Abstract: The system for three-dimensional rendering of signals has a computer system having acquired, streaming, or previously stored data in its memory representing multiple channels of signals in which each channel has a value which varies over a domain, e.g., time or frequency, and a display coupled to the computer. For each channel, the computer system segments the data of the channel into segments, orders the segments, renders on the display each of the segments, in which each of the rendered segments are aligned in such order along as three-dimensional perspective with gaps between adjacently rendered segments, and lines are rendered extending from each line of each one of the rendered segments to form a three-dimensional plane in the gap to the next successive one of the rendered ordered segments to form a three-dimensional continuous or discontinuous surface characterizing the channel.

Abstract: A system having an acquisition device for acquiring test and measurement data. For each input data signal, the acquisition device has two differential receivers of opposite polarity each having an output coupled to the input of different ones of two pairs of registers, resulting in four registers sampling the input data signal periodically at four different times in accordance with two clocking signals of different phase (phase shifted) 90° to provide a sampling rate four times the rate of the clocking signals. The resulting sample data is stored in memory along with downsampled data. A computer system can request readout of stored sample data and/or downsampled data during or after acquisition of sample data and downsampled data. The acquisition device preferably utilizes an FPGA to provide sampling, storage and readout of stored data. The FPGA may be reconfigurable to provide one of different data acquiring modes selectable by a user.

Abstract: An automotive vehicle includes an engine, a plurality of electrical load subsystems, and at least one controller. During an auto start of the engine, the at least one controller detects a starter disengage condition. In response to detecting the starter disengage condition, the at least one controller periodically determines a value of an operating parameter associated with the vehicle, causes a first subset of the electrical load subsystems to be enabled when the value of the operating parameter falls with a first predefined range of values, and causes a second subset of the electrical load subsystems to be enabled when the value of the operating parameter falls within a second predefined range of values.

Abstract: A vehicle includes an engine and at least one controller. The at least one controller periodically determines an estimated current to be demanded by vehicle electrical loads during an auto stop of the engine, compares the estimated current with a threshold current, and inhibits an auto stop of the engine if the estimated current is greater than the threshold current for a predetermined period of time.
