Abstract: Methods and circuits for distributing power to suspended-particle-device (SPD) film products including SPD windows, SPD shades, and other SPD products, which are referred to generally as SPD loads. A driving voltage derived from a primary power source is provided to an SPD load by backbone wiring which carries a low AC or DC voltage derived from the primary power source, and a conversion stage which converts the low voltage to an AC driving voltage which is then supplied to the SPD load.

Abstract: Method and apparatus for associating the color of an object with an event preferably provides linked information for the object in any one of a plurality of succeeding video frames based only on the color value of the object. Preferably, at least one computer is coupled to a GUI and to a pointing structure, and is configured to: (i) identify coordinates of the object in a first video frame where the pointing structure has pointed; (ii) determine the color values of the identified object; (iii) store the color values of the identified object; (iv) detect an action of the object being selected in any one of the plurality of succeeding video frames; (v) determine the color values of the selected object; (vi) determine whether the selected object color values correspond to the stored color values; and (vii) automatically provide the linked information to the GUI only when the color values correspond.

Abstract: A preparation combining a complex of a cancer antigen and a hydrophobized polysaccharide with an agent, e.g., an extract from hemolytic streptococcus, which binds to a Toll-like receptor to stimulate the antigen presenting cells activates all of the antigen presenting cells, the killer T cells and the helper T cells which are major immune cells when antigen specific immunity against cancer cells is induced and activated, and exerts a potent vaccinal effect. A vaccine preparation of the present invention induces immune responses to the cancer antigen, in particular, has effects of activation and induction of cytotoxic T cells and helper T cells, and thus, can be used as a therapeutic or preventive vaccine for cancer therapy.

Abstract: A first transfer mechanism of a biaxial stretch blow-forming apparatus has sliders that are transported along a circular transportation passage. The sliders slide along a circular guide rail installed on a turntable. Each of the sliders is swung to left and right by a swing arm as the turntable rotates, and a feed pitch of a preform holding groove formed in a holding plate installed at an end of each of the sliders is changed. The feed pitch can be changed by a simple mechanism. Because the holding groove always faces a radial direction, receiving and handing over actions of a preform sent along the circular transportation passage can be reliably performed.
