摘要:
An ECG monitoring device comprises an integral handheld device including a ECG electronic module and an electrode patch having a plurality of electrodes which contact a subject by conductive hydrogel. A release liner covers and protects the hydrogel prior to use and is removed to expose the hydrogel. A second release liner is removed to expose a pressure sensitive adhesive by means of which the device is attached to a subject. The first and second release liners may be parts of a single release liner layer. After use the electrode patch is disposable and the ECG electronic module is detached from the patch for reuse.

摘要:
A package for increasing shelf life of electrodes packaged therein. A first package within which one or more gel-containing electrode pads are sealed. In addition, at least one moisture source is sealed within the package.
摘要:
A sealed package for housing an electrical component. The package includes at least two package portions. Determining elements within the sealed package determine at least one parameter including at least one ambient condition within the package and/or an electrical function parameter of the component. An indicator is operatively connected to the determining elements to indicate the functionality of the component within the sealed package.
摘要:
An electrode includes a conductive adhesive layer and a conductive foil layer having a void therein. One such electrode may be mounted in conjunction with another electrode upon a release liner having one or more openings therein to facilitate electrical signal exchange between electrodes. A release liner may include a moisture permeable and/or moisture absorbent membrane. A release liner may alternatively include a conductive backing layer. A release liner may also include an insulating swatch covering an opening. A release liner may be implemented as a foldable sheet, such that multiple electrodes may be mounted upon the same side of the foldable sheet. A medical device to which the mounted electrodes are coupled may characterize the electrical path between the electrodes. The medical device may perform a variety of electrical measurements, including real and/or complex impedance measurements. Based upon one or more measurements, the medical device may provide an indication of electrode condition, fitness for use, and/or an estimated remaining lifetime. An electrode condition indicator, which may form a portion of the medical device, may generate, present, or display electrode condition and/or estimated remaining lifetime information via a visual metaphor, such as a fuel gauge.

摘要:
An apparatus for delivering defibrillation therapy to a patient. Specifically, an external defibrillators or automatic or semi-automatic external defibrillator (AEDs) is described. The defibrillator is automatically activated or inactivated by, for example, inserting or removing an object, such as a plug or a pin, into a receptacle within the defibrillator housing.
摘要:
A computer receives image data from a star-shaped optical target in the object plane and calculates angle-dependent boundary sharpness. The horizontal, x-direction, amplitude derivative and the vertical, y-direction, amplitude derivative are computed over a portion of each star pattern image from a Z panning sequence. A microscope slide stage, carrying the target, is moved vertically from a level just below where the target is in focus to a level just above where the target is in focus. For each small increment of vertical motion, Z panning, an image of the star pattern is captured for analysis. Computations are performed on the differentiated images to search for evidence of elongation of the point spread function and variation with stage Z position of the angle of long axis of such an out-of-round point spread function. The presence of a distorted point spread function that varies along the optical axis indicates astigmatism.

A defibrillator system including a defibrillator and at least one indicator including at least one visual indicator and/or at least one audible indicator connected to the defibrillator for generating an indication of a functional status of the defibrillator periodically and/or on command by a user.
摘要:
Accurately measuring and controlling the system transfer function of an imaging system, by eliminating interference from aliases. An image is captured of an image primitive with a uniaxial pattern, oriented at an angle to the primary axes of a sampling array. In order to accurately measure the system transfer function, a two-dimensional frequency representation is computed. The aliased components of the representation are separated from the unaliased components by translation in frequency along the axis perpendicular to the axis of the image primitive. Accurate measurement of the system transfer function makes it possible to accurately control the system transfer function.
