Title: Diversity coding for transparent self-healing communications networks
Inventor: AYANOGLU ENDER
IPC: H04L1/02
Filed: 1990-09-27
Abstract: This invention is a technique for the susbtantially instantaneous self-healing of digital communications networks. Digital data streams from each of N nearby sources are combined and encoded to produce N+M coded data streams using a coding algorithm. The N+M coded data streams are then each transmitted over a separate long haul communications link to a decoder where any N of the N+M coded data streams can be decoded uniquely to produce the original N data streams. The original N data streams are then distributed to their respective separate end destinations. If any M or less of the N+M long haul communications links fails, i.e. as in a telephone line that gets cut or a long distance switch that fails, no rerouting of traffic need be done. Rather, the receiver detects loss of carrier on the failed link(s), and immediately supplies the missing data by decoding the data from the at least N remaining links. The technique overcomes a long felt problem of trying to reroute traffic by using sophisticated resource allocation techniques when a communications link fails.

Title: Sealed variable resistor
Inventor: MASAKI KAZUMI
IPC: A61N1/32
Filed: 1990-11-23
Abstract: Abstract of the Disclosure The disclosure relates to an improvement of a sealed variable resistor which comprises enclosing a variable resistor and an arm member attached to a shaft of the variable resistor in a sealing container, and rotatably supporting a dial knob about a shaft outside the sealing container such that when the dial knob is energized, the arm member moves in association by virtue of magnetic force.  The reliability and operability of such  a  sealed variable  resistor  are  extremely  improved by forming the arm member and dial knob into a circular plate, and attaching to the arm member and dial knob at least two magnet pairs apart from each other.  These render the sealed variable resistor very useful in various electrical devices which may be exposed to moisture when in use.

Title: Anti-reflective transparent coating
Inventor: DEMIRYONT HULYA
IPC: G02B1/11
Filed: 1991-10-09
Abstract: An anti-reflective coating employing Si1-xHx as a high refractive index material in a film pair together with SiO2 as a low refractive index material is found to be substantially transparent to visible light and to provide good anti-reflectance where the Si1-xHx film is ultra-thin, preferably less than about 80 Angstroms, and the thickness of the SiO2 film is matched to that of the Si1-XHx film. Laminated glazing units having such antireflective film can be used, for example, even in applications requiring high transmittance of visible light, such as motor vehicle windshields, in view of the substantial transparency of the coating.
