  • Publication number: 20160279958
    Abstract: A liquid cartridge is configured to be inserted into a liquid consuming apparatus in a first direction along a horizontal direction against an urging force directed in a second direction opposite the first direction, and thereby to be mounted to the liquid consuming apparatus. The liquid cartridge is configured to pivot about a pivot center in the liquid consuming apparatus. The liquid cartridge includes a rear face, and the rear face includes a first portion and a second portion positioned further in an upward direction than the first portion. The first portion includes a portion positioned further in a downward direction than the pivot center, and the first portion is positioned further in the first direction than the second portion.

  • Publication number: 20160279952
    Abstract: A liquid cartridge is configured to be inserted into a liquid consuming apparatus in a first direction along a horizontal direction against an urging force directed in a second direction opposite the first direction, and thereby to be mounted to the liquid consuming apparatus. The liquid cartridge includes a lock surface and an operation portion. The liquid cartridge is configured to pivot between a first attitude and a second attitude. When the liquid cartridge is in the first attitude, the lock surface contacts a lock portion of the liquid consuming apparatus in the second direction, and the operation surface faces an upward direction and the second direction. When the liquid cartridge is in the second attitude, the lock surface is positioned further in a downward direction than the lock portion.

  • Patent number: 9155139
    Abstract: An LED driver circuit that can regulate the input signal voltage so that the driver circuit can be used over wide input voltage range or at predetermined voltages. Discrete components are used to drive an LED array with a constant current. The LED driver circuit includes a dynamic current regulator. The dynamic current regulator includes a resistor and capacitor in parallel to provide dynamic current regulation to a switching mode power supply circuit that controls the LED illumination.

  • Publication number: 20150198316
    Abstract: A function generator is introduced into a stack light in the form of a compatible modular element that fits between the base and a light module. By centralizing the operation of the function generator, fewer components must be separately stocked and a cost savings may be realized through the centralized function generator.

  • Publication number: 20150198317
    Abstract: A power converter is introduced into a stack light in the form of a compatible modular element that fits between the base and a light module. By converting multiple input voltages to a common core voltage in a module distinct from the base and light modules, proliferation of different varieties of base modules and light modules may be reduced without impact on customer selection.

  • Publication number: 20130259809
    Abstract: A process of using Isatis root polysaccharide in the manufacture of medicaments for treating and/or preventing diseases induced by influenza virus and complications thereof, wherein the molecular weight of the Isatis root polysaccharide is 3000-7000 Da, and the influenza viruses include influenza virus A, influenza virus B, avian influenza virus, such as human influenza virus H1N1, H3N2, avian influenza virus H6N2, H7N3, H9N2 and INF B. The mechanism of the Isatis root polysaccharide against influenza virus is due to the ability to inhibit the attachment of influenza virus to the host cell. The present invention also discloses a pharmaceutical composition containing the above-mentioned Isatis root polysaccharides and a method for preparing the polysaccharides.

  • Patent number: 8225677
    Abstract: A capacitive sensor for measuring flow parameters of a two-phase flow, a device for measuring phase concentration of a two-phase flow, and a system and method for measuring flow parameters of a two-phase flow is disclosed. In the capacitive sensor, at least one pair of electrodes is twisted by 180° in a common direction into a spiral shape. Edge guard electrodes are twisted in the common direction and are formed between adjacent electrode edges. Problems of non-homogeneous sensitivity distribution of a measuring field and soft field effect can be effectively addressed, thereby allowing reliable and accurate measurement of phase concentration of a two-phase flow. The system for measuring flow parameters of the two-phase flow can output signals with a current of 4˜20 mA to a PLC system or communicate with an industrial process control computer or with a remote control computer system in a operating room.
