Abstract: A pacemaker having an electrical stimulation source of known type is provided with a sense amplifier having a switched capacitor circuit which allows switching of the amplifier's bandpass frequency characteristic thereby selectively varying the cardiac signal frequencies subject to sensing.  The heart's electrical activity is detected on a first predetermined bandpass frequency range prior to delivery of a stimuli and a second predetermined bandpass frequency range displaced from the first range after delivery of the stimuli to verify capture of the heart by the stimuli.
Patent CA-2008505-A1 (CA)
IPC: H04M3/30
Filed: 1990-01-24
Abstract: ABSTRACT OF THE DISCLOSURE    Corruption of communication signals on a telephone line by the direct (low impedance) interfacing of test equipment to the line  is  precluded  by  a  protective  interlock  circuit,  which prevents the test set from seizing the line if data traffic is present. The  interlock  circuit  is  coupled  between  the  line circuit to be accessed and the test equipment,  and includes a multiple band frequency detector, which monitors the line for signals  lying  within  (in  and  out-of-audio)  frequency bands.          Should the detector identify any traffic within its sensitivity range (out of the audio band) during the interval of a timing pulse produced by the  closure of a switch,  the logic level applied to combinational logic will change state and prevent the generation of a test set enabling signal. The test set enabling signal is normally coupled to a 'line-seize' transistor circuit within the test set, so that, without this enabling signal, the test set is effectively locked-out from the line and data cannot be corrupted. Should the frequency detector not have produced an out of audio band detection signal after the expiration of the timing pulse, the combinational logic circuit and an associated flip-flop generate  an  output  signal  for  enabling  the test equipment to seize the line. The flip-flop remains set and the logic level of the output signal is maintained until the line is no longer seized by the test equipment.

Title: Method and apparatus for detecting defects in pneumatic tire

IPC: G01M17/02
Filed: 1990-05-10
Abstract: METHOD AND APPARATUS FOR DETECTING DEFECTS IN PNEUMATIC TIRE                 Abstract of the Disclosure Internal defects formed within a substrate tire for manufacturing a retreaded tire are detected in a non-destructive manner by rotating the inflated tire at a constant speed of 1 r.p.m. while a displacement sensor is urged against an outer surface of the tire at different pressures to derive first and second sets of displacement signals, deriving displacement differences between the first and second displacement signals at corresponding measuring points on the outer surface of the tire, deriving a minimum value of the displacement differences, calculating deviations between the displacement differences and the minimum value, deriving the maximum deviation, and by comparing the maximum deviation with a first threshold value.  When the maximum deviation exceeds the first threshold value, it can be judged that the tire includes a local separation. Further an average of the displacement differences is derived and is compared with a second threshold value. When the average of the displacement differences exceeds the second threshold value, it is judged that the tire includes a circumferential separation or fatigue. Moreover, a standard deviation of the displacement differences is calculated and is compared with a third threshold value.  When the standard deviation exceeds the third threshold value, it is judged that the tire has the circumferential separation or fatigue.

Abstract: Abstract of the Disclosure The present invention relates to a tamper indicating tape made from a film capable of splitting internally for use with a package to indicate opening of the package.  In grocery stores, packages are subject to entry by various classes of tamperers.  One type of tamperer opens the package, consumes the contents thereof, reseals the package, and places the resealed package back on the shelf.  Another type of tamperer opens the package, introduces a foreign object therein, reseals the package, and then places the resealed package back on the shelf. This invention provides a tamper indicating tape for use with a closure or container.  The tape comprises a film including phase separated polymers.  Colored indicia are applied to opposing major surfaces of the film indicative of a condition that someone has tampered with the tape, e.g., tape removal and reattachment, or abrading.  The film further bears a layer of adhesive thereon as a means for adhering the tape to a portion of a container or to a closure tape on a can lid.  When the film of the tamper indicating tape is internally split, one set of colored indicia is obscured and the other set of colored indicia is rendered perceptible.  When the film is abraded to remove the perceptible set of colored indicia, the aforementioned obscured set of colored indicia is rendered perceptible.

IPC: D21F/
Filed: 1990-06-05
Abstract: A method and apparatus in the press section of a paper machine for regulating the axial linear-load profiles in its nip or nips (N1,N2,N3).  The axial temperature profile(s) of the outer mantle(s) of a press roll or rolls (11, 13, 16, 17) is/are regulated.  Thereby, the distribution of the diameter of the press roll in the axial direction is controlled on the basis of thermal expansion.  Also thereby, the distribution in the transverse direction of the machine of the linear load in the press nip or nips (N1,N2,N3) formed by the press roll or rolls (11, 13, 16, 17) is affected.  The temperature profile of the outer mantle(s) (11', 13', 17') of the press roll or rolls (11, 13, 17) is regulated by a press felt or felts (10, 14, 18) running through the press nip or nips (N1, N2, N3) formed by the roll applying a heating/cooling effect whose profile in the axial direction of the roll is regulated, and/or by applying a set of water jets (F) directly onto the outer mantle(s) of the press roll or rolls, the jets' quantity distribution (Fl...FN) and/or temperature distribution (Tl...TN) being regulated so as to obtain the desired distribution of nip-pressure profile.
