摘要： Method and apparatus of storing data in an electrically erasable memory connected to a microprocessor to effectively protect data stored in the memory from being unintentionally overwritten in cases of defective operation of the microprocessor, an overwrite protection system consisting of a write protect flip-flop (1) whose two logical states signify "with write protection" and "without write protction" and also a gate (3) in the write line which is controlled by the write protect flip-flop and in whose logical "with write protection" state, write errors are prevented from being conducted to the individual memory locations, and, finally a mechanical switch element (5) whereby these components are connected in such a manner that the write protect flip-flop (1) can only be brought into the one logical "with write protection" state by the microprocessor, while it can only be brought into the other logical "without write protection" state, if and when the mechanical switch element (5) is actuated. The overwrite protection can apply depending on the embodiment to the entire electronically erasable memory or only to the subareas thereof.

摘要： LCD display boards for electronic balances frequently also comprise, alongside the digits for the digital display of the weighing result, additional fields in which additional information is displayed by means of alphanumeric signs. The invention suggests that the segments of the digits for displaying the weighing result be individually provided with a line and controlled in parallel in order to achieve a very good display quality and that the segments for the display of the alphanumeric signs of the additional field, e.g. a 5.times.7 matrix, be connected in such a manner that they can be serially controlled in order to prevent the number of lines required from becoming too great.

摘要： A correction of temperature errors of the measured value receiver is generally necessary in high-resolution electronic balances. This can be accomplished in a known manner by directly influencing the measured value receiver with the aid of an analogous temperature sensor or by digitizing the output signal of the temperature sensor in a digitizer on the output side and performing the correction in the digital signal processing part. The invention has the task of indicating a circuit which permits the high-resolution digitizer which is present in the balance in any case to be used for digitizing the temperature signal without diminishing its preciseness. A switch (25 in FIG. 1) is provided to this end which feeds the output signal of a temperature sensor (27) to the input of the digitizer (15) in addition to the signal of the measured value receiver (1 . . . 13) at certain times controlled by the digital signal processing unit (22). The sensitive measuring path of the balance is therefore not reversed as it is in the case of customary selector switches, but the temperature signal is added to the measured signal of the balance at certain times and calculated by the digital electronic elements.

摘要： The invention is relative to a method of statically (non-multiplexed) actuating a liquid crystal display which comprises several segments and a common back electrode, using a microprocessor which serially outputs the data to be displayed, and using a serial/parallel converter which statically makes the data to be displayed available for each segment of the liquid crystal display. The invention has the task of achieving recognition of functional error as follows: The data to be displayed is outputted approximately every 0.1 second by the microprocessor and the data for the individual segments and for the back electrode is inverted at every second data output. The failure of components then results in a blinking of the particular segment and is conspicuously indicated in this manner. In the case of alternating voltage actuation of the liquid crystal display, it is advantageous if the clock pulse of the alternating voltage actuation is also inverted at every second data output.

摘要： A balance having a setting means with which the relative precision of the weighing result is to be determined can be set by the user. The balance then adapts automatically to the set relative precision. This adaptation can occur, e.g., in the number of positions displayed, in the step width in the last particular position, in the selection of the integration time, in the filtering of the measured values in the digital signal processing unit, in the frequency of the taking over of the measured value into the display and/or at the time of the emission of the standstill signal or of the measured value release signal.

摘要： An electric inclination meter is built into a high-resolution electric balance with a measured value receiver, a microprocessor for digital signal processing and with a digital display. This inclination meter compensates the inclination-dependent errors of the balance. The inclination meter can have a movable suspended mass or it can have a container which is partially filled with liquid, thus forming a gas bubble. The positional deviation of the movable elements can be picked up optically or inductively.

摘要： The invention discloses an electronic balance comprising a measured value receiver (23) and an electronic evaluation unit (14) having a digital display (10) and an analog display (6), whereby both displays are controlled by the electronic evaluation unit (14). A digital input keyboard (12) is used for inputting the set weight value of a loading. The electronic evaluation unit (14) contains a memory (15) and an arithmetic unit (16) which permit the values indicated in the digital display (10) and in the analog display (6) to be differentiated against each other by the amount stored in the memory (15) so that during a loading procedure the digital display (10) runs from the negative set weight value to 0g and the analog display (6) from 0% to 100%. The analog display (6) consists of adjacent bars (7) which can be shited in their lightness, whereby the length of the individual bars continuously decreases from 0% to 100% of the set weight value, and continuously increases again over 100% of the set weight value.

摘要： In known methods of initializing a balance with counting scale a given quantity of the pieces to be counted is placed on the balance at the same time and the average individual weight is calculated therefrom and used as a base for the following piece counts. In contrast thereto, the invention suggests that the pieces be placed individually on the balance and that the standstill of the balance be waited for after each placing of a piece. This makes it possible to also calculate the standard deviation in addition to the average value and statements concerning the counting precision can be made which are based on known statistical laws, so that counting errors can be avoided.
