Patent number: 6226771Abstract: An error detection generator calculates error detection data for insertion into encapsulated frames. The error detection generator is configured to calculate multiple error detection values and insert them into corresponding fields of the encapsulated frames. The error detection generator includes a controller, three cyclic redundancy check (CRC) engines and at least one multiplexer. Each CRC engine is selectively enabled by the controller to calculate a frame check sequence (FCS) value on a different portion of the frame. Downstream CRC engines also receive the outputs from the upstream CRC engines so that these earlier FCS values may be used during subsequent calculations. The outputs of the CRC engines are also inserted into the appropriate fields of the encapsulated frames by the multiplexer.Type: GrantFiled: December 14, 1998Date of Patent: May 1, 2001Assignee: Cisco Technology, Inc.Inventors: Stephen C.

Patent number: 5849101Abstract: A method of washing objects in a dishwasher having upper and lower spray arms within a wash chamber and a sump filter. Wash liquid entering a sump from the wash chamber to be recirculated by a pump is filtered the filter to prevent soils from entering the sump and being recirculated. When the lower spray arm is operating, wash liquid is directly sprayed onto the filter from a clean-out nozzle on the lower spray arm to clean soils off the filter and prevent the filter from clogging. During a pre-wash cycle and at least one pre-rinse cycle, wash liquid is continuously sprayed from only the lower spray arm to prevent the filter from clogging when heavy soils are removed. During a wash cycle and at least one rinse cycle, wash liquid is alternately sprayed from the lower spray arm and the upper spray arm when the heavy soils have already been removed and it is less likely the filter will become clogged.Type: GrantFiled: August 5, 1996Date of Patent: December 15, 1998Assignee: White Consolidated Industries, Inc.Inventors: James M. Edwards, John E. Dries

Patent number: 5762080Abstract: A washer for washing objects with liquid. The washer includes a wash chamber adapted for holding objects to be washed. The sump has a pump chamber and a collection chamber, both of which are adapted to hold liquid from the wash chamber. A recirculation pump is operable to move liquid from the pump chamber to the wash chamber. A drain pump is operable to move liquid from the pump chamber and the collection chamber to a drain. A rotatable blade is disposed in the collection chamber and is adapted to mince particles therein. A controller is provided for controlling the operation of the recirculation pump and the drain pump. The controller is operable to turn the drain pump on and off during a wash phase in order to move particles from the collection chamber to the drain. The controller is also operable to turn the drain pump on at the end of the wash phase in order to initiate a drain phase wherein the drain pump drains the sump of liquid.Type: GrantFiled: January 24, 1997Date of Patent: June 9, 1998Assignee: White Consolidated Industries, Inc.Inventors: James M.

Patent number: 5628334Abstract: A dishwasher sump is divided into a collection chamber and a pump chamber by a filter. Food particles collect in the collection chamber while filtered wash liquid collects in the pump chamber. A pump has an inlet located in the pump chamber. The filtered wash liquid is recycled and sprayed on objects in the dishwasher by the pump. The impeller is driven by a shaft extending through the collection chamber and a wall separates the pump chamber from the collection chamber. Food particles in the collection chamber are minced by a rotating blade on the pump shaft. Balancing vanes on a rear face of the impeller prevent food particles and dirty water from flowing into the filtered liquid from the collection chamber. At the end of a wash cycle, the minced food particles are pumped to a drain with the wash liquid.Type: GrantFiled: April 25, 1995Date of Patent: May 13, 1997Assignee: White Consolidated Industries, Inc.Inventors: James M.
