The method includes providing one or more test requirements categories, associating one or more first data elements with each requirements category, associating one or more second data elements with a degree of exposure of the target system to the one or more threats, comparing the first data elements to the second data elements to determine, based on predetermined rules, composite data elements for each requirements category; and selecting, based upon predetermined rules, a level of risk of the composite data elements as a baseline risk level for each requirements category.

A method and system detects and diagnoses faults in heating, ventilating and air conditioning (HVAC) equipment. Internal state variables of the HVAC equipment are measured under external driving conditions. Expected internal state variables are predicted for the HVAC equipment operating under the external driving conditions using a locally weighted regression model. Features are determined of the HVAC based on differences between the measured and predicted state variables. The features are classified to determine a condition of the HVAC equipment.

Some embodiments of the invention may operate to measure a first output performance metric value associated with a current operation frequency of a processor, to set a trial operation frequency of the processor, and to measure a second output performance metric value associated with the trial operation frequency. If the measured performance variation is less than a specified acceptable performance variation, the trial operation frequency may be selected as a subsequent determined operation frequency.

Systems and methods for development testing of vehicles and components are disclosed. In one embodiment, a system includes a position reference system and a command and control architecture. The position reference system is configured to repetitively measure one or more position and motion characteristics of one or more vehicles operating within a control volume. The command and control architecture is configured to receive the repetitively measured characteristics from the position reference system, and to determine corresponding control signals based thereon. The control signals are then transmitted to the one or more vehicles to control at least one of position, movement, and stabilization of the one or more vehicles in a closed-loop feedback manner. The system may further include a health monitoring component configured to monitor health conditions of the one or more vehicles, the control signals being determined at least in part on the health conditions.

A chopped Hall effect sensor topology includes a switched Hall plate, an amplifier responsive to an output of the switched Hall plate and a filter stage responsive to the output of the amplifier and including an anti-aliasing filter and a selective filter that is tuned to the modulation frequency.

Network device testing equipment capable of testing network devices using small size packets and for a transferring ability and a filtering ability at a media speed is described. A configuration is adopted in which a Field Programmable Gate Array (FPGA) included in a transmitter or receiver on one or both of transmitting and receiving sides is connected directly to a physical layer chip of a network and computers on both the transmitting and receiving sides are connected thereto. Each of the FPGAs of the transmitter and receiver has a circuit which has an integrated function of transmitting a packet pattern generation function and a packet-receiving function, thereby enabling a test and an inspection in real time. When inspecting the filtering function, a hash table storing therein a hash value and a list of occurrence frequencies for hash values is utilized. In order to avoid the hash values of different packets from having a same value, the hash function is configured so as to avoid that the same hash value is given to different packets or, when packet values have a common hash value, the packet is re-shaped into a packet having a different hash value.

A near field apparatus comprises a Radio Frequency (RF) coil including at least one of a shorting bridge from a first point to a second point along an electrical path of the RF coil and / or a discontinuity in the electrical path of the RF coil.

A method and apparatus for monitoring the condition of a utility meter by obtaining a temperature value associated with the meter, determining whether the temperature value crosses a threshold, triggering an action if the threshold value is crossed. In another form the temperature can be used as a fault parameter to determine the condition of a utility meter.

A method is designed for measuring a magnetic offset of a geomagnetic sensor equipped in a portable information terminal apparatus having a storage. The geomagnetic sensor has a magnetic sensitivity to a geomagnetic field and is affected by magnetization to cause the magnetic offset. In the method, an output of the geomagnetic sensor is measured to successively provide measurement data of the geomagnetic field from the output of the geomagnetic sensor. The measurement data is stored in the storage. The measurement data is read out from the storage when a number of the measurement data stored in the storage reaches a predetermined number, and an offset value of the magnetic offset is estimated based on the predetermined number of the measurement data read out from the storage.

The three-dimensional application program framework structure provides a framework comprising functions and management of the environment of the system and events to be implemented by the user (developer), and the developer can easily expand the graphic user interface (GUI) and an actual modeling function as required, and user model. In addition, by using an automatic test system based on the framework, it is possible to record the function-execution history of the user and to automatically generate a test case, and to thereby test the functioning of the application software through the use of the test case regardless of changes in the source code and the GUI.

A method for compensating for a temperature-related error in an electrochemical sensor without using separate sources of temperature measurement by measuring sensor current, temporarily lowering sensor voltage to a first level below a reaction-sustaining threshold, measuring a first offset current, adjusting sensor voltage to a second level below the threshold, measuring a second offset current, calculating a difference between the offset currents, deriving a temperature compensation value from the difference based on empirical data, and adding the value to the measured sensor current. A computer system may execute the method as an algorithm stored in memory, provide automatic control of the sensor, and provide continuous display of corrected output values.
