摘要:
An associative, or content-addressable, memory device and method based on waves is described. In this invention, arbitrary inputs are written as patterns which are interpreted as values of complex waves, discretized or analog, on one or more buffers. Information is transported via wave propagation from the buffers to a cortex or to multiple cortices, where the patterns are associated using a mathematical operation for storage purposes or de-associated through the corresponding inverse operation for retrieval purposes. The present associative memory is shown to emulate important behavioral properties of the human brain, including higher-brain functions such as learning from experience, forming generalizations or abstractions, and autonomous operation.

摘要:
An associative, or content-addressable, memory device (101) and method based on waves is described. In this invention, arbitrary inputs are written as patterns which are interpreted as values of complex waves, discretized or analog, on one or more buffers (102,104). Information is transported via wave propagation from the buffers (102,104) to a cortex (103) or to multiple cortices, where the patterns are (1) associated using a mathematical operation for storage purposes or (2) de-associated through the corresponding inverse operation for retrieval purposes. The present associative memory is shown to emulate important behavioral properties of the human brain, including higher-brain functions such as learning from experience, forming generalizations or abstractions, and autonomous operation.

摘要:
According to the present disclosure, an Intelligent Electronic Device (IED) such as a digital relay or protection device for Substation or Distribution Automation is conceived in a modular way, comprising distinct modules dedicated to distinct tasks and having dedicated housings or casings, which modules are mechanically arranged on a common support and both visible and accessible from outside of the IED at all times. Modules for signal input (process interface modules comprising a number of input terminals and signal processing (process data handling modules for evaluating signals in view of an automated protection function or as a communication gateway) define the basis of a modular arrangement that is not delimited by any prefabricated cover or cabinet and that allows for a quasi-unlimited flexibility regarding the number of modules and an easy replacement or extension of individual modules.
