摘要： Packets received at a network appliance are classified according to a packet classification rules based on flow state information maintained by the network appliance and evaluated for each packet as it is received at the appliance on the basis of OSI Level 2-Level 4 (L2-L4) information retrieved from the packet. The received packets are acted upon according to outcomes of the classification; and the flow state information is updated according to actions taken on the received packets. The updated flow state information is then made available to modules performing additional processing of one or more of the packets at OSI Layer 7 (L7).

摘要： Various embodiments of methods and systems for determining the thermal status of processing components within a portable computing device (“PCD”) by measuring leakage current on power rails associated with the components are disclosed. One such method involves measuring current on a power rail after a processing component has entered a “wait for interrupt” mode. Advantageously, because a processing component may “power down” in such a mode, any current remaining on the power rail associated with the processing component may be attributable to leakage current. Based on the measured leakage current, a thermal status of the processing component may be determined and thermal management policies consistent with the thermal status of the processing component implemented. Notably, it is an advantage of embodiments that the thermal status of a processing component within a PCD may be established without the need to leverage temperature sensors.

摘要： The aspects enable a computing device or microprocessor to adjust the operations of a processor in view of a current processor workload based on a histogram-like data structure. A histogram-like data structure characterizing one of processor busy and/or idle durations or busy/idle ratios is generated at runtime and used to model the processor workload. The processor workload is used to predict future processing requirements and to adjust the processor's operations such that they are commensurate with the processing and workload requirements. The histogram-like data structure may alternatively be used to estimate a current quality of service (QoS) of a communication link so that link management actions may be taken.

摘要： Electrolyte analyzers are used in a variety of ways, and problems vary from reagent deterioration due to reagent replenishment, mixing of foreign substances during reagent replenishment, electrode deterioration due to the passage of the validity date, to the operator's inputting errors. It is thus necessary to judge abnormalities of measured values resulting from such inappropriate usage, based on the fluctuation patterns of the results of daily electrolyte calibration.The fluctuation patterns of each measured item are extracted from the results of daily electrolyte calibration. The electromotive force balance ratio between the internal standard solution and high/low-concentration standard solutions is calculated as well as its fluctuation pattern. The obtained fluctuation patterns are compared against atypical fluctuation patterns stored in the electrolyte analyzer. When any of the extracted patterns matches any of the atypical patterns, the analyzer activates an alarm.

摘要： Various methods of authenticating an access terminal are presented in the case where the access terminal is roaming within a visited network. An access terminal sends a device authentication message to a visited validation server or a home validation server, where the device authentication message includes an access terminal identifier and authentication data generated at least in part using the validation key. In some embodiments, the authentication data may include a digital signature by a validation key associated with the access terminal identifier. Such a signature can be authenticated by either the visited validation server or the home validation server. In other embodiments, the authentication data may include an access terminal authentication token sent to the visited validation server. The visited validation server can authenticate the device authentication message by comparing the access terminal authentication token with an access terminal authentication token obtained from the home validation server.
