20150103595 | BIT LINE AND COMPARE VOLTAGE MODULATION FOR SENSING NONVOLATILE STORAGE ELEMENTS - In a block of non-volatile memory, bit line current increases with bit line voltage. For current sensing memory systems, average bit line current during a sensing operation need only exceed a certain threshold amount in order to produce a correct result. For the first word lines being programmed in a block, memory cells connected thereto see relatively low bit line resistances during verify operations. In the disclosed technology, verify operations are performed for these first programmed word lines with lower verify bit line voltages in order to reduce excess bit line current and save power. During read operations, this scheme can make threshold voltages of memory cells connected to the lower word lines appear lower. In order to compensate for this effect, various schemes are disclosed. | 2015-04-16 |

20150103629 | CORRECTION OF DETECTING DEPTH AND CALCULATION OF SPEED OF MOVING OBJECTS BASED ON TIME OF FLIGHT OF ULTRASOUND PULSES - During transmission, speed of ultrasound pulses gradually reduces due to their energy loss from acoustic impedance.

The density and sound speed in PZT elements decide the frequency of the ultrasound pulses, which can be used to increase the detecting depth for a high frequency ultrasound. Moving objects can change speed of reflected ultrasound pulses, which change their TOF and TOF shift.

Embodiments of the present invention are applied to the processing of the packet. | 2015-04-16 |
20150103689 | SUPPRESSION OF INTERFERENCES BETWEEN CELLS - An interference power measuring circuit in a base station measures the interference power in a cell that the base station belongs to. When the measured interference power is larger than a predetermined value, the transmitter in the base station transmits the interference information for each frequency used in the FDMA communication system to a base station in a neighboring cell. The base station in the neighboring cell instructs user equipment that communicates the base station to reduce a transmission power. | 2015-04-16 |
20150103690 | TRANSMISSION APPARATUS AND TRANSMISSION METHOD USING A PLURALITY OF DIVIDED FREQUENCY BANDS IN A COMMUNICATION BAND - A radio communication apparatus capable of alleviating a burden in setting a transmission format and suppressing increases in the scale of the apparatus. In this apparatus, space multiplexing adaptability detection section detects space multiplexing transmission adaptability for divided bands obtained by dividing a communication band to which Ns subcarrier signals belong in multicarrier transmission and to which a plurality of subcarrier signals belong, and outputs the detection results. Transmission format setting section sets a transmission format when carrying out radio transmission based on the detection results from space multiplexing adaptability detection section. | 2015-04-16 |
20150103691 | METHOD AND APPARATUS FOR MULTI-INSTANCE CONTROL PLANE FOR DYNAMIC MPLS-TP TUNNEL MANAGEMENT VIA IN-BAND COMMUNICATION CHANNEL (G-ACH) - A dynamic tunnel management and signaling control plane protocol message is encapsulated in a data plane protocol encapsulating packet and communicated through a data plane channel to a destination label switching node. The destination label switching node extracts information from the dynamic tunnel management and signaling control plane protocol message from the data plane protocol encapsulating packet in the data plane, and performs a dynamic tunnel management process based on the extracted information. Optionally, the data plane channel is a generic associated channel (G-ACH). | 2015-04-16 |
20150103692 | Host Traffic Driven Network Orchestration within Data Center Fabric - Presented herein are techniques to handle data packets received at a top-of-rack (ToR) switch in an underlay network hosting one or more tenant networks. The underlay network may comprise a plurality of ToR switches each connected to each of a plurality of spine switches. The data packet may be received from a virtual machine in a tenant network, and have a header with a data packet identifier. A mobility domain identifier may be determined that corresponds to the network portion within which the virtual machine can be migrated. The mobility domain may be configured on the ToR switch on a per-port basis based on the virtual machine connected to the ToR switch port. A unique identifier may be formed based on the data packet identifier and mobility domain identifier. Using this unique identifier, provisioning information may be obtained for the tenant network on the ToR switch. | 2015-04-16 |
20150103693 | GATEWAY ADAPTED FOR VOD - Some embodiments of the present application relate to the field of gateways for internet access, associated video service decoders and the methods for broadcasting video content by an operator through such a gateway intended for such a decoder. A virtual MAC address is dedicated to VOD on the decoder. This address is then recognized by the gateway. The gateway implements a direct circuit directly directing the traffic related to this virtual address between the interface for accessing the communications network and the gateway physical port to which the decoder is connected. Advantageously, the circuit is dynamically configured by intercepting the DHCP request used to configure this virtual address. | 2015-04-16 |
