The method can further be used to design and construct NMPV pumps significantly smaller in size than those currently available to the art without significant loss in pump performance.1 aForster, Fred, K.1 aBardell, Ron, L.1 aSharma, Nigel, R.  uhttp://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=16&f=G&l=50&co1=AND&d=PTXT&s1=%22Bardell%3B+Ron%22.INNM.&OS=IN/%22Bardell;+Ron%22&RS=IN/%22Bardell;+Ron%2201039nas a2200157   4500008004100000245007100041210006200112260000800174520035600182100002200538700002400560700002400584700002700608700002200635856022400657       1999                        eng d00aUnited {States} {Patent}: 5876187 - {Micropumps} with fixed valves0 aUnited States Patent 5876187 Micropumps with fixed valves  cmar3 aMicropumps fabricated by micromachining techniques and employing fixed or no-moving-parts valves. As one aspect of the invention, a laser-assisted chemical etching technique is employed for providing smooth-walled, curved configuration necessary to obtain the desired flow characteristics of the valves that are used in conjunction with the micropump.1 aForster, Fred, K.1 aBardell, Ronald, L.1 aBlanchard, Alan, P.1 aAfromowitz, Martin, A.1 aSharma, Nigel, R.  uhttp://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=4&f=G&l=50&co1=AND&d=PTXT&s1=%22Sharma%3B+Nigel%22.INNM.&OS=IN/%22Sharma;+Nigel%22&RS=IN/%22Sharma;+Nigel%22
