Masimo is a medical device company that manufactures 100 million medical devices each year and is in need of streamlining their current process of inserting adhesive sensors into pouches. To increase the production volume, speed, and accuracy, Team Bondi has designed an automated pouch opener/presenter for Masimo to implement into their facilities. The system uses a Programmable Logic Controller (PLC) and sensors to control the pneumatics in order to grab a pouch from a hopper and then opens and presents the pouch to an operator for sensor insert.

The FPGA FM Synthesizer is a replacement for software-aided synthesis. Plugging in a MIDI keyboard, it processes the digital input bitstream and uses fixed-point DSP to output an analog sound wave. It can produce up to 16 voices, note bending, and can generate sine, square, sawtooth and triangle waves. Frequency modulation is done by selecting the amplitude and frequency of a modulating signal. This system uses a System-On-Chip, combining the flexibility of a processor and hardware acceleration of programmable logic.

Our innovative device is specifically designed to enable disabled golfers to enjoy the game of golf, even if they cannot swing a golf club. Our goal is to overcome the limitations posed by physical disabilities through a sophisticated mechanical design. With just the press of a button, our device will be able to launch a golf ball down the fairway, using an accessible control mechanism such as a sip-and-puff system. This means that wheelchair-bound users with limited mobility can now participate in this great sport and experience the joy of hitting a golf ball.

RES3RA is a deck-mounted attachment for Booz Allen Hamilton’s MANTAS (Man-Portable Tactical Autonomous System). The modular attachment will enhance the unmanned surface vessel’s ability to perform reconnaissance and surveillance missions. Currently, the delivery of surveillance payloads is performed by two operatives that jet ski to the target vessel and attach the payload to its hull with a long pole. The RES3RA aims to accomplish the same task in tandem with MANTAS, thus removing operatives from potential danger.
