Abstract: The present invention relates to a field of communication technology that provides a method, system and device of location authentication. The method comprises the following steps: the mobile device receives the signal marking the position information of the location base station sent by the location base station within the same region. The mobile device would obtain the position information of the location base station after analyzing the signal; the location base station would send the position information to the location authentication server to obtain the location authentication that it is in the same region with the location base station. Thus, this invention performs the location authentication of the mobile device staying in the same region with the location base station.

Abstract: Physiological monitoring can be provided through a lightweight wearable monitor that includes two components, a flexible extended wear electrode patch and a reusable monitor recorder that removably snaps into a receptacle on the electrode patch. The wearable monitor sits centrally (in the midline) on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline, with its unique narrow “hourglass”-like shape, significantly improves the ability of the wearable monitor to cutaneously sense cardiac electrical potential signals, particularly the P-wave and, to a lesser extent, the QRS interval signals indicating ventricular activity in the ECG waveforms.

Abstract: In one embodiment, ECG data collected during the long-term monitoring are compressed through a two-step compression algorithm executed by an electrocardiography monitor. Minimum amplitude signals may become indistinguishable from noise if overly inclusive encoding is employed in which voltage ranges are set too wide. The resulting ECG signal will appear “choppy” and uneven with an abrupt slope. The encoding used in the first stage of compression can be dynamically rescaled on-the-fly when the granularity of the encoding is too coarse. In a further embodiment, offloaded ECG signals are automatically gained as appropriate on a recording-by-recording basis to preserve the amplitude relationship between the signals. Raw decompressed ECG signals are filtered for noise content and any gaps in the signals are bridged. An appropriate signal gain is determined based on a statistical evaluation of peak-to-peak voltage (or other indicator) to land as many ECG waveforms within a desired range of display.

Abstract: Physiological monitoring can be provided through a wearable monitor that includes a flexible extended wear electrode patch and a removable reusable monitor recorder. The wearable monitor sits centrally on the patient's chest along the sternum, which significantly improves the ability to sense cutaneously cardiac electric signals, particularly those generated by the atrium. The electrode patch is shaped to fit comfortably and conformal to the contours of the chest approximately centered on the sternal midline. To counter the dislodgment due to compressional and torsional forces, non-irritating adhesive is provided on the underside, or contact, surface of the electrode patch, but only on the distal and proximal ends.

Abstract: Physiological monitoring can be provided through a wearable monitor that includes two components, a flexible extended wear electrode patch and a removable reusable monitor recorder. The wearable monitor sits centrally (in the midline) on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline (or immediately to either side of the sternum) benefits extended wear by removing the requirement that ECG electrodes be continually placed in the same spots on the skin throughout the monitoring period. Instead, the patient can place an electrode patch anywhere within the general region of the sternum. Power is provided through a battery provided on the electrode patch, which avoids having to open the monitor recorder's housing for battery replacement. The patch further includes sensors for monitoring patient's air flow and respiratory measures contemporaneously with the ECG monitoring.

Abstract: A remotely-interfaceable extended wear electrocardiography and physiological sensor monitor recorder is provided. A sealed housing forms on a bottom surface a cavity shaped to accommodate an upward projection of a battery compartment formed on a non-conductive receptacle of a disposable extended wear electrode patch and includes a set of electrical contacts that protrude from the bottom surface and are arranged in alignment with electrical pads provided on the non-conductive receptacle. Electronic circuitry is provided within the sealed housing and includes an externally-powered micro-controller operable to execute under micro programmable control. An electrocardiographic front end circuit is electrically interfaced to the micro-controller. A wireless transceiver electrically interfaces with the micro-controller and externally-powered flash memory is electrically interfaced with the micro-controller and operable to store samples of the electrocardiographic signals.

Abstract: An extended wear electrocardiography patch is provided. A flexible backing is formed of an elongated strip of stretchable spunlace material. A layer of stretchable adhesive is applied on at least a portion of a contact surface of the flexible backing, which defines a pair of openings on both ends. A non-stretchable circuit is axially affixed to an outward-facing surface of the flexible backing and has a pair of circuit traces. The flexible backing acts as a buffer between the non-stretchable circuit and the stretchable adhesive and prevents disadhesion of the flexible backing during bending. A pair of electrocardiographic electrodes are electrically coupled to each of the circuit traces. Conductive gel is provided in each of the openings and in electrical contact with the pair of electrocardiographic electrodes as the electrodes shift away from the openings in the flexible backing during the bending.

Abstract: A monitor recorder-implemented method for electrocardiography value encoding and compression is provided. A plurality of codes are maintained, each associated with an electrocardiography value range. A series of electrocardiography values is obtained. A serial accumulator is set to a predetermined value; each of the obtained electrocardiography values from the series of the obtained electrocardiography values is processed, including: performing a mathematical operation on that obtained electrocardiography value and the serial accumulator; identifying the code within the range associated with which a result of the mathematical operation falls; representing that obtained electrography value with the identified code; and adjusting the serial accumulator by a value derived from the range associated with the identified code. Each of the represented codes are into a sequence in a non-volatile memory.

The electrode patch is made from a type of stretchable spunlace fabric. To counter patient bending motions and prevent disadhesion of the electrode patch, the outward-facing aspect of the backing, to which a (non-stretchable) flexible circuit is fixedly attached, stretches at a different rate than the backing's skin-facing aspect, where a skin adhesive removably affixes the electrode patch to the skin.

Abstract: A wearable electrocardiography monitoring ensemble is provided, which includes a garment made of a compressible and elastomeric material. The garment is wearable about an upper region of the torso and further includes an internal structure forming a compressive bias circumferential to the torso. The ensemble also includes an electrode assembly provided on an inside surface of the garment on an underside of the internal structure. The electrode assembly has a pair of electrocardiography electrodes, a pair of terminated electrical connections that are each coupled to one of the electrocardiography electrodes, and a backing to which the electrocardiography electrodes are affixed.

The placement of the wearable monitor in a location at the sternal midline (or immediately to either side of the sternum) benefits extended wear by removing the requirement that ECG electrodes be continually placed in the same spots on the skin throughout the monitoring period. The wearable monitor can interoperate wirelessly with other physiology and activity sensors and mobile communications devices, to download monitoring data either in real-time or in batches. The monitor recorder can provide data or other information to, or receive data or information from, an interfacing physiology or activity sensor, or mobile communications devices for relay to a further device, such as a server, analysis, or other purpose.

Abstract: A method for efficiently encoding and compressing ECG data optimized for use in an ambulatory electrocardiography monitor is provided. ECG data is first encoded and compressed in a lossy process and further encoded and compressed in a lossless process. A compression ratio significantly higher than other Holter-type monitors is achieved. Requirements for storage space and power cell consumption are reduced, contributing to the long-term availability of the monitor.
