Abstract: A vehicle with an N-phase electric motor, with a first onboard electrical subsystem and with a second onboard electrical subsystem, wherein the electric motor includes a rotor and a stator system, and the first onboard electrical subsystem includes an inverter. The stator system is associated with the inverter and the electric motor is operable with an inverter controller according to the principle of field-oriented control such that the stator system is embodied in a star circuit in which the star point can be connected to the second onboard electrical subsystem directly or via a star point switch. The inverter controller includes a current controller and a star point controller, wherein the current controller controls phase currents of the stator system and the star point controller controls a star point current.

Abstract: An apparatus comprising a transmission line, a receiver circuit, and a high pass filter circuit coupled between the transmission line and a receiver circuit input. The receiver circuit is configured to receive a data signal over the transmission line at a first data rate. The high pass filter circuit is connected between the transmission line and a receiver circuit input and has a corner frequency that is less than approximately the first data rate and is greater or equal to than approximately one-half the second data rate. The second data rate is an effective data rate caused by an expected data pattern on the transmission line. Other devices, systems, and methods are disclosed.

Abstract: An apparatus comprising a first multiplexer circuit (MUX) to receive a plurality of clock phase signals at a corresponding plurality of MUX inputs and to output a first clock signal and a second clock signal that are out of phase with each other, a phase delay circuit to receive the output of the first MUX and to generate adjusted first and second clock signals that have reduced phase error with respect to detected edges of incoming data, an output MUX to receive the adjusted first and second clock signals and to output a recovered clock signal, and a control circuit coupled to output MUX select inputs. The control circuit includes logic circuitry to select the first adjusted clock signal as the recovered clock signal and to select the second adjusted clock signal as the recovered clock signal when the first adjusted clock signal nears a phase limit due to drift of the detected data edges. Other devices and methods are disclosed.

Abstract: A memory daughter card (MDC) is described, having a very high-speed serial interface and an on-card MDC test engine that allows one MDC to be directly connected to another MDC for testing purposes. In some embodiments, a control interface allows the test engine to be programmed and controlled by a test controller on a test fixture that allows simultaneous testing of a single MDC or one or more pairs of MDCs, one MDC in a pair (e.g., the “golden” MDC) testing the other MDC of that pair. Other methods are also described, wherein one MDC executes a series of reads and writes and other commands to another MDC to test at least some of the other card's functions, or wherein one port executes a series of test commands to another port on the same MDC to test at least some of the card's functions.

Abstract: A memory controller and method that provide a read-refresh (also called “distributed-refresh”) mode of operation, in which every row of memory is read within the refresh-rate requirements of the memory parts, with data from different columns within the rows being read on subsequent read-refresh cycles until all rows for each and every column address have been read, scrubbing errors if found, thus providing a scrubbing function that is integrated into the read-refresh operation, rather than being an independent operation. For scrubbing, an atomic read-correct-write operation is scheduled. A variable-priority, variable-timing refresh interval is described. An integrated card self-tester and/or card reciprocal-tester is described. A memory bit-swapping-within-address-range circuit, and a method and apparatus for bit swapping on the fly and testing are described.

Abstract: A process for the continuous production of a mixture of substances or of a reaction mixture that has been formed by reaction of components contained therein. The component streams withdrawn from a storage container (1, 2 or 3) or a distribution network (12) are each conveyed via a controlled system (22, 23, 24, 25) which in each instance comprises a flow-measuring device (8, 9, 10, 11) and a regulating element (34, 35, 36, 37). The flow-rates of the individual components are regulated in quantitatively proportional manner with reference to the flow-rate of a first component. The resulting regulated flow-rates are introduced into a receiving container, either directly or after individual flow-rates have been completely or partially conducted together. The process and the device are especially suitable for the on-site production of mixtures of substances that cannot be transported or that can only be transported in elaborate manner, such as relatively highly concentrated solutions of peroxycarboxylic acid.
