Abstract: Aspects of the disclosure provide a frame processor for processing frames with aliasing artifacts. For example, the frame processor can include a super-resolution (SR) and anti-aliasing (AA) engine and an attention reference frame generator coupled to the SR and AA engine. The SR and AA engine can be configured to enhance resolution and remove aliasing artifacts of a frame to generate a first high-resolution frame with aliasing artifacts and a second high-resolution frame with aliasing artifacts removed. The attention reference frame generator can be configured to generate an attention reference frame based on the first high-resolution frame and the second high-resolution frame.

Abstract: In a file sharing system, a key manager unit realizes a correspondence between the first user identifier and the first public key in response to a registration request of the first user, generates a first key material for encrypting the first file into a first encrypted file, and generates a first credential according to the first user identifier, the first file identifier, the first public key and the first key material after receiving an access-right claim request to the first file from the first user. A file storage unit stores the first encrypted file and the first credential. The first user uses the first user identifier, the first file identifier and the first private key to retrieve the first key material out of the first credential, and uses the first key material to decrypt the first encrypted file into the first file.

Abstract: A water inlet/outlet reversible water heater includes a heating tube including a tube body made from a high temperature resistant insulation material and a heating wire surrounding the tube body, a casing holding the heating tube on the inside and having a water hole in each of two opposite ends thereof for letting water pass through the axial center hole of the tube body. When water is delivered through the axial center hole of the tube body of the heating tube through an internal control, it is heated by the heating wire subject to the control of an external circuit control device, preventing the internal circuitry from thermal damage.

Abstract: A water heater includes a water heater main unit and a control circuit unit connected in parallel. The control circuit unit includes a circuit board carrying a water permeation safety control device and a tilt angle sensor switch. The water permeation safety control device includes an auto power-off safety device for automatically interrupts electrical current if water is permeated in the control circuit unit. If the water heater is installed in a wrong direction or tilted over a predetermined angle, the angle sensor switch automatically switches off the circuit.
