Title: Determining quality of heart function signals from electrocardiograph machines
Inventor: WANG JYH-YUN J
IPC: A61B5/366
Filed: 1999-01-21
Abstract: The method of determining heart signal quality assesses the difference between an EKG signal (600) and each previous signal received to generate a ranking system (628) of the effective quality of the signal. The method works by taking the inputted EKG data (600) is sent to filters and detection equipment (602, 604, 606) and the central point of the waveform is calculated for comparison of waveforms (608), the waveforms are then stored (612, 614) for comparison with each further waveform (616) to generate histogram details on the differences between each signal (622, 624). The final stage of the process uses the histogram data to rank the signal quality (626, 628). An Independent claim is included for the system of characterizing quality of heart function signals.

Inventor: DIRKS ROLF
IPC: H01H3/30
Filed: 1999-06-04
Abstract: The invention relates to a snap-action mechanism for electrical switchgear with a drive shaft and an actuation disk which is non-rotatably linked with said drive shaft and actuates a moving spring. The snap-action mechanism further comprises a transfer element (8) that is rotatably received by the drive shaft and that is hinged at the moving spring and acts upon the switch shaft via a connecting rod (9). According to the invention, the snap-action mechanism is designed in such a manner that the switch-off force required for overcoming the adhesive forces for switching off the switchgear is reliably produced and transmitted. To this end, a pressure spring (18) is arranged between the transmission element (8) and the connecting rod (9) and is mounted on one of these elements of the snap-action mechanism. Said pressure spring interacts with the respective other element of the snap-action mechanism once the dead center position (T) has been overcome.

Title: Receiving digital radio signals over radio channels involves deriving digital filter coefficients using reference signal, deriving channel transfer function for useful signal using filter
Inventor: KUSMANN HOLGER
IPC: H04B7/005
Filed: 1999-06-22
Abstract: The method involves determining the transfer function of the radio channel from received reference signals at the time of reception and at the frequency with which a reference signal is transmitted. Coefficients of a digital filter are derived from the speed of the receiver, the transfer function and the selected carrier frequency. The transfer function of the radio channel for the time of reception and the frequency of the useful data signal is determined using the digital filter and used to correct distortion of the useful signal. An Independent claim is also included for a receiver for receiving digital radio signals over radio channels.

Title: Drive unit speed e.g. revs control method, esp. for combustion engine, involves adjusting magnitude of proportional parameter of controller during start phase of combustion engine
Inventor: MEZGER WERNER
IPC: F02D41/06
Filed: 1999-08-21
Abstract: Control of the starting phase of combustion engines, requires at least one parameter being selected during this phase in order to dynamically and effectively reduce any revs overshoots, the selection of the parameter preferably being adjusted to the shape of the revs overshoots so as to optimize their influence, the start phase ending preferably when the revs initially fail to achieve a given revs rate after the overshoots fail to reach a predetermined revs value. During the start phase of the combustion engine the magnitude of this parameter (P) of the controller (16) is changed, so that a first value of the parameter is specified for the start phase to the end of the first revs overshoot after start-up, and then switch-over to normal operation takes place.

Abstract: The invention relates to a method for producing alkyl-substituted butenols of the general formula (I): R<1>-CH2-CH=CR<2>-CH2OH, wherein R<1> represents a saturated or olefinically unsaturated alkyl or cycloalkyl group with 4 to 16 carbon atoms that can be optionally substituted by an alkyl, cycloalkyl, aryl or alkaryl group   with the proviso that said substituent has a maximum of 12 carbon atoms and R<2> represents hydrogen or an alkyl group with 1 to 6 carbon atoms. The inventive butenols can be obtained in high yields and high purity by reacting the aldehydes of formula (II) R<1>-CH2-CHO, wherein R<1> has the same meaning as in formula (I), with the corresponding lower aldehydes and then reducing the unsaturated aldehydes obtained if (i) the aldol condensation is carried out in an inert organic solvent and (ii) the unsaturated aldehydes are reduced in the presence of optionally calcined copper-zinc. The reduction in step (ii) is carried out in a continuous and isothermal process and at temperatures ranging from 45 - 60  DEG C and at a hydrogen pressure in the range of from 1 to 300 bar.
