  • Patent number: 11966081
    Abstract: An optical subassembly for non-reciprocal coupling of light from a planar optical waveguide output outside the optical subassembly to an optical fiber includes a carrier configured to support the optical subassembly, an optical fiber fixed to the optical subassembly, a focusing optical system consisting two foci with one focus coincident with the input of optical fiber, an optical isolator to transmit light unidirectionally between two foci, an input boundary provided by the carrier to align the optical subassembly with the planar optical waveguide output. In particular, the optical subassembly is operably configured to provide a low transmission loss for light traveling from the planar optical waveguide output to the optical fiber.

  • Publication number: 20160294272
    Abstract: A vibration electric generator includes two generator units connected with each other in a lever manner. Each generator unit includes: a moving part configured to move in a linear manner; a permanent magnet attached to the moving part, the permanent magnet being configured to provide a magnetic field; a fixed stator including a plurality of windings; and a cushion made from an impact absorber and installed at each end of the moving part. Due to a vibration motion of a first frequency, the stator is configured to also move in the first frequency. The moving part is configured to move in a second frequency that is different from the first frequency.

  • Patent number: 9347107
    Abstract: An expression vector is provided. The vector includes a promoter configured to drive the expression of the transgene in the cell. The vector also includes a tag sequence encoding a tag peptide directing the protein of the expressed transgene to a pre-determined location. The vector further includes a cleavage sequence encoding a peptide that is recognizable by a protease and a marker gene configured to encoding a protein to indicate the expression of the transgene.

  • Publication number: 20120096885
    Abstract: A solar powered vehicle air-conditioning system for air conditioning a vehicle includes an air conditioning subsystem and a solar power subsystem. The air conditioning subsystem includes a compressor, a condenser, an evaporator and a plurality of valves and sensors, and is configured for air conditioning the vehicle. The solar power subsystem includes a solar photovoltaic module configured for generating electric power when being illuminated by sunlight, a battery module configured for providing electric power to the air conditioning subsystem, and a solar power control module configured for receiving the electric power from the solar photovoltaic module and charging the battery module thereby. The solar power control module is configured to regulate the charging current flowing from the solar power control module to the battery module to be equal to or less than a predetermined current value.

  • Patent number: 6290978
    Abstract: Derivatized Arabinogalactan can be utilized in a variety of compositions to impart functionality without imparting negative rheological affects when the amount of the derivatized Arabinogalactan is increased in the composition. This is particularly important in the personal care industry, where it is desirable to have the flexibility to adjust the amount of derivatized Arabinogalactan depending upon the results it is desired to deliver to the user without negatively impacting the overall viscosity of the personal care composition.
