Patent DE-2800998-A1 (DE)
Inventor: AFFOLTER PETER DR
IPC: H04L27/10
Filed: 1978-01-11
Abstract: A method and a device for remote data transmission are specified which can be used by using a normal telephone connection. The data to be transmitted, for example orders for goods, are stored by means of a keypad (11) via a microprocessor (12) in a memory (13) of a mobile peripheral device (10), which can be carried by a salesman on business trips. An acoustic coupler (20) can be used for connecting this peripheral device to a telephone receiver (31). The data are transmitted error-protected via a receiving station (40) to a data processing system (50). An acknowledgement signal generated by the receiving station acoustically informs the operator (34) whether the transmission was error free or not. To achieve a high transmission rate of, for example, 600 Baud corresponding to about 109 characters/s, an oscillator (16) is used for generating a frequency-shift-keyed signal in the range between 1200 and 1800 Hz. This provides for relatively simple error-protected data transmission at a high transmission rate. <IMAGE>

Title: Circuit for determining time constant of exponential signal - uses delayed version of signal as reference with difference between signal and reference also exponential with same time constant
Inventor: DIETRICH HERBERT
IPC: G04F10/00
Filed: 1979-03-29
Abstract: The time constant or the half-life of an exponentially rising signal is determined by comparing the signal with a delayed version of itself. This difference is also an exponential with the same time constant and known final value of zero. The time constant can therefore be evaluated without needing to know the final value of the original signal. The required computations can be performed using an analogue delay circuit, or they may be performed digitally by taking samples at discrete intervals of time. In either case the output is a time pulse whose length is set by the time taken for the difference between the signal and its delayed version has fallen to a half of its first value.

Title: Regulator for fast charging of batteries - measures incremental voltage change with time to determine fully charged state
Inventor: MOLL REINHARD
IPC: H02J7/00
Filed: 1979-10-03
Abstract: The object of the regulating principle is to prevent the overheating of batteries subjected to fast charging rates at a constant current. The battery terminal voltage is sampled at regular short time intervals, and each sample compared with the preceding one. When the voltage ceases rising, that is when the incremental change is zero or negative, the charger is switched off. The proposed controller is based on the observation that there is a voltage peak with respect to time at the point when the battery is fully charged. If the constant current charging is continued beyond this point the electrolyte heats up rapidly and the cetl voltage falls. With the method thermal sensors are eliminated, and the voltages of several batteries being charged at the same time can be scanned sequentially without additional circuit components.

Title: Hybrid associative memory for sorting stored data - has extra storage unit permitting house-keeping operations
Inventor: WOLF GERHARD
IPC: G11C15/00
Filed: 1980-03-11
Abstract: The memory consists of an associative matrix with numerous fields and a non-associative memory with numerous storage units. The storage units are composed of storage sections corresponding to the associative fields of the matrix such that any one storage section from each storage unit correspond to one another and to the same associative field of the matrix. The contents of each storage section can be transferred to the associated associative field in the matrix. Apart from the storage units for storing general data from files or tables in the base memory at least one additional storage unit is provided to store data and information for simplifying or permitting the utilisation of existing associative surfaces for work processes of the hybrid associative memory. The advantage lies in reducing the number of additional devices needed for monitoring and controlling the degree of filling and for managing lists of parameters and controlling work processes like finding and sorting data.
