Abstract
A system, software and method of streaming ECG/EKG data over Bluetooth low-energy interface.
Core Innovation
The invention provides a system and software protocol for streaming real-time ECG data over a Bluetooth Low-Energy (BLE) interface to BLE-enabled mobile computational devices. It uses at least one ECG data acquisition unit that communicates with the BLE-enabled mobile computational device so that ECG data may be transmitted to, processed by, analyzed by, stored on or re-transmitted from the BLE-enabled mobile device.
The document addresses the end-to-end BLE data/command flow between the acquisition unit and the mobile device, including server mode and client mode operation. ECG data can be transmitted in packetized/discrete transmission, buffered, and processed or stored, and the document further describes buffer and sequence counter management on the device and mobile client, together with data and command/status exchange for start capture and stop capture, periodic updates, and status requests and returns.
To support reliable streaming, the document describes encryption and decryption functionality and error handling for missing-sequence detection, including resending of data. It further describes device firmware and mobile client module functionality such as ECG reception handling, reception status handling, transmission command management, and data transmission buffering, along with disconnect and time out behavior. Overall, the protocol is described as optimized for reliable raw ECG streaming with optimized battery life.
Claims Coverage
The independent claims cover a BLE streaming system, a corresponding method, and a non-transitory software product executed on the BLE-enabled mobile computational device. Across these independent claims, the inventive features include providing an ECG data acquisition unit, a BLE-enabled mobile computational device, storage and processing means, and a software protocol enabling transmission of ECG data to and from the mobile device, including receiving, processing, and reporting.
Software protocol for transmitting raw real-time ECG data over BLE
A software protocol wherein the at least one ECG data acquisition unit communicates with the at least one BLE-enabled mobile computational device and ECG data is transmitted to, processed by, analyzed by, stored on or re-transmitted from the BLE-enabled mobile device.
ECG streaming system with acquisition, BLE mobile device, storage and processing
A system comprising at least one ECG data acquisition unit, at least one BLE-enabled mobile computational device, a means for the storage of the ECG data, and a means for processing the ECG data.
Non-transitory software product causing receive, process and report on acquired ECG data
A software product comprising a non-transitory computational device-readable medium in which program instructions are stored, which instructions, when read by the at least BLE-enabled mobile computational device, cause the BLE-enabled mobile computational device to receive ECG data, process the ECG data and produce a report on the acquired data.
Method of streaming real-time ECG data to mobile platforms over BLE with a software protocol
A method of streaming real-time ECG data to mobile platforms over a Bluetooth-Low-Energy interface comprising providing at least one ECG data acquisition unit, providing at least one BLE-enabled mobile computational device, providing a means for the storage of the ECG data, providing a means for processing the ECG data, and providing a software protocol wherein ECG data may be transmitted to, processed by, analyzed by, stored on or re-transmitted from the BLE-enabled mobile device.
The independent claims center on a BLE-enabled architecture that streams real-time ECG data using a software protocol between an ECG data acquisition unit and a BLE-enabled mobile computational device, with ECG data handling that includes transmitting to the mobile device, processing or analyzing, storing, and re-transmitting. A separate independent claim covers a non-transitory software product that causes the mobile device to receive, process, and produce a report, and another independent claim recasts the same architecture as a streaming method.
