Abstract: Tuning assemblies for stringed musical instruments are provided. One implementation of a tuning assembly includes a housing that includes a plurality of worm wheel chambers, a plurality of worm shaft chambers, and a plurality of string slots. The tuning assembly may also include a plurality of worm wheels configured to reside within the worm wheel chambers of the housing. Each worm wheel may be configured to rotate about a longitudinal axis thereof. Also, each worm wheel may include a first worm gear and a string anchor through-hole. The tuning assembly may also include a plurality of worm shafts configured to reside within the worm shaft chambers of the housing. Each worm shaft may be configured to rotate about a longitudinal axis thereof and may include a second worm gear, which may be configured for engagement with the first worm gear to enable tuning of the strings of an instrument.

Abstract: Systems and methods are provided for shielding integrated circuits from electromagnetic or electrostatic fields by locating an active device layer between two conductors that are electrically coupled together. In certain embodiments, a sensor comprises a conductive substrate that provides structural support and shielding to circuit elements in a semiconductor device layer. The device layer is between the conductive substrate and a shield layer that are electrically coupled together to create a shield or “Faraday box.” In certain embodiments, the device layer is substantially isolated from the conductive substrate and the shield layer by insulative layers. In certain embodiments, an input voltage powers the device layer and is also coupled to the substrate and the shield layer. Thus, the conductive substrate and the shield layer absorb and/or repel electrostatic charges or ions in a medium surrounding the sensor.

Abstract: A process and apparatus to deliver both process chemical and solvent for cleaning the process chemical in a solvent purge refill system along with an integral solvent sorption module, in a single “assembly” that permits ease of shipping, minimal end-user interaction, sufficient solvent for the solvent purge operation, without residual solvent, requiring disposal. This eliminates customer handling of the solvent, and eliminates the customer's need to find a solvent waste facility, as residual solvent can be returned in the same package in one piece/one step.
