A method and apparatus is disclosed to prepare a sample or a plurality of samples for subsequent analysis. A single sample deposition apparatus, and a multiplexed sample deposition apparatus are shown. The apparatus allows for a system that can provide a high throughput deposition of samples to form chromatograms by discrete droplet deposition or as continuous traces. The system can achieve high resolution digitization by pulsing the fluid emanating from the chromatographs by applying a voltage to the target plate that operates at frequencies equal to or greater than about 10 Hz, and up to and including about 1 KHz. The system also allows for analogue recording (i.e., approaching infinite resolution) by nebulizing the fluid coming from multiple columns and simultaneously collecting it on a target plate as a continuous trace.

A digital audio data reproducing system includes a digital audio data reproducing apparatus having a record medium, a detection part for the record medium and a processing unit; an analog record player; and a rotation detecting apparatus for sensing the speed and sense of revolution of an analog record. The rotation detecting apparatus is provided for easily controlling audio data in the other electrical appliances by an analog record in which audio data is stored. The scratch operation of the analog record together with the reproduction of the analog record by a player allows the rotation body to be rotated around a shaft in accordance with the rotation of the analog record. A rotary encoder senses the speed of revolution and the direction of rotation for the rotation body to output pulse signals, and the audio data in the data reproduction apparatus are scratch-controlled on the basis of the pulse signals.

An enhanced mechanism for providing data protection for variable length records utilizes high performance block storage metadata. In an embodiment, an emulated record that emulates a variable length record, such as a Count-Key-Data (CKD) record or an Extended-Count-Key-Data (ECKD) record, is generated by a Host Bus Adapter (HBA) of a mainframe system. The emulated record comprises a sequence of extended fixed-length blocks, each of which includes a data block and a footer. A confluence of the footers defines a high performance block storage metadata unit associated with the emulated record and includes a checksum that covers all data blocks and all footers of the entire emulated record. In one embodiment, the checksum is checked during transit of the emulated record between a HBA and a storage subsystem (e.g., by the HBA when the emulated record is received from the storage subsystem, and / or by a switch in the data transfer path), during a hardening step when writing the emulated record to a disk, and / or during a verification step when reading the emulated record from the disk.

The Title III Digital Recording System is an invention to satisfy the digital recording requirements of court ordered wiretapping in accordance with newly generated legislation (CALEA, the Communication Assistance for Law Enforcement Act), and to replace inefficient Title III analog recording techniques with digital recording on inexpensive Compact Disc (CD) media. Title III refers to a generally accepted reference for legal wiretapping (telephone intercepts). The Title III Digital Recording System is a recorder that is compliant with requirements set forth in the U.S. Code Title 18, sections 2510 et al. It provides a complete capability to support legally authorized wiretaps, and provides many features to assist the Law Enforcement professional in conducting the wiretap recording operation. The Title III Digital Recording System uniquely applies conventional Compact Disc (CD) recording techniques to specific Law Enforcement problems. The Title III Digital Recording System allows the Law Enforcement professional to record high-fidelity intercepts on digital recording media, vs. analog tape recordings. It provides for 20 hours of recording on a single CD media. The recording technique utilizes UDF (Universal Data Formatting) on the CD's to optimize record time and data integrity. Three digital recordings are performed simultaneously: Primary Evidence CD, backup Evidence CD, and Working CD. The CDs can be played back in conventional CD R / W players supporting the Universal Data Format using Commercial-Off-The-Shelf (COTS) playback software.

An information recording and reproducing apparatus is capable of dubbing a video and audio signal onto a digital recording medium in a short time, using a control signal recorded on an analog recording medium together with the video and audio signal. The information recording and reproducing apparatus includes a control signal detecting part for detecting a control signal recorded on the analog recording medium, a control part, and the like. When a dubbing instruction is input, the control part instructs a recording part to start a dubbing operation of recording the video and audio signal reproduced by a reproducing part onto the digital recording medium, and during the dubbing operation, when a non-recorded region where the control signal is not recorded on the analog recording medium is detected, the control part instructs the recording part to temporarily stop recording onto the digital recording medium.

A signal reconstruction technique is used to correct for wow and flutter in analog audio recordings. Elements of the recording are used to generate a signal for correcting the output. Involves locating modulated entities such as bias signal (e.g. frequency-modulated, amplitude-modulated, or phase-modulated entities) in the recording, extracting them, and utilizing them as a carrier to synchronize to a master clock, using the irregularity of the anomaly to indicate the speed and pitch information to be corrected. A carrier frequency is determined and applied to a digitized form of the recording. This may be performed even in the absence of a prescribed reference code or tone, such as a pilot tone laid down purposefully at the moment of recording. In the case of signals presumed to have an error in the carrier, a corresponding signal is buffered, and in the case of a presumed error, a last known signal is used for the duration of the error.

Nested inductor arrays magnetically modulate an analog audio input signal recursively, so that the overall amplitude envelope of the output signal replicates the wave pattern of the input signal. The nested inductor arrays produce multiple levels of recursive modulation, so that the output signal incorporates multiple integrated self-similar harmonic layers, such that the phasing of the various layers are locked in by the analog waveform of the output signal itself. As a result, the spatial “depth” and temporal “immediacy” of the original analog recording is restored and can be encoded in digital format.

A commercial album of analog audio recordings, having multiple tracks, is identified. An analog recording of the album is played to produce an analog audio input signal. The audio output signal is digitally sampled to produce digitized segments. One or more track-titles are obtained (1902) from a remote audio finger-printing service for each digitized segment to provide track-titles. For each obtained track-title, each album-title is requested (1905) upon which the obtained track-title appears, to provide candidate albums. A score is generated (1905) for each provided candidate album based on the number of obtained track-titles that appear on a provided candidate album in the correct order. An album is identified by comparing (2209) these scores.

A second circuit(for instance a video decoder), at least connectable(for instance through a path switch)to the first output, can digitize the first baseband analog video signal and process and output a corresponding digital stream on a second output. The second output is in turn at least connectable(for instance through a digital switch)to a third circuit(for instance a video encoder)generating on a third output a second baseband analogvideo signal on the basis of the digital stream.
