Abstract: A system, method, and computer-readable medium for generating factual and/or counterfactual data are described. This may have the effect of improving the complexity of data available for training machine learning models. The models may include, but not limited to, a probabilistic graphical model (PGM) and/or an agent-based model (ABM). Further aspects may provide for scrubbing actual data to create a data model that does not reveal the content of the underlying source data. Yet further aspects may provide for validating a data model.

Abstract: A system and method includes a loudspeaker having a first, low-frequency driver and a second, high-frequency driver. An error microphone is disposed near the loudspeaker and receives sound output by both drivers as well as noise. An estimation of the secondary path between the drivers and the microphones is determined, and playback audio is applied to the estimation. The output of the estimation is subtracted from the output of the microphone to determine anti-noise. This anti-noise is used to modify audio data sent to the first, low-frequency driver; the audio data is sent directly to the second, high-frequency driver.

Abstract: A sleeping bag has an elongate shell defining a longitudinal centerline and an inner volume sized and shaped to receive a user therein, the shell having a head portion, a foot portion, a middle portion extending longitudinally between the head and foot portions, an overlying portion adapted to overlie the user during use, and an underlying portion adapted to underlie the user during use. A blanket is coupled to the shell and configured to selectively move between a closed position within the inner volume and an open position beyond the shell.

Abstract: A multi-purpose receptacle includes a bottom panel and a sidewall attached to the bottom panel. The sidewall extends from the bottom panel in a longitudinal direction. The sidewall includes a side panel and an inflatable bladder attached to the side panel. The side panel extends around at least a portion of the bottom panel. The inflatable bladder includes a sealed cavity for containing an amount of gas, and defines a portion of the sidewall.

Abstract: Disclosed is a belt buckle assembly with magnetically interchangeable faceplates. The faceplate attaches to a base plate by a magnetically active plate on both the base plate and the faceplate. The base plate is concealed by the faceplate when the belt buckle is assembled and in use. The user's belt is attached by a belt loop at one end of the base plate and a post on the back side of the base plate which protrudes through a hole in the belt end opposite the belt loop.
