Abstract: The present invention is a pickup system including a transducer, a mount, and a cartridge for modifying perceived sound from a musical instrument. The transducer includes a housing, a magnet and an electric signal carrier. The mount attaches the transducer to the instrument. The cartridge includes a container and attachment device, which positions the container in proximity to the transducer. The attachment device engages the container with the transducer so as to affect the electric signal created by the instrument. The cartridges and container can be either integral or interchangeable to vary resonance materials to the transducer. The container may be filled with another material, including ferromagnetic fluid for an induced magnet effect upon the perceived sound from the transducer.

Abstract: Embodiments in accordance with the present invention provide for a palladium complex characterized by the general formula: where A is a bidentate monoanionic ligand, NHC is a nucleophilic heterocyclic carbene, and Z is an anionic ligand. Such palladium complexes are useful in initiating cross-coupling reactions.

Abstract: A synthetic method leading to the isolation of ruthenium-based olefin metathesis catalysts relies on the cross metathesis reaction between (L1)Ru(L2)(3-phenylindenylid-1-ene)Cl2 (where L1 and L2 can be two-electron donors) and an olefin. This method leads to the isolation of numerous ruthenium olefin metathesis catalysts.

Abstract: An interconnection device has a multiplicity of individual arms attached to a carrier board. The carrier board includes vias which go through the board and have a pad on the top and bottom of the board near the via. Attached to each via pad is an arm. The arm is attached so that its free end extends out over the clearance hole in the carrier board. The free end of the arm positioned over the clearance hole includes a surface treatment which allows the free end to make good electrical contact with a mating device. Each of the arms is positioned so that it corresponds to the pads on the device to which it will connect. Each of the arms acts as a cantilevered beam. The arms are deflected. The geometry, material, material temper, and surface plating allow for a very low overall force having to be applied to the interconnection in order to provide good electrical contact between the first module and second module being interconnected. The amount of compliance may be 10 to 12 mils.
