Abstract: A portable testing device for testing a telecommunications line comprises a control circuit, a test module coupled to the control circuit, the test module including a DSLAM modem, and a relay matrix that includes a series of relays configured to connect with a plurality of wire pairs of the telecommunications line. A first wire pair is coupled to the control circuit via a transceiver and a second wire pair is coupled to the test module, where the relay matrix is coupled to the control circuit via a relay driver. The device, system and method of the present invention can be used to qualify the existing telecommunications line for broadband speed capacity and operation.

Abstract: Disclosed is a Security Indications and Warning (SI&W) Engine usable in conjunction with an audit agent. The audit agent forwards normalized audits to the SI&W Engine. The SI&W Engine groups the normalized audits into related groupings. Gauges are used to count the number of occurrences of audited events. A statistical engine provides statistical representations of the number of events per user, per session and per node. A predetermined number of criteria are defined a particular gauge or gauge pair. There may be many criteria for a particular network. When a predetermined number of criteria within a criteria set are triggered, an indicator is triggered. More complex indicators can use combinations of lower level indicators to provide further indications of potential security threads. Thus, a hierarchical system of gauges, criteria and indicators is used to measure boundary violations and breaches of different barriers.

Abstract: A skeletal tissue stimulator and especially a bone growth stimulator 10 and a circuit 12 adapted to be coupled to the skeletal tissue in a body, and especially bone tissue in the body, whose growth is to be stimulated, which tissue acts as a load 22 for the circuit 12. The circuit 12 has a battery 24 and an oscillator circuit 26 which is adapted to be coupled to the load 22. The oscillator circuit 26 is coupled to a storage device 28 which is charged from the battery 24 and discharged through the load 22. The storage device 28 controls the state of the oscillator circuit 26 which in turn controls current flow from the battery 24 directly through load 22. The bone growth stimulator 10 and circuit 12 are characterized in that all the current provided by the battery 24 must flow through the load 22, either directly from the oscillator circuit 26 or as a result of discharge from the storage device 28.
