Abstract: There is provided a method of source synchronous sampling, where a first clock signal of a first unit is synchronized to a second signal received from a second unit. The method includes determining a timing control signal on the base of the first clock signal and the second signal, generating an adjusted clock signal by adjusting the timing of the first clock signal corresponding to the timing control signal, and using the adjusted clock signal for sampling a signal received from the second unit. The second signal is a clock signal received from the second unit, the adjusted clock signal is used for sampling this clock signal itself, and a corresponding sampled clock signal is supervised to show proper clock functionality.

Abstract: A biocompatible, resorbable Type II collagen-based matrix is reconstituted from solubilized animal cartilage tissue and used in the culture and growth of cells, such as chondrocyte cells. The matrix is produced by isolating cartilage tissue, solubilizing and reconstituting the cartilage to form a fleece-like material, pressing the fleece-like material to form a sheet-like article, and sterilizing the article. An implantable article for cartilage repair includes chondrocyte cells retained on the matrix.

Abstract: An apparatus for testing an electronic device, in particular an integrated circuit tester and specifically designed for testing memories or logic/memory combinations, provides a multiplicity of pin channels. Each pin channel includes a sequence controller communicating with a decompression control unit. This combination is extremely fast and allows to designate the respective pin channels to an address or a data pin of a memory or to a logic pin of a device under test. A central controller provides the necessary control instructions to instruction memories of the sequence controllers. All sequence controllers assigned to a logic pin execute basically the same program, wherein pin adaptation is performed by a vector memory. In contrast, sequencers assigned to an address pin execute different, pin-specific instructions. The architecture may be easily adapted to varying pin definitions and is based on the "per pin resource" approach. It may also be applied to board testers and other electronic testing devices.

Abstract: An apparatus for generating test signals, preferably for use in an integrated circuit tester, comprises a sequencer, a Vector Memory and a Waveform Memory. The Vector Memory is addressed by the sequencer and contains coded waveform information, which is, in turn, decoded into control information by the Waveform Memory. For this purpose, the data outputs of the Vector Memory control the address inputs of the Waveform Memory. The data outputs of the Waveform Memory control circuitry like a formatter or a comparator which link the waveform information with timing information from one or more edge generators. The formatters, comparators etc. are, in turn, in connection with a device under test. The present apparatus provides full flexibility in the generation of formats and waveforms and, in particular, timing and format changes "on the fly", i.e. without additional delay. Flexibility may be increased if the Waveform Memory is reprogammable.
