  • Patent number: 7653706
    Abstract: A dynamic image delivery system receives a client request for an image at an image caching server. The image caching server measures the client's network access speed and looks for an appropriate pre-rendered copy of the requested image that is rendered for the client's network access speed in local storage. If the appropriate rendered copy is found, then the image caching server sends the rendered image to the client. If it is not found, then the image caching server dynamically renders a copy of the image and sends it to the client.

  • Publication number: 20100005175
    Abstract: A method and mechanism for a distributed on-demand computing system. The system automatically provisions distributed computing servers with customer application programs. The parameters of each customer application program are taken into account when a server is selected for hosting the program. The system monitors the status and performance of each distributed computing server. The system provisions additional servers when traffic levels exceed a predetermined level for a customer's application program and, as traffic demand decreases to a predetermined level, servers can be un-provisioned and returned back to a server pool for later provisioning. The system tries to fill up one server at a time with customer application programs before dispatching new requests to another server. The customer is charged a fee based on the usage of the distributed computing servers.

  • Publication number: 20090259853
    Abstract: A dynamic multimedia fingerprinting system is provided. A user requests multimedia content from a Web cache server that verifies that the user is authorized to download the content. A custom fingerprint specific to the user is generated and dynamically inserted into the content as the content is delivered to the user. The custom fingerprint can be generated on the Web cache server or at the content provider's server. The system allows a content provider to specify where the custom fingerprint is inserted into the content or where the fingerprint is to replace a placeholder within the content.

In one embodiment, an exemplary apparatus includes a thermal noise generator configured to generate thermal noise as a calibrating signal into an input of an Rx path of an RF integrated circuit. The apparatus also includes a calibrator configured to first measure an output signal from an output of the Rx path, and then adjust a gain of the Rx path based on the thermal noise. In one embodiment, the thermal noise generator further includes a termination resistance and/or impedance.

  • Publication number: 20050152321
    Abstract: A method for autonomously and dynamically optimizing transmission power of an endpoint in a wireless network includes the step of monitoring a received signal strength, a received signal quality and a transmission error rate of a signal transmitted between an access point in the wireless network and the endpoint at a given transmission power and transmission speed. The method also includes the steps of reducing the transmission power when the received signal strength, the received signal quality and the transmission error rate are at respectively acceptable operating levels and then monitoring the transmission error rate of the signal transmitted at the reduced transmission power level. The method further includes the step of adjusting one of the transmission power or the transmission speed based on whether the transmission error rate of the signal transmitted at the reduced transmission power is still at its respective acceptable operating level.
