摘要:
The control apparatus according to the invention includes a keypad detachable from the control apparatus and including a communication device that facilitates communicating with a personal computer such that the keypad detached from the control apparatus is connected to the personal computer for setting the operations of the control apparatus and, then, the keypad is attached to the control apparatus to make the control apparatus conduct the control operations based on the setting contents set in the keypad. The control apparatus according to the invention facilitates setting the operations thereof in any place different from the place, therein the control apparatus is installed, and reducing the electric power fed to the control apparatus during the setting operation.

A sewing machine having associated modules which can be inserted .[.at will.]. and which are interchangeable in a guide of the housing of the machine. The front side of the plate-shaped modules is visible in the inserted condition of the module and is provided with stitch symbols to which are assigned numbers. On the inside of the modules are arranged memories, preferably in connection with .[.a microprocessor, which are in connection with.]. the microprocessor of the sewing machine when the modules are inserted. By means of keys and a display, the number corresponding to the desired stitch sort can be selected and the control data from the memories of the module will be recalled in the microprocessor of the sewing machine and then used for operation of the sewing machine. .[.By means of simple, strong modules of an advantageous price, even an unskilled operator can select and recall any number of stitch sorts in a simple and safe way when the module with the desired sort of stitch is inserted and the corresponding number is selected..].
摘要:
An embroidering machine includes RAM which stores temporally the embroidering data read out from a memory card; a device which detects attaching or detaching of the memory card; a buffer circuit which makes and breaks a power source and buses for the memory card; an indicator or warning device which indicates the circuit making and breaking; a device for double checking the data sent from the memory card to RAM; and a device which indicates to the operator the presence of a required card. In the detector of the memory card, determined detecting edge terminals of the memory card are made shorter, and when the card is detached the circuits of the detecting terminals are disconnected earlier than the remaining circuits. When the circuit of the detecting terminal is disconnected, the port of the circuit is rendered to be high impedance by the buffer circuit and the power source to the memory card is disconnected before the terminal of the power source and the bus of the memory card are disconnected, so that if the memory card is slipped out from the embroidering machine while processing "ACCESS" of the memory card, the memory IC is not destroyed.

摘要:
A system for increasing transaction security across existing infrastructure is provided. A user bio-metric sensor device is integrated into a credit or debit card. A display unit provides a key, preferably encrypted, upon successful utilization of the sensor device. Included in the key generation mechanism is an indicator of the transaction number or other sequential count indicative of card use. An authorization service decrypts the key in a manner at least partially dependent upon a second sequential count maintained in sync with the first count to determine whether the use is authorized. In one embodiment, a separate credit card reader may be configured to read conventional credit cards, smart cards, and credit cards incorporating such bio-metric sensor devices.

Disclosed herein are methods, apparatus and articles of manufacture that provide modular monitoring, control and device management in a process control system. According to one example a method of replacing a first field device of a process control system with a second field device, wherein the first field device includes a removable data storage device includes extracting the removable storage device from the first field device, removing the first field device from the process control system, installing the second field device into the process control system; and installing the removable data storage device into the second field device.
摘要:
A system having an electric machine, memory device for storing information concerning the electric machine and is attached to the electric machine, and at least one control unit for controlling the operation of the electric machine. Furthermore, the system of the present invention has an interface between the memory device and the at least one control unit so that the at least one control unit reads the information stored in the memory device. The control unit processes the information read from the memory device such that the information becomes verified with default parameters of the system after read-out-thereof. In case the information includes parameters, which do not match in a predefined manner with the default parameters, the control unit is arranged to either automatically, adjust the system in accordance with the information received from the memory device or to prevent start-up of the electric machine or the entire system.
