Patent CA-2319229-C (CA)
Inventor: MILLARD JOHN
IPC: G06F21/64
Filed: 1999-01-21
Granted: 2005-12-13
Abstract: System and method for verifying the integrity of contents within a computer file (5). A security value S is stored within the file (5). A verification function f is applied against the entire contents of the file (5) including S, where f is a function of S. Results R of the applying step are compared against a preselected value r, where r is not stored within the file (5). When R equals r, a determination is made that the file (5) has not been modified. f is typically a distributive invertible function such as the Cyclic Redundancy Check (CRC) function known as modulo p, where p is a prime number and is one bit greater than the length of S. Typically, the value of r is zero. Before executing the verification function f, a check generating program is first executed. This check generating program is executed by a computer (4) that is remote from the file (5), further enhancing the security of the system.

Title: Protocol for replicated servers
Inventor: HOLMBERG PER ANDERS
IPC: H04L69/40
Filed: 1999-09-23
Granted: 2008-04-01
Abstract: A fault-tolerant client-server system has a primary server, a backup server; and a client. The client sends a request to the primary server, which receives and processes the request, including sending the response to the client, independent of any backup processing. The response includes the primary server state information. The primary server also performs backup processing that includes periodically sending the primary server state information to the backup server. The client receives the response from the primary server, and sends the primary server state information to the backup server. The primary server state information includes all request-reply pairs that the primary server has handled since a most recent transmission of primary server state information from the primary server to the backup server. The primary server's means for performing backup processing may be activated periodically based on a predetermined time interval. Alternatively, it may be activated when the primary server's memory for storing the primary server state information is filled to a predetermined amount.

Title: Method and device for treating, especially cleaning, abrasive clearing or stripping of coatings, graffiti or other superficial soiling on parts, work pieces or surfaces
Inventor: PIEPER GERARD
IPC: B24C9/00
Filed: 1998-10-19
Granted: 2005-01-11
Abstract: The invention relates to a method and device for treating, especially cleaning, abrasive clearing or removing of coatings (1), graffiti or other superficial soiling on parts, work pieces or surfaces (3). A blasting means (2) is gravity fed from a holding container (11) to a carrying air stream (5) which is transported inside a hose guiding system constructed with outgoing and incoming lines. The blasting means are fed through said carrying air flow by low pressure, and, in a blasting chamber (25), are blasted against the surface (3) which is to be treated through a blasting lance (22). From the blasting chamber, said blasting means are transported back to the carrying air stream (5) in such a way that the blasting means (2) are circulated. The acceleration of the blasting means is essentially generated by the low pressure applied on the blasting chamber (25) and by increasing the blasting velocity in an acceleration section (L) by reducing the diameter of the outgoing line in the acceleration section (L). The low pressure outgoing line (20) is connected to a linear acceleration tube (21) which forms an acceleration section (L).  The acceleration tube which comprises a diameter reduction compared to that of the outgoing line is arranged before said blasting lance (22).

Title: Method for oxidation of volatile organic compounds contained in gaseous effluents and device thereof
Inventor: SALAMA AMIR
IPC: C25B3/23
Filed: 2001-07-17
Granted: 2009-03-17
Abstract: The present invention relates to both a method and a device for removing Volatile Organic Compounds (VOC) from gaseous streams in conduits, chimneys and/or exhaust ducts. The method is especially useful in eliminating a large variety of pollutants, and especially organic odorous pollutants such as mercaptans and sulfurous compounds. The method is based on the principle of direct oxidation of the pollutants by ozone and the conversion of these pollutants into non-harmful products, and comprises the steps of: a) providing an electrical corona discharge reactor capable of producing ozone; b) supplying an electric current to the corona discharge reactor; and c) causing the gaseous effluents to flow through the reactor. With this method, the volatile organic compounds contained in the gaseous effluents are oxidised by the ozone produced by the corona discharge reactor. The present invention also relates to a device for reducing this method into practice, this device being a corona discharge reactor comprising two concentric electrodes producing ozone.

Granted: 2010-07-20
Abstract: The present invention provides a method and an apparatus for the in vivo, non-invasive, early detection of alterations and mapping of the grade of these alterations, caused in the biochemical and/or in the functional characteristics of epithelial tissues during the development of tissue atypias, dysplasias, neoplasias and cancers. The method is based, at least in part, on the simultaneous measurement of the spatial, temporal and spectral alterations in the characteristics of the light that is re-emitted from the tissue under examination, as a result of a combined tissue excitation with light and special chemical agents. The topical or systematic administration of these agents result in an evanescent contrast enhancement between normal and abnormal areas of tissue. The apparatus enables the capturing of temporally successive imaging in one or more spectral bands simultaneously. Based on the measured data, the characteristic curves that express the agent-tissue interaction kinetics, as well as numerical parameters derived from these data, are determined in any spatial point of the examined area. Mapping and characterization of the lesion, are based on these parameters.
