Abstract: A compact, cardiac analyzer system (100) provides for monitoring physiological indicators of rapid eye movement (REM) sleep, autonomic fluctuations and ischemia. When any of these "indicators" is detected, a full complement of ECG data is recorded from a subject for subsequent analysis. In the absence of these indicators, only a minimal complement of ECG data is recorded. The system includes a first set of ECG electrode sets (110), from which the data are recorded only during REM sleep, extreme autonomic drive fluctuations, or ischemia, and a second set of ECG electrode sets (112), from which the data are constantly recorded. A set of electromagnetic interference sensors (116) is used to assess environmental noise levels so that corrupted data can be rejected or purified. During REM sleep, autonomic drive fluctuations provide a setting for assessing the variability of fractionated potentials in subjects susceptible to sudden cardiac death. In addition, the muscle atonia characterizing REM sleep provides exceedingly low muscle tremor noise levels. Accordingly, cardiac activity is most thoroughly monitored when fluctuating fractionated potentials are most likely to occur and when tremor noise levels are most favorable for their detection. Data recording is minimized in the absence of the indicators, allowing for up to a 5:1 data reduction during a typical sleep cycle.

Abstract: 2.1 In many applications, structures having different thermal expansions are connected to one another. In order that no stresses arise in such connections, compensation for the thermal expansions is necessary. 2.2 In order to compensate for the thermal expansion of a structure (S), the length of this thermal expansion is initially overcompensated for. This is done by using mechanical components (K12 to K40) with very different thermal coefficients of expansion. The shaping of the mechanical components (K12 to K40) is selected such that their elastic deformation reverses the overcompensation again, to the extent desired for the application. 2.3 Microwave cavity resonators on aluminium structures, integrated microwave circuits on sapphire or ceramic substrates, which are intended to be mounted in aluminium housings, printed circuits, which are intended to be installed in aluminium housings, etc.. <IMAGE>

Abstract: A video signal recording apparatus has an overlap function of gradually switching a video signal read from a memory capable of storing a one-picture portion of an input video signal to another video signal during a first predetermined time period. The apparatus can effectively utilize the overlap function with a simple operation by operating a manual operation member for setting the apparatus to an overlap mode for operating the overlap function when a recording operation is not performed, and thereby confirming an image stored in the memory. When the apparatus is in an interval recording mode in which a recording means periodically operates during every second predetermined time period, the first and second predetermined time periods are determined so that the second predetermined time period is longer than the first predetermined time period when the apparatus is set to the overlap mode. Recording of an imperfect image is thereby prevented.

Abstract: A technique, applicable for use in implementing a print preview function in a color electronic imaging system, that, under a variety of different ambient lighting conditions, will yield a highly acceptable color match between a color image appearing on a CRT monitor and that which will be produced by the system as a printed version of the same image. Specifically, a computer system (120) is employed to scan an image and, through an ambient illumination sensor (27), senses the spectral content of the ambient illumination. The computer displays the scanned image along with various non-image information which can be used to adjust the color of the image. The computer transforms the color of the scanned image and the non-image information such that a resultant display of the image and the non-image information on a color monitor (24) will show the appearance of a print when the print is viewed under the ambient illumination. The transformation of the non-image information includes transforming non-image monitor control signals into a first set of tristimulus values which are, in turn, transformed into printer control signals for an imaginary printer. These printer control signals are then transformed into tristimulus values using the sensed spectral content of the illuminant. This latter set of values are used to produce monitor control signals that are applied to the monitor.

Abstract: Ionization gauge and method of operating same where the gauge may be of the Bayard-Alpert type and include a shield which completely encloses the electron source, the anode, and the collector electrode so that potentials external to the shield do not disturb the electric charge distribution within the shielded volume to thus stabilize the sensity of the gauge. The ionization gauge is further characterized by the following features which may be present either alone or in combination including: (a) the anode is provided with end caps which extend radially inward at least 25 % of the radius of the anode but not more than 75 % of the radius; (b) the ion collector has a diameter of not less than 0.015 in. and not more than 0.080 in.; (c) the ion collector extends at its free end at least through one of the partial end caps of the anode; (d) the electron source is not substantially longer axially than the region within the anode volume in which the electric field is predominantly directed radially inward and where the electron source is located substantially only adjacent to the foregoing region; (e) the anode is provided with a substantially uniformly transparent grid structure in the regions where the electrons enter the anode volume and where they exit the anode volume. A controller circuitry and method for controlling the operation of the ionization gauge has a source of electrons, an anode, and an ion collector electrode, including storing a plurality of calibration data sets for at least collector electrode currents and gauge sensitivities obtained with at least one reference gauge at representative values of known pressures; and calculating the gauge sensitivity corresponding to an unknown pressure in response to at least one of the data sets together with a measured value of the ion collector current. The data sets may also include representative values of the heating powers of the electron source so that the calculated sensitivity may also be compensated for variations in the electron source heating power.

Abstract: Prior art: Alternating transmission of addresses and data on the same bus lines. Technical problem: Transmission of variable-length data blocks. Basic concept: One of the remaining signals present in any case (chip select, CS, read, write) indicates the block length. The first time slot after this signal has been set is intended for an address (start address), all subsequent time slots up until the signal is reset are intended for data. Solution: A counter (FF1, FF2, FF3) counts down the first time slots of a data block and sequentially enables receivers (ZH, ZL) or transmitters for the first (AH) and any further (AL) address bytes, transmitters or receivers (MEM) for data (D1, D2, D3) and lastly a counting clock pulse (ZS) for incrementing the address. The counter is reset at end of block. Advantage: At the beginning of the transmission of a data block, its length does not yet need to be known. <IMAGE>

Abstract: A loading/unloading mechanism for loading and unloading a magnetic head mounted on a magnetic disk drive for recording data in a magnetic recording medium (1). A suspension mechanism (4) exerts a predetermined load on a flying head slider (3) while the disk drive is not operated. A ramp mechanism (5) supports the suspension mechanism (4) and moves the head slider (3) away from the surface of the medium (1). The whole or part of the ramp mechanism (5) is constituted by an oscillation mechanism having a piezoelectric element. The static frictional force acting on the suspension mechanism (4) and ramp mechanism (5) is replaced with a dynamic frictional force to thereby reduce the friction. This saves power at the beginning of a loading operation and facilitates the control over the movement of the head slider (3) caused by a positioner actuator (6).
