  • Patent number: 11912397
    Abstract: Thermally configurable structural elements (e.g., aircraft components such as an aircraft winglet spar) capable of assuming at least first and second structural configurations are provided whereby the structural element includes an integral actuation mechanism may be formed of sintered shape memory alloy (SMA) particles and sintered non-SMA particles formed by an additive layer manufacturing (ALM) process, such as 3D printing. The ALM process thereby provides by at least one thermally configurable region, and at least one non-thermally configurable region which is unitarily contiguous with the at least one thermally configurable region. The at least one thermally configurable region is capable of assuming at least first and second positional orientations in response to the presence or absence of a thermal input to thereby cause the structural element to assume the at least first and second structural configurations, respectively.

  • Publication number: 20220173317
    Abstract: The generation of entangled photons is provided by two-photon emission by an emission center immersed in an optical microcavity (MC). The MC is designed to reduce or to suppress the emission of single photons at the fundamental emission wavelength (?g) of the emitter and increase the emission for the two-photon emission wavelength (2?g). A reflector is added only to reflect single photons and will not reflect the biphotons.

  • Patent number: 9729266
    Abstract: Services are transmittable via a transport network by using container(s), wherein each container is adapted to transmit data with a specific bandwidth and is multiplexable, according to a dynamic multiplexing structure, to at least another container adapted to transmit data with a higher bandwidth. The network management system selects a container being adapted to transmit data with a first bandwidth out of the number of containers, determines all containers of the number of containers being adapted to transmit data with a bandwidth lower than the first bandwidth, and defines all possible termination points for each determined container. All possible termination points are defined before a service to be transmitted is selected by a user. A number of the possible termination points for each determined container is selected based on a selection scheme in order to provide the selected number of the possible termination points to the user.

  • Patent number: 9698654
    Abstract: An apparatus for controlling a high-power drive device external to a package of a motor drive circuit includes a motor drive circuit. The motor drive circuit includes a driver to control the high-power drive device based on a first reference voltage, a second reference voltage, and a control signal based on a received control signal. A fault circuit generates a failure indicator based on a voltage across terminals of the high-power drive device. A fault condition is based on the failure indicator. A first terminal coupled to the driver charges a node of the high-power drive device over a first length of time in response to an absence of the fault condition and a first level of the control signal. A second terminal coupled to the driver discharges the node over a second length of time different from the first length of time.

  • Patent number: 8829945
    Abstract: A circuit includes a delay circuit, a transition detector, a pre-driver circuit, and a controller. The delay circuit includes an input for receiving a signal and an output for providing a delayed version of the signal. The transition detector is coupled to the input of the delay circuit to detect a transition within the signal and to provide a look ahead signal to a detector output. The pre-driver circuit includes an input coupled to the output of the delay circuit, a control input, at least one signal output, and a plurality of a bias outputs. The controller is coupled to the detector output and to the control input of the pre-driver circuit and is configured to control bias signals on a plurality of bias outputs to selectively increase a driving strength of signals and biases applied to an output stage in response to the look ahead signal.

  • Patent number: 8122251
    Abstract: The invention includes a method and apparatus for preventing phishing attacks. A first method, for informing a user that a remote server is valid, includes receiving a request for information available from the remote server where the request includes an identifier, obtaining a dynamic personal attribute associated with the user using the identifier, and propagating the dynamic personal attribute toward the user, wherein the dynamic personal attribute is adapted for use by the user in validating the remote server. The remote server may be a web server, an authentication server, or any other remote device with which the user may desire to authenticate.

  • Publication number: 20100203901
    Abstract: Location-based services are provided in a communication system comprising a wireless network. In one aspect, information indicative of location of a given mobile user device of the system is periodically collected. The collected location information is processed in a server or other processing device of the system to determine at least one normal pattern of movement of the mobile user device from at least a first location to a second location. An alert is generated if subsequent movement of the mobile user device from the first location to the second location exhibits a significant deviation from the normal pattern of movement. The normal pattern of movement may be used to generate a multidimensional geofence that includes, in addition to a geographic area dimension, at least one additional dimension such as, for example, a speed of movement dimension, a direction of movement dimension, a stop duration dimension, or a related device proximity dimension.

  • Publication number: 20090055238
    Abstract: A meeting location that is “fair” to all the participants may be selected based on at least the travel circumstances and at least two initial criteria by which an optimal meeting location will be selected, at least one of which has values that are determined for each respective one of the meeting participants using at least information derived from the travel circumstances. Note that by “fair” it is generally intended that no participant can reduce his burden without significantly increasing the burden of some other participant. The meeting location may be determined using a multi-criterial approach. A criterion in this context is a particular property of the travel pertaining to a particular user. In the multi-criterial approach, one selects a preference relation based on each of the individual criteria, and the set of non-dominated alternatives is the outcome of the optimization process.
