Patent EP-0194714-A2 (EP)
Inventor: HEETSCH HERBERT
IPC: G01S11/08
Filed: 1986-03-03
Abstract: To determine the distance between two points by the one-way method of measurement, oscillators operating at exactly the same frequency are necessary at the two points. If one point is, for example, a weather probe which only contains a crystal oscillator of simple construction, the systematic frequency drift occurring after switching on the oscillator in the weather probe and due essentially to stress aging of the crystal can be compensated for by correcting the frequency of the crystal oscillator in it at the other point, i.e. in the ground station, to an essentially equal extent. This enables small relative frequency errors between the two oscillators to be achieved so that a distance measurement is possible with high accuracy within a limited time. <IMAGE>

Abstract: A heat-sensitive transfer medium comprising a support and at least two heat-transferable ink layers including a first and a second ink layer. The first ink layer has relative adhesions with the second ink layer and the support which are reverse at a higher temperature from those at a lower temperature. When the heat-sensitive transfer medium is superposed with paper, a heat energy is applied, and the transfer medium is separated from the paper; the second ink layer is selectively transferred or both the first and second ink layers are transferred to the paper depending on the length of time from the heat application until the separation of the transfer medium, whereby two color images can be formed by a single transfer medium.

Abstract: The invention in exemplary, differential absorption laser (DIAL) application, entails determining the number density "N" in an atmosphere column of a constituent whose absorbance is indicative of the value of "N", by use of first of the relationship:-     
     to establish an assumed correct value for "N" (a first value for (a OFF - a ON) being obtained from known data) at arbitrarily chosen "OFF" and "ON" frequencies, thereafter using that value of "N" to determine further values of (a OFF - σ ON) at further "OFF" and "ON" frequencies until a value therefor is detained which is constant or near constant, and then, using that value, re-calculating "N" by the further relationship:-2N(a OFF -aON) x Z  =  1.1 >   where Z is the range, and   a OFF and a ON = the absorbance cross-section for one molecule of the constituent in the column at the respective "OFF" and "ON" frequencies. The technique is also employed to effect a range cell determination as such to effect a range intervening column using appropriate further relationships. It may also be used to determine a parameter other than "N".

Abstract: A device for characterizing the formation of a sheet material is described. The device comprises a basis weight sensor for measuring the basis weight of the sheet material as the material passes through the sensor and signal processing circuitry which receives a signal from the basis weight sensor indicative of the measured basis weight and which produces three types of outputs, which outputs characterize: (1) the magnitude of variation in the sheet basis weight; (2) the strength of the weakest portion or portions of the sheet; and (3) the size of the flocs comprising the sheet. The basis weight sensor includes a light pipe which is held against the sheet, as the sheet moves through the sensor, and which directs a small spot of light transmitted through the sheet to a light detecting device. The magnitude of variation in the sheet basis weight is computed to be proportional to the true root-mean-square variation in the basis weight of the sheet.
