54 results about "Chronology" patented technology

Chronology (from Latin chronologia, from Ancient Greek χρόνος, chrónos, "time"; and -λογία, -logia) is the science of arranging events in their order of occurrence in time. Consider, for example, the use of a timeline or sequence of events. It is also "the determination of the actual temporal sequence of past events".

Method and apparatus for an intruder detection reporting and response system

A method and apparatus is disclosed for improving the security of computer networks by providing a means operating passively on the network for detecting, reporting and responding to intruders. The system is comprised of a plurality of intruder sensor client computers and associated event correlation engines. Resident in the memory of the client computer and operating in the background is a Tactical Internet Device Protection (TIDP) component consisting of a passive intruder detector and a security Management Information Base (MIB). The passive intruder detector component of the TIDP passively monitors operations performed on the client computer and emits a Simple Network Management Protocol (SNMP) trap to an event correlation engine when it identifies a suspected intruder. The event correlation engine, through the use of a behavior model loaded in its memory, determines whether the user's activities are innocent or those of a perspective intruder. When the event correlation engine is unable to classify a user based on a single trap message, it can request historical information from the security MIB, a database of the operating history of the client computer including a chronology of the illegal operations performed on the client. Once the event correlation engine determines that an intruder is located at an associated client workstation, it generates a status message and transmits the message to all of its subscribers, informing them of the presence and location of a suspected intruder.

Equipment for scanning facial porosity of rock and method thereof

The invention puts forward equipment for scanning facial porosity of rock and belongs to the field of chronology. Pores of rock are filled with a fluorescent material. The equipment comprises an object stage, an objective lens, a polariscope, a focusing lens, a laser scanning unit, a fluorescence incident pore-plate, a photoelectric signal amplifier and a control processing unit. The object stage can move up and down along the vertical direction. The objective lens, the polariscope and the focusing lens are successively arranged from bottom to top above the object stage. The laser scanning unit is arranged at one side of the polariscope and can move. The fluorescence incident pore-plate and the photoelectric signal amplifier are successively arranged from bottom to top above the focusing lens. The photoelectric signal amplifier can receive a fluorescence signal from a laser-activated fluorescent material and convert the fluorescence signal to an electrical signal. The control processing unit can control up-down movement of the object stage, control operation of the laser scanning unit and receive and process the electrical signal from the photoelectric signal amplifier. The invention also puts forward a corresponding method. According to the equipment and the method, facial porosity of rock can be observed accurately and conveniently.
