US Patent 1Patent Number: US 8395496 B2Patent Title: Miniature modular wireless sensorFiling Date: Mar 27, 2008

Summary of Patent: A wireless sensor device that is modular, such that the battery pack, sensor, and transceiver all move together/apart.

Infringement? Why/why not?: No, this is just patenting the way the modules snap together.

How can you design around patent?: This idea is very similar, however, ours will be a combined system.

42

US Patent 2Patent Number: EP 2582182 A1Patent Title: Bluetooth scatternet tree formation for wireless sensor networksFiling Date: Apr 19, 2012

Summary of PatentA novel way to transmit data over Bluetooth network

Infringement? Why/whynot? No, we will use standard transmission.

How can you design around patent?: We should be able to come up with a different transmission scheme. This patent only has to do with the transmission tree.

43

US Patent 3Patent Number: CN 203466979 UPatent Title: Self-positioning Bluetooth wireless sensor network node moduleFiling Date: Sep 23, 2013

Summary of PatentA sensor network that self-positions itself.

Infringement? Why/whynot? No.

How can you design around patent?: This patent is in regard to a self-positioning sensor used to maintain a better Bluetooth connection. This will not be a factor because it is out of the scope of our project.
