INTELLECTUAL PROPERTY

Original thinking.
Documented invention.

Mad develops technology for personal, accessible and adaptable environments. Patented methods, registered technology names and continuing patent-pending work connect media delivery, governed intelligence, immersive sound, guidance, spatial interpretation and privacy-conscious sensing.

INVENTION AND IMPLEMENTATION

Read the record and the capability together.

A patent record describes an invention and its legal status. A technology page describes the implemented functions, demonstrations and continuing development. The project scope identifies which capabilities are included and what commissioning evidence is required.

WHY WE INVENT

Better experiences need new engineering.

A visitor should be able to encounter a story in their language, at a level that interests them and through a form they can use. A designer should be able to create an ambitious experience and have its intent survive daily operation. Those are practical problems that drive Mad's research and development.

Our technology connects media, people and physical places. The published patent records below address methods for selecting, customizing and delivering content, including recognition and audience context. They form part of a wider body of engineering work that continues to grow.

From a method to an environment

QuickSilver® provides the distributed compute foundation. The AV++® family connects personalization, multilingual media, accessibility and interaction. Mad Intelligence™ brings the next question into focus: how an environment can keep meeting the designer's intent as conditions change.

The granted records, newer applications and registered names each have a distinct place in that story. This page keeps those records separate and links to public sources for deeper review.

CONTINUING RESEARCH AND DEVELOPMENT

The next chapter is already being engineered.

Patent-pending work connects continuing engineering, governed intelligence, immersive sound, accessible guidance, spatial interpretation and privacy-conscious sensing. Each addresses a practical need: help an environment deliver its intended experience as people, conditions and technology change.

PATENT PENDING

Mad Intelligence™

Mad Intelligence brings continuing engineering into the life of an installation. Its purpose is to preserve the designer's intent after the engineering team leaves site, using evidence from the environment to identify change and guide an authorized response.

A U.S. provisional patent application has been filed for this work. The architecture connects the intended result, the available capabilities and the evidence of delivery, bringing together WorldModel's understanding of the venue, Hatter's acoustic care and the wider AV++® family.

Mad Hatter™

Hatter is a DSP and an acoustic experience engine. Its patent-pending work connects the processing and control audio professionals expect with creative soundscape authoring, immersive listening, room adaptation, accessible guidance, personal media delivery and continuing acoustic verification.

The aim is sound that continues to serve the intended experience as the room, the audience or the equipment changes. Shared timing, measured results and clear operating status help the connected system assess what it is actually delivering. Working capabilities and newer development paths are identified in the detailed Hatter descriptions.

WorldModel™

WorldModel provides an architecture for understanding what is happening in an intelligent environment, what is permitted and how its systems should act together. Its patent-pending work connects venue context, consent, policy and coordination so that adaptation can remain accountable.

The public framework explains the responsibilities of its architectural layers, the policies that apply across them and the way participating venues can coordinate while retaining local authority. It gives designers and operators a shared basis for connecting new capabilities to the purpose and rules of the environment.

PATENT PENDING · UNDER DEVELOPMENT

WonderLens™

WonderLens is Mad's spatial augmented reality program. It explores digital interpretation aligned with physical artifacts, exhibits and environments, adding context and visual depth to what a visitor is looking at.

The work connects spatial overlays with the QuickSilver® computing foundation and WorldModel's understanding of the venue. WonderLens is under development. The hardware, content and complete delivery path must be established for the intended application.

PATENT PENDING

CaterPillar™

CaterPillar is Mad's guidance system for visitors who are blind or have low vision. Spatially located audio cues help people orient, choose a route and find exhibits, services and other destinations within a venue.

Its station-based approach works alongside an ordinary white cane and can provide guidance without a phone, wearable, registration or recognition. Further integration with Hatter's venue loudspeakers and personal audio capabilities is under development, extending the ways guidance can accompany a visitor through the space.

CONNECTED INVENTION

More ways to understand and serve the experience.

Hatter's filed work also encompasses the following technologies and capability areas. They contribute to the connected architecture, with implementation and physical qualification progressing at the level of each capability and installation.

Mad Presence™

Mad Presence™ uses two loudspeakers per listener position and head tracking to connect an authored spatial scene with the listener. It already operates on the Mac, alongside supported headphone and earbud listening. Installed arrangements are configured and tested for their own listening region and acoustic result.

Explore immersive listening

Mad Nulling™

Ongoing work aims to reduce the effect of one exhibit's sound on an adjacent exhibit. It considers loudspeakers, processing, acoustics, geometry, reflections and program material, with results evaluated where neighboring visitors listen.

Explore acoustic care

MTCL™

The Microphone That Cannot Listen™ gives Hatter limited acoustic measurements, such as level, known-signal presence and arrival time. Its privacy build excludes a raw audio-stream output, helping the system verify its sound while respecting visitors' conversations.

Explore private acoustic measurement

CTCS™

The Camera That Cannot See™ is the developing dedicated camera node for head position and orientation. It is designed to process images locally and pass only pose and tracking quality, with no pictures stored or sent and no identity recognition. It extends Hatter's working local head tracking toward installation use.

Explore optical head tracking

Acoustic location and measurement

Further Hatter work explores using venue sound to locate a participating phone, alongside qualified phones and tablets as acoustic measurement instruments. These development paths connect position, proximity and evidence of sound delivery to the venue's operation; device qualification and physical testing establish their useful accuracy.

Explore the developing capabilities

Located, personal media delivery

New integration work connects a participating visitor's location and chosen language, interests and accessibility preferences with synchronized personal media. It brings Hatter together with Alice® and Lory® so audio, captions and other supported forms can follow the visit, with consent and venue policy defining the permitted use of information.

BUILDING TOGETHER

Put the right technology to work.

Mad welcomes conversations with designers, integrators, platform developers, venue operators and strategic partners. A productive discussion starts with the intended experience, the application, the territory and the practical responsibilities of each participant.

From there, we can identify the relevant technology, an appropriate demonstration and the engineering or licensing discussion needed to move forward.
