Patent SE-8404029-D0 (SE)
Inventor: STEINLE B
IPC: H03H17/04
Filed: 1984-08-08
Abstract: The digital part of the bandpass filter consists of the cascade circuit of several part-filters, all of which or a majority of which are second-order IIR filters (7, 8, 10), and contain an FIR filter (10) in one variant, and of an envelope detector (9). At least two of the IIR filters (7, 8) together form a detuning filter. The frequency ranges which are not, or not adequately, filtered out by the detuning filter are filtered out in two variants with the additional IIR and FIR filters. In addition, there is an analog prefilter which filters out the frequency range not yet filtered, nevertheless, and suppresses the mains frequency and strong harmonics of it to such an extent that an inexpensive analog/digital converter is adequate for the digitisation.

Abstract: A variable ratio lever arm mechanism typically for use with an overhead valve type internal combustion engine incorporates the concept of shifting the fulcrum pivot point about which a generally linear, elongate lever arm pivots relative to its ends. In its application for use with internal combustion engines, the lever arm as described, otherwise known as a rocker arm, is retained in functional position relative to the valve stem and pushrod, or point of contact of a camshaft acting on the rocker arm. The rocker arm incorporates an essentially elongate through aperture through which the fulcrum rod is functionally positioned, so that the rocker arm may pivot about the fulcrum rod. The fulcrum rod is laterally translatable within the rocker arm elongate aperture in a manner to permit changing of the ratio of the moment arms of each end of the rocker arm relative to the fulcrum rod pivot point. Therefore, translating or otherwise relocating the location of pivot changes the relative arc length of travel of each of the rocker arm ends. In this manner, the amount of valve opening can be altered and controlled for any given constant amount of pushrod reciprocal movement or camshaft action. The laterally shiftable fulcrum rod is retained in functional position within elongate through apertures formed in stationary shaft supports which are mounted directly to the head of the internal combustion engine. The geometric design of these through apertures within the shaft supports dictates the lateral motion of the fulcrum rod in order to shift the pivot point of the rocker arms about the fulcrum rod to effect the desired change in moment arm ratios.

Abstract: A control device for controlling the heating capacity of the heating element of a cooking or heating plate, on which a cooking vessel, roasting vessel, or the like, can be placed and heated. The temperature on or in the cooking vessel is determined by means of a temperature sensor, conveyed to a logic circuit, and used in this for the control of the heating element by means of an output stage in dependence on the actual temperature determined and/or the temperature increase in the heating phase. In order for control of the heating output of the heating element to also be performed during a roasting process with a roasting pan placed on the cooking or heating plate, a program selection switch provided to select between various cooking processes, such as rapid simmering, steaming, warming and the like has a coordinated switching position for each and for a roasting process has an additional switching position. The heating output is controlled during the heating phase by means of preset programs of the logic circuit by switching the heating element on and off by means of the output stage in dependence on the actual temperature detected by means of the temperature sensor and/or the temperature increase detected from the temperature curve.

Each finger includes a demodulator (402) for demodulating a ray of a multipath signal and a time tracking circuit (404) for controlling the time position of the finger in accordance with time position of the ray.
