Patent CA-2350980-A1 (CA)
Inventor: PILGRIM JEFFREY S
IPC: G01N21/39
Filed: 1999-11-12
Abstract: A method and apparatus (10) for detecting the presence of a specific concentration of gaseous species within a calibrated range in a gas sample a re disclosed. The ILS gas detection system (10) of the present invention simply  comprises an ILS laser (12) and an optical detector (16). However, the spectral bandwidth of the ILS laser (12) is preferably entirely included within one of the absorption bands or regions assigned to the intracavity gaseous species being monitored. Thus, within the calibrated range, the presence of the gaseous species changes the temporal characteristics of the ILS laser (12). Consequently, only a temporal characteristic of the output o f the ILS laser (12) need be monitored in order to quantitatively determine th e concentration of the absorbing gaseous species when using the ILS method of the present invention.

Title: Antivirus accelerator for computer networks
Inventor: NACHENBERG CAREY
IPC: G06F21/00
Filed: 1999-11-05
Abstract: System and method for examining a file (1) associated with an originating computer (2) to determine whether a computer virus is present within the file (1). The file (1) contains at least one sector. The file (1) is scanned by an antivirus module (3) associated with the originating computer (2). At that time, an identification of each scanned sector, a hash value for each scanned sector, a date of a most recent update to the antivirus module (3), and a version number of the antivirus module (3) are stored into a critical sectors file (4). The hash values can be calculated by an antivirus accelerator module (5). An authentication module (12) affixes a digital signature to the critical sectors file (4). The file (1), the critical sectors file (4), and the digital signature (15) are then transmitted over a computer network (14) to a recipient computer (11). An antivirus module (3'), an accelerator module (5'), and an authentication module (12'), respectively identical to corresponding modules (3, 5, 12) of' the originating computer (2), are associated with the recipient computer (11). All of the file (1) sectors that were scanned by the originating computer (2) are examined by said second antivirus module (3'). Each of these sectors again has its hash value calculated and compared with the hash value of the corresponding sector as stored within the critical sectors file (4). When any calculated hash value fails to match a corresponding stored hash value for any sector, the second antivirus module (3') is commanded to rescan the entire file (1). Additionally, the recipient computer (11) decrypts the digital signature (15) produced by the originating computer (2) to verify the authenticity of the contents of the critical sectors file (4).
