Load control apparatuses, systems and methods to control a location, orientation, or rotation of a suspended load by imparting thrust vectors to the suspended load or to a structure that holds the load. The load control apparatuses, systems and method may be integrated into a structure that holds a load, such as a rescue litter. The load control apparatuses, systems, and methods may be modular. The modular load control apparatuses, systems, and methods may be secured to a load or to a structure that holds the load.

A backrest device that normally supports the occupant and moves forward with said occupant during a forward impact/crash event. The device is equipped with a spring activated biased ratcheting mechanism that provides only forward movement, thus reducing the amount of dangerous rear excursion during the rebound phase, as measured by the occupant's head and torso.

Human stabilization platforms may include a support structure configured to rigidly support a person. A rail may extend longitudinally from proximate a portion of the support structure configured to receive the person's head thereon to proximate a portion of the support structure configured to receive the person's lower legs thereon on each lateral side of the support structure. Each rail may include selectable attachment structures distributed along at least a portion of the longitudinal length of the rail. The selectable attachment structures may be configured to receive modular accessories to be secured to the human stabilization platform. A handle may be located at each end of each rail, each handle being rotatable with respect to the rail. Each handle may be configured to enable manual handling and transport of the human stabilization platform.

A spring supported tray for mitigating a dominant frequency imparted thereto is provided. The spring supported tray includes a tray including a topside and underside, and configured to support an object on the topside, and N springs supporting the tray, N being a positive integer. A first end of each of the N springs is disposed at the underside of the tray. A second end of each of the N springs is disposed so as to receive vibrational motion imparted to the second end of each of the N springs from a source of the vibrational motion, the vibrational motion having a dominate undesired frequency Each of the N springs has a spring constant k defined by the equation:

[00001]$k=\frac{f_n^2.Math.4.Math..Math.{}^2.Math.w}{\mathrm{Ng}}$

where w denotes the collective weight of the tray and the object, g denotes the force of gravity, and f.sub.n denotes a natural frequency of the spring supported tray supporting the object, wherein f.sub.n is a lower frequency than the dominate undesired frequency f.sub.dom.

The invention relates to an apparatus for protecting the safety of persons, in particular wheelchair users, in a vehicle, comprising a headrest and/or backrest at least one holder, to which the headrest and/or backrest is attached, for holding the headrest and/or backrest, wherein the holder is adapted to change the horizontal distance (X.sub.K) of the headrest and/or the horizontal distance (X.sub.R) of the backrest in the direction of travel from the person. The invention is characterized in that the holder includes at least one cushioning device for cushioning the impact of a person or a wheelchair against the headrest and/or backrest.

A system and method of using, a mounting system for large medical equipment. The system can include a sled assembly and a pair of spaced parallel rails. The pair of rails can be mounted to the floor of a vehicle. The sled assembly can be coupled to the pair of rails and operable to move horizontally parallel to the longitudinal axis of the pair of rails. Large medical equipment can be coupled to the sled assembly allowing movement of the medical equipment.

A transport incubator comprising an incubator, frame, and supporting components. The incubator is self-leveling, vibrationally isolated, and features active noise canceling or reduction. The frame is composed of lightweight composites and features composite air tanks.

Disclosed are systems, apparatuses, and methods for and related to dynamic control of torque and or lateral thrust applied to a load suspended load on a suspension cable to thereby achieve a target orientation or position or to otherwise move through use of a hyperparameter, wherein the hyperparameter comprises a normalized moment of inertia, wherein the hyperparameter comprises a ratio of a force command to a thruster and an angular acceleration.

A pre/post-tensioning controller system for a wheelchair tie-down and occupant restraint system (WTORS) will be a comprehensive energy management system for controlling excessive excursions of a wheeled mobility device during various adverse driving scenarios. The system uses multiple pre-tensioning and post-tensioning events during a front, side, or rear impact crash or rollover scenarioand effectively controls excursions by the tensioning of the WTORS equipment at specific and ideal moments. The system also uses tensioning events on the tie-down equipment during a long duration turn or other aggressive maneuvers. The system may also use tensioning events on the occupant restraints. The energy management system can be adapted for use with traditional four-point tie-downs and newer three- and two-point tie-down systems that incorporate fixed or movable bumpers, as well as compressive-type securement systems, and other systems as well, including docking systems.
