    摘要: A method for operating a sensor for biomolecules or charged ions, the sensor comprising a first field effect transistor (FET) and a second FET, wherein the first FET and the second FET comprise a shared node includes placing an electrolyte containing the biomolecules or charged ions on a sensing surface of the sensor, the electrolyte comprising a gate of the second FET; applying an inversion voltage to a gate of the first FET; making a first electrical connection to an unshared node of the first FET; making a second electrical connection to unshared node of the second FET; determining a change in a drain current flowing between the unshared node of the first FET and the unshared node of the second FET; and determining an amount of biomolecules or charged ions contained in the electrolyte based on the determined change in the drain current.

    摘要: Light efficient packaging configurations for LED lamps using high refractive index encapsulants. The packaging configurations including dome (bullet) shaped LED's, SMD (surface mount device) LED's and a hybrid LED type, including a dome mounted within a SMD package. In another embodiment used with SMD LED devices a relatively small semi-hemispherical “blob” of HRI encapsulant surrounds the LED chip with the remainder of the SMD cavity filled with conventional encapsulant. The packaging configurations increase the LED's light emission efficiency at a reasonable cost and in a commercially viable manner, by maximizing the light efficiency while minimizing the amount of high refractive index encapsulant used.
