    I am looking to establish a long-term relationship with an electrical engineer with embedded design experience for several projects. The initial project is an electronic device that embodies the following sensors/capabilities:Heart Rate - Electrocardiogram (ECG/EKG) + Respiration3 or 6 axis Accelerometer - Motion and gesture recognitionTemperature SensorOLED Display Bluetooth Low Energy (BLE)Wireless Access Point/Gateway to transfer sensor information to cloud for evaluation/illustration/etc. If the engineer believes it is possible to incorporate a GPS without suffering too much battery life, then GPS capability would be great, too. If the engineer believes it is possible to incorporate wireless charging or actually motion charging (preferred), then that would be great, too. There is at least 3 other projects which incorporate the sensors above in various other fashions. Please send me a private message with your thoughts/estimates/questions/concerns and ideas. Additional information can be provided to you at any time.

    I am looking for a subcontractor or agency with good digital design skills. I have various projects that need doing and so am looking primarily for a long term relationship with the possibility of subcontracting all our design work overseas.Initially I have a requirement to transmit YUV422 digital video over 20m in an industrial environment. A document showing the block diagram is attached. The specification provided will obviously have to be firmed up but initially I am looking for expression of interests in working on this project and an estimated price and timescale for the work. The price can be confirmed after discussion and a detailed specification prepared.

    I have some code for a small 4 process scheduler. The main point is that it looks for the requests, if there is request it starts counting until specific number, then generates ready, and keeps scanning for the next request. I already have most of the code, though the logic is not working properly. I need someone to look at it, and fix my errors. Please note that there isn&quot;t much code. There is around 200 lines of code.

    I need you to create code using the liquid crystal library to read the co2 levels in real time printed to the LCD screen. Also show if valve status: Open or Closed. The co2 levels will show in % instead of PPM. For example 40000 PPM will read as 4.00%The co2 threshold level will still be set through ethernet on the server, unless this can be set using the lcd shield keypad buttons. If can be set with buttons Up and Down will move the 4 up and down. Pressing select or whatever other button will allow you to move the .00 part of the 4.00% up or down.Let me know if you have any questions or need further details.

    I am looking to develop a consumer product that is able to transmit temperature wirelessly, something similar to this will require much smaller end/handle. Will need to be able to give very fast readings so most likely utilise a K or J type probe. Does not need to transmit far, less than a meter. It also will require its own display rather than an app.

This work presents the architecture of an optimized complex matrix inversion using GAUSS-JORDAN elimination (GJ-elimination) on FPGA with single precision<br />floating-point representation to be used in MIMO-OFDM receiver. This module consists of single precision floating point arithmetic components and control unit which perform the GJ-elimination algorithm. The proposed architecture<br />performs the GJ-elimination for complex matrix element by element. Only critical arithmetic operations are calculated to<br />get
