Android phones can now send medical data during 911 calls

Engadget - Fri, 2023-12-08 05:45

Some Android users are getting an update that could literally save their lives one day. Android users who have a device with the Personal Safety app can now opt-in to sharing medical information with first responders when calling or texting 911. The feature has been available for iPhone and Apple Watch users since the rollout of iOS 13.5 in 2020.

Android users can add information such as caller name, allergies, emergency contacts and preexisting medical conditions. "This is when the information you put inside your phone becomes useful to 911," Tenea Reddick, ECC director at Baltimore City Fire Department, said in a statement. "This information is available to use before the dispatch, and before the responders arrive. It saves so much time because we already know what we're responding to and what we need." The feature is especially beneficial if the person contacting 911 is unable to communicate.

For now, this feature is only available on Androids with the Personal Safety app, such as the Nothing Phone 1 and the Google Pixel 4 through Google Pixel 8 Pro. Anyone with these devices can enable the new feature by going to the "Your info" section of the Personal Safety app. From there, they can click "Emergency info access" and then "Share during emergency call." 

Android and Apple's services are run by RapidSOS, a safety platform that securely shares critical information in times of crisis to over 16,000 911 and field responder agencies. Apple users can access Medical ID, a feature in the Health app that, similar to Android's Personal Safety app, stores information such as blood type, emergency contacts, allergies and preexisting medical conditions. RapidSOS shares this data with first responders, who can also determine a person's location if they call 911 in an area with Enhanced Emergency Data services. Android users have also had the ability to send location data through RapidSOS since 2018.

Nikon Makes Special Firmware For NASA To Block Galactic Cosmic Rays In Photos

SlashDot - Fri, 2023-12-08 05:00
In an exclusive interview with PetaPixel, astronaut Don Pettit reveals the changes that Nikon makes to its firmware especially for NASA. From the report: Galactic cosmic rays are high-energy particles that originate from outside the solar system that likely come from explosive events such as a supernova. They are bad news for cameras in space -- damaging the sensor and spoiling photos -- so Nikon made special firmware for NASA to limit the harm. Pettit tells PetaPixel that Nikon changed the in-camera noise reduction settings to battle the cosmic rays -- noise is unwanted texture and blur on photos. Normal cameras have in-camera noise reduction for exposures equal to or longer than one second. This is because camera manufacturers don't think photographers need noise reduction for shorter exposures because there's no noise to reduce. But in space, that's not true. "Our cameras in space get sensor damage from galactic cosmic rays and after about six months we replace all the cameras but you still have cameras with significant cosmic ray damage," explains Pettit. "It shows up at fast shutter speeds, not just the slow ones. So we got Nikon to change the algorithm so that it can do in-camera noise reduction at shutter speeds of up to 500th of a second." Pettit says Nikon's in-camera noise reduction "does wonders" for getting rid of the cosmic ray damage and that "trying to get rid of it after the fact is really difficult." That's not the only special firmware feature that Nikon makes for NASA; photographers who shoot enough photos know that the file naming system resets itself eventually which is no good for the space agency's astronauts. "The file naming system on a standard digital system will repeat every so often and we can't have two pictures with the same number," explains Pettit. "We'll take half a million pictures with the crew on orbit and so Nikon has changed the way the RAW files are numbered so that there will be no two with the same file number." The report notes that NASA started using Nikon film cameras in 1971, shortly after the Apollo era; "in part because Nikon is so good at making custom modifications that help the astronauts." Previously, the agency used boxy, black Hasselblad cameras.
