摘要:
A method and associated apparatus are described that enables unattended, remotely distributed appliances, such as vending machines, utility meters, thermostats and kitchen appliances (ovens, washing machines, refrigerators, etc.) to be connected inexpensively to each other and to a centrally located server. The apparatus 1) uses relatively simple “personality” modules to adapt the apparatus to the application in combination with a sophisticated core module that provides the intelligence needed to process data locally, to format that data and to transfer it to a remote server and 2) uses existing Internet-based communication links, thereby avoiding the costly proprietary links used with current state-of-the-art solutions.

摘要:
A powered Ethernet connection is provided between two devices connected by an Ethernet connection that provides data communication between the devices. Electrical power is applied to the Ethernet connection at the first device, and extracted from the Ethernet connection at the second device. The extracted power is used to power the second device.
摘要:
The invention provides improved methods and apparatus for control using field and control devices that provide a virtual machine environment and that communicate via an IP network. By way of non-limiting example, such field device can be an “intelligent” transmitter or actuator that includes a low power processor, along with a random access memory, a read-only memory, FlashRAM, and a sensor interface. The processor can execute a real-time operating system, as well as a Java virtual machine (JVM). Java byte code executes in the JVM to configure the field device to perform typical process control functions, e.g., for proportional integral derivative (PID) control and signal conditioning. Control networks can include a plurality of such field and control devices interconnected by an IP network, such as an Ethernet.
