摘要:
In one embodiment, a method of tracking multiple objects with a probabilistic hypothesis density filter is provided. The method includes obtaining measurements corresponding to a first object with at least one sensor, the at least one sensor providing one or more first track IDs for the measurements. A Tk+1 first predicted intensity is generated for the first object based on a Tk first track intensity. A Tk+1 measurement from a first sensor of the at least one sensors is obtained, the first sensor providing a second track ID for the Tk+1 measurement. The second track ID is compared to the one or more first track IDs, and the Tk+1 first predicted intensity is selectively updated with the Tk+1 measurement based on whether the second track ID matches any of the one or more first track IDs to generate a Tk+1 first measurement-to-track intensity for the first object.

The invention relates to a position transmitter with a position code and an optical sensor element for detecting at least one part of the position code. The sensor element has a row of photosensitive detection regions, which convert incident photons into electric charges, and a readout structure for outputting an electric data signal corresponding to the stored electric charges. The sensor element has an analog memory unit structure with a number of N>1 rows of photo-insensitive analog memory cells in order to temporarily store the electric charges and an electric switching structure, by means of which a charge transfer can be carried out between the detection regions and the memory cells, between the memory cells amongst one another, and between the memory cells and the readout row.

A process chart recorder for the on-line recording of process measurement data that has a dot-printing head. In order to develop a chart recorder arrangement having a dot-printing head of the generic type to the extent that the overall printing operation can be effected more easily using mechanically or electromechanically simple means, the printing actuation of the dot-printing head and the actuation of the pen wheel is effected through a common stepping motor. The stepping motor is provided with mechanical means through which the stepping motor is coupled to the pen wheel in a manner causing rotation in one direction and blocking rotation in the opposite direction, with the result that, in one direction of rotation of the stepping motor, only the pen wheel can be actuated and, in the other direction of rotation, the entire dot-printing head can be lowered for printing.

A multi-channel recording device for recording the time profiles of a plurality of measurement signals which can be connected to the device. The device has first and second groups of optical indicators on the front of the device and scale strips corresponding to the physical variables to be measured. There are n indicators in the first group, m indicators in the second group and scale strips where n is greater than m. The device assigns one and only one of the m indicators to each of the n indicators.

A chart recorder is disclosed which has n (n=1, 2, 3, . . . ) measuring channels, one for each of n measurement signals to be recorded, a printing device (5) which produces n isochromatic dot sequences (8) as curves each associated with one of the n measurement signals on a recording medium (4) moving past it, and 1 to n writing devices (9) for 1 to n different colors which overwrite or underwrite one or more of the dot sequences (8), at least in sections, with a continuous line (10) of another one of the n colors which follows the measurement signal of the respective channel, or a color-printing device (15) for 1 to n different colors which marks selected dots of each curve with dots (18) of another one of the n colors. Thus, the n dot sequences (8) are clearly distinguishable one from the other, particularly at curve intersections, and additional functions, such as alarm markings, can be realized.

Apparatus for detecting and displaying on a polygraph record chart any change in either the sensitivity or balance control of each polygraph electronic module. The apparatus includes a detector in the form of a differentiator for detecting a change in voltage on the wiper of the sensitivity or balance potentiometer that produces a signal indicative of the voltage change, and a display operatively connected to the detector for displaying a signal indicative of the adjustment of the potentiometer. The record chart display includes circuitry having a monostable multivibrator configured as a non-retriggerable one shot device responsive to the voltage change signal from the detector to provide a single pulse driving signal to a pen driving motor. The circuitry also includes a rectifier circuit in the form of comparators responsive to the voltage change signal for producing a positive trigger signal to the one shot device. The pulse amplitude and width of the waveform on the record chart display may be varied to indicate which polygraph channel and potentiometer was adjusted.

In a multi-position graphics plotter pen carousel system employing a pen capping mechanism therein at each pen position for capping and uncapping pens held by the carousel, an improvement for allowing the sensing of pen presence at the pen positions and the indexing of the carousel with a single sensor. Each pen capping mechanism is adapted to assume a first position with a pen in the pen position and assume a second position with no pen in the pen position. A plurality of first sensible attributes are associated with respective ones of the pen capping mechanisms for exhibiting a first characteristic when a pen is contained at the associated pen position and for exhibiting a second characteristic when no pen is contained at the pen position. A plurality of second sensible attributes are associated with respective ones of the pen positions for constantly exhibiting the first characteristic. There is a single sensor for sensing the first and second characteristics and for developing a sensible signal at an output thereof indicating whether the first or second characteristic is presently being sensed. The plotter logic is adapted to sense the first sensible attributes and step the carousel between respective ones of the first sensible attributes when sensing pen presence with the sensor and to sense the second sensible attributes and for step the carousel between respective ones of the second sensible attributes when indexing the carousel with the sensing attributes whereby the sensible signal at the output of the sensor indicating the first characteristic indicates the presence of a pen at a pen position of the carousel when sensing the first sensible attributes and indicates the passage of a pen position when sensing the second sensible attributes to count pen positions to index the carousel.

In a recorder having a record head which discharges liquid to record dots and which has a discharge energy generating element arranged on a substrate, a liquid discharge port arranged for the discharge energy generating element and a liquid path for supplying the liquid to the liquid discharge path, non-discharge of the liquid in the recorder is prevented by energizing the discharge energy generating element in a non-discharge condition when the recorder is powered on and/or when a predetermined waiting time has elapsed.

A pen changer for use in an X-Y plotter which plots on a paper. The pen changer includes a frame and a shaft supported thereon. The carriage is supported on the shaft and guided thereby. The carriage includes a plurality of recording pens. The pen changer includes a frame and a shaft supported thereon. The carriage is supported on the shaft and guided thereby. The carriage includes a plurality of recording pens arranged along the axial direction of the shaft. The carriage moves essentially perpendicular to the paper. A hammer is axially movable on the shaft in response to movement of the carriage. A changing mechanism positions the hammer with respect to a selected one of the plurality of recording pens so the hammer can select the selected recording pen to plot on the paper.
