Patent CA-2047559-A1 (CA)
Inventor: HERMAN FRED W
IPC: G01V3/12
Filed: 1991-07-22
Abstract: A batteryless, portable, frequency divider includes a first resonant LC circuit that is resonant at a first frequency for receiving electromagnetic radiation at the first frequency; and a second resonant LC circuit that is resonant at a second frequency that is one-half the first frequency for transmitting electromagnetic radiation at the second frequency.  The first circuit is coupled only magnetically to the second circuit to transfer energy to the second circuit in response to receipt by the first circuit of electromagnetic radiation at the first frequency.  At least one of the resonant circuits includes a variable reactance element, such as a variable capacitance diode or varactor.  In a variable reactance element of the first circuit, the reactance varies with variations in energy received by the first circuit for causing the second circuit to vary in reactance due to mutual reactive coupling to cause the second circuit to transmit electromagnetic radiation at the second frequency in response to the energy transferred from the first circuit at the first frequency.  In a variable reactance element of the second circuit, the reactance varies with variations in energy transferred from the first circuit for causing the second circuit to transmit electromagnetic radiation at the second frequency in response to the energy transferred from the first circuit at the first frequency.  Both resonant circuits include inductance coils that are disposed on a ferrite rod, for enhancing the magnetic coupling.  The frequency divider is included in a tag utilized in a presence detection system.

Title: Voltage controlled power supply
Inventor: WINTER MARLAN L
IPC: H01H47/32
Filed: 1991-12-06
Abstract: A B S T R A C T VOLTAGE REGULATOR, POWER SUPPLY AND CALIBRATOR     A  control  circuit  for  electrical contactors, starters and the like which include  one or  more pairs of separable main  contacts is controlled by an electromagnet assembly 10.    In  order  to  reduce,  if  not eliminate, audible noise generated by the electromagnet assembly, the electrical  current  to  the  electromagnetic  assembly is regulated to  minimize the rate of change of magnetic flux therethrough to thereby reduce, if not  eliminate, audible noise.   The circuitry  is also  adapted to compensate for alternating current (AC) magnetic  coupling from  the main poles  in  order  to  provide  a relatively larger hold in force when the contacts  are to  remain in  a closed posi-tion.   Apparatus for  calibrating an electrical device is taught.  A precision power supply device PCS  is intercon-nected by  way of appropriate input channels to the device 10 to  be  calibrated  for  supplying  a  precise accurate calibration variable  as an input.  A personal computer PC is interlinked by way  of  a  communications  network CONI with  the  apparatus  10  to  be  calibrated and  is also interlinked with the precision  supply device  so that the personal  computer  PC  has  available  the exact value of input  variable  utilized.  Upon  command,  the personal computer  PC  instructs  the  device  being  calibrated to deliver to the personal computer PC those values  of input variable which  the device  being calibrated interprets as the  input  variable  value.    The  personal  computer PC compares this  value with the actual value and generates a correction factor which  the  personal  computer  PC sends back  to  the  device  being  calibrated for storage in an EEPROM.  A power supply  202  which  includes  a rectifier input circuit MCR1 which provides either half wave or full wave  rectified  electrical  current  at  an instantaneous voltage value to the input terminal of a controlled switch MQ3 is taught.  The controlled switch is controlled by the combination  of  a  "low  voltage  reset" device MU6 and a field effects  transistor MQ2  combined to  form a voltage sensing and  switching circuit SSM which is interconnected at its input between the. input  terminal  of  the voltage regulator and  ground and  at its output or reset terminal to the control terminal of  the  voltage  regulator.   The output terminal  of the  voltage regulator is connected to the anode  of  a  diode  MCR7,  the  cathode  of  which is connected to one side of a storage capacitor MC6.

Title: Liquid jetting device having a mechanism for introducing a bubble into a liquid chamber and recording apparatus using the device
Inventor: YANO KENTARO
IPC: B41J2/055
Filed: 1992-01-17
Abstract: Delay of refilling to be conducted immediately after the first discharge in the continuous discharge can be restricted.      Adequate air bubbles which do not adversely affect discharge can be formed by means of the air bubble forming unit, such as a sub-heater for heating the ink in the ink reservoir portion, such as a common liquid chamber. The formed air bubbles function as the buffers and thereby absorb the discharge energy (pressure waves) directed toward the common liquid chamber during discharge to restrict flow of the ink in the direction opposite to the discharge port. That is, refilling after discharge can be quickly performed.

Abstract: ABSTRACT        An FM/CW radar system is disclosed for determining a safe stopping distance between a moving vehicle and a potential obstacle. The radar signal is modulated linearly over several slopes. A microstrip phased array transmit/receive antenna is also disclosed having a hybrid tap, corporate feed structure.          Signals from the antenna are amplified and filtered, and passed through an analog to digital converter to a signal processor, which performs a Fast Fourier Transform on the signals to convert them from time  domain  data  to  frequency  domain data.  The frequency domain data is then used to solve target range and Doppler equations, determine safe stopping distances, and sound or  display alarms  if  the  safe  stopping  distance  has  been violated. A sensitivity control adjusts for road conditions or operator reaction time variations.

Inventor: SAUVE DENNIS L
IPC: E04B1/70
Filed: 1992-03-31
Abstract: A hollow rectangular concrete building block is provided having features which prevent and impede the infiltration of water into and migration of water through the block. The hollow block conventionally includes parallel interior and exterior vertical walls with at least one transverse vertical web spanning between the walls to form a unitary block with an interior cavity. Migration of water from the exterior to interior is impeded by a plurality of vertical ribs protruding from each side surface of the web. Water which has penetrated into the block cavity is redirected downwardly, as it trickles acrossthe web, by the ribs to be ultimately expelled at the base of the block array with conventional flashing and weep holes. Grooves in the upper surface of the webs prevent migration of water along the upper surface and redirect the water to flow downwardly along the side surfaces of the web. The upper exterior edge of the exterior wall of the block may preferably be beveled particularly in the application of the invention to architectural masonary units where the mortar beads may be inset from the block faces up to 3/4 of an inch for visual effect. Bevelling the exterior edge is done to prevent pooling of water in the mortar joint area; to shed water downwardly along the exterior surface of the exterior wall; and to enable access to the joint for sufficient compaction of the mortar joint prior to setting, thereby minimizing cracks in the finished mortar through which water may infiltrate into the block cavity.
