A hydrogen storage-compression system has a hydrogen storage-compression apparatus and a thermal management system. The apparatus includes a casing and a plurality of storage-compression units mounted within an internal chamber of the casing. Each storage-compression unit includes a container and a metal hydride for hydrogen storage-compression contained within the container. The storage-compression containers are interconnected by a hydrogen gas circuit flow system to a hydrogen inlet and outlet for connection to a hydrogen consumer and a hydrogen source. The thermal management system includes a thermal liquid circuit system and a heat exchanger system. The circuit system includes a closed loop thermal liquid flow circuit, a thermal liquid flowing within the flow circuit, and a pump for pumping the thermal liquid in the flow circuit. The flow circuit is connected to a liquid inlet and outlet of the casing for flowing thermal liquid through the internal chamber around the containers of the storage-compression units for cooling or heating thereof. The flow circuit is coupled to a first heat exchanger thermally coupled to heating source and to a second heat exchanger thermally coupled to a cooling source. The system includes a control system connected to the circuit system for controlling the flow of the thermal liquid in the circuit and through the heat exchangers.

The embodiments herein provide for an oxygen/air cathode that includes metal-organic frameworks and/or hybrids of metal-organic frameworks and carbon networks. The metal-organic-framework-based Li—Ocells are operated in humid Owhere water plays a critical role in improving battery performance. Such embodiments not only improve battery performance but also reduces the cost by cycling the Li—Obatteries in humid oxygen with MOF@CNT hybrid catalysts.

A user terminal and a control method thereof are provided. The control method of a user terminal includes registering a first point, acquiring movement information of the user terminal using a motion sensor when the user terminal moves from the first point to a second point, and providing a user interface (UI) for guiding to the first point on the basis of the movement information if a user command for a return is input. As a result, the user terminal makes it possible to provide the route guidance service to a destination by tracking the moving route of the user terminal when the global positioning system (GPS) signal may not be received.

User terminal and control method thereof

An electronic apparatus according to an exemplary embodiment includes a sensor, a communicator configured to receive a wireless signal, a microphone configured to convert a sound to an electrical signal, and a processor configured to determine a movement of the electronic apparatus based on the signal, determine a location of the electronic apparatus based on a source of the wireless signal, and control a recording operation through the microphone based on the determined location of the electronic apparatus and the status of the electronic apparatus.

Electronic apparatus and method for controlling recording thereof

A device is provided. The device includes an accelerometer configured to measure an acceleration of the device, a controller configured to acquire acceleration data of the device in a first time period and a second time period adjacent to the first time period from the accelerometer, determine a first movement state of a user in the first time period based on the acceleration data corresponding to the first time period, and determine a second movement state of the user in the second time period in consideration of the acceleration data corresponding to the second time period and the determined first movement state, and a display configured to display the first movement state and the second movement state.

Method and apparatus for recognizing user's activity using accelerometer

A video signal processing circuit of a CCD-type color video camera includes a gamma-correcting circuit section, a delay circuit section, a chrominance signal processor and a luminance signal processor. Accordingly, the circuit is configured such that gamma-compensation processing is performed before the separation of the luminance and chrominance signals, and a DC fluctuation due to the gamma-compensation processing is compensated in the luminance signal processor. Thus, horizontal noise caused by the gamma correction can be eliminated, which not only improves picture quality but also enables a reduction in chip size.
