Abstract: One variation of a method for deriving and storing emotional conditions of humans includes: writing timeseries biosignal data, output by a set of biosensors in a local device coupled to a user, to a rolling buffer spanning a look-back duration; in response to a trigger event at a first time, retrieving a set of biosignal data, spanning a first period of time preceding the first time, from the rolling buffer; transforming the set of biosignal data into a timeseries of emotions exhibited by the user during the first period of time; generating a visualization of the timeseries of emotions; and rendering the visualization of the timeseries of emotions on a display.

Abstract: The present invention provides a compact hoist system for use on a drilling or workover rig. The present invention eliminates problems related to chain failures in hoist systems by incorporating wire rope in a vertically and horizontally compacted arrangement to provide maximum vertical lift capacity and improved versatility. Caterpillar bearings, wire rope tension equalizing sheaves and a winch coupled to a axially movable spiral-grooved drum are combined to provide a system that enables cantilever jack-up rigs to handle blow-out preventer stacks of increased height and size.
