静かに、そばに。 守り · まもり
Mamori is a concept for a small tabletop device for an older relative’s home. It is designed to offer a big help button, read the room air, and keep its microphone off unless you can see that it is on. There is no camera.
The idea
Each one is a design intent, not a tested result. The limits sit right next to the promise.
1 Emergency warning
A press would sound an alarm in the room, turn the ring red and show “Help called”. If a family node is paired, it would send an alert there too.
Limit: only helps if the button can be reached. It is not an emergency service and there is no guaranteed response.
2 Living signals
PM2.5, CO2 and VOC, temperature and humidity, shown as simple notes like “air looks stale”. Blood oxygen would be only through an optional contact accessory, with no claim.
Limit: room air readings, not health measurements. No claim about blood oxygen.
3 Fall alert, from a partner
Mamori has no fall sensor. A partner’s own wifi sensing box could raise a fall-event signal; Mamori is designed to pass it on to the paired node.
Limit: not validated. It may miss real events or raise false ones.
4 Optional call
Designed to call another paired node over the internet. The ring would pulse amber and the display would say a call is on.
Limit: designed to be off while the shutter is closed. Not an emergency call line.
5 Full privacy
No camera and no image sensor in the concept. The mic LED is designed to sit on the mic’s power line, so no light would mean no mic. A slider would cover the mic and cut its power.
Limit: the circuit would need an independent check before anyone relies on it.

APoint 1 · Emergency warning
A big physical button on top. A press would sound a local alarm, turn the ring red and show “Help called” on the display. If a family node is paired, it would also send an alert there.
Honest limit: only works if the person can reach and press it. It is not an emergency service; there is no guaranteed response.

Privacy, by hardware
Try it. The ring, the mic LED and the shutter tell the same story. This is a live demo of the design intent; nothing here uses your microphone.
Private. The microphone would have no power.
The concept has no camera or image sensor, so it is designed to make no images. Sound would not be stored. The partner’s wifi sensing box is a separate device with its own privacy terms, which this concept does not control.
How it would work
A direct link between paired nodes is the intent. If nothing is paired, everything stays in the room.

These are room air readings, not health measurements. Low-cost sensors drift and need calibration; a spot near a heater skews them.
Honest answers
No. It is a concept, not a medical device, and it makes no medical claim. It would not replace a doctor, a carer or an emergency service.
Mamori itself has no fall sensor. The idea is that a partner’s own wifi sensing sensor, a separate box, could raise a fall-event signal, and Mamori would pass it on to the paired node. That has not been validated: it may miss real events or raise false ones, and how well it works would depend on the partner’s sensor, the room and the setup.
No. The concept has no camera and no image sensor, so it is designed to make no images to store or send.
The design intent is no: the mic LED would be wired on the mic’s power line, so the mic would not be able to work without the light on, and a sliding shutter would cover the mic and cut its power. This hardware rule would need an independent check of the circuit before anyone relies on it. Sound would not be stored.
Not guaranteed. A press would sound a local alarm, which helps only if someone can hear it, and would send an alert to a paired family node if one is set up and the power and internet link work. It is not an emergency service.
It would read the room air: PM2.5, CO2/VOC, temperature and humidity. Those are not health measurements. Blood oxygen would only come from an optional contact accessory that would need its own separate validation; no claim is made about it.
No. This is a concept for discussion. There is nothing for sale, no account and no paid service. Mamori is a working name and has not been trademark-checked.
