20150017928 | OVER-THE-AIR TESTING OF WIRELESS DEVICES USING LOG FILES - An over-the-air test system for wireless devices uses log files to simulate realistic time-varying channel conditions and provides channel state information to enable dynamic adaptation to current channel conditions. A signal transmission device transmits test signals to the device under test via a channel emulator. The channel emulator causes the test signals to exhibit channel conditions which vary over time. An over-the-air test chamber in which the device under test is disposed includes multiple antennas which are driven with the test signals from the channel emulator. Channel state information is sent from the device under test to the signal transmission device. The signal transmission device responds to the channel state information by adapting to current channel conditions. | 01-15-2015 |

20090009343 | Programmable Presence Proxy for Determining a Presence Status of a User - A method and apparatus are provided that evaluate a number of different sources of presence information to determine a presence status of a user. The presence status of a user is determined by obtaining presence information from a plurality of presence data stores; translating the obtained presence information from at least one of said presence data stores into a standard format; and determining the presence status of the user based on the obtained presence information. Presence information can also be based on user-specified rules. Presence information is obtained from a number of presence data stores and the presence status of a user is determined based on one or more rules that are applied to the obtained presence information. The rules may include, for example, aggregation rules that determines the presence status based on one or more of the obtained presence information or filter rules that determine who may receive the presence status. | 01-08-2009 |

20100192211 | Revocable Object Access - Techniques are described to provide revocable object access. In an implementation, a user may provide content and an object (e.g., a picture) to be published with the content. The object is uploaded to a storage location, and a uniform resource locator (URL) that includes a token is generated for the object. The token is registered in an access control list (ACL), and token permission settings in the ACL are utilized to control access to the object. The URL may be embedded in the content. When a viewer requests the content, the object may be retrieved from the storage location using the URL. The user may revoke access to the object by changing the token permission settings in the ACL. | 07-29-2010 |
