Appl. No.:

11/491024

Assignee:

Cornell Research Foundation, Inc. - Ithaca NY

International Classification:

H02N 1/00
H02N 2/18
H01L 41/08

US Classification:

310309, 310339, 376320

Abstract:

An electrical energy generator with improved efficiency has a base on which is mounted an elastically deformable micromechanical element that has a section that is free to be displaced toward the base. An absorber of radioactively emitted particles is formed on the base or the displaceable section of the deformable element and a source is formed on the other of the displaceable section or the base facing the absorber across a small gap. The radioactive source emits charged particles such as electrons, resulting in a buildup of charge on the absorber, drawing the absorber and source together and storing mechanical energy as the deformable element is bent. When the force between the absorber and the source is sufficient to bring the absorber into effective electrical contact with the source, discharge of the charge between the source and absorber allows the deformable element to spring back, releasing the mechanical energy stored in the element. An electrical generator of improved efficiency includes a first energy source comprising a piezoelectric transducer secured to the deformable element to convert the released mechanical energy to electrical energy. A second energy source comprises a betavoltaic cell carried on the deformable element or electron collector cantilever beam to provide a direct current (DC) power output that can be added to the piezo-electric circuit's alternating current (AC) power output, such that there is a continuous power output that can be used to provide power to electronic circuits.

International Classification:

G04F 5/14
G06F 1/04

US Classification:

25037011, 368155, 368156

Abstract:

A signal source for use as a frequency source or time keeping signal source includes a radioactive emission source generating a substantially periodic signal corresponding to a radioactive material's disintegration rate. A radioactive emission detector generates a radioactive emission detection signal and, to stabilize the detected periodic signal, a dead time controlling attenuator blanks or shuts off the radioactive emission detection signal for a selected dead time interval in response to each detected radioactive emission (i. e. , a detected signal pulse or signal component) generated by the source. The dead time controlling attenuator output provides a long-term and short-term a stable periodic signal.

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.
