Patent CA-2277950-A1 (CA)
Title: Rheology-modified thermoplastic elastomer compositions and articles fabricated therefrom
Inventor: PARIKH DEEPAK RASIKLAL
IPC: C08L23/16
Filed: 1998-01-29
Abstract: Rheology-modified TPE compositions are prepared by peroxide modification of a melt blend of an EAO polymer or EAO polymer blend and a high melting polymer such as polypropylene or a propylene/a-olefin copolymer. The resulting compositions have an elastomeric phase, a non-elastomeric phase and certain physical properties that exceed those of a like composition that is not rheology-modified or of the same composition prior to rheology modification. The compositions can be used to make a variety of articles of manufacture, such as automotive parts, non-automotive parts, roofing membranes, and boot shafts, via conventional procedures.

IPC: A61M5/315
Filed: 1998-02-04
Abstract: Universal safety syringe having a protective cap, a cylinder, a plunger and a cannula mounted on a cannula base, it being the case that the cannula base is designed such that it can be pushed firmly against a stop in the protective cap, that the protective cap, which can be pushed externally onto a cone, corresponding to a Luer cone, of the cylinder, is provided with a narrowed section, which is provided on the inside of the cap, in front of a recess designed for receiving the cannula base, and delimits the push-on travel, that a recess which receives a cannula base is provided with an undercut which prevents the cannula base from being removed in the forward direction, and with an undercut of which the effect can be overcome by the cone being widened from the inside and which is provided for safeguarding the cannula stop from being pushed in unintentionally during insertion of the syringe, and it also being the case that the plunger is designed with a section which widens the cone cylindrically and with a mushroom-shaped plunger head, which comes into pulling contact with the needle stop.

Patent CA-2282016-A1 (CA)
Inventor: GIFFORD MAURICE MERRICK
IPC: G07C9/00
Filed: 1998-03-02
Abstract: Methods and apparatus for providing a security check are disclosed. Many conventional security checks require the recording or transmission of a user data sets associated with respective authorised users.  A problem arises with these systems if the user data set becomes known by unauthorised persons. In order to address this problem the present invention proposes the recording or transmission of only part of the user data set in insecure sections of the system. For example, a security check preventing unauthorised remote access to a shared computer (20) is provided by capturing a user data set representing a user's iris, operating the user's personal computer (10) to select only a portion of the captured data set requested by the shared computer (20) and transmitting the portion along a telecommunications line (16). The shared computer (20) derives partial data sets from stored user data sets using a similar selection to that used by personal computer (10) and compares the partial data set it has derived with the partial data set transmitted by the personal computer (10) in deciding whether to grant access. Point-of-sale devices and cards recording only partial user data sets are also disclosed.
Patent CA-2283598-A1 (CA)
Title: High-speed indoor wireless chirp spread spectrum data link
Inventor: PINKNEY JOHN A
IPC: H04B1/69
Filed: 1999-09-27
Abstract: This invention modulates data onto a radio channel in such a way that the deleterious effects of the channel are reduced. This is accomplished in three steps:  first, the information signal is modulated using a phase-differential modulation scheme. Second, the modulated signal is spread in both time and frequency by passing it through a dispersive filter, transmitting it through the channel, and removing the spreading using a dispersive filter in the receiver with the opposite characteristics of the filter in the transmitter. The third step, after demodulation, is to pass the signal through a low-pass filter to gather up the signal energy which has been dispersed by the channel. All three of these steps can be implemented with simple functional blocks, making this system very inexpensive to implement. Also included are two methods for enhancing the data throughput of the basic system, making it more bandwidth efficient.
