Abstract: A magnetic pump drive comprises an isolating shell which is structured in the form of a stepped cylinder having at least one step for creating at least two cylindrical sections of different diameters. The efficiency of the power transmission of a driver carrying permanent magnets through the isolating shell onto a rotor also carrying permanent magnets is maintained in comparison with the efficiency of known devices, but the strength and form stability of the isolating shell is drastically improved. The strength against high system pressures is based on the steps which may comprise slipped-over rings or comprise integral reinforcement rings which act like barrel hoops.

Abstract: Methods and apparatus are disclosed for transferring data to and from a first bus, to which a first set of high performance devices, including at least one central processing unit ("CPU") is attached, and a second bus, to which a second set of relatively lower performance devices is attached. The aforesaid transfer function is accomplished in a manner that facilitates communication between the first and second set of devices from the comparatively lower performance of the second set of devices. According to the preferred embodiment, an input/output controller i.e., ("IOC") is disclosed that includes a set of address mapped I/O ports. The I/O ports may be used to transfer data between the high performance channel (hereinafter referred to as the "Local Bus") coupled to the CPU in a reduced instruction set computer (RISC) system and a typically lower performance, peripheral bus (hereinafter referred to as a "Remote Bus"). The resulting IOC interface between the Local Bus and a Remote Bus permits a wide performance range of standard peripheral devices to be attached to the RISC system in a manner that does not limit system performance. Additionally, the IOC may be used as part of a data transfer controller ("DTC") having other components, such as direct memory access means, or may be used independently for transferring data between unmatched buses in, for example, RISC and non-RISC systems and data transmission systems generally.

Abstract: Method and circuitry is disclosed for controlling and stabilizing temperature of a resistance heat sealing element used in packaging operations. Temperature of the heat sealing element is measured by monitoring its resistance by means of a current sensing resistor placed in series with the heat sealing element. The resistivity of the heat sealing element is a function of temperature and current measurement, assuming substantially constant applied voltage, is an accurate measure of sealing element temperature. The circuitry reduces application of electric power to the sealing element in response to current in the sealing element dropping below a predetermined level. The circuit either continues application of electric power, or increases it, in response to the current being above the predetermined level. Circuitry is also provided for compensating for undesirable line voltage changes to maintain the heating element at a constant temperature. Means is provided for adjusting the predetermined temperature at which power cut off occurs. The circuit and sealing element can be operated in either a continuous manner of in a "one-shot" fashion which has been determined as particularly useful for making seals which bear embossed indicia.

Abstract: A pulse oximetry system is provided in which LEDs (12, 14) of two different wavelengths illuminate tissue containing arterial blood flow. A photodiode (16) receives light from the LEDs and produces electrical signals (IR(t) RED(t)) containing pulsatile components. The components of the two wavelengths are separated and the pulsatile waveforms are monitored until signal peaks (IRmax) are detected at the end of diastole. The waveforms are then integrated over the systolic interval, and the integrals are combined with the signal peak values to determine an index value. The index value is used to select a value representative of oxygen saturation from a look-up table (36).

Abstract: A method of determining the reception time of a signal containing a predetermined code, e.g. a Barker code. The code may be present at the start of a telegram to be received by a mobile radio from a base station. The signal is correlated with a corresponding code stored in memory. The correlation is carried out at different offsets in time. This gives a correlation curve (figure 2). The apex represents peak correlation. The timing of optimum correlation is determined by extrapolating the sides to the apex. The invention also provides a zero crossing detector for timing zero crossing events whereby sufficiently accurate timing of receipt of the code is possible to enable meaningful correlation.

Abstract: The invention relates to a control system with which the rope (3), drawn off from a cable drum (4) by a ramming weight (5), can be braked essentially without shocks within a predetermined overrun travel while avoiding a slack rope formation and while maintaining the selected drop height during subsequent blows, the winch drum being driven with adjustable torque by a motor (12) via a slip clutch. The torque when lifting over the height of the overrun travel is set to a threshold value which is matched to the weight of the rope and the load suspension device in such a way that the latter, but not the ramming weight (5), is lifted. After the threshold value is reached, the tensile force of the rope activates a measuring device (15) before or during the lifting of the ramming weight, which measuring device (15) measures the sectional length up to the desired drop height. When the threshold value is reached, the clutch is switched from the lower torque of the overrun travel to the torque for lifting the ramming weight or to the rated torque. The clutch is switched to free running after a rope length corresponding to the drop height is wound onto the winch, and the winch brake is engaged as soon as a rope length corresponding to the drop height has run off the winch drum. <IMAGE>

Furthermore, a current measuring element (8) which informs each microcomputer (1, 2) of the presence and the value of the load current for the purpose of evaluation is arranged in the load circuit. <IMAGE>
