Abstract: Spectral optical imaging at one or more key water absorption fingerprint wavelengths measures the difference in water content between a region of cancerous or precancerous tissue and a region of normal tissue. Water content is an important diagnostic parameter because cancerous and precancerous tissues have different water content than normal tissues. Key water absorption wavelengths include at least one of 980 nanometers (nm), 1195 nm, 1456 nm, 1944 nm, 2880 nm to 3360 nm, and 4720 nm. In the range of 400 nm to 6000 nm, one or more points of negligible water absorption are used as reference points for a comparison with one or more key neighboring water absorption wavelengths. Different images are generated using at least two wavelengths, including a water absorption wavelength and a negligible water absorption wavelength, to yield diagnostic information relevant for classifying a tissue region as cancerous, precancerous, or normal.

Abstract: A high-power solid-state transistor structure comprised of a plurality of emitter or gate fingers arranged in a uniform or non-uniform manner to provide improved high power performance is disclosed. Each of the fingers is associated with a corresponding one of a plurality of sub-cells. In an exemplary embodiment, the fingers may be arranged in a 1-D or 2-D form having a “hollow-center” layout where one or more elongated emitter fingers or subcells are left out during design or disconnected during manufacture. In another exemplary embodiment, the fingers may be arranged in a 1-D or 2-D form having one or more “arc-shaped” rows that includes one or more elongated emitter fingers or subcells. The structure can be practically implemented and the absolute thermal stability can be maintained for very high power transistors with reduced adverse effects due to random variation in the manufacturing and design process.

Abstract: A serpentine guard trace for reducing far-end crosstalk of a micro strip transmission line is provided. The serpentine guard trace reduces receiving-end crosstalk caused by an electromagnetic interference of a signal of a nearby transmission line when transmitting a high speed signal through a micro strip transmission line on a printed circuit board. The serpentine guard trace is located between two nearby transmission lines and has a line width narrower than that of transmission lines for an effective serpentine structure. A characteristic impedance of the serpentine guard trace increases due to the narrow line width. Termination resistors having impedance which is the same as the characteristic impedance of the serpentine guard trace are located on both ends of the guard trace to minimize a reflection wave generated in the serpentine guard trace. The receiving-end crosstalk can be effectively reduced by using the serpentine guard trace instead of a linear guard trace.
