Title: High spatial resolution area array detection readhead and method for using the same
Inventor: DOSMANN ANDREW J
IPC: G01N21/27
Filed: 1995-04-10
Abstract: The high spatial resolution area array detection readhead and method for using the same involve modifying an existing area array detection readhead to provide improved spatial resolution within the sample detection area. One modification involves reducing the field of view of the area array detection readhead. The reduction in the field of view increases pixel spatial resolution because the same number of pixels in the area array detector cover a smaller area. This reduction can be achieved by changing the magnification  of the lens of the area array detection readhead  or by moving the sample detection area closer to the area array detection readhead.  The next modification involves properly aligning the reduced field of view within the sample detection area to take advantage of the improved pixel resolution. Preferably, by rotating the typical area array detection readhead  90 degrees with respect to the sample detection  area, the length of the reduced field of view aligns with the width of the sample detection area. Finally, an optical wedge is positioned between the area array detection readhead and the sample detection area. The optical wedge is designed to shift the reduced field of view a predetermined number, X, of degrees from normal along the length of the sample detection area to cover a first field of the sample detection area. By inverting the optical wedge or introducing another optical wedge, the field of view is shifted -X degrees from normal and fills the remaining field of the sample detection area. As such, the sample detection area is divided into two fields that cover the entire sample detection area. Accordingly, by switching the optical wedge between the two wedge positions, the improved area array detection readhead shifts the reduced field of view + and - X degrees to image the entire sample detection area at the higher spatial resolution.

Patent CA-2150589-A1 (CA)
Title: Speed Sensor Filter
Inventor: AMSALLEN MARCEL
IPC: G01P15/16
Filed: 1995-05-31
Abstract: A  filter  for  removing  oscillations  and transients  from vehicle driveline component angular velocity measurement signals.  The filter determines, from successive measurements of angular velocity, any angular  acceleration  of  a  driveline  component. Predetermined sets of unity and fractional multipliers are   assigned  to  respective  ranges   of   angular acceleration.  Each succeeding measurement of angular velocity  is  estimated  by  adding  the  product  of  a selected modifier value and the difference between the currently sensed and the previously estimated values of angular velocity to the previously estimated value of angular velocity.  Multipliers are valued and selected so  that,  when  angular  accelerations  are  detected, relatively large percentages of the differences between currently sensed and previously estimated values of angular velocity are added a relatively small number of times to previously estimated values of angular velocity when the differences are relatively small.  Conversely, relatively small percentages of the differences between currently sensed and previously estimated values of angular velocity are added a relatively large number of times to previously estimated values of angular velocity when the differences are relatively large.

Patent CA-2153835-A1 (CA)
Title: Ion emitter and filter enhancing system
Inventor: CRONA STAFFAN C
IPC: B03C3/155
Filed: 1995-07-13
Abstract: An ion emitter and filter enhancing system used in conjunction with the existing filter of a conventional forced air system or used alone in the existing ambient air flow in a room. The ion emitters of the present system are in the form of flexible conductive brushes which float in the air flow increasing the output of ions as the conductive brushes move in the air flow. Particles charged by the ion emitters are attracted to each other and to any surface so that they readily adhere to a filter of a forced air system making the filter more efficient without upgrading the existing filter. The ion emitters are placed upstream of the filter to enhance filtering and downstream to remove molds or bacteria that can form in the ventilation system. Some of the charged particles will be attracted to the flexible conductive brushes, but since the brushes float in the air flow, the charged particles will be shaken off leaving the ion emitter relatively free of particulate matter so that the conductive brushes can emit uninterrupted air cleaning ions into the air flow and the time interval between which the ion emitters should be removed and cleaned is increased. The ion emitters are removably attached to a common power supply line. A method of removing particulate matter from air flow is also described.

Title: Evaporation control adaptor sleeve for vaporizer electrode
Inventor: REGEHR MARTIN W
IPC: F24F6/18
Filed: 1995-08-03
Abstract: A simple and inexpensive adaptor is provided for a commonly used household vaporizer to reduce and control its rate of vaporization. A thin insulating sleeve or tube is placed around one or more of the electrodes to lengthen  the path of the current so as to reduce its strength, and thus the rate of vaporization, whenever the hardness of  the water supply is too high.  By selecting the proper length of tube, or a tube with the proper size of  perforations, the current strength is easily adapted by the user to the water hardness to produce the desired rate  of evaporation.

Title: Flexible diaphragm tonometer and method of use
Inventor: BUTTERFIELD ROBERT D
IPC: A61B5/022
Filed: 1994-09-22
Abstract: A pressure waveform monitor (10) for non-invasively monitoring the pressure waveform inside a vessel, such as an artery, includes a flexible diaphragm (33) extended across an opening of a containing (29) containing a fluid (23). The flexible diaphragm (33) is placed against tissue surrounding an artery such that arterial pressure causes a deflection in the diaphragm (33). A deflection in the diaphragm (33) causes the fluid (23) to be redistributed throughout the container (29) which is effectively divided into an array of volume compartments. The relative volume distribution is determined through impedance plethysmography. The diaphragm (33) is maintained in a calibrated position by maintaining the array of volume compartments at relatively unchanged volumes. When the relative volumes remain essentially unchanged, calibrated tonometry is possible. The pressure within the container (29) is then used to determine the pulse waveform and the pressure within the artery.
