Abstract:
A packing box includes a first triangular lateral board part, an upper board part, a bottom board part, a covering board part, and a second triangular lateral board part, which includes upper and lower parts; when the packing box is in a spread-out position, it has a first sticking plate lying between the first triangular lateral board part and the bottom board part; the first sticking plate joins the first triangular lateral board part and the bottom board part together, and therefore can prevent the covering board part from being folded along a middle portion when one is folding and erecting the packing box; therefore, folds won't be formed on the covering board part to spoil the appearance.
Abstract:
A method for tuning a plurality of write strategy parameters of an optical storage device includes detecting a plurality of patterns. Each pattern corresponds to a pit or a land on a phase-changed type optical storage medium accessed by the optical storage device. The method further includes performing calculations corresponding to a plurality of data types and generating a plurality of data-to-clock edge deviations respectively corresponding to the data types. Each pattern belongs to a data type. The data-to-clock edge deviations are utilized for tuning the write strategy parameters corresponding to the data types respectively.

Abstract:
A lamp apparatus include a lamp body, at least an alternating current light-emitting diode and a plug. The alternating current light-emitting diode is disposed on a lamp body. The plug is electrically connected to the alternating current light-emitting diode. In lamp apparatuses utilizing AC LED, heat generated thereby is almost concentrated on chips. Compared with conventional lamp apparatuses utilizing DC LEDs, heat generated thereby is distributed on chips and outer rectifier. In lamp apparatuses utilizing AC LEDs, heat generated thereby is almost concentrated on chips because AC LEDs operate directly with AC electric power, omitting a rectifier and preventing power loss during operation of power rectification. Therefore, the heat accumulated on the chips of the AC LEDs is enough to be used to evaporate essential oil. In another embodiment, the invention utilizes low-resistance pure water surrounding the AC LED to dissipate its heat.
Abstract:
A sleeve with an indication assembly comprises a sleeve; and a toggle having an inner diameter corresponding to an outer diameter of the sleeve; and the toggle being made of aluminum alloy; a surfaces of the toggle being anodic processed so as to form with a protection film of different colors; thus the surfaces of the toggle is prevented from cracking, collision, mist and falling off. Furthermore, in another case, the toggle has an inner diameter corresponding to an outer diameter of the sleeve; and the toggle is made of iron. A surface of the toggle is electroplated so as to form with a copper layer and then is performed with anodic processing so as to have the effect of indication of sizes.
Abstract:
The invention provides an optical disk drive. The optical disk drive comprises a pickup head, a seek control device, a lens vision characteristic decoder, and an anti lens shift device. The pickup head comprises a sled and a lens for projecting a beam on a disk. The seek control device moves the sled, and shifts the lens with a shift distance relative to an origin at a center of the sled. The equalizer derives a servo signal from a reflection of the beam. The lens vision characteristic decoder obtains a vision characteristic of the lens according to the servo signal and determines a track-on direction according to the vision characteristic. The anti lens shift device triggers the seek control device to perform a track-on process according to the track-on direction.

Abstract:
Calibration methods are provided for determining servo parameters to enhance an optical drive in reading and writing a blank optical disc. First, test data is written on the blank disc with various writing parameters. Second, the written test data is read from the optical disc with various reading parameters. A plurality of quality measures are obtained, each corresponds to a specific combination of the writing parameter and the reading parameter. An optimal writing parameter and an optimal reading parameter are determined by comparing the quality measures with respect to both the reading and writing parameters respectively.
Abstract:
A method for updating a tap coefficient of a decision feedback equalizer is provided. The method includes sampling a first input signal received by a sampler of a decision feedback equalizer. It is determined if an amplitude of the first input signal falls within a range defined between a first predetermined voltage level and a second predetermined voltage level. If the amplitude of the first input signal falls outside the range, a tap coefficient is updated to generate an updated tap coefficient that is fed back to adjust an amplitude of a second input signal received at an input end of the decision feedback equalizer. If the amplitude of the first input signal falls within the range, the tap coefficient is free from being updated.
