The BOUNCE™ Story: How We Got Here
Early in 2025, I, Rick Lawrence—a US Navy Data Systems Technician, ergo, a Veteran—suffered a severe fall and broke my arm. During my follow-up care, I met with my VA vascular surgeon, Dr. Halpren, Chief of Vascular Surgery at the Phoenix VA Hospital. Highly concerned by my elevated fall risk, she remarked half-jokingly that she wished she could just wrap me in bubble wrap.
On Christmas Eve 2025, that joke became a painful reality.
I slipped on a dog toy, broke my foot, severely injured my knee, and spent over two weeks confined to a hospital bed. During my grueling recovery, Dr. Halpren would visit during her daily rounds and discuss current "Personal Bubble Wrap" options and found that none existed like we were looking for.
As an engineer, I stopped wishing and started designing. During my lengthy recovery; BOUNCE™ was born.
The Invisible Crisis Facing Our Seniors & Veterans
We didn’t just set out to build a piece of assistive technology; we engineered a definitive response to a catastrophic public health epidemic. Falls are not random, isolated incidents; they are ordinary moments that turn fatal in milliseconds.
- The Leading Killer: For Americans aged 65 and older, falls are the number one cause of injury-related death—outranking motor vehicle accidents and firearms combined. Every year, over 43,000 older Americans lose their lives to a fall. With over 61 million Americans age 65 or older, the danger is only growing. Especially considering this is the fastest growing demographic in America.
- The Financial Bleed: Non-fatal falls drive over 3 million emergency room visits and over 1 million hospital admissions annually, inflicting an astronomical $80 billion annual drain on the U.S. healthcare system. Much of this burden ($53.3 billion) is borne directly by taxpayers through public programs, with the remaining balance spread across Medicare and other institutions.
- The Post-Admission Clock: A single serious fall can trigger an acute hospital stay averaging 5.5 to 7.3 days, ballooning to nearly 10 days for hip fractures. If a patient experiences institutional delays waiting for an open bed at a skilled nursing facility, that stay skyrockets to an average of 26.3 days, costing upwards of $70,000 per event.
The Post-Fall Trap
Existing market solutions are entirely reactive. Post-fall pendants and wall-mounted buttons do absolutely nothing to prevent the potential initial physical trauma—they simply alert emergency services after the damage is done.
When a hip fracture occurs, a person’s life trajectory changes permanently:
- The 1-Year Mortality Window: A hip fracture is a massive, systemic trauma. The one-year mortality rate sits between 15% and 30%.
- Loss of Autonomy: Fewer than half of all hip fracture survivors ever regain their pre-fall functional independence. Over 50% plunge into permanent dependence on caregivers, and the odds of requiring long-term nursing home placement surge 3.8 to 4.5-fold.
- The Fear-of-Falling Cycle: Even a non-injurious fall triggers a psychological trauma loop. The resulting fear causes elders to naturally restrict their mobility, accelerating muscle wasting (sarcopenia), worsening their balance, and ironically doubling the probability of a subsequent fall.
Our Approach: Pre-Impact Defiance
BOUNCE™ is built around a disruptive paradigm: Protection must adapt to people—not the other way around. In a real-world fall, ground impact occurs in a brutal 1/3 to 1/2 of a second (300 to 500 milliseconds). To potentially greatly reduce injuries risk and possibly save a life, protection must fully deploy in under 330 milliseconds. BOUNCE™ shatters this limitation and fully deploys under 150 milliseconds.
Operating at an ultra-high-speed telemetry rate of 1,600 Hz, our advanced hardware utilizes a Triple Modular Redundancy (TMR) sensor architecture. Three independent Inertial Measurements Units (IMU's) continuously stream 6-axis (x3=18-axis)kinematic data to a high-performance STM32 microcontroller via high-speed data lines. It’s designed and in prototyping now. The firmware implements a strict 2-of-3 voting system for extreme reliability:
[System Architecture Note]: By processing data 1,600 times per second across three redundant sensor paths, the system filters out structural noise and normal daily activities (like sitting or bending) with absolute fault-tolerant precision. It detects the exact millisecond an unrecoverable fall trajectory begins, finalizing the deployment command within 15 milliseconds of fall onset.
With a total system deployment response time clocking in under 150 milliseconds, the system commands a high-reliability firing circuit to execute a phased, multi-stage deployment sequence well before ground impact:
- Stage 1 (Vertical Stabilization): The system instantly deploys a lower "skirt" airbag to cushion the hips and pelvis to down below the knees.
- Stage 2 (Horizontal Containment): Milliseconds later, the upper airbag fires horizontally roughly 6 inches from the body before expanding upward. This horizontal deployment path safely captures and shields the upper torso, head, and arms, regardless of their position during the fall.

High-Speed Deployment Sequence
Frame 1: Fall Onset
As fast as 15 milliseconds, the sensor suite vote is 2of3 IMU's identifify the unrecoverable drop vector immediately upon detachment from the gravity threshold.
Frame 2: Pulse Signal Execution
The STM32 logic fires the execution pulse through the hardware lines instantly.
Frame 3: Rapid Expansion
Manifold pressures release structural air directly along the integrated guide channels.
Frame 4: Controlled Inflation
Full mechanical expansion achieves protective shape structural rigidity prior to body-to-floor contact.
From Conception to Fabrication-Ready in 5 Months
We didn't waste time. From the initial concept following my Christmas Eve fall to a Provisional Patent granted on Jan 22nd, 2026, to a finished, 100% production-ready hardware design took less than five months. Utilizing advanced modern ECAD tools, I designed, routed, and finalized a highly dense, professional-grade printed circuit board (PCB) that balances sensitive micro-volt telemetry paths with high-reliability triggering loops and sourced every component. See for yourself:
The manufacturing files are locked down. We aren't guessing if the hardware can be built; it is sitting on our drives ready for fabrication today. We are simply raising the funds to manufacture our physical pilot units and move directly into testing.
We are protecting Veterans and Seniors as they live their lives. Reliably first. Dignity always.
