Abstract: Provided an electrophotographic electro-conductive member that can stably suppress an occurrence of fogging in an electrophotographic image. The member comprises a support having an electro-conductive outer surface, and an electro-conductive layer on the outer surface of the support, the electro-conductive layer having a matrix including a cross-linked product of a first rubber, and domains dispersed in the matrix, the domains each includes a cross-linked product of a second rubber and an electro-conductive particle, at least some of the domains is exposed to the outer surface of the electro-conductive member to constitute protrusions on an outer surface of the member, the outer surface of the electro-conductive member is constituted by the matrix and the domains exposed to the outer surface of the electrophotographic electro-conductive member, the electrophotographic electro-conductive member has an impedance of 1.0×103? or more and 1.0×108? or less, and some of the domains satisfy two specific requirements.

Abstract: In a mental/physical state evaluation system, a motion information acquirer acquires information indicating a motion state of a subject who repeatedly performs a predetermined body motion. A reproducibility evaluator determines a reproducibility evaluation value on the basis of an analysis result regarding the reproducibility of the predetermined body motion. A mental information acquirer acquires information indicating the mental state of the subject. A mental evaluator determines a mental evaluation value on the basis of an analysis result regarding the mental state of the subject. An evaluation value storage stores the reproducibility evaluation value and the mental evaluation value in association with each other. A result outputter outputs information indicating the relevance between the mental evaluation value and the quality of the reproducibility evaluation value.

Abstract: A method and apparatus allows a data tuner to communicate information. An identifier of the frequency used to transmit the data may be transmitted by a control center to a receiver coupled to the data tuner to notify a user to tune to that frequency to receive the data. The data tuner may transmit a frequency identifier to the control center to instruct the control center which frequency to use to broadcast the data. This frequency may be the frequency to which a user is already tuned, or a frequency meeting certain criteria, such as one having reception exceeding a threshold amount. The data tuner may scan header information provided by several frequencies to identify a frequency meeting certain criteria. The data tuner may provide information to a control center using a transmitter coupled to the data tuner in response to requests for information received by the data tuner.
