Title: Signal selection by majority comparison
Inventor: BOCCI PAUL M
IPC: G06F11/00
Filed: 1986-10-21
Granted: 1992-05-12
Abstract: SIGNAL SELECTION BY MAJORITY COMPARISON     Abstract A signal selection system is disclosed wherein a plurality of received digital signals are combined to form a majority signal.  Each of the received digital signals is compared to the majority  signal to estimate the bit-error-rate (BER) of each received signal.  If the difference between the highest and lowest BER is less than a predetermined threshold, the majority signal is selected for reception.  Conversely, if the BER difference is greater than the predetermined threshold, the received digital signal with the lowest BER is selected for reception.  Thus, the signal with the lowest BER is selected to provide the best possible communications.

Abstract: ABSTRACT OF THE DISCLOSURE    Herein disclosed is a center differential for a four-wheel drive vehicle, which comprises three mem-bers, i.e.: an input member connected for rotations to the output shaft of a transmission; a first output member for transmitting the rotations of the input member to a rear wheel output shaft; and a second output member for transmitting the rotations of the input member to a front wheel output shaft.  Further comprised are frictional engaging means interposed between any two of those three members, and applying force transforming means for generating a force to engage the frictional engaging means on the basis of a tangential force which is generated relatively between any of the three members.  Thus, when the tangential force is generated as a torque is transmitted among the three members, an axial force is generated as a compo-nent of the tangential force to increase the engaging force of the frictional engaging means so that a dif-ferential lock is established to automatically adjust the torque distribution ratio between the rear and front wheels to a proper value.

Title: Regulation of atmospheric conditions within a confined space

Granted: 1991-04-16
Abstract: ABSTRACT OF THE DISCLOSURE            An improved system for maintaining atmospheric conditions within prescribed parameters throughout the interior of a building.  The building interior is essentially an enclosed system and sufficient outside air is admitted through air handling units to continuously maintain the interior of the building under a slight positive pressure throughout.  Controllable vents are provided at strategic locations around the perimeter of the building, and sensing units are located throughout the building to continuously monitor atmospheric conditions such as temperature, humidity, and the level of particulates and pollutants.  The sensing units or monitoring stations are periodically polled by a central computer, with signals from each station providing an indication of atmospheric conditions at that station.  The signals representing existing atmospheric conditions are compared with stored data indicative of prescribed parameters for desired atmospheric conditions at the stations.  Signals are generated in response to noted deviations from the prescribed parameters, and the signals are utilized to regulate the controllable vents and air handling units so as to modify the incoming air or cause air to be discharged through appropriate vents in the area of the monitoring station until atmospheric conditions again fall within the prescribed parameters.  Air is thus delivered from the air handling units to specified areas in a controlled manner without the use of ductwork.
