Abstract: A shutter device includes a light blocking unit and a voice coil motor. The voice coil motor includes a permanent magnet module, a guide track assembly and a coil assembly. The coil assembly is arranged on the guide track assembly, and the permanent magnet module is adapted to produce a magnetic field in the guide track assembly. The light blocking unit includes two shutter blades both connecting to the coil assembly. When energized, the coil assembly will produce a magnetic field having a direction same as or opposite to the direction of the magnetic field in the guide track assembly so that the coil assembly moves forward or backward along the guide track assembly to drive the two shutter blades to open or close. A method controls the shutter device. An exposure dose control method is used with a photolithography machine including the shutter device.

Abstract: The present invention provides a wavelength control method, a system thereof and a shutoff depth control circuit. The method includes: enabling a current temperature of TEC (6) to be rapidly stabilized at a target temperature through a closed loop control of hardware PID (8); allowing the shut-off depth control circuit (11) to operate when a burst driver (5) that drives a light emitting assembly (3) is standby or operating, providing an input to the light emitting assembly (3) through the shut-off depth control circuit (11) so that the light-emitting assembly (3) can emit the light that does not affect the normal operations of other ONU, the light emitted allows the light emitting assembly (3) to be warmed up, which enables the light emitting assembly (3) to quickly stabilize the emitted light within the bandwidth required by each channel of the system during the time period from a non-light emitting state to a light emitting state.

Abstract: The present specification describes an adaptive resource allocation method and apparatus. One example method includes determining a request time, an execution time, and a response time corresponding to a service statement executed by the database system during a time period, wherein the request time is a time at which the service statement was executed by the database system, the execution time is an amount of time allocated for execution of the service statement by the database system, and the response time is an amount of time that elapsed between the request time and a time at which execution of the service statement ended; identifying a time segment of the time period based on the request time; determining a service type associated with the service statement; and updating a resource quota for the time segment based on the service type, the execution time, and the response time for the service statement.

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.

Abstract: Embodiments described herein provide a system for facilitating efficient indexing in a database. The system can maintain a data table in the database. The data table includes a first column for structured data and a second column for unstructured text. A row of the data table can include a first piece of data in the first column and a second piece of data in the second column. During operation, the system performs word segmentation on the second piece of data to generate a first set of semantically meaningful word segments. The system then generates a set of index entries that corresponds to the row. A respective index entry includes an index generated from the first piece of data and a corresponding word segment of the first set of semantically meaningful word segments.

Abstract: A steering wheel of a vehicle includes a steering wheel armature made of metal, a steering wheel rear cover made of plastic, and an airbag module. The steering wheel rear cover is located on a bottom of the steering wheel armature and the airbag module is mounted above the steering wheel armature. An ? spring assembles the airbag module onto the armature. At least a supporting rib extends from the steering wheel rear cover and is located between the ? spring and the steering wheel armature for supporting the ? spring. The supporting rib erases a gap between the ? spring and the steering wheel armature and it is formed by plastic, thereby reducing noise efficiently.
