Abstract: The prosthesis of the invention are configured such that the average thickness of the shell in the region where the posterior and anterior faces meet is greater, e.g., at least twice, the average thickness of the shell in the region of the anterior face. This reinforcement can reduce or eliminate undesirable scalloping effects along the upper perimeter of the prosthesis that can otherwise occur when gravity pulls downward on a filled prosthesis. Moreover, because the reinforcement is preferably confined to a radius/posterior region extending at least part of the way around the perimeter of the prosthesis, it is possible for the shell of the prosthesis in nearly the entire anterior face of the prosthesis to be formed of relatively thin material. This preserves a natural appearance of the prosthesis when it is implanted.

Abstract: An integrated network switch operable in either full-frame or half-frame switching modes on a circuit-by-circuit basis. To effect selective operation in either full-frame or half-frame switching modes, an information memory buffer has the capacity of storing two samples per port. A connection memory contains the source addresses for the output ports. The most significant bit of an address designates the first or second sample of the two sample information memory buffer. For half-frame mode operation, the current value of the most significant bit of the write pointer (the address being written to) is used in the source address for reading when the source address is less than the write pointer. However, when the source address is greater than the write pointer, the most significant bit position is switched. For full-frame mode operation, the most significant bit of the source address will always take the inverse of the most significant bit for the write pointer.
