Title: Electronic circuit for generating error detection codes for digital signals
Inventor: MARCHISIO MAURO
IPC: H03M13/15
Filed: 1991-02-27
Granted: 1998-05-19
Abstract: An electronic circuit, for generating error detection codes from digital signals organized into serial data blocks, in which the error code is derived from the coefficients of a remainder polynomial obtained from the division by a suitable divisor polynomial of a dividend polynomial whose coefficients are the bits of each serial block, is implemented by feedback through adders within shift register.  A reset of the register necessary at the beginning of each serial data block and the loading of a first data bit of the block are both performed in a single clock interval, by using flip-flops to form the register which have alternative inputs one of which is used during reception of the first bit of a block to handle that bit and place the remainder of the register in a defined condition, and the other of which is used during processing of the remaining bits.

Title: Antilock brake system and method incorporating a pressure feedback
Inventor: PECK DAVID E
IPC: B60T13/66
Filed: 1991-03-21
Granted: 1997-03-04
Abstract: An air brake system for a truck includes a treadle valve, a pilot control isolation valve, an exhaust valve, a relay valve,  an air pressure transducer,  a wheel speed sensor, an electronic control unit (ECU) and an air brake chamber associated with a brake actuator.  In heavy braking operations, the pilot system pressure rise rate is monitored and restricted by modulation of the pilot control isolation valve.  During heavy braking operations, if braking of the vehicle wheel results  in a wheel velocity change which exceeds a predetermined deceleration threshold, the pressure rise rate is further restricted in attempt to "creep" up on the brake system pressure at which the lock condition is expected to occur.  At another predetermined deceleration threshold, the brake system pressure is vented.  The brake system pressure decreases resulting in a reduction in the applied brake force thereby permitting the vehicle wheel to roll back up to speed.  The roll up rate is a function of the coefficient of friction of the road surface, the loading of the respective vehicle wheel and residual brake force remaining in the system.   Empirical testing has revealed that a close approximation of the friction force available for stopping the vehicle may be made by use of the pilot system pressure when the vehicle wheel  reaches minimum velocity and the time required to reach a certain wheel velocity greater than the minimum velocity.  The friction force may be used to control parameters of operation of the antilock brake system during subsequent antilock cycles.     For example, subsequent cycle brake system pressure rise rate is restricted by values determined from the friction force noted from previous cycles.  Also, the deceleration condition at which the brake system pressure is exhausted and the pressure to which the system is exhausted are determined  from  the  calculation  of  the  friction  force available during previous cycles.

Title: Autonomous registration overload control for cellular mobile radio systems
Inventor: COSENTINO PHYLLIS
IPC: H04W28/02
Filed: 1991-06-04
Granted: 1995-08-01
Abstract: Registration signal channel overloads occurring due to overly numerous autonomous registration messages initiated by the mobile radiotelephones are averted by monitoring the number of autonomous registrations occurring or requested in aparticular local cellular system and responding in the event of an impending overload by sending messages to specified mobile radiotelephones instructing them not to register at this time. In one implementation disclosed herein the roamer mobile radiotelephones requesting registration within an area covered by a cellular system facing an impending overload are instructed, via an overhead message, not to register. Allowance of registration is not permitted until the overload condition is terminated. In another implementation the period between autonomous registrations is increased until the overload is cleared.

Abstract: The invention relates to a catholic protection system for an above-ground storage tank having a metal bottom, both new and retrofitted bottoms. A leak containing dielectric safety membrane is spaced a short distance below and extends beneath the tank bottom generally parallel thereto forming a narrow envelope. Compacted electrolytic conductor is positioned between the membrane and the tank bottom supporting the tank bottom embedding a horizontally disposed catholic protection anode, the anode being in the form of a matrix or grid of interconnected titanium bars and ribbons. A  reticulate dielectric insulator may be embedded in the electrolytic conductor and positioned directly above the anode and such insulator is operable to keep any portion of the anode from contacting the tank bottom and to maintain a generally uniform spacing between the anode and tank bottom. The ribbons extend transversely of the bars and are spot welded on uniform centers to bars on diameters or major chords of a circular tank bottom. A low profile connection is provided between the bars and power feeds to a rectifier, and for large tank bottoms a multiplicity of such connections strategically spaced are provided. Similarly, a plurality of reference cells both in location and kind may be provided so there are redundant power feeds and reference cells. The anode is constructed by uncoiling, arranging and connecting the bars and ribbons on a compacted layer of electrolytic conductor on the liner. After the conductors are attached and routed to the external rectifier, the insulator may be placed above the anode grid.  Further compacted electrolytic conductor fills the openings in the insulator.
