Abstract:
An automatic marking method for Karaoke vocal accompaniment is provided. In the method, pitch, beat position and volume of a singer are compared with the original pitch, beat position and volume of the theme of a song to generate a score of pitch, a score of beat and a score of emotion respectively, so as to obtain a weighted total score in a weighted marking method. By using the method, the pitch, beat position and volume error of each section of the song sung by the singer can be exactly worked out, and a pitch curve and a volume curve can be displayed, so that the singer can learn which part is sung incorrectly and which part needs to be enhanced. The present invention also has the advantages of dual effects of teaching and entertainment, high practicability and technical advancement.
Abstract:
A Lactobacillus plantarum BB9 capable of adhering to gastrointestinal tract and cholesterol removal is isolated from fruits and exhibits high BSH activity. In-vitro tests demonstrate that Lactobacillus plantarum BB9 has good acid and bile tolerance, and strong ability to adhere to intestinal cells. In-vivo tests show that hamsters fed high cholesterol diets added with BB9 strain have cholesterol and triglycerides in blood and liver effectively reduced, and their HDL-c/LDL-c ratios in blood are significantly higher than those of hamsters fed Lactobacillus acidophilus ATCC 43121 strain. It is hoped that the excellent acid and bile tolerance and intestinal adherence of the lactobacillus strain provided herein could produce cholesterol-lowering effect in humans.
Abstract:
A method for keying human voice audio frequency includes the steps of setting the human factor of the singer; recording the singing of the singer; calculating the audio frequency by an audio frequency counter; recording the maximum ground frequency by the recorder; estimating a maximum fundamental audio frequency thereof by the diapason estimator; and converting the maximum fundamental audio frequency into musical terminology, the best audio frequency of the singer being determined. The method for keying human voice audio frequency is very easy and fast.
Abstract:
A composition of a water-repellent agent has a solvent and a solute. The solvent is water. The solute is dissolved in water and has isocyanate-acryl, non-ionic fluoro-acryl, 4,4-dipheylmethane diisocyanate, zinc acetate and polyethylene wax. Isocyanate-acryl has a concentration in a range of 10˜40 gram in per liter of the water-repellent agent (i.e. 10˜40%). Non-ionic fluoroacryl has a concentration in a range of 80˜150% t. 4,4-dipheylmethane diisocyanate has a concentration in a range of 5˜12%. Zinc acetate has a concentration in a range of 1˜20%. Polyethylene wax emulsion has a concentration in a range of 1˜40%. Therefore, a fabric treated with the present invention has good waterproof ability, widely enhanced color fastness in light and improved tear-resistance strength at the same time.
Abstract:
A lighting module comprises a bezel, a lamp and a fixing component. The lamp includes two straight portions and one bending portion therebetween. The two straight portions substantially being parallel to each other. A fixing component includes a main body fixed with the bezel and two C-ring structures individually having two ends connecting with the main body. The two straight portions are individually encircled by one of said two C-ring structures and in touch with the main body.
Abstract:
A liquid crystal display and backlight module thereof. The backlight module includes a light source and a light source holder, supporting and abutting the light source. The light source holder comprises an airflow passageway and a plurality of vent holes. Each vent hole communicates with the airflow passageway such that heat produced by the light source is dissipated through the vent holes and the airflow passageway to the exterior of the backlight module.
Abstract:
A display device and a light source block used therein are provided. The display device includes the light source block, a film set, and a display panel. The light source block has a reflective surface, a film supporter intersecting the reflective surface at an edge, and a panel supporting surface. The film supporter connects an end of an extremity surface, and the panel supporting surface connects the other end of the extremity surface. The film set is disposed on the film supporter, and the display panel is disposed on the panel supporting surface. The display panel has a display area and a light-shielding unit disposed outside the display area. The edge between the reflective surface and the film supporter falls into a vertical projection of the light-shielding unit.
Abstract:
A method for manufacturing PCB, a display module and a method for fabricating a display module is disclosed. The method for fabricating a display module comprises the following steps. A printed circuit board with at least one locating pin formed thereon is provided. The printed circuit board is positioned on a backboard of a display module by means of the locating pin.
Abstract:
An etching-free ceramic substrate preparation process includes the step of bonding a dry film to one side of a ceramic plate, the step of applying an exposing and developing process to the dry film to form a predetermined circuit layout on the dry film, the step of coating a thin-thickness first metal layer on the ceramic plate and the dry film, the step of forming a copper layer on the first metal layer by a coating technique, the step of cutting/grinding the dry film, the first metal layer and the copper layer to remove the dry film from the ceramic plate, the step of obtaining the desired height of the copper layer on the ceramic plate, and the step of forming a second metal layer on the surface of the copper layer by a coating technique.
