The ultrasonic front-end analog circuit is implemented with a modular design, the digital processing circuit and the power module being located at one half-region of the base board, and the ultrasonic front-end analog circuit being located at the other half-region of the base board. The ultrasonic front-end analog circuit is provided far away from the power module and the digital processing circuit such that interference from the power supply and digital circuits is prevented. | 06-04-2009 |
20090268403 | SHIELDED AND INSULATED HEAT REMOVING SYSTEM - Various embodiments disclose a shielded or isolated heat dissipating system comprising a case, a heat sink base, and a circuit board comprising at least one electronic device for which heat dissipation is desired. The heat sink base is attached to the case and together with the shielding case defines an enclosed space within which electromagnetic interference is reduced. Both heat-dissipation function and electromagnetic shielding function may be achieved by the combination of the heatsink base and the case while maintain electrical isolation with one or more specially treated components. The space required for mounting the system may also be reduced without adversely affecting normal and stable operation of the electronic device. | 10-29-2009 |

20160065657 | MESSAGE AND SUBSCRIPTION INFORMATION PROCESSING - A method and system for processing a message and subscription information is provided. Subscription information is obtained and parsed into a first set of predicates, whereby these predicates are not repetitive. One or more tree structures for the predicates and the subscription information are constructed based on possibilities of the predicates in hitting a message. The possibility of the predicate for a lower internal node in the tree structure hitting the message is higher than that of an upper internal node. Each of the subscription information corresponds to one leaf node in one tree structure, and each of the subscription information corresponds to all information of the predicates in a branch of the leaf node in the tree structure thereof from the root node. The one or more tree structures for matching with the message are stored. | 03-03-2016 |
