Abstract:

An inventory control system includes an inventory control probe, inventory control module, a docking station, a collar clip, and an inventory control collar used on a storage container. The inventory control collar includes a first conductive ring exposed on the top of the collar electrically connected to a memory and a second conductive ring exposed on the top of the collar and electrically connected to the memory. The inventory control probe includes a probe tip and a first pair of contact pins disposed on the probe tip at a predetermined distance apart such that the contacts concurrently contact the conductive rings of the inventory control collar. A probe body housing is connected at a first end to the probe tip, and a pair of data transfer terminal contacts are disposed on a bottom portion of the probe body housing. A handle is connected at a second end to the probe body housing. The inventory control module includes a control module housing, a pair of data transfer terminal contacts disposed on a bottom portion of the control module housing for engaging the pair of data transfer terminal contacts disposed on the docking station housing, a microprocessor, and a memory.

Abstract:

In a system having a PCI bus, an additional memory attached to the bus to allow a higher speed of data transfer for a number of copies from the computer to a number of devices. The additional memory has a number of DMA channels, each associated with an I/O device. One copy of the data required by an I/O device is transferred to the memory at normal computer FIFO speed. Thereafter, multiple copies of that data can be transferred to the I/O device from the memory at the higher data bus speed.
