Methods for combating malicious software

ActiveUS20090077664A1Memory loss protectionError detection/correctionCausal treeData segment
A method for combating malware monitors all attempts by any software executing on a computer to write data to the computer's digital storage medium and records details of the attempts in a system database having a causal tree structure. The method also intercepts unauthorized attempts by executing objects to modify the memory allocated to other executing objects or to modify a selected set of protected objects stored on the digital storage medium, and may also intercept write attempts by executing objects that have a buffer overflow or that are executing in a data segment of memory. The method may include a procedure for switching the computer into a quasi-safe mode that disables all non-essential processes. Preferably, the database is automatically organized into software packages classified by malware threat level. Entire or packages or portions thereof may be easily selected and neutralized by a local or remote user.

Digital cueing receiver

ActiveUS7136009B1Low costReduce complexityCommunication jammingRadio wave reradiation/reflectionRadio receiverAnalog delay line
A digital cueing radio receiver system embodied using digital memory in lieu of analog delay lines and thereby avoiding delay line implementation difficulties. The cueing receiver system includes a wideband receiver portion providing an output signal employed for tuning a narrowband receiver portion of the system. Signal delay enabling use of the wideband receiver portion output signals for tuning the narrow band receiver portion selection frequency is provided by a digital memory circuit operating on analog-to-digital converted samples of input signal data of the receiver system. Approximated unity value related mathematical multiplication free Kernel function values are employed in the Fourier transformation. Avoidance of analog delay line-elements in embodying the system is a significant practical advantage of the invention.
