Patent CA-2076809-A1 (CA)
Inventor: ORESICK CARL F
IPC: G03G15/02
Filed: 1992-08-25
Abstract: An apparatus and method for maintaining a constant voltage potential on a photoconductive member within an electrophotographic printing system comprises and utilizes, respectively, a charging device, a voltage monitor and a controller. The charging device produces a voltage potential on a photoconductive member within the electrophotographic printing system. The voltage monitor measures the voltage on the photoconductive member and generates a voltage measured signal. The controller, responsive to the voltage measure signal, stores a target voltage value and computes the difference of the measured voltage signal and the target voltage value to obtain a voltage error for a prior print job. The controller computes a predicted control signal for the corresponding cycle of the next successive print job as a function of the voltage error and regulates the charging device for the corresponding cycle of the next successive print job as a function of the predicted control signal.

Filed: 1993-05-21
Abstract: ABSTRACT OF THE DISCLOSURE A machine for sharpening skates that can be operated by an individual through a coin-operated or credit card operated input, permits a person that wants skates sharpened to place the skate into the machine and have it automatically sharpened in a manner that is selected by the operator. The operator places a skate into a support and the machine centers and clamps the blade. The machine includes a grinding wheel that is dressed before each sharpening operation, to provide a wheel surface that gives the proper shape to the bottom surface of the ice skate blade, and after dressing, a skate held in the clamp is moved across the wheel so the bottom edge surface of the ice skate is sharpened uniformly along its operable length. The machine includes inputs so that either figure skates or hockey-style skates can be sharpened, and positive clamps that hold the blade directly during its sharpening operation. An access door for operators to put in skates is also interlocked so that operation cannotcommence until the door is fully closed. The various operations are controlled primarily with fluid-pressure actuators, and the skate itself is centered in itsposition on the cradle support prior to clamping so that it is properly positioned for complete grinding across the bottom surface.

Title: Congestion control in high speed networks
Inventor: COLE ROBERT G
IPC: H04L12/56
Filed: 1993-06-25
Abstract: Congestion control is implemented at the resources that actually suffer from congestion and, moreover the congestion control is performed within the network as well as at its access points. In a particular embodiment, congestion control is continuously performed at each resource. Use of each resource is controlled according to a head-of the-line weighted round-robin service discipline thereby assuring fairness and full use of bandwidth for all active channels. Also, in order to control conditions of congestion, the queue of data elements waiting for service at each resource is regulated by a global congestion indicator for the entire queue. The data elements of each channel that are waiting for service are further regulated in response to specific local congestion indicators that are individualized for each channel. The global and local congestion indicators are used to guarantee predetermined levels of service for each channel. The values employed for tie head-of the-line weighted round-robin service discipline are developed as a function of at least the contracted-for bandwidth for each channel. The developed values are replicated for each resource subject to congestion control.

IPC: H04L12/56
Filed: 1993-06-30
Abstract: A method of  sending an electronic message from a source station  through  a  network  of  switches  and  links  to  a destination station. An electronic message is sequentially sent to each of a series of switches. Each switch reads a route  signal  in the message  and sends the message to  a switch or a station having an input port connected to an output  port  identified  by  the  route  signal.  The  route signals are generated by storing a weight for each switch link in the network.  Candidate paths  through the  switch network starting at the source station and ending at initial candidate   destinations   are   identified.   Each   initial candidate destination has an input port directly connected to an output port of a switch having an input port directly connected to the source station.  If one or more candidate destinations are the destination station,  a candidate path ending at the destination station is selected, and a series of route  signals corresponding to the  selected candidate path  is  generated.  If  no  candidate  destination  is  the destination station,  extended candidate paths are formed. Each extended candidate path has a path weight comprising the weights of switch links along the candidate path. If one or more extended candidate destinations are the destination station, a candidate path ending at the destination station and having a path weight better than or equal to the path weight  of  each  other  candidate  path  ending  at  the destination station is selected.  Otherwise,  the candidate paths are again extended.
