Title: Freely separable surgical drill guide and plate
Inventor: CESARONE D
IPC: A61B17/58
Filed: 1998-06-18
Abstract: Instrumentation for osteofixation including a locking bone plate and a surgical drill guide. The plate has a plurality of fastener holes with inner walls of a preselected hole diameter. The drill guide has a guide member, for guiding a drill bit, and a hollow collet disposed substantially coaxially with the guide member. A radially expandable forward end of the collet comprises a radially expandable neck and an outwardly projecting rim disposed forward of the neck. This rim defines a contracted outer rim diameter that is smaller than the hole diameter in a contracted collet position, and an expanded outer rim diameter that is larger than the hole diameter in an expanded position. Thus, the rim is freely extractable through the plate hole in the contracted position, but is unreceivable through the plate hole in the expanded position. The collet neck is configured and dimensioned to press outwardly against an inner wall of the plate hole when the neck is expanded.

Title: Interleaving or de-interleaving of data of variable rate
Inventor: NOKES CHRISTOPHER RYAN
IPC: G06F12/06
Filed: 2008-11-25
Granted: 2011-04-27
Abstract: An apparatus for interleaving or de-interleaving a stream of data has a memory with M serially-numbered logical memory locations. The read-address generator and write-address generator are each configured to address memory locations as a function of an increment value which itself is a function of an increment value used for a previous block of data multiplied by a dimension used for interleaving or de-interleaving the previous block. The dimension is the number of columns of data to be interleaved or de-interleaved where the number of columns is an integer factor of the number of memory locations. The use of such an increment value ensures that data elements can be read in turn from a de-interleaver for a previous block while elements from the present block are written to locations that have been used. The apparatus may be used to improve the effectiveness of forward error correction in dealing with burst errors in systems such as DVB-T2.
