Title: A client-server computer system
Inventor: Shahzaib Tahir
IPC: G06F16/33
Filed: 2019-01-10
Abstract: A client-server system 10 for a client 12 to search for a keyword in at least partially homomorphically encrypted documents 18 stored in a server 14. The client applies probabilistic symmetric encryption to a keyword to form a first result. The client applies deterministic symmetric encryption to the keyword, then computes a modular inverse of the deterministically encrypted keyword, and then applies at least partially homomorphic encryption to the modular inverse deterministically encrypted keyword to form a second result. The client uses a session key to hash the first result to form a hash result. The client combines the first result and second result to form a third result, and subsequently encrypts the third result and the hash result using a private key to generate the search query. The client sends the search query which is received by the server. The server identifies at least one identifier of at least one document of the at least partially homomorphically encrypted documents including the keyword by decrypting, using a public key, a product of the search query and the hash result. The server sends the at least one identifier in encrypted form to the client, which decrypts said identifier.

Title: Vehicle
Inventor: IAN GORDON MURRAY
IPC: B62D37/02
Filed: 2019-08-13
Abstract: A vehicle 10, for example a car, has an upper surface 14 and an under surface 18, where upper surface 14 has an aperture 46 and under surface 18 has at least one aperture 40a, 40b, and where vehicle 10 has upper ducting 36 and lower ducting 40 within the bodywork and communicating with the apertures. The upper and lower ductings 36, 40 lead to a fan 30 configured to selectively draw air through the respective ductings. A control unit receives information as to the vehicle dynamic state, for example speed, g-force or attitude, so that, depending on the state, air is drawn through the lower ducting 40 or through the upper ducting 36. This may allow a choice between enhanced levels of down force on the one hand, and low drag on the other, for example the vehicle may be optimised for low drag during high speed straight-line driving, when tight cornering is unlikely, and optimised tor greater downforce when lateral grip is more likely to be needed.

Title: An apparatus and method for controlling access to security modules
Inventor: PAUL JAMES REID
IPC: H04W60/00
Filed: 2019-09-24
Abstract: A technique is provided for controlling access to security modules. An apparatus has a first interface circuitry 15 for establishing connections with a plurality of security modules 20, wherein at least one security module in the plurality of security modules has a different owner to at least one other security module in the plurality of security modules. Second interface circuitry 35 is then used to establish communication with a plurality of subscription management servers 45. A storage stores ownership-based access control information for the plurality of security modules, where that information identifies the owner of each security module and which subscription management servers are allowed access to the security modules of each owner. Access control circuitry is then responsive to a request for a given subscription management server to have access to an identified security module, to reference the ownership-based access control information in order to determine whether to allow the given subscription management server to access the identified security module. Each security module could be one of an embedded universal integrated-circuit card (eUICC) and an integrated UICC (iUICC) capable of storing a plurality of subscription profiles. Such an approach allows multi-tenanted systems to be provided.

Filed: 2020-04-24
Abstract: A surgical robot comprising: an arm comprising: a series of joints extending from a base to a terminal end for attaching to a surgical instrument for inserting through a port into a patient’s body to a surgical site, the series of joints comprising a first set of joints, where for each joint of the first set, there’s a configuration of the arm for which that joint experiences a gravitational torque or force and a movement of that joint complying with the gravitational torque or force would cause the surgical instrument to advance into the patient’s body towards the surgical site; and joint motors for driving the series of joints; and a controller to send drive signals to drive the joint motors, where the controller is configured to, in response to detecting a power loss, send drive signals to the joint motors to hold the position of each joint of the first set against gravity 1202, thereby preventing the surgical instrument advancing into the patient’s body towards the surgical site due to movement of one or more joints of the first set under gravity. Preferably, the detected power loss is loss of surgical robot arm power from a back-up battery supply.

Abstract: Electric current is induced in coils of an axial flux generator by plural magnetic fields from two magnetic annuli rotating about a common axis either side of a static coil annulus (fig 1,15). Each coil has a shape defined by first and second positions 703a, 703b on opposite sides of the shape, that are at a radius from the innermost position 701 that is at least 60% of the difference in radius between the innermost position 701 and the outermost position 702, the radii being measured from the common axis. A portion 710 of the shape that is outward of the two positions is bounded by two lines 712, 713 having a common radius that is 0.625 times the maximum dimension 704 of the shape perpendicular to a radius, the outer line being longer than the inner line. The common radius of the two lines 712,713 may be 0.575, 0.55, 0.52 or 0.51 times the maximum dimension 704 of the shape perpendicular to a radius. The shape of the coils and a magnetic profile may be designed to maximise electromotive force (emf) generated in the radial outward portion of the coils using finite element analysis.

Title: Target magnet mechanism for proximity switch
Inventor: MICHAEL SIMMONS
IPC: H03K17/97
Filed: 2019-01-25
Abstract: A target magnet mechanism for a proximity switch. The target magnet mechanism includes a plurality of magnets disposed in an alternating magnetic pole configuration forming a narrowed, polarity reversing magnetic field. A center magnet has a magnetic polarity opposite the magnetic polarity of a sensing magnet of the proximity switch. A flanking magnet includes a magnetic polarity opposite the magnetic polarity of the center magnet and the same as the sensing magnet. So configured, the plurality of magnets trigger the proximity switch to an activated state by pulling on a magnetic field of the proximity switch via the opposed polarity of the center magnet and the sensing magnet. In addition, the plurality of magnets release the proximity switch back to an unactivated state by pushing on the magnetic field of the proximity switch via the same polarity of the flanking magnet and the sensing magnet.
