Abstract: ABSTRACT OF DISCLOSURE       A strain wave gearing  comprising a circular spline, flexspline  inside  the circular  spline,  a wave generator for deforming the flexspline into, for example, an ellipsoid and a motor for rotating the wave generator to produce a relative rotation between the flexspline and the circular spline.  The strain  wave  gearing  is  sometimes  termed  a  harmonic  drive transmission,  and  there  is  a  type  of  gearing  called  flat-shaped strain wave gearing which is composed of two circular splines  juxtaposed  with  each  other,  a  flexspline  in  the circular splines having the same number of teeth as the first circular spline, a wave generator for deforming the flexspline into an ellipsoid and a motor for rotating the wave generator.    In the flat-shaped gearing,  each tooth of the flexspline is provided with a convex tooth face and a concave tooth flank.          The tooth profile of the first circular  spline  is given by such a locus curve that the tooth face of the flexspline plOtS when the deformed configuration of the flexspline is rotated by  the  wave  generator,  and  the  tooth  depth  of  the  first circular spline is made equal to or larger than the working depth of the flexspline.   Thus,  the teeth of the flexspline engage with those of the first circular spline in the broad extent of the engagement region.

It further includes a control vector checking means having an input coupled to the control vector register, for checking that the control vector authorizes the cryptographic function which is requested by the cryptographic service request.  It further includes a hash function generator having an input coupled to the control vector register and an N-bit output, for mapping the control vector output from the control vector register, into an N-bit hash value.  A key register is included for storing the N-bit cryptographic key.  It further includes a logic block having a first input coupled to the N-bit output of the hash function generator, and a second input connected to the key register, for forming at the output thereof a product of the N-bit key and the N-bit hash value.  Finally, an encryption device is included having a first input for receiving a cleartext data stream and a key input coupled to the output of the logic block, for forming a ciphertext data stream at the output thereof from the cleartext data stream and the product.

Granted: 1992-08-18
Abstract: ABSTRACT OF THE DISCLOSURE    A high  density  backplane (HDB) connector  is  provided  for electrically   interconnecting   high density   printed   circuit boards.    The  printed  circuit  boards  have  a  predetermined geometric conductive pattern which includes high density arrays of  individual  signal/power  contact  interconnects  and  unitary ground  strips.   The  HDB  connector  comprises  a  housing  module secured to one board and a stiffener module secured to a second board.   A compliant contact  module mounted within the  housing module  includes a resilient member,  an insulator member having arrays of free-floating rigid contact pins disposed therein, and a flexile film interposed therebetween.  The flexile film has a signal/power  conductive  matrix  formed  on  one  side  and  a continuous ground plane formed on the other side.  The compliant contact  module  further  includes  prestressed  early-mate  ground contacts  and  a  plurality  of  distributed  resilient  ground contacts.   Circuit  board  mating  is  effected  by  pressing  the stiffener module down onto the housing module.  The prestressed early-mate ground contacts exert forces to bias the second board away from the rigid contact pins.  Further downward movement of the  stiffener  module  causes  a  camming  coaction  between  the stiffener module and the housing module to urge the second board into  mating  engagement  with  the  rigid  contact  pins  and  the distributed resilient ground contacts.   Final downward movement of  the  stiffener  effects  a  wiping  action  between  contact interconnects.
