  • Patent number: 7343353
    Abstract: A method and system for determining which machine tools to turn off during slow periods to achieve maximum cost savings with minimum cycle time increase. It uses a product demand forecast and a simplified approach to the X-factor theory to provide an objective, analytical model showing the cost savings of potentially turning off different quantities and types of machine tools versus the resulting impact on increased cycle time. This model, which can be visually plotted into a graph, can aid management decision as to the optimum machine tools to turn off while fine-tuning the marginal machine choices can keep cycle time under a predetermined acceptable maximum.

  • Publication number: 20070294445
    Abstract: A method of controlling connection between nodes in a digital interface whereby a first node that is a master node determines a second node to be the master and controls a point-to-point connection or a broadcast connection to another node. The first node having the display device determines the second node to be the master in accordance with a user selection, and transmits a connection command of a predetermined format for transmitting a data stream to the second node. The second node determined as the master in accordance with the transmitted connection command of the predetermined format is allocated with a channel and a bandwidth from an isochronous resource manager (IRM), and performs a point-to-point connection between the second node and the first node to transit the data stream. Thus, the transmission/reception, reproduction, and control of the data stream of the program can be smoothly performed.
