Abstract: This invention relates to Bluetooth earphone. Existing Bluetooth earphones have some problems: users must wear the earphone to use it, so that the user will feel uncomfortable if the user uses the earphone for a long time. In order to solve these problems, this invention has added a speaker with larger power (i.e. 3W) and configured corresponding speaking amplifying circuit and switching circuit based on the existing Bluetooth earphones. With these new features, the user can adjust his/her Bluetooth earphone by switching different circuit so that it can work in earphone mode or speaker mode. When the Bluetooth earphone works in speaker mode, the user can hear normal voice without wearing the Bluetooth earphone. Obviously, this new invention can be used not only as a common earphone, but also as a speaker. In addition, a call identification circuit, a Bluetooth transmitting circuit and a microphone can be added to expand functions of the whole Bluetooth earphone.

Abstract: This invention publicizes a kind of fingerprint locks with patterns of propagation, comprising of lock body, characterized by a raised fingerprint groove for lock opening, a slide lid provided on the lock body with slide connection to the body, and surrounding the fingerprint groove. There is an animal and plant pattern on surface of the slide lid and another appropriate animal and plant pattern below the lock body, which is of pattern consistent with that on the slide lid and both together forms a 3D propagation pattern. Because of the above-mentioned structure, the lock is of a beautiful appearance and strong effect of decoration.

Abstract: A system and method to analyze interactions among software artifacts within enterprise applications. The system includes an artifact analyzer module an artifact code parsing module and an artifact token processing module. The artifact analyzer module generates artifact tokens associated with trigger points in which processing control passes between a first software object and a second software object in the enterprise application and an interaction token repository for storing artifact tokens. The artifact tokens describe identity of the first software object, ownership of the first software object containing the trigger point, a location within first software object of the trigger point, and identity of the second software object. These artifact tokens are stored within an interaction token repository for later use.

Abstract: A high precision hydraulic synchronous and proportional flow dividing and flow collecting apparatus comprises two hydraulic motors having the same displacement and their crankshafts be connected into one crankshaft. The two hydraulic motors have a common oil inlet port, and have an individual oil exhaust port respectively. In the casing of the two hydraulic motors a plunger cylinder and a plunger piston that is matched with the plunger cylinder are provided. Between the plunger cylinder and the plunger piston an automatic compensating combined sealing unit is provided. Between the plunger piston and the linking rod lubrication damping holes are eliminated. Thereby, the leakage amount is further reduced. The advantage of the present invention are that it has the synchronous control function; the synchronous precision comes up to ±02%; it is of simple structure, high efficiency, energy saving, low cost, smooth operation noise, reliable performance and convenience in maintenance.

Abstract: A method for automatic re-population of data in a database in response to detection of at least one script-transaction, the database includes a plurality of tables. The script-transaction is carried out in response to a script input. The method includes truncating at least one table, which is being modified by at least one of a persistent trigger and a non-persistent trigger. The persistent trigger updates a table and the non-persistent trigger performs one of an insert operation and a delete operation on a table. Further, the method includes executing a non-persistent trigger corresponding to each truncated table of the database in a predefined-update-sequence. Also, the method includes executing at least one persistent trigger corresponding to each truncated table of the database.

Abstract: The proposed technique provides simultaneous read and writes from a display controller using low-cost SDRAMs. This is achieved, in one example embodiment, by receiving a sequence of video frames at a first variable frame rate. A first video frame is then written in a first single-ported memory. The first video frame is then read from the first single-ported memory upon completing the writing of the first video frame in the first single-ported memory. The reading of the first video frame is then repeated from the first single-ported memory to maintain a second frame rate. The second frame rate is higher than the first variable frame rate. A second video frame is then written in a second single-ported memory upon completing the writing of the first video frame in the first single-ported memory such that the writing of the first video frame and the second video frame is at the first variable frame rate.

Abstract: A large resisting distortion and modularized comb-type bridge expansion joint, comprises at least two modules located parallel in the direction of a bridge's width, and each module includes a fixed comb plate (2) and a movable comb plate (1), which are respectively disposed on girders located at the two sides of the bridge expansion joint, said movable comb plate (1) crosses over the bridge expansion joint, both of said fixed comb plate (2) and said movable comb plate (1) have a plurality of comb teeth (22), (11) at their opposite ends, and the comb teeth (11) of said movable comb plate (1) interdigitate with the comb teeth (22) of said fixed comb plate (2), characterized in that the root of said movable comb plate (1) rotatablely joints with a seat (5) fixed on the girders, and the comb teeth (22) of said fixed comb plate (2) rotatablely joints with the root of said fixed comb plate (2), while, the middle of the comb teeth (22) of said fixed comb plate (2) is movably set on an underlay (6) fixed on the girde

Abstract: This invention has disclosed a method for preparation of food-grade zeaxanthin through chemical isomerizaton reaction from lutein. The technical issues to be solved in this invention are quite low product yield obtained with existing methods, need of purification treatment process, and inadaptability to industrialized production. The technical schemes of this invention are: a. Mix xanthophyll crystal or its fatty acid ester with food-grade glycol or propylene glycol, for full dissolution under 60-90° C. temperature. Add organic alkali into the mixed liquor acquired from step 1, for isomerization reaction to take place under inertial environment. c. Dilute the reaction solution gained from step b with the mixed solution of deionized water and ethanol, and separate the obtained crystal with conventional separating method. d. Vacuum dries the acquired crystal from step c, to get the zeaxanthin crystal.

Abstract: A plug connection type eyeglasses assembly includes a pair of primary eyeglasses and a pair of secondary eyeglasses. A primary nosepiece of the primary eyeglasses is provided with a plughole, while the secondary eyeglasses is provided with a plug connector or a plug type turnover mechanism at a position corresponding to the primary nosepiece of the primary eyeglasses. The plug connector or the plug type turnover mechanism is inserted into and engaged with the plughole, thereby coupling the primary eyeglasses and the secondary eyeglasses.

Abstract: A method and apparatus for a frequency shift keying (FSK) demodulator use a configuration to improve the autocorrelation for better receiver performance. The demodulator uses parallel first and second lines connected to the same input signal, the first line having a delay element to provide an integer-delay of M, the second parallel line having a filter for causing a group delay of ?+M where ? is fractional, and a multiplier for receiving the signals from said first and second lines and generating a resultant signal from which a base band signal can be recovered. The resultant signal is passed through a low pass base band filter to recover the base band signal. ? may have a value of 3.25 and M may be 6. The demodulator may selectively be implemented in caller ID service and in low end modems chosen from a group comprising V.21, Bell 103, V.23 and Bell 202A modems.
