Title: Method for determining steering position of automotive steering mechanism
Inventor: MADAU DINU PETRE
IPC: B60G17/016
Filed: 1997-03-27
Abstract: A method for determining a steering wheel angle of a vehicular steering system includes determining a center position for the steering sensor output every time the vehicle is started.  The method employs the use of a yaw sensor for computing an estimate of the actual steering position so that a center position may be back computed to provide immediate and accurate steering position data using the steering sensor signal for controlling an automotive device.  The accuracy of the initial estimates may be improved upon by implementing interim and final center algorithms as vehicle operating characteristics permit.
Patent CA-2204587-A1 (CA)
Inventor: KEILBACH KEVIN A
IPC: G01N21/65
Filed: 1997-05-06
Abstract: A photodetector is used to monitor contamination of optical elements within an optical system. The photodetector is aligned to detect nonspecular/diffuse reflections attributable to surface irregularities of particulate matter residing on the surfaces of the optical elements within the system. An increase in the intensity of the nonspecular reflections corresponds to increased levels of contamination on the surface of the optical element. An electronic detector circuit performs signal processing on the photodetector output signal and generates an output signal corresponding to the contamination level. In another aspect of the invention, the photodetector circuit is incorporated into a Raman gas analysis system. The invention also provides a method for detecting nonspecular reflection in an optical resonant system by generating and resonating an optical energy beam in an optical resonant cavity so as to irradiate an optical element within the cavity; detecting optical energy reflecting off the optical element; and generating an output signal functionally related to the intensity of the detected optical energy.

Title: Aperture-coupled planar inverted-f antenna
Inventor: PAPATHEODOROU STELIOS
IPC: H01Q9/04
Filed: 1998-01-15
Abstract: An aperture-coupled planar inverted-F antenna (PIFA) including a radiating patch formed on one side of a ground plane and separated therefrom by a first dielectric which may be air, foam or another suitable material. A shorting strip connects a side of the radiating patch to the ground plane at a point corresponding to a dominant mode null, such that the size of the radiating patch may be reduced by a factor of two. A microstrip feedline is arranged on an opposite side of the ground plane and separated therefrom by a second dielectric which may be part of a substrate formed of printed wiring board material. Signals are coupled between the microstrip feedline and the radiating patch via an aperture formed in the ground plane. The use of aperture coupling avoids the excessive cost associated with conventional TEM transmission line or coaxial feeds, while providing improved manufacturability and ease of integration relative to PIFAs with conventional feeds.  Moreover, the aperture coupling provides improved tuning flexibility. For example, a portion of the microstrip feedline may be used as a tuning stub to provide impedance matching on the feedline.

Patent CA-2232043-A1 (CA)
Title: Nitrosated hemoglobins and therapeutic uses therefor
Inventor: STAMLER JONATHAN S
IPC: A61K35/18
Filed: 1996-09-13
Abstract: S-nitrosothiols (RSNOs) can donate the NO group to the .beta.93 cysteine residues of hemoglobin (Hb) without inactivating the heme. S-nitrosylation of Hb is under the allosteric control of oxygen and the oxidation state of heme. NO group release from S-nitrosohemoglobin (SNO-Hb) is further facilitated by intracellular low molecular weight thiols, forming RSNOs which can be exported from the erythrocyte to regulate blood pressure and platelet activation. SNOHb can be formed by reaction of Hb with S-nitrosothiol. This procedure avoids oxidation of the heme. Other methods can be used which are not specific only for thiol groups, but which nitrosate Hb more extensively, and may produce polynitrosated metHb as a product or intermediate product of the method. SNOHb in its various forms and combinations thereof (oxy, deoxy, met; specifically S-nitrosylated, or nitrosated or nitrated to various extents) can be administered to an animal or human where it is desired to oxygenate, to scavenge free radicals, or to release NO+ groups to tissues. Thiols and/or NO donating agents can also be administered to enhance the transfer of NO+ groups. Examples of conditions to be treated by SNO-Hbs or other nitrosated or nitrated forms of Hb include ischemic injury, hypertension, angina, reperfusion injury and inflammation, and disorders characterized by thrombosis.
