US09027100B2 Client-side ad caching for lower ad serving latency
Advertisements are served over the Internet to clients on demand. A client module executing on a client device fetches advertisements over the Internet from an advertisement server. The client module stores these advertisements in a cache on the client device. When an application executing on the client device needs to display an advertisement, instead of contacting the advertisement server directly, the application makes a call to the client module. The client module, instead of contacting the advertisement server immediately, determines whether the cache on the client device contains any advertisements that satisfy criteria specified by the application. If the cache does contain advertisements that satisfy the criteria, then the client module provides those advertisements to the application. Otherwise, then the client module requests criteria-satisfying advertisements from the advertisement server at that time, and provides at least one of those to the application.

The file can also contain browser executable instructions that when executed combine the two pieces to re-create the token and send the re-created token to a server to authenticate the user. The client application can forward the URL to the browser, which can direct the browser to the file. The browser can execute the instructions thereby authenticating the user.

US09026704B2 Priority based connection arbitration in a SAS topology to facilitate quality of service (QoS) in SAS transport
A method of priority based connection arbitration in a SAS topology is disclosed introducing a PRIORITY field to an SAS open Address Frame (OAF).

US09026693B2 Method for filtering cached input/output data based on data generation/consumption
An invention is provided for filtering cached input/output (I/O) data. The invention includes receiving a current I/O transfer.

The transfer rate for the ongoing sequential data stream then is calculated and a determination is made as to whether the transfer rate is greater than a throughput associated with a target storage device. The current I/O transfer is cached when the transfer rate is greater than the throughput associated with a target storage device, or is not cached when the transfer rate is not greater than the throughput associated with a target storage device.
US09026692B2 Data throttling circuit and method for a spacewire application
A Data Throttling method duplicates the full-speed transmission of data so that it appears to be transmitting at a 10 Mhz rate. Additional storage elements and multiplexers are added along the data path but this completely eliminates undesirable complexity in the clock tree. In a two-bit application, data is received and transmitted two bits at a time, and yet the output 10 Mhz data rate is maintained. For an even ratio between the system clock rate and the 10 Mhz clock signal rate, bit0 is transmitted for half the time and bit1 is transmitted for the other half of the time. But if the full-speed clock rate is an odd multiple of 10 Mhz, then there will be a “split cycle” including one bit0 and one bit1.
US09026683B1 Command portal for executing non-standard storage subsystem commands
A command portal enables a host system to send non-standard or “vendor-specific” storage subsystem commands to a storage subsystem using an operating system (OS) device driver that does not support or recognize such non-standard commands. The architecture thereby reduces or eliminates the need to develop custom device drivers that support the storage subsystem's non-standard commands. To execute non-standard commands using the command portal, the host system embeds the non-standard commands in blocks of write data, and writes these data blocks to the storage subsystem using standard write commands supported by standard OS device drivers. The storage subsystem extracts and executes the non-standard commands. The non-standard commands may alternatively be implied by the particular target addresses used. The host system may retrieve execution results of the non-standard commands using standard read commands. The host-side functionality of the command portal may be embodied in an API that is made available to application developers.

The server is then queried with a nonce-less query for the full domain name. The server is queried again with a nonce label prepended query for the full domain name to determine if it currently results in the negative reply. The full domain name is flagged as inappropriate for nonce prepending upon determination that querying with a nonce prepended query results in a negative reply and a nonce-less query results in a positive reply.
