摘要:
A method and system and related computer program products are described for identifying an object of service comprising the initial step of generating and storing a static composite identifier representing a state of the object of service. Then, whenever it is desired to identify the object of service, the steps are carried out of: generating a dynamic composite identifier representing a current state of the object of service; locating and retrieving the stored static composite identifier, and searching a database for a match with an object of service recorded therein using either the static or the dynamic composite identifiers, or both.

A device for needle biopsy is provided. The device includes a handle member having proximal and distal portions. A proximal handle member is disposed to the proximal portion of the handle member and a distal handle member is disposed to the distal portion of the handle member. A sheath lumen is disposed within the handle member and extends from the distal portion of the handle member. A needle housing member is partially disposed to the proximal portion of the handle member and a needle is disposed within the sheath lumen. A plurality of protrusions are disposed upon the needle.

The present invention relates to systems and methods for minimizing or eliminating diffusion effects. Diffused regions of a segmented flow of multiple, miscible fluid species may be vented off to a waste channel, and non-diffused regions of fluid may be preferentially pulled off the channel that contains the segmented flow. Multiple fluid samples that are not contaminated via diffusion may be collected for analysis and measurement in a single channel. The systems and methods for minimizing or eliminating diffusion effects may be used to minimize or eliminate diffusion effects in a microfluidic system for monitoring the amplification of DNA molecules and the dissociation behavior of the DNA molecules.

Methods and apparatus consistent with the invention provide the ability to organize and build understandings of machine data generated by a variety of information-processing environments. Machine data is a product of information-processing systems (e.g., activity logs, configuration files, messages, database records) and represents the evidence of particular events that have taken place and been recorded in raw data format. In one embodiment, machine data is turned into a machine data web by organizing machine data into events and then linking events together.

Silicon carbide substrate wafers are prepared by transferring a monocrystalline silicon layer from a donor wafer onto a handle wafer, the silicon layer being implanted with carbon and annealed to form a monocrystalline SiC layer prior to or after transfer of the silicon layer.
摘要:
A process is provided for etching a silicon-containing substrate. In the process, the surface of the substrate is cleaned. A film of alumina is deposited on the cleaned substrate surface. A silver film is deposited above the film of alumina. An etchant comprising HF is contacted with the silver film.
摘要:
A non-volatile memory chip package is prepared for surface mounting to a substrate in a solder reflow process by programming erased blocks to higher threshold voltage levels, to improve data retention for blocks which are preloaded with content, such as by an electronic device manufacturer. Following the surface mounting, the previously-erased blocks are returned to the erased state. The threshold voltage of storage elements of the preloaded blocks can change during the surface mounting process due to a global charge effect phenomenon. The effect is most prominent for higher state storage elements which are surrounded by erased blocks, in a chip for which the wafer backside was thinned and polished. The erased blocks can be programmed using a single program pulse without performing a verify operation, as a wide threshold voltage distribution is acceptable.
摘要:
Methods and apparatus consistent with the invention provide the ability to organize, index, search, and present time series data based on searches. Time series data are sequences of time stamped records occurring in one or more usually continuous streams, representing some type of activity. In one embodiment, time series data is organized into discrete events with normalized time stamps and the events are indexed by time and keyword. A search is received and relevant event information is retrieved based in whole or in part on the time indexing mechanism, keyword indexing mechanism, or statistical indices calculated at the time of the search.
