International Classification:

H04N 5/225
H05K 7/20

Abstract:

An electronic component assembly having thermal pads with thermal vias coupling an image sensor and a camera board fab is provided for heat dissipation. The electronic component assembly can include: a circuit board having at least one thermal pad disposed on a top surface of the circuit board; and an image sensor disposed on the top surface of the circuit board, having at least one conductive pad disposed at at least one corner of the image sensor. The at least one thermal pad is coupled to the at least one conductive pad of the image sensor and the at least one thermal pad is formed with a plurality of first thermal vias penetrating the thermal pad and the circuit board for transfer of heat of the image sensor.

Abstract:

Systems for protein quantitation using a Fabry-Perot interferometer. In one arrangement, a quantitation device includes an infrared source, a sample holder, and a Fabry-Perot interferometer positioned to receive infrared radiation from the source passing through a sample on the sample holder. A band pass optical filter sets the working range of the interferometer, and radiation exiting the interferometer falls on a detector that produces a signal indicating the intensity of the received radiation. A controller causes the interferometer to be tuned to a number of different resonance wavelengths and receives the intensity signals, for determination of an absorbance spectrum.

International Classification:

G01B 21/20

US Classification:

702168

Abstract:

Described herein are methods, systems and devices for image-guided, computer-assisted surgical procedures, in particular for intra-operative registration of anatomical structures. Embodiments of the invention may enable a user to register the surface of an anatomical structure intra-operatively in an interactive, computer-guided process. The user may send information about acquired data points to the computer, and the computer may evaluate the aggregate of data points, optionally provide instructions to the user for acquisition of additional data points, and signal to the user when sufficient data points have been acquired for registration of the surface of the anatomical structure.
