Abstract: A body stabilizer for exercising includes a rear member, two side members, and two padded members. The rear member is configured for positioning on the floor and against a wall. The side members are spaced from each other and coupled to the rear member. The padded members are coupled to the two side members and configured for abutting shoulders of a user. The padded members are space apart an approximate width of the shoulders of the user. The side members are configured to prevent a body of the user from moving toward the wall.

Abstract: A computer-implemented method of machine learning classification for Computer Assisted Design (CAD) is provided. The method comprises receiving a number of CAD volumes comprising a dataset, wherein each CAD volume is characterized by a number of scalar values corresponding to features of the CAD volume, wherein the features rely on geometry queries from a CAD kernel. Each CAD volume is labeled with part names according to a set of categories defined by a user, and a machine learning model is trained with the features of the labeled CAD volumes.

Abstract: A computer-implemented method of enhancing a computer to estimate an uncertainty of an onset of a signal of interest in time-series noisy data. A first mathematical model of first time series data that contains only noise is calculated. A second mathematical model of second time series data that contains the noise and an onset of a signal of interest in the second time series data is calculated. A difference is evaluated between a first combination, being the first mathematical model and the second mathematical model, and a second combination, being the first time series data and the second time series data, wherein evaluating is performed using a generalized entropy metric. A specific time when an onset of the signal of interest occurs is estimated from the difference. An “a posteriori” distribution is derived for an uncertainty of the specific time at which the onset occurs.

Abstract: An exercise device has a first frame, where the first frame is generally rectangular and has a head end and a first juncture end. A fixed body support is fixed on the first frame and is configured to support a torso of an exercise participant. A second frame has a second juncture end, a foot end and a pair of rail members extending along opposite sides of the second frame, respectively, between the second juncture end and the foot end. A carriage is mounted on the second frame for movement along the rail members along locations confined between the second juncture end and the foot end. Wheels mounted to the carriage facilitate movement of the carriage along the rail members, among other things, prevent the carriage from tilting upwardly as it is driven toward the foot end.
