Title: Method and apparatus for transmitting a continuous radar wave
Inventor: ALAIN CAILLERIE
IPC: G01S13/38
Filed: 2015-12-21
Abstract: The radar generates a base signal S1 which is mixed with a frequency ramp S2 to produce a signal S3 having two spectral components whose frequency ramps are symmetrical mirrors of each other. Instead of filtering one of these sidebands out, both are used. The dual frequency signal S3 is mixed with a carrier signal S4 and transmitted. A receiver 230 down-converts 233 the received signal, filters 241 it into its frequency components, mixes it with the dual frequency signal S3, filters 243 a component and digitises 245 this. A triangular waveform may result in the two components crossing over each other (Fig. 5C). A plurality of such pairs of frequencies, each centred on a different central frequency, may be used (Fig. 7A, 8A, 8B).

Title: Systems and methods for intersection assistance using dedicated short range communications
Inventor: CYNTHIA M NEUBECKER
IPC: H04W84/00
Filed: 2017-04-18
Abstract: Vehicle 104 uses dedicated short range communication (DSRC) transceiver 124 to receive safety messages from other vehicles 102, 106. An intersection assistor of a vehicle 104 determines the likelihood there will be space 130 on the other side of the intersection. A recommendation for proceeding to drive through the cross-road is displayed based on the likelihood. Safety messages may comprise the speed, heading and location of one of the other vehicles. The suggestion to drive through the junction may be based on the likelihood calculated from speed and heading values, and a stopping distance, determined by the intersection assistor. Additional safety messages may be received from a traffic signal 110 (vehicle-to-infrastructure, V2I) comprising timings of traffic lights. The recommendation may be based on the computed likelihood and whether the lights are changing from green to red. Other aspects concern a method and a computer readable medium. The invention aims to prevent tailback congestion obstructing intersections by deciding if there is an opening.

Abstract: In order to reduce aerodynamic perturbations in a secondary channel, for example a bypass duct, of an aircraft dual flow turbine engine, the invention provides a thrust reverser system 40 comprising a thrust reverser cascade 46 and a reverser door. The thrust reverser system is configurable between an active configuration and an inactive configuration. The reverser door comprises a first segment 51a and a second segment 50b which, in the inactive configuration, are folded relative to each other and accommodated in an accommodation space 60 along with the thrust reverser cascade. At transition from an inactive configuration to an active configuration a mobile outer nacelle fairing 28 is displaced rearward driven back by a rearward displacement of the thrust reverser cascade via at least one of the reverser door segments. The two reverser door segments, in the active configuration, are deployed into a position where they are blocking the bypass duct. One of the two gate segments forces air from the secondary channel through a grating of the thrust reverser cascade, and the other prevents air leaving through the grating from recirculating in the bypass duct. The two gate segments, in the active configuration may be aligned.

Title: Tyre pump X4 2018
Inventor: EDWARD JOHN O'CONNOR
IPC: B60C29/04
Filed: 2018-03-28
Abstract: A pump 10 installed on the inside surface of the tread of a tyre 64 has a base plate 12 attached to the inside surface of the tread. Restraints 62 attach the base plate to a compression plate 56. Positioned between the base plate and the compression plate is a compressible chamber 26, with an inlet and an outlet, containing a fluid such as air. The weight of the tyre and vehicle causes a flat contact patch at the bottom of the tyre where the tyre contacts the road. As the tyre rotates, the pump traverses the contact patch and the base plate is deformed, or flattened. As the curvature of the base plate is reduced, the anchor points 20 to which the restraints are attached move away from the corresponding ends of the compression plate, pulling the compression plate towards the base plate and compressing the compressible chamber, ejecting air threrefrom. The outlet of the compressible chamber is in fluid connection with the inside of the tyre.
