Abstract: A method of determining a seat back status of a passenger seat in a vehicle. The method includes monitoring a seat back orientation sensor coupled to a seat back of the passenger seat and monitoring a reference orientation sensor coupled at a fixed position within the vehicle. The seat back orientation sensor determines an orientation of the seat back relative to Earth, and the reference orientation sensor determines an orientation of the vehicle relative to Earth. The method further includes determining an orientation of the seat back relative to the vehicle based on a comparison between the orientation of the seat back and the orientation of the vehicle relative to Earth, and transmitting seat back orientation data, of the seat back relative to the vehicle, to a remote monitoring unit, wherein the remote monitoring unit is configured to display a first notification when the seat back is not fully upright.

Abstract: Disclosed is a planar test bed comprising a planar surface and further comprising mechanical couplings in mechanical communication with the planar table and the supporting legs. The mechanical couplings are translatable to provide three degrees of freedom for orientation of the planar surface. A processor receives position and velocity information describing an object on the planar surface, and calculates a relative acceleration typically using a function aR=f(t,xR,vR,?t). The processor communicates with the mechanical couplings to establish an orientation where a local gravity vector projects onto the planar surface and generates acceleration with magnitude and direction substantially equal to the desired acceleration aR The operations occur in cyclic fashion so the desired accelerations and planar orientations are updated as an object transits over the planar surface.

Abstract: A self-levelling system comprising a base (10) fixed onto a first external load-bearing structure subjected to natural stressing forces, a second internal flat structure (21) which is to be self-levelled, and a movable fixing system between said first and second structure.

Abstract: A transportation apparatus includes a payload receiving unit, a transportation body, and a compensation system arranged there between providing adjustment of a desired spatial relationship of a payload surface of the compensation unit. The compensation system has at least one of a first compensation unit and a second compensation unit for adjustment of the spatial relationship. The compensation units adjust the spatial relationship in different directions. Thus the compensation system maintains a desired orientation of the payload surface independent of changes of orientation of the transportation surface. Further, the compensation system substantially maintains a common point of gravity of the transportation apparatus including the payload by displacing the center of gravity of the payload receiving unit and the payload substantially opposite to a displacement of a center of gravity of the transportation apparatus.

Abstract: A chair is stabilized in two orthogonal axis, pitch and roll, can hold a person stable in relation to the horizon. This solution to motion sickness is effective because the fluid in the inner ear no longer moves in relationship to the vehicle motion upon which the person is located. Therefore a main cause of motion sickness is substantially reduced or eliminated. Additionally, the invention can be a table, a bed, or even an entire room that is isolated from the rolling, pitching and jolting imparted by the host vehicle. Additionally, some applications such as a chair and table, may be stabilized in a third orthogonal axis, azimuth.

Abstract: An active deck suspension system for use in marine vessels having a hull and an operator deck. A custom chassis includes pneumatic cylinders which absorb impact forces acting upon the boat hull or suspension deck, and also includes auxiliary emergency jacks. The chassis includes an upper support member which is affixed to the suspension deck, and a lower base support which is complementary to, and mates with, the bottom of the hull. The suspension deck will deflect, in a controlled manner, upon the boat encountering impact forces created by rough seas, or the like. The system includes control circuitry and constantly monitors the suspension deck to automatically compensate for load forces, and thereby provides a substantially improved occupant ride.

Abstract: An anti-motion sickness mechanism comprises a platform suspended from a conveyance for movement about all principal axes. Any vertical movement of from 0 to 0.5 Hz has a tendency to cause motion sickness. A supplementary vertical movement of about 2.5 Hz is added to the platform to break up such vertical movement into sub-movements having a reduced tendency to cause motion sickness.

Abstract: A suspension system for a bed or bunk which is to rest on a substantially horizontally oriented deck and is particularly adapted for the sleeper compartments of large truck cabs and which substantially reduce the amplitude of vibrations and other disruptive movements of the truck. The system includes a lower support frame which is adapted to be on the deck. An upper support frame for supporting a mattress is positioned above the lower support frame. The two frames are interconnected by at least two torsion spring members wherein the upper support frame is free to move up and down relative to the lower support frame under the influence of the spring action of the torsion spring members. The spring action dampens the transmission of up and down movements from the truck to the upper support frame and the mattress positioned thereon.

Abstract: A reactive attitude stabilization system to be carried by a vehicle is provided where a first shaft is pivotally mounted on the vehicle in a normally horizontal relation. A second shaft is supported in horizontal relation at its midpoint by the first shaft and oriented perpendicular to the first shaft. Nonrotating slide bearings support a platform on the second shaft for translation of said second shaft relative to the platform. Resilient members oppose translation of the second shaft relative to the platform in either direction and normally maintain the intersection of the axes of the first and second shafts vertically above the center of gravity of the platform. An acceleration induced shift of the second shaft axially and horizontally relative to said platform causes a torque due to gravity to counteract the acceleration dependent torque.

Abstract: A marine stove comprises a valve body for coaxial connection to a nipple on a pressure gas bottle, a tubular mixer coaxially telescopingly threaded into the top of the valve body, a burner above the mixer that is coaxially supported by it, and a grill over the burner, also supported by the mixer. A pivot confined between the valve body and the mixer has opposite laterally projecting coaxial trunnions that define one gimbal axis for the stove. Another gimbal axis is defined by a shaft that has a head at a rear end thereof and a U-shaped yoke at its front with forwardly projecting legs that have upwardly opening grooves wherein the trunnions are received. A mounting plate securable in forwardly offset relation to a bulkhead has a shaft hole through which the head is received. The shaft is rotatably supported in forwardly projecting relation to the plate by a bracket that hooks into the plate and has upwardly projecting abutments between which the shaft is closely received.

Abstract: The invention is particularly adpated to support refrigerators in recreational vehicles, to maintain the refrigerators in level condition, although the invention may be adapted for use in supporting other appliances, such as stoves and the like. The gas-fired absorption type of refrigerator is the most popular type for travel trailers, but it must be maintained in level condition in order for it to operate properly. My invention provides a support for a refrigerator wherein the latter is always gravity-urged to level condition. Dash pot devices are included to yieldably oppose movement of the refrigerator, so that the latter moves gently from one position to another in accordance with the angularity of the terrain over which the travel trailer travels or on which it is parked. The supporting means may be built as part of the refrigerator at the factory, or it may be offered in kit form for installation on refrigerators already in use or on the market.

The beam system is connected to each float by a transverse articulation oriented perpendicular to the longitudinal axis of these floats. Structure comprising a differential is provided between the beam system and each float to maintain this beam system in a mean position relative to the floats. This differential may be of the hydraulic or mechanical type and under the control of a gyroscope. The cockpit is mounted at the middle of the beam system and is articulated about an axis oriented according to the longitudinal axis of the boat. Structure, such as a jack controlled by a gyroscope, is provided to maintain the cockpit in a horizontal position. A boat of this type, endowed with good stability, is useful particularly as a pleasure craft, passenger craft or as a service craft.
