A vacuum seed meter for metering individual seeds at consistent intervals. The seed meter employs an improved seed disk defining a plurality of seed attachment holes for holding seeds on the disk via a vacuum attachment force. Each seed attachment hole is configured to allow a seed to be held against one side of the disk without permitting the seed to extend entirely through the attachment hole and protrude from the opposite side of the disk. In addition, the seed disk is configured to provide enhanced resistance to bending. No gaskets or brushes that maintain contact with the seed disk are required. The seed meter also employs an improved second-seed eliminator disposed alongside the seed disk. The second-seed eliminator presents a substantially smooth leading edge that is configured to contact a second seed held by an attachment hole, thereby decoupling the second seed from the disk. The second-seed eliminator can be shifted via contact with a seed firmly attached to the seed disk, thereby preventing shearing of the seed by the seed eliminator.

Scanning spot locations are generated for ablating tissue using a scanning laser beam over a treatment region by taking a target function representing a desired lens profile of ablation with a basis function representing a treatment profile produced by overlapping scanning spots in a particular treatment pattern. In some embodiments, the basis function is a two-dimensional function representing a two-dimensional section of a three-dimensional treatment profile, which has symmetry with respect to the two-dimensional section extending along the treatment pattern. For example, the treatment pattern is generally straight for myopic and hyperopic cylinders, and is generally circular for myopia and hyperopia. The fit produces ablation depths for discrete scanning spots, which are used to calculate the number of pulses at each reference position along the two-dimensional section. The pulses are distributed along the treatment pattern to produce the desired overlapping effect.

Variable bit size run length encoding (“RLE”) is used to encode uninterrupted runs of adjacent first symbols and adjacent second symbols within a sequence that may represent an image. The symbols may be 1s and 0s. The bit size used to encode a run length for a current run is varied in dependence on the bit sized used or required to encode a run length of a previous run of the same symbol type. Further, an image to be encoded may be transformed into an image / bit sequence representing changes from line to line in the image. By so transforming the image, the correlation from run length to run length of like colours is increased, thereby improving the efficiency of the variable bit size RLE.
