller resistor is grounded. The larger resistor is connected to a DC voltage source, a low pass filter, and a signal detection port. Thus, when both ports of the high speed signal line are connected, a status of the electrical level detected at the signal detection port changes. The circuit detects the connection state of the high speed signal line without negative effects on signal transmission and is applicable to various circuits, especially plug-in modules and corresponding slots. Thus, the circuit further enables signal port multifunctionality, increases module installation accuracy, and provides higher compatibility for plug-in modules.

A system, method, and apparatus are described for monitoring the operation of a three phase system. In some embodiments, one or more vectors may be generated. The vectors may be indicative of an output of the three phase system. In some embodiments, one or more of the vectors may correspond to a difference of two of the three phases of the three phase system. A gain associated with a third of the vectors may be different from a gain associated with each of the first and the second vectors. The gain associated with the third vector may be maximized. The three vectors may be combined with hardware or software. In some embodiments, frequency content associated with the three phase system may be filtered with hardware or software. For example, filtering may be used to remove frequencies outside of a specified frequency range of interest.
