摘要： A light having a plurality of LEDs and a switching substrate is disclosed. The switching substrate is coupled to LEDs and includes a plurality of switches that provide a plurality of configurations for the LEDs. Each configuration is characterized by a two-dimensional array of LEDs having a minimum bias potential and a maximum bias potential, the LED array generating light when a bias potential is provided between the power terminals that is greater than the minimum bias potential, at least two configurations being operable to provide light at bias potential within this range. The switching substrate is sub-dividable into a plurality of identical multi-LED light sources by dividing the switching substrate along predetermined lines. The array of LEDs can be organized as a nested array of LEDs. The switches can be implemented as passive switches that are set by removing portions of conductors or bridging gaps in conductors.

摘要： A memory constructed from a plurality of capacitor elements organized into a two-dimensional array having a plurality of rows and columns. Each capacitor element includes a bottom electrode, a top electrode, and a dielectric layer disposed between the top and bottom electrodes, all of the bottom electrodes in each column being connected together to form a column electrode and all of the top electrodes in each row being connected together to form a row electrode. The memory is read by generating an electrical signal on one of the row electrodes while connecting the remaining row electrodes to a reference potential and sensing the current generated in one of the column electrodes. The capacitance of the capacitor elements corresponds to data values stored in the memory. Different capacitor values may be constructed by altering the area of the top electrodes or altering the dielectric constant of the dielectric layer between the corresponding top and bottom electrodes. The area of the top electrodes may be set to a first value during fabrication and then altered after fabrication of the basic structure. In this manner, a write-once-read-many (WORM) memory may be implemented.

摘要： A method is described for cloning filamentous microorganisms wherein the microorganisms are suspended in a liquid media and fragmented to produce a substantial increase in the number of viable filaments which are less than a predetermined size. Those filaments which are less than the predetermined size are then separated from the balance of the suspension of filaments by filtering.

Each LED has surface mount contacts on a first surface thereof and emits light from a second surface thereof that is opposite the first surface. The mounting substrate includes a top surface having a plurality of connection traces. Each connection trace includes an n-trace positioned to underlie a corresponding one of the n-contacts and a p-trace positioned to underlie a corresponding one of the p-contacts, the p-trace having an area greater than the p-contact.

摘要： A method for detecting the presence of target molecules bound to a working electrode in a first location. The first location is coated with a detection solution containing labeling molecules that include a first charge-separation moiety attached to a first molecule that binds to the target molecule. The first charge-separation moiety includes a material that generates hole-electron pairs in response to being illuminated by light in a first band of wavelengths. After removing any unbound labeling, the working electrode is immersed in a solution containing a compound that is oxidized by the generated holes. The first location is then selectively illuminated with light in the first band; and the change in the current and/or potential is measured between the working electrode and a reference electrode in contact with the solution. The first charge-separation moiety is preferably constructed from particles of a semiconducting material such as TiO2.
