Title: Performance monitoring for loops
Inventor: GUPTA DEV V
IPC: H04L1/24
Filed: 1994-03-03
Abstract: PERFORMANCE MONITORING FOR LOOPS               Abstract of the Disclosure Loop Performance Monitoring (LPM) for DDS loops is described.  Even though DDS loops have Intentional Bipolar Violations (BPVs), a Loop Coding Violations (LCVs) detection strategy based on further processing of BPVs is described.  By monitoring LCVs a local loop terminating device can determine Bit Error Rate (BER).     A system is described by which an Office Channel Unit (OCU) can process LCV information to determine signal quality of the signal over the incoming local loop.  If the signal quality falls below a certain threshold, the OCU can cut the loop off from the DDS circuit and send control codes into the network.     A system is also described where a Network Interface Unit (NIU) with the LPM system communicates incoming LCV information to the OCU using low speed signalling over the simplex path between the transmit and receive pairs.  The OCU monitors incoming LCVs as well, and thus has the information necessary to determine bi-directional BER performance.

The laser beam is of sufficient energy to destroy the sensory organ and incapacitate the pest.
Patent CA-2139284-A1 (CA)
Title: Automation of Plasma Sequestration
Inventor: ANTWILER G DELBERT
IPC: A61M1/02
Filed: 1994-12-29
Abstract: A plasma sequestration system having a volume control system is provided.   When a calculated volume of whole blood has been processed, the system switches from a fill to an empty cycle.  The termination point is calculated in advance, based on the desired composition of the collected plasma, thus improving process control and product uniformity.   The system is automated or partially automated using an optical sensor or marker to monitor the volume of packed red blood cells.  When the red cells reach the marker or sensor,  a  signal  is  sent  to  the  control  system which  then calculates the required fill volume.  Processing continues until the calculated fill volume is reached, at which time the system automatically stops the collection cycle.  The system also provides for two speed operation of the centrifuge as a safeguard against foaming which may result in aerosol formation and blood trauma. Foaming is reduced by reducing centrifuge speed as the packed red blood cells approach the stationary deflector in the centrifuge bowl.

Title: Power drive unit for hand tools
Inventor: EDMAN BRIAN R
IPC: B25F3/00
Filed: 1995-04-19
Abstract: A  power  drive  unit  for  hand tools such as hand operated screwdrivers  with  a  handle at one end, comprising a relatively large  diameter  cylindrical  drive shaft having an annular chuck assembly  secured at one end provides a relatively large diameter passageway  therethrough.  It  is  located on the upper wall of a casing  having an electric motor and a battery therein, or a cord for  connection  to  an external power source. A ring gear around the cylindrical drive shaft is rotated by a gear assembly powered by  the  electric motor to rotate the cylindrical drive shaft and chuck  together  with  whatever  tool is  received  therein. The location  of  the  cylindrical  drive  shaft  and  annular  chuck assembly provides a clear and unobstructed pathway both forwardly and  rearwardly  of  the passageway therethrough. A hand operated screwdriver, for example has its working end inserted through the rearward facing end of the cylindrical passageway and out through the  forward  facing  end  to  a  desired working  position. The opposite  end  of the screwdriver having a handle thereon extends rearwardly  of  the cylindrical drive shaft with enough clear and unobstructed  space to utilize a hand operated screwdriver of any length.  The  chuck  is  then  tightened down on the shank of the screwdriver.  The  motor  is energized to drive the gear assembly and  thus  rotate the screwdriver. A lamp is also provided in the casing to illuminate the working area.
Patent CA-2148105-A1 (CA)
Title: Method and apparatus for authentication of client server communication
Inventor: KINGDON KEVIN
IPC: G06F21/00
Filed: 1993-11-02
Abstract: The present invention provides a method and apparatus for message packet authentication to prevent the forging of message packets. After a message packet is created, a secret session key is preappended to the message, and a message digesting algorithm is executed on the altered message to create a message digest. A portion of the message digest, referred to as the signature, is then appended to the actual message when it is sent over the wire. The receiving station strips the signature from the message, preappends the same secret session key and creates its own message digest. The signature of the digest created by the receiving station is compared to the signature of the digest appended by the sending station. If there is a match, an authentic message is assumed. If there is no match, the message is considered as invalid and discarded. An advantage of the present invention is that the session key is never transmitted over the wire. The receiving station (server) already has the key and uses the key along with the message data to recalculate the message digest upon receiving the packet. The shared secret key (session key) is generated during initiation of the NCP session. In addition, cumulative state information is maintained by both the sending station and the receiving station. This state information is also used to authenticate messages.
