20080273626 | SYSTEM AND METHOD FOR PERFORMING BASEBAND PHASE SHIFTING IN A CARTESIAN FEEDBACK SYSTEM - A system and method for performing baseband phase shifting in a Cartesian feedback system includes a forward path for receiving an input baseband signal having two components, and performing up-conversion to output a RF signal; a power amplifier for amplifying the RF signal output from the forward path; and a feedback path for down-converting at least a sample of the output from the power amplifier to a feedback baseband signal comprising two components, and providing the feedback baseband signal to the forward path in order to be summed with the input baseband signal at a summing junction and before the loop filter. The forward path includes a baseband phase shifter for adjusting the baseband signal output from the summing junction in order to compensate for any phase shifts induced in the system. | 11-06-2008 |

20120001694 | ADAPTIVE CARTESIAN LOOP TRANSMITTER FOR BROADBAND AND OPTIMAL LOOP STABILITY ADJUSTMENT - An integrated circuit includes a linearizer circuit in which excessive delay is compensated. The linearizer circuit includes a power amplifier, forward and feedback paths, and a microprocessor. A signal from the power amplifier is routed by the forward path to be transmitted while a portion of the signal to be transmitted is routed back to the power amplifier via the feedback path. The microprocessor applies phase training signals to the forward path. The microprocessor uses the phase training signals to determine the amount of delay in the linearizer circuit and alters the frequency position of poles and zeros in the linearizer circuit to compensate for the delay. The gain of the linearizer circuit is also altered by the microprocessor depending on the measured delay. | 01-05-2012 |

20130024682 | Storage Device and Method for Updating a Shadow Master Boot Record - A storage device and method for updating a shadow master boot record (MBR) are provided. In one embodiment, a storage device is provided having a memory with a first storage area and a second storage area. The storage device receives updated sectors of the shadow MBR from a host device and writes the updated sectors in the second storage area. The storage device determines a highest written sector in the first storage area that is occupied by the shadow MBR. The storage device copies the non-updated sectors of the shadow MBR from the first storage area to the second storage area, wherein only the non-updated sectors up to the highest written sector are copied. Accordingly, any non-updated sectors above the highest written sector are not copied from the first storage area to the second storage area. The storage device then designates the second storage area as storing a current version of the shadow MBR. | 01-24-2013 |

20090003384 | DATA TRANSMISSION SCHEME WITH SCHEDULING OPTIMIZATION FOR PHYSICAL CHANNEL GROUP - A novel apparatus for and a method of optimized data transmission whereby an input data stream is distributed over a plurality of physical channels within a logical channel group. Transmission of data over the channel group appears as transmission over a single logical channel having a bandwidth approximately equal to the sum of the physical channel bandwidths. The physical channels making up the logical channel group may have different bandwidth capacities. The method of data unit distribution among a plurality of physical channels generates several transmission plans for scheduling data units, which may have difference lengths, over the physical channels where the data stream is composed of data units from different sessions. A best plan according to one or more optimization criteria is selected and used for distribution of the data units. The original order of transmission of the data units can be reproduced for each data session at the receiving side without the need for additional fields or modification of existing fields of the data units. | 01-01-2009 |

20150177988 | SYSTEM AND METHOD OF IMPLEMENTING A TABLE STORAGE SUPPORT SCHEME - A data storage device may be configured to update a table used by a host device, such as a table stored at the data storage device. For, example, the data storage device may generate and store an updated version of a portion of the table. A storage location of the updated version of the portion may be tracked using a data structure that corresponds to a second version of the table. The second version of the table may be discarded or made accessible to the host device responsive to an indicator detected by the data storage device. | 06-25-2015 |
