Abstract: A ventilator headboard apparatus is a modular air handling and filtration device used to recirculate and filter a volume of air. A chassis supports at least one mounting panel, a supply plenum, and a cover plate to manage the atmosphere at the head of a patient's bed, i.e., at the headboard. A plenum space is formed between the supply plenum and the cover plate, across the mounting panel. A pressurized conduit is connected between the supply plenum and an air handling unit, arranging the air handling unit in fluid communication with the plenum space directly, and the atmosphere around a patient's head by extension. With operating energy supplied by a power supply, the air handling unit is used to operably intake or exhaust air across the cover plate according to user configurations and situational requirements.

Abstract: The exercise devices disclosed herein are configurable to allow a user to perform various exercises. The exercise device can include an adjustable bench assembly connected with a frame supporting a cable-pulley assembly providing a user interface with a resistance system. A user can interface with an actuation component to pull resistance cables against resistance from the resistance system. Various exercise accessories can be provided that are easily connected with and removed from the exercise device to allow a user to perform different exercises. Some examples of exercise accessories are used to configure the exercise device for squat, abdominal, leg extension, leg curl, and arm curl exercises. The frame can also be configured to selectively place the exercise device in a stationary operating configuration supported by the frame on a support surface and a storage configuration wherein the exercise device is rollingly supported on the support surface by wheels.
