Abstract: A server information handling system is secured by a bezel that couples to an access location, such as an air vent at a front or rear face of a housing. The bezel includes a security structure having a lock and configured to couple directly at the front face or with a bezel extension at the rear face so that the server information handling system can use the same bezel with both a front face or rear face rack mount. The bezel has a lock integrated with the security structure, an air filter that fits over the security structure to filter air flowing into the housing, and a filter brace that captures the air filter by coupling to the security structure over the air filter. The filter brace attaches and detaches at the security structure when the security structure locks a server information handling system housing so that the air filter can be changed while the housing remains secure.

Abstract: The present disclosure provides a radar object recognition method, which includes steps as follows. The radar image generation is performed on radar data to generate a radar image; the radar image is inputted into an object recognition model, so that the object recognition model outputs a recognition result; the post-process is performed on the recognition result to eliminate recognition errors from the recognition result.

Abstract: A package structure including a carrier, a photonic device, a supporting frame, and an encapsulant is provided. The photonic device is disposed on the carrier. The supporting frame is disposed on the carrier and surrounds the photonic device. The encapsulant covers the supporting frame and surrounds the photonic device.

Abstract: A health care device and a health care method are illustrated, the health care method is used to arrange the health care device at a predetermined location in front of a belly button of a user with a predetermined distance, and to emit the low-frequency wave with a predetermined frequency to the belly button by using a low-frequency wave emitter. The health care device is formed by the low-frequency wave emitter and a cone/pyramid part. The predetermined frequency is 1.27 Hz to 1.81 Hz, and the predetermined distance is 5 cm to 8 cm. The above health care device and method can increase contents of active T cells and B cells in blood and increase an ability of NK cell strains for poisoning cancer cell strains (K562). In short, the above health care device and method have health benefits without a risk of excessive energy causing harm.
