20090038832 | Device and method of forming electrical path with carbon nanotubes - Carbon nanotubes are dispersed in a curable polymer matrix to form a dispersion. When electrical energy is applied to the dispersion, the carbon nanotubes become oriented to form an electrical path. The polymer matrix is cured to fix the electrical path. | 02-12-2009 |
20100094681 | System and Method for Electronically Assisting a Customer at a Product Retail Location - A method is disclosed for electronically assisting a customer through a buying cycle at a product retail location having a product oriented display. The method includes sensing an amount of time the customer is interested in the display. Another operation is determining the customer's stage in a product buying cycle based on the amount of time the customer is interested in the display and displaying product detail based on the customer's stage in the buying cycle. The display can be changed to a subsequent stage in the buying cycle having more time and interaction between the customer and the display. | 04-15-2010 |
