A system, for tracking fingers of a hand, includes: a sensor patch and a processor. The sensor patch includes: a flexible substrate layer; a light emitting layer attached to the flexible substrate layer; and a photodiode disposed between the light emitting layer a surface of the sensor patch that contacts the hand. The light emitting layer is configured to conform to a skin surface of a backside of the hand and to emit a first wavelength of light. The processor is configured to: control emission of the first wavelength of light by the light emitting layer; analyze backscattered light intensities from the skin surface of the backside of the hand that are detected by the photodiode; determine finger pose information based on the backscattered light intensities; and transmit the finger pose information.

A method and system providing an anti-counterfeiting label or mark, using ordinary inkjet printers, take advantage of a phenomenon called a coffee ring pattern, something that inkjet printers. Even the same inkjet printer can output different patterns under different conditions. As a result, the likelihood of reproduction of a particular printer's coffee ring pattern using another printer is so low as to be negligible. It is possible to capture images of the coffee rings using a smartphone camera. The coffee ring approach may be used on any labels or packages on which inkjet printing can be used.

A carbon nanotube (CNT) resonator includes: a first CNT having a first end and a second end both fixed to a substrate; and a second CNT having a first end fixed to the substrate. The second CNT creates a Van der Waals (VdW) bond with the first CNT where the second CNT overlaps the first CNT. A length of the VdW bond along a distance between the first and the second CNTs oscillates based on a DC voltage applied between the first end of the first CNT and the first end of the second CNT. An electrical current passing through the first and the second CNTs using the VdW bond oscillates based on the oscillation of the length of the VdW bond.

A fabrication method achieves bump bonds (to connect two electronic devices) with a pitch of less than 20 &#x3bc;m using UV-curable conductive epoxy resin cured with an array of nano-LEDs. Nano-LEDs are devices with sizes less than or equal to 5 &#x3bc;m, typically arranged in an array. After deposition of the uncured conductive epoxy layer, the nano-LED array enables a fast curing of the bumps with high spatial resolution. Next, the uncured resin is washed off and the chips are assembled, before final thermal curing takes place.

A video surveillance system with real-time object re-identification capabilities, which employs an object re-identification algorithm and an edge computing architecture. An operator monitors video images from the multiple cameras, and when a target object is observed, a target image containing the object is transmitted to all video cameras for object re-identification. Each video camera has dedicated processing circuitry that performs an object re-identification algorithm to identify the target in video images captured by that camera in real time. The algorithm calculates a frequency domain similarity measure between the target image and test images captured by the camera. The similarity measure in the frequency domain is calculated as a dot product of the 1D discrete Fourier transforms of the target image data and of the test image data. The multiple cameras also transmit object re-identification results to each other to achieve more efficient and intelligent object re-identification.
