Abstract: A parabolic voltage generating circuit includes an arrangement (IC1) for generating a sawtooth vertical deflection current (i V ) that flows in a vertical deflection winding (L V ), in a DC blocking capacitor (C V ) and in a deflection current sampling resistor (R S ). An emitter electrode of a transistor (Q3) is coupled between the deflection winding and the capacitor. A base electrode of the transistor is coupled between the capacitor and the resistance. A collector current (i c ) of the transistor varies in a vertical rate parabolic manner and has a DC average value that is determined by a DC average value of a voltage that is developed in the capacitor. The collector current is applied to an East-West raster distortion correction circuit for modulating an amplitude of a horizontal deflection current.

Abstract: The invention relates to a circuit for receiving information carried by a two-wire power line and having a frequency which is orders of magnitude higher than the frequency of the low-frequency AC voltage on the power line. The AC voltage on the power line, which interferes with information transmission, is eliminated by coupling the evaluation circuit via a high-resistance resistor bridge into which either a compensation voltage of the same frequency but in antiphase is injected or which bridge is changed in its balance in a frequency-dependent manner by a capacitor. <IMAGE>

Abstract: C-, T- and S-switches have a connector or reed (216,220) in each conducting path. The connector or reed contains a support (230) for a permanent magnet (224, 228). All of the magnets (224, 228) of the connectors (216, 220) have the same polarity. The connectors, supports (230) and permanent reed magnets in the supports are contained within an RF cavity housing (204), which is completely sealed from an actuator (208). The actuator has a circular shape and contains permanent magnets (236, 238) that correspond in their configuration to the reed magnets of the housing. At least two magnets of the actuator have different polarities. The actuator can be rotated by a motor (210) to two or more positions. In one position, one or more of the reed magnets are attracted and one or more of the reed magnets are attracted and one or more of the reed magnets are repelled. The switch is designed so that when a reed magnet is attracted, the conducting path in which the connector is located is interrupted and when a reed magnet is repelled, the conducting path is connected. Previous switches are more expensive to manufacture and more complex, thereby increasing the likelihood of premature failure. Previous switches do not have a housing that is completely sealed from an actuator.

Abstract: Image signal demodulation apparatus for demodulating an FM image signal having a carrier, an upper sideband and first and second lower sidebands, of which a modulating signal frequency is comparably close to a frequency of the carrier. The apparatus comprises an equalizer (3) for equalizing a group delay characteristics of the FM image signal at around the carrier frequency, a moire reduction circuit (7) for delaying, with respect to the carrier, respective aliasing components of the first and second lower sidebands by predetermined amounts respectively in response to the output of the equalizer, a limiter (4) for removing amplitude variations of the output of the moire reduction circuit and restoring the upper sideband, a demodulator (5) for demodulating the output of the limiter. The output of the demodulator contains a baseband component having a maximum frequency, and a lowpass filter (6) for passing only the baseband component lower than the maximum frequency. The demodulator together with the moire reduction circuit causes to perform as such that a first moire component generated due to an aliasing caused upon modulation of the FM image signal, becomes opposite in phase relationship to a second moire component generated upon demodulation of the FM image signal, so that the first and second moire components are cancelled out each other.

Abstract: An electro-optical system intended for medical use that measures and analyses an individual's cumulative short-wave and long-wave UV-radiation exposure as detected by sensor 10 of the system attached to the individual. Sensor 10 separately registers sequences of UV-A and UV-B signals which are synchronized in time by clock pulses. After a predetermined interval sensor 10 is connected to an analyzer unit 12 that statistically processes the collected data to derive risk factor and generate predictive information. Such information permits the physician to predict individual-specific levels of ultraviolet (UV) radiation potentially harmful to the skin and help protect the individual from skin cancer and similar diseases with solar radiation causation.

Abstract: A dynamically configurable operating system is achieved by providing a module sub-system which intercepts requests by processes to access a module in the operating system and determines whether the module has been loaded in the kernel memory and linked the other modules located in the kernel memory and installed in the appropriate table. If the module has been into the kernel memory, and installed the module sub-system grants the requesting installed process access to the module and processing continues. If the module has not been loaded into the kernel memory, the module sub-system will retrieve a copy of the module stored and copy it into kernel memory. The module is then linked to the other modules located in the kernel and installed. Once the module is loaded and linked and installed, access is granted to the requesting process and normal processing continues.
