Abstract: A plating system comprises a plating solution and an apparatus for control of the plating solution, the apparatus including a Raman spectrometer for measurement of organic components, a visible light spectrometer for measurement of metallic components, and a pH probe. The plating solution can be sampled continuously or at intervals. Dosing of the plating solution adjusts for components consumed or lost in the plating process. The method of dosing is based on maintaining a desired composition of the plating solution.

Abstract: A transmitter system that transfers digital data on a fixed frequency channel of a radio frequency band in the presence of interference from at least one FHSS interference source includes a time diversity generation circuit. The time diversity circuit compacts a duration of data frames then replicate the time compressed data frames. The duplicated time compressed frames of data are transmitted to a communication receiver that has a time diversity data recovery circuit.

Abstract: A communication system that transfers digital data on a fixed frequency channel of a radio frequency band in the presence of interference from at least one FHSS interference source includes a time diversity generation circuit. The time diversity circuit compacts a duration of data frames then replicate the time compressed data frames. The duplicated time compressed frames of data are transmitted to a communication receiver that has a time diversity data recovery circuit. The time diversity data recovery circuit buffers the received compressed and replicated data frames, evaluates whether each of the duplicated time compressed data frames are received correctly. If any one of the duplicated time compressed data frames is destroyed, the copy of the destroyed duplicated time compressed data frame is used to recover the data frame.

Abstract: A receiver system that receives and recovers digital data on a fixed frequency channel of a radio frequency band in the presence of interference from at least one FHSS interference source. The digital data has a duration of data frames compacted then replicated to form duplicated time compressed data frames. The duplicated time compressed frames of data are transmitted to a communication receiver that has a time diversity data recovery circuit. The time diversity data recovery circuit buffers the received compressed and replicated data frames, evaluates whether each of the duplicated time compressed data frames are received correctly. If any one of the duplicated time compressed data frames is destroyed, the copy of the destroyed duplicated time compressed data frame is used to recover the data frame.

Abstract: An enclosure system for a device includes an enclosure having an outer surface and an inner surface. The system includes an aperture that extends between the outer surface and the inner surface of the enclosure. The aperture has a larger cross-section adjacent the outer surface than adjacent the inner surface. A filter is positioned within the aperture.
