The present invention provides a multilevel read-only optical disk and the method for producing the same. The multilevel read-only optical disk comprises a plurality of the recording pits, each of the longitudinal sections of the recording pits has a multilevel arbitrary shape; the areas of the longitudinal sections of the recording pits are not identical each other; the area of each of the longitudinal sections of the recording pits is defined by the following formula: S=∫h(x)dx, where S represents the area of each of the longitudinal sections of the recording pits, x represents the coordinate value along the width direction of the recording pits, h(x) represents the pit-depth distribution function of the longitudinal sections of the recording pits and the region of the integration covers the whole longitudinal sections of the recording pits. Furthermore, the run length of the multilevel read-only optical disk is limited. The present invention obtains the advantage of both multilevel storage technology and run length limited (RLL) codes. They can improve prominently the storage capacity and data transfer rate of read-only optical disk without changing the wavelength of the laser and optical numerical aperture, and are most compatible with the conventional read-only optical disk system.

A virtual ground nitride read-only memory array has a matrix of nitride read-only memory cells in which during an erase operation the non-erasing side of nitride read-only memory cells are connected to a common node for enhancing the erase uniformity of the nitride read-only memory array. If an operation requests erasing on the left side of nitride read-only memory cells, a positive voltage is supplied from an internal power supply to the left side for each of the nitride read-only memory cells, and the right side for each of the nitride read-only memory cells is discharged to a common node. The voltage level of the common mode is selected to be sufficiently high in order to prevent from punch through while at the same time sufficiently low to maintain the lateral electric field for erase operation to function optimally.

A new design is provided for the heat spreader of a semiconductor package. Grooves are provided in a surface of the heat spreader, subdividing the heat spreader for purposes of stress distribution into four or more sections. This division of the heat spreader results in a reduction of the mechanical and thermal stress that is introduced by the heat spreader into the device package. Mechanical and heat stress, using conventional heat spreader designs, has a negative, stress induced, effect on the semiconductor die, on the contact points (bump joints) of the semiconductor die and on the solder ball connections of the package.

Disclosed is a method and system for automatically testing a raster image processor. The method may identify the correctness of the bitmap output by the raster image processor to be tested by comparing an abstract code of a bitmap generated by the RIP to be tested with that generated by a reference RIP to determine whether they are consistent with each other, so as to identify the correctness and stability of the RIP to be tested. Furthermore, the test samples can be submitted automatically. Thus, the convenience and efficiency are improved with respect to the manual submitting.

The invention discloses a method and a system for generating a boundary in the process of rasterizing a vector graphic as well as a method for producing the system and a method for clipping the vector graphic. The method for generating a boundary includes: segment-polylining the vector graphic and obtaining data of the line segments; obtaining data of the end pixels according to the data of the line segments; obtaining data of boundary pixels according to the data of the end pixels and the relationship between the data of the end pixels; obtaining bitmap data of the boundary pixels according to the data of the boundary pixels. The algorithm used in the invention is very simple and efficient; at the same time, the generation of the bitmap data of the boundary pixels can be carried out synchronously with the generation of bitmap data of the graphic itself. The invention can be used to be combined with a variety of scan line filling algorithms and the bitmap information of the boundary pixels can be obtained synchronously and efficiently in the process of rasterizing a vector graphic so that the quality of the output bitmap can be improved and controlled accurately.

An elongated catheter device with a distal balloon assembly is adapted for endovascular insertion. Coolant injected through the device may, in different embodiments, directly cool tissue contacting the balloon, or may cool a separate internal chamber. In the first case, the coolant also inflates the balloon, and spent coolant is returned to the handle via a return passage extending through the body of the catheter. Plural balloons may be provided, wherein a secondary outer balloon surrounds a primary inner balloon, the primary balloon being filled with coolant and acting as the cooling chamber, the secondary balloon being coupled to a vacuum return lumen to serve as a robust leak containment device and thermal insulator around the cooling chamber. Various configurations, such as surface modification of the balloon interface, or placement of particles, coatings, or expandable meshes or coils in the balloon interface, may be employed to achieve this function.

A method for transceiving non-USB peripheral device by an adapter and the adapter providing adaptation to an USB interface for the non-USB peripheral device, is disclosed. The adapter can read a capability report from the peripheral device and then converts the capability report to an USB-related report for facilitating accessing of the peripheral device. The adapter utilizes control commands and parameter set pre-defined by the adapter and the peripheral device to successfully access the peripheral device. The peripheral device has vendor identification (VID) and product identification (PID) and the controller transceives or detects the peripheral device with reference to the information of VID and PID.

This invention provides electromagnetic chips and electromagnetic biochips having arrays of individually addressable micro-electromagnetic units, as well as methods of utilizing these chips for directed manipulation of micro-particles and micro-structures such as biomolecules and chemical reagents. An electromagnetic biochip comprises an individually addressable micro-electromagnetic unit chip with ligand molecules immobilized on its surface. By controlling the electromagnetic field at each unit of the array and combining this control with magnetic modification of biomolecules, these chips can be used for directed manipulation, synthesis and release of biomolecules in order to increase sensitivity of biochemical or chemical analysis and reduce assay time. Other advantages with these chips include minimized damages to biological molecules and increased reproducibility of assay results.
