A modular intrusion detection system that includes a base unit having a primary intrusion detection device and a housing. The primary housing includes a base housing section and an outer cover. The base housing section includes a first mounting interface. A plurality of different secondary housing sections having a second mounting interface which can be attached to the first mounting interface of the base housing section are provided. The secondary housing sections may have a functional device, such as a CCD camera or a microphone, associated therewith. The camera or microphone may be activated to an alarm signal generated by the intrusion detection device. A plurality of different base units, each having an intrusion detection device, may also be provided wherein each of the base units is attachable to each of the secondary housings, and secondary devices associated therewith, to provide flexibility in assembling individual devices.

An organic light emitting device is provided. The device has an anode, a cathode, and an organic layer disposed between the anode and the cathode. The organic layer comprises an emissive material having a transition metal and two or three bidentate ligands, which may be photoactive ligands. The bidentate photoactive ligands may be bound to the transition metal through a carbon-metal bond and a nitrogen-metal bond to form a cyclometallated ring. The organic layer may have the formula LXa-(L)bM, wherein X is a linking group that links two or more ligand L and M is a metal.

摘要:
Detection of network devices (e.g., stealth devices) and mapping network topology are performed via network introspection by collaborating endpoints/nodes. The method includes receiving (e.g., by a node on a network) an assignment to be a supernode that will manage multiple agents of a subnetwork within an overall network. This assigned supernode instructs two or more of the agents to perform a set of network traffic fingerprinting tests of the subnetwork by passing information across the subnetwork to each other. The supernode receives results of the tests from the clients and detects one or more intermediate devices located between the clients based on an effect of the intermediate devices on the information passed between the clients. The supernode can further map the topology of the subnetwork (including the detected devices) which can be used in mapping the overall network topology.
