Abstract: A Universal Serial Bus (USB) dongle may include an optical transceiver having a USB interface for engagement to an electronic device such as a laptop computer or other USB-configured device. The USB dongle may include a converter or buffering, isolation, modulation or amplification circuitry. The USB dongle sends and receives data signals which may be carried upon an optical transmission as generated by an LED light source which in turn is in communication with a host device such as a network processor. The USB dongle may also include operational amplifiers (op-amps) and transistor amplifiers.

Abstract: This invention relates to methods of using weak partitioning chromatography for the purification of a product from a load fluid containing one or more impurities. Further, the invention relates to methods of weak partitioning chromatography defined by operating conditions which cause a medium to bind least 1 mg of product per mL of medium, or alternatively, defined by a partition coefficient of at least 0.1.

Abstract: An LED light and communication system includes at least one optical transceiver, the optical transceiver including a light support and a processor. The light support has a plurality of light emitting diodes and at least one photodetector attached thereto, the light emitting diodes receiving power from a power source. The processor is in communication with the light emitting diodes and the at least one photodetector, the processor capable of illuminating the light emitting diodes to simultaneously create at least one first light signal, and at least one second light signal, the first light signal being observable to the unaided eyes of an individual and the second light signal not being observable to the unaided eyes of the individual. The second light signal includes at least one data packet. The at least one data packet comprises global positioning system (GPS) location information.
