Receiving control signals and operating separate scan paths with adaptor
Scan architectures are commonly used to test digital circuitry in integrated circuits. The present disclosure describes a method of adapting conventional scan architectures into a low power scan architecture. The low power scan architecture maintains the test time of conventional scan architectures, while requiring significantly less operational power than conventional scan architectures.

Since the low power scan architecture reduces test power consumption, it is possible to simultaneously test more die on a wafer than previously possible using conventional scan architectures. This allows wafer test times to be reduced which reduces the manufacturing cost of each die on the wafer. |

Clustered device dispersion in a multi-tenant environment
Host machines and other devices performing synchronized operations can be dispersed across multiple racks in a data center to provide additional buffer capacity and to reduce the likelihood of congestion. The level of dispersion can depend on factors such as the level of oversubscription, as it can be undesirable in a highly connected network to push excessive host traffic into the aggregation fabric. As oversubscription levels increase, the amount of dispersion can be reduced and two or more host machines can be clustered on a given rack, or otherwise connected through the same edge switch. By clustering a portion of the machines, some of the host traffic can be redirected by the respective edge switch without entering the aggregation fabric. When provisioning hosts for a customer, application, or synchronized operation, for example, the levels of clustering and dispersion can be balanced to minimize the likelihood for congestion throughout the network. |

Trust network to reduce e-mail spam
A trust network database has any number of nodes, each node representing a user e-mail address. Links between nodes represent whether one user trusts another. Trust (that the recipient is trusted) is established when a sender sends an e-mail message to a recipient. The recipient is effectively placed on the white list for the sender. A legitimate e-mail address creates a strong trust link, otherwise it is weak. A spam count tracks by an amount of spam sent by each node. Outgoing e-mail messages are screened to make a determination that the sender trusts the recipient and that information is added to a local or remote trust network. Incoming e-mail messages are first screened to determine that the sender is legitimate. Then, the sender and recipient e-mail addresses are forwarded to the trust network to make a determination as to whether the recipient trusts the sender. A score (based upon number and type of links into or out of a node, the spam count for the node, etc.) for the sender is returned indicating whether or not the e-mail message is likely to be spam. An anti-spam engine is bypassed, used normally, or used aggressively based upon the score. |

The time resolution of the overall ?segmented? time-to-frequency transform can thus be changed by simply adapting the time segmentation to obtain a suitable number of time segments based on which spectral analysis is applied. The overall set of spectral coefficients, obtained for all the segments, provides a selectable time-frequency tiling of the original signal frame. |

Adaptive notch filter
The control of flexible systems is often difficult due to the exact frequencies of the elastic modes being hard to identify. These flexible modes may change over time, or vary between units of the same system. The variation in the modal dynamics may cause a degradation in performance or even instabilities unless compensated for by the control scheme. Controllers designed for these types of systems use notch filters for mode suppression. However variation in the parameters of the flexible modes may cause the need for wide notch filters. An adaptive scheme is proposed which uses an online estimator based on plant parameterization. The scheme may not use probe signals and may not rely on exact parameter identification of the unknown parameters. Instead it may continuously update itself to cancel the effect of the flexible modes by been able to identify the effect of the modal dynamics on the performance of the system. The adaptive notch filter can be designed narrower, adding less phase lag at lower frequencies, thereby allowing an increase in bandwidth and disturbance rejection capability. Simulation and experimental verification of the adaptive mode suppression scheme is given through the use of a laser beam pointing system. The adaptive scheme is compared to a non-adaptive scheme, and is able to decrease the standard deviation of the experimentally measured tracking error by 14% even when the flexible dynamics are unknown. |

Method and apparatus for remote communication using the interpretation of thermoluminescence or photoluminescence signals
A method for remote communication using the interpretation of thermoluminescence or photoluminescence signals uses a property of photoluminescence or of thermoluminescence when it is caused by entangled trapped electrons. In this case, stimulation of deexcitation of trapped electrons by heat or radiation occurs when the deexcitation thermal energy is approximately equal to the trap-emptying energy. Stimulation by a temperature rise of a “master” sample induces luminescence of a remote “slave” “entangled” sample, which is reproduced on lowering the temperature of the “master” sample whatever the distance and the media separating the “master” sample and the “slave” sample. This teaching and its generalization to other forms of stimulation is used by the method of interpreting the quantum reception measurements so as to determine, using a correlation method, the transmission of information or commands. This method is particularly suitable for carrying out communication with submarines, communication in mine galleries, or communication with space probes. |

Passive optical network system
When a neighbor ONU receives a signal with light intensity high enough to secure communication between an OLT and a remote ONU, the light intensity may be excessively high to damage a receiver of the neighbor ONU. In order to avoid such a problem, each ONU is notified of a downstream signal transmission plan (downstream light intensity map) prior to transmission of a downstream signal. Each ONU receives the downstream light intensity map (light intensity transmission schedule of downstream signal) in advance. Thus, the neighbor ONU can block or attenuate an optical signal addressed to the remote ONU, and the remote ONU can determine normal operation even when the remote ONU cannot receive a signal addressed to the neighbor ONU. Thus, the remote ONU can be prevented from issuing a wrong error signal. |

Laser eye safety and fiber receptacle presence detection
Provided herein is a novel approach to simultaneous fiber presence detection and improved laser eye safety of an optical transceiver. The subject optical transceiver is fitted with at least one switch in its receptacle that controls the laser diode and indicates the presence of a fiber (or fibers) within such a receptacle. If a fiber is present within the subject module receptacle, the laser switch is permitted to be “on”, whereas the absence of a fiber will prevent the laser switch from turning on, thereby permitting effective control of the laser at a single point of failure within the entire optical transceiver system. The typical optical transceivers of today exhibit limited optical power output due to eye safety limit criteria. With this novel approach, however, a module's output power can be increased to higher level since the only way a person's eye may be exposed to the laser is the removal of the fiber receptacle from the subject module and once the fiber is absent from the module, the laser turns off and/or put optical transceiver into standby mode automatically to save power. |

Hearing aid, hearing aid system, walking detection method, and hearing aid method
A hearing aid that analyzes a surrounding acoustic environment and automatically switches between a plurality of hearing aid processing reduces noise by limiting directionality, when the user is in a noisy outdoor location. However, in the case where directionality is limited to the front when the user is walking or the like, the user is put in extreme danger because he/she cannot notice sound of danger approaching from behind. Behavior analysis of identifying a walking state of the user is necessary in addition to environmental analysis, but typical walking detection using a sensor as in the case of a pedometer and the like is not applicable to a device worn at an ear such as a hearing aid. On the basis of an occurrence pattern of wind noise when walking, the walking state of the user is identified in the case where pulse-like wind noise occurs repeatedly. This enables walking detection to be performed using an existing structure, with there being no need to provide a sensor or the like. Hence, it is possible to provide a hearing aid that can be safely used even outdoors. |

Systems and methods of timing DTMF tones for telephony control
Control and status information between a mobile device and another device can be signaled over a voice channel using DTMF tones, e.g., a pre-defined sequence of DTMF tones can signal a desired message (more generally, a feature code). Tones sent are separated from each other by a time gap (Tgap timer). If a receiving device does not receive a sequence of DTMF tones that can be matched to stored definitions of feature codes, then the receiving device generates a negative ACK. Also, if the sending device does not receive either negative or positive ACK, then sending device resends all tones of the feature code after a retry delay (Tretry timer).

Client's start preserving locality data in an affinity context, such that later requests for a connection can be routed to the location last visited. The coordinator measures the system over subsequent intervals. If the gradient of the goodness (viz service quality and capacity) is stable or improving, then the coordinator continues to advise subscribers to use the affinity-based technique. Alternatively, if the gradient of the goodness is deteriorating, then the coordinator posts advice to the subscribers to stop using the affinity-based technique for any instance during the next intervals. |

Learning the expiry time of an address binding within an address translation device for an SIP signaling server
A signaling server (SS) comprising means for transmitting SIP signaling messages with a client (T) through a NAT address translation device temporarily binding a public address to the client's private address, including means for receiving registration messages from the client and for sending the client a validity duration, at the end of which it must transmit a new registration message. The invention resides in the fact that if the client is located behind an address translation device, it determines an approximate expiry time for the temporary binding by successively sending test messages after an increasing wait time until the termination of the binding is detected. This approximate time is then used by being transmitted as the SIP validity period. |

Packet relay method and device
A node according to a packet relay method which enables a multicast transfer or broadcast transfer of a packet effectively is provided. When the node receives a packet set with a multicast address or broadcast address as a destination address from a source client, the packet is added with an MPLS label common to destination clients corresponding to the multicast address or all destination clients corresponding to the broadcast address. The packet added with the common MPLS label is transferred over a ring network. When receiving the packet from a ring network, the node removes a common MPLS label from the received packet to be transmitted to destination clients when it detects that the common MPLS label is added to the received packet. |

Systems and methods for overlaid switching networks
An overlaid switching network is derived by overlaying perpendicularly one multistage interconnection network with a second multistage interconnection network. The new network is formed by placing a switching element corresponding to the position of switching elements in either multistage interconnection network. Each switching element in the overlaid network has the ports defined by the two multistage interconnection networks as does its interconnection networks. A special case occurs when the number of rows and columns of the first multistage interconnection network is the number of columns and rows of the second multistage interconnection network, respectively. The overlaid switching networks also inherit their upgradeability from the multistage interconnection networks from which they are derived, such as in the case of a redundant blocking compensated cyclic group multistage network. |
