Patent CA-2138923-A1 (CA)
Title: Ramp generator
Inventor: CAPENER PAUL H
IPC: H03K4/501
Filed: 1994-12-22
Abstract: A ramp generator has an integrator, which provides a ramp output, and a counter, which counts a clock signal during the rise period. The counter and clock are arranged so that when the actual rise time is equal to the desired rise time, the counter overflows and returns to zero. If the rise time is too slow, the counter will contain a count at the end of the rise period. A register is connected to receive this count and an adder adds the contents of the register to the contents of the adder repeatedly each time a clock pulse is generated. The adder has an output connected to the input of the integrator and, each time the adder overflows, supplies a correction pulse to the integrator so that its rise rate is increased.

Title: Magnetomechanical eas components integrated with a retail product or product packaging
Inventor: WINKLER STEPHEN
IPC: G08B13/24
Filed: 1995-06-27
Abstract: An inventory of goods is protected from theft by means of electronic article surveillance (EAS) markers integrated with items of the inventory.  Each such item has a structural member in which a cavity is integrally formed. A respective magnetostrictive element is housed, free of mechanically clamping constraint, in each cavity.  A respective biasing element is located adjacent to the cavity on each such item of inventory.  The biasing element provides a magnetic field to bias the respective magnetostrictive element.  EAS equipment is provided at a retail store where the inventory  is  maintained.    The  EAS  equipment  generates  an alternating electromagnetic interrogation field, and when an item of inventory having the integrated EAS marker is exposed to the interrogation field, the biased magnetostrictive element is excited into mechanical resonance that is detected by the EAS equipment.          Alternatively,  the  integrated EAS marker includes  a magnetic element  that  provides  a  harmonic  signal  in  response  to  the interrogation field, and a lubricant coating is provided on the magnetic element to prevent transmission of mechanical stress to the magnetic element.
