Abstract: An efficiency inference apparatus infers an efficiency of a subject. The efficiency inference apparatus includes a biological information acquisition unit configured to acquire biological information of the subject, and an inference unit configured to infer the efficiency of the subject, based on the biological information. The inference unit may include a trained model to infer the efficiency of the subject from the biological information. The trained model may be trained with a training dataset including the biological information and the efficiency of the subject.

Abstract: An electric bicycle includes a battery, a high voltage electric wire extending from the battery, a motor driven by electricity supplied from the battery, and a reduction gear configured to reduce a speed of output of the motor. The battery is disposed in front of and above the motor. The reduction gear is disposed outside the motor in a vehicle width direction. The high voltage electric wire is disposed in a gap between the reduction gear and the battery in a forward/rearward direction at outer side of the motor in the vehicle width direction.

Abstract: A contents additional services inquiry server for receiving inquiries for additional services provided by a contents center and a third-party contents additional services providing server, wherein a registration request specifies a contents identifier uniquely identifying contents, and requests registration of registration request information including each additional service information regarding service that can be provided with respect to the contents having the contents identifier and provider location information regarding a location of a respective provider of each additional service. Registration request information registered by the contents center and registration request information registered by the third-party contents additional service providing server are separately stored.

Abstract: It is configured such that, on a server for carrying out the inquiry of additional services, in correspondence to a contents identifier embedded in the contents, an information of additional services provided for the contents having that contents identifier and a location information of their providers are stored in advance by separating those operated by the contents center and those operated by the other third parties, and according to that, what sorts of things are there as the additional services provided by the contents center (and the location information of their provider) and what sorts of things are there as information of the additional services provided by the other third parties (and the location information of their providers) are presented in a form that distinguishes them.

Abstract: A video transmission system and method is provided, by which if the arrival of a signal sent from the video receiving side to the sending side is delayed, or if an error is generated in a signal for communicating a receiving error, it is possible to prevent a situation such that no effective reference picture exists in a (picture) memory. In the present method, storing of encoded data into a memory section is controlled based on information indicated by a signal received from the video receiving side, and the control includes determination whether new data are stored, determination of an area for storing data in the memory section, and deletion of data stored in the memory section.
