The utility knife device generally comprises a sheath, covering a portion of the user's hand and a blade housing which attach together at a connection point. The blade housing is made up of a casing which preferably encloses the user's index finger, a blade housed within the casing and a trigger which extends out of the casing and manipulates the blade. The blade is capable of extending outward from the casing being held in place for use. The blade is also capable of automatically retracting within the casing so that the blade is not exposed.

An optical channel monitor is provided that sequentially or selectively filters an optical channel(s)of light from a (WDM) optical input signaland senses predetermined parameters of the each filtered optical signal (e.g., channel power, channel presence, signal-noise-ratio). The OCMis a free-space optical device that includes a collimator assembly, a diffraction gratingand a mirror. A launch pigtail emits into free space the input signal through the collimator assemblyand onto the diffraction grating, which separates spatially each of the optical channelsof the collimated light, and reflects the separated channels of light onto the mirror. A &#x3bb;/4 plateis disposed between the mirrorand the diffraction grating. The mirror reflects the separated light back through the &#x3bb;/4 plateto the diffraction grating, which reflects the channels of light back through the collimating lens. The lensfocuses each separated channel of light (&#x3bb;-&#x3bb;) at a different focal point in space. One of the optical channelsis focused onto a receive pigtail, which then propagates to a photodetector. A pivoting mechanismpivots the diffraction gratingor mirrorabout a pivot pointto sequentially or selectively focus each optical channelto the receive pigtail. A position sensordetects the displacement of the diffraction gratingor mirror.

Optical channel monitor

An optical spectrum analyzer (OSA)sequentially or selectively samples (or filters) a spectral band(s)of light from a broadband optical input signaland measures predetermined optical parameters of the optical signal (e.g., spectral profile) of the input light. The OSAis a free-space optical device that includes a collimator assembly, a diffraction gratingand a mirror. A launch pigtail emits into free space the input signal through the collimator assemblyand onto the diffraction grating, which separates or spreads spatially the collimated input light, and reflects the dispersed light onto the mirror. A &#x3bb;/4 plateis disposed between the mirrorand the diffraction grating. The mirror reflects the separated light back through the &#x3bb;/4 plateto the diffraction grating, which reflects the light back through the collimating lens. The lensfocuses spectral bands of light (&#x3bb;&#x2013;&#x3bb;) at different focal points in space. One of the spectral bandsis focused onto a receive pigtail, which then propagates to a photodetector. A pivoting mechanismpivots the diffraction gratingor mirrorabout a pivot pointto sequentially or selectively focus each spectral bandto the receive pigtail. A position sensordetects the displacement of the diffraction gratingor mirror.

Pawl controlled reel extension

Apparatus is provided for wrapping a line, the line having an average cross section dimension D, and includes a reel having an axis of rotation, a hub outer surface extending about said axis, and two axially spaced flange surfaces which face one another, outwardly of the reel surface, and across a groove defined between said flange surfaces and outwardly of the hub surface. The improvement includes:
