Abstract: Disclosed herein are computer-implemented methods and systems for assessing a risk value of a target patient, the method comprising: receiving at a server, via a connection mechanism, target patient data; estimating at the server, using one or more risk assessment models, one or more risk values associated with the target patient data. Target patient data may comprise historical data, patient population-level data, and real-time data. Risk assessment models may comprise one or more of: historical data risk assessment models, real-time data risk assessment models, or a combined risk assessment model. Methods for training such models are described. Systems and methods as described preferably enable continuous patient monitoring based on a patient's historical data and continuous, real-time physiological data.

Abstract: The dental chair attachment for supporting wheelchairs attaches to the back of a dental chair and reclines a wheelchair when the dental chair is reclined. The wheels of the wheelchair are rolled onto wheel ramps on opposing sides of a back support. Two upper clamps attach the dental chair attachment to the top of the dental chair, and two lower clamps attach the wheelchair to the dental chair attachment. When reclining the dental chair, wheels on the bottom of the back support allow the dental chair attachment to recline simultaneously with the chair by rolling in a direction opposite the dental chair.

Abstract: Provided is a geometric correction apparatus and method based on a recursive Bezier patch sub-division. A geometric correction method may include: receiving, from a camera, a first image that is obtained by photographing a black screen that is projected by a projector onto a projection surface; receiving, from the camera, a second image that is obtained by photographing a predetermined pattern that is projected by the projector onto the projection screen; generating a third image by subtracting the first image from the second image; and performing geometric correction with respect to the predetermined pattern to correct a distortion between the predetermined pattern and the third image.
