Abstract: A system/method is introduced that integrates middleware components without canonicalization of data at runtime, where the system/method receives inputs identifying at least a first and second middleware to be made interoperative (via a communication path between an in-port corresponding to the first middleware and an out-port corresponding to the second middleware), receives an incoming message at the in-port, handles the received message as a plurality of parts and where, for each part, a data-object is created based on an identified type factory, with the in-port populating the data-object with values from corresponding part of the message and passing the populated data object from the in-port corresponding to the first middleware to the out-port corresponding to the second middleware.

Abstract: A system and method is introduced that integrates middleware components without canonicalization of data at runtime. An interface receives inputs identifying at least a first and second middleware to be made interoperative and a configurator configures at least an in-port and an out-port based on a binding and transport associated with the first and second middleware, respectively. Interoperation of the first and second middleware is effected via at least one communication path between the configured in-port and out-port, wherein the communication path allows an incoming message to pass from the in-port corresponding to said first middleware to the out-port corresponding to the second middleware without the creation of an intermediate canonical message.

Abstract: The use of a multi-track format in both optical and magnetic data storage applications provides for a number of improvements to system performance including data density and data transfer rates. However, the full advantage in data density can only be achieved through the use of joint equalization and joint detection. The complexity of implementation of these functions arc addressed with a transform domain equalization architecture and a reduced complexity detection method based on a breadth first search of a time-varying trellis. The trellis results from a one dimensional representation of a two dimensional target response, obtained by arranging samples from adjacent tracks in a sequence that respects the original proximity of the samples.

The wedge has a predetermined shape adapted for receipt in the body opening. The legs each have a notch formed therein. The mounting element is positioned with the resilient fingers in the supporting structure wall opening with the fingers locked to the supporting structure wall and the wedge is received in the body opening to interfere with the mounting element fingers flexing inward, securing the mounting element to the support structure.

Abstract: An adjustable, channel-mount system for mounting a sign to a shelf includes a spring-loaded mounting bracket having a mounting portion moveably connected to a sign-holding portion and an elongated sign-holder. The sign-holding portion of the mounting bracket features at least one channel. At least one securing element configured for engagement with the at least one channel of the sign-holding portion of the mounting bracket is included on a back surface of the sign-holder.

Abstract: A detector system detects values on a storage medium where there is ISI. The symbols are stored as pits in a close hexagonal lattice having u, v, and x dimensions at mutual 60° separations from an individual pit. The value for a particular symbol is determined by generating an estimate for the symbol in each of the u, v, and x dimensions. These estimates are used to generate a decision for the symbol as it is at the intersection of these dimensions. Thus a number of 1-dimensional detectors can be used although the platform is two-dimensional with ISI.

Abstract: A biased-assisted sign mounting system is for mounting a sign to a structure, that includes a vertical upright post having a face having a plurality of vertically extending, spaced apart openings. The mounting system includes a spine adapted to mount to the vertical post. The spine has a face portion. Upper and lower sign mount portions are mounted to the spine. At least one of the mount portions has a biasing element securing portion. Upper and lower arms are mounted to respective upper and lower sign mount portions. The arms each have a pivot defining collinear axes. One of the upper and lower arms has a biasing element securing portion. A biasing element operably connects one of the arms to its respective mount portion such that the arm is pivotal between first and second positions and is biased toward the first and second positions by the biasing element. A floating insert mounts the spine to the upright.

Abstract: The invention provides an apparatus for decoding a coded digital data sequence. The apparatus includes a first Viterbi decoder of a first response type, a first filter and a second filter. The first and second filters are coupled to receive decoded sequences from the first Viterbi decoder. The first Viterbi decoder generates a first decoded sequence from the coded digital data sequence. The first and second filters generate respective first and second error signals in response to receiving the first decoded sequence. The first and second error sequences indicate differences between the first decoded sequence and second and third decoded sequences, respectively. The second and third decoded sequences are probable sequences produced by Viterbi decoders of respective second and third response types in response to receiving the coded digital data sequence.

Abstract: A baud rate digital timing recovery circuit for use in the read channel of a storage device controller is able to operate nominally at the baud rate by recognizing and compensating for oversampling and undersampling conditions. The read channel includes a sample rate converter for interpolating between digitally sampled values and a digital timing recovery loop that detects a phase error in the interpolated signal and adjusts the interpolation interval accordingly. An accumulator circuit generates a modulo-TS interpolation interval value, where TS is the sampling period. Detection circuitry detects when the interpolation interval value has wrapped through its maximum value or minimum value and generates an oversampling or undersampling signal in response. The oversampling and underampling signals are received by an elastic buffer.

Abstract: A data recovery system wherein the data is represented by a sequence of data pulses comprising a predetermined sequence of preamble pulses followed by the sequence of data pulses. The data pulses have desired data pulses and a DC offset component, each one of such data pulses having during the preamble acquisition mode a predetermined period. The system includes a clock for producing clock pulses at a predetermined rate and a negative feedback loop. The negative feedback loop includes a differencing network fed by the data pulses and a feedback signal representative of the DC offset component. The differencing network removes the DC offset component from the data pulses to produce output signal representative of the desired data pulses.
