Abstract: An integrated mesopump-sensor (300, 320) suitable for disposition in two- an d three-dimensional arrays having small dimensions is disclosed. One mesopump (30, 320) is formed of an electrostatically attractable flexible diaphragm (70, 240) disposed through cavities or pumping chambers (64) formed between two opposing electrostatically chargeable material layers (72, 74). Fluid is  pumped through the chambers by sequentially moving the diaphragm (70, 240) toward the first chargeable layer (72), then towards the second chargeable layer (74), which can pull and push the fluid through a series of chambers (64, 132, 134, 136), and past the sensor (303, 354, 422, 502). One group of sensors utilizes multiple and varied chemoresistive sensors which can vary i n resistance differently in response to the presence of various analytes. Another group of sensors utilzes chemo-fluorescent sensors (502, 506) that fluoresce in the presence of particular analytes. Some mesopump-sensor syste ms (600) can be manufactured using MEMS technology and can be coupled to controllers (602) for sequencing the pumps (60) and analyzing sensor outputs  using methods including Principle Component Analysis.

Title: Antenna systems with common overhead for cdma base stations
Inventor: MCGOWAN NEIL N
IPC: H04J99/00
Filed: 2001-11-29
Abstract: Antenna systems are used for transmitting common overhead channels (pilot, sync, and paging channels) over a whole sector while transmitting and receiving unique traffic channels on individual beams in the sector. Each beam in the sector is transmitted at a frequency offset from other beams in the sector. The offset frequency is chosen such that the effect of cancellation of the pilot channel caused by the summing of signals from multiple beams is minimized. Alternative, each beam in the sector can have a time dependent phase offset relative to each other to minimize the effect of cancellation of the pilot channel caused by the summing of signals from multiple beams. System capacity is substantially increased since the number of traffic carrying beams per sector is increased without using more pilot channel PN offsets. Beams are fixed and the same antennas are used for the overhead channels as the traffic channels, obviating the need for complex algorithms and calibration procedures.
