Abstract A catheter placement device (see FIG. 2) includes a needle unit, which in an initial position is releasably engaged with a housing distal end and has a sharp needle passing through a catheter and protruding distally of it. There is also a telescopic protector including guard unit, which is sliding in a housing guide. After inserting the needle into patient's vein, operator one-handedly pushes the guard unit distally, thereby emplacing the catheter, displacing the protector into a full length position and locking therein, and passively disengaging the needle unit from the hosing by a trigger cam located on the guard unit. As a result, a retracting spring moves a needle into retracted position, wherein it is protected from any contact with personal. Then, operator disconnects the guard from the catheter, turns the housing and occludes the catheter entrance with a cap, which was detachably mounted on the housing.

Shaped glasses have curved surface lenses and spectrally complementary filters disposed on the curved surface lenses configured to compensate for wavelength shifts occurring due to viewing angles and other sources. The spectrally complementary filters include guard bands to prevent crosstalk between spectrally complementary portions of a 3D image viewed through the shaped glasses. In one embodiment, the spectrally complementary filters are disposed on the curved lenses with increasing layer thickness towards edges of the lenses. The projected complementary images may also be pre-shifted to compensate for subsequent wavelength shifts occurring while viewing the images.

The image sensor includes the deep guard ring and a deep P well surrounding the noise blocking area, thereby preventing crosstalk between adjacent pixels. In addition, an ion implantation layer is divided by the noise blocking area, so that substrate crosstalk is effectively eliminated.

A scanning probe microscope prober employs a self-sensing cantilever including a first wire through which a current is supplied to a probe, and a second wire used in a sensor circuit for detecting a deformation of the cantilever. The prober includes guard potential generation means for causing the second wire to be employed as a guard wire for the first wire, and second wire switching means for switching over the second wire to be used in a time division manner in one of a first period during which the second wire is used as a sensor, and a second period during which the second wire is held at a guard potential. The probe is moved, after obtaining a two-dimensional distribution in the first period, to a predetermined position on the basis of the two-dimensional distribution in the second period for measuring a current or voltage of the first wire.
