Patent CA-2331608-A1 (CA)
Title: Thermoacoustic tissue scanner
Inventor: KRUGER ROBERT A
IPC: A61B5/00
Filed: 1999-05-12
Abstract: Methods and apparatus for measuring and characterizing the localized electromagnetic wave absorption properties of biologic tissues (24) in vivo, using incident electromagnetic waves (26) to produce resultant acoustic waves (28). The tissue is exposed to modulating electromagnetic radiation, to produce modulating acoustic signals. The modulating acoustic signals are detected by an acoustic sensor (30) which is primarily sensitive to acoustic radiation at a focal point (27) distant from said sensor. Multiple measurements from multiple different focal points can then be combined into an image, or measurements at the same focal point at different excitation frequencies can be combined to produce an absorptivity spectrum for the tissue, either of which may be used for medical diagnostic purposes.

Abstract: A system (10) is provided for performing first-order authentication of articles marked with indicia (30) discernible in visible, ultraviolet, or infrared light or tagged with UV- or IR-sensitive chemicals. The first-order  authentication system provides reliable visual authentication by providing f or juxtaposition of the article-under-test (20) with a known reference-standard  sample-specimen (90, 100, or 300), while the article-under-test (20) is illuminated by a suitable source (65 or 250) of radiation in the visible, ultraviolet, or infrared portions of the electromagnetic spectrum. Thus, the  system (10) facilitates comparison to differentiate a genuine article from a  counterfeit article with first-order accuracy but at a substantially lower cost than that of automated authentication systems. Additionally, the system  can be used in both portable and desk top embodiments. The system preferably  has optional interchangeable holders (140 or 400) for various articles-under - test as well as an optional interchangeable holder (115) for various referen ce- standard sample-specimens.

Patent CA-2348718-A1 (CA)
Inventor: BATTHISH IBRAHIM
IPC: G06F9/45
Filed: 2001-05-25
Abstract: A compiler  comprises a lexical scanner with a dynamic character identification table that accommodates different standards for encoding characters in source and target characters. The scanner is associated with data files that enable conversion of the character identification table and also source code to conform to different standard character set representations. The scanner compares the character sets associated with the source and target codes. The source code is loaded into a buffer, and if a discrepancy in character sets exists, the buffered source code is converted to the target character set. The scanner also compares the character sets associated with the target code and the character identification table. If a mismatch exists, the scanner converts the character identification table to conform to the target character set. The lexical scanner provides greater flexibility in reading and generating program code.

Title: Quick release sacrificial shield and window assembly
Inventor: FARRAR JERRY L
IPC: B60J1/16
Filed: 1999-11-04
Abstract: A window assembly (10) for use in mass transit vehicles which allows the quick and easy removal and replacement of transparent, sacrificial glazing panels (16) of the window from vandalism and wear. The frame (12) of the window assembly incorporates one or more retainers (31) which fit into slots (30) along the interior sides of the window frame and sandwich the glazing between the frame and the retainers. In turn, the retainers (32) are essentially "locked" into position in the frame by an inner protective panel (16), which significantly inhibits the removal of the retainers from the window assembly when the protective panel is in its desired position against the window panel (14). Once the inner protective panel (16) is removed from the window assembly, however, the retainers and glazing can quickly and easily be removed from the frame, allowing the glazing and any remaining protective panels to be quickly and easily removed from the frame.
