A self-defense headband that creates a personal electromagnetic cocoon around the wearer's own neural interface, protecting against external BCI intrusion attempts. Unlike NullPoint's offensive products that disrupt attackers' augmentations, the CV-1 is purely defensive — it generates a precisely calibrated interference pattern that blocks unauthorized wireless access to the wearer's BCI without disrupting the interface's normal function.

The CV-1 addresses a growing threat in GLMZ: neural hacking. As BCI technology has become ubiquitous, so have tools for wireless BCI intrusion — devices that can access a victim's neural interface to inject sensory hallucinations, read surface thoughts, trigger pain responses, or disable motor control. These attacks are difficult to detect and nearly impossible to defend against without hardware-level protection. The CV-1 provides that protection in a wearable form factor.

The headband uses a thin conductive mesh that, when powered, generates a white-noise electromagnetic shell around the wearer's cranial BCI hardware. This shell is transparent to the wearer's own BCI signals (which are calibrated during a one-time setup process) but blocks external signals that don't match the authorized pattern. The CV-1 costs Φ450 and is available in several widths and fabric covers to blend with different styles. NullPoint's marketing for the CV-1 is notably more mainstream than their offensive products — protecting your own brain is a less controversial proposition than disrupting someone else's.
