Abstract: This disclosure is directed to devices, systems, and techniques for monitoring one or more patient conditions. For example, a system includes a memory and processing circuitry communicatively coupled to the memory. The processing circuitry is configured to receive, from a sensor, an electrical representation of a first optical signal and control a pressure device to apply pressure to the patient in order to affect one or more physiological parameters proximate to the sensor. Additionally, the processing circuitry is configured to receive, from the sensor after applying the pressure to the patient, an electrical representation of a second optical signal; and determine, based on the electrical representation of the first optical signal and the electrical representation of the second optical signal, one or more patient conditions.

Abstract: A light sensing device includes a first light source configured to emit light within a first wavelength range, a second light source configured to emit light within a second wavelength range, detector circuitry, a first photodetector in the detector circuitry configured to detect the light within the first wavelength range, and a second photodetector in the detector circuitry configured to detect the light within the second wavelength range. The first photodetector and the second photodetector are in parallel in the detector circuitry such that the detector circuitry sums electrical signals outputted by the first photodetector and the second photodetector.

Abstract: A method for acquiring, externally or internally, for utility purposes a subject's anatomical heart-sound information including (a) for a selected time period, applying continuous, near-sensor-mechanical-resonance, vibratory stimulation to an acoustic sensor placed on or within the subject's anatomy, and (b) during that time period, detecting, as direct indications of heart sounds, changes in the sensor's physical resonance properties produced by heart sounds arriving at the sensor.

Abstract: A computer-network-based methodology and system for enhancing user control over the storage and transfer of user-personal information data in a network setting which includes both control-distant and control-near, information-data storage sites, and where user-personal information data which the user wishes to move may be held in the control-distant storage site. The methodology, implemented by the associated system, features enabling direct, user-control-access to any user-personal information data which is held in the control-distant storage site, and following such enabling, and under direct user-permitted command, promoting user-command transfer of at least a selected portion of the user-personal information data which is held in the control-distant storage site from the control-distant storage site to the control-near storage site.

Abstract: A method and a system for monitoring and characterizing a person's heart condition for various medically related purposes. The method includes the steps of (a) acquiring a selected person's acoustic heart signature, (b) acquiring, substantially simultaneously, that same person's electrical heart signature, (c) choosing elements of determined interest from these two acquired signatures and selectively processing and inter- and/or cross-relating such elements, and (d) employing the results of the relating step to create a heart-condition fingerprint useful in the characterization of that person's heart condition.

Abstract: A combined audio and electrical anatomy-signal sensor which is designed to collect, essentially from a selected, common anatomical site, related audio and electrical anatomical signals, such as heart-produced signals. The sensor includes a unique body structure which is designed to function both as a part of the audio-information gathering structure, and as a part of electrical electrode structure for gathering electrical signals. Chamber space is provided within this body for receiving and containing desired electrical circuitry, in the form of circuit-board-supported electrical components, which may be designed to perform any one of a number of different functions relative to signal gathering and transferring at and from an anatomical site.

Abstract: Algorithms for detecting, sizing and locating old myocardial infarcts by evaluating particular ECG lead data derived from selected ECG leads, where that particular data is presented hierarchically for review and confirmation, and includes selected voltage-amplitude ratios of R/Q and R/S. For a given human subject, the specific hierarchical pattern of lead data to be examined is selected on the basis of predetermined personal and demographic data, and completely in light of various, well-known, so-called confounders and excluders.

Abstract: A releasably interconnectible, signal-communicative interface between an anatomical signal sensor and an associated receiving coupler-adapter. Through complementary male and female interconnection structures, this interface is designed to accommodate both a mechanical, and an electrical, releasably locked cross-connection between such a sensor and a coupler-adapter. Spring-biased cam-interengaging interface components, including a cam surface on the sensor, and a pair of relatively moveable opposed clamping arms on the coupler-adapter operate, during the act of connection, to draw a sensor projection into a connected condition within a socket provided in the coupler-adapter. A springy, electrically conductive component in the adapter plays both mechanical and electrical roles in relation to operation of the interface.
