Abstract: The present invention provides a circuit for detecting and correcting errors in a bit stream. The circuit consist of a plurality of circuit elements, an least operation circuit means, and at least two logic gates. The logic gates receive inputs from the plurality of circuit elements.

Abstract: A method or process for substituting an inert gas or blend of inert gases for ambient air in the head space of a container filled with leftover oil-based finish prior to sealing the lid. Even a tightly sealed container of leftover paint, stain, varnish, or other oil-based finish, will thicken, gel, or skin over with time. This occurs because the oxygen that is sealed in the storage container continues to react with oil-based finishes. The process involves using an aerosol can filled with the inert gas or blend of gases to displace the oxygen from a container that has leftover oil-based finish in it. After the oxygen is flushed out of a container with the gas, the lid is sealed tightly. The inert gas or blend must be heavier than oxygen and sink down to block oxygen from the liquid surface. Because gas or blend is heavier than oxygen, it will separate the liquid surface from any oxygen that may remain in a container.

Abstract: A method and system for managing the transfer of data into and out of a buffer in a disc drive is disclosed. The operation of the vectored buffer management (VBM) system is administered by a software-based control module. The control module creates and maintains a buffer table by dividing the buffer table into buffer sectors. The buffer sectors are further arranged into buffer segments, or circularly linked lists upon which the buffer table is partitioned. The control module effectuates the transfer by implementing an application module across the buffer table. Once the application module is arbitrarily positioned at an index sector by the control module, data transfer is accomplished when the application module walks through a particular buffer segment identified by the index sector. Specific control of the application module across a buffer segment is administered through host and disc address pointers, which are coupled to host and disc next pointers, respectively.

Abstract: A read-on-arrival scheme for reading data stored on a track of a data storage disc is disclosed. The track is divided into a plurality of sequentially arranged data sectors. Each data sector stores a block of data. A host computer issues a read command requesting retrieval of a segment of data blocks stored on a plurality of the data sectors. The segment may include a target data segment as well as a pre-fetch and post-fetch data segment. The read command specifies a target sector that a transducer is to initially access on the track. Upon receipt of the read command, components of a disc drive move the transducer to the track for access of the segment requested in the command. The disc drive components enable the transfer of data regardless of whether the transducer first accesses a sector located in sequential order prior to or following the target sector.

Abstract: Systems and methods in a disc drive improve data transfer performance by interrupting disc write operations to service read commands.

Abstract: An improved disposable test strip for use in amperometric measurement of analytes in complex liquid media, such as blood, which has three or more electrodes has been developed. This strip is designed so that different electrical potentials can be maintained between a common pseudo reference/counter electrode and each of the other electrodes upon the imposition of a common potential by an amperometric meter. This capability is imparted to the test strip by providing different circuit resistances for each of these other electrodes. The test strip can be utilized to measure a single analyte such as glucose with a background compensation via a “dummy” electrode or it can be used to measure the concentration of multiple analytes.
