Similarly, the second transistor (242) acts as a clamping diode to prevent positive voltage overshoots of the high level output voltage provided by the first transistor (228). The clamping remains effective when the bus driver circuit (200) is disabled.

Abstract: A decoder for descrambling encoded satellite transmissions comprises an internal security module and a replaceable security module. The program signal is scrambled with a key (704) and then the key itself is twice-encrypted (710,715) and multiplexed (732) with the scrambled program signal. The decoder (706) performs a first key decryption using the second secret serial number (SSN₂) stored within the decoder (712). The partially decrypted key is then further decrypted by the replaceable security module (714) using the first secret serial number (SSN₁) stored within the replaceable security module (717). The decoder then descrambles (708) the program using the twice-decrypted key. The replaceable security module (714) can be replaced, allowing the security system to be upgraded or changed following a system breach. Either security module may become the active security module to finally decrypt the seed, selectable by a signal transmitted from the encoder (721). 
     Also disclosed is a method for transmitting (1284) the encrypted keys and secret serial numbers to a plurality of broadcasters (1286) who may in turn multiplex this signal with their own program signals so that any given channel received by a subscriber (1289) contains the key and secret serial numbers. Additionally, the decoder (1306,1390) may be upgradeable to accept both analog and digital video signals without significant redundant circuitry.

Abstract: A high-order sigma-delta modulator comprises at least two integrator stages (H1-Hn). The first one, two or three integrator stages (H1-H3) of the high-order modulator form a low-order modulator which is stable at all input signal values. The arrangement comprises a means (31) for resetting those integrator stages (H3-Hn) subsequent to the low-order modulator when the stable operation input signal range of the high-order modulator is exceeded. Thus, in the stable operation range, the modulator operates as a high-order modulator, whereas outside this range, the modulator operates as a low-order modulator and so operates stably at all input signal amplitudes.

Abstract: A medical imaging system has a source of X-rays and a detector which produces an electrical signal in response to X-rays from said source. A circuit amplifies the electrical signal by a gain factor that varies in response to a number received from a gain control circuit. A converter transforms an analog output signal from the amplifier into digital data. An error compensation circuit stores an offset correction value and a gain correction value for each value of the number from the gain control circuit. A pair of correction values is selected based on the gain of the amplifier for a given item of digital data. The selected offset correction value is summed with the item of digital data and the result is multiplied by the selected gain correction value. A circuit is provided to numerically integrate the corrected data.

Abstract: A method of process control using linear programming models to implement the control of one or more controlled variables to maintain a desired target value over a given time horizon. The controlled variables are controlled by a process controller which adjusts manipulated variables in real time. The method uses two linear programming models with the second model computed from the solution of the first in which the absolute value of the deviation for each controlled variable from its target value over a specified time horizon is computed. This permits the controlled variables to be adjusted with the changes in the manipulated variables held to a minimum over the time horizon under control.

Abstract: The invention relates to a solar water heater with integrated storage, which can be filled isothermally with water at a freely selectable temperature and goes into the mode of operation of a thermosiphon installation when the tank is full. Collector and storage tank are accommodated in a compact manner in a flat unit and can be constructed in a light and economical manner as a result of the pressureless operation. Two principles of solar water heating take effect in combination: primarily cold water is heated directly to the desired end temperature during one flowthrough of the absorber, resulting in good collector efficiencies and rapid availability. If the storage tank is full, a thermosiphon circuit starts automatically, which further heats the storage tank content and/or compensates its heat losses. <IMAGE>
