A ceramic-metal composite articulation is provided with substantial elimination of wear debris, wherein a ceramic material is provided with superior mechanical properties tailored for articulating with ceramic articulations having high flexural strength (greater than about 700 MPa), high fracture toughness (greater than about 7 MPa1 / 2) and a high Weibull modulus (greater than about 20), in comparison with presently available bio-ceramics such as alumina or zirconia. The mechanical property enhancement enables ceramic materials with greater reliability and significantly reduced in-vivo fracture risk to be obtained. Preliminary in-vitro wear performance, to several million cycles using established test protocols, of head / cup components in a prosthetic hip joint made from these ceramics also demonstrates the ultra low wear characteristics. These material properties substantially eliminate polyethylene (PE) wear debris mediated implant failures by offering an optimal combination of bio-mechanical safety and reliability with ultra low wear performance.

Flaws in information security infest modern software, and pervasive computing has made network systems vulnerable. Information security is constantly endangered by errors in protocol implementations. Testing a protocol implementation for errors directly from a network where a device implementing the protocol resides limits the coverage of protocols tested. In contrast, testing protocols from an access network that internetworks a customer premises with one or more service networks greatly expands the coverage of protocols tested. Accordingly, a method and corresponding apparatus are provided to test from the access network, testing both service network devices and customer premises devices, and the protocols implemented on those devices.

A cable-TV-based network transmits data on relatively high-radio frequency signals from a head end toward clients and transmits data on relatively low radio frequency signals from clients to head end. Radio frequency switch assemblies are distributed hierarchically from head end descending toward the clients. Each radio frequency switch assembly splits a descending path into plural branches, and includes switch units for alternatively blocking or passing low frequency signals from ascending the branches. When low frequency noise is detected at the head end, a noise source is located employing a test protocol in which switch units are sequentially set to block upstream signals, with the head end noise detector determining the effect of each switch disposition. Other types of hierarchical networks use analogous diagnostic methods.
