Filed:

Dec 3, 2007

Appl. No.:

11/949578

Inventors:

David Patrick Fromm - Palo Alto CA, US
Richard Kenton Workman - Sunnyvale CA, US
John Paul Flowers - San Jose CA, US

International Classification:

G01B 5/28

US Classification:

73105

Abstract:

A scanning probe microscope and method for using the same are disclosed. The scanning probe microscope includes a probe, an electromechanical actuator that moves the sample relative to the probe, an external interface, and a controller. The probe has a tip that moves in response to an interaction between the tip and a local characteristic of a sample. The external interface provides a connection between the scanning probe microscope and a device external to the scanning probe microscope. The controller records scanning probe microscope data measurements, each scanning probe microscope data measurement including a location of the probe in the three dimensions and a label that uniquely identifies that measurement and allows that measurement to be correlated with data generated by a device that is external to the scanning probe microscope. The unique label could include the time at which the data measurement was made.

Abstract:

Improved sub-assemblies and methods of control for use in a diagnostic assay system adapted to receive an assay cartridge are provided herein. Such sub-assemblies include: a brushless DC motor, a door opening/closing mechanism and cartridge loading mechanism, a syringe and valve drive mechanism assembly, a sonication horn, a thermal control device and optical detection/excitation device. Such systems can further include a communications unit configured to wirelessly communicate with a mobile device of a user so as to receive a user input relating to functionality of the system with respect to an assay cartridge received therein and relaying a diagnostic result relating to the assay cartridge to the mobile device.
