  • Publication number: 20120034385
    Abstract: A continuous process for manufacturing a porous material is provided. The process includes the steps of mixing a non-ionic surfactant with a precursor of a carbonaceous material to form a mixture comprising a continuous phase and a liquid crystalline mesophase comprising the non-ionic surfactant, wherein the precursor is essentially located in the continuous phase, coating or depositing the mixture onto a non-woven substrate, drying or heating the mixture, and converting the precursor to form a polymer.

  • Patent number: 8035361
    Abstract: A boost device boosts an input voltage to an output voltage across an output capacitor, and includes first and second output diodes coupled to the output capacitor, and a transformer coupled to first and second switches, first and second switching circuits, and to the first and second output diodes, and receiving the input voltage. The first and second switches are operated alternately in an ON-state, and have overlapping duty cycles. The first and second switching circuits are operable to suppress conduction losses for the first and second switches. The transformer has a bi-directional magnetic circuit. Electric energy is transformed through induced currents of the transformer, and a small amount of energy attributed to an exciting current of the transformer is used for voltage boosting, thereby attaining a relatively high output power.

  • Patent number: 8009444
    Abstract: A boost device boosts an input voltage to an output voltage across an output capacitor, and includes an output diode coupled to the output capacitor, and a transformer coupled to a first switch, a clamp circuit and a boost circuit. The clamp circuit is coupled across a first winding of the transformer, and includes a clamp capacitor coupled in series to a second switch. The output capacitor is capable of being charged through the output diode with an induced voltage across a second winding of the transformer. The boost circuit is capable of being charged with the induced voltage across the second winding, and of charging the output capacitor so as to boost the output voltage across the output capacitor.

  • Publication number: 20110078684
    Abstract: A method and system for facilitating runtime memory analysis. The method includes: assigning a unique ID for each task in a running program; recording memory access events occurring during the running program, including the IDs of the task performing the memory accesses; issuing a task termination notification in response to a task terminating, the task termination notification including the ID of the terminating task; and releasing all the memory access events having the ID of the terminating task in the memory, in response to the task termination notification. This method and system can ensure that the memory access events stored in the memory will not increase unlimitedly, so that the memory overhead is reduced remarkably and dynamic memory analysis can be faster and more efficient.

  • Publication number: 20100333110
    Abstract: A deadlock detection method and computer system for parallel programs. A determination is made that a lock of the parallel programs is no longer used in a running procedure of the parallel programs. A node corresponding to the lock that is no longer used, and edges relating to the lock that is no longer used, are deleted from a lock graph corresponding to the running procedure of the parallel programs in order to acquire an updated lock graph. The lock graph is constructed according to a lock operation of the parallel programs. Deadlock detection is then performed on the updated lock graph.
