Abstract: A method and apparatus for forming a composite structure. An inner tooling, a stackup, and an outer tooling are held in place together using a load constraint. A bladder and a plurality of stringer bladders in the stackup are pressurized to cause expansion of the bladder and the plurality of stringer bladders, thereby pushing together an overbraided thermoplastic skin and a plurality of overbraided thermoplastic members in the stackup. The overbraided thermoplastic skin and the plurality of overbraided thermoplastic members are co-consolidated while the bladder and the plurality of stringer bladders are pressurized to form the composite structure.

Abstract: Described herein are systems and methods for favorably coordinating a timing relationship between a musculoskeletal activity cycle and a cardiac cycle of a user. A method may include repetitively detecting a signal that correlates to a blood volume in the user; determining an actual value of the signal that varies with the timing relationship; computing a trend of the actual value of the signal; and adjusting the movement guidance based on the trend of the actual value. A system may include a prompt device configured to provide recurrently a movement guidance to the user for guiding performance of the rhythmic musculoskeletal activity; a sensor configured to provide a signal that correlates to a blood volume in the user; and a processor configured to determine an actual value of the signal that varies with the timing relationship and to adjust the movement guidance based on the trend of the actual value.

Abstract: The present calibratable tire gauge has a first unit nose piece and a second unit nose piece located partially within a main outer enclosure of the gauge. A clicker mechanism located may allow a user to utilize a special tool to ‘unlock’ the second unit nose piece with respect to the first unit nose piece and immobilize the second unit nose piece with respect to the main outer enclosure. Once ‘unlocked’, a user may twist the scale bar of the gauge to move the first unit nose piece independent from the second unit nose piece. As a result, the measured pressure on the scale bar is altered as a result of the ‘read’ line being lowered or raised with respect to the main outer enclosure.

Abstract: An apparatus for coating glass articles includes a housing structure defining a chamber for receiving air or other fluid from a source of pressurized air that is in fluid communication with the chamber. The housing structure has an open end and a surface defined along at least a portion of the open end. A hot-swappable insert is removably positioned on the surface. The hot-swappable insert has a series of apertures for distributing the air or other fluid from the chamber and onto a surface of the glass articles that are positioned adjacent the insert. The insert can be replaced with another insert to adjust the flow path of the air or other fluid onto the glass articles.

Abstract: In described examples, a DC-DC converter provides electrical power. In response to an input voltage falling below a high voltage operation threshold, the converter repeatedly performs a first normal (N) phase and a second N phase. The first N phase includes delivering power through an inductor from the input voltage. The second N phase includes coupling an input terminal of the inductor to a ground. In response to the input voltage rising above a normal operation threshold, the converter performs a first high voltage (HV) phase, then a second HV phase, then a third HV phase, then the second HV phase, and then repeats from the first HV phase. The first HV phase includes delivering power through the inductor from the input voltage and charging a flying capacitor. The second HV phase includes coupling the input terminal of the inductor to the ground. The third HV phase includes delivering power through the inductor by discharging the flying capacitor through the inductor.
