Abstract: A method for generating alerts from a periodically sampled system is disclosed. The method includes maintaining a sampling window having a predefined number of most-recently collected samples. The method further includes calculating an alert value, the alert value representing a ratio of a first value to a total number of samples in the sampling window, the first value representing a total number of samples in the sampling window having parameters exceeding a predefined sample alert threshold. The method additionally includes generating a first alert if the alert value exceeds a predefined alert threshold.

Abstract: An authentication processing apparatus for performing authentication based on a user's normal operation is provided. The authentication processing apparatus performs the authentication processing on the basis of operation information obtained from normally operating an information processing apparatus. Operation information obtained from operating an input unit by the user, such as a keyboard inputting mode, is obtained to serve as operation information, and the obtained operation information is checked against operation information registered in a database to perform authentication. Authentication is thus made possible without requiring the user to perform the special input processing for the authentication processing. Authentication is performed taking into consideration a plurality of pieces of operation information. With the checking processing in which less dispersed data is weighted, user authentication with high accuracy is made possible.

Abstract: Embodiments of the invention may reduce timing and spatial distortion in Picosecond Imaging and Circuit Analysis (PICA). In one embodiment, a method of determining distortion in a circuit image comprises: defining potential photon emission areas in the circuit image using a layout database, determining ideal photon emissions over the potential photon emission areas, measuring photon emissions for the potential photon emission areas, comparing the ideal photon emission with the measured photon emissions, and producing a mathematical model that predicts the amount of spatial distortion over the potential photon emission area.

Abstract: A measuring transducer having a sensor (2) transforming a measured parameter, recorded by the sensor, into an electrical sensor signal (3), a signal processing unit (6), adapted to convert the sensor signal into a measurement signal (7) and to generate an error message signal (11), and a data interface (8) transmitting the measured signal and the error report signal. In order to enable error events external to the measuring transducer (1) to be recorded in a simple manner, the measuring transducer includes a control input (15) other than the data interface (8). This control input is adapted to transmit an error report signal (11) that is generated.

Abstract: The present invention enable to separate source signals from mixture signals into which the source signals are mixed temporally and spatially, where the number of source signals is more than or equal to the number of mixture signals. A signal storing portion 12 stores the mixture signals input into a signal input portion 11, and a formulation portion 131 in a signal separation portion 13 extracts the mixture signals stored in the signal storing portion 12 and formulates them as an operation expression using a basis matrix composed of plural small matrixes that consist of bases with time symmetry. A learning algorithm application portion 132 applies a learning algorithm based on overcomplete representations, a mixture matrix calculating portion 133 calculates a mixture matrix, a source signal estimating portion 134 estimates source signals separated from the mixture signals, and an output portion 14 outputs the calculated mixture matrix and the estimated source signals.
