IPC: G01S7/52
Filed: 1991-04-18
Abstract: Calculation of the two-dimensional velocity vector (17) of liquid flowing through a region (3, 16) which is imaged in a B-mode ultrasonic echoscopy display involves dividing the region into a number of small, preferably rectangular, cells (4). One of the cells is scanned rapidly, at least twice, by a beam of ultrasonic energy which is transmitted sequentially along a number of lines of sight (2) which intersect the cell. An image of the cell is formed from the signals reflected from scatterers within the liquid in the cell during each scan of the cell. The two-dimensional brightness functions, S(x,y), of each image of the cell form of a data set S(x,y,t) after the repeated scanning. The data set S(x,y,t) is integrated separately with respect to x and y by projection onto the (x,t) and (y,t) planes. Using the projected functions of S(x,y,t), the average velocity of the scatterers in the cell (and hence of the liquid flowing through the cell) is obtained in the x-direction and in the y-direction. From these two average velocities, the magnitude and direction of the two-dimensional velocity vector is obtained, and displayed on the echogram. The scanning, imaging and computational procedures are then repeated for another of the cells.

Title: Passive ranging technique for infrared search and track (irst) systems
Inventor: GREGORIS DENNIS J
IPC: G01C3/08
Filed: 1993-06-21
Abstract: ABSTRACT OF THE DISCLOSURE         In an IRST system, a determination of the range and type of a detected target may be made as follows.  Atmospheric transmittance and background spectral radiance is estimated from available meteorological data and then, at each of consecutive scans, the contrast irradiance in the direction of a target is measured as well as the azimuth and elevation of said target. A target type is selected from a library of target types storing signatures of the target types considering the measured contrast irradiance as well as the measure of the contrast irradiance at the  previous  scan  (if any).    The  range of  the target  is calculated considering the selected target type, the estimated atmospheric parameters and the measured contrast irradiance. Where the target has other than a radially inbound trajectory the trajectory of the target is  estimated and the  target type selected from the library, considering the estimated trajectory. The range of the target is estimated considering the selected target type, the angular movement of the target, and the range estimate for the target made during the last scan.  Given two range estimates, the estimates are combined.

Abstract: A process for the manufacture of billets and blooms from continuously cast steel, allowing such long products to be directly conveyed to a finishing rolling mill in a plant supplying high quality steel and/or excellent quality steel. Said process is comprising a liquid core distortion stage, concerning the casting cross section and causing the reduction of the same cross section, the perimeter remaining unchanged (equal). Said distortion occurs in the zone comprised between the point (S), last point on the casting axis (X-X) where superheated liquid is still present, and the point (L) where the casting is completely solidified (end of the metallurgical length). Preferably, said distortion is carried out between the points respectively corresponding to 10 % and 80 % of the concentration of solid grains in the fluid mass. An apparatus is described too, essentially comprising means for bringing at least one of the sectors forming the roller train (along the casting route) near the opposite one, in at least one plane containing the casting axis (X-X), in correspondence of said distortion zone.

Abstract: An energy absorbing device for use alongside a roadway to decelerate an impacting vehicle includes first and second elements.  The first element extends in an axial direction and includes a threaded portion that defines a multitude of projecting ridges.  The second element is movable relative to the first element in the axial direction, and the first and second elements are sized to create an interference fit such that relative axial movement of the second element applies a shear load to the first element to progressively deform successive ones of the projecting elements.  This progressive deformation of the projecting elements retards relative axial movement between the first and second elements.

Title: Monitoring System for Batteries During Charge and Discharge
Inventor: NOR JIRI K
IPC: G01R31/36
Filed: 1992-10-15
Abstract: A monitoring circuit is provided to monitor batteries white they are being charged or discharged, where the batteries comprise a series of modules or cells that are connected in series. A terminal is placed between each adjacent pair of modules and at each end of the battery, so that voltage across each module may be measured at the pair of terminals that define the module. Several different determinations of module voltage may be made during charge and/or discharge of the battery including the resistance free voltage of the module, and the module voltage while current is flowing through the battery. Generally, same or all of the modules are tested periodically, where the interruption interval for internal resistance free voltage determination may be in the order of 2 to 3 ms, and the testing frequency for the battery may be in the order of 0.5 to 25 Hz. Alarms may be triggered in the event of module voltages being sensed that are outside of predetermined limits, meaning that the charging and/or discharging characteristics of any of the modules have changed and are significantly different than those of the other modules. By such alarm indications, the module may be changed before serious damage occurs to the battery, either by overcharging or severely discharging the battery.
