In a display assistant device, a speaker is mounted in a waveguide structure which is at least partially disposed beneath a display screen. The waveguide structure is mounted in an exterior housing which includes speaker grills distributed on a plurality of surfaces of the exterior housing, permitting sound waves from the speaker to be projected outside the exterior housing. A cover structure is disposed on top of the waveguide structure to conceal the waveguide structure and speaker within the exterior housing. The cover structure has a tilted bottom surface configured to be suspended above the waveguide structure and to be separated by a first space. Sound waves projected from an upper portion of the speaker are reflected by the tilted bottom surface and are guided through the first space to exit the device from a speaker grill portion located on a rear side of the exterior housing.

A wireless communication system is mounted on a moving body, and includes a wireless communication unit, a terminal identification (ID) reader, an operation receiver, a moving body state detector, a communication permission list, and a controller. The wireless communication unit transmits and receives information to and from the wireless terminal. The terminal ID reader reads, from the wireless terminal, ID information that identifies the wireless terminal. The operation receiver receives a specific operation from a user. The moving body state detector detects an operation state of the moving body. The communication permission list stores the ID information of a wireless terminal that is permitted to communicate with the wireless communication unit. When the operation receiver receives the operation from the user and the moving body state detector detects that the moving body is in a preset operation state, the controller adds, in the communication permission list, the ID information of the wireless terminal read by the terminal ID reader.

An image capturing apparatus capable of guaranteeing the authenticity of contents while reducing the calculation load of a hash value of an image file. The image capturing apparatus generates an image file, and performs processing for reducing a file size of the image file. A hash value generation section calculates a hash value by applying a hash function to the processed image file. Reduction processing information indicating a method of reducing the file size is generated, and the image file, the hash value, and the reduction processing information are transmitted in a state associated with each other, to a management system that registers data associated with the image file including the hash value in a blockchain.

Image processing techniques can be used to determine whether a person has installed an unauthorized device on or in a kiosk. For example, an image processing server can determine whether a person's hand(s) are engaging in abnormal behavior by obtaining recorded images of the person's hand(s) that extend towards the kiosk to perform an action, and by comparing the information in the recorded images with a set of previously known information about other persons' hands that are similarly extended towards the kiosk.
