An inspection system for verifying package contents comprises a spectrometer having an input for receiving light energy and a light energy aggregator. The light energy aggregator comprises a light energy input terminal, a light energy output terminal, where the light energy output terminal is coupled to the spectrometer input, and at least two sample probes coupled to the light energy input terminal. Each of the sample probes is configured to direct light energy from a source to the light energy input terminal.

A system and method for determining bias in a spectrometer is described. One embodiment includes a method for determining bias in a spectrometer system, the method comprising over-scanning a grating in a near-zero-response wavelength range; and determining a bias based on the over-scanning. This methodology allows for over-scanning a grating in a near-zero-response wavelength range as a substitute for using shutters or other mechanisms to block light from entering a detector in the system.

An apparatus applies dressing fluid to a bowling lane surface in a discrete pattern laterally across a plurality of zones on the bowling lane. A carriage, for movement along a bowling lane, has an applicator mounted thereon for applying the dressing fluid to the bowling lane surface. Dressing fluid is supplied from a reservoir by a plurality of pulse valves which supply the dressing fluid to a plurality of fluid dispersion chambers, each having an inlet connected to one of the pulse valves and having an outlet positioned to apply dressing fluid to the applicator. The outlet has a width equal to the width of one of the zones. A controller is provided for selectively activating each of the pulse valves to discharge a discrete amount of fluid dressing into each dispersion chamber. Each zone may be the width of one board across the bowling alley so that different discrete amounts of oil can be applied to each board. A method is provided to supply discrete amounts of bowling lane dressing to each of a plurality of zones wherein each zone is one board width or portion of a board width.

An apparatus applies dressing fluid to a bowling lane surface in a discrete pattern laterally across a plurality of zones on the bowling lane. A carriage, for movement along a bowling lane, has an applicator mounted thereon for applying the dressing fluid to the bowling lane surface. Dressing fluid is supplied from a reservoir by means off a plurality of pulse valves which supply the dressing fluid to a plurality of fluid dispersion chambers, each having an inlet connected to one of the pulse valves and having an outlet positioned to apply dressing fluid to the applicator. The outlet has a width equal to the width of one of the zones. A controller is provided for selectively activating each of the pulse valves to discharge a discrete amount of fluid dressing into each dispersion chamber.

An apparatus applies dressing fluid to a bowling lane surface in a desired lane dressing pattern laterally across a plurality of zones on the bowling lane and longitudinally along a predetermined length of each of the zones. Each zone may be the width or a selected fractional width of one board across the bowling lane so that different discrete amounts of lane dressing can be applied to each board along a predetermined length. The apparatus includes a plurality of metering devices which supply lane dressing to corresponding lane dressing dispersion units which in turn supply lane dressing directly to an applicator. The applicator applies the lane dressing to the bowling lane according to the desired lane dressing pattern. A method is provided to supply discrete amounts of bowling lane dressing at desired incremental locations laterally across and longitudinally along a bowling lane. Further, a method is provided for calibration of the apparatus of this invention in order to achieve application of complex lane dressing patterns to the bowling lane.
