Brackets 4 are fastened on the U-shaped frame members with screws 21 to allow wall mounting.

A cover for decorating a motorcycle helmet, including a substantially circular exterior material portion, having variable decoration, connected anteriorly and at the sides to a substantially circular interior mesh material portion by a seam. The enclosure provides two openings on either side of the invention, providing spaces through which the helmet's chinstraps can be threaded through. The seam ends in the posterior of the enclosure to provide an opening in the back of the invention through which the helmet may be inserted. Both pieces of fabric provide corresponding non-permanent fastening agents which are used to secure the invention around the helmet inserted inside. Alternatively, the invention may be a cover for decorating a motorcycle helmet, including a substantially circular / helmet shaped silicon skin / elastic material portion, having an opening on either side of the enclosure through which the helmet's chinstraps can be threaded through, and a formed lip around the edge of the enclosure which wraps around the exterior of the helmet to fit on the interior, as to secure the invention to the helmet in a non-permanent fashion.

The invention relates to breathing apparatus, particularly of the open-circuit type, comprising a backpiece equipped with means, particularly involving straps, to allow it to be worn on the back of a wearer, the backpiece being intended to support at least one cylinder equipped with a valve, the backpiece being equipped with a coupling which, intended to collaborate with the valve, is connected to a regulator. The coupling comprises an air intake tube on which a bushing is mounted such that it can pivot and move in terms of axial translation. The bushing is mounted in a sleeve that forms an operating knob, is prevented from turning in the sleeve and is free in terms of translational movement with respect to the latter.

The invention provides an optical-scanning examination apparatus with a simple configuration, in which the resolution of acquired images can be freely changed and in which the fluorescence image intensity and examination depth can be adjusted to suit the purpose of examination. The optical-scanning examination apparatus includes a light source unit; a focusing lens for forming a first intermediate image of excitation light; an imaging lens; a first objective lens; an optical fiber bundle; a second objective lens; and an imaging unit for imaging return light that returns via the second objective lens, the optical fiber bundle, the first objective lens, and the imaging lens. In addition, a scanning mirror device, which is disposed at the first intermediate image position, is formed of a plurality of mirrors that simultaneously receive the first intermediate image and that can be selectively turned on and off.

An eyewear system enables a person to switch lenses among a variety of frames or switch a variety of lenses within a single frame. The lenses can be easily attached to and detached from a frame assembly that may or may not otherwise contain lenses. The lenses may be frameless or positioned in one or more subframe assemblies.

An acoustic absorbing device includes a housing having a chamber formed by an outer peripheral wall and a bottom wall, a hood engaged into the housing, an absorbing member engaged into the hood, and a silencer engaged into the absorbing member, the silencer and the absorbing member may be selectively attached to the hood or may be easily replaced with the other ones or new or different ones according to different environment. The silencer may include an outer cap extended into or out of the absorbing member. The housing includes one or more couplers for selectively coupling the housing to the other coupling or supporting members.

A display device that can be mounted to a surface, such as a window, using static attraction. The display device has an illumination assembly circuit including a light source (such as an LED), a power supply (such as a battery) and a switch interposed therebetween. The illumination assembly is either attached to or enclosed within a mounting film, such as a flexible polymer that is electrostatically attracted to a surface. A preferred device has indicia printed on it to display, and with which the LEDs cooperate.

A digital programmable driver for a solenoid valve comprises at least one valve driver circuit for opening and closing the valve and a controller capable of sending an output signal to the valve driver circuit. The valve driver circuit comprises a power switch for providing current to the valve in order to open the valve. The output signal sent by the controller directs the power switch of the valve driver circuit to provide current to the valve, thereby causing the valve to open. The controller receives a plurality of parameter values, and responsive to the plurality of parameter values, calculates a rise time, a pull-in duty cycle, a fall time, and a hold duty cycle so as to modify the output signal sent to the valve driver circuit. The plurality of parameter values comprises valve resistance, valve inductance, supply voltage, valve pull-in current, valve hold current, and valve pull-in time.

A tool for beveling the end of a pipe is comprised of a hollow, tubular body having a central, longitudinal axis of rotation, an inboard coupling end, and an opposite outboard working end. A plurality of longitudinally spaced, transversely directed latching pin bores of equal size are defined through the wall of the tubular body. A core member is disposed coaxially within the tubular body. The core member includes a beveling cutter head and a longitudinal stem having a radially inwardly directed, circumferential latch position groove. A transversely oriented latching pin is engaged in a selected one of the latching pin bores in the body and with the latch position groove of the core stem. This allows alternative selection of each of the latch position bores for insertion of the latching pin. The particular bore selected determines the longitudinal position of the core stem latch position groove within the body that will be aligned with the latching pin. This, in turn, determines the extent of protrusion of the core member cutter head from the outboard end of the tubular body, and thus the depth of the beveling cut in the pipe.
