An improved E-field generator including a slow-wave transmission line structure is provided herein. In some cases, the improved E-field generator may include an inductively-loaded slow-wave transmission line structure driven by a power source at one end of the structure and terminated by a load at the other end of the structure. In other cases, the improved E-field generator may include a capacitively-loaded slow-wave transmission line structure.

The same pixel stream may be displayed on an internal display and an external display while maintaining the original aspect ratio corresponding to the internal display dimensions. A connector with limited number of pins may only support a two-wire display port interface to the external display, which may not provide enough bandwidth to transmit the full resolution image to the external display. To transmit the full resolution image, a color space conversion from RGB space to YCbCr color space may be performed. The Luma component may be transmitted at full resolution, while the chroma components may be scaled. Accordingly, there is no loss of image resolution, while some amount of color resolution may be lost. However, there is no need to retime frames within the system on chip (SOC), and the same pixel stream may be used as the basis for display on both the internal and the external display.

A method and apparatus are provided for aligning optical elements or microbeads, wherein each microbead has an elongated body with a code embedded therein along a longitudinal axis thereof to be read by a code reading device. The microbeads are aligned with a positioning device so the longitudinal axis of the microbeads is positioned in a fixed orientation relative to the code reading device. The microbeads are typically cylindrically shaped glass beads between 25 and 250 microns (μm) in diameter and between 100 and 500 μm long, and have a holographic code embedded in the central region of the bead, which is used to identify it from the rest of the beads in a batch of beads with many different chemical probes. A cross reference is used to determine which probe is attached to which bead, thus allowing the researcher to correlate the chemical content on each bead with the measured fluorescence signal. Because the code consists of a diffraction grating typically disposed along an axis, there is a particular alignment required between the incident readout laser beam and the readout detector in two of the three rotational axes. The third axis, rotation about the center axis of the cylinder, is azimuthally symmetric and therefore does not require alignment.
