Abstract: An optical position encoder system comprising a circuit for removing the electrical bias usually associated with the optical sensor outputs, and for generating a voltage output varying with the encoder position to produce an indication of angular or linear displacement between zero crossings is described. In one portion of the circuit, sensor output signals 180 degrees out of phase are subtracted to automatically cancel the bias. In another portion of the circuit, signals 90 degrees out of phase are used to generate a voltage, the amplitude of which is a function of the grid position between grid zero crossings. To accomplish these results, two or more angularly displaced grids are required.

Abstract: An electrostatic emission lens arrangement for producing a microparticle ge of a surface by means of charged particles emitted from such surface and accelerated to a predetermined final energy level. Such arrangement includes two apertured diaphragms arranged in spaced relationship to each other and to the emitting surface, and a voltage biasing source for producing a potential difference between the surface and the adjacent first apertured diaphragm electrode, and a potential difference between the first apertured diaphragm electrode and the second apertured diaphragm electrode. According to the invention the spacing distance between the emitting surface and first apertured diaphragm electrode and the spacing distance between the two apertured diaphragm electrodes and, the relationship between the potentials of the surface and of the electrodes are so dimensioned that the charged particles are accelerated between the emitting surface and the first apertured diaphragm electrodes to a multiple of the desired final energy level, and that the particles are retarded to the desired final energy level in passing between the two apertured diaphragm electrodes.

Abstract: Intrusion detector of the type in which the presence of an intruder is detected by infrared heat energy emitted by his body. An alarm signal is delivered when the level of radiation detected rises from the ambient level to a threshold level. A temperature responsive circuit adjusts the threshold level and so that the system has a relatively uniform detection range or sensitivity notwithstanding changes in the ambient temperature in the protected area.

Abstract: The quadrupole mass spectrometer has four conventional rod-shaped poles symmetrically located about the ion injection axis. Opposite pairs of rods are interconnected and connected to an rf voltage source. A shield having a circular aperture is located at the output end of the rods to assure the stoppage of low mass particles. In addition, a stopping element also preferably circular is located on the axis at the output to assure the stoppage of heavy particles. A pair of grids incorporating the stopping element, are sequentially located at the output, normal to the axis, the first is connected to a dc voltage source to accelerate the remaining particles through the fringing field of the quadrupole and the second is connected to a dc voltage source to subsequently decelerate the particles.
