Title: Brake control system
IPC: B60T13/58
Filed: 1985-02-11
Abstract: o A brake control system for a multiple unit train of mixed motor cars and trailer cars - of the type usually to be found operating as metro or mass transit trains - and in which the motor cars have dynamic brakes operation of which is blended with, but given preference over, the friction brakes of all units. A brake demand signal calling for a given level of train retardation is weighted on each vehicle, according to the load of the vehicle, and the level of dynamic braking effort invoked on each motor car is limited in accordance with a maximum adhesion level calculated in proportion to the measured load of that car. In a modified arrangement the adhesion level is calculated in accordance with the load of the lightest loaded motor car. Signals representing the amount of dynamic brake effort achieved by each motor car is supplied to a trailer car and subtracted from the load weighted braking effort for the trailer car and the result used to actuate the friction brakes of the trailer.

Title: Apparatus providing data backup upon power failure in a micro-computer controlled television receiver
IPC: H04N5/44
Filed: 1986-08-22
Abstract: The apparatus for use in a television receiver of the kind controlled by a micro-computer (10) is intended for the situation in which power failures occur and specifically where instantaneous power failures occur and shortly thereafter the power is recovered, in which it is determined whether or not the time display data stored in a memory of the micro-computer is correct and, if so, such data is continued to be refreshed and is used for the time display, whereby a so-called backup circuit is simplified in construction, and even eliminated in some cases. The main television receiver control data are stored in a nonvolatile memory (24) when a power interruption occurs, but are only used to refresh the random access memory (13) of the micro-computer (10) in those instances where the power outage exists for a period of time long enough to erase the time display data retained in the random access memory (13), a condition that is determined by checking such time display data each time it is necessary to reset the central processing unit (11) of the micro-computer (10) in view of a drop in line voltage.

Patent EP-0272479-A3 (EP)
IPC: H03K5/08
Filed: 1987-11-24
Abstract: A differential comparator (16) includes a matched 
pair of transistors (Q1, Q2) having emitters coupled to a 
current source (22) through a pair of emitter-degener­
ation resistors (R1, R2) and having collectors coupled to a 
voltage source through a pair of load resistors (R3, R4) 
such that a differential input voltage (Vbd) applied 
across the transistor bases produces an amplified 
differential output voltage (Vdo) across the transistor 
collectors. The emitter-degeneration resistors (R1, R2) are 
sized so that a differential input current (Ibd) produced 
in the bases of the amplifier transistors (Q1, Q2) is sub­
stantially constant over a range of differential 
input voltage (Vbd) including the range for which the 
amplifier transistors (Q1, Q2)  remain active when the input 
voltage (Vin) varies with constant slew rate, thereby 
minimizing variation in input capacitance with 
respect to input voltage (Vin). This in turn minimizes 
variation in time delay between the comparator 
differential input and output voltages with respect 
to input voltage slew rate.

Patent EP-0261876-A3 (EP)
IPC: H04B10/142
Filed: 1987-09-17
Abstract: Stimulated Brillouin scattering of optical signals is employed to provide 
narrowband tunable reception of a selected optical signal from a plurality of 
optical signals by using an optical pump source (162) at the receiver (16-i) for 
launching an optical signal (ν p,i )propagating in a direction opposite to the 
plurality of optical signals (ν l ...ν k )to provide stimulated Brillouin amplification 
of the selected optical signal (ν l )at the receiver. The frequency for the optical 
pump source is separated from the frequency for the selected optical signal by 
the appropriate Brillouin-Stokes shift for the transmission medium. By tuning 
the frequency of the optical pump source at the receiver in increments equal to 
the frequency separation of adjacent optical signals in the plurality of optical 
signals, it is possible to amplify any single desired optical signal from a plurality 
of adjacent optical signals (FIG. 1).

IPC: G11B20/14
Filed: 1987-10-23
Abstract: In a data processing system having an 
associated magnetic storage device, a controller is 
disclosed that permits storage capacity of the 
magnetic storage device to be substantially increased 
without altering either the data processing system 
control signals or the portion of the magnetic 
storage apparatus physically storing and/or 
retrieving the data signals on the magnetic media. 
The storage capacity is increased by using an 
encoding scheme that, although not substantially 
changing the density of flux reversals on the 
magnetic media, stores approximately twice the 
information. Apparatus is disclosed for improving 
the detection and decoding of the information stored 
on the magnetic media. The technique for increasing 
the information density, while particularly relevant 
to the magnetic hard disk systems used with personal 
computers because of the capability of increased 
information storage by altering only the magnetic 
hard disk controller, can also be used with other 
information storage systems such as optical storage 
systems.
