  • Publication number: 20160033311
    Abstract: Techniques for enhanced microfluidic impedance spectroscopy include causing a core fluid to flow into a channel between two sheath flows of one or more sheath fluids different from the core fluid. Flow in the channel is laminar. A dielectric constant of a fluid constituting either sheath flow is much less than a dielectric constant of the core fluid. Electrical impedance is measured in the channel between at least a first pair of electrodes. In some embodiments, enhanced optical measurements include causing a core fluid to flow into a channel between two sheath flows of one or more sheath fluids different from the core fluid. An optical index of refraction of a fluid constituting either sheath flow is much less than an optical index of refraction of the core fluid. An optical property is measured in the channel.

  • Publication number: 20140221850
    Abstract: A monitor device and associated methodology are disclosed which provide a self contained, relatively small and continuously wearable package for the monitoring of heart related parameters, including ECG. The detection of heart related parameters is predicated on the location of inequipotential signals located within regions of the human body conventionally defined as equivalent for the purpose of detection of heart related electrical activity, such as on single limbs. Amplification, filtering and processing methods and apparatus are described in conjunction with analytical tools for beat detection and display.

  • Publication number: 20120245439
    Abstract: A physiological measuring system is disclosed that monitors certain physiological parameters of an individual through the use of a body-mounted sensing apparatus. The apparatus is particularly adapted for continuous wear. The system is also adaptable or applicable to calculating derivations of such parameters. A oxygen debt measuring embodiment is directed predicting an outcome in response to injury and illness. The technique allows for closed-loop resuscitation, early identification of illness and early corrective action.

  • Publication number: 20070208233
    Abstract: In some embodiments, a wearable physiologic monitor comprises a mixed analog and digital application-specific integrated circuit (ASIC) including signal conditioning circuitry, an A/D converter, a real-time clock, and digital control logic. The signal conditioning circuitry includes analog amplification circuitry, analog (continuous-time or switched capacitor) filtering circuitry before the A/D converter, and in some embodiments digital (DSP) filtering circuitry after the A/D converter. The monitor includes sensors such as electrocardiogram (ECG) electrodes, accelerometers, and a temperature sensor, some of which may be integrated on the ASIC. The digital control logic receives digital physiologic data sampled at different rates, assembles the data into physiologic data packets, time-stamps at least some of the packets, and periodically stores the packets in a digital memory. The monitor may include a disposable patch including the ASIC, and a reusable, removable digital memory such as flash memory card.

  • Publication number: 20070208262
    Abstract: In some embodiments, a wearable physiologic monitor comprises an application-specific integrated circuit (ASIC) including signal conditioning circuitry, a real-time clock, digital control logic, and mode-selection logic for setting an operating mode of the ASIC to a stand-alone mode or a peripheral mode. In the stand-alone mode, the digital control logic periodically stores data packets including multiple sensor data types in a digital memory such as a removable flash memory card. In the peripheral mode, the data packets are transmitted to a microcontroller for processing. The monitor includes sensors such as electrocardiogram (ECG) electrodes, accelerometers, and a temperature sensor, some of which may be integrated on the ASIC. The same basic chip design may be used in the stand-alone mode in disposable patches, and in the peripheral mode in bedside devices. The operating mode may be chosen at monitor manufacture, by connecting input pins to mode-selection logic levels.

  • Publication number: 20070208232
    Abstract: According to one aspect, physiologic monitor and/or firmware piracy are reduced by initializing physiologic monitors in the field, e.g. in medical facilities or user homes, upon verifying user authorization. A physiologic monitor may include sensors such as electrocardiogram (ECG) electrodes, accelerometers, respiratory and/or fluid load impedance electrodes, and a temperature sensor. The monitor may be connected to an initialization console, which activates and configures the monitor by transferring an authorization code, firmware, a set of enabled sensors and sampling rates, a set of customized voice messages, and other parameters, and/or by programming a programmable logic array. The initialization console may be a computer situated in a doctor's office or user's home, programmed with initialization and analysis software, and capable of connecting to an authorization server at a time of use.
