Title: Method for estimating the frequency of a time signal
Inventor: SCHEPPACH FRANK
IPC: G01R23/16
Filed: 1999-01-20
Abstract: The invention relates to a method for estimating the frequency of a time signal by means of a discrete Fourrier transformation and interpolation between support points of the DFT spectrum. According to said method, the hamming window is used in a known manner for filtering and the interpolation is carried out according to a mathematically calculated solution. The method makes use of the fact that a function of the third degree which can serve as a correction distance has a clear solution within the definition range of the amount ratio between a secondary maximum and a primary maximum of the DFT spectrum. The correction distance is calculated according to this solution on the basis of the ratio of the secondary maximum and the primary maximum.
Patent CA-2320307-A1 (CA)
Title: Object hashing with incremental changes
Inventor: KLOTS BORIS
IPC: G06F9/46
Filed: 1999-12-06
Abstract: A method and system are provided for reconfiguring a multiple node system after an epoch change in a manner that reduces the overhead and system unavailability typically incurred during reconfiguration. A resource-to-master mapping is established using the combination of a resource-to-bucket hash function and a buket-to-node hash function. The resource-to-bucket hash function is not changed in response to an epoch change. The bucket-to-node hash function does change in response to epoch changes. Techniques are disclosed for adjusting the dynamic bucket-to-node hash function after an epoch change in a manner that load balances among the new number of nodes in the system. Further, the changes to the bucket-to-node assignments are performed in a way that reduces the number of resources that have to be remastered. In one embodiment, only those resources that lose their masters during an epoch change are assigned new masters during an initial reconfiguration. Load balancing is then gradually achieved by migrating resources after the system has been made available. The old masters of resources forward access requests to new masters of resources once they have transferred the master resource objects for the requested resources. In addition, techniques are disclosed for migrating resources from a node in anticipation of a planned shutdown of the node.

Abstract: A television game machine includes a housing. The housing has an air intake and air exit in side surfaces, and forms an air flow passage in a space of air flow on a line connecting between the air intake and the air exit. A heat-radiating member formed with heat-radiating fins is attached in a state electrically insulated from a semiconductor device mounted on the printed board in order to transfer heat generated from the semiconductor device. The heat-radiating member is arranged related to the semiconductor device and printed board such that the heat-radiating fins are along the air flow passage. A heat-radiating fan is arranged between at least one of the air intake and the air exit and one end of the heat-radiating member. The heat-radiating fan, when ambient air is taken through the air intake and caused to flow through the grooves between the heat-radiating fins of the heat-radiating member to be released outside through the air exit, releases the heat dissipated from the heat-radiating fins together with flowing air to an outside. Thus, the heat generated by the semiconductor device is released to the outside of the housing.

IPC: H04N7/26
Filed: 1999-06-24
Abstract: A method and apparatus for composing and presenting multimedia programs using the MPEG-4 standard at a multimedia terminal (100). A composition engine (120) maintains and updates a scene graph (124) of the current objects, including their relative position in a scene and their characteristics, and provides a corresponding list of objects (126) to be displayed to a presentation engine (150). In response, the presentation engine begins to retrieve the corresponding decoded object data that is stored in respective composition buffers (176, . . . 186). The presentation engine assembles the decoded objects to provide a scene for presentation on output devices such as a video monitor (240) and speakers (242), or for storage. A terminal manager (110) receives user commands and causes the composition engine to update the scene graph and list of objects accordingly. The terminal manager also forwards the information contained in the object descriptors to a scene decoder (122) at the composition engine.
