Abstract: Systems and techniques are disclosed for aspects of audiovisual content selection based on collecting and processing physiological data. In an example, a system comprises: a sensor device with at one physiological sensor to capture physiological data from a human subject; an output device with a display device to output video and a speaker to output audio to the human subject; and a computing device with at least one processor to control an output of digital audiovisual data to a human subject via the output device, based on data processing operations including a comparison of an observed pattern of autonomic nervous system activity to a target pattern of autonomic nervous system activity.

Abstract: A tilt-trim subsystem assembly affixed to an outdrive of a stern drive that may be supported by a gimbal unit and may be configured to rotate about a predetermined axis to impart a desired trim or tilt to the drive system is provided. The tilt-trim assembly has one respective end thereof configured to pivotally receive one anchor pin supported by the outdrive. The assembly includes one or more cylinders having one end thereof pivotally connected to another anchor pin so that when the cylinder is actuated the outdrive and the tilt-trim subsystem assembly are jointly rotated about the predetermined axis.

Abstract: The invention provides a marine propulsion device comprising a powerhead including an exhaust gas discharge port, a gearcase rotatably supporting a propeller shaft connected to the powerhead and including an exhaust gas discharge, and a lower unit including an upper portion supporting the powerhead and a lower portion connected to the gearcase, with the lower unit comprising an inner exhaust housing having a generally vertical wall, an open top in communication with the powerhead exhaust gas discharge port, a bottom having therein a first exhaust gas outlet and a second exhaust gas outlet at the top portion of the wall, and an outer exhaust housing also having a generally vertical wall in surrounding relation to the inner exhaust gas housing and defining a vertically extending generally annular space between the inner and outer exhaust gas housings, the space communicating with the second exhaust gas outlet.

Abstract: An engine including an engine block, and spark timing structure for advancing and retarding spark timing between a minimum spark advance and a maximum spark advance, the spark timing structure including a spark timing link comprising a stop and being movable between a minimum advance position and a maximum advance position spaced in one direction from the minimum advance position, the spark timing structure also including a spark timing lever including a surface and being movable between a first position wherein the surface is spaced from the stop when the link is in the minimum advance position, a second position wherein the surface engages the stop when the link is in the minimum advance position so as to provide common movement of the link and the spark timing lever in response to further movement of the lever in the one direction, and a third position wherein the link is in the maximum advance position when the surface engages the stop.

Abstract: An internal combustion engine comprising an engine block defining a cylinder bore and a fluid jacket, an annular valve seat defining a first passageway communicating with the fluid jacket, a valve assembly including a housing having a fluid inlet, a fluid outlet, a second passageway communicating between the inlet and the outlet, a second valve seat located in said second passageway, and a partially spherical outer surface portion moveable into and out of seating engagement with the annular valve seat, a valve member in the housing, and a mechanism for moving the valve member into and out of seating engagement with the second valve seat for respectively closing and opening said second passageway, and a mechanism for biasing the partially spherical outer surface portion into seating engagement with the annular valve seat.
