摘要： A vehicle seat head rest for mounting to a vehicle seat of a vehicle includes a head pillow and an electronic appliance including a screen module detachably mounted at the head pillow. The head pillow includes a pillow body having a receiving cavity formed at the rear side of the pillow body, a mounting arrangement for mounting to the vehicle seat, and a replaceable skin detachably encasing the pillow body at a position that a peripheral edge of the replaceable skin is folded at the rear side of the pillow body. The screen module is detachably mounted within the receiving cavity and is supported by an interior wall thereof. Thus, the peripheral edge of the replaceable skin is hidden after the screen module is detachably mounted at the rear side of the head pillow.

摘要： A dynamic image delivery system receives a client request for an image at an image caching server. The image caching server measures the client's network access speed and looks for an appropriate pre-rendered copy of the requested image that is rendered for the client's network access speed in local storage. If the appropriate rendered copy is found, then the image caching server sends the rendered image to the client. If it is not found, then the image caching server dynamically renders a copy of the image and sends it to the client.

摘要： A novel device for pole splitting which can be employed in multistage amplifiers having a final stage and a prior stage. The device comprises a first capacitor connected between the output of the prior stage and the output of the final stage, a source follower, and a second capacitor connected between the output of the prior stage and the source follower. The source follower provides an offset voltage that reduces variation of the total capacitance of the first and second capacitors. In a preferred version of the present invention, the first and second capacitor each comprise a MOSFET transistor having a certain threshold voltage. The offset voltage is set to be at least the threshold voltage of the MOSFET transistors. In a preferred version, the source follower comprises a plurality of MOSFET transistors, which includes a MOSFET transistor having a gate connected to the first capacitor and a source connected to the second capacitor.
