  • Publication number: 20160115720
    Abstract: An interconnected lock for use on a door, where the lock has adjustable offset spacing between a deadbolt and latchbolt. The lock includes first and second shafts for actuating the deadbolt lock mechanism, at different offset spacings. A linkage arm connected to and moveable by the latchbolt actuator is alternately connectable to rotate either the first or second deadbolt-actuating shaft. The linkage arm has first and second upper positions, for alternate connection to rotate the first and second deadbolt-actuating shafts, respectively. Upon operation of the interior actuator, the linkage arm moves the deadbolt along the second axis from the latched to the unlatched position at the same time that the operation of the interior actuator moves the latchbolt along the first axis from the latched to the unlatched position.

  • Publication number: 20160114098
    Abstract: A drive mechanism for a medication delivery device includes a motor, a housing, a gear cover, a gear transmission system, a helical transmission system, and a sensor system. The helical transmission system includes a plug, a screw shaft, and a sliding block connecting the plug to the screw shaft. The gear transmission system includes a first gear disposed on an output shaft of the motor and a second gear disposed on one end of the screw shaft. Dual gears interconnect the first and second gears.

  • Publication number: 20160115468
    Abstract: The present invention provides a pharmaceutical composition containing albumin-binding arginine deiminase (AAD) fusion protein for treating cancer or other arginine-dependent diseases. The AAD fusion protein can be purified from both soluble and insoluble fractions of crude proteins, it binds to human serum albumin (HSA) or animal serum albumin and has its high activity with longer half life for efficient depletion of arginine in cancer cells. The specific activities of wild-type ADI and AAD fusion protein in the present invention are about 20 and about 19 U/mg (at physiological pH 7.4), respectively. The AAD fusion protein used in the present invention can be used in the treatment of various cancers (e.g. pancreatic cancer, leukemia, melanoma, head and neck cancer, colorectal cancer, lung cancer, breast cancer, liver cancer, nasopharyngeal cancer, esophageal cancer, prostate cancer, stomach cancer & brain cancer) and curing arginine-dependent diseases.

  • Patent number: 9323218
    Abstract: Techniques for efficiently generating full parallax 3-D holographic images of a 3-D real or synthetic object scene are presented. A holographic generator component (HGC) can receive a real object scene or generate a synthetic object scene. The HGC can downsample the scene by a defined downsampling factor and generate, from the downsampled scene, an intermediate object wavefront recording plane (WRP) that can be placed in close proximity to the scene. The HGC can expand and interpolate the WRP to generate the holographic images. The HGC can decompose a scene into polyphase image components (PICs), generate a WRP for the image components, sum the WRP of the PICs, and expand and interpolate the WRP to generate holographic images of the scene. The HGC can utilize look-up tables to store and use wavefront patterns of each region of an image to facilitate reducing computational operations in generating the holographic images.
