Title: Single sideband modulator for translating baseband signals to radio frequency in single stage
Inventor: MORRIS KEITH D
IPC: H03C1/60
Filed: 1992-11-03
Abstract: ABSTRACT           A single sideband modulator provides a means of translating low frequency baseband signals directly to radio frequency in a single stage.  Such modulators, providing suppressed carrier and one or two of the sidebands, facilitates the transmission of intelligence with significantly increased gain over AM transmission. Control signals are continuously generated to keep the local oscillator breakthrough and image sidebands down to an insignificantly low level.  This is achieved by monitoring amplitude of the RF output of the single sideband modulator, and comparing this with the baseband signals.  By adjusting the d.c. offsets at the baseband inputs to the balanced modulators, carrier breakthrough is cancelled.  By adjusting the relative phases of the baseband signals, deviations from the 90° split are compensated.  By changing the amplitude of one of the baseband signals, the level of one of the RF paths is adjusted to achieve amplitude balance.

Patent CA-2089306-A1 (CA)
Inventor: MARTINO MICHAEL J
IPC: G06F21/14
Filed: 1993-02-11
Abstract: A mechanism for an automated system to allow a user of the system to demonstrate his legitimacy by demonstration of secret knowledge.  The mechanism is resistant to compromise by observation of its use.  An array of symbols is presented to the user and the user is required to manipulate several symbols at once until assigned key symbols are manipulated into predetermined states.  Doing so effectively prevents an observer  from determining which  symbols are  the  ones of interest.  For example, pushing a button might cause several symbols in the array to exchange their positions.  The user continues  to  do  this,  having,  perhaps,  to  use  several different buttons,  until a certain subset of the symbols appears in certain locations within the array.   (In this example, the arrangement of this subset of symbols is the user's password or PIN.)   In this process many symbols in the array, in addition to the user's specific symbols, would also have been moved, making it virtually impossible for an observer to identify which symbols and array-positions are pertinent to the user's password or PIN.

Abstract: Methods of and apparatus are provided for placing a cover lifter at a position at which a cover for a load-carrying vehicle (such as a standard gondola car) must be lifted to form a non-load-formed peak.  A web is quickly installed, and need be installed only at the locations at which there is a valley in the load.  The web is placed transversely across the car generally in the horizontal plane of the top of the car.  The web supports the cover lifter which is initially (during placing of the cover over the web and the loaded car) flat and generally in the plane of the top of the car.  After placing the web tightly on the car, and then securely tying the cover to the car over the web, the cover lifter is raised and causes the cover to stretch in a controlled  manner  and  form  a  lifter-peak,   which  is  a non-load-formed peak at just the location at which the load did not form such a load-formed peak, but did form a valley.

Abstract: The invention relates to a method for determining characteristics of the flow of a medium in a channel by measuring the transit time of sound waves which are transmitted between one or more transducers, and determining the characteristics from the measured transit times.      In one embodiment of the method according to the invention, at least two sound waves whose transit time depends on swirl are transmitted along acoustic paths with a different sensitivity to swirl, and a measure of the swirl is determined from the measured transit times.      In another embodiment, at least two sound waves whose transit time depends on the symmetry of the flow profile are transmitted along acoustic paths with a different sensitivity to symmetry, and a measure of the symmetry is determined from the measured transit times.      These embodiments are preferably combined.      If weighting factors are allocated to the values obtained, the individual velocities of the sound waves can be used to calculate the average flow velocity and/or the throughput of the medium. Since allowance is made for possible disturbances of the velocity profile, the accuracy of the calculated variables is good.      The invention also provides for a device, by means of which the method according to the invention can be carried out.
