Abstract: A collector for a linear beam has a segmented ceramic collector core that permits sustained operation at high temperatures and power densities. The collector provides efficient heat transfer from the while reducing stresses on collector components caused by thermal cycling and comprises a heat sink having a cavity providing interior vacuum walls for the collector a segmented ceramic insulator disposed inside the cavity, and an electrode disposed inside and against the insulator. The insulator comprises sectors separated from one another by gaps, and may be notched in its outer surface for high-voltage stand-off from the sink. The electrode is preferably not brazed/soldered to the insulator. A stage of the electrode may be probeless and comprise a depression. A molybdenum-fabricated heat sink and stage assembly utilizes an insulator constructed from beryllium oxide, aluminum nitride, or alumina; alternatively, a copper assembly, uses an aluminum nitride insulator.

Abstract: A system and method for accessing complex computer based systems initiates a trace and debug session via IP causing the resulting output to be stored in a designated remote server on the Internet which can accept large amounts of information. The trace and debug information subsequently can be accessed from any engineering workstation or personal computer from any other location via the Internet. The invention permits the trace sessions to run independent of any local access and permits several technical people in different locations to access the remote storage server simultaneously or independently.

Abstract: A semiconductor device which receives and transmits data at high speed is tested at operational speed at wafer sort. A probe card includes a high-speed interconnect that couples probe output bonding pads to probe input bonding pads. The high-speed interconnect connects a respective output of a transmitter in the die to a respective input of a receiver in the die while the probe card is connected to the die. A built in self test circuit in the die generates test patterns and compares them for accuracy. The test patterns are routed on the high-speed interconnect from the output of the transmitter to the input of the receiver allowing the data path through the receiver and transmitter in the die to be tested at operational speed before the die is assembled into a package.

Abstract: When copies of digital are made or after use of the digital data, the quality of the digital data is reduced or degraded. The degradation may be in any way suitable to the nature of the digital data. In one embodiment, the content provider which originates the digital data may specify a degradation policy or degradation specification model for the digital data. When the digital data is copied or moved, the copy is degraded according to this specified policy or model. In this manner, the content provider can control the extent to which the end user can copy the material. The end user can make copies limited in number only by the degradation of the digital data.

Abstract: A structure and method for implementing a precision inductive component within a high frequency integrated circuit is disclosed. The inductive component has a structure of multiple conductive layers dielectrically insulated from each other and located above an integrated circuit substrate. The inductive component comprises a spiral-like inductive layer made of a first conductive layer. Additionally, a number of additional ground planes, each patterned out of its own selected conductive layer to minimize an induced eddy current therein thus improving Q (quality factor) under high frequency operation, are employed with either a linear or a rotational offset amongst them to effect a corresponding amount of adjustment of an inductance value of the inductive component. A number of specific design cases are presented with their respective inductance and RF performance parameters.
