Abstract: A biological information measurement device according to the present invention detects a signal expressing biological information from a fingertip using an internal sensor (S1). A first perfusion index and first biological information aside from the first perfusion index are obtained from the signal detected by the internal sensor (S2, S3). It is determined whether or not the first perfusion index is greater than or equal to a first threshold (S4). When the first perfusion index is greater than or equal to the first threshold, the first biological information is permitted to be displayed in a display unit (S5). However, when the first perfusion index is less than the first threshold, a notification is made indicating that an external sensor that is lighter than a main body, is an entity separate from the main body, and is communicably connected to the main body is to be used (S6).

Abstract: A motorcycle includes an engine configured to expel an exhaust from combustion chambers of cylinders in a cylinder head through exhaust ports. Each of the cylinders is provided with a recessed portion provided in an exhaust passage wall surface in a central portion of an exhaust passage of a corresponding exhaust port. This makes it possible to maintain flow rate and flow velocity of the exhaust gas, and to decrease exhaust loss. As a result, it is possible to increase engine torque by use of a simple structure. In addition, no restriction is imposed on the layout of parts around the engine, because the recessed portions are provided in the exhaust ports.

Abstract: A portable electrocardiograph having a display function and method is disclosed. In measuring an electrocardiographic waveform, an electrocardiograph (1) is held in position by a grip including a negative electrode (14) while simultaneously pressing a contact section including a positive electrode (16) against an electrode contact portion other than the right hand of the subject. The measurement result is displayed on a display unit (10) during the measurement operation. The measurement method is divided into the induction mode I in which the contact section including the positive electrode (16) is pressed against the subject's left hand, and the induction mode II in which the contact section including the positive electrode (16) is pressed against the subject's lower left abdomen. In induction mode I, the measurement result is displayed horizontally on the display (10), while in the measurement in mode II, the measurement result is displayed vertically.

Abstract: A portable electrocardiograph includes an electrode unit brought into contact with a living body of a subject, a processing circuit measuring an electrical signal detected by the electrode unit with being in contact with the living body as an electrocardiographic waveform, and a display unit displaying a measurement result of the electrocardiographic waveform. In measurement, when a CPU of the processing circuit receives the electrical signal of the electrocardiographic waveform via the electrode unit, an amplifier circuit, a filter circuit, and an A/D converter, the CPU detects whether or not baseline fluctuation in the electrocardiographic waveform deviates from a predetermined range in which analysis of the waveform is acceptable, based on the received electrical signal. If the CPU detects deviation from the predetermined range, it displays such information on the display unit as a measurement result.

Abstract: A portable electrocardiograph includes a first electrode on an outer surface of a device main body and a second electrode drawn outside the device main body via a connection cable. The first electrode and the second electrode are brought into contact with a body surface. Then, a potential difference between the first and second electrodes is measured in order to measure an electrocardiographic waveform. In this manner, a noise caused by a myoelectric potential produced in muscles other than cardiac muscle is not superposed on the electrocardiographic waveform, and the electrocardiographic waveform can precisely be measured in a stable manner.
