Assignee:

NCR Corporation - Dayton OH

International Classification:

G01G 1952
G01G 2314
G01G 2310

US Classification:

177 1

Abstract:

A method for fast weighing on an electronic scale is disclosed. Periodic samples are taken of the weight of an object placed upon the scale, and succeeding samples are compared for similarity within a given tolerance. The overall range of the scale is divided into various regions based upon frequency of use and reliability of readings. Fewest readings are required for that scale region of most frequent use and greatest reliability, thereby minimizing the time required for completing the weighing of objects with weights falling within that region.

US Classification:

177 50

Abstract:

A method for recalibrating an electronic scale mounted within an enclosure which includes a display and a plurality of switches set to a position representing the calibrated digital output of the scale when the scale is placed in a first and second weighted condition includes the steps of displaying the weight of the weighed condition of the scale, sampling the scale to generate digital signals outputted by the scale when the scale is placed in the first and second weighted condition, comparing the sampled digital signals with the digital signals represented by the setting of the switches, removing the scale from the enclosure when the sampled digital signals are within a predetermined value of the digital signals set up in the switches and displaying the new settings of the switches which corresponds to the sampled digital signals enabling the operator to set the switches accordingly.

US Classification:

235463

Abstract:

There is disclosed a system for decoding data read from a bar code label which includes a filter for detecting the occurrence of a character in the data generated by an optical scanner in reading the bar code label, a first processor for detecting whether the character is valid or a suspect character which may be a valid or a non-valid character and a second processor means for processing the suspect characters to determine if they are valid for use in detecting the numerical characters in the data.

Appl. No.:

6/043933

Inventors:

Gene L. Amacher - Cambridge OH

Assignee:

NCR Corporation - Dayton OH

International Classification:

G06K 710

US Classification:

235463

Abstract:

A symbol decoding system incorporated in a NMOS/LSI chip generates asynchronously binary data in response to the scanning of bars and spaces of the symbol. The binary data may represent each bar or space as a numerical character, a margin or a center band of the symbol. The binary data also includes data identifying the bar or space and if the character generated is valid or invalid. Logic circuits generate a time delay period allowing the binary data to be generated asynchronously during the delay period. At the end of the delay period the binary data is outputted to a utilizing device for selecting the valid data from the data outputted by the decoding system.

International Classification:

G04K 710

US Classification:

235463

Abstract:

A symbol decoding system incorporated in a plurality of NMOS/LSI chips generates data representing numerical characters encoded in the symbol. Scanning means generates signals in response to the scanning of a plurality of bars and spaces, which signals are decoded by a first chip as valid and invalid characters, the valid characters being recognized by a second chip which stores the valid characters and enables a microprocessor chip to receive the valid characters assembled as part of the symbol for processing thereof. Logic circuits enable test numerical characters to be generated in response to test signals outputted by the microprocessor chip.

International Classification:

G01G 1952

G01L 122
G01L 2500

US Classification:

177 50

Abstract:

A scale utilizes a plurality of load cells positioned beneath a weighing platform for determining the weight of objects placed upon the platform. During a weighing operation, each load cell generates a voltage proportional to the response of said cell to the application of a weight to the platform. Each such generated voltage is transmitted serially through a multiplexer and is converted to a digital value by an analog-to-analog converter. These digital values are employed by a microprocessor to determine the weight of the object placed on the weighing platform. The scale is calibrated by weighing a test weight in a plurality of different locations on the weighing platform, and utilizing the individual digital values thus obtained for each load cell in a plurality of simultaneous equations, which are then solved in the microprocessor to provide constant values associated with each load cell, which are used in subsequent weighing operations.

US Classification:

364567

Abstract:

A method for automatically zero balancing an electronic scale includes disabling the display from displaying a "Scale Ready" logo, taking a number of readings from the scale when no weight is placed on the scale, obtaining an average reading for a zero weight condition of the scale by dividing the sum of the readings by the number of readings taken, detecting when two consecutive average readings are within a first predetermined limit, enabling the display to display the "Scale Ready" logo indicating the scale is ready for a weighing operation, taking a number of readings from the scale in response to the displaying the scale ready logo, blanking the display when the readings taken are not within a predetermined value of the zero balance readings, and removing the scale lid from the scale and cleaning the scale to remove dirt or other impediments from the scale in response to the blanking of the display.
