Abstract: A system and method is disclosed for dynamically loading platform independent drivers. The
invention encompasses a "Printlet" and a "Printlet Dock Print Driver." collectively referred to as the
Printlet System. A Printlet is that portion of the present invention comprising platform-independent
software technology (such as Java) and, generally, is software which enables a computer system or a
network of electronically connected computers to communicate with a specific device (in the same
manner as a device driver). The Printlet is dynamically loaded from the connected device by the
operating system of a computer upon invocation by the user, or a client application,; or on demand.
The platform independent Printlet interfaces with a Printlet Dock Device Driver. A Printlet Dock Print
Driver (PDPD) is built into, or installed upon, the OS; is computer system platform and device
independent and implements, or otherwise activates, a defined PrintletManager's API and it preferably
provides a graphical user interface (GUI) to enable the user to select a Printlet-Enabled device. The
PDPD loads the Printlet from the Printlet Enabled device and, subsequently, activates the Printlet
software to thereafter place the computer system in communication with that device. Various
embodiments include, but are not limited to the addition of: a Download Manager which implements
various download protocols and manages a local cached; a multiplicity of GUI's to provide the user
with the capability to manage a plurality of devices, job ticket controls, display device status, and
administrative support; ability to detect Printlet-Enabled devices and add them to a device list; and the
ability to add device specific rendering and PDL generation, if desired.

Abstract: There is disclosed an energy filter for use in an electron
microscope, the energy filter having an electron passage that can
be evacuated more reliably than heretofore. The filter can be
designed compactly without increasing the polepiece gaps or the
spaces to accommodate coils. The energy filter has an
electron-deflecting magnet assembly. This assembly comprises a
pair of opposite polepiece bases, a pair of spacers interposed
between the polepiece bases, and a yoke mounted to side surfaces
of the polepiece bases. Magnetic polepieces and coil grooves of
a given width are formed in the opposite surfaces of the polepiece
bases. Bulges forming shunts are formed outside the coil grooves
in the polepiece bases. O-ring grooves are formed in the spacers
on the sides of the polepiece bases around the coil grooves.
Electron passage grooves are formed in the opposite surfaces of
the spacers to form the electron passage.
