Abstract: A vision screening device captures image(s) of reflected radiation from light source(s) and uses the images to determine a cornea curvature. The light source(s) may comprise infrared LEDs and be configured in a predetermined pattern. Based on the cornea curvature, an axial length is determined and/or a prescription for a patient is determined. Other characteristics of the patient may be used to determine axial length. Based on the axial length, a recommendation for the patient is generated and displayed.

Abstract: Devices, systems, and methods for High Frequency Chest Wall Oscillation therapy can include a therapy garment including a covering garment for dressing on a patient's torso, the covering garment including a bladder pocket defined between inward and outward layers, and a fluid bladder arranged within the bladder pocket. The fluid bladder can define a pressurizable chamber adapted to receive pressurized fluid to provide force of high frequency pressure oscillation to a patient's chest wall. The pressurizable chamber can be formed to define an outer profile shaped to correspond closely with the patient's rib cage profile to reduce transfer of force of high frequency chest oscillation to the patient's torso outside of the patient's rib cage profile.

Abstract: A system includes system housing, an eccentric radiation source, and a radiation sensor. The radiation produced by the eccentric radiation source can be collected by the radiation sensor to generate images of retinas for a patient. The system also includes a vision screening device connected with the eccentric radiation source and the radiation sensor via the system house that can control and synchronize actions for the eccentric radiation source and the radiation sensor. The vision screening device further analyzes the images generated by the radiation sensor via neural network algorithms to determine spherical error slopes, refractive errors, and recommendations for the patient.

Abstract: A patient monitoring system includes a microphone that collects audio data from a patient. The audio data is used to generate audio characteristics for categorization of the audio data and analysis of the audio data to determine a patient health status. The audio characteristics and the patient health status are tracked over time and utilized to monitor a respiratory condition of the patient. The system determines the patient health status based on a comparison of the audio characteristics with a database of audio characteristics associated with recorded health statuses of various patients. The system generates a report of the current patient health status based on the database of audio characteristics and associated health statuses.

Abstract: A dermal imaging system coordinates operation of an illumination unit, one or more lenses, and a camera to capture a sequence of images of an area of interest on a skin surface. The system automatically tags each image in the sequence of images. The tag for each image identifies a light source, an illumination angle, and a filter selected for capturing the image. The system automatically selects at least one image from the sequence of images, and analyzes the selected image from the sequence of images to provide a recommended skin disease diagnosis.

Abstract: A system for determining refractive error of an eye includes at least two light-emitting diodes (LEDs), an image capture component, and a processor configured to execute instructions to perform operations associated with a vision screening exam. For example, the processor causes each of the two LEDs to emit light to form a combined light that is output to a pupil. The processor causes the image capture component to capture an image depicting the eye while the combined light is being output. The processor determines an eccentricity at a time that the image was captured, corresponding to a simulated source location of the combined light caused by combining the light from the two LEDs. The processor determines an amount of light reflected on the pupil in the image, and a refractive error of the eye based on the eccentricity and the amount of light reflected on the pupil in the image.

Abstract: One apparatus includes a notch filter that has a state observer unit and a parameter adaptation unit. The state observer unit is configured to receive a sampled noisy electrical signal and a sampled filtered electrical signal, the state observer unit having an estimated noise signal output, the estimated noise signal output carrying an estimated noise signal to be subtracted from the sampled noisy electrical signal, resulting in the filtered electrical signal. The parameter adaptation unit is configured to receive the estimated noise signal and an error signal from the state observer unit. The parameter adaptation unit is also configured to determine, based on the estimated noise signal and the error signal, an updated estimated noise frequency, thereby causing the state observer unit to generate an updated estimated noise signal to be provided on the estimated noise signal output.
