Usb 6001 daq

A force-sensing casing for the Philips XL14-3 xMATRIX ultrasound probe was assembled from 3-D printed from ASA plastic shells (MakerBot Industries, LLC, New York City, New York, United States) and an aluminum frame. Within the casing are an LSB205 S-beam load cell (FUTEK Advanced Sensor Technology, Inc.; Irvine, California, United States) to measure force applied to the ultrasound probe imaging surface and an ADXL335 accelerometer (Analog Devices, Inc., Wilmington, Massachusetts, United States) to provide probe orientation information and account for its effects on force measurement. The load cell signal is amplified by the IAA100 differential amplifier (FUTEK Advanced Sensor Technology, Inc.; Irvine, California, United States), which digitizes, along with the accelerometer signal, into the USB-6001 DAQ (National Instruments; Austin, Texas, United States). More detail on the force coupling is provided in the Supplementary Information.

The behavior board are composed of an aluminum plate, a plastic food reservoir, and a plastic cover based on the design of the FLIC, see Additional file 2: Fig. S2. A custom-made circuit board (AutoDesk EAGLE design .brd files available upon request) allows for the use of 8 wells and has receiving slots for 4 current resistor modules. The printed circuit board, the resistor modules, and the NI USB 6001 DAQ contain all the electronics needed for signal recognition, power supply to the board, and signal forwarding contacts to a computer for data acquisition. The printed circuit board contains two non-inverting operational amplifiers to provide a systemic gain of approximately 1.2, and it also contains 2 × 6 board-to-board male contacts for the attachment of resistor modules to the printed circuit board. The resistor module is the component that supplies current to each well. It contains two customizable current-limiting resistors, one for each well of a 2-well choice arena, and four gain resistors: two per well. The current-limiting resistors are used to regulate the amount of electrical current permitted to pass through the flies.

The DLP used in the experiments is a DLP LightCrafter 4500 from Texas Instruments. It contains a DMD and three coloured light sources (red, green and blue). A built-in optical system is used to project the patterns onto the scene. The photodetector used is PDA36A-EC from Thorlabs, and the electrical signal is digitalized with NI USB-6001 DAQ. All the experimental results were acquired with a Lenovo ThinkPad E531 laptop with 12GB of RAM and an Intel Core i7 2.20 GHz processor. The biological images used in the simulations correspond to different samples from two slide sets from Carolina (#292148A and #293708).
