Abstract:

A system and method for virtual canvas generation, product catalog searching, and result presentation. A user that searches multiple virtual catalogs can be provided with search results in a highly useful format. The search results can include a ranked list of product catalogs along with a further display of a non-sequential set of catalog page images that include product information. Virtual canvases can also be created that are customized based on various criteria, such as the characteristics of the user device. The virtual canvas can also include supplemental data that is associated with the search result set.

International Classification:

G01N 33/00
G01N 27/00

Abstract:

A sensor includes a first sensing element electronically sensitive to an analyte and to an interfering stimulus. The first sensing element provides a first electrical signal in response to a presence of the analyte and/or the interfering stimulus. The sensor also includes a second sensing element electronically sensitive to the analyte and to the interfering stimulus. The second sensing element provides a second electrical signal in response to the presence of the analyte and/or the interfering stimulus. A conductive link electrically connects the first sensing mechanism and the second sensing mechanism. An electrical property is measured within the sensor that is indicative of a concentration of the analyte based on the first electrical signal and the second electrical signal.

International Classification:

G01N 27/414
G01N 33/00
H01L 27/28
H01L 27/098

Abstract:

A ratiometric vapor sensor is described that includes a first sensor and a second sensor. The first sensor includes a first semiconductor component comprising a vapor-sensitive semiconducting organic compound, while the second sensor includes a second semiconductor component comprising a modified vapor-sensitive semiconducting organic compound including a modifying organic group. The ratiometric vapor sensor can be used to detect the presence of a vapor such as nitrogen dioxide, and determine the concentration of the vapor by comparing the outputs of electrodes connected to the first and second sensor.
