摘要:
A radiation-emitting device includes a nanowire that is structurally and electrically coupled to a first electrode and a second electrode. The nanowire includes a double-heterostructure semiconductor device configured to emit electromagnetic radiation when a voltage is applied between the electrodes. A device includes a nanowire having an active longitudinal segment selectively disposed at a predetermined location within a resonant cavity that is configured to resonate at least one wavelength of electromagnetic radiation emitted by the segment within a range extending from about 300 nanometers to about 2,000 nanometers. Active nanoparticles are precisely positioned in resonant cavities by growing segments of nanowires at known growth rates for selected amounts of time.

An artificial insemination apparatus for insertion into a cervix of a sow, including a tubular passage member which is helically coiled at a distal end. The helically coiled distal end terminates in an open tip including an opening communicating with a bore of the tubing. The helically coiled distal end is inserted into and is secured by the muscular folds in the cervix, and semen is transmitted therethrough.

A reflector comprises a core and a first dielectric mirror formed over at least a portion of the core to reflect light having a preselected wavelength. The reflector may comprise a plurality of dielectric mirrors formed concentrically over the first dielectric mirror to reflect light having the preselected wavelength. The multiple dielectric mirrors may have different diffraction indices. A layer of such reflectors deposited onto the reflective surface of a projection screen may enhance the reflective selectivity of the screen to the preselected wavelength. Reflectors formed to reflect different wavelengths may be deposited onto the reflective surface to enhance selectivity to the different wavelengths and minimize reflection of ambient light.

A protected dual purpose power/enter switch for an integrated receiver/decoder has a first relay and a second relay adapted for operative communication with a motherboard and with each other. A switch and a processor are in operative communication with the first relay. When the device is off, said switch is configured to activate the first and second relay to power up the device, and when said device is on, the first relay connects the switch to the processor as an enter switch. The switch may power off said device by entering a power off menu item displayed by said processor.

摘要:
A method, system, apparatus, and computer program product is presented for improving the execution performance of flow-based-program (FBP) programs and improving the execution performance further on systems with additional processing resources (scalability). A FBP supervisor is inserted as the initial executable program, which program will interrogate the features of the operating system upon which it is executing including but not limited to number of processors, memory capacity, auxiliary memory capacity (paging dataset size), and networking capabilities. The supervisor will create an optimum number of processing environments (e.g. threads in a Windows environment) to service the user FBP application. The supervisor will further expose other services to the FBP application which improve the concurrent execution of the work granules (processes) within that FBP application. The supervisor further improves the generation and logging of messages through structured message libraries which are extended to the application programmer. The overall supervisor design maximizes concurrency, eliminates unnecessary work, and offers services so a process should suspend rather than block.
