Abstract: In a threat management platform, a number of endpoints log events in an event data recorder. A local agent filters this data and feeds a filtered data stream to a central threat management facility. The central threat management facility can locally or globally tune filtering by local agents based on the current data stream, and can query local event data recorders for additional information where necessary or helpful in threat detection or forensic analysis. The central threat management facility also stores and deploys a number of security tools such as a web-based user interface supported by machine learning models to identify potential threats requiring human intervention and other models to provide human-readable context for evaluating potential threats.

Abstract: Apparatus, methods, and articles of manufacture are claimed for processing stored and forwarded code comprising the transferring of the stored and forwarded code from a storage area to a transfer component, wherein the code is passed to a proscribed code scanner. The proscribed code seamier indicates the presence or absence of proscribed code, which may be a virus, confidential material, harassing material, etc. and provides the indication back to the transfer component, wherein the code may be quarantined or otherwise intercepted depending upon the results of the scan. The especially preferred embodiments operate within a UNIX sendmail environment.

Abstract: A back-up battery system is provided for use with a real-time clock of an on-board device controller. In its normal operation, the real-time clock (RTC) is powered by a primary power source, such as a vehicle battery. When the primary source is interrupted, the back-up battery system is invoked to provide back-up power to the RTC. The system includes a low voltage dry cell battery mounted within a fuse component configured for electrical engagement within the vehicle fuse block. In one embodiment, a relay is interposed between the fuse component and the RTC to make and break the back-up power circuit in response to the state of the primary power source. In another embodiment, the battery within the fuse component is replaceable, with the fuse component including a base and a removable cap. In still another embodiment, the battery within the fuse component is a rechargeable battery, and the back-up power system includes a recharging circuit operable with the primary power source.

Abstract: An electronic digital control system monitors and controls the operation of an engine fueling system. Signals activating injection for a plurality of cylinders are transmitted through a single line to a driving circuit for a single injector solenoid valve, while signals controlling accumulator fuel pumps are transmitted to pumping control solenoids. Injection signals are controlled to vary fuel delivery rate during an injection event. A back EMF sensing circuit measures valve opening delay and the control system compensates for valve delay. Variable cylinder-specific delays in the injection solenoid output signal pulses are programmed to compensate for a varying fuel line length to each injector nozzle. At startup, the control system pulses the pumping control solenoids to begin pressurizing the accumulator before engine angular position sensors provide an accurate indication of engine angular position to allow precise timed control of the pump.

Abstract: The absolute angular position of an internal combustion engine is determined by monitoring engine intake manifold pressure at a strategic position in the manifold affected most significantly by the intake event of a predetermined cylinder. A significant or maximum depression in manifold pressure over each engine cycle then is indicative of the intake stroke of the predetermined cylinder.
