Abstract: In a thermal imaging system for passive imaging of infra-red rays, a converging imaging cone is incident on a detector 2. To shield the detector from rays outside the imaging cone which would cause noise, a thin plate 10 is provided and, since the detector is cooled but the plate is not and therefore generates infra-red radiation, the plate is formed as a Fresnel reflector to reflect radiation emanating from the detector back onto itself. As compared with the conventional "cold shield" reflector which has a spherical reflecting surface, the use of a plate formed as a Fresnel reflector makes the imaging system thinner in the axial direction in the region of the detector.

Abstract: In a hysteresis comparator for comparing an input Vin1 with another input Vin2, the comparator comprises a pair of first and second transistors (Q1, Q2). The gate of the first transistor (Q1) is supplied with the input Vin1 and the gate of the second transistor (Q2) is supplied with the input Vin2. Their collectors are connected to a power supply. The emitter of the first transistor is connected to a first current source (I₁) and the emitter of the second transistor is connected to a second current source (I₂). The comparator further comprises a circuit (105) for detecting an emitter voltage difference between the first and second transistors and varying at least one of the first and second current sources. Therefore, the hysteresis width can be determined by the collector current ratio of specific transistors, regardless of the absolute values of their collector currents.

Abstract: An elongated valve means (10) is operable between a closed and opened position and is connected to a tubing string (14) for flowing fluid along an isolated flow path from a location downhole in a wellbore (11) to the surface. The valve means includes a main housing (41) within which a mandrel (38) is axially aligned. A packer (17) divides the borehole annulus into an upper and lower annular area. The valve device includes an annular power chamber (62) formed between the mandrel and the main body, and slidably receives a power piston (63) therewithin. The power piston is connected to a medial part of the mandrel. Metered flow from the upper borehole is indirectly effected on the piston face, thereby driving the piston uphole and carrying the mandrel therewith. The lower end of the mandrel has ports (75) formed through a sidewall thereof which are brought into registry with a complementary port (70) formed through the sidewall of the main housing. The housing port is in fluid communication with the lower borehole annulus. Detents (54) formed in the mandrel are engageable by a latch means (53) which positions the mandrel axially as the ports are brought into registry with one another. The latch means is retracted by a piston operated arm (51). Fluid pressure from the upper borehole annulus indirectly actuates the piston operated arm. The movement of the piston actuated arm and the power piston sequentially occur so that the latch means successively engages adjacent detents while successive ones of the mandrel ports are brought into registry with the port of the housing. Accordingly, the valve means is opened to admit fluid thereinto and up to the surface of the ground, whereupon the valve means is then moved to a first closed position, and thereafter again moved into the open position in response to hydrostatic pressure alternately being effected within the upper borehole annulus.

Abstract: A vacuum sputter apparatus capable of performing sputter operations at reduced operating pressure. Magnetic means (14) is supported behind the cathode (6) for producing magnetic flux lines (16) generally parallel to a first, primary surface (8) to be sputtered which is held at a high electrical potential, thus giving rise to a magnetron plasma adjacent the primary surface. The magnetic means confines the plasma to produce a closed loop erosion path on the first surface. A dark space shield (20) extends from the wall (4) of the vacuum chamber toward the first surface, but terminates a distance from the primary surface so as to expose a portion of the second surface (10). The dark space shield is recessed a sufficient distance from the first target surface to minimize the density of the fringing field lines intersecting the dark space shield. In this manner, the plasma generated adjacent the first surface is enriched both by electrons originating from a secondary plasma at the second surface and by electrons reflected back to the first surface moving along the magnetic flux lines. Sputtering action can thus take place efficiently at reduced operating pressure. Reduced operating pressure furthermore provides more uniform film deposition, while eliminating differential segregation of the sputter compound material.

Abstract: Use of paucilamellar liposomal carriers, to the exterior of which hydrophilic molecules are attached, in the transport across the cell membrane of active molecules expressing an affinity for cytoplasmic transporters. These active molecules are chosen from molecules which exhibit an affinity for the receptors or transporters of vitamin A and of steroids, and hence some degree of structural analogy with these compounds, and from molecules which manifest a blockade of melanosome formation by diversion of the enzymatic activity resulting in a hyperactivation of the melanin-degrading enzymes. The invention also relates to dermatological or cosmetic compositions based on these carriers and to their uses in the elimination or attenuation of dyschromia as well as in the treatment of melanoma caused by exposure to sunlight.

Abstract: A ranging system such as a radar system transmits signal pulses toward a diffuse target, such as an atmospheric disturbance. The echoes are processed by quantizing and by doppler filtering to produce a plurality of frequency components representing the radial velocities of various parts of the disturbance, which components are expected to be contaminated by an unknown amount of noise. The noise value is established by squaring the echo signals to produce power-representative signals. The signal samples are ranked according to amplitude, and one or more of the largest-value samples are discarded to reduce the order of the sample set. A Kolmogorov-Smirnov test statistic is generated and compared with a threshold established by the desired confidence level. If the test statistic exceeds the threshold, the order of the sample set is again reduced, and the test statistic again compared with the threshold. The noise level is deemed to be represented by the current reduced-order set when the test statistic does not exceed the threshold.

Abstract: Image processing systems and methods for retrieving digital data stored in a plurality of contiguous data cells on photographic film. An image sensor samples the image data at a plurality of pixel positions in each of the data cells and generates grayscale image data that is processed into a one-dimensional stream of binary pixels. A data sampling system processes the binary pixels by first selecting those binary pixels that correspond to the data cell centers. Then, a digital output signal is constructed from the selected pixels to represent the original data stored on the film. The stream of binary pixels are read in series. In particular, transitions, detected in the stream of binary pixels, are used to periodically estimate the data cell pitch and the transition phase. A plurality of, e.g. N, suggested distances from the current pixel to the next sampling point are located using the transition phases of the most recent N transitions. A preferred sampling phase is determined through a histogram to find a consensus among the N suggested distances. The digital output signal is constructed from those pixels that occur at the preferred sampling phase.
