And third, an axial hole (100) formed in the electronics carrier (106) and the rigid end-fittings (102) defining the curved space (104a) between the axial hole (100), the access means (107) and the rigid end-fittings (102).

An electromagnetic interference shielding apparatus for a signal transceiver employs two folded-edge mechanisms coupled together and an adhesive. The electromagnetic interference shielding apparatus includes a metal cover, a chassis having a waveguide output hole, and an adhesive. A first combination portion having a first curved section is disposed on an edge of the metal cover. A second combination portion having a second curved section corresponding to the first combination portion is disposed on an edge of the chassis. The adhesive is used to combine the first combination portion and the second combination portion. The waveguide output hole outputs a signal transmitted by the signal transceiver. The first combination portion and the second combination portion form a curved space that is used with the adhesive to prevent leakage of the transmitted signal and the interference of external noises.

Conformable spring-loaded earloops for over-the-ear style headsets are disclosed. The earloop for a headset generally comprises a prehensile member having a connecting member and a stabilizer portion and a ring integrally formed with and extending from the connecting member. The stabilizer portion is adapted to curve at least partially around and behind an ear to clip onto the ear in substantially a first plane. The ring is configured to removably receive and rotatably secure a receiver capsule of a headset therein and to direct the receiver capsule toward a concha of the ear. The prehensile member and the ring define an open-ended curved space to facilitate donning of the earloop. Upon application of an external force, the stabilizer portion is resiliently adjustable relative to the ring out of the first plane toward and away from the ear and / or in the first plane toward and away from the ring. The stabilizer portion returns to a static resting state configuration upon removal of external forces. The stabilizer portion has a larger cross-sectional dimension than the connecting member to facilitate the connecting member in functioning as a hinge for resiliently adjusting the stabilizer portion. The earloop further provides for adjusting the height between a center of the ring and the point along an interior surface of the stabilizer portion that rests upon the apex of the ear when worn. At least some of the inner portion of the stabilizer portion may be an elastomeric material.

A rotor and cage assembly includes a skeleton of curved spaced-apart side members affixed to laterally extending upper and lower spaced-apart members therebetween and surrounding the rotor. One of the curved spaced-apartside members is terminated with curved fingers. Three concave inserts insert laterally into the skeleton spanning 270° around the rotor. One of the concave inserts carries straight fingers that interlace between the skeleton side member curved fingers. A control assembly of plates having arcuate slots placed at 3 of the pivots of the skeleton assembly, control bars connected to the skeleton pivots, and an actuator connect to the control bars at one end effect arcuate rotation of the control bars resulting in the synchronized rotation of the arcuate slotted plates so that the interlaced straight fingers move closer together or farther apart with the fixed skeleton assembly curved fingers for different types of grain.

A buckling up phalanges joints type button input device and method use features that the phalanges joints can bend. A curved surface button input panel is installed inside sheathing. A curved surface mobile panel is installed corresponding to a curved surface of the button input panel, so as to form a curved space between the button input panel and the mobile panel. Fingers can stretch inside the curved space to operate buttons following an angle of the curved space. When either the curved surface mobile panel or the button input panel move, the curved space will become narrowed or extended. Once the curved space become narrowed, the phalanges joints will be locked on a turning point of the curved space due to a length of the fingers, so that the fingers cannot draw out. Thereby the phalanges joints will be locked if error data is inputted.

The invention relates to a modeling method and application thereof for the temporal and spatial evolution of vehicle behavior under path constraints. The modeling method includes the steps of: 1) acquiring a vehicle running route, and abstracting the running route into a space curve; 2) utilizing The geometric invariant parameters of the space curve, that is, the arc length, curvature and torsion at each point on the space curve, establish the Serret-frenet active frame of the vehicle moving along the space curve; 3) determine the relationship between each point on the space curve and the vehicle running The corresponding relationship of time changes in the process, combined with the Serret-frenet active frame at each point, calculates the velocity and acceleration of the vehicle at each point, and establishes a mathematical model of the space-time evolution of vehicle behavior under path constraints. Compared with the prior art, the running route of the vehicle in the present invention is abstractly drawn as a space curve instead of a plane curve. Compared with the existing way of abstracting the running route as a straight line or a two-dimensional curve, it has a wider applicability.
