Air bag inflation device
This invention relates to active protective garments which are inconspicuously worn by an individual and which activate upon certain conditions being met. Activation causes inflation of regions of the active protective garment to provide padding and impact cushioning for the wearer. The invention is an active protective garment such as pair of shorts or pants, a jacket, a vest, underwear, and the like. The garments comprise multiple layers of material that constrain pockets or regions that are inflatable by a source of compressed gas or foam. The garments also comprise sensors to detect ballistic parameters such as acceleration, distance, relative acceleration, and rotation. The sensor information is used to determine whether activation is required. Detection and activation are accomplished in a very short time period in order to offer maximal protection for the individual wearing the garment. The system comprises a computer or logic controller that monitors the sensor data in real time and coordinates the information from all sensors. The system calculates velocity, distance, and rotational velocity. A rule-based system is used to detect a complex fall in progress and discriminate said fall in progress from the events of every day life. The pockets or inflatable regions of the garment protect the individual against falls and other impacts that may cause bone fracture or organ damage.

Inflatable mattress and control methods
ActiveUS20140059781A1Reduce pressure soresReduce air pressureStuffed mattressesSpring mattressesPhysical medicine and rehabilitationPhysical therapy
A patient support, such as a mattress, includes a plurality of inflatable bladders. Depth sensors are included in the support that measure the degree of penetration of a patient into the mattress. An air pressure sensor is also included that measures the pressure inside at least one bladder. A suitable inflation level of the mattress is determined by monitoring the rate of change of the depth with respect to air pressure as the bladder is either inflated or deflated. By detecting an inflection point in the graphical relationship of the depth and pressure outputs, a suitable inflation point for the bladders is determined that reduced interface pressures experienced by the patient, yet does not overly sink the patient into the mattress to a degree or discomfort. Analyzing the outputs of the depth and pressure sensors can also be used to detect a patient's heart rate and respiration rate.

The adaptive multi-stage inflator comprises a housing, a primary igniter assembly and a secondary igniter assembly. The housing has a top wall, a bottom wall and a side wall, which together define an interior chamber therebetween. The primary igniter assembly is disposed in the interior chamber of the housing and is configured to initiate the generation of a primary inflation fluid to inflate an air bag. The secondary igniter assembly is also disposed in the interior chamber of said housing. The secondary igniter assembly is configured to augment the primary inflation fluid by producing a secondary inflation fluid to further inflate the air bag. The inflator also includes a bypass assembly that is configured to provide the secondary inflation fluid to the air bag at substantially the same temperature as it was produced by the secondary igniter assembly, thereby increasing the pressure of the primary inflation fluid. The bypass assembly comprises a bypass passage configured such that the secondary igniter assembly is in direct fluid communication with the air bag. The bypass assembly has a retainer disk which in combination with the interior surface of the housing defines the bypass passage. The inflator also includes a filter disposed in the housing proximate to the side wall thereof to prevent the passage of particulates. The bypass assembly is configured to direct the secondary inflation fluid to the air bag without the secondary inflation fluid passing through the filter.

Radio-frequency (RF) leakage from shielded enclosures is minimized while ensuring applicable RF attenuation standards and access requirements of the Americans with Disabilities Act (ADA) by attaching an inflatable bladder to a door of an enclosure. Substantially surrounding the bladder is an electrically conductive material. When the bladder is inflated it makes contact with conductive material which in turn makes conductive contact with the door frame to create an RF seal. The use of the bladder and conductive material provides an improved RF seal and allows for the use of a low-profile threshold that permits ADA access to, and from, the enclosure.
