  • Patent number: 10642163
    Abstract: A system and method for controlling an exposure dose of a light source are disclosed. The system includes an LED light source, a light homogenizer, an energy detection unit and an exposure dose control unit coupled to both the LED light source and the energy detection unit. The energy detection unit includes an energy detector corresponding to the LED light source or the light homogenizer and an energy spot sensor corresponding to a wafer. By using the LED light source capable of producing UV light in lieu of an existing mercury lamp, the system is less hazardous and safer by eliminating the risk of discharging hazardous mercury vapor into the environment when the mercury lamp is broken. Moreover, exposure illuminance of the LED light source can be adjusted and the LED light source can be turned on/off under the control of exposure dose control unit to expose the wafer with high dose control accuracy, without needing to use a variable attenuator or an exposure shutter.

  • Patent number: 9848285
    Abstract: A Bluetooth communication method and a device including a Bluetooth module to perform the method are provided. In the method: the device is renamed so that a name of the device includes a character string. The Bluetooth module searches for a second device whose name includes the same character string or a corresponding character string. The Bluetooth module establishes a connection between the device and the second device. The device transmits data with the second device using the established the connection.

  • Publication number: 20140348781
    Abstract: In certain embodiments, this disclosure relates to conjugates comprising GM-CSF and IL-9 and uses related thereto, e.g., enhancing the adaptive immune system. Typically the GM-CSF and IL-9 are connected by a polymer linker, e.g., polypeptide. In certain embodiments, the disclosure relates to nucleic acids encoding these polypeptide conjugates, vectors comprising nucleic acid encoding polypeptide conjugates, and protein expression systems comprising these vectors such as infectious viral particles and host cells comprising such a nucleic acids.
