Abstract: In measurement requiring application of pressure to a tissue of a living body such as blood pressure measurement, noise due to vibration tends to occur. It is therefore difficult to accurately measure a pulse wave and a blood pressure value, and there is a problem of measuring blood pressure stably. It is also difficult to measure blood pressure in daily life activities or to measure blood pressure at predetermined intervals or continuously in a state where a tonometer is always attached. There is consequently a problem of providing a method of holding a biologic information detecting apparatus. The present invention has been achieved to solve the problems and an object of the invention is to provide an easy-to-wear biologic information detecting apparatus for stably detecting biologic information.

Abstract: To provide a technique which makes it possible to obtain a proper pulse wave signal for high-accuracy blood pressure measurements, thereby saving the trouble of taking measurements repeatedly and reducing a physical burden imposed on the user by cuff pressure.

Abstract: A blood-pressure meter having storing means for storing a blood pressure measurement result, and time measurement means for measuring a time is disclosed. The blood-pressure meter includes: input means for entering behavior history; means for storing the blood pressure measurement result into the storing means while associating the blood pressure measurement result with a time when blood pressure measurement is performed; and means for storing the entered behavior history into the storing means while associating the behavior history with a time corresponding to the behavior history.

Abstract: An living body information collecting apparatus having a shape suitable for being worn in the external auditory meatus of the human body, and having a sensing part for collecting living body information from the external auditory meatus is provided. In addition, a blood-pressure meter is provided, wherein the blood-pressure meter includes: a frame part including a first arm and a second arm that are opposed to each other; a pressure applying part provided on at least one of a side of the first arm opposed to the second arm and a side of the second arm opposed to the first arm; and a detection part for detecting a pulse wave.

Abstract: A neural network circuit and a processing scheme using the neural network circuit in which a synapse calculation for each input value and a corresponding synapse weight of each input value which are expressed by binary bit sequences is carried out by using a sequentially specified bit of the corresponding synapse weight, a summation calculation for sequentially summing synapse calculation results for the input values is carried out to obtain a summation value, a prescribed nonlinear processing is applied to the obtained summation value so as to determine the output value, whether the obtained summation value reached to a saturation region of a transfer characteristic of the prescribed nonlinear processing is judged, the synapse calculation and the summation calculation are controlled to sequentially carry out the synapse calculation from upper bits of the corresponding synapse weight, and to stop the synapse calculation and the summation calculation whenever it is judged that the obtained summation value reac

Abstract: A quantum interference device has semiconductor heterojunctions laminated on a semiconductor substrate for forming a two-dimensional electron gas channel. On the semiconductor heterojunctions are formed a first, a second and a third electrode which, upon the application of a negative voltage, form a depletion region within the semiconductor heterojunctions, thereby making the resulting two-dimensional electron gas channel a quantum wire of a stub structure comprising an entrance and an exit for electron waves, and a stub formed between the entrance and the exit. The second and third electrodes each have a first side substantially parallel to a side of the first electrode. The second and third electrodes also have a second side parallel to each other's second side. On a site near the edge of said stub is provided a fourth electrode for defining the effective length of the stub by a voltage applied thereto.
