We like to build a prototype product using fiber optics and by utilizing its highly sensitive micro bend multimode fiber optic sensor for simultaneous measurement of Breathing rate and Heart rate. It will be based on the technology developed by some of industry's current products. We have some published journals and utility patents information. And the we already had the design concept approved by several fiber optic expert. The right candidate need to review our design concept first,and working with us starting from scratch.The Target is to provide us a functional prototype(once the design complete we will have our in house technician build the prototype). The Key skills we looking for are: 1.Fiber optic expert:able to help has find right Fiber optic cable and associate fiber optic components. 2.Material engineer knowledge. 3.PCB design:PCB Design/Develop will be involved in this project. Firmware skills will be a plus. Labview experience will be a plus Wireless Design experience ...

Design and build a hub that will receive data from various z-wave sensors (motion, door contact, temperature, humidity, etc.) and then send that data to our web based database via wifi. The hub will need to have an ac power source, receiver of z-wave, and wifi connection to a home network. The hub will have to have an easy method to pair z-wave sensors...and add the sensors to database. The hub will need to have an easy method to connect to wifi network- WPS or similar. The Hub production cost can not exceed 35$- so pay attention to wifi chip be used. The bid must include design, building 3 prototypes, shipping these to USA, and all firmware. Working prototypes must be completed within 14 days of project start date. Data transfer- The Api we provide will be POST method. The data will be pass in JSON format like following keywords { sensormacaddress: Datatype String, sensortype: Datatype String, batterylevel: Datatype Integer, sensorevent: Datatype Integer, year: Datatype ...

i want to build a VCSEL driver that can drive the VCSEL at 120 Mbps at a low power consumption of 3 mW, this VCSEL should send the data accross skin and i want to see the transmitted data on the receiver from the other side of the skin. the space between the transmitter and receiver should not be more than 3 mm, and the skin should be in contact with the VCSEL. i want this system to be build on PCBs and i need it to be ready in 25 days if possible.

Looking for a USA BASED person or firm to prototype a piece of networking hardware containing a embedded linux OS and 2.4Ghz and 5Ghz WiFi receiver. The form factor is supposed to be no bigger or similar to the Belkin WeMo Insight device (see   [obscured]  /1LjeGkv for image). The purpose of the device is to monitor, log and share (with a server) wifi signal information.

I require assistance with creating a PoC device that can listen in on a specific RF signal generated by a medical transmitter (attached to a constant glucose monitor), decode that data and store it. Ideally, the device will be based on a Raspberry Pi, although I will be happy to accommodate other possibilities. The system needs to: 1. Be able to listen on several frequencies (868.35, 916.5 are two I am pretty certain need to be supported) 2. Capture a very short signal (a few milliseconds) coming in at fixed intervals (e.g. every 5 minutes). 3. Decode signal (which should be unencrypted), and save its digital content The device emitting the signal is this:   [obscured]  -diabetes.com.au/wcm/groups/mdtcom_sg/@mdt/@ap/@au/@diabetes/documents/documents/contrib_107985.pdf (fcc db:   [obscured]  /oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&RequestTimeout=500&calledFromFrame=N&application_id=701227&fcc_id=OH27703) (and belongs to my 5 year old son, wh...
