Methods and systems for transmission of multiple modulated signals over wireless networks
A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The inventive method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations.

Then, it is determined whether the set exposure parameters are within a predetermined range and when they are out of the range and if a high-brightness imaging region is present in the image due to high-brightness incident light, it is again determined whether it is necessary to remove the high-brightness imaging region. When it is determined to be necessary, the high-brightness imaging region is extracted and is removed from the image, thereby enabling the camera to image the object with suitable brightness even when a bright light source such as the sun is within the camera angle of view. |

Thermal printer
When printing is performed by dividing a thermal printer head into segmented blocks, the number of dots to be printed in one line is changed, depending on the case, high-speed printing with a small division number of the segmented blocks, or low-speed printing with a large division number of the segmented blocks. When the division number of the segmented blocks is large and printing is performed at a low speed, paper feeding within one line is performed by multiple pitches to prevent the paper sheet from halting in one line, and energization is performed for each pitch to prevent occurrence of gaps between dots and between lines, by increasing the number of dots to be printed in one line. In the multiple pitches in one line, the ratio of energization amount to be fed in each pitch is changed to reduce a difference in density among pitches in one line. Accordingly, when printing is performed by using segmented blocks of the thermal printer head, even though the division number of the segmented blocks is large and printing is performed at a low speed, printing without generating a gap between dots is possible. |

A periodic baseline adjustment algorithm is disclosed that can increment or decrement individual baseline sensor output values by one count to provide periodic fine-tuning of the baseline to track temperature drift.

Manufacturing method of semiconductor integrated circuit device
When relatively hard Au bump electrodes are mass-produced by electrolytic plating while ensuring usually required properties such as a non-glossy property and shape-flatness, combination of conditions, such as low liquid temperature, high current density, and low concentration of added Tl (thallium) that is an adjuvant, will be selected by itself. However, in such conditions, there is a problem that it is difficult to maintain the Tl concentration in a plating solution and, when the Tl concentration is reduced, defective appearance of the Au bump electrodes is generated by anomalous deposition. Conventionally, there has been no means to directly monitor minute Tl concentration and the Tl concentration has been controlled by analyzing the plating solution periodically. However, this can not prevent generation of a lot of defective products. One invention of the present application relates to detecting the added amount of Tl in the plating solution by monitoring the voltage applied to the plating solution in formation of bump electrodes by an electrolytic Au plating using a non-cyan based plating solution according to the manufacturing method of a semiconductor integrated circuit device. |

A sandwich panel in which a middle material 2 and a surface material 3 that are each formed by laminating a plurality of fiber bodies are laminated from inside to outside on the upper and lower surfaces of a hollow columnar core 1, wherein the middle material 2 is composed of a set of unidirectional fiber bodies 4, 5 whose fibers are aligned in one direction, fibers in a first unidirectional fiber body 4 are in a direction that is substantially parallel to an edge of the sandwich panel, fibers in a second unidirectional fiber body 5 are in a direction that is substantially orthogonal to an edge of the sandwich panel, and bonding layers 6, 7 having a resin content ratio of 50% or higher are provided between the unidirectional fiber bodies 4, 5 and between the hollow columnar core 1 and an inside unidirectional fiber body 5. |

Printed magnetic ink overt security image
A security image and method of forming said image is disclosed wherein a substrate having an image or indicia thereon is coated with a dilute solution of pigment flakes in an ink or paint. The flakes are subsequently aligned in a magnetic field and are fixed after the field is applied. Most or all of the flakes in a region are aligned so as to be partially upstanding wherein their faces are essentially parallel. Coating the image with flakes yields a latent image which can be clearly seen at a small range of predetermined angles. |

Sensor-securing apparatus and camera module
According to one embodiment, a sensor-securing apparatus has a frame having a sensor-mount region to hold an image sensor that generates heat while operating. The frame has a first adhesive-applying hole and a plurality of second adhesive-applying holes. The first adhesive-applying hole opens in the sensor-mount region and faces the center part of the image sensor. The second adhesive-applying holes are smaller than the first adhesive-applying hole, open in the sensor-mount region and are arranged around the first adhesive-applying hole. Adhesive is filled in the first adhesive-applying hole and the second adhesive-applying holes. The adhesive secures the image sensor to the frame. |

Optical information recording medium
An optical information recording medium has a substrate, and an optical reflection layer, an optical recording layer containing an organic dye, an interlayer, and a cover layer formed in this order on the substrate. The interlayer contains a sputtered Nb2O5—Al2O3-based composite oxide having an Nb2O5 content of more than 50 mol % and less than 60 mol %. |
