Abstract: A filler device includes a distal housing comprising a distal inner port and a distal outer port; a proximal housing comprising a proximal inner port and a proximal outer port, the proximal housing being sealingly affixed to the distal housing to form an inspiratory pathway between the distal inner port and the proximal inner port and to form an expiratory pathway between the distal outer port and the proximal outer port that is fluidly sealed from the inspiratory pathway, the inspiratory pathway being laterally adjacent the expiratory pathway; and a first filter in the inspiratory pathway or in the expiratory pathway to filter gases flowing through the inspiratory pathway or the expiratory pathway.

Abstract: Disclosed is a haptic feedback device for converting virtual environment data into haptic feedback. Haptic feedback device can have a housing configured to receive a motor. The motor can be coupled to a camshaft and a main bladder disposed beneath the camshaft within the housing. The main bladder can be coupled to a valve controller via tubing and the valve controller can have a manifold and one or more valves. The one or more valves can be coupled to one or more haptic sensors via secondary tubing.
