Title: Method for the production of a self- balancing code of the 3b2t type
Inventor: SIDDIKI ABU B
IPC: H03M5/18
Filed: 1990-06-01
Abstract: This code may used for the digital transfer of information signals along digital subscription tracts. It fully balances the constant ingredient of the energy spectrum of the linear signal that is not dependent on the statistical properties of the signal, and creates a good opportunity for bloc synchronization with forbidden code combinations by increasing the distance of transmission along digital subscriber tracts. By this method, each binary combination of three symbols (3B) is initially transformed into a ternary code combination of two symbols (2T) on the compound algorithmic code 3B2T. After that, two of the received ternary symbols (1, 2 and 0) are transformed into two counter-phase bi-impulses, while the remaining of these symbols - into a ternary zero.

Abstract: ABSTRACT OF THE DISCLOSURE    A compression tool (10) crimps both cylindrical (12) and "H" type (75) connectors.  The jaws (22) of the compression tool have a first part which is defined by a nib area in which there is a nib (44) on either jaw and a base nib (46) which is moved into the nib area by a yoke (36) which is in turn moved by a manually operated hydraulic section (18) of the tool.  Operation of the hydraulic section causes the nibs to converge upon a connector placed therebetween to effect the crimp.  Alternatively, a connector, e.g., an "H" type connector, may be placed in a second part of the jaws.  The second part includes opposing "C" shaped sections which also effect a crimp in response to the hydraulic operation.  Additionally, the tool is adaptable to receive dies (76 and 78) which allow customized crimping and cutting.

Abstract: A communication network is comprised of a first, second, third and fourth controller node in line communication. Each controller node includes a microprocessor. Each microprocessor is programmable to respond to and generate data message bytes, each data byte having one start bit, eight data bits, one programmably settable bit and one stop bit. Each microprocessor is further programmable to respond only to a unique address-command data message byte from a message source node. The address-command byte is recognised because the settable bit is set. Each microprocessor is programmed to generate a reply message byte with the ninth bit not set and to then receive from the source node a message count byte followed uninterrupted by the data message bytes. Upon receiving a complete data message conforming to the received count of the count byte, the microprocessor then generates an acknowledgement byte.

Abstract: A MULTIPLEXING SYSTEM FOR DISTRIBUTION OF DIGITAL DATA              ABSTRACT OF THE DISCLOSURE         A  multiplexing   and   distribution   system is provided for use in a digital data distribution system for multiplexing  block  data  which  represent  predetermined quantities of  information with stream data  representative of  a  continuous  flow  of  information  onto  a   single distribution channel.   The multiplexing system utilizes  a framing technique in which fixed time intervals, or frames, are provided along the distribution channel.  The start of each frame is defined by one or more digital bytes which represent  frame  synchronization  characters.   A  stream control character is inserted in each frame after the frame synchronization  characters.   Consecutive  stream  control characters may be concatenated to provide a control channel which contains information used to select which particular stream data channels are to be multiplexed, and where the data  is  to  be  placed  within  the  frame. A multiplexer controller  selects  the  particular  stream  data  channels which  are  to  be multiplexed,  and  inserts successive one byte increments of each of these stream data channels into each successive frame after the stream control character.          The  remaining  space  in  each  frame  is  filled  with consecutive block data.  The frame of data, which now has particularly selected stream channels multiplexed with the block data,  may be sent to a forward correction encoder which  incorporates  appropriate  forward  error  correction code,   and  then  to  a  modulator  which  modulates  the multiplexed data onto  a  base  frequency  for  distribution along a single distribution channel.

Abstract: The illustrated action toy apparatus comprises an incrementally advancing catcher unit that may be in the form of an animated character such as a shark.  The unit moves along a succession of areas of a path.  Objects which may represent fish or the like are disposed on the areas. A fish on one area is caught or "eaten" by the shark when the shark reaches that area.  As the shark advances to an area, its forward end rises to an elevated position to permit that end to pass over and then come back down upon a fish on that area.   The forward and up and down movement of the illustrated shark unit is provided by a motor-driven cam.  To maximize continuous playtime, the shark unit is tethered to the center of a gameboard so that it travels around a circular path on the board.

Abstract: ABSTRACT             In a reel assembly of a tape cassette a one-way clutch mechanism is provided which serves to prevent rotation of the reel in the direction required for the purposes of rewinding a tape thereon.  The one-way clutch mechanism includes a slipway channel which extends circumferentially of the axis of rotation of the reel.  The reel assembly includes a first clutch member which is designed to be driven by the power output shaft of the winding mechanism and a second member which is designed to be held fast with respect to the cassette.  A slipway channel is formed at an interface between the first and second clutch members such that a portion of the channel is formed in the first member and a portion of the channel is formed in the second member.  A pawl displacing ring is mounted in the slipway channel so that it bears against the second member and is drivingly connected to the first member by means of a pawl.  The pawl is pivotally mounted in the first member and is movable between a retracted position out of engagement with the second clutch member and an extended position in which it engages the second member to prevent relative rotation between the first and second members.   The displacer ring serves to displace the pawl outwardly from its retracted position to its extended position in response to rotation of the first member in the second rotational direction.
