A tyre for a motor car includes a tread and two shoulders. The tread includes at least one circumferential row of blocks disposed between first and second circumferential grooves. Each of the blocks is delimited by a section of the first circumferential groove and by first and second transverse grooves that extend from the first circumferential groove and converge at a common vertex spaced from the second circumferential groove. The common vertex is separated from the second circumferential groove by a continuous circumferential tread rib. A second transverse groove that delimits a first block is separated from a first transverse groove that delimits a circumferentially adjacent block by a solid tread portion. The solid tread portion extends from the first circumferential groove to the circumferential tread rib and forms a single body with the circumferential tread rib, spacing the first block and the circumferentially adjacent block from each other.

A cable containing an optical fiber is used to transmit data between an underwater remotely operated vehicle (ROV) and a support vessel floating on the surface of the water. The ROV pulls the cable through the water and as the ROV dives away from the support vessel, the optical fiber is released from the support vessel. Excess tension in the cable can damage the optical fiber and the tension can be highest close to the ROV. To prevent potential damage to the optical fiber, the ROV can store a portion of the cable and release the cable if the detected tension approaches the maximum working load. When the tension drops to a lower safe level, the release mechanism can stop releasing the cable.

To prevent foreign particles from adhering to an external surface of an electronic device and adversely affecting a user's enjoyment of the device, and to remove adhered foreign particles, a source of mechanical waves can be incorporated within the device. The source can provide mechanical waves tuned to prevent foreign particles from adhering, or to remove foreign particles adhered to the external surface of the device, for example by increasing the contact angle between the foreign particles and the outer component. In some cases, the electronic device can dynamically tune, modify, or adjust emitted waves to direct foreign particles towards particular regions of the device, or to provide waves better adapted at removing different types of particles. In some embodiments, the electronic device can include a reservoir for receiving and holding foreign particles until they are removed from the device.

A wakesurfing boat and a hull for a wakesurfing boat. The hull includes a bottom having a preselected length extending from a bow to a stern. The bottom includes a central ridge and port and starboard ridges extending below respective port and starboard bulwarks to define a substantially M-shaped bottom with concave portions to port and starboard of the central ridge. Port and starboard sponsoons extend below the port and starboard bulwarks proximate the stern. A trim wedge projects below the stern. Two rounded stern portions are provided proximate the stern. In a dynamic surfing mode, with selectively-fillable ballast tanks partially or fully flooded, water flowing through the port and starboard concave portions, combined with the ballast, increases resistance to the hull, resulting in a larger wake wave. Water passing around the structural features proximate the stern is directed toward a convergent zone in the wake, resulting in an improved wake wave shape.
