    摘要： A system and method for resizing tiles on a computer display is provided. The tiles are automatically sized until a user takes control after which the user may manually size the tiles. Size limits may be set for the tiles. If an attempt is made to automatically resize a tile above a specified limit, then a notification may be sent to the user requesting approval for the new tile size. If the user does not approve the new size, then the tile will be placed in a manual sizing mode in which further automatic resizing is limited. If the user approves the new size, then further automatic resizing may occur without requesting further approval. The tiles are prevented from being automatically resized too frequently, which could be distracting or annoying to a user.

    摘要： A method and device for mounting and centering a thin wall hub of a driven member onto a drive shaft provides the shaft with a radial end face which projects an axially extending reduced diameter threaded stud which fits within a central aperture of the hub and secures a nut to clamp the hub between the end face and nut. A raised shaft embracing portion centered on the hub axis snugly embraces the outer periphery of the drive shaft and axially aligns the two members. The drive shaft may also incorporate a drive pin which extends axially from the end face and is seated in a second aperture in the hub to provide effective driving of the hub by the drive shaft.

    摘要： A BPSK Costas-type PLL circuit in which the circuit is positively prevented from falsely locking on to the input signal and in which the need for a complex lock detector is eliminated. The output levels of both the 0.degree. and 90.degree. sub-loops of the circuit are detected and a difference formed between the detected outputs. When the difference exceeds a predetermined reference level, it is determined that true locking has occurred, whereupon a sweep generator, used in achieving initial lock, is decoupled from the PLL circuit.
