Abstract: A self-assessment system for assessing risk for experiencing abnormal airflow during sleep. A preferred embodiment of the system includes a cannula for sampling nasal airflow of a user. A data recording and communication device includes a sensor to receive airflow from the cannula, a converter to convert breathing airflow to an electronic signal, a recorder to record electronic signal data, and a transmitter to wirelessly transmit said electronic signal data. A mobile device includes a receiver to receive said electronic signal data transmitted from the recording and communication device, a database to store the electronic signal data, an interface to obtain questionnaire data from the user, a transmitter to wirelessly transmit the electronic signal and questionnaire data, and a mechanism to store or access instructional video information.

Abstract: A propellant ignition testing apparatus having a compressively sealable chamber. A fixed end plate assembly is fixedly mounted on a support structure. A test chamber assembly having a combustion chamber for accommodating propellant is provided, and an initiator ignites propellant accommodated in the combustion chamber. A moveable end plate is disposed adjacent to the test chamber assembly on a side thereof remote from the fixed end plate assembly. A device is mounted on the support structure for generating a compressive force, with the moveable end plate being operatively connected to a moveable component of the device for moving the moveable end plate toward the test chamber assembly for sandwiching the combustion chamber of the test chamber assembly in a compressively sealed manner between the fixed end plate assembly and the moveable end plate.

Abstract: A storage system for storing products is provided that includes a frame having a first side and a second side opposite the first side and a dynamic support carried by the frame. A mover assembly is carried by the frame and is configured to engage an area of a product at rest on the dynamic support. The mover assembly moves the product along the dynamic support relative to the frame from a first location near the first side to a second location near the second side.
