Abstract: Techniques are described for presenting events detected by a monitoring system. A system receives a selection of a particular time period, identifies security events detected by a monitoring system during the selected time period, and classifies a subset of the identified security events as abnormal events. The system further generates a density of the identified security events over the selected time period, generates a density of the subset of the identified security events classified as abnormal events, and identifies monitoring system data associated with the selected time period. The system additionally generates a graphical representation of the density of the identified security events, the density of the subset of the identified security events classified as abnormal events, and the identified monitoring system data, and provides the graphical representation for display.

Abstract: A valve (20) is provided that selectively controls flows of fluid through a valve opening (50). The valve (20) includes an elastically resilient valve member (54) that is seated in a member pocket (52) with a valve flap (76) that covers the valve opening (50). The valve flap (76) substantially prevents flows of fluid in one direction through the valve opening (50), but permits flows of fluid in the other direction.

Abstract: A method for extracorporeal blood heating to effect whole body hyperthermia, which utilizes a hemodialyzer with a sorbent suspension in the dialysate, a blood pump and a heat exchanger--in addition to various probes and catheters and heated anterior and posterior blankets for the patient--to effect extracorporeal treatment without adverse effect on blood physiology and without the need for general anesthesia. Blood returning to the body is heated to at least about 46.degree. C. Incorporation of hemodialysis into the blood heating treatment solves at once several problems which plagued prior art hyperthermia techniques: it rectifies any imbalances of sodium, potassium, magnesium, bicarbonate or phosphate, and may remove toxins incident to necrosis of tumors and virally infected cells. Hyperthermia protocols with sorbent--based dialysis of blood thus avoid the various serious side effects which complicated--even to the point of death--the hyperthermia treatments known from the past.

Abstract: A method for extracorporeal blood treatment which utilizes a hemodialysis machine capable of heating the dialysis fluids to 48.degree. C., a hollow-fiber, high efficiency hemodialyzer, and a tubular heat exchanger--in addition to various probes and catheters and heated anterior and posterior blankets for the patient--to effect extracorporeal treatment without adverse effect on blood physiology and without the need for general anesthesia.
