Title: Method and device for determining separation and relative speed of a distant object
Inventor: ROHLING HERMANN
IPC: G01S13/931
Filed: 2001-10-10
Abstract: The determination of separation (R) and relative speed (v) of at least one object which is distant from an observation point can be achieved by sending electromagnetic signals from the observation point, with a frequency shift over a modulation range (f~Sweep), in the form of signal segments (A, B) during a measuring interval, with a frequency separation (f~Shift) from each other which are transmitted alternately, the echo signals from which are detected after reflecting from the object. The phase difference (.DELTA..phi.) of the echo signals arising from each signal segment (A, B) is detected. Said determination occurs with short reaction time and high precision whereby the signal segments (A, B) are transmitted with a stepwise shift each time by a frequency step (f~Incr) over the modulation range (f~Sweep) and at least one sampled value for determination of the phase difference ((.DELTA..phi.) for each signal segment is taken.

Abstract: A computer system and object-oriented method and class for use with the computer system to convert data in Unicode format back and forth to data having a fixed-leng th format, such as EBCDIC, and to allow editing of the data and return the edited data back to its original format without loss of bytes. Conversely, the method, class, and computer system al so allow the downloading of data in a fixed-length format into a Unicode environment, the fixed-length format is converted into an editable form and then reconverted back into the fixed- length format without loss of bytes. The method accommodates UTF-8, UTF-16, and UTF-32. Once the fixed-length of the data has been determined, a byte array is created and an attribute indicating whether a character is a single byte character or a double-byte character is assigned to each by te in the array. The array and subset arrays representative of fixed-length fields within the fixed- length statements may then be truncated, and/or repaired at either or both the beginning and the end, and/or right- or left- aligned to realize a version of the data that can be displayed and edited without lo ss of bytes. Once edited, using the assigned attributes, the byte array can be converted to code havin g the fixed-length format or can be translated back to Unicode.
