A lock that is unlocked using vibrations conducted through the bones in the user’s hand. The user wears a wristband containing a haptic motor. The haptic motor generates a vibration signal that acts as the "key" to the lock. When the user touches their finger to the lock, the signal is transmitted through the user’s hand and is received at the lock. If the lock receives the correct "key", then it unlocks.

Problem Statement:

Radio frequency interference from cell phones disrupts measurements at the radio observatory in Arecibo, Puerto Rico. Many visitors do not comply when asked to turn their phones off or put them in airplane mode.

Description:

We are planning to design a handheld device that will be able to detect radio frequency interference from cell phones from approximately one meter away. This will allow someone to determine if a phone has been turned off or is in airplane mode.

The device will feature an RF front end consisting of antennas, filters, and matching networks. Multiple receiver chains may be used for different bands if necessary. They will feed into a detection circuit that will determine if the power within a given band is above a certain threshold. This information will be sent to a microcontroller that will provide visual/audible user feedback.
