Abstract: In one preferred implementation, a business rules engine optimizes staffing decisions by accepting as inputs top-down constraint as well as bottom-up constraint rules to dynamically determine short to medium term optimal staffing patterns. The business rules engine of this embodiment optionally utilizes a Holt-Winters algorithm which factors in both seasonal and annualized trend information. In certain embodiments, the business rules engine is able to more accurately estimate necessary minimum staffing based on business constraints at both the strategic and operations levels. For instance, strategic (top-down) factors may include intentional overstaffing of stores during certain time periods or in certain key geographic regions, sales forecasts, aggregate margin enhancement, etc. Operational (bottom-up) factors can, in selected embodiments, include time-to-unload, time-to-stock, product throughput and related factors.

Abstract: Method and apparatus for testing the video subsystem of a PC in a manufacturing environment. Hsync and Vsync signals from a VGA connector of the PC are input to first and second trigger inputs, respectively, of a monostable multivibrator (“MM”) of the test device to drive respective outputs thereof. In particular, the presence of Hsync at the first trigger input triggers the MM to output a positive pulse at a first output thereof; similarly, the presence of Vsync at the second trigger input triggers the MM to output a positive pulse at a second output thereof. Each of the first and second outputs is used to drive an LED, such that the presence of Hsync and/or Vsync results in the illumination of a corresponding LED.
