    Abstract: The present invention relates to an apparatus and method for analyzing the read-out signal of an optical storage media and is especially suitable for the HF signal read from the digital video disk (DVD), wherein the HF signal comprises many different signals whose periods are integer times of the system period. The present apparatus can be used to record the maximum or minimum values of specific period of signals for further statistical analyses. Furthermore, the AC and DC components of the HF signal can be processed independently and the results will be combined together for further processes. Therefore, it only takes moderate memory capacity and acquisition time to obtain accurate maximum or minimum values of the specific period of signals.

    Abstract: The specification discloses a braking method for a single-phase motor, which is applied to a single-phase DC brushless motor driven by a three-phase motor driving IC. The invention uses a control unit to compute the rotational speed of the single-phase motor according to a rotation number signal generated by the motor rotational axis. When the rotational speed is below a threshold, the motor driving IC is controlled to stop rotating the single-phase motor. Through the single-phase motor braking method disclosed herein, the problem of unable to determine the rotational direction of a single-phase motor within a three-phase motor driving IC existing in the prior art can be solved by merely modifying the program in the control unit without adding system elements. Since currently the single-phase DC brushless motor and the three-phase motor driving IC have competitive superiority in prices, if the three-phase motor driving IC can directly drive the single-phase DC brushless motor without requiring additional system elements the whole system cost can be lower. On the other hand, this method can avoid the delay problem due to fewer single-phase motor driving IC manufacturers on the market.

    Abstract: An air-operated toy gun including a gun body, a triggering device, an air pump device, and a projectile. The air pump device is arranged inside the gun body and has an air cylinder. A blow tube that is connected to the air cylinder has an end extending out of the gun body. A piston is driven by the triggering device within the air cylinder to produce compressed air. The tubular projectile, made of a medium hard foam material and closed at one end, is mounted on the front end of the blow tube. When compressed air, produced by the movement of the piston in the air cylinder by movement of the triggering device, exhausts from the blow tube; the projectile is ejected forward, resulting in an amusement effect.

    Abstract: A method and a system of generating a non-deterministic model of an artifact system for a received goal are provided.A description of artifacts and services associated with an original version of a process is received. Component automata represent the artifacts and services that are automatically generated. There is one component automaton for each attribute of an artifact. States of a particular component automaton represents potential values of a particular attribute and transitions between the states represent services that operate on the values. A non-deterministic model of the process is generated by automatically generating a composite automaton, which includes the component automata, based on the received goal. The composite automaton provides the non-deterministic model of the process.

    Abstract: This invention relates to an apparatus and a method for multistage hierarchical pyrolysis and gasification of solid fuels. The apparatus comprises a feeding device 1, a multistage fluidized bed reactor 6, a residual discharging valve 9, a cyclone 10 and a condenser 11. A gas inlet is provided at the bottom of the multistage fluidized bed reactor 6 and a number of stages of fluidized beds 3 are provided within the multistage fluidized bed 6, wherein the fluidized beds 3 are separated by a number of perforated distributors 5. The top stage fluidized bed 3 is connected with the feeding device 1 and the coal fed thereto is heated by char obtained from pyrolysis in this stage and the mixture of high temperature ascending pyrolysis and gasification gas to undergo pyrolysis reactions at low temperature, thereby to obtain solid particles after preliminary pyrolytic process. The solid particles flow downwards through an overflow standpipe 4/the perforated distributor 5 to the next stage of the fluidized bed and then are pyrolyzed through being heated by char and the mixture of pyrolysis and gasification gas. The solid particles in turn pass into the next stage of the fluidized bed and finally enter into the bottom stage fluidized bed to undergo gasification reactions. More light fractions in tar can be produced using the present apparatus and method.

    Abstract: A power converter including a resonant circuit is controlled by pulse width modulation (PWM) of a switching circuit to control current in the resonant circuit near the frequency of the resonant circuit (a null-immittance criterion) in order to control current and voltage at the output of the resonant circuit. Further control of voltage can be performed by PWM of a switching circuit at the output of the resonant circuit such that centers of the duty cycles of respective switches for the output of the resonant circuit are substantially synchronized and substantially symmetrical about centers of said duty cycles of respective switches at the input of the resonant circuit. Thus, operation of the converter is substantially simplified by using only PWM, a wide range of input and output voltages can be achieved and the converter circuit can be configured for bi-directional power transfer.
