| 20110134696 | Flash EEprom System With Simultaneous Multiple Data Sector Programming and Storage of Physical Block Characteristics in Other Designated Blocks - A non-volatile memory system is formed of floating gate memory cells arranged in blocks as the smallest unit of memory cells that are erasable together. The system includes a number of features that may be implemented individually or in various cooperative combinations. One feature is the storage in separate blocks of the characteristics of a large number of blocks of cells in which user data is stored. These characteristics for user data blocks being accessed may, during operation of the memory system by its controller, be stored in a random access memory for ease of access and updating. According to another feature, multiple sectors of user data are stored at one time by alternately streaming chunks of data from the sectors to multiple memory blocks. Bytes of data in the stream may be shifted to avoid defective locations in the memory such as bad columns. Error correction codes may also be generated from the streaming data with a single generation circuit for the multiple sectors of data. The stream of data may further be transformed in order to tend to even out the wear among the blocks of memory. Yet another feature, for memory systems having multiple memory integrated circuit chips, provides a single system record that includes the capacity of each of the chips and assigned contiguous logical address ranges of user data blocks within the chips which the memory controller accesses when addressing a block, making it easier to manufacture a memory system with memory chips having different capacities. A typical form of the memory system is as a card that is removably connectable with a host system but may alternatively be implemented in a memory embedded in a host system. The memory cells may be operated with multiple states in order to store more than one bit of data per cell. | 2011-06-09 |

| 20110134703 | Nonvolatile Memory and Method With Reduced Program Verify by Ignoring Fastest And/Or Slowest Programming Bits - A group of non-volatile memory cells are programmed in a programming pass by a series of incremental programming pulses where each pulse is followed by a program-verify and possibly program-inhibition step. Performance is improved during the programming pass by delayed starting and prematurely terminating the various verify levels that demarcate the multiple memory states. This amounts to skipping the verifying and inhibiting steps of the fastest and slowest programming (fringe) cells of the group. A reference pulse is established when the fastest cells have all been program-verified relative to a first verify level. The starting of what verify level at what pulse will then be delayed relative to the reference pulse. Verifying stops for a given verify level when only a predetermined number of cells remain unverified relative to that given level. Any errors arising from over- or under-programming of the fringe cells are corrected by an error correction code. | 2011-06-09 |

Then, for example, when the same memory cell row is accessed, a voltage level of the power supply line is raised by a coupling capacitance of the word lines. Thus, even in identical-row-access, static noise margin in identical-row-access can be maintained to be as great as that in different-row-access. Therefore, for example, even when a size or the like of a driver transistor is not made larger, deterioration of static noise margin can be suppressed and a circuit area can be made smaller. | 2011-06-09 |

The number of refreshes occurring each refresh cycle will depend upon the number of bits in the subset that are omitted from the row address. The memory cells that are unable to retain data bits are identified by a modified sense amplifier. | 2011-06-09 |

A power measuring unit in the detecting unit measures the respective received powers of the plurality of slots, and an empty slot identifying unit identifies a slot whose received power is less than a threshold value. | 2011-06-09 |
| 20110134790 | METHOD AND DEVICES FOR BIT RATE ALLOCATION FOR POINT-TO-MULTIPOINT MULTIMEDIA COMMUNICATIONS - A method is provided for controlling point-to-multipoint communications. Channel condition information for multiple receivers of a point-to-multipoint group is received. Signal-to-noise ratio distortion is estimated for a point-to-multipoint group on the basis of the received channel condition information and available encoding bit rates. A bit rate allocation providing an optimal overall signal-to-noise ratio for transmission to the point-to-multipoint group is selected. Encoding of content to the point-to-multipoint group is controlled in accordance with the selected bit rate allocation. | 2011-06-09 |
| 20110134791 | BIDIRECTIONAL FORWARDING DETECTION (BFD) PROTOCOL EXTENSION FOR DETECTING RANDOM TRAFFIC DROPPING - A network device receives, via a forwarding path, a sequence of packets, where each of the packets includes a sequence number. The network device extracts the sequence numbers from the sequence of packets, records the extracted sequence numbers, and determines a first number of packets of the sequence of packets that have been dropped on the forwarding path based on the extracted sequence numbers. The network device determines a traffic dropping ratio for the forwarding path based on the first number of the packets of the sequence of packets that have been dropped on the forwarding path. | 2011-06-09 |
| 20110134792 | Method and Apparatus for a Hub in Daisy Chain Configuration - A connector hub comprising a number of cable interfaces is used to allow a number of network devices connected to a network to be connected in a free-form manner, yet still maintain a daisy chain configuration. A cable comprising at least two conductors, wherein the conductors are preferably a twisted pair of copper wire, is used to connect each of the network devices to a cable interface on the connector hub, so that each network device only has a single cable connected to it. The connector hub connects a master or primary network device to the network devices connected by a cable to the cable interfaces of the connector in a daisy chain configuration. | 2011-06-09 |
| 20110134793 | PREVENTING LOOPS ON NETWORK TOPOLOGIES BUILT WITH VIRTUAL SWITCHES AND VMS - A method and apparatus is disclosed for preventing loops on a network topology which includes virtual switches and virtual machines. For example, a virtualization management application may prevent loops from being introduced into a network topology where a virtual machine forwards traffic between any two (or more) virtual network interface cards (vNICs). A method to prevent loops may include receiving a request to create a virtual network interface (vNIC) for a virtual machine (VM) instance on a computing system, and in response to determining that the requested vNIC is to be connected to the same network segment as an existing vNIC of the VM instance, failing the request to generate the requested vNIC. | 2011-06-09 |
| 20110134794 | APPARATUS AND METHOD FOR AUTOMATIC DISCOVERY OF LIGHTING CONTROLLERS - A lighting system controller is provided that is configured to automatically discover lighting controllers. In a particular example, the lighting system controller is configured to scan a network for lighting controllers that match a set of search criteria. According to this example, the lighting system controller is configured to present any such discovered lighting controllers to a user in a user interface. In this example, the user interface includes elements configured to allow a user to designate one or more of the discovered lighting controllers for centralized management. | 2011-06-09 |
