System and methods for recognizing sound and music signals in high noise and distortion

A method for recognizing an audio sample locates an audio file that most closely matches the audio sample from a database indexing a large set of original recordings. Each indexed audio file is represented in the database index by a set of landmark timepoints and associated fingerprints. Landmarks occur at reproducible locations within the file, while fingerprints represent features of the signal at or near the landmark timepoints. To perform recognition, landmarks and fingerprints are computed for the unknown sample and used to retrieve matching fingerprints from the database. For each file containing matching fingerprints, the landmarks are compared with landmarks of the sample at which the same fingerprints were computed. If a large number of corresponding landmarks are linearly related, i.e., if equivalent fingerprints of the sample and retrieved file have the same time evolution, then the file is identified with the sample. The method can be used for any type of sound or music, and is particularly effective for audio signals subject to linear and nonlinear distortion such as background noise, compression artifacts, or transmission dropouts. The sample can be identified in a time proportional to the logarithm of the number of entries in the database; given sufficient computational power, recognition can be performed in nearly real time as the sound is being sampled.

Secure, networked and wireless access, storage and retrival system and method utilizing tags and modular nodes

A system apparatus and method of monitoring in a secured fashion the access, storage and retrieval of information, using a networked modular wireless device. The system may include a network of wireless, Wi-Fi devices (or any other wireless communication mechanism such as GPRS, GSM, iDen), or Nodes, each one of them possibly controlling the access to a medically sensitive object, such as a drawer (or cabinet) or to a medical device, or to another information source, item of equipment, drug, etc as well as tracking via RFid readers the access to the records or information contained in it. In the case of a physical file, each file has an RFid tag on it that is being read when removed or returned to the cabinet. Access to the cabinet and physical records, or to the medical device is monitored by reading the RFiD identity card of personnel accessing the cabinet or medical devices. In addition to controlling the access to the cabinet or medical device by controlling the cabinet lock (or in the case of a small medical device, the lock of an IV, injection device, specimen collection unit, or of a large medical device such as a defibrillator), the node can alert electronically by sending a message to the controlling unit, or by sending a physical alert (such as an alarm signal), when unauthorized personnel is attempting to access the cabinet, the files or devices. The system is useful in the context of monitoring the information contained in physical files, such as medical information, and can be used for access to medical devices, in order to better monitor the authorization rights of personnel participating in processes such as drug delivery or specimen collection. A control unit monitors activity at a plurality of nodes, and assists in storing the list of authorized personnel and files, and can store electronically captured information regarding the physical files (for example, the reason for accessing the file and reasons for changes in it) or medical device. The system can communicate with other information management systems.

Controlled electroporation and mass transfer across cell membranes

Electroporation is performed in a controlled manner in either individual or multiple biological cells or biological tissue by monitoring the electrical impedance, defined herein as the ratio of current to voltage in the electroporation cell. The impedance detects the onset of electroporation in the biological cell(s), and this information is used to control the intensity and duration of the voltage to assure that electroporation has occurred without destroying the cell(s). This is applicable to electroporation in general. In addition, a particular method and apparatus are disclosed in which electroporation and / or mass transfer across a cell membrane are accomplished by securing a cell across an opening in a barrier between two chambers such that the cell closes the opening. The barrier is either electrically insulating, impermeable to the solute, or both, depending on whether pore formation, diffusive transport of the solute across the membrane, or both are sought. Electroporation is achieved by applying a voltage between the two chambers, and diffusive transport is achieved either by a difference in solute concentration between the liquids surrounding the cell and the cell interior or by a differential in concentration between the two chambers themselves. Electric current and diffusive transport are restricted to a flow path that passes through the opening.

Relief object image generator

A device for imaging a relief object without illuminating a platen is disclosed. The device includes a single electrode electroluminescent device, which may be inorganic or organic, and a current source. The current source is coupled to the single electrode of the electroluminescent device and to the relief object to be imaged. The valleys and ridges of the relief object couple current to the electroluminescent device at different magnitudes which causes the electroluminescent device to generate light at different intensities that correspond to the ridges and valleys of the relief object. The generated light forms an image of the relief object which may be focused by optical elements onto a sensor array for capture and image processing. In another embodiment of the invention, a one-to-one sensor array is located proximate the electroluminescent device to capture the image. In an embodiment of the invention which insulates the relief object from current, the electroluminescent device is covered with a variable resistance layer and the variable resistance layer is covered with a flexible electrode. One lead from the current source is coupled to the flexible electrode and another lead is coupled to the single electrode. When a relief object is brought in contact with the flexible electrode, a localized pressures generated by the ridges of the relief object form conductive paths through the variable resistance layer which are lower in electrical resistance than those formed by pressure in the areas adjacent the valleys of the relief object. The different magnitudes of current delivered through the conductive paths to the electroluminescent device cause the electroluminescent device to generate an image of the relief object without exposing the relief object to electrical current.
