20110125852, May 26, 2011

Filed:

Nov 25, 2009

Appl. No.:

12/625906

Inventors:

Larry L. Wolfe - Arvada CO, US

Assignee:

INTERNATIONAL BUSINESS MACHINES CORPORATION - Armonk NY

International Classification:

G06F 15/16
G06F 3/00

US Classification:

709206, 715758

Abstract:

A method and apparatus for processing messages. In one illustrative embodiment, a processor unit determines whether a predetermined number of keywords or a predetermined number of combinations of keywords associated with a recipient of a message is present in the message in response to receiving the message. In response to a determination that the number of keywords is present in the message, the processor unit generates an alert for the recipient.

Appl. No.:

6/345492

Inventors:

International Business Machines Corporation - Armonk NY

International Classification:

H04N 124
H04N 130

US Classification:

358293

Abstract:

An acousto-optic deflector may selectively deflect an applied light beam. The remaining undeflected zero-order beam varies considerably in power depending upon whether the beam is deflected. The zero-order beam is modulated and directed at a detection arrangement to detect a characteristic of the beam other than the selective deflection power variation. The modulation and detection is best employed to detect position feedback for an informational writing beam. An exemplary detection arrangement having a defined ringing frequency with a long shift time constant detects an amplitude modulation of the beam having a significantly higher frequency than that of the selective deflection power variation. The feedback may be in the form of an oscillation representing the position of the deflected beam as it is swept in a raster format and the detection arrangement detects the amplitude oscillations as indicative of the feedback.

International Classification:

G03G 1504
B41B 2108
B41B 1300
G02B 2730

US Classification:

355 3R

Abstract:

An optical system for use with laser chips to counteract variations in wavelength produced by semiconductor chips, to counteract astigmatism effects common to laser chips, to counteract variations in the distance between the plane of emission of the beam and the plane of a collimating lens, to counteract variations in beam size in perpendicular planes, to counteract variations in the divergence angle of emission common to laser chips, and to counteract tilt variations caused by imperfect reflecting surfaces. The system includes an apertured achromatic doublet lens for collimating the beam, a cylindrical lens, a rotating mirror, and a combination of toroidal and spherical lens.

International Classification:

US Classification:

355 14R

Abstract:

In an electrophotographic printer or the like, compensation is provided for environmental effects (temperature, humidity, photoconductor aging, etc. ) which would otherwise affect print quality. Analyzing print data allows identification of compensation locations; those are locations at which compensation is most critical, such as single pel lines. A series of clock pulses of varying phase displacement are employed, and selected based on environmental variations, so as to modify the print data at the identified compensation locations. The print data comprises a series of pulses. Compensation to control the width of lines perpendicular to the scan direction is effected by selectively advancing the leading edge of pulses defining a white/black transition and delaying the trailing edge of pulses defining the black/white transition. This control then affects the duration of the print pulses. For lines which are parallel to the scan direction width control is effected by adding gray pulses, both the leading and trailing edges of these gray pulses are controlled in accordance with environmental variations.
