Apple's sleep and health tracking ambitions extend to blankets and mattresses

Apple looks to be extending this current Beddit strip into a full-blown bed mat

Following many suggestions that Apple is bringing sleep tracking to the Apple Watch, the company appears poised to further delve into its Beddit purchase and develop bedding and blankets to monitor vital signs.

Sleep tracking has been coming to the Apple Watch for some time, and Apple even bought the Beddit third-party system for this purpose. But now a new patent suggests that the Apple Watch may not be needed as bedding and a mattress cover could be used instead.

"Traditionally, monitoring a person's sleep or vital signs has required expensive and bulky equipment," begins "Vital Signs Monitoring System," US Patent No 20200107785. It then points out that wearing such equipment makes the person uncomfortable, and so affects the very sleep patterns that it's trying to monitor.

This is specifically a criticism about the kind of sleep tracking that requires a stay in a medical facility, but it also makes points that could equally apply to an Apple Watch. Specifically, it says that currently any kind of worn device tends to be "configured to determine the vital signs based on one type of measurement or mode of operation."

What's more, an Apple Watch or any other device would monitor only the person wearing it. "[These] systems lack the capability of not only monitoring multiple users, but also incorporating the analysis of a first user into the analysis of a second user, whose sleep may be affected by the first user."

Apple's proposed solution, then, is effectively to have bedding that tracks the sleep of anyone lying on or under it. This appears to be an extension of Beddit's system, which saw a strip of material being placed under bedsheets and relaying data to an iPhone.

This extended version appears to suggest that instead of one short strip positioned under one part of a sleeping person's body, at least a larger portion of the bed would become a sensor.

"The monitoring system can include a plurality of sensors including, but not limited to, electrodes, piezoelectric sensors, temperature sensors, and accelerometers," says the patent. "Based on the measured values, the monitoring system can analyze the user's sleep, provide feedback and suggestions to the user, and/or can adjust or control the environmental conditions to improve the user's sleep."

That's you in bed with an Apple mat underneath and an Apple blanket. Look, this is useful.

While presumably adjusting the environmental conditions could involve data being sent to a HomeKit device to alter air conditioning, for instance, the patent refers more to providing a control system for the user. "[A] control panel can include a touch panel and/or display and be configured to interface with the user and/or a computer.... [It] can display heart rate, heart rate variability, respiratory rate, respiratory rate variability, user's motion, and user's temperature."

The mat, though, could also act as an electric underblanket and directly alter temperature itself. Apple refers to this as "active heating or cooling," and it would be more intelligent than a regular electric blanket, because it would adapt to more than one person. "[For example,] heating and/or cooling can be used to accommodate the differences in thermal comfort," it says.

So the mat would register a user's body pressing on it, and be able to distinguish between two users. The patent concentrates on very many ways that this can be done, for how it can determine "one or more physiological signals of a user," as well as of multiple users.

The invention is credited to two people at Apple, Shahrooz Shahparnia and Erno H. Klaassen. Both researchers hold multiple patents, but none clearly related to this.
