20130121406 | 8-POINT TRANSFORM FOR MEDIA DATA CODING - In general, techniques are described for implementing an 8-point discrete cosine transform (DCT). An apparatus comprising an 8-point discrete cosine transform (DCT) hardware unit may implement these techniques to transform media data from a spatial domain to a frequency domain. The 8-point DCT hardware unit includes an even portion comprising factors A, B that are related to a first scaled factor (μ) in accordance with a first relationship. The 8-point DCT hardware unit also includes an odd portion comprising third, fourth, fifth and sixth internal factors (G, D, E, Z) that are related to a second scaled factor (η) in accordance with a second relationship. The first relationship relates the first scaled factor to the first and second internal factors. The second relationship relates the second scaled factor to the third internal factor and a fourth internal factor, as well as, the fifth internal factor and a sixth internal factor. | 05-16-2013 |

In one aspect a wireless power transmitter is provided. The wireless power transmitter includes a transmit circuit including a transmit coil. The transmit circuit is configured to wirelessly transmit power to a wireless power receiver. The wireless power transmitter further includes a communication circuit configured to receive information based on a temperature measurement of the wireless power receiver. The wireless power transmitter further includes a transmit controller circuit configured to adjust an operating point of power transfer based on the information. | 09-06-2012 |
20120142378 | METHOD AND APPARATUS FOR DETERMINING LOCATION OF MOBILE DEVICE - A method for determining a location of a mobile device with reference to locations of a plurality of reference devices is disclosed. The mobile device receives ambient sound and provides ambient sound information to a server. Each reference device receives ambient sound and provides ambient sound information to the server. The ambient sound information includes a sound signature extracted from the ambient sound. The server determines a degree of similarity of the ambient sound information between the mobile device and each of the plurality of reference devices. The server determines the location of the mobile device to be a location of a reference device having the greatest degree of similarity. | 06-07-2012 |
20110026432 | SYNCHRONOUS INTERFACE FOR MULTI-RADIO COEXISTENCE MANAGER - Systems and methodologies are described herein that facilitate a synchronous bus architecture for multi-radio coexistence associated with a wireless device. As described herein, a system of buses operating in a synchronous manner, combined with optional on-chip and/or other supplemental buses, can be utilized to couple respective radios and/or other related endpoints to a coexistence management platform, thereby facilitating management of coexistence between multiple radios in a unified and scalable manner. As further described herein, communication between a coexistence manager and its respective managed endpoints can be facilitated through the use of a single bus or multiple buses (e.g., external buses, on-chip and/or other internal buses, etc.) that can operate concurrently and/or in an otherwise cooperative manner to facilitate expedited conveyance of radio event notifications and their corresponding responses. | 02-03-2011 |
20100278216 | METHOD AND SYSTEM FOR INTER-CELL INTERFERENCE CANCELLATION - Systems and methods for inter-cell interference cancellation are provided. In one aspect of the disclosure, an apparatus is provided. The apparatus comprises a cell computation unit configured to compute receive chips for a first interfering cell and a subtraction unit configured to remove the computed receive chips for the first interfering cell from received chips at a receiver. The apparatus further comprises a processing unit configured to process the received chips with the computed receive chips for the first interfering cell removed into received symbols and a detection unit configured to detect user symbols for a target cell from the received symbols. | 11-04-2010 |
