Abstract: A valve device (1) for a medical system comprises a valve housing (10), an inlet port (102) arranged on the valve housing (10), an outlet port (103) arranged on the valve housing (10), a flow duct (12) extending through the valve housing (10) connecting the inlet port (102) and the outlet port (103) to allow for a fluid flow (P) through the valve housing between the inlet port (102) and the outlet port (103), and a closure element (11) arranged on the valve housing (10) for selectively opening and closing the flow duct (12).

Abstract: An optical intrusion detection system includes an electromagnetic radiation detector located within the chassis of a personal computer or the like. The EM detector, such as a photodiode or phototransistor, detects EM radiation when the chassis is opened (allowing a person to modify or remove the contents thereof). The EM detector sends a detection signal to a latching mechanism that latches the signal and maintains the signal even after the chassis is closed. A detection component is provided which supplies the detection signal as a data signal to a network administrator terminal coupled to the personal computer where the optical intrusion detection system is installed. A feature of the detection system of the present invention is that intrusion into the chassis is detected silently and without alerting the individual opening the chassis.
