Abstract: A wellness diagnostic platform installed on a vehicle to identify potential passengers with evident symptoms of a contagious illness is described. The wellness diagnostic platform includes a wellness monitoring unit and a boarding confirmation unit. The wellness monitoring unit includes a camera and/or one or more thermal sensors. The camera may capture physical characteristics of the potential passenger to determine health and the thermal sensors can measure a temperature of the potential passenger prior to boarding the vehicle. The boarding confirmation unit is configured to receive at least a display object identifying a diagnostic result computed by the wellness monitoring unit that the potential passenger is (i) advised to board the vehicle when a temperature of the potential passenger is equal to or below a prescribed temperature threshold or (ii) advised to refrain from boarding the vehicle when the temperature of the potential passenger exceeds prescribed temperature threshold.

Abstract: A headcount determination system is disclosed that includes a first camera and a processing unit configured to receive data communications that include an image frame captured by the first camera. The processing unit includes logic that, when executed by the processing unit, causes performance of operations including performing operations comprising a pre-processing phase including dividing the image frame into sub-frames, performing operations comprising an inference phase including scoring the sub-frames with a machine learning (ML) model, performing a threshold comparison with a score for each sub-frame and a threshold, and incrementing a headcount when the score satisfies the threshold comparison, and when the threshold comparison has been performed for the score for each sub-frame, providing the headcount as output. The operations further include performing a scaling operation on the image frame that adjusts a size of the image frame by a scaling factor.

Abstract: An orthopedic cast removal apparatus comprises a housing having a portion that can be gripped by an operator during use. A motor is located inside the housing. A blade is operatively connected to and driven by the motor via a drive mechanism, the blade defining a cutting edge having cutting teeth located thereon. The drive mechanism according to this aspect has a driven element with an axis of rotation substantially parallel to a surface of an orthopedic cast when it is cut. The blade is connected to the driven element at a connection point that moves periodically around the axis of rotation. As a result, the cutting edge of the blade engages material of the orthopedic cast in a galloping fashion.
