A system and method for detecting malware by modeling the behavior of malware and comparing a suspect executable with the model. The system and method extracts feature elements from malware-infected applications, groups the feature elements into feature sets, and develops rules describing a malicious probability relationship between the feature elements. Using malware-free and malware-infected applications as training data, the system and method heuristically trains the rules and creates a probability model for identifying malware. To detect malware, the system and method scans the suspect executable for feature sets and applies the results to the probability model to determine the probability that the suspect executable is malware-infected.

A system and method for detecting malware on a limited access mobile platform in a mobile network. The system and method uses one or more feature sets that describe various non-executable portions of malware-infected and malware-free applications, and compares a application on the limited access mobile platform to the features sets. A match of the features in a suspect application to one of the feature sets provides an indication as to whether the suspect application is malware-infected or malware-free.

A reprogrammable packet processing system for processing a stream of data is disclosed herein. A reprogrammable data processor is implemented with a programmable logic device (PLD), such as a field programmable gate array (FPGA), that is programmed to determine whether a stream of data applied thereto includes a string that matches a redefinable data pattern.

An apparatus comprises a receiver (203) which receives a microphone signal from a microphone (201) where the microphone signal comprises a test signal component corresponding to an audio test signal. A divider (215) divides the microphone signal into a plurality of test interval signal components, each of which corresponds to the microphone signal in a time interval.

The approach may allow for a reliable interference estimate to be generated while maintaining low complexity.

Techniques are described for detecting and distinguishing among ischemia, hypoglycemia or hyperglycemia based on intracardiac electrogram (IEGM) signals. In one technique, these conditions are detected and distinguished based on an analysis of: the interval between the QRS complex and the peak of a T-wave (QTmax), the interval between the QRS complex and the end of a T-wave (QTend), alone or in combination with a change in ST segment elevation. By exploiting QTmax and QTend in combination with ST segment elevation, changes in ST segment elevation caused by hypo / hyperglycemia can be properly distinguished from changes caused by cardiac ischemia. In another technique, hyperglycemia and hypoglycemia are predicted, detected and / or distinguished from one another based on an analysis of the amplitudes of P-waves, QRS-complexes and T-waves within the IEGM. Appropriate warning signals are delivered and therapy is automatically adjusted.

Techniques for detecting coagulum formation on an ablation electrode make use of an ablation electrode that is connected to a radio-frequency (RF) generator capable of applying a small amount of RF energy that is not cell destructive. The temperature at the ablation electrode can be precisely measured using a thermosensor incorporated within the ablation electrode. Before and after actual ablation, a low, non-cell destructing (non-ablating) amount of RF energy is generated at the ablation electrode. If no coagulum has formed during actual ablation, the temperature increase during this test application will be similar before and after the ablation attempt. If coagulum has formed during the actual ablation, however, the temperature increase during the test application after ablation will be significantly higher.

A repeater station 10 detects whether or not an abnormality exists in each of signal light and monitor light having arrived from a terminal station 1 or a repeater station 20, and controls, according to the result of detection, operations of optical amplifiers 11 and 12 and the monitor light. In the case where both of the signal light and monitor light arriving from the terminal station 1 via the optical transmission line for the downstream direction are abnormal, the optical amplifier 11 for the downstream direction stops its amplifying operation by itself, whereas a monitor control apparatus 13 stops the amplifying operation of the other optical amplifier for the upstream direction and also stops transmitting the monitor light to the terminal station 1 in the upstream direction.
