摘要： A semiconductor device structure is embedded within a semiconductor chip that calibrates a photon-emission luminosity scale by running multiple known currents through the device. The method comprises embedding at least one photon emission device in an integrated circuit having at least one functional device. A control current is applied to the at least one photon emission device. The photon emission intensity produced by the at least one photon emission device is captured. The current density of the at least one photon emission device is calculated. A test current is applied to the at least one functional device. The photon emission intensity produced by the at least one functional device is captured. The current density of the at least one functional device is estimated based on a comparison with the calculated current density of the at least one photon emission device.

摘要： An embodiment for evaluating rules pertaining to an event includes providing a rule trie comprising multiple nodes, wherein match conditions must be met to trigger a given rule, and each match condition corresponds to a different node. An attribute trie is provided for a string attribute, which includes a node sequence having a value. The string attribute is extracted from the event and also has a value. The value of the extracted string attribute and the value of the node sequence are compared, by traversing a path extending along the node sequence. Responsive to determining that the values of the extracted string attribute and the node sequence are the same, notice is provided that the match condition of a particular node of the rule trie has been met by an attribute of the received event.

摘要： A method and system for transport data compression between a server and a client based on patches to the dictionaries used for encoding the data. The method includes requesting the server for data, returning the data and a dictionary patch to the client where data having been compressed based on a previously used dictionary and the dictionary patch, and decompressing the returned data using the dictionary and the dictionary patch. The dictionary patch includes updates to the previously used dictionary. Each dictionary has a dictionary identifier that the server and client use to identify the dictionary in their requests and responses. The identifier might be a unique identification or a network session number. Upon receiving a response, the client updates the previously used dictionary with information in the patch and decompresses the returned data using the updated dictionary.
