  • Publication number: 20070156030
    Abstract: The present invention is directed to methods for analyzing electrical signals generated by biological tissues, such as muscles (e.g., cardiac or skeletal muscle) and tissue within the nervous system (e.g., neurons within the central and peripheral nervous systems). The tissue may be a patient's own, or it may have been transplanted into the patient from a donor organism or from a tissue or cell culture. The result of the analysis indicates the condition of the tissue, and results obtained over time can alert a patient or health care professional to changes in that condition.

  • Publication number: 20050234360
    Abstract: The present invention provides systems, methods and computer program products for monitoring a heart. According to one embodiment, the system includes an implantable registering unit. The registering unit comprises a first controller structured to register an electrical signal from the heart. The system includes a second controller in operable communication with the first controller. The second controller comprises a data repository structured to receive data corresponding to the registered electrical signal and being structured to store the data. The data repository stores data corresponding to a baseline electrical signal of the heart. The second controller is structured to receive the data from the first controller corresponding to the registered electrical signal and to compare the registered electrical signal to the baseline electrical signal to determine whether the heart is functioning properly.

  • Patent number: 6797072
    Abstract: A process for restoring magnetic recording tape damaged by “Sticky Shed” syndrome cleans magnetic tapes of the Backcoating which is causing their eventual degradation and destruction. The Backcoating is first removed in a multi-step process. A liquid cleaner, such as isopropyl alcohol, is applied to the Backcoating to dissolve it from and clean it off the Mylar Base. Before the liquid cleaner is applied, steps are taken to prevent the cleaner fluid from getting onto the Oxide side of the tape. The chemical cleaning is done as quickly as possible. The second step is to dry clean the Base surface of the tape to remove the remaining solvent and the debris of any remaining Backcoating. Then, the Oxide side of the tape is given a dry, non-chemical cleaning to remove the residue of contamination of the Backcoating which was deposited on the Oxide side of the tape as the result of physical contact with the Backcoating from the storage on the reel of tape.

  • Publication number: 20030219107
    Abstract: Methods and apparatus for preliminary communication identification and caller ID text messaging is disclosed. The systems receive text entry from a caller for a short text message to be sent in conjunction with the incoming call signal. The text message is updated between rings. The system is suitable for communicating the text message of the received incoming signal without indicating reception of the received signal to the caller.

  • Publication number: 20020021838
    Abstract: A system and method for examining a string of symbols and identifying portions of the string which match a predetermined pattern using adaptively weighted, partitioned context edit distances. A pattern is partitioned into context and value components, and candidate matches for each of the components is identified by calculating an edit distance between that component and each potentially matching set (sub-string) of symbols within the string. One or more candidate matches having the lowest edit distances are selected as matches for the pattern. The weighting of each of the component matches may be adapted to optimize the pattern matching and, in one embodiment, the context components may be heavily weighted to obtain matches of a value for which the corresponding pattern is not well defined. In one embodiment, an edit distance matrix is evaluated for each of a prefix component, a value component and a suffix component of a pattern.

  • Patent number: 5885213
    Abstract: The present invention provides a method and apparatus for adapting to noise sources affecting a pulse oximeter. Various available frequencies are evaluated to determine their respective noise levels and one is selected to act as the operating demultiplexer frequency. During normal operation of the pulse oximeter, the various available demultiplexer frequencies are periodically scanned to determine which has the lowest associated noise. The noise level associated with the operating frequency is used to determine the signal-to-noise ratio of the pulse oximeter signals and thereby qualify certain signals from the pulse oximeter. Those pulses associated with a signal-to-noise ratio below a predetermined threshold are rejected and excluded from use in calculating blood oxygen saturation.

  • Patent number: 5881490
    Abstract: A leader wire made from a more flexible 7.times.19 stainless steel cable rather than the standard 7.times.7 cable leader wire includes a loop at one end and a swivel at the other. A first hook is attached to the loop at the end of the leader. Intermediate the two ends is a second hook which is movable along the length of the leader. A length of thin copper wire is twisted around the leader at a position between the second hook and the swivel and is movable therealong. The copper wire can be held in place, however, by a small sleeve that passes over the same. The wire is utilized to hold the mouth of the bait fish closed and to hold the bait fish in place by wrapping the wire around the same.
