Patent CA-2191104-A1 (CA)
Title: Lag1: a gene for increasing the longevity of eukaryotes
Inventor: JAZWINSKI S MICHAL
IPC: A61K38/00
Filed: 1995-06-02
Abstract: The present invention provides a unique eukaryotic gene, called LAG1, which controls the longevity of eukaryotic cells.  According to the present invention, over expression of LAG1 in older cells has a rejuvenating effect which not only increases cellular life span but also reproductive capacity and cellular tolerance to stress factors such as starvation and low pH.  Moreover, the present invention identifies two domains in LAG1 one having a life span limiting function and the other a life span extending function.  Hence, according to the present invention, the longevity and tolerance to stress of cells is increased when provided with the wild type polypeptide or mutant LAG1 polypeptides which, for example, lack the "life span limiting domain".

Abstract: An injection tube for extruding and gassing of foundry sand in cavities in a core box has a first passage for passing sand and a second passage for passing hardening fluid. Sand may be injected simultaneously to the introduction of hardening fluid into the cavities. Alternatively, sand may be injected prior to introduction of hardening fluid into the cavities. A method includes the step of providing an injection tube having a first passage for passing sand and a second passage for passing hardening fluid. The method further includes the steps of injecting sand into the cavities, adjusting the height of the tube in the core box, and introducing the hardening fluid into the cavities. In an alternative method, the hardening fluid is introduced simultaneously to the injection of sand.
Patent CA-2195807-A1 (CA)
Inventor: KIELLAND PETER JOHANN
IPC: G06F3/0354
Filed: 1997-01-23
Abstract: A hand-held computer input device is disclosed which accurately digitizes the coordinates of graphical features appearing on documents. The device is similar to a conventional computer "mouse" in that a trackball and a pair of X-Y motion encoders are used to digitize the approximate trajectory of the operator's hand motion into the computer. The present invention prevents geometric distortion of the document coordinates normally caused by variations in the mouse's yaw attitude with respect to the X-Y coordinate system of the document being digitized. Two additional components are added to the conventional mouse configuration; A removable sighting cursor is affixed to the side of the device and used by the operator to aim on the graphical features being digitized from the document. A second trackball assembly is also added to the mouse's lower surface at a known distance from both the first trackball assembly and the sighting cursor thereby enabling yaw variations to be measured and compensated for. Instantaneous differences between the motion detected at each of the trackball locations are used to compute the subtended changes in the device's yaw attitude. A tracking and correction algorithm then computes geometrically rectified document coordinates for the sighting cursor as it is moved about over the document.

Title: Methods and compositions for inducing mucosal immune responses
Inventor: MITCHELL WILLIAM M
IPC: A61K9/00
Filed: 1995-07-03
Abstract: The invention provides a method of inducing a mucosal immune response in a subject, comprising administering to the mucosa of the subject an amount of antigen-encoding DNA effective to induce a mucosal immune response complexed to a transfection-facilitating lipospermine or a lipospermidine. In the method of inducing a mucosal immune response, the antigen-encoding DNA can encode an antigen that is expressed on the surface of infected cells during the course of infection. DNA encoding the envelope glycoproteins of viral pathogens is used in the present method. Lipospermines and lipospermidines are bifunctional molecules consisting of one or more hydrophobic chains covalently linked to a cationic grouping in which there is coordination of three or more amide hydrogens with a phosphate oxygen of the DNA chain forming an ionic charge complex. One preferred example of a lipospermine is DOGS (droctadecylamidoglycylspermine). The invention also provides a composition, comprising an amount of DNA encoding an envelope antigen or envelopeassociated antigen of a pathogen complexed to a lipospermine. More specifically, the invention provides a composition, comprising an amount of DNA encoding an envelope antigen of HIV complexed to a lipospermine.

Title: Key generation from a given string for entity authentication
Inventor: KOU WEIDONG
IPC: H04L9/06
Filed: 1997-07-17
Abstract: The invention provides a scheme for generating a symmetric encryption key for a given character string, such as a password or an alphanumeric. There is no limitation on the length or content of the given character string. The character string is converted to a bitstream using a standard character encoding scheme, such as ASCII. The bitstream is then subjected to combinations of bitstream processing operations over multiple rounds. The bitstream processing operations can include splitting the bitstream into multiple sub-bitstreams, reordering and shuffling the sub-bitstreams, performing logical bit-wise operations on the sub-bitstreams, performing one-way hashing on the sub-bitstreams, and combining the multiple sub-bitstreams back into a single bitstream through logical bit-wise operations on the sub-bitstreams. Prior to converting the character string into a bitstream, the given character string may be optionally combined with an initialization character string (for example, an initialization string associated with a particular processor), and it is the combined character string that is then encoded and used for generating an encryption key. Applying the combination rounds of the bitstream processes multiple times, for example sixteen times, will result in a strong key for encryption.

Filed: 1996-01-22
Abstract: A digital communication system having a punctured convolutional coding system and method. The digital communication system includes a coder for coding a digital input to be transmitted from a transmitter and a decoder for decoding the coded input received at the receiver. The coder includes a convolutional coding circuit of rate k/n for outputting a convolutional coded output and a puncturing circuit for puncturing the convolutionally coded output to achieve a punctured code rate of z/q, where z = .gamma.k. The puncturing circuit punctures the convolutional coded output according to a deleting pattern chosen to have a bit length of L = p.gamma.n, where p ~ 2. The puncturing circuit outputs a punctured output at punctured code rate of z/q and the punctured output is transmitted to the receiver. The receiver decodes the transmitted punctured output and outputs a decoded output.

Title: Distributed photographic system for taking self portraits
Inventor: TEN BRINKE MACHIEL A
IPC: G03B15/00
Filed: 1996-01-24
Abstract: A distributed photographic system for taking self portraits is disclosed which reduces cost as compared to conventional photographic booths by separating image acquisition (10) and image rendering (30) functions. Control over the system is also increased by allowing a remote operator in a commercial setting to remotely govern the image acquisition system. In the preferred embodiment, the image acquisition system utilizes a beam splitter to allow image bearing light to pass through into a video camera which then projects images through a liquid crystal display and back onto the beam splitter which reflects outwardly to the user. The user then can choose which video image the user wishes to have placed onto a hard-copy medium by indicating through a user panel that an image is acceptable. Upon doing so, the image is sent electronically to a remote printing station which is controlled by an operator. The user then goes to that operator to collect and pay for the hard-copy medium, thereby eliminating a need for additional automatic fund collecting systems.
