Abstract: An audio assembly provides audio content to a user. The audio assembly comprises an elongated body, a negative vent assembly, and a positive vent assembly. The elongated body includes an audio waveguide. The negative vent assembly is coupled to the elongated body and includes at least one negative vent that vents negative acoustic pressure waves generated by a back surface of a transducer coupled to a first end of the audio waveguide. The positive vent assembly is part of the elongated body and is coupled to a second end of the audio waveguide. The positive vent assembly includes at least one positive vent that vents positive acoustic pressure waves generated by a front surface of the transducer.

Abstract: The invention relates to a device for protecting at least one active component of an electronic module, able to receive a microwave electromagnetic signal as input and to provide a microwave electromagnetic signal to said at least one active component. This device includes a delay module able to apply a predetermined delay time to the microwave electromagnetic input signal, connected in parallel with a switch-triggering device able to compare a power level of the microwave electromagnetic input signal to a power threshold and to command switching by a switch connected at the output of the delay module, an output of said switch providing the microwave electromagnetic signal to said at least one active component, the predetermined delay time being such that the switching is done before the arrival of the microwave electromagnetic output signal from the delay module.

Abstract: A rare earth (Ln) phosphate is described, wherein Ln is either: (1) at least one rare earth selected from cerium and terbium, or (2) lanthanum in combination with at least one of the two above-mentioned rare earths, and wherein the phosphate has a crystalline structure of the monazite type with a potassium content of at most 6000 ppm. The phosphate can be obtained by the precipitation of a rare earth chloride at a constant pH lower than 2, by calcination at a temperature of at least 700° C. and by redispersion in hot water. A phosphor obtained by calcination of said phosphate at at least 1000° C. is also described.

A phosphor obtained by the calcination of the phosphate at at least 1000° C. is also described.

Abstract: An optical surface-finishing tool includes a rigid support (4) having a transverse end surface (13); an elastically-compressible interface (5) which is applied against the end surface (13) such as to cover same; and a flexible buffer (6) which can be applied against the optical surface (2), which is applied against the interface (5) and which covers the interface at least partially, opposite and in line with the end surface (13). The buffer includes a central part (6a) which is in line with the end surface (13) and a peripheral part (14) which extends transversely beyond the end surface (13). There is also an elastic return element (15) having a collar (18) which is used to connect the peripheral part (14) to the support (4). Moreover, the collar (18) includes a continuous peripheral part (22) which rests on the peripheral part (14) of the buffer (6) such as to co-operate therewith.

Abstract: A tool for polishing an optical surface of a lens includes a rigid support including a support surface, a first layer called the buffer made from an elastic material and covering at least part of the support surface, and a second layer called the polisher and covering at least part of the buffer. The buffer has a first surface adhering to the support surface and a second surface opposite the first surface. The polisher has a first surface adhering to the second surface of the buffer and a second surface called the polishing surface opposite the first surface and adapted to polish the optical surface of the lens by rubbing against it. The polishing surface is a toric surface and, to be able to polish an atoric optical surface, the buffer is adapted to be compressed elastically and the polisher is adapted to be deformed to espouse the atoric surface. Applications include polishing atoric optical surfaces.

The process includes a step a) of machining the surface by removing material by moving a cutting tool along a continuous trajectory to form grooves, two adjacent grooves being spaced by a constant pitch from 0.01 mm to 3 mm, and a step b) of smoothing the machined surface by moving a smoothing tool along a continuous trajectory formed of passes, two adjacent passes being spaced by a constant pitch from 0.2 mm to 3 mm, to effect band-pass filtering of the undulations of the surface between a low frequency corresponding to a surface envelope and a high frequency corresponding to a background roughness.
