Abstract: The circuit described for the electronic control of internal combustion engines essentially comprises an electronic control unit, an electronic program memory, an absolute value angle pick-up, an engine failure detection circuit, a firing sequence circuit and a valve control device. The absolute crankshaft angle in the dynamic and static state is sensed by a gear with a cyclic code mounted on the crankshaft and relayed to the control unit. In addition further operating parameters (control variables) of the internal combustion engine are relayed to the control unit. By means of a control program the control unit determines the necessary control signals on the basis of actual operating parameters for the individual components (inlet valves, outlet valves, injection valves, ignition device). In this way the ignition point and duration, the valve opening and closing times and their relative phase position are optimally matched to the actual engine state. With a run-up program the control unit can start the engine from any initial cylinder position without additional electrical starter.

Abstract: In a data conversion method of converting source data of M bit units to be recorded on a recording medium into conversion data of N (> M) bit units, n, which is a number of inter-symbol interferences permitted in a transmission path, continuous codes in the codes of the conversion data are weighted with a weighting distribution decreasing linearly from a distribution centre, the weighted n continuous codes are sequentially added to form the intermediate series, and then such conversion data that the sum of absolute values of differences of codes between the intermediate series (i.e., the code length) is more than a predetermined multiple of a reference value of the weighting coefficient is selected as a modulation code, whereby the pattern length between the code patterns can be made larger to thereby improve the recording density remarkably with using the present recording medium and recording and/or reproducing apparatus. Further, the pattern of the reproduced signal corresponding to the data to be detected is compared with a code pattern group corresponding to each conversion data to select a similar pattern so that the conversion data recorded at a remarkably high recording density can be positively detected while using the present recording medium and recording and/or reproducing apparatus.

Abstract: An Address Protection Circuit (APC) for cross-checking the integrity of requests to read or write an addressable system memory in a fault-tolerant computer system. In the check mode, the APC checks each address and the source identification code of each memory access request from an address source. The source identification and current bus address are compared to a range of addresses stored in the APC. If the current bus address is within an "authorized" range, access to that range of locations in the memory is allowed to the address source. If a current memory access request is not authorized, the APC asserts an error signal, which may be used to transfer control to a redundant subsystem. The APC contains a content-addressable memory element that can be initialized by the subsystem processor with address ranges and type of access allowed for each source. In the setup mode, the APC is first addressed to switch the APC from its check mode to its setup mode. Thereafter, a single value in the APC tables can be changed by the processor. The APC then automatically reverts to its check mode.

Abstract: A channel assignment system provides channel assignments to make effective use of the available frequency spectrum by assigning one channel at a time until all the channels in the allotted frequency spectrum are used. A pre-allocation step assigns specified channels to certain cells and these assignments are checked against initial input system constraints. Then the remaining channels are assigned one at a time to the cells according to defined system performance constraints and the number of channels required by each cell. Each cell is defined by its logical faces. The traffic load for each logical face is defined according to selected factors which may include call rates, blocking rates, handoff thresholds, access thresholds, call drop rates, etc. Given these factors the number of channels required by each logical face can be derived and input to the channel assignment system. A level of interference is determined for each logical face as caused by every other logical face by a signal matrix computer (410). Factors involved in this determination include geographical terrain, transmitting antenna properties transmission power and the location of individual cells. A signal-to-interference matrix is developed from this information. The individual channels are now assigned (420,440) to the logical faces based on the developed information including the number of channels needed at each logical face, the signal interference matrix and other system constraints (425).

Abstract: The present invention provides an RDS receiver for use with an automobile which receives data concerning radio broadcasting stations incorporated within a network and is capable of, in case the electric field strength of a radio station currently being received has decreased to less than a predetermined level in some way or other, automatically selecting a radio wave broadcast from another radio station having a higher electric field strength in the same network, wherein the RDS receiver, in automatically changing from a radio station currently being received to another radio station broadcasting the same program, extends or shortens a muting time during which the muting operation is executed, by controlling a station detector (SD) waiting time, which is a required period of time until the SD signal becomes high level, in proportion to a difference between the frequency currently being received and that of another radio station. 
     In order to complete the above object, the RDS receiver according to the present invention comprises a controlling means to calculate a difference between the frequency currently being received and that of another radio station, and controls an SD (station detector) waiting time in proportion to the thus figured-out difference therebetween.

Abstract: An adaptive controller for delivering a fractional amount of oxygen to a patient. The controller utilizes an oximeter coupled by a non-invasive sensor to the patient for measuring the blood hemoglobin saturation in the patient. The oximeter generates a plurality of blood saturation output signals over a given period of time which are sequentially representative of the patient's blood hemoglobin saturation. A processing means evaluates a plurality of the oximeter output signals and, based on the evaluation, provides a pseudo blood saturation signal. A feedback control means responsive to the pseudo output signal sets the fractional amount of oxygen to be delivered to the patient. When deviations of the oximeter output signal are excessive, the pseudo output signals cause a gradual increase in the fractional amount of oxygen for the patient. Furthermore, the feedback control means is periodically disconnected, and the response of the patient to random changes in the fractional amount of oxygen delivered to the patient is used to adapt the response characteristics of the feedback control means in a manner tailored to the needs of the patient.

Abstract: In the method according to the invention for generating a signal for driving a chassis control system in motor vehicles, first signals are detected which represent the speed of rotation of at least one wheel. On the basis of these first signals, second signals are determined which represent the average speed of rotation of at least one wheel or at least one axle. In order to drive a chassis control system, third signals are used, the difference between the first signals and the second signals being determined in order to form the said third signals. In this process, the third signals represent the dynamic wheel load on the respective wheel. By means of the method according to the invention, the dynamic wheel load is determined by means of the signals for the speed of rotation of the wheels. These signals for the speed of rotation of the wheels are already present in vehicles with an antiblocking system (ABS) and/or with a drive slip system (ASR). <IMAGE>
