Wise Adrian Philip, Robbins William Philip, Sotheran Martin William: Data pipeline system and data encoding method.. Pioneer Digital Design Centre, January 5, 1994: EP0576749-A1 (78 worldwide citation)

A pipeline structure processes data in a series of stages, each of which has a data input latch (LDIN) and passes it on to the next stage in the pipeline via a data output latch (LDOUT). The stages are preferably connected to two non-overlapping clock phases (PH0, PH1). Adjacent stages are also conn ...

Roy Apurba: Partial gap magnetic core apparatus.. American Telephone & Telegraph, January 5, 1994: EP0577334-A2 (68 worldwide citation)

Potted wire-wound loop-core structures are based on cores which include partial gapped inductors or transformers with their reduced dependence of inductance on current during operation. Total enclosure of gaps by encircling core material is both magnetic and physical, thereby avoiding fringing magne ...
