Inventor: ELASCHUK BILLY B
IPC: A61D19/02
Filed: 1989-12-22
Abstract: SYSTEM AND METHOD FOR DETECTING ESTRUS OR STANDING HEAT IN ANIMALS          ABSTRACT OF THE DISCLOSURE  It is desirable to be be able to ascertain the ideal time to administer the semen in the artificial insemination of  animals  such  as  cattle,  in order  to maximize the success rate of such insemination and to endeavour to eliminate the missing of the estrus cycle altogether.   This invention includes a pressure sensor detachably  secured to the back of  the  female  animal adjacent the base of the tail  in which the pressure sensor is actuated by the weight of an animal mounting the female.  The pressure sensor transmits a signal to a remote location indicating the initiating and duration of the mount.  The receiver also records the time and date and  a time  delay may be  provided  in  the  sensor/ transmitter  circuit  to  eliminate  the  recording  of mounting  times  having  a  duration  shorter  than  a preselected time period which are of no value to the determination of maximum of peak estrus.

Title: Method for detecting and tracking moving subjects in a digital image sequence having a stationary background
Inventor: KARMANN KLAUS-PETER
IPC: G06T7/246
Filed: 1990-02-27
Abstract: ABSTRACT OF THE DISCLOSURE    A method for detecting and tracking moving subjects in  a  digital  image  sequence  having  a  stationary background  by  comparing  the  image  sequence  to  a calculated background image sequence, whereby a sequence of binary subject masks is calculated whose segments reproduce  the  shapes  and  positions  of  the  moving subjects, and whereby the motion vectors of the moving subjects  are calculated by matching these  segments.          Also, a sequence of background images is calculated by spatially  selective  and  chronologically  recursive averaging of the input image sequence in which the moving subjects  are  not  contained  but  in  which  other modifications of the background that are not caused by moving subjects are contained.  Further, a sequence of binary subject masks is calculated by binarization of the difference image sequence from the input image sequence and the background image sequence using a threshold whose value is used for controlling the spatial selectivity in the calculation of the background image sequence and whose segments are determined together with their sizes and center of gravity positions.  Finally, motion vectors of the detected subjects are determined by minimization of the squared gray scale value differences averaged over the intersection of the shifted mask segments, whereby differences between the center of gravity vectors of corresponding segments are utilized as start vectors in the minimization.
Patent CA-2011130-A1 (CA)
Inventor: KRUDE WERNER
IPC: F16H9/10
Filed: 1990-02-28
Abstract: ABSTRACT OF THE DISCLOSURE     A continuously variable transmission system having a fixed variable diameter pulley connected by a drive belt to at least one other pulley.  A tensioner pulley maintains the tension on the drive belt within predetermined limits as the effective diameter of the variable diameter pulley changes.  The effective diameter of the variable diameter pulley is determined by a balance between a resilient force biasing a plurality of belt engaging members in a predetermined direction and a radial force acting on the plurality of belt engaging members in the opposite direction.  In a first embodiment, the resilient force biases the plurality of belt engaging members outwardly and the radial forces are generated by displacing the ten sioner pulley to increase the tension on the drive belt.  In an alternate embodiment, the plurality of belt engaging members are biased inwardly by a resilient force and are displaced outwardly by centrifugal forces.

Title: Making pressed board
Inventor: FISCHER TILMAN
IPC: B27N3/08
Filed: 1990-04-24
Abstract: A fiber or chip board is made by first forming a mixture of a binder and particles having a relatively low moisture content that is substantially less than a relatively high moisture content that a finished board should have.  This mixture is deposited as a mat on a movable substrate so that the mat is substantially at ambient temperature and has the relatively low moisture content.  Then the mat is preheated with steam to raise its temperature and to increase its moisture content to the predetermined relatively high moisture content.       The thus preheated mat, whose moisture content has been corrected, is then simultaneously heated and compressed to form it into a board.

A second diode bridge comprising a pair of oppositely-biased diodes extends between a second pair of junctions on the circuit legs located between the squibs  and the crash sensors thereof.   A third diode bridge comprising oppositely-biased diodes connected in series also extends between the latter pair of junctions on the circuit legs.   A third crash sensor connects a junction on the third diode bridge between the diodes thereof with both circuit legs, respectively, so as to be placed in parallel with the crash sensors thereof.          The diode bridges provide multiple firing paths for both squibs  to  ensure  deployment  of  both  air  bags  upon simultaneous  closure of either  safing  sensor and any crash sensor.   Full circuit diagnosability is achieved through a comparison of the voltages achieved about the circuit  and  the  effects  thereon of incrementing  the supply voltage and/or the operation of a plurality of current drains connected about the circuit.
