Patent CA-1187140-A (CA)

Abstract: ABSTRACT Conventional digital modems have not been applicable to pacemaker telemetry systems since their use would require the periodic conversion of analog data to a numerical value prior to transmission.  In contrast, the pulse interval telemetry system of the present invention is capable of transmitting analog data without conversion to a numerical value, and is capable of sequen-tially transmitting both digital and analog data.  This data is individually and serially transmitted in either an analog or digital format to a remote receiver.  The apparatus of this invention includes a resonant tank circuit for producing a radio frequency carrier signal.  This tank circuit is operative at periodic intervals determined by the output frequency or period of a variable frequency oscillator (VFO).  Thus, the VFO output modulates the time interval between consecutive pulses of the carrier signal.  Sources  of digital and analog information are interfaced to the VFO to vary the VFO output period.  In the digital mode the VFO output is varied to a first preselected period to encode a logic one, and to a second preselected period to encode a logic zero. In the analog mode the VFO output is continuously variable over a limited range about a nominal time period to encode the analog data.  An additional feature of the invention is the use of the VFO output to synchronize the translation of digital data from a parallel format in memory to a serial format suitable for telemetry transmission.

Abstract: Abstract of the Disclosure A  forging  (A)  is  received  in  a  split  ring  (B)  which provides peripheral support to a forging peripheral wall  (14) and an upper peripheral flange (16).  The forging and the split ring are supported by a nest member assembly (C) as a trimming assembly (D)  moves  longitudinally to trim the forging flange and a forging bore (10).  A punch (74) with a hardened cutting edge (80) moves axially through the forging bore and interacts with a nesting assembly cutting edge  (60)  to trim the bore.      Concurrently,  a  trim  die  (90)  having  a  cutting  edge  (96) interacts with a split die cutting edge (36) trimming the upper flange.   The  split  ring  restrains  a  central  portion  of  the forging  from puffing peripherally outward in response to the punch being urged therethrough.   The  interaction of the trim die and the split ring inhibits the upper part of the forging adjacent the  upper  flange  from  being  drawn  in  toward  the forging bore by the interaction between the punch and forging.          In  this  manner,  the  forging  bore  and  flange  are  trimmed concurrently and deformation of the forging is restrained.

Abstract: ABSTRACT OF THE DISCLOSURE           A frequency multiplier for electromagnetic waves in which multiples of the input frequency propagate, while the in-put frequency evanesces.  A rectangular waveguide or other suit-able wave conveying element with a cut-off frequency above the input frequency but below the output frequency contains the mul-tiplying structure.  The input frequency is multiplied using a post located in the waveguide or other element adjacent to the source of input waves.  The post may define a multiplier gap between one of its surfaces and a wall of the waveguide or other element, in which case the multiplier gap may contain a multi-pactor between its surfaces which generates multiples of the input frequency.  The multiplier gap may alternatively contain a non-linear element responsive to a high electric field, such as a ferroelectric material, which also generates multiples of the input frequency.  Alternatively, the post may be surrounded by a non-linear element of ferromagnetic material responsive to a strong magnetic field.  In either embodiment, waves at the same frequency as the input waves cannot propagate, but waves above the cut-off frequency propagate through the waveguide or other element to an output aperture.
