摘要:
The invention provides a purchase sequence browser (PuSB), i.e. a graphical user interface (GUI) that facilitates insight discovery and exploration of product affinities across time, generated by a purchase sequence analysis of a retailer's transaction data. A purchase sequence browser allows the user to browse the most significant product phrases discovered by an exhaustive search of the product affinities across time; explore the retail grammar to create both forward and backward phrase trees or alternate purchase paths starting from, or ending in, a product; generate consistent purchase sequences given some constraints on the products and their order; and profile the value of a product across time with regard to other products fixed in time.

摘要:
Some embodiments provide a method for identifying an event for a particular category. The method classifies several documents as relevant to several different categories. The method identifies a number of documents relevant to the particular category for a current time period and a background time period. Based on a comparison of the number of documents from the current time period relevant to the particular category and the number of documents from the background time period relevant to the particular category, the method identifies an event for the category for the current time period. Some embodiments calculated a score for the event, and normalize the score based on an average number of documents relevant to each of a set of related categories including the particular category.

A method and system for variable speed fan control for thermal management of a device includes disposing a first temperature sensor proximate a variable speed fan to measure an air temperature of inlet air Tair that cools the device by convection air flow. A controller is configured to compensate for changes in Tair by varying a convection coefficient (h) which is a strong function of air velocity to maintain the product of h*ΔT at a constant value, wherein ΔT is a temperature differential between the device (TAD) minus Tair. Thus, h is varied by varying air velocity by varying a speed of the variable speed fan.

摘要:
A method is provided for image detection. The method includes measuring a temperature of an analog-to-digital (A/D) converter of an imaging system during an imaging scan of an object, and correcting a gain of the A/D converter based on the measured temperature of the A/D converter.
摘要:
A lamp having a lighting source, integral electronics, and a thermal distribution mechanism disposed in a housing. The thermal distribution mechanism may include a variety of insulative, radiative, conductive, and convective heat distribution techniques. For example, the lamp may include a thermal shield between the lighting source and the integral electronics. The lamp also may have a forced convection mechanism, such as an air-moving device, disposed adjacent the integral electronics. A heat pipe, a heat sink, or another conductive heat transfer member also may be disposed in thermal communication with one or more of the integral electronics. For example, the integral electronics may be mounted to a thermally conductive board. The housing itself also may be thermally conductive to conductively spread the heat and convect/radiate the heat away from the lamp.
