A device for gathering data has first and second electrodes. The first electrode is coupled to a surface of interest, and the second electrode is coupled to “everything else” or “the air”. The first electrode is shielded from the second, and from most sources of parasitic capacitance, by a shield that is driven by an active driver that drives the shield to track, and ideally to match, the instantaneous potential of the electrode. The second electrode is likewise shielded in a similar way from most sources of parasitic capacitance. These shields likewise help to limit the extent to which RFI from the device electronics couples with either of the electrodes. In this way the sensing device achieves a markedly better signal-to-noise ratio at frequency bands of interest.

A system and method for recording magnetic resonance images with reduced relaxation-related artifacts. The system and method improve the conventional methods for acquiring magnetic resonance images of in vivo tissue by augmenting the procedures for eliminating artifacts caused by motion with procedures for eliminating artifacts caused by spin of the magnetic resonance-active nuclei in the specimen of interest. One procedure to eliminate such spin inhomogeneities is to require a delay defined by the time N*T 1 , where N is a numerical value greater than or equal to 5 and T 1 is the characteristic time constant for decay of spins back to the equilibrium longitudinal state. Another procedure uses a value of N less than 5.

Ambulatory physiological monitoring with remote analysis

Номер: US20120259233A1
Автор: Eric K. Y. Chan, Harold Strandquist
Принадлежит: Individual

Applicants have disclosed a wireless method for remotely monitoring the physiological status of ambulatory patients by using at least one “cloud” server. Physiological data, including ECG data, is collected by a device worn by a patient and then wirelessly transmitted (e.g., via a cell phone) to the server(s). Remote processing of electrocardiograms (“ECG”) is achieved, in part, by data streaming packet lengths acquired over no less than 3 seconds—3 seconds is typically equivalent to about 3 cardiac cycles (heartbeats)—to provide the quickest response time by clinicians to try to save a heart patient's life. Other types of physiological data are monitored by the device, so medical help can be obtained when needed. In this manner, any sudden onset of vicissitudes in a patient's well being may be detected and transmitted to the care-giver and patient in near real-time.

A method of registering two or more localization systems utilizing unique coordinate frames A and B to a common coordinate frames includes measuring position information for one or more reference locations r in each coordinate frame (e.g., A r and B r ). For each reference location, a fiducial grouping is created from the respective position measurements (e.g., (A r , B r )). The fiducial groupings are used to generate a mapping functionfthat transforms position measurements expressed relative to the second coordinate frame B to the first coordinate frame A. The mapping function f is defined such that a distance between f(B r ) and A r is about zero for each reference location r. Each localization system may also measure position information for a respective fixed reference localization element. Divergence between these fixed reference localization elements in the common coordinate system may be used to monitor, signal, and correct for anomalies such as dislodgement and drift.
