Mems design jobs

Hi Julian A., I noticed your profile and would like to offer you my project. We can discuss any details over chat. I am looking for help defining the use of a 4 channel 24bit ADC. I have various MEMS sensors that will feed into the part and need a clear development "road map" that defines the various settings of the part, including filters and optimal methods to drive down noise. I set the hours only as 1 until we can discuss and you can tell me what you think.

well already have site but working on it independently need help with upgrading it , like the front page would like more animation or effects like me talking or pulling mems out a cloud or doing a video and sending it to you and you adding effects i do not know , but more effects and dazzle and helping me to direct people to my other links separately from my website if there looking for funding they can go directly from internet by googling funding for business and go directly to that page instead of the front home page etc , can you take a picture and add and add or change color in my wardrobe and cut background out

Firmware for LIDAR and MEMS IMU (accelerometer/gyro) data collection and processing. The firmware will simply collect streaming LIDAR data into a 2,520 circular DMA buffer via UART at 230,400 baud. The IMU is a LSM6DS3US via I2C that will trip a hardware interrupt on the STM32F0 when the measurement data is ready. The STM32F0 will read the IMU data and calculate 3 variables regarding the physical movement of the sensor on a 2d plane in mm and rotation in degrees. The variables are X in mm, Y in mm and Rotation in degrees. When 0x67 is received over the second UART 2, the three navigation variables and the entire contents of the UART 1 circular dma buffer will be transmitted to UART 2. To make this simple for you, we will provide a functioning in-house development PCB package that ...

Hi, I have the nRF52840-DK and need to connect the ICS-43432 digital I2 S MEMS microphone. I need to know how to connect the ICS-43432 chip via I2S. Then I need a program that can stream data from the microphone chip and store for example 30 seconds of streaming data in the memory. The lenght of the continuous sampled file should be possible to set via a parameter. I have planned to connect the MEMS microphone to the nRF52840 board by using a simple development board => If this looks ok I have more work for you on the same project!

We are looking for an expert in Speech to Text / Natural Language Open Source Code. Our product's primary interface is with voice commands. We have a MEMS microphone and speaker. Economically, it is simply not viable to use cloud services such as Google's, Alexa's, or IBM's Voice APIs. The user interaction with our device is very simple and limited to only a few commands/actions. It should be possible to host our own OPEN SOURCE Speech to Text / Natural Language API and allow our own devices to connect to it to convert speech to text, determine the nature of the command, take appropriate action and then return a text that is converted to speech for the user to hear or text to initiate a pre-recorded message. In addition, we would also like to provide the cap...

...disadvantages of GPS, but its accuracy deteriorates in the long-term due to sensor error. Especially the error of MEMS INS increases rapidly due to huge errors of low cost MEMS sensor. Integration both INS and GPS provides performance as a reliable navigation system .The measurements from MEMS INS with GPS are mixed using data fusion technologies such as Kalman filter (KF) to generate the optimal PVA solution .One existing problem of such cost-effective integration system is the heavy reliance on GPS signal availability. The system PVA accuracy would degrade sharply without GPS update due to the poor performance of low-cost MEMS inertial sensors. An integrated system of GPS and Low cost MEMS INS is often used in UGV. To overcome the limitations. AI usi...

design mems switch I need to design MEMS SPST switch (cantilever or bridge type, we can discuss) by using ANSYS or COMSOL. It will be used for reconfigurable antennas. But in this work, only the switch design is needed. """"It is not too important which software will be used, important thing is create graphs according to given R and C values. And also the mems switch structure doesn't need to be too complex, it can be similar to the structure at Comsol MEMS tutorial"""" It can be similar to comsol mems switch that is attached so I think it's not so complex project. The structure doesnt need to be complex, it should only answers the values of R and C budget for this work is 30...

I have a GUI for displaying 4x4 temperature array and ambient temperature from from MEMS sensor and i also have a calculation panel for calculating the temperature of solar cell (looping and delayReceive) ,so what i need now ,is to construct a log message which shows the message of "the hotspot is detect on [x,y]" if hotspot is spotted (if one of the array temperature is higher than the calculation temperature .and expect the hotspot could be more than 1 location) ,else show message " no hotspot occur" . the component i used for my project is D6T omron MEMS sensor and a USB webcam . Additional quest :Superimpose the video with the UIcontrol (static text) question : i know that UIcontrol (Static Text) doesn't have the feature for altering alpha v...

I need to create a sound level meter for ambients with 4 MEMS digital microphone, I2S protocol. Also need to show those infos in a 7" LCD display and save those info to a file on the sd card. The hardware connection and communication between the Raspi Pi to communicate with the ICS43434 I2S Digital MEMS Microphone is done, the mic outputs 2 words of 32 bits each, for right and left channels, from those 32 bits, 24 bits are used for signal data as you can see on the images. The code has to be well commented and a simple tutorial on how to use/implement the code /libraries should be created. The main goal is to get the data from each microphone and transform this digital data to decibel (dB) with A-Weighting scale, and also make a Fast Fourier Transform (FFT) to dis...

Hi ! I would like to create a COMSOL tutorial, but I don't have enough time. Therefore, I am looking for someone who could extend an existing tutorial. I am searching for a COMSOL specialist. This is the COMSOL tutorial which should be extended: I have included to this project the original tutorial file, where I included the things that should be added. Please note that the added information should be detailed and clear.

I would like to have a fully documented simulation of an electrostatic actuation of a mems structure. The mems structure is described in the attached document. I am interested to know the deflection and stress with respect to the applied voltage. All simulation should be done by an *open source software of your choice*. Please also include a tutorial on how to set up the open source software.

Hi Muhammad H., I noticed your profile and would like to offer you my project. We can discuss any details over chat. Basically, I have a schematic of MEMS sensors feeding an analog processing chip, to an ADC to a PIC micro. we built 3 for prototype test and there is a short that we simply cannot find. At this point, all I am looking for is help finding the short before building more. Could be a manufacturing problem, just not sure.

Basically, I have a schematic of MEMS sensors feeding an analog processing chip, to an ADC to a PIC micro. we built 3 PCBs for prototype test. the first was populated and had a short. then we tested the bare PCB and there is a short that we simply cannot find. At this point, all I am looking for is help finding the short before building more. Could be a manufacturing problem, just not sure. I have an Eagle project and the generated gerbers and schematic.
