Information processing apparatus and method

Abstract: The present disclosure is directed to an information processing apparatus. The information processing apparatus may have a memory configured to store an identification information of an IC tag in association with a communication profile in a table. The information processing apparatus may also have a first communication unit configured to communicate with the IC tag using a first communication function. The information processing apparatus may also have a second communication unit configured to communicate with an external apparatus using a second communication function different from the first communication function. In addition, the information processing apparatus may have a controller, which may be configured to receive identification information from the IC tag through the first communication unit and to establish a connection with the external apparatus through the second communication unit based on the received identification information and the table stored in the memory.

Encoded stream generating apparatus and method, data transmission system and method, and editing system and method

Abstract: A method and apparatus for generating an encoded data stream representing a number of pictures or frames and having a number of layers including a picture layer in which time code information attached to the original data is described or inserted therein for each picture. Such time code information may be inserted into a user data area of the picture layer of the encoded data stream.

Apparatus for optimizing the performance of a power amplifier

Abstract: The performance of a power amplifier used in a signal transmitter, such as in a communication system (e.g., a personal communication system PCS), is optimized by coupling a controllable impedance to the output impedance of the power amplifier. The power output level of the amplifier, which is variable over a range from a minimum level to a maximum level and which is accompanied by a corresponding amplifier output impedance change, is detected, as is the operating power supplied to the amplifier. The controllable impedance that is coupled to the amplifier output is controlled as a function of the detected amplifier power output level and sensed operating power.

Jahn-Teller transition of LiMn 2 O 4 studied by x-ray-absorption spectroscopy

Abstract: The valence states and local structure of ${\mathrm{LiMn}}_{2}{\mathrm{O}}_{4}$ have been investigated in comparison with those of ${\mathrm{ZnMn}}_{2}{\mathrm{O}}_{4}$ and $\ensuremath{\lambda}\ensuremath{-}{\mathrm{MnO}}_{2}$ by using x-ray-absorption spectroscopy on the Mn $K$ edge, in order to study the Jahn-Teller (JT) transition in ${\mathrm{LiMn}}_{2}{\mathrm{O}}_{4}$ at ${T}_{\mathrm{a}}=280\mathrm{K}.$ In the near-edge spectra, a systematic edge shift in accordance with the formal manganese valence was found, confirming the ${\mathrm{Mn}}^{3+}{/\mathrm{M}\mathrm{n}}^{4+}$ mixed states in ${\mathrm{LiMn}}_{2}{\mathrm{O}}_{4}.$ Extended x-ray-absorption fine structure reveals a structural disorder of ${\mathrm{MnO}}_{6}$ octahedra in the cubic ${\mathrm{LiMn}}_{2}{\mathrm{O}}_{4}$ above ${T}_{\mathrm{a}}.$ The local structure is analyzed using a structural model in which ${\mathrm{LiMn}}^{3+}{\mathrm{Mn}}^{4+}{\mathrm{O}}_{4}$ consists of isotropic ${\mathrm{Mn}}^{4+}{\mathrm{O}}_{6}$ octahedra and anisotropic ${\mathrm{Mn}}^{3+}{\mathrm{O}}_{6}$ octahedra distorted uniaxially by the JT effect. The magnitude of the local JT distortion, the ratio of the longer Mn-O distance to the shorter one, is found to be 1.17 at 300 K, which is as large as that of tetragonal ${\mathrm{ZnMn}}_{2}{\mathrm{O}}_{4}$ (1.19). The local structure exhibits no change when the temperature is lowered below ${T}_{\mathrm{a}}.$ These results imply that the low-temperature phase is induced by ordering the local JT distortion.

Telephone apparatus used for computer network telephone system

Abstract: A telephone system including telephone terminals in computer networks connected via servers to transmit data containing at least audio data through the Internet. Upon receipt of information on a source terminal sent via a server, a destination terminal performs operations based on the information. For example, the destination terminal judges whether the source terminal is a previously specified terminal, and connects or does not connect itself to the source terminal in accordance with the judgement.
