Andrew P DeJaco, William R Gardner: Encoding rate selection in a variable rate vocoder. Qualcomm Incorporated, Russell B Miller, Sean English, Linli L Golden, April 21, 1998: US05742734 (43 worldwide citation)

It is a first objective of the present invention to provide a method by which to reduce the probability of coding low energy unvoiced speech as background noise. The present invention determines an encoding rate by examining subbands of the input signal, by this method unvoiced speech can be disting ...

William R Gardner: Method for producing nozzles for ink jet printers. Xerox Corporation, January 20, 1981: US04246076 (39 worldwide citation)

A divergent ink jet nozzle array is made by forming by photochemical means suitably shaped polymeric posts on a conductive substrate, then electroplating a metallic material around the posts. The metallic material is stripped from the substrate, and the posts dissolved providing a well-defined ink j ...
