Specific ionic interactions with a sensing material that is electrically coupled with the floating gate of a floating gate-based ion sensitive field effect transistor (FGISFET) may be used to sense a target material. For example, an FGISFET can use (e.g., previously demonstrated) ionic interaction-b ...

Hung Hsiang Jonathan Chao, Yau Ren Jenq: Methods and apparatus for fairly scheduling queued packets using a ram-based search engine. Polytechnic University, John C Pokotylo, Straub & Pokotylo, May 14, 2002: US06389031 (86 worldwide citation)

A hierarchical searching technique is used to find the first memory location of a calendar queue with a validity bit of “1” (that is, the lowest time stamp). The bit string at any level l (l≠0) can be stored in a RAM of size g

Hung Hsiang Jonathan Chao, Alper Altinordu: Methods and apparatus for providing a fast ring reservation arbitration. Polytechnic University, John C Pokotylo, Straub & Pokotylo, September 10, 2002: US06449283 (85 worldwide citation)

In a switch having input ports and output ports, a fast ring reservation arbitration is provided by grouping crosspoint units associated with an output port. If any of the crosspoint units of a group request the output port, a received token will be passed to crosspoint units within the group. If, o ...
