  • Publication number: 20250116171
    Abstract: System and methods for efficient sealing within an annulus outside the casing of a subterranean wellbore using annulus intervention insertion system are disclosed. Some examples describe a system that includes a magnetorheological cementitious material and a magnetic field induced by electromagnet provided inside the wellbore. Efficient cementing is achieved by holding the magnetorheological cementitious material to in the desired position by the magnetic forces of the electromagnet; and allowing the magnetorheological cementitious material to harden and set in the annulus.

  • Patent number: 12264574
    Abstract: A visual inspection system intended for inspection of the difficult to reach lateral wellhead ports and annulus is provided. The inspection of the annular ports is carried out prior to running a simplified annulus intervention system. The imaging assembly of the visual inspection system of the present invention can be manoeuvred to view and capture images of remote, inaccessible, difficult to reach locations in the lateral access port and the adjacent annular region, prior to running of annulus intervention system, thus enhancing the success rate of carrying out annulus interventions and increasing safety by increasing the efficiency of well intervention operations and reducing the risk of unintended incidents.

  • Patent number: 10295112
    Abstract: A leveling pad for stabilizing a device is provided. The leveling pad comprises a metal base having a socket configured to receive a portion of the device and a liner coupled to the metal base and being configured to cold flow into a profile of a floor surface when a weight of the device is applied to the leveling pad. The liner may be of a polymer, such as vinyl. The liner is further configured to plastically deform into the profile of the floor surface. The plastic deformation is designed to increase a magnitude of a shear force or a tensile force required to separate the liner from a portion of the floor surface into which it is configured to plastically deform.

  • Patent number: 10079017
    Abstract: An electronic device may operate in different modes of operations. In a first mode of operation, the electronic device may receive user speech via a microphone, generate audio data that represents the user speech, and then send the audio data to one or more remote computing device for analysis. In a second mode of operation, the electronic device may receive user speech via the microphone, generate audio data that represents the user speech, and then analyze the audio data using speech processing. In some instances, the electronic device may operate in the first mode of operation and/or the second mode of operation based on whether the electronic device is receiving power from an external source.

    Abstract: An electronic device may operate in different modes of operations. In a first mode of operation, the electronic device may receive user speech via a microphone, generate an audio signal that represents the user speech, and then send the audio signal to one or more remote computing device for analysis. In a second mode of operation, the electronic device may receive audio data from a peripheral device and then output audible content represented by the audio data. In some instances, the electronic device may operate in the first mode of operation and/or the second mode of operation based on whether the electronic device can communicate with the one or more computing devices over a wide-area network.

  • Patent number: 9787530
    Abstract: A recovery network may provide communication recovery and backup services to an organization. The organization may comprise an internal network, such as Internet Protocol (IP) network. An alternative communication path communicatively couples communication devices of the organization to a public communication network. A recovery application operates on devices of the organization. The recovery network receives periodic availability indicators from devices within the organization. The recovery network identifies a communication endpoint of the intended recipient of a communication request using the availability indicators.

  • Patent number: 9633661
    Abstract: A portable music device may operate in response to user speech. In situations in which the music device is operating primarily from battery power, a push-to-talk (PTT) button may be used to indicate when the user is directing speech to the device. When the music device is receiving external power, the music device may continuously monitor a microphone signal to detect a user utterance of a wakeword, which may be used to indicate that subsequent speech is directed to the device. When operating from battery power, the device may send audio to a network-based support service for speech recognition and natural language understanding. When operating from external power, the speech recognition and/or natural language understanding may be performed by the music device itself.

  • Patent number: 8537663
    Abstract: A recovery network may provide communication recovery and backup services to a carrier having a service area. The recovery network may be configured to communicatively couple the carrier to the public communication network (PCN) using one or more alternative communication paths, such as a satellite network. The alternative communication paths may couple the recovery network to the carrier independently of the PCN. When the carrier detects a failure in its uplink to the PCN, it may failover to the recovery network, which may service the communication requests using the alternative communication path(s). Similarly, the recovery network may be used to service inbound communication requests directed to the carrier or other organization, such as a Public Safety Answering Point (PSAP). When used with a PSAP, the recovery network may be configured to access and/or provide metadata related to inbound communication requests.

  • Patent number: 8310918
    Abstract: A recovery network may provide communication recovery and backup services to an organization. The recovery network may be communicatively coupled to the existing communication infrastructure of an organization via one or more alternative communication paths. The alternative communication paths may couple the recovery network to the organization independently of a public communication network. Upon activation of recovery services, the recovery network may receive communication requests directed to the organization from the public communication network. The recovery network may service one or more of the requests using one or more of the alternative communication paths. Similarly, the recovery network may service outbound communication requests originating at the organization over an alternative communication path. Communication requests may be backed up (e.g.
