Patent CA-2301933-A1 (CA)
Title: Chair tilt lock mechanisms
Inventor: BEGGS KEN A
IPC: A47C1/027
Filed: 2000-03-22
Abstract: A chair seat tilt lock mechanism has a detent to latch an actuating lever in a locked and unlocked position. When the lever is moved to a locking position, a spring urges a moveable locking member toward a locking position, however, the moveable locking member only moves to its locking position when the chair is tilted to properly register the moveable locking member with a fixed locking member. When the lever is moved to an unlocking position, another spring urges the moveable locking member to an unlocking position. The moveable locking member may be a slider which slides under a fixed abutment to lock the chair from tilting. Alternatively, the moveable locking member may be a pivoting arm with a series of openings which may receive the forked end of a tongue in a locked position.
Patent CA-2304632-A1 (CA)
Title: System and method for authentication of goods
Inventor: FRASER JAY
IPC: B42D15/10
Filed: 1998-09-29
Abstract: An authentication system comprising a medium (2) having a plurality of elements (3), the elements being distinctive, detectable and disposed in an irregular pattern or having an intrinsic irregularity. Each element is characterized by a determinable attribute distinct from a two-dimensional coordinate representation (4) of simple optical absorption or simple optical reflection intensity. An attribute and position of the plurality of elements, with respect to a position reference, is detected. A processor generates an encrypted message (8-10) including at least a portion of the attribute and position of the plurality of elements. The encrypted message is recorded in physical association with the medium. The elements are preferably dichroic fibers, and the attribute is preferably a polarization or dichroic axis, which may vary over the length of a fiber. An authentication of the medium based on the encrypted message may be authenticated with a statistical tolerance, based on a vector mapping of the elements of the medium, without requiring a complete image of the medium and elements to be recorded.

Patent CA-2336330-A1 (CA)
Inventor: RITTLE LOREN J
IPC: H04B7/26
Filed: 1999-06-08
Abstract: A communication device employs a method and apparatus for transmitting and receiving information packets using multiple layers of error detection. A sending communication device constructs an information packet to include user information divided into multiple data blocks, a primary error detection code for each data block, and at least a portion of a secondary protection code. The secondary protection code provides error protection for the entire information packet. The secondary protection code is selected such that it can be incrementally determined by a receiving device as data blocks are received and accepted by the receiving device, regardless of order of reception of the data blocks. Since the secondary protection code is incrementally determined, processor utilization is better regulated and delays associated with sending acknowledgments are minimized.

Filed: 1999-08-10
Abstract: The present invention provides a method for presentation of multiple disease associated antigens in antigen-presenting cells which can be used to generate a prophylactic or therapeutic immune response against the disease with which the antigens are associated. The method employs differential screening of nucleic acid sequences expressed by target and non-target cells. By identifying nucleic acid sequences preferentially expressed in a target cell population and expressing the identified sequences in antigen-presenting cells, one can stimulate an immune response directed at a target cell population without being limited to single, previously identified antigens.
