Apple is not only looking to maximize the efficiency of health sensors in Apple, but also to minimize the space they take up by creating curved sensor elements to better integrate into the case.
A new patent application from Apple focuses on the specifics of how certain sensors could be deployed within Apple. However, at the end of the day, it’s really all about ways to make you slimmer.
“It can be difficult to incorporate sensors such as optical sensors [which measure heart rate] in electronic devices, ”says Apple in“ Electronic devices with curved laminated film optical sensors ”.
“For example,” he continues, “the optical components to provide an electronic device with the desired functionality may be too large or unattractive to be incorporated into the electronic device.”
As with all patent applications, this one attempts to cover all possibilities by saying that it covers everything from a laptop to “a computer screen containing an on-board computer”, or “a wristband device,” a hanger, headset, or earpiece device, “and so on. If it can accommodate an optical sensor, Apple wants it to be covered by this app.
However, this is really the Apple. “The portable device can have a portable enclosure in which the optical sensor is mounted,” he says. “During operation, light from the light source may pass through a transparent part of the housing, may be reflected by an external object such as a wrist or other part of a user’s body, and may be received by the photodetectors. after passing through the light control elements. ”
“Light controls can be arranged in a ring with a center and can have curved shapes with concave surfaces facing the center,” he continues.

This is the key element, the way in which such optical sensors can be arranged and also curved, to take up as little space as possible. “Each light control element can be formed from a stack of laminated folded light control films,” says Apple. “The light control films for the stack can be pressed into desired folded shapes using a laminating tool with curved surfaces.”
Space within the Apple is still at an absolute premium. However, this patent application is credited to Tyler S. Bushell, who previously filed patents relating to the Digital Crown.
One is to transform the crown into a touch zone that recognizes gestures, while the other offers to operate it like a joystick. Both of these could free up space by removing the moving parts of the Digital Crown inside the Apple case.
