Title: Range scanner motion estimation method and device
Inventor: KASVAND TONIS
IPC: G01B11/24
Filed: 1992-07-30
Abstract: RANGE SCANNER MOTION ESTIMATION METHOD AND DEVICE      Inventor: Tonis KASVAND                       ABSTRACT      A range scanner measures distances to surface elements in a scene. A list or an array of such distance (Z) readings is obtained from a range scanner. When a range scanner is moving, say, it is mounted onto a mobile robot, sequences of distance readings will comprise of the motion of the scanner and the motions of freely moving objects in scene being scanned. Range scanner motion may be estimated from transducers mounted, say, onto the mobile robot. Alternatively, the motion of the range scanner may be estimated from sequences of distance readings (Z) taken, minimally, at two different times t1 (giving Z1) and t2 (giving Z2). The method is characterized by a way of computing the six motion parameters form Z1 and Z2, etc., which represent the motion of the scanner only. The advantages are: The motion transducers are not needed, or if used, their readings can be checked and/or corrected. This enables, for example, a mobile robot with a range scanner to keep track of its motion and plan future moves.

Title: Electrooptical sensor system for marine seismic data acquisition
Inventor: GATEMAN JAN
IPC: G01V1/38
Filed: 1991-02-22
Abstract: The present invention concerns a system for detecting and acquiring marine seismic data generated by conventional seismic signal sources. The system consists of an electrooptic sensor (1) and a signal processor (10). The electrooptic sensor emits light energy which when reflected from the scanned sea surface (4) is frequency shifted by movements in the water surface, created due to incoming seismic pressure waves (3). The reflected light signal is received separately from each surface part (12) by the electrooptic sensor, processed in the signal processor and recorded in a data recorder (11). This system entails that the activity of mapping underground formations at sea can be done without using seismic streamer cables.

Title: High frequency producing device and oscillator comprising differential amplifiers
Inventor: BLADH MATS A R
IPC: H03K5/00
Filed: 1992-09-09
Abstract: ABSTRACT            According to the invention a circuit is provided for an oscillator circuit comprising a differential amplifier such as an ECL line receiver (ECL1) which directly, in one step outputs a symmetrical square wave signal. This is obtained by means of a symmetrical connection of the bias voltage (VBB) to the input terminals of the ECL-line receiver (ECL1) through two substantially equally large resistors (R1,R2). A feedback loop comprises, as is conventional, a crystal (Xt) and a trimming capacitor or a capacitor which may be controlled in some other way (D1 together with Cf) as well as a resistor (R3). The capacitor will together with the resistor form a low-pass filter for the control of the oscillating condition of the circuit. Further an overtone synthesizer is provided adapted to generate even multiples of the frequency of an input signal and it comprises an ECL line receiver (ECL2), the positive and negative output terminals of which are directly connected to each other. With appropriate voltage levels of the input signal an output signal is obtained containing spikes or dips which are repeated at a frequency corresponding to the double frequency of the input signal. From this signal harmonic components may be obtained having frequencies corresponding to even multiples of the input signal frequency. For the filtering of a multiple chosen a LC-network may be used and for the shaping of the signal another ECL line receiver (ECL3) is used, on the output terminals of which a square wave having ECL-levels is obtained. When the overtone synthesizer is built into the same unit as the oscillator above a very simple circuit is obtained which is not costly, is easily used in other applications, has a high output frequency and has an output signal of well defined levels.

Title: Self-gettering catalysts
Inventor: HEYWOOD ALAN E
IPC: B01J35/00
Filed: 1991-07-30
Abstract: A catalyst unit (16), in which a quantity of a relatively expensive material such as platinum is replaced by a greater quantity of a relatively inexpensive material such as palladium. Thus, material cost saved by "tailoring" a pack is used to pay for a large quantity of a cheaper material. Although the cheaper material is generally less intrinsically efficient than the expensive material, a sufficient additional amount of the cheaper material can be used to more than compensate for this lack of efficiency. Thus, a catalytic pack of high catalytic efficiency, low material cost, low metal loss and long run duration can be produced.

Title: Pyrometer temperature measurement of plural wafers stacked in a processing chamber
Inventor: ISHIKAWA HIROICHI
IPC: H01L21/00
Filed: 1992-05-14
Abstract: An apparatus for batch processing flat articles such as semiconductor wafers (14) in a sealed chamber (12) and a method of measuring and controlling the temperature of articles stacked in parallel in the chamber. A pyrometer (53) is positioned outside of the chamber and directed, either directly or with mirrors, through a window (51) in the chamber wall (11) so that only energy from wafers removed from the ends of the stack is received by the pyrometer. The pyrometer is inclined at an angle so that substantially all energy from the opposite side of the stack and reflected through spaces between facing parallel pairs of wafer surfaces will have been reflected a large number of times by the wafers before entering the pyrometer. Thus, regardless of the emissivity or transmissivity of the wafers, the energy incident upon the pyrometer will approach that emitted by a black body of the same temperature as the wafers, and the temperature read by the pyrometer will be independent of the emissivity or transmissivity of the wafers.
