  • Publication number: 20190029515
    Abstract: An ophthalmological analysis method measures an intraocular pressure in an eye using an analysis system. The analysis system includes an actuation device, with which a cornea of the eye is deformed contactlessly. The actuation device applies a puff of air to the eye to deform the cornea. A monitoring system monitors the deformation of the cornea and records sectional images of the undeformed and deformed cornea. An analysis device derives an intraocular pressure from the sectional images of the cornea, wherein the recorded sectional images of the deformed cornea are corrected relative to a recorded sectional image of the undeformed cornea, the intraocular pressure being derived under consideration of the correction.

    Abstract: An ophthalmic technician is present with a patient in an exam room to operate eye examination equipment and transmit patient information to remote location. At that remote location, a skilled technician is present to provide the necessary optical care, and may operate the phoropter from the remote location. Using video and/or teleconferencing equipment and a phoropter located in the patient examination room along with management software, the system works to determine the final optical prescription for the patient. That information, coupled with findings from other devices which are integrated with the management software, and that the patient uses locally, are reviewed by a remote-based optometrist or ophthalmologist.

    Abstract: Devices and techniques for magnetic detection of myocardial forces are generally described. In some examples, cardiac tissue may be cultured such that the cardiac tissue adheres to a first post and a second post. In further examples, a magnetometer may detect a change in a magnetic field resulting from a deflection of the first post in a first direction from a first position to a second position. In some other examples a signal corresponding to the change in the magnetic field may be generated. In still other examples, frequencies of the signal outside of a first frequency range may be excluded to produce a filtered signal. In various examples, the first frequency range may include frequencies associated with beating of cardiac tissue. In still further examples, a force exerted by the cardiac tissue may be determined based at least in part on the filtered signal.

  • Publication number: 20190029551
    Abstract: An initial set of parameters for operating one or more detection tools is automatically derived and subsequently adjusted so that each detection tool is more or less sensitive to signal characteristics in a region of interest. Detection tool(s) may be applied to physiological signals sensed from a patient (such as EEG signals) and may be configured to run in an implanted medical device that is programmable with the parameters to look for rhythmic activity, spiking, and power changes in the sensed signals, etc. A detection tool may be selected and parameter values derived in a logical sequence and/or in pairs based on a graphical representation of an activity type which may be selected by a user, for example, by clicking and dragging on the graphic via a GUI. Displayed simulations allow a user to assess what will be detected with a derived parameter set and then to adjust the sensitivity of the set or start over as desired.

    Abstract: An apparatus comprises an arrhythmia detection circuit configured to: receive a cardiac signal representative of cardiac activity of a subject; apply a first arrhythmia detection criteria to the received cardiac signal; apply, in response to the applied first arrhythmia detection criteria producing a positive indication of arrhythmia, a second arrhythmia detection criteria to the received cardiac signal, wherein the second arrhythmia detection criteria is more specific to detection of arrhythmia than the first detection criteria; detect, in response to the applied first and second arrhythmia detection criteria, a sensing event indicating one or both of the first and second arrhythmia detection criteria are susceptible to false indications of arrhythmia; and adjust, in response to a detected sensing event, sensitivity or specificity of one or both of the first and second arrhythmia detection criteria.

  • Publication number: 20190029553
    Abstract: An ECG system measures and annotates a subdivision of the P wave of the ECG waveform from harmonic waveforms. Electrical impulses are received from a beating heart. The electrical impulses are converted to an ECG waveform. The ECG waveform is converted to a frequency domain waveform, which, in turn, is separated into two or more different frequency domain waveforms, which, in turn, are converted into a plurality of time domain cardiac electrophysiological subwaveforms and discontinuity points between these subwaveforms. The plurality of subwaveforms and discontinuity points are compared to a database of subwaveforms and discontinuity points for normal and abnormal patients. Starting and ending discontinuity points are identified for a subdivision of the P wave of the ECG waveform and an APD is calculated for the subdivision. The ECG waveform is displayed along with a location of the P wave subdivision on the ECG waveform and the calculated APD.

  • Publication number: 20190029555
    Abstract: As one example, a fluid monitoring apparatus includes a dielectric microsensor that includes a capacitive sensing structure integrated into a microfluidic channel. The microfluidic channel includes a fluid input to receive a sample volume of a sample under test (SUT). A transmitter provides an input radio frequency (RF) signal to an RF input of the microsensor. A receiver receives an output RF signal from the microsensor. A computing device computes dielectric permittivity values of the SUT that vary over a time interval based on the output RF signal. The computing device may determine at least one permittivity parameter based on the computed dielectric permittivity values over at least a portion of the time interval.

    Abstract: Systems and methods are provided for detecting and analyzing changes in a body. A system includes an electric field generator, an external sensor device, a quadrature demodulator, and a controller. The electric field generator is configured to generate an electric field that associates with a body. The external sensor device sends information to the electric field generator and is configured to detect a physical change in the body in the electric field, where the physical change causes a frequency change of the electric field. The quadrature demodulator receives the electric field from the electric field generator and is configured to detect the frequency change of the electric field and to produce a detected response. The controller, coupled to the electric field generator, is configured to output a frequency control signal to the electric field generator and to modify the frequency of the electric field by adjusting the frequency control signal.

    Abstract: An image registration system using a subject-specific tracker includes: a photographing unit for obtaining a scanning image; a fabricated tracker based on anatomical data of the user including tracking markers for defining relative positions; a recognizing unit configured to recognize positions of the tracking markers and an image registration unit configured to register the scanning image based on the positions of the tracking markers. According to the system, a body part of the user and a scanning image may be automatically registered without a conventional image registration process such as an attachment of a fiducial marker and a confirmation of the fiducial marker position using CT/MRI imaging. Accordingly, it is possible to minimize an error caused by human, ensure precise registration, allow trackers to be attached or detached as necessary during surgery operation, and keep the accuracy of registration after the trackers are attached or detached.
