Patent CA-2028714-A1 (CA)
Inventor: GRASSO GIORGIO
IPC: H04B10/12
Filed: 1990-10-29
Abstract: An optical fiber and an optical amplifier, in particular for optical fiber telecommunication lines operating with a transmission signal in a predetermined wavelength range.  The amplifier comprises laser emitting active optical fiber doped with erbium and a further doping substance, distributed along the fiber.  The further doping substance has an absorption for a light having a wavelength lower than 1,540 nm substantially higher than the absorption that the further doping substance shows for a light having a wavelength varying from 1,540 nm to the upper limit of the predetermined wavelength range of the transmission signal.  Preferably, the further doping substance is samarium.  Samarium contained in the fiber is capable of absorbing the spontaneous erbium emission, which would constitute a noise source, thereby allowing a communication signal to be amplified in a wavelength range corresponding substantially to the tolerance range of the commercially available laser light emitters used as the communication signal source.

Abstract: In a weapon system 10 incorporating a target position sensor (14), an information system (16), a power source  (24),  a launcher  (20),  and an airborne vehicle (18),  a  launcher  control  system  (12)  incorporates  a communications   interface   (26)   for   coupling   the information system (16)  and the target position sensor (14)  to a launcher (20)  and an airborne vehicle  (18). The  communications  interface   (26)   receives  target position information and launch and control orders and provides  launcher  and  airborne  vehicle  status.   A airborne vehicle interface (28) couples the launcher (20) and the airborne vehicle (18) to the information system (16)  and  a  power  source (22).   A  transmitter  (30) communicates updated target position information to the airborne vehicle after launch.   A power control means (32)  converts and regulates power from different power sources (22) to be used by the launcher control system (12).   The launcher  (20)  with launcher control system (12)  is  preferably  modular  in  construction  and  is separate  from the information  system  (16)  and  target position sensor (14).

Abstract: A unique cellular telephone (100) digitally frequency locks to the received base station transmitter signal. The cellular telephone (100) includes a radio transceiver (106), a reference oscillator (104), and microcomputer (102) with memory therein for controlling the operation thereof. The radio transceiver (106) includes a phase-locked loop (PLL) synthesizer 120, a receiver mixer (122) followed by one or more gain stages (124), a phase detector (126), and a divider (128). The PLL synthesizer (120) generates a signal locked to the reference oscillator (104) that is mixed with the incoming base station transmitter signal in the receive mixer (122) to generate an intermediate frequency signal. The output of the reference oscillator (104) also feeds the divider (128), which divides the reference oscillator signal by an amount so as to generate the divided signal having a frequency substantially the same as the frequency of the intermediate frequency signal from the mixer (122). The output of the divider (128) and the amplified intermediate frequency signal from the amplifier (124) are both fed into the phase detector (126), which generates a binary error signal (110). The microcomputer (102) is responsive to the binary error signal (110) for frequency locking reference oscillator 104 to the received base station transmitter signal.

Abstract: A method and apparatus for linear vocal control of cursor position within a  computer display  system.   A microphone is utilized in conjunction with a computer system  to  detect  vocal  utterances  and  each  vocal utterance  is  then coupled  to  an  analysis  circuit  to detect voiced and unvoiced vocal utterances. Variations in the pitch of each voiced vocal utterance  and the virtual frequency of each unvoiced vocal utterance are then utilized to linearly vary the position of a cursor in the computer display system in two axes independently. In a depicted embodiment of the present invention the analysis circuit includes a short delay to ensure that a valid control signal has occurred.  Thereafter, increases or  decreases  in  pitch  or  virtual  frequency  from  an initial value are utilized to initiate movement by the cursor in a positive or negative direction in the two axes.  Cursor motion will persist until pitch or virtual frequency  return  to  an  initial  value  or  until  the utterance  ceases.  In  one  embodiment  of  the  present invention the appearance of the cursor is graphically altered  to  indicate  the presence  of  a valid  control signal.

Title: Floor covering with underneath metallic mesh to prevent stray current from affecting an animal
Inventor: ROY JACQUES
IPC: H05F3/02
Filed: 1992-03-10
Abstract: ABSTRACT OF THE DISCLOSURE              The covering of the invention is installed on  a  concrete  floor  surface  under  an  animal susceptible  to  contact  a  grounded,  electrically conductive structure, stray current flowing through the floor and/or structure.  A metallic mesh is first applied to the floor surface.  Electrically conductive wires are then used to interconnect the metallic mesh and the structure susceptible to be contacted by the animal.   A rubber mat is finally placed over the metallic mesh.   Of course, the urine of the animal and/or   liquid  manure   establish   an   electrical connection between the top surface of the rubber mat and the metallic mesh.  As the interconnected mesh and structure are equipotential, no stray current can flow through the animal when it contacts the structure.

Title: Digital communication system using superposed transmission of high speed and low speed digital signals

IPC: H04J13/00
Filed: 1992-11-25
Abstract: A digital communication system using superposed transmission of high and low speed digital signals capable of transmitting superposed high and low speed digital signals through an identical frequency band efficiently by increasing a simultaneously transmittable number of channels in the low speed digital signals, while achieving the practically reasonable bit error rate performances for both the high speed digital signals and the low speed digital signals. In this system, the low speed digital signals are transmitted in a form of spread spectrum signals and the high speed digital signals are cancelled out from the superposed transmission signals in obtaining the output low speed digital signals by using the phase inverted replica of the high speed digital signals to be combined with the superposed transmission signals, so that it becomes possible to increase a number of channels for the low speed digital signals, while achieving the practically reasonable bit error rate performances for both the high speed digital signals and the low speed digital signals.
