Abstract: The present invention extends to methods, systems, and computer program products for implementing an auto ship program that adjusts the quantity of goods shipped based on the consumer's usage of the goods. In some embodiments, the auto ship program of the present invention receives consumer notifications indicating that a unit of a shipment has been opened or finished. The program employs the notifications to determine a rate at which the consumer is using units of the goods. If the rate at which the consumer is using the units differs from the rate at which the units are being shipped, the program can suggest or automatically make adjustments to the shipment rate. These adjustments can include modifying the number of units that are shipped in one or more future shipments or changing when one or more future shipments will be sent.

Abstract: Apparatus for performing Raman analysis may include a laser source module, a beam delivery and signal collection module, a spectrum analysis module, and a digital signal processing module. The laser source module delivers a laser beam to the beam delivery and signal collection module. The beam delivery and signal collection module delivers the laser source beam to a sample, collects Raman scattered light scattered from the sample, and delivers the collected Raman scattered light to the spectrum analysis module. The spectrum analysis module demultiplexes the Raman scattered light into discrete Raman bands of interest, detects the presence of signal energy in each of the Raman bands, and produces a digital signal that is representative of the signal energy present in each of the Raman bands. The digital signal processing module is adapted to perform a Raman analysis of the sample.
