摘要： The present invention features a method and an apparatus for preventing lift chains from becoming slack in a lift truck with a "man-up" feature installed. Lift trucks are generally those vehicles that feature hydraulically controlled lift masts with a chain supported fork carriage. Operators of these lift vehicles with the remote lift and lower feature are generally lifted and lowered by these masts, known in the trade as a "man-up" condition. It is quite desirable to prevent a slack chain condition in the man-up mast position. The invention features a pressure transducer for monitoring a drop in hydraulic fluid pressure established by the flow control valve that regulates the lowering speed of the mast during the remote mode, i.e., when the fork carriage is being lowered by the operator in the platform attached to the fork carriage. The invention turns off the normally closed load-holding valve when the hydraulic pressure drops below a predetermined value, which stops the flow of hydraulic fluid back into the reservoir. This, in turn, stops the cylinder(s) from lowering and keeps the fork carriage lift chains from becoming slack.

摘要： A method for calibrating an electronic scale includes sampling the output of the scale a predetermined number of times to generate a number of average readings for the weight that is placed on the scale, comparing two successive average readings and selecting the average reading that is within a predetermined weight of the previous average reading, comparing the digital signals sampled representing the selected average reading with the setting of a plurality of settable switches in which each switch position will represent a binary bit and displaying on a display the switch settings which represents the selected average reading of the output of the scale. The operator in response to instructions displayed on the display will place a weighted object on the scale, set one of the switches of the settable switches in response to placing the weight on the scale and set the switches in response to the instructions displayed on the display to store the selected average reading in the settable switches. The method is repeated for a second weight.

摘要： A system and apparatus for compressing redundant and non-redundant binary data generated as part of an operation of a time and attendance terminal in which the data represents the time an employee is present during working hours. The first data entry includes the date and the time the employee operates the terminal together with other data identifying the employee which is stored in a circular buffer. The time of day data includes the hour and the minutes of the keyboard operation. Subsequent data entries include redundant data such as the date and the hour of the terminal operation which may not change and non-redundant data such as the minutes that pertain to the terminal operation together with data identifying the operator. After the redundant and non-redundant data of the first data entry are stored, only the non-redundant data of each subsequent data entry is stored. Upon reading out the non-redundant data from the buffer, a pointer which includes the redundant data such as the date and the hour of the first data entry is added to the non-redundant data read. If the date and/or hour changes, such changed data is stored in the buffer and is transferred to the pointer as the data is read out of the buffer, thus updating the data stored in the pointer.
摘要翻译：一种用于压缩作为时间和考勤终端操作的一部分生成的冗余和非冗余二进制数据的系统和装置，其中数据表示员工在工作时间内的存在时间。第一个数据条目包括员工操作终端的日期和时间以及识别存储在循环缓冲器中的雇员的其他数据。时间数据包括键盘操作的小时和分钟。随后的数据条目包括可能不改变的终端操作的日期和小时等冗余数据以及诸如与终端操作相关的分钟以及识别操作者的数据的非冗余数据。在存储第一数据条目的冗余和非冗余数据之后，仅存储每个后续数据条目的非冗余数据。在从缓冲器读出非冗余数据时，将包括诸如第一数据条目的日期和小时的冗余数据的指针添加到非冗余数据读取。如果日期和/或小时发生变化，则将这些改变的数据存储在缓冲器中，并且随着数据从缓冲器中读出而被传送到指针，从而更新存储在指针中的数据。

摘要： 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.

摘要： A method for polling a plurality of remote processing units includes establishing a table of active and inactive remote processing units, sequentially polling each of the active processing units, at the conclusion of polling the active processing units, polling an inactive processing unit after which all of the active processing units are again polled. This sequence is repeated until all the active and inactive processing units have been polled. If in polling a processing unit, a response to the poll message indicates a change of status of the polled processing unit has occurred, the table is accordingly updated to reflect the current status of the processing unit.

摘要： 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.

摘要： 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.
