  • Patent number: 11657208
    Abstract: Systems, methods, and non-transitory, machine-readable media to facilitate adaptive processing and content control are disclosed. Content composites may be created and configured according to a computational model that may include a hierarchical ordering of the content composites using a hierarchical data structure. The configured content composites may be presented with a graphical user interface of an endpoint device. Metrics of interactions with interface elements corresponding to the configured content composites may be determined using a processing device that monitors inputs. The computational model may be automatically trained using the metrics of interactions to create an adapted computational model. Adapted content composites may be created and configured according to the adapted computational model that may include a second hierarchical ordering using a second hierarchical data structure. The adapted content composites may be presented with the graphical user interface.

  • Patent number: 9004204
    Abstract: A lightweight motorized and tracked sled for attachment to a variety of stair chairs is described. A power supply or power source provides power to a motor driving a track configured to engage a set of stairs. The motor and track can lift and support the stair chair and a patient thereon up or down one or more flights of stairs. The track driven by the motor has a length sufficient to simultaneously engage the lips or edges of a pair of sequential steps, but may be otherwise limited in length to reduce the weight of the track. To ensure that the sled and attached stair chair are stably supported while ascending or descending stairs, the sled may have rails, skis, or passive tracks having a length sufficient to ensure that the rails, skis, or passive tracks are always over the edge or lip of no fewer than two steps.

  • Publication number: 20110025004
    Abstract: A moldable and stackable evacuation sled that can also be used as a temporary surge capacity bed includes a dual-layer molded sled body having an air space between an inner layer and an outer layer. The sled body has a low-friction bottom surface, a bearing surface having a length and width that renders the bearing surface capable of receiving a human in a prone position, and upturned head, side, and foot portions that are substantially contiguous with the bearing surface and with each other. The sled body also includes a plurality of holes formed in at least the side portions, where the holes are adapted to receive a strap. A circumferential strap is threaded through at least a portion of the holes. Tow straps pass through other holes and loop around the circumferential straps.

  • Patent number: 7699324
    Abstract: A lightweight, strong, sturdy, and versatile evacuation sled is disclosed. The body of the sled may be manufactured from a single piece of material, stored flat, and folded into its functioning configuration. When folded, the sled has one or more straps that help hold it in its folded configuration and allow maneuvering or carrying the sled. The sled may be readily towed with a towing harness and may be moved down an incline, such as stairs, by means of a rope and belay device. The sled has a low coefficient of friction and is lightweight, allowing the sled to be readily moved and handled without requiring the assistance of multiple people. Additional sleds with foam inserts may be provided to carry equipment such as for life support. The sled may also provide surge capacity for facilities like hospitals, as the sled is designed to be inexpensive and essentially disposable.

  • Publication number: 20090022923
    Abstract: Apparatuses and methods for providing an information recording system that enables a paramedic to record and transpose vital signs during an emergency are disclosed. The information recording system may include one or more printed decals which may be written on during a response to an emergency and may then be affixed to one or more pages of a corresponding run report. The printed decals may include vital sign categories with associated recording means such as fill-in-the-blank locations, checkboxes and numerical alternatives, such as for taking measurements. The printed decals may be affixed to more than one surface before finally being affixed into a corresponding run report. By affixing the printed decal into an associated run report the recorded information is thereby effectively transposed into the report entirely. The decal may be printed directly on surgical or other tape or may be originally affixed to a backing and provided thereon.

  • Publication number: 20080272629
    Abstract: A collapsible emergency vehicle chair cot that includes a support system and a movement system is described. The movement system is coupled to the support system and utilizes rotational movement to assist in moving the chair cot over a surface. The support system and movement system are configured to be collapsible to facilitate using the chair cot with an emergency vehicle. The chair cot may include at least two removable platforms for supporting a patient in a seated position. Furthermore, the chair cot may include one or more options for transporting equipment, including an equipment transport basket that may take the place of the removable platforms.

  • Patent number: 7124454
    Abstract: An ambulance cot is provided having a wheeled carriage, a frame for mounting the wheels, a horizontally oriented patient litter supported from the wheeled carriage and variable, pneumatically powered height scissors frame. The pneumatic actuator is designed to give a patient air-ride transportation and an adjustable height litter for lifting a patient from the ground. The patient litter has a pivoting hinge for transporting a patient down stairs. This pivot will allow the stretcher to pivot to a horizontal angle while going down stairs, for patient support and ease of transportation for said operator below. One embodiment has tracks attached over the wheels to provide a more stable and smooth ride as the cot is moved down stairs. Another embodiment comprises a translational trolley configuration. A hand brake is mounted on the patient litter for braking the tank-like motion of the tracks.
