Abstract: An ion mobility filter is disclosed. The present invention relates to but not exclusively a field asymmetric ion spectrometry filter. For example, we describe an ion filter for filtering ions in a gas sample. The ion filter is comprised of a plurality of electrodes, a first ion channel, and a second ion channel. The first ion channel filters ions from a target chemical in the gas sample, defines a gap between a first pair of electrodes in the plurality of electrodes, and has a first ion channel gap width. The second ion channel filters ions from the target chemical in the gas sample, defines a gap between a second pair of electrodes in the plurality of electrodes, and has a second ion channel gap width. The first ion channel gap width is greater than the second ion channel gap width.

Abstract: The waveform generator (10) comprises a switch (13). The waveform generator (10) comprises a transformer (15) having a primary side circuit and a secondary side circuit. The primary side circuit has a first terminal arranged to be conductively coupled to a DC voltage source, and a second terminal conductively coupled to the switch (13).

Each adjacent pair of electrodes defines an ion channel between them and each electrode is separate from the adjacent electrode(s).

Abstract: An apparatus and method for providing a display cell structure based on the transmissive liquid crystal technology with a useful aperture ratio even as the cell size shrinks to less than 20 microns. The invention overcomes a problem of the prior art wherein the fractional area transmitting the light of the conventional designs becomes unacceptably low due to the aperture reducing opaque storage capacitor. This reduction in aperture ratio is removed in this invention by hiding the trench capacitor below the row and column x,y lines. The cell storage capacitor is formed using a vertical trench capacitor in SOI. Although useful even in standard display sizes and configurations, the invention is particularly useful for head-mounted displays and/or optical projection displays at the UXGA form factor for both monochromatic and color displays. Alternate capacitor configurations are described.
