Patent CA-1208781-A (CA)
Inventor: AHOLA RAIMO
IPC: G01H9/00
Filed: 1983-12-19
Granted: 1986-07-29
Abstract: Abstract of Disclosure The present invention concerns a procedure for analysing the reciprocating motion of a given object or its motion component transversal to the object's direction of travel, based on the passage time of electromagnetic radiation in the optical range and wherein by a light source, such as a laser or photodiode, a periodic light beam is directed on the object. The problem solutions known in the art are not suitable for flexible and accurate measurement and analysis of small motion amplitudes of reciprocatingly moving objects. In order to dispel these difficulties, the invention is mainly characterized in that the change of the passage times of light pulses that have travelled to the object and been reflected back therefrom, in relation to a given reference value, is transformed into an analog voltage proportional to the change.

Abstract: Case 2790 MONITOR FOR SCR SYSTEM             Abstract of the Disclosure A monitor for a system having a number of SCRs connected across an AC power source has several neon lamps connected across each SCR or each group of SCRs.  The SCRs are at a high voltage and the neon lamp display is in proximity to the SCRs.  The several neon lamps associated with one SCR or group of SCRs are formed in a cluster with the distance between clusters being greater than the distance between the lamps in a cluster.  A video camera, spaced from the SCRs and substantially at ground potential provides an image of clusters of neon lamps.  An image processor derives from the image, information on the location and light intensity of each cluster and this information is stored in a memory.  In one form of the invention a lens over each cluster blurs the image of the cluster to make each cluster appears as a larger single light source rather than several individual light sources.  If a cluster fails to light over a cycle of the AC power source, a decision processor provides an output indicating this.  The decision processor can be programmed to shut down the system when a critical combination of SCRS fail.  The condition of the lamps in each cluster is also monitored to determine lamp failure by comparing the light intensity from a cluster with a threshold that is stepped between a level representing no light and a level representing maximum light.  A sudden decrease in the level of light from a cluster indicates lamp failure and a warning signal is provided.

Abstract: ABSTRACT OF THE DISCLOSURE      A signal conditioner for use with cardiographic data and other biological signals includes a baseline shift circuit and a variable gain amplifier.  A feedback loop is provided for the output signal with a reference which designates the maximum value of the output signal.          Within the baseline shifting circuit,there is provided circuitry which compares the amount of offset of the negative excursions of the waveform from a reference lead so as to introduce a feedback compensation signal which shifts the baseline and thereby compensates for drift in the baseline.  Integration circuitry in the form of counters of clock pulses are provided in the control of both amplifier gain and baseline shift.  Timing circuitry provides for the interleaving of set-up intervals with data aquisition intervals, the gain adjustment and baseline adjustment being accomplished only during the set-up intervals.  Sensing of temporal data by waveform analysis is utilized for restarting the timing sequence whenever the format of the sensed biological signal falls outside of the predetermined limits.

Abstract: ABSTRACT OF THE DISCLOSURE        A method for laying a snow road or an airplane runway on a snow or ice covered surface includes the removal of a predetermined and relatively small portion of the snow or ice surface, which is melted to water and mixed with the snow or ice remaining on the snow surface.  The mixture of water and snow or ice is leveled so as to form a road surface when the mixture freezes.  Preferably, the snow remaining on the surface is mechanically worked with a rototiller, while the melted snow is injected into the snow being worked.  The method is particulary advantageous in that it can be carried out without requiring melting of all the snow necessary to form the snow road, or requiring the addition of any water from an external source, other than the portion of snow removed from the snow surface.   An apparatus for performing the method is also described.
