38results about How to "Improve transfer function" patented technology

Disclosed are a server system for performing moving picture data communication with a client device over a wireless network, and an operating method thereof. A server device compresses the moving picture data received from an external medium at a variably controlled compression rate according to transmission bandwidth of the current wireless network and an image quality level set by a user in response to a request of the client device. Moreover, the server device transmits the compressed moving picture data to the client device in a wireless fashion. Therefore, transmission delay and playback delay can be avoided and data loss is avoided during a data transmission operation, such that stable data communication can be performed.

A novel CMOS image unit pixel layout having a photodiode including an optically optimized square image sensing region. The square image sensing layout provides for reduced electrical and color crosstalk and improved modulation transfer function (MTF) between neighboring pixels of an array of pixels.

The invention discloses an electric drum device, which comprises a drum body, a track and gears. The gears are radially arranged on the outer periphery of the drum body, outer peripheries of the gearsare provided with a plurality of gear teeth in uniform distribution, the inner surface of the track is provided with a plurality of track grooves matched with the gears, and the track grooves are inarray distribution. The drum body drives the gears to rotate, and the gear teeth on the gears are matched with the track grooves of the track to drive the track to rotate. The electric drum device hasadvantages that the drum body drives the gears to rotate, and the gear teeth on the gears are matched with the track grooves of the track to drive the track to rotate, so that a transmission functionof the track is greatly improved, and simple structure and convenience in later maintenance are realized.
