20130033249 | CONTROL OF DELIVERY OF CURRENT THROUGH ONE OR MORE DISCHARGE LAMPS - A process for controlling a current supplied to a load includes, in at least one aspect, detecting input to control a current supplied to a load operated by a driving signal, and in response to detecting the input, modifying the driving signal to control the current supplied to the load, wherein modifying the driving signal comprises alternately applying a first duty cycle and a second duty cycle to the driving signal. | 02-07-2013 |
20130046886 | Controlling a Network Connection Status Indicator - This disclosure describes techniques for restricting activity of a status indicator if a received data unit is determined to be a protocol control unit that is selected for filtering. In one embodiment, a method is described that comprises receiving a data unit from a network, determining whether the received data unit is a protocol control unit, and restricting activity of a status indicator if the received data unit is determined to be the protocol control unit, or allowing activity of the status indicator if the received data unit is determined to be data other than the protocol control unit. | 02-21-2013 |
20130073922 | METHOD AND APPARATUS FOR IMPROVED PERFORMANCE OF ITERATIVE DECODERS ON CHANNELS WITH MEMORY - Systems and methods for improving the performance of iterative decoders on various channels with memory are disclosed. These systems and methods may reduce the frequency or number of situations in which the iterative decoder cannot produce decoded data that matches the data that was originally sent in a communications or data storage system. The iterative decoder includes a SISO channel detector and an ECC decoder and decodes the coded information according to at least one iterative decoding algorithm in regular decoding mode and/or at least one iterative decoding algorithm in error-recovery mode. | 03-21-2013 |
20130114548 | COEXISTENCE AND COLLOCATION OF REMOTE NETWORK AND LOCAL NETWORK RADIOS - A coexistent communication system of a first network device includes a remote network radio. The remote network radio has a remote transmission distance, operates based on remote network protocols, and communicates with a base station using a first communication link corresponding to a first frequency band. A local network radio has a local transmission distance and is collocated with the remote network radio. The local network radio operates based on local network protocols that are different than the remote network protocols and communicates with a second network device using a second communication link corresponding to a second frequency band. A control module at least one of schedules communication on the first communication link and the second communication link and adjusts a transmission parameter of one of the remote network radio and the local network radio. Transmission distance of the remote network radio is greater than transmission distance of the local network radio. | 05-09-2013 |
20130115941 | COEXISTENCE SYSTEM AND METHOD FOR WIRELESS NETWORK DEVICES - A network interface including a radio frequency (RF) system and a media access controller (MAC). The RF system wirelessly communicates with an access point (AP). The MAC includes client modules. A first client module transmits a first signal from a host to the AP via the RF system in accordance with a first wireless communication standard. A second client module transmits a second signal from the host to the AP via the RF system in accordance with a second wireless communication standard. The second client module determines a quality level of the second signal transmitted from the second client module to the AP, and based on the quality level of the second signal, hands off access to the RF system from the second client module to the first client module to allow the first client module to transmit the first signal to the AP via the RF system. | 05-09-2013 |
20130134905 | COLOR MIXING SYSTEM WITH BUCK-BOOST AND FLYBACK TOPOLOGIES - A system includes a first solid-state lamp that generates a first illuminated output having a first color. A second solid-state lamp generates a second illuminated output having a second color. The second illuminated output is mixed with the first illuminated output to generate a third illuminated output having a third color. An inductor or a transformer includes a primary coil and a bias coil. A first circuit includes the primary coil and a first switch. The first circuit supplies power to the first solid-state lamp. A second circuit includes the bias coil and a second switch. The second circuit supplies power to the second solid-state lamp. A control module alters the third color including controlling (i) a state of the first switch to adjust current supplied to the first solid-state lamp, and (ii) a state of the second switch to adjust current supplied to the second solid-state lamp. | 05-30-2013 |
20130142030 | FREQUENCY DOMAIN ECHO AND NEXT CANCELLATION - A cancellation system is disclosed for processing incoming and outgoing signals in a transform domain to create a cancellation signal for reducing or removing unwanted interference. Data is ordered based on Good-Thomas indexing into a two dimensional array in a buffer. The two dimensional array may have l | 06-06-2013 |
20130155146 | DEVICE FOR SERVICING AN INK JET PRINT HEAD ON A HAND HELD PRINTER - A hand-held printer that includes an inkjet array having a plurality of inkjets is disclosed. The hand-held printer may include an inkjet cap sized to cooperatively engage the inkjet array, wherein the inkjet cap is movable between and open position and a closed position, and a plurality of wipers carried by the inkjet cap, wherein each of the plurality of wipers is configured to engage one of the plurality of inkjets as the inkjet cap moves from the open position to the closed position; and wherein each of the plurality of wipers includes a gasket configured to form a seal adjacent to one of the plurality of inkjets. | 06-20-2013 |
20130201853 | Spectrum estimation for low-load LTE signals - A method includes receiving a signal in a communication terminal. A power spectral density, which the signal would have under full-load conditions of a transmitter transmitting the signal, is estimated based on the received signal. An operation is performed in the communication terminal using the estimated power spectral density. | 08-08-2013 |
20130201886 | RATE MATCHING FOR A WIRELESS COMMUNICATIONS SYSTEM - Apparatuses and methods are provided for generating a plurality of redundancy versions using various rate matching algorithms. In some embodiments, a rate matcher is provided that allocates systematic and parity bits to the redundancy versions in a manner that allows all of these bits to be transmitted in at least one redundancy version. In some embodiments, the rate matcher uses a first puncturing algorithm to generate both a first redundancy version and a third redundancy version, but allocates a different proportion of the systematic bits to these redundancy versions. In these embodiments, the second redundancy version may include only bits that were not transmitted in the first redundancy version. | 08-08-2013 |
