摘要： Modern fiber optic networks typically transfer data using encoding in which the clock is transmitted along with the data, for example in NRZ format. In order to use the clock to process the data, the clock signal must be extracted from the data signal. Because the data and clock may travel through different circuit paths they may have different propagation delays and a phase offset between the clock and data may result. Data and clock phase offsets are more problematical as data transmission speed increases. Furthermore the data/phase offset is typically not constant and may change with a variety of variables. To compensate for the changing offset, one or more variable delays are inserted in the phase detector circuitry. The timing of the variable delay is controlled by a bang-bang phase detector, such as an Alexander phase detector, which determines if the clock is leading, lagging, or in phase with the data. The delay control loops are low bandwidth, because the phase offset generally changes slowly, and because the loops should not respond to temporary upsets such as noise spikes. The delay control loops integrate the output of the bang-bang phase detector and use the output to control a decimated up down counter, which is then further used to control one or more variable delays. The counter can be pre-loaded with a default start point, and the bandwidth of the loops can be dynamically adjusted by changing the decimation ratio and sample periods of the loop.

摘要： A dispenser for storing and applying a supply of cosmetic powder, includes a container and closure cap. The closure cap carries an applicator brush that is manually advanceable or retractable with respect to the closure cap. The mouth of the container is covered by an apertured transverse wall and a lid thereon, the lid normally blocking communication between the powder in the container and the brush. When the closure cap is removed, the lid can be manually lifted by means of a hinged connection, to as to expose a small accumulation of powder that has adhered to the transverse wall. The applicator brush is then advanced, and used in the manner of a dabber to pick up particles of the powder and apply them to the user. Simplified components and assembly characterize the completed unit.

摘要： A method and a system for fabricating a liquid crystal film are proposed. First of all, mechanical rubbing is performed on a surface of a plastic substrate. The surface of the substrate is applied with dispersed liquid crystal material over the substrate. At least one cycle annealing treatment is performed to orientate liquid crystal molecules in a fixed direction, so that a liquid crystal solid film is formed by curing the liquid crystal molecules. In addition, a method for fabricating a brightening film using the liquid crystal solid film is also proposed. The method is applicable to a continuous process for forming a cholesteric liquid crystal film on the plastic substrate, and fabricating a reflective cholesteric liquid crystal brightening film using the cholesteric liquid crystal film, so that light transmittivity and intensity are effectively increased under the same backlight source.

摘要： A cosmetic container including interleaved substantially vertical walls upwardly and downwardly extending respectively from a base component and from a product reservoir, with a further downwardly extending tongue projection from an underside of its cover, and in which cooperating detents on the tongue projection and on the reservoir pivot the cover open and closed, to form an internal hinge which is unobservable to a consumer, thereby providing a more aesthetically pleasing appearance to the container in both its opened and closed positions.
