Title: Mechanically actuated, hydraulically deactuated brake system
IPC: B60T13/22
Filed: 1988-03-07
Abstract: A vehicle brake system includes a check valve (24) 
having an input port coupled to a fluid pump outlet (14) and 
an output port coupled to hydraulically deactuated spring 
brakes (50) through brake lines. A pilot check valve (30) has a 
pilot port, an inlet port coupled to the input port of 
the check valve (24) and a return port coupled to the fluid 
reservoir (12). The pilot port is coupled to the output 
port of the check valve so the pilot check valve opens 
only when the output port is pressurized. This allows 
hydraulic fluid to flow from the pump (6), through the pilot 
check valve (30) and to the reservoir. To set the brakes 
when stopped or in emergency situations the operator 
actuates a valve (72) which dumps the fluid in the brake 
lines into the reservoir. A second pilot check valve 
has its pilot port connected to a brake pedal actuated 
master cylinder, its inlet connected to the brake line 
and its outlet connected to the reservoir. Pressing on 
the brake pedal connects the brake line to the reservoir 
through a variable restriction so to allow the spring 
brakes to be applied in the modulated manner of service 
brakes.

Patent EP-0343768-A3 (EP)
Title: Microcomputer system incorporating a cache subsystem using posted writes
IPC: G06F12/08
Filed: 1989-03-03
Abstract: A microcomputer system includes a microprocessor, a cache memroy, and a 
cache controller all coupled to a local bus. The local bus is coupled to 
a sytem bus, connecting the remaining system components, through latches. 
When writing data, the microcomputer can perform a posted write to a unit 
on the system bus by writing the data into the latches and then, on 
receipt of a ready signal from the cache controller, continuing its 
operations without waiting for the data to pas to its destination. A 
problem arises if the data is posted to a unit with a data width less than 
that of the microprocessor. In this case, the data should be sent in 
multiple cycles, but the read signal is generated before the data width of 
the unit is known and the microprocessor then continues its operations and 
can not, therefore, transmit the data correctly. To solve this problem, a 
logic unit is added to monitor the ready signal and the output of a 
decoder which detects non-cacheable addresses (which are of data width 
different from the microprocessor data width). If a non-cacheable address 
is detected, the read signal from the cache controller through the logic 
unit is withheld from the microprocessor, which now waits to continue 
processing beyond the write until a ready signal is received from the 
addressed unit on the system bus.
