METHOD FOR RENDERING FLUID |
USA
|
Abstract
A method for rendering fluid is provided. First, state information of a plurality of fluid particles is provided, wherein the state information records whether the fluid particles are located above or under a fluid surface and the interactions between the fluid particles and a terrain or the dynamic objects. Then, whether to render the fluid particles in a direction facing a viewer or in a direction parallel to the flow direction is determined according to the information that whether the fluid particles are located above or under the fluid surface. Next, the fluid particles are rendered as a plurality of two-dimensional metaballs according to the interactions between the fluid particles and the terrain or the dynamic objects, and these metaballs are stacked to reconstruct the fluid.

RESOURCE ALLOCATION APPARATUS, SUBSCRIBER STATION, RESOURCE ALLOCATION METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM |
USA
|
Abstract
The present invention relates to a resource allocation apparatus, subscriber station, resource allocation method, and non-transitory computer readable medium thereof. The resource allocation apparatus may know the unoccupied partition of the wireless network resource and allocate the unoccupied partition to the SS of the femtocell network. Thereby, the SS of the femtocell network will not occupy the same network resource of the macro BS or other femto SS, and interference of between femtocell and macrocell or other femtocell is reduced effectively.

METHOD AND APPARATUS FOR EFFICIENT DATA BROADCAST WITHIN BEACONING NETWORK |
USA
|
Abstract
A wireless communication apparatus, system, method and computer readable medium therefor for transmission between a parent node and a child node are provided. The child node transmits a first packet to the parent node via point-to-point transmission. When the parent node tries to transmit a second packet to the child node, a synchronization signal is transmitted first and then the second packet is transmitted to the child node via broadcast transmission after a certain period. If the child node fails to receive the second packet during the certain period, the child node sends a signal to the parent node. The parent node re-transmits the second packet to the child node via point-to-point transmission.

PEER-TO-PEER COMMUNICATION FOR INSTAT MESSAGING BETWEEN DIFFERENT INSTANT MESSAGE APPLICATION TYPE |
USA
|
Abstract
An instant message is received from a first daemon corresponding to a first instant messaging application type originating with a first client, and transmits the instant message to a second daemon corresponding to a second instant messaging application type originating with a second client. A third daemon receives the instant message using communication protocol corresponding to the first instant messaging application type. A message switching unit acquires the second instant messaging application type corresponding to the third daemon identity, and acquires a second daemon identity. A fourth daemon transmits the instant message to the second daemon corresponding to the second daemon identity using communication protocol corresponding to the second instant messaging application type.

METHOD AND SYSTEM FOR DYNAMICALLY DETERMINING WEB RESOURCE TO BE LOADED AND SAVING SPACE |
USA
|
Abstract
A method for dynamically determining web resource to be loaded and saving space is provided which determines whether to download a network resource according to a current network bandwidth and available memory space. When a user uses an embedded device in a wireless network environment to download a web-page, the browser only downloads a small part of the network resource to present, and if the user desires to download all network resources, he or she can select to download all network resources, so as to save the download time.

METHOD OF DETECTING THE TYPE OF NETWORK ADDRESS TRANSLATOR |
USA
|
Abstract
A method of detecting the type of network address translator utilizes the SIP standard structure and protocol between a user agent and a call manager; wherein after receiving a request message sent from the user agent, the call manager uses different step to reply, and then detects the network type of NAT according to the reply message sent by the user agent.

MEDIUM ACCESS CONTROL METHODS WITH QUALITY OF SERVICE AND POWER MANAGEMENT FOR WIRELESS LOCAL AREA NETWORKS |
USA
|
Abstract
A MAC method has three procedures: a prioritization procedure, a collision resolution procedure, and a polling procedure. The prioritization procedure employs the handshaking method to ensure that a high priority station can join the polling list earlier than a low priority station. The collision resolution procedure employs a tree-splitting algorithm to ensure all active stations that underwent the prioritization period can join the polling list in a bounded time. In the polling procedure, the AP allocates the TXOP for each admitted station and schedules the transmission order of all admitted stations. In addition, the AP broadcasts the schedule information in the V-POLL frame. A power-saving station can wake up at the start of the contention-free period. To conserve power, on inspecting the V-POLL frame, if a PS station finds that it cannot transmit nor receive data frames during the polling period, then that station may return to the doze state.

METHODS AND SYSTEMS OF DYNAMIC CHANNEL ALLOCATION FOR ACCESS POINTS IN WIRELESS NETWORKS |
USA
|
Abstract
A method for dynamic channel allocation for access points in wireless networks. Communication information of wireless devices is gathered. A network topology formed by the wireless devices is derived according to the communication information. Switch channel indexes for each wireless device are calculated according to the communication information and network topology. Desired wireless devices for switching channels are determined according to the switch channel indexes.

METHOD OF BUILDING A LOCATING SERVICE FOR A WIRELESS NETWORK ENVIRONMENT |
USA
|
Abstract
A method of building a locating service for a wireless network environment includes: an environment input step, a detection point calculation step, a measuring step and an assumed non-detected position point step to find measured position points and to measure a four-directional signal strength of the measured position point. By assuming signal strengths of non-detected position points, an entire positioning system can be established. A measuring process includes a portable device signal measuring step, a position point calculation step, and a signal feed back step to send the corresponding position information to the portable device to provide information to a user.

ROUTING METHOD AND SIP SERVER USING THE SAME |
USA
|
Abstract
A routing method. When implemented in a network system, the routing method ameliorates problems of media stream routing through a network address translation (NAT) device. First, whether a first terminal will correspond to different public address-and-port information for receiving media stream packets from a second terminal opposite to the first terminal after receiving different requests is determined. The first and second terminals comprise a caller and a callee which are capable of communicating in SIP protocol. The public address-and-port information is recorded as source information in media stream packets initiated by the requests. Media stream packets from the first terminal are relayed based on the determination.
