CPC Class H04N

Disclosed are methods and apparatuses for providing notifications in a communication network of a plurality of Internet of Things (IoT) devices. In an aspect, a supervisor device in the communication network detects a notification directed to a wireless mobile device in the communication network and sends at least one instruction to at least a first IoT device of the plurality of IoT devices to reduce an operating volume or suspend operation of the first IoT device. The first IoT device receives the at least one instruction from the supervisor device and reduces the operating volume of the IoT device or suspends the operation of the IoT device in response to the at least one instruction.

There is provided a control device, a control method, and a program through which it is possible to implement a more suitable imaging environment even under a situation in which auxiliary light is emitted from a plurality of light sources, the control device including: an acquisition unit configured to acquire a light emission state of a first light source; and a control unit configured to control an operation of light emission of a second light source that is different from the first light source according to the acquired light emission state of the first light source.

A conventional up/down Gray code counter has both a logic circuit section for up counting and a logic circuit section for down counting, and thus has a large circuit scale. To overcome this inconvenience, an up/down Gray code counter of the invention has a one-way Gray code counter that can count only in one, up or down, direction and a highest bit selecting circuit that receives the highest bit of the data output from the one-way Gray code counter and that then outputs the bit selectively either intact or after inverting it.
