Patent CA-2112058-A1 (CA)
Inventor: HAUCK JOHN A
IPC: A61N1/365
Filed: 1993-12-21
Abstract: A cardiac pacemaker signal processing circuit adapted to obtain an evoked ECG signal. The circuit senses the electrical signals of the ring and tip electrodes in the unipolar mode from the bipolar lead after the electrical pacing stimulus has been applied to contract the ventricle of the heart. The residual oppositely polarized potentials at the ring and tip electrode, as well as the sensed evoked ECG signals, are added together to cancel out the opposing residual potentials, but to add the common polarized ECG signal. Thus, a high quality evoked ECG signal is obtained, free of the residual potentials, and subsequently utilized by R-wave detection circuits for sensing the QRS complex. The circuit includes compensating signal processing circuits to provide time domain signal processing weighting functions to match exponential time delay of the tip and ring electrodes, and includes amplitude adjusting compensation as well. Thus, the absolute amplitudes of the opposite polarized residual potentials will be adjusted to be equal, are summed, and canceled or nulled at the appropriate time in the time domain. Both biphasic and triphasic pace pulse techniques are not required, the pace pulse amplitude can be reduced to extend the battery life of the pacemaker. Further, the post pace re-charging cycle is only interrupted and undertaken passively to, again, reduce current drain on the battery. Classic R-wave detection circuits are adaptable to the signal processing circuit of the present invention. <IMAGE>

Abstract: Microwave variable power divider, comprising (Fig. 1) a 3 dB directional coupler (1) (called hybrid circuit), followed on one output leg by a variable phase shifter, obtained by assemblying a -3dB directional coupler (2) with its outlets closed on movable short-circuits (6; 7) that can ensure its variability, and on the other by a 90-degree differential phase shifter (5) and an analogous variable phase shifter consisting of directional coupler (3) and movable short-circuits (8; 9), followed by another directional coupler (4). The device makes it possible to vary the power on the two output legs (12; 13) in a complementary manner by regulating the movement of the movable short-circuits.      The particular solution proposed allows the use of a planar-type technology, which can assure considerable advantages in terms of construction, dimensions and integration in more complex networks. In addition, the operating bandwidth (~ 16%) associated with low losses (0.15 dB) and minimal inband variation of amplitude at the outputs in relation to any desired power division value constitute the peculiar characteristics of this device. Lastly, the low level of passive intermodulation products allows the device to operate in multicarrier systems and the particular movable short-circuit solution adopted allows it to be used for medium-high powers (300 W in continuous wave radiofrequency).

Title: Steel building design incorporating thermal break with integral underfloor
Inventor: KRISSTTOVVV S
IPC: E04B1/24
Filed: 1994-03-16
Abstract: Each design component in this steel building system is essential to the overall performance of the completed structure. The double wall system with the outer studs attached to the main floor joists and the inner wall placed on top of the subfloor makes for structural integrity superior to that of wood frame designs.    The stacked floor joist design, dual wall design and the separation of the walls at the top allows the urethane foam insulation to completely envelop the structure. The thermal break and vapor barrier created by this design exceeds the R2000 residential standards set out in Canada.    The use of light gauge steel under the floor system and as a joist header allows the structure to be placed on blocks without threat from insects and rodents.    The floor joist design allows the furnace to be placed anywhere on the subfloor of the structure and the absence of ductwork allows vents to be cut anywhere on that same floor. The result is increased mechanical freedom, a warm floor and increased air flow pressure.

Abstract: An  order  amount of parts can be  calculated  from  an actually  used amount of the parts, so that the  used  parts can be resupplied subsequently.  An order amount can also be calculated  form  a  production  plan,  so  that the  parts necessary to meet the plan can be delivered.    In this technique, an order amount is calculated by the equation  "W1~X' + W2~X2", where X1 is  the order  amount calculated  in  a subsequently resupplying way,  X2 is the order amount calculated in a plan correspondence way, W1  is an  actual  weight,  and W2 is a plan  weight.   The  actual weight  W1 becomes high and the plan weight W2  becomes  low when the subsequently resupplying way is suitable, and  vice versa.   The actual weight W1 and the plan weight W2 can  be calculated from experience or system analysis.

Title: Method and apparatus for bending tubes using split bend die
Inventor: SCHUCHERT EUGENE H
IPC: B21D7/024
Filed: 1994-09-30
Abstract: Method and apparatus for bending serpentine heat exchanger tubes using a split bend die having a relatively short upper die section with a straight back end. After the tube is bent in conventional manner using a clamp die and a pressure die, the bend die is split along a shaft and rotated through a predetermined angle to position the straight back end substantially parallel to a straight segment of the tube at the output of the bend die. The input segment of the tube is then moved next to the shaft in preparation for rotating about the input segment to raise the output segment above the upper section of the bend die.    Such lateral motion reduces the segment spacing required for clearance of the upper section. Other features for reducing the spacing are providing an indentation on the shaft, angling the back end with respect to the sides to provide a minimum length, and truncation an upper portion along the back end.
