As you go about your day, and when you bend your spine through slouching, etc., the carrying member changes its shape due to bending. As the strain gauge is attached to the carrying member, it can measure the bending as a measure of the change in its electrical resistance. In parallel, the changes in the orientation of your back are detected and measured by the tilt sensor (accelerometer). When your body is not vertically straight and is angled, the tilt sensor detects this change. The controller uses the readings from both the strain gauge and the tilt sensor to determine whether or not an unacceptable deviation has occurred. Combining data increases the accuracy of the device, thereby reducing the incidents of false positives. Once the device detects that your spine & posture isn’t in the correct shape, it’ll vibrate using the vibrator in the housing or you can set the device to send you an alert to your phone, etc. https://www.chendurs.com/blogs1/hydration-level monthly 0.5 2023-02-25 https://images.squarespace-cdn.com/content/v1/62abc76c40a7fa68c78f5f64/5f0c8fb5-e753-40ac-bf7c-343581b52fbd/Hydration+level+setup.png How Wellness gadgets works - S1 E11: How your Hydration levels are measured in a fitness watch? - Make it stand out Figure 1: Enlarged view of the arrangement of electrodes and meter in the watch band https://images.squarespace-cdn.com/content/v1/62abc76c40a7fa68c78f5f64/b711bcd2-f9c0-4153-b957-cc35ab20668e/hydration+level.PNG How Wellness gadgets works - S1 E11: How your Hydration levels are measured in a fitness watch? - Make it stand out Figure 2: Workflow of computing the hydration level in a fitness watch.

Infrared LED light will have a similar graph of its own. Every time our heart beats, the blood flow in our arteries increases (which means more light is reflected onto the photodiodes), but they remain constant in our veins. The photodiodes generate current accordingly over time with peaks during the heartbeats. https://www.chendurs.com/blogs1/how-do-pacemakers-work monthly 0.5 2023-02-25 https://images.squarespace-cdn.com/content/v1/62abc76c40a7fa68c78f5f64/1e898ff3-4b76-4ece-abeb-6cb98b30f0be/heartchamber.png How Wellness gadgets works - S1E9: How do Pacemakers work?

An electrical signal from the sinoatrial node (the green node not connected to any fibers in Figure 2.) causes the atrium to contract. Thus, opening the one-way valve for the blood to flow to the right and left ventricle chambers respectively. Now, the electrical signal from the atrioventricular node (the green node connected to fibers in Figure 2) causes the ventricles to contract, thereby pushing the blood from the right ventricle to the lungs and from the left ventricle to the body.

You can find a V-shaped fixture (on the removable part of the trimmer) that can move along with the moveable blade. When you attach the removable part of the trimmer to the casing, the motor’s protruding rod at the end always slides into this V-shaped fixture. This is due to the smaller offset of the rod from the center than the gap between the V-shape itself. By designing it this way, it is made sure that the motor and the V-shaped fixture will always be linked when the removable part of the trimmer is fixed. This linking is necessary to make the blades slide back and forth using the motor (mechanism discussed later). https://images.squarespace-cdn.com/content/v1/62abc76c40a7fa68c78f5f64/0d78abfd-68fe-4c50-b0f0-f5d358f5b012/bladegif.gif How Wellness gadgets works - S1E2: How do Electric beard trimmers work? - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/62abc76c40a7fa68c78f5f64/5d5e297d-e0b5-4882-9339-8909529b87e4/mechanism+gif.gif How Wellness gadgets works - S1E2: How do Electric beard trimmers work? - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://www.chendurs.com/blogs1/how-do-step-counters-work monthly 0.5 2024-02-04 https://images.squarespace-cdn.com/content/v1/62abc76c40a7fa68c78f5f64/59f48716-38e9-4810-b5da-86062735f0ff/filtering.png How Wellness gadgets works - S1E1: How do Step Counters work in your fitness watch? - Make it stand out Figure 1 - Source: Patent US20130191069A1 https://images.squarespace-cdn.com/content/v1/62abc76c40a7fa68c78f5f64/f84628bb-ea2e-43f1-bcfa-9ae50aa1e859/step-counting-algorithm.png How Wellness gadgets works - S1E1: How do Step Counters work in your fitness watch? - Make it stand out Figure 2 - Source: Modified from Patent US20130191069A1 https://www.chendurs.com/blogs1/category/Technology monthly 0.5 https://www.chendurs.com/blogs2 daily 0.75 2023-05-26 https://www.chendurs.com/blogs2/wireless-charging monthly 0.5 2023-05-26 https://images.squarespace-cdn.com/content/v1/62abc76c40a7fa68c78f5f64/93e87f6c-d591-442e-bc25-c7d41665cc91/Wireless+charging+phone.PNG How Travel & Transport gadgets work? - S2E8: How does Wireless charging work? - Make it stand out Figure 1: Wireless charging in action.
