  • Patent number: 9301397
    Abstract: Metalized web substrate is wet etched in a reaction vessel by contacting with oxidizing and metal complexing agent to remove metal from unpatterned region. Following etching, substrate is rinsed, and rinse is at least partly recycled. Concentrations of oxidizing and metal complexing agents in the etchant bath are maintained by delivering replenishment feeds of each. Concentration of metal in the etchant bath is maintained by discharging some of the etchant bath. Replenishment rates of oxidizing and metal complexing agents and etchant removal rate are determined based at least in part on rate that metal etched from the substrate enters the etchant bath.

  • Publication number: 20150069758
    Abstract: Disclosed illustrative embodiments include systems and methods for power peaking with energy storage. In an illustrative, non-limiting embodiment, a power plant includes a thermodynamic piping circuit having a working fluid contained therein, and the working fluid has a flow direction and a flow rate. Power plant components are interposed in the thermodynamic piping circuit. The power plant components include a compressor system, a recuperator system, a heat source, a turbine system, a heat rejection system, and a thermal energy transfer system. A valving system is operable to selectively couple the heat rejection system, the thermal energy storage system, and the compressor system in thermohydraulic communication with the working fluid maintaining the flow direction and the flow rate to implement a thermodynamic cycle chosen from a Brayton cycle, a combination Brayton cycle/refrigeration cycle, and a Rankine cycle.

  • Patent number: 8875709
    Abstract: A mask assembly adapted for use with a positive airway pressure device, includes a mask frame, an elbow assembly provided to the frame, a cushion provided to the frame, a forehead support assembly, and a neck to connect the frame to the forehead support assembly, wherein the neck includes a pair of side walls having a streamlined design that is made to look sleek and reduce or minimize obtrusiveness. The pair of side walls may take the form of a single wall or more than two walls. The mask frame may include a recessed port structure including at least one port having access to an interior of the frame which at least in part with the cushion defines a breathing chamber in communication with a nasal passage of the patient in use. The mask frame may also include a channel to receive the cushion. The channel is formed by an outer wall and an inner wall and the channel includes an inner surface having a bead to engage with an outer surface of an edge of the cushion.

  • Patent number: 8840919
    Abstract: A medicant composition is provided. The composition includes a film layer and a powder matrix layer. The powder matrix layer includes a medicant. The powder matrix layer is applied to the film layer by admixing particulate to form a powder matrix and by then applying the powder matrix to the film layer by any desired method. The composition of the powder matrix is varied to alter the dissolution rate of the medicant, the adhesion of the medicant composition, and other physical properties of the powder matrix. The powder matrix layer can be cured.

  • Publication number: 20140199672
    Abstract: A system and apparatus for allowing a trainee to replicate the body movements of a trainer. A trainer's instructional body movements are recorded using sensors on the trainer's garment and then stored in a computer. A trainee's body movements are then recorded using a similar set of sensors on the trainee's garment. The computer can then compare the trainer and trainee body movements to assist the trainee in better replicating the trainer's body movements. The trainee's garment can be provided with physical devices, such as neuromuscular electrical stimulators and/or robotic actuators, to physically assist the trainee in real time to better replicate the trainer's body movements. Such physical devices may also be included on the trainer's garment so that the trainer can better understand any mistakes made by the trainee.
