Appl. No.:

10/117787

Inventors:

Steven Chu - Stanford CA
Vladan Vuletic - Stanford CA

Assignee:

The Board of Trustees of the Leland Stamford Junior University - Stanford CA

International Classification:

F25B 2100

US Classification:

62 31, 62467, 250251

Abstract:

The invention relates to a method and apparatus for cooling multilevel entities such as atoms, ions or molecules as well as entities with no apparent internal structure. Cooling is achieved by coherent scattering, where the frequency of the emitted radiation exceeds the frequency of the illumination radiation. Such coherent scattering is achieved by placing the entities in a resonator containing in which the cavity length and mirror coating are selected to support a resonant radiation. The entities are illuminated with an illumination radiation whose energy is lower than that of the resonant radiation supported by the resonator by a certain detuning energy selected such that coherent scattering of resonant radiation from the entities at a higher frequency than that of the illumination radiation is promoted by the resonator. As a result of the coherent scattering energy is carried away from the entities and they are cooled.

International Classification:

G01F 1/00

US Classification:

73861, 7386105

Abstract:

A device for confining an object to a region proximate to a fluid flow stagnation point includes one or more inlets for carrying the fluid into the region, one or more outlets for carrying the fluid out of the region, and a controller, in fluidic communication with the inlets and outlets, for adjusting the motion of the fluid to produce a stagnation point in the region, thereby confining the object to the region. Applications include, for example, prolonged observation of the object, manipulation of the object, etc. The device optionally may employ a feedback control mechanism, a sensing apparatus (e. g. , for imaging), and a storage medium for storing, and a computer for analyzing and manipulating, data acquired from observing the object. The invention further provides methods of using such a device and system in a number of fields, including biology, chemistry, physics, material science, and medical science.

US Classification:

705 711, 705 742

Abstract:

A system and method for encouraging the exchange of feedback in an enterprise. An example method includes providing one or more user interface controls for configuring a feedback reminder to automatically include predetermined insight pertaining to a potential participant in a future feedback exchange; sending the feedback reminder to a messaging system or application; providing a user option to view content of the feedback reminder; and displaying the feedback reminder in response to user selection of the first user option. Another user option enables selection of particular insight, derived from a talent management system, for inclusion in the feedback reminder. The messaging system may include an email application or an application for displaying a worklist.

International Classification:

G06F019/00

US Classification:

702/117000

Abstract:

Methods of efficiently and accurately heating a semiconductor device in a standard (i.e. room temperature) handler are provided. In one embodiment, an infrared light source can be focused on the device to heat its chip. In another embodiment, the substrate diode in the device can be forward biased to heat the chip. Advantageously, the forward voltage of the substrate diode has a direct relationship with chip temperature. This relationship can be determined based on a characterization of an exemplary device type. Therefore, measuring the forward voltage can provide an accurate derivation of chip temperature. Heating of the device using a focused light source or substrate diode can be done immediately prior to testing, thereby providing an extremely time efficient way to test the device under high temperature conditions.

International Classification:

H04N 7/18

US Classification:

348 79, 348E07085

Abstract:

An embodiment of the present invention is an imaging arrangement that includes imaging optics, a fiducial light source, and a control system. In operation, the imaging optics separate light into first and second tight by wavelength and project the first and second light onto first and second areas within first and second detector regions, respectively. The imaging optics separate fiducial light from the fiducial light source into first and second fiducial light and project the first and second fiducial light onto third and fourth areas within the first and second detector regions, respectively. The control system adjusts alignment of the imaging optics so that the first and second fiducial light projected onto the first and second detector regions maintain relatively constant positions within the first and second detector regions, respectively. Another embodiment of the present invention is a microscope that includes the imaging arrangement.

Abstract:

A system and method for designating or tagging an electronic message, such as an email that includes feedback about an employee's performance. The tagged email can then be automatically embedded within, or otherwise associated with, a performance management document such as a performance review. An example method includes providing a user interface display screen, whereby a user may view contents of an electronic message; providing a first user option, in association with the user interface display screen, to selectively designate the electronic message for a predetermined purpose and providing a signal in response thereto; and associating the electronic message with a document in response to the signal in accordance with a designation of the electronic message. In a specific embodiment, the designation of the electronic message includes a feedback designation, such that the electronic message is designated as a feedback message. The feedback message represents unsolicited feedback.
