Abstract: The detection and correction of errors in digital data transmitted by or stored in a media channel is provided by processing the data through a triple orthogonally interleaved error correction system. On the transmit/store side of the system, the data is encoded three times prior to placement in the media channel with two different interleaving steps performed between the encoding steps. The first interleave is an orthogonal row shuffling interleave that provides enhanced protection against burst errors. On the receive/play back side, the data is decoded and deinterleaved, with included errors detected and corrected to enable recovery of the original data. To enhance the error correction, a circuit is used for generating a symbol accurate error flag identifying symbols containing errors thereby allowing the error correcting decoders to focus on and correct the data.

Abstract: A workpiece such as an electronic component, comprising a body and leads that project in one direction from the body, has its body coated by immersing it in a fluidized bed while the workpiece is vibrated. Immersion depth is such that the uppermost surface of the body is at or just slightly below the top surface of the fluidized bed. Vibration of the workpiece during immersion ensures a uniform thickness coating all over the body and prevents "pants legs" on the leads.
