Abstract: A carrier recovery device and a carrier recovery method are provided. The device includes a phase detection module, a computation module, a phase angle adjustment module, a loop filter, and a conversion module. The phase detection module receives an IF signal, and detects a sine and a cosine signals corresponding to the IF signal. The computation module receives the sine and the cosine signals, and computes a phase angle between the sine and the cosine signals. The phase angle adjustment module adjusts the phase angle according to one of the sine and the cosine signals and a threshold. The loop filter generates a frequency offset angle according to the phase angle. The conversion module generates a sine and a cosine parameters according to the frequency offset angle, and transfers the sine and the cosine parameters to the phase detection module.

Abstract: The present invention suggests a simplified and robust scanning method as a scenario for scanning video sources of a display device such as a TV or projector. The inventive method is attained by way of grouping the video sources and prioritizing the scanning priority for each video source group in terms of the viewing time statistic or the frame number statistic of each video source group. Therefore, the display device is capable of scanning each video source group based on the scanning priority to discover if there is a video signal inputted into the video source.

Abstract: A charging method for charging a battery module. The battery module receives a different charge voltage according to the voltage or current status of the battery module. The charge voltage is decreased to increase battery power when any battery voltage level is greater than a preset voltage. A charging system thereof is also disclosed.

Abstract: A cross-level digital signal transmission device between two systems for cross-level digital signal transmission. Bi-directional symmetrical transmission is achieved without using additional control signals, and use of the transmission signal itself eliminates the positive feedback loop. Thus, neither additional control signals nor resulting unsymmetrical circuits need be provided.

Abstract: An ultrasonic fog generator creates a fog of a liquid such as water. When the amount of liquid in the ultrasonic fog generator falls below a predetermined value, the liquid may be automatically refilled by a liquid source. A liquid recycling system may be provided to limit the amount of liquid in a fog that may otherwise undesirably condense in the ambient environment. The ultrasonic fog generator may be configured to release a fog periodically. Moreover, the periodically released fog may contain one or more fragrances. Further, a fog produced using water may contain negative ions that may be useful in treating a medical condition of a patient.

Abstract: An ultrasonic fog generator creates a fog of a liquid such as water. The visual appearance of the fog may be altered such as by being illuminated by one or more lights having one or more colors. Further, the fog may be used to deliver pharmaceuticals to one or both of the lungs of a patient.

Abstract: A grid terrain data collision detecting method for forward looking terrain avoidance comprising the following steps: the use of kinematics equation to analytically find out sampling points positions; processing the sampling points in sequence with time increments; and using function minimum value theory to detect collision with results obtained from the sampling point process step.

Abstract: A method for passivating a target layer. There is first provided a substrate. There is then formed over the substrate a target layer, where the target layer is susceptible to corrosion incident to contact with a corrosive material employed for further processing of the substrate. There is then treated, while employing a first plasma method employing a first plasma gas composition comprising an oxidizing gas, the target layer to form an oxidized target layer having an inhibited susceptibility to corrosion incident to contact with the corrosive material employed for further processing of the substrate. Finally, there is then processed further, while employing the corrosive material, the substrate. The method is useful when forming bond pads within microelectronic fabrications.

Abstract: A process for reworking a non-reflowed, defective microlens element shape, of an image sensor device, without damage to an underlying spacer layer, or to underlying color filter elements, has been developed. The non-reflowed, microlens element shape, if defective and needing rework, is first subjected to a high energy exposure, converting the non-reflowed, microlens element shape to a acid type, microlens shape, then removed using a base type developer solution. Prior to formation of a reworked microlens element shape a baking cycle is employed to freeze, or render inactive, any organic residue still remaining on the surface of the spacer layer, after the base type developer removal procedure. Formation of the reworked, microlens element shape, followed by an anneal cycle, results in the desired rounded, microlens element, on the underlying spacer layer.

Abstract: The present invention teaches how greater solder ball height can be achieved without the need to sacrifice areal density. The mold in which the solder is formed, is created in two steps. In a first exposure, a negative photoresist (preferably DFR) is patterned to form a conventional cylindrical mold. However, exposure and development time are adjusted in such a way that a layer of unexposed and undeveloped resist of reduced thickness remains covering the floor of the mold. This residual resist layer is given a second exposure and, after development, forms an annular insert in the bottom of the first mold. After the mold has been filled with solder (either through electroplating or by using solder paste) it is removed, the result being a solder bump made up of two contiguous coaxial cylinders the upper one having the larger diameter. After remelt, bumps having this shape form oblate spheroids rather than spheres.

Abstract: A method and an apparatus for preparing a backside-ground wafer for testing are described. The method includes the steps of first providing a calibration wafer that has a pattern formed on a top surface of an insulating material such as oxide or nitride. Three droplets of water are applied with each droplet sufficiently apart from the other droplets on the top surface of the calibration wafer. A backside-ground wafer that has a ground backside and a front side to be tested is then mated to the calibration wafer by mating the ground backside to the top surface of the calibration wafer with water droplets therein-between forming a bond by capillary reaction in-between the oxide pattern on the calibration wafer. The apparatus for mounting a backside-ground wafer to a calibration wafer consists of a slanted block having a top surface with a slant angle between about 10° and about 30°.

Abstract: The container has an enclosure member and a body member which together enclose a volume to accept wafers for storage, for handling, or for transportation. The body member has a base, and a plurality of spaced upright arcuate members supported on the base that are adapted to encircle wafers stacked on the base. An enclosure member has a circular top wall and a cylindrically shaped wall that is adapted to encompass and enclose the arcuate members. The retainer element has a flat central portion, and a plurality of flexible outwardly extending flaps depending from the central portion. The retainer element fits within the arcuate members of the body member with the end portions of the flaps positioned in the slots between the arcuate members.
