Appl. No.:

11/580269

Assignee:

Sensory, Inc., a California Corporation - Sunnyvale CA

International Classification:

G05B 19/00

US Classification:

340005520, 382115000, 704270000, 070277000

Abstract:

In one embodiment the present invention includes a biometric information recognizer and a shape memory material. The biometric information recognizer recognizes biometric information (such as speech) and signals the shape memory material with a current. The current causes the shape memory material to change shape, thereby reconfiguring a mechanical device. Such mechanical device may include a lock. In such manner, the lock may be isolated from external tampering (such as physical stressing) yet receptive to biometric information for controlling access.

Appl. No.:

16/682850

Inventors:

- Mountain View CA, US
Jeffrey Rogers - Sunnyvale CA, US

International Classification:

H04B 10/116
B60Q 1/50

Abstract:

In one example, a device includes a first platform having a first side and a second platform having a second side that overlaps the first side. The device also includes an actuator that rotates the first platform relative to the second platform. The device also includes a plurality of light sources mounted to the first platform in a substantially circular arrangement around the axis of rotation of the first platform. The plurality of light sources emit a plurality of light beams such that respective adjacent light beams intersect at least at a predetermined distance to the first side. The first side remains at least at the predetermined distance to the second side in response to the actuator rotating the first platform. The device also includes a light detector mounted to the second platform and positioned to at least partially overlap at least one of the plurality of light beams.

Abstract:

This document describes ways in which to alter physiological signals to address corrupt, noisy, or otherwise faulty data. By so doing, accuracy and robustness in sensing and assessing a patient's cardiovascular health can be improved. These improved assessments permit better measures of health, such as relevant hemodynamics understood by heart rates, heart rate variability, cardiac arrhythmias, blood pressures, pulse-wave velocities, arterial stiffness, cardiac valve timing, thoracic fluids, ballistocardiogram force, photo-plethysmograms, blood oxygenation, and pressure-volume loops.

A61B 5/0205

Abstract:

This document describes optical central venous pressure measurement. To determine the central venous pressure (CVP) of a person optically, video of a right side of the person's neck is captured. By way of example, a medical professional records a video of the right side of the person's neck using a smartphone. The right side of the person's neck is captured because it is where the person's external and internal jugular veins are located and pulsatile motions that are usable to measure CVP occur in those veins. The video is then processed according to video motion amplification techniques to generate a reconstructed video of the right side of the person's neck. In the reconstructed video, the pulsatile motion of the person's venous system that occurs at the right side of their neck is visually amplified. Using the reconstructed video, measurements are made of a distance between a peak of the visually-amplified pulsatile motion and an anatomical feature of the person. The measured distance between the peak of the visually-amplified pulsatile motion and the anatomical feature is used to determine CVP of the person. These techniques enable CVP to be determined without relying on estimates made by medical professionals.

Abstract:

This document describes assessing cardiovascular function using an optical sensor, such as through sensing relevant hemodynamics understood by pulse transit times, blood pressures, pulse-wave velocities, and, in more breadth, ballistocardiograms and pressure-volume loops. The techniques disclosed in this document use various optical sensors to sense hemodynamics, such as skin color and skin and other organ displacement. These optical sensors require little if any risk to the patient and are simple and easy for the patient to use.

International Classification:

G06F 19/00

Abstract:

This document describes techniques and apparatuses enabling determination of health state trends for a consistent patient situation. Various noninvasive health monitors can be used to sense a patient's situation and health states, including disease progression, at those states. These noninvasive health monitors may also act passively and in a patient's normal course of life, which enhances many patient's desire to submit to monitoring, as well as increase consistency of use, as in many cases the patient does little or nothing to cause his or her health monitoring and health-trend determination. With health states determined for a consistent patient situation, more accurate and more robust health trends can be determined.

Abstract:

This document describes synchronizing cardiovascular sensors for cardiovascular monitoring, such as through sensing relevant hemodynamics understood by pulse transit times, blood pressures, pulse-wave velocities, and, in more breadth, electrical conduction properties, cardiac rhythms, thoracic impedance, ballistocardiograms and pressure-volume loops. The techniques disclosed in this document use various cardiovascular sensors to sense hemodynamics, such as skin color and skin and other organ displacement. These cardiovascular sensors require little if any risk to the patient and are simple and easy for the patient to use.
