  • Patent number: 11196282
    Abstract: An emergency lighting assembly is provided having a housing with one or more adjustable lamp assemblies for aiming the light at selected areas. The lamp assembly is mounted in the housing by a ball and socket arrangement. The lamp assembly has a substantially spherical shape with a front section made of a heat conducting material and a rear section made of a plastic material. The front section has an opening on a front side having a lens and a base spaced from the front side supporting the light source. The light source in one embodiment is an LED which is coupled to the front section to conduct heat from the LED away from the LED and the housing. The rear section has an opening in the rear side that receives a fixed stop member to limit pivoting movement of the lamp assembly with respect to the housing. The rear section also includes a projection oriented to contact the stop member to limit rotation of the lamp assembly with respect to the housing.

  • Patent number: 11103571
    Abstract: In the invention described here, the approach is to formulate an edible vaccine based on N-terminal yeast surface display expression systems including S. cerevisiae EBY100/pYD5-VP28, S. cerevisiae EBY100/pYD5-VP28-VP24 and S. cerevisiae EBY100/pYD5-VP24 for preventing shrimps such as L. vannamei, P. monodon and M. rosenbergii species from white spot syndrome virus (WSSV) infection, suggesting that yeast surface display expression system expressing WSSV antigen has potential as a prophylactic treatment for WSSV in shrimps via oral vaccination. The technology developed in this patent application can also be used to produce edible (oral) vaccines for preventing and treating other infectious diseases in animals and human.

  • Patent number: 8865335
    Abstract: An electrochemical storage cell is disclosed that comprises a cathode sheet, an anode sheet, and a separator sheet between the cathode and anode sheets. A metal foil current collector extends from a longitudinal edge of the cathode sheet. A further metal foil current collector extends from a longitudinal edge of the anode sheet. The anode sheet, cathode sheet, and separator sheet are wound in a flattened coil shape to produce a core in which the metal foil current collector of the cathode sheet extends beyond the separator sheet at one end of the core and the metal current collector of the anode sheet extends beyond the separator sheet at an opposite end of the core. Overlying layers of the metal foil current collector of the cathode sheet are compressed together and placed in electrical communication with a positive terminal of the cell while overlying layers of the metal foil current collector of the anode sheet are compressed together and placed in electrical communication a negative terminal of the cell.

  • Patent number: 8092936
    Abstract: There is disclosed a core for an electrochemical cell that comprises an anode sheet, a cathode sheet, and a separator sheet disposed between the anode sheet and cathode sheet. The anode sheet, cathode sheet, and separator sheet are wound to form a flattened coil structure. The flattened coil structure has opposed flattened sides and opposed arcuate sides. The anode and cathode sheets terminate at the same or different arcuate sides. Further, the separator sheet may terminate at one of the arcuate sides.
