Title: Memory card architecture and interface
IPC: G06F11/10
Filed: 1989-05-17
Abstract: A "smart" memory card architecture and 
interface provides significantly increased 
performance, in part, by using fast access dynamic 
random access memory (DRAM) technologies which 
allows up to 8-byte data transfers from the memory 
card every 27ns after the initial access. The 27ns 
transfer rate includes the time required for error 
correction code (ECC), parity generation, and other 
reliability functions. Only two complementary 
metal oxide semiconductor (CMOS) integrated circuit 
(IC) logic chips or modules provide all the 
function required. The simplicity and flexibility 
afforded by the "smart" memory card approach 
provides a means to allow one card interface to be 
used with a broad range of hardware technologies 
and in different systems. The architecture of the 
memory card provides a full range of direct and 
partial store operations in a manner transparent to 
the system.

Patent EP-0349123-A3 (EP)
Title: Multi-processor computer systems having shared memory and private cache memories
IPC: G06F15/16
Filed: 1989-05-30
Abstract: Multi-processor systems are often implemented using a 
common system bus as the communication mechanism between 
CPU, memory, and I/O adapters. It is also common to 
include features on each CPU module, such as cache memory, 
that enhance the performance of the execution of 
instructions in the CPU. Many architectures require that 
the hardware employ a mechanism by which the data in the 
individual CPU cache memories is kept consistent with data 
in main memory and with data in other cache memories. One 
such method involves each CPU monitoring transactions on 
the system bus, and taking appropriate action when a 
transaction appears on the bus which would render data in 
the CPU's cache incoherent. If the CPU uses queues to 
hold records of incoming transaction information until it 
can service them, the bus interface must guarantee that 
the queued items are processed by the cache in the correct 
order. If this is not done, certain types of shared data 
protocols fail to operate correctly. The present 
invention describes a method by which hardware can 
guarantee the serialization of transactions requiring 
service by the CPU cache. The serialization method 
described guarantees that shared memory protocols operate 
correctly.

Title: Dual-purpose rotating brush for vacuum cleaner
IPC: A47L9/04
Filed: 1989-07-13
Abstract: A cylindrical power brush for a vacuum cleaner 
includes two types of bristle tufts (70). One type (70 b ) 
of bristle tuft is short and stiff for contacting and 
agitating a carpeted surface. The other type (70 a ) of 
bristle tuft is longer and softer for contacting a hard 
surface. In addition to the differences in length and 
bristle stiffness, the tufts (70 b ) for the hard surface 
contain substantially fewer bristles, whereby catching 
and rolling of carpet edges is avoided. One embodiment 
alternates types of bristle tufts in a row of bristle 
tufts. Another embodiment employs multiple rows of bristle 
tufts arranged such that a point on a surface being cleaned 
is contacted alternately by the two types of bristle tuft. 
Winding up of thread and hair on the axle of the rotating 
brush is avoided by overlapping annular extensions (190, 
188) on a support wheel (184) and a brush spindle (186). 
The brush support wheel is locked in place in the floor 
tool by a resilient locking tab integrally formed with one 
of the halves of the floor tool.
