  • Publication number: 20180116505
    Abstract: An objective phoropter utilizing an illuminated keratometric object projecting its illumination onto the subject's cornea, and imaging the reflection therefrom in an imaging camera. Image processing of these images is used to improve the focusing and centering of the cornea subject's eyes. Once the correctly focused position of the eyes is obtained relative to the keratometer object, an accurate longitudinal position of the eyes relative to the lens wheel assemblies can also be achieved. This results in more accurate prescription generation than in prior art systems where the eyes may not be accurately positioned relative to the lens wheels. Additionally, the lens combinations of the entire phoropter wheel can be calibrated using an artificial eye having adjustable levels of aberration. Each lens combination is adjusted to supposedly correct a selected aberration level, and any residual aberration measured represents the correction to be applied to that lens combination.

The HMD exposes sensitive data to the user who wears the HMD. The CAM takes thermal measurements of a region of interest (THROI) on the user's face while the user is exposed to the sensitive data. And the computer detects, based on certain THROI taken while the user was exposed to certain sensitive data, whether the user experienced the irregular physiological response while being exposed to the certain sensitive data.

  • Publication number: 20180116529
    Abstract: A biopsy needle surrounded by a peel away sheath chemically impregnated with a blood detection composition enabling a user (e.g., a surgeon) to accurately and timely determine the existence of a blood pooling or hematoma when passing an implantable (e.g., deep brain stimulation probes) or non-implantable (e.g., biopsy needle) device into a region of the subject's body (e.g., a brain) to gather tissue for further analysis. A biopsy needle may be provided wherein the needle is tightly surrounded by a peel-away sheath that is chemically impregnated with a blood detection composition. The surgeon may insert the biopsy needle into the subject and peel away the chemically impregnated sheath in order to assess whether or not a blood pooling or hematoma exists, and act immediately to address the blood pooling or hematoma.

  • Publication number: 20180116530
    Abstract: An apparatus includes a wearable sensor structure that includes multiple individual sensor units placed in a row. Each individual sensor unit includes a first portion to contact a surface of skin under which arteries and/or veins are to be located, and a second portion that contacts the first portion and is configured to have a capacitance. The first and second portions are configured to create a capacitance change in response to a squeezing or bending between the first portion and a fixed part of the second portion caused by a pulse pressure and release of the pulse pressure. The apparatus includes circuitry configured to measure waveforms for the individual sensor units. Each waveform captures the capacitance change for its corresponding individual sensor unit. The apparatus includes a wireless interface configured to transmit the waveforms. A computing system is also disclosed that analyzes the waveforms and can provide alerts based thereon.

  • Publication number: 20180116534
    Abstract: A system and method for blood pressure signal acquisition using a pressure sensor array. A solution is provided for a non-inflatable, non-invasive, continuous blood pressure waveform and blood pressure acquisition system. The system is operative to combine signals from various sensing elements where the less accurate sensor elements are calibrated utilizing the more accurate sensor elements. Blood pressure measurements are acquired using very sensitive pressure sensors that detect slight pressure changes through the skin, which are sampled and processed to yield a blood pressure signal, which is processed to yield actual systolic and diastolic continuous and or intermittent blood pressure readings. By sampling and detecting the signal in each of the sensors, the sensor that is best placed on the target artery is found and the signals from that sensor is used to weight the signals from other sensors based on signal quality.

    Abstract: A system and method of monitoring electrocardiogram (ECG) signals and detecting ischemic conditions. In particular, high-frequency components and low-frequency components are extracted from the monitored ECG signal. The high-frequency components are analyzed to detect reduced amplitude zones (RAZs), while the low-frequency components are utilized to detect premature ventricular contraction (PVC) beats. Potentially ischemic conditions are identified based on both RAZs and PVC beats detected.

The sense channel may be configured to process the sensor output signal and output a sense channel output signal. The sense channel may have an adjustable performance level, wherein for a higher performance level the sense channel consumes more power than for a lower performance level. A controller may be configured to adjust the performance level of the sense channel to achieve more performance and more power consumption when a higher degree of sense channel performance is desired and to achieve less performance and less power consumption when a higher degree of performance is not desired.
