Application of infrared sensing technology in food detection
Using infrared sensor to collect the spectrum of the target object. The system can use infrared spectrum, visible camera images and/or data from other sensors to characterize the target object alone or in combination, and may be used in Apple's head-mounted augmented reality device. For example, the system can be used for tasks such as food image recognition. Some information stored in the database can be triggered by image recognition of food. This information includes some food characteristics, such as freshness, fat content, food type, sweetness and so on. Therefore, the maturity and calorie content of food can be evaluated.
Apple Patent 1, MacBook Heart Rate Measurement: According to the patent report, Macbook is equipped with a processing unit operable to transmit light energy to the user's body parts through a first group of micro-perforations, receive the reflected part of light energy from the user's body parts through a second group of micro-perforations, and analyze the reflected part of light energy to determine this information. According to the chart, the MacBook may support the measurement of heart rate.
2. Apple VR optical system: According to the patent report, the optical system can be a catadioptric optical system with one or more lens elements. The lens elements may include plano-convex lenses and plano-concave lenses. A partial mirror may be formed on the convex surface of a plano-convex lens. The reflective polarizer may be formed on the plane of a plano-convex lens or on the concave surface of a plano-concave lens. An additional quarter-wave plate may be located between the reflective polarizer and the partial mirror.
3. Apple's 5G/LTE dual connection: According to the patent report, Apple filed a patent application in February 2065438+2008, mainly supporting the iPhone's 5G/LTE dual connection and dual connection. The wireless device may be configured to send a request to attach to a first network node opeRATing according to a first rat, and send an indication that the wireless device can maintain a substantially concurrent connection with the first network node and a second network node operating according to a second rat. The wireless device may also be configured to send a request to attach to a second network node. The request may include an indication that the wireless device can maintain a substantially concurrent connection with the first network node and the second network node.
