Title: Seal pressure relaxation device prior to release of retrievable packer
Inventor: CHRISTOPHER J LIMB
IPC: E21B33/129
Filed: 2016-06-15
Abstract: A retrievable packer has its sealing system unloaded before the slip system is relaxed by separation of slip cones from slips that flank the seal assembly. The mandrel is cut so that the portion above the cut can be raised to take a cone up and away from collet heads which previously were trapped by the cone. The collet heads are disposed between opposed sloping surfaces so that the retraction of the cone from under the heads allows the residual rubber pressure to force the heads toward the mandrel into the space created by relative movement of the mandrel that took the wedge cone uphole. The heads are at ends of fingers having a radially inward bias to further assist retraction of the heads toward the mandrel. With the heads retracted the sealing element stretches out before slip cones are moved relative to the slips.

Title: Methods and devices for updating an uplink contention window size in a wireless communication system
Inventor: GUANG LIU
IPC: H04W74/08
Filed: 2017-05-27
Abstract: Updating an uplink contention window size in a listen before talk process in a wireless communication system (100) such as LTE may be done by the eNB (101) if transport blocks contained in the starting subframe of a reference scheduled burst transmitted by a User Equipment (103) are successfully decoded at the eNB. Otherwise, the User equipment adjusts the contention window size depending on information supplied by the eNB. This information identifies the first subframe in the burst whose transport block the base station was able to successfully decode. Depending on whether the User Equipment was first transmitting before or on the identified subframe, the User Equipment can either increase or reset the contention window size.

Abstract: A multi-function device (MFD, MFP), 112, that can communication with an on-site or on-premise server, 111, and a cloud service. The MFP sends identification information A41 to the cloud service S401, it then receives information which identifies either the server or the cloud as its controller, C44, S403. The MFP then sends an authentication request that includes the authentication information to the controller identified by the controller information, and then receives a response that indicates whether or not the authentication information is accepted. If the controller information identifies the server as the controller, but the server is not available, then the authentication information may be sent to the cloud service, and vice-versa. The MFP may send the identification information to the cloud service at the time of start-up of the multi-function device. The cloud service may associate the sever with a first location and identify the server as the controller if the location corresponds to the location of the MFP.

Title: Signal processing methods for an optical detection system
Inventor: STUART RUSSELL
IPC: G01H9/00
Filed: 2019-10-11
Abstract: The invention provides a signal processing method for a distributed acoustic sensing system (DAS), where a scattered signal 104 that was scattered at a scattering location along an optical path is received and interfered with a local oscillator signal 106 to generate a first carrier signal that is modulated by a phase difference between the local oscillator signal and the scattered signal 108. The first carrier signal is then digitally processed in order to generate a second carrier signal 110 that is modulated by a spatial differential of the phase difference. The spatial differential 112 of the phase difference is directly related to the strain (or acoustic environment) of the optical path at the scattering location, and so enables the strain at the scattering location to be estimated.

Title: Agreements on the blockchain
Inventor: JACK OWEN DAVIES
IPC: G06Q50/18
Filed: 2020-06-17
Abstract: The application relates to using blockchain transactions to record parties’ mutual consent to agreements such as intellectual property licences. A requesting party 401 generates a request transaction Txrequest having an input signed by the requesting party and an output comprising a cryptographic puzzle based on data representing the agreement, such as a hash puzzle based on a hash of the agreement. A confirming party 402 generates a confirmation transaction Txconfirm having an input comprising the data representing the agreement and a reference to the request transaction’s output. For the confirmation transaction to spend the request transaction’s output, both transactions must have used the same data representing the agreement, thus confirming both parties have mutually consented to identical agreements. Alternatively, if the parties were intending to enter into different agreements then the confirmation transaction will fail to unlock the puzzle in the request transaction and the agreement remains unconfirmed. The confirming party may also generate an advertisement transaction Txadvert having an input signed by the confirming party and an output comprising a representation and/or encrypted version of the agreement.
