  • Publication number: 20120062708
    Abstract: A fabrication system comprises one of a substrate and work piece having at least one working surface, a tool coupled to a tool holder, at least one measurement system, and a control system. The at least one working surface comprises one or more regions. A first location of the tool, tool holder, and the one of a substrate and work piece are calibrated with reference to a coordinate system. The tool is adapted to affect creation of a device within the one or more regions. The at least one measurement system is adapted to obtain location information of at least a portion of at least one of the tool, tool holder, and one of a substrate and a work piece. The control system is adapted to receive the location information, determine a second location, and provide one or more output signals to one or more adjustment devices.

  • Patent number: 8114465
    Abstract: Processes are provided for preparing a substrate coated with a biomolecule, comprising: a) providing a substrate; b) coating the substrate with a polysiloxane, typically by exposing the substrate to a reactive gas containing siloxane functional groups and to plasma energy to yield a plasma-deposited polysiloxane surface on the substrate; c) rendering the polysiloxane surface amino functional; and d) contacting the amino-functional polysiloxane surface with a biomolecule under conditions effective to attach the biomolecule to the substrate. The coated substrate may be a medical device that demonstrates an ability to maintain gas permeability when in contact with blood or blood components, compared to a substantially identical medical device that has not been coated with a biomolecule using this process.

  • Patent number: 7230574
    Abstract: An oriented PIFA-type apparatus for reducing hearing aid radio frequency (RF) interference including a directional multi-band and/or single band antenna for use with PWDs such as digital cellphones is disclosed. The apparatus greatly reduces or eliminates the audio noise induced in hearing aids by the PWDs and allows operation of a hearing aid during PWD operation. In operation, the apparatus may be provided on the PWD side away from the user's head. The apparatus may be integrated into the PWB during its manufacture or provided as an after market assembly for a PWD that has a port for connection of an external antenna. The apparatus provides for improved front-to-back ratio as compared to antennas currently in use on PWD's, and therefore also reduces SAR (specific absorption rate), the level of RF energy received into the head by a PWD.

  • Patent number: 6796459
    Abstract: An automatic fill system for a beverage dispenser includes a sensor system for monitoring the beverage level in the dispenser. The sensors are wired in series with a level control board mounted inside the frame of the beverage dispenser. Sensing points are connected in an electrical circuit for maintaining the proper water to beverage concentrate ratio in the mixing hopper of the beverage dispenser. Resistance in the circuit is monitored so that when the resistance in the circuit reaches a predetermined value, a relay and solenoid open to divert water to the mixing hopper for mixing with the beverage concentrate. Sensors in the hopper shut off the dispenser when the beverage level in the hopper exceeds maximum and minimum levels.
