Abstract: A method for compressing image information at a high speed and a method for transferring real-time moving images utilizing the same in which scanning of rectangular parallelepiped regions is performed as an extension of three-dimensional Hilbert scanning to improve throughput and to achieve cost reduction. In the method for compressing image information at a high speed, viewed moving images including three dimensional information are converted into one-dimensional serial information one by one using a look-up table associated with rectangular parallelepiped regions in a three-dimensional space, and the converted data is subjected to data compression. In the method for transferring viewed moving images from a server to clients in real-time, data compressed according to the method is transferred through a communication path and the data is decompressed at the clients.

Abstract: An input/output client/server system within a remote control system between general purpose apparatuses provided with TCP/IP compliant communications functions across networks comprising: single or plural general purpose input/output units mounted on the interface boards of remote input/output devices of a general purpose apparatus on the receiver side and provided with a function to give a predetermined response to a command transmitted thereto from a general purpose apparatus on the transmitter side; means for recognizing addresses of the general purpose input/output units provided on the general purpose apparatus on the receiver side; and means for transmitting a command to the general purpose input/output unit by using an IP address of the general purpose apparatus at the destination, an address of the respective interface connected to the respective general purpose input output unit, and the port address of the general purpose input/output unit connected to the general purpose apparatus on the transmitte

Abstract: A bonding defect detecting apparatus is provided for operation in conjunction with an ultrasonic wire bonder using an ultrasonic oscillator driven by a signal. The apparatus has A/D converters for digitally converting a signal waveform of the signal by real-time sampling during a bonding operation. A digital signal processing device is provided for calculating at least one signal characteristic of each of the signal waveforms for each of a plurality of the bonding operation. A data accumulating devices accumulates the at least one signal characteristic for n number of bonding operations of the plurality of the bonding operation. A calculating device calculates an average signal characteristic of the signal characteristics of the n number of bonding operations.
