Title: Personal computer data transfer control
Inventor: KEENER DON STEVEN
IPC: G06F13/28
Filed: 1992-04-14
Granted: 1996-01-02
Abstract: This  invention  relates  to  personal  computers,  and  more particularly to a personal computer using a small computer systems interface (SCSI) controller coupled directly to the local  processor  bus  for  controlling  data  transfer  with storage memory devices such as  fixed or removable media electromagnetic storage devices.  The personal computer has a  high  speed  local  processor  data  bus  and  a  storage controller coupled directly to said local processor bus for regulating communications between a processor and storage memory devices.   The storage controller has at least one counter for tracking at least one of address and count data for  blocks  of  data  being  transferred and  capable  of signalling through the local processor bus the state of the counter,  and  a  bi-stable  device  interposed  between  the counter and the local processor bus for enabling delivery to the local processor bus of data representing an initial state of the counter at the beginning of a transfer of blocks of data and for continuing  delivery of initial state data throughout a transfer of blocks of data.  The counter and  bi-stable  device  cooperate  for  permitting  one  of incrementing and decrementing of the counter during transfer of blocks of data while avoiding changes in counter state data delivered to the local processor bus during transfer of blocks of data.

Title: Dynamic channel assignment in a communication system
Inventor: BRUCKERT EUGENE J
IPC: H04L12/56
Filed: 1992-12-01
Granted: 1999-08-10
Abstract: A communication system dynamically assigns channels to a subscriber unit so as to, inter alia, mitigate the effects of co-channel interference in the system. The communication system has a plurality of base-stations (111, 112, 115, 118) receiving the transmission of a subscriber unit (120, 100, 121) desiring service. Upon receipt of the subscriber unit's transmission, each base-station determines a signal quality value, which it then reports to a system controller (210). The system controller determines the best signal quality value reported and assigns a channel o the base-station which reported the best signal quality value. The chosen base-station transmits to the subscriber unit on an assigned channel to establish communication. The assigned channel transmitted by the chosen base-station need not be associated with the channel the subscriber transmits on. In fact, either channel may be any one of the channels allocated for use by the communication system.
