  • Patent number: 9853523
    Abstract: An electric wheel motor cooling system includes first and second electric wheel motors and gear reducers which use hydraulic fluid for cooling and lubrication. Each of the electric wheel motor housings includes a sump and a scavenge pump for return of hydraulic fluid to the hydraulic fluid reservoir. A remotely located hydraulic pump interconnected with the hydraulic fluid reservoir supplies and powers first and second locally located hydraulic motors which supply the electric motors and gears with an equal flow of lubricating and cooling oil. The first and second hydraulic motors, in turn, drive a common output shaft which, in turn, drives first and second scavenge pumps. The first and second scavenge pumps have a higher fluid flow rate than the hydraulic motors ensuring that oil is removed from the first and second electric wheel motor housings thus eliminating any churning losses of the motors or gears.

  • Patent number: 7117430
    Abstract: An error checker identifies spreadsheet errors by traversing a spreadsheet cell-by-cell and comparing each cell's contents to a list of error rules. When a cell's contents satisfy an error rules, then the cell is identified as containing a potential spreadsheet error. The error checker identifies potential spreadsheet errors and marks the cells containing the potential errors with an error indicator. A drop-down menu is provided that includes an element identifying the error rule that was invoked by the cell's contents and may include one or more recommended actions to resolve the identified error.

  • Publication number: 20020161799
    Abstract: An error checker identifies spreadsheet errors by traversing a spreadsheet cell-by-cell and comparing each cell's contents to a list of error rules. When a cell's contents satisfy an error rule, then the cell is identified as containing a potential spreadsheet error. The error checker operates in both background and foreground modes. In background mode, the error checker identifies potential spreadsheet errors and marks the cells containing the potential errors with an error indicator. A drop-down menu is provided that includes an element identifying the error rule that was invoked by the cell's contents and may include one or more recommended actions to resolve the identified error. The menu can also include selections for referencing a help facility for more information about the identified error, ignoring the error, accessing the cell to edit the cell's contents, and accessing a debugging utility for evaluating and modifying a spreadsheet formula.
