摘要： In a living body inspection apparatus to inspect RLS (Restless Legs Syndrome), a pulse interval is obtained from a pulse wave signal, thereby performing a frequency analysis of the obtained pulse interval using CDM. From a result of the frequency analysis, the low frequency components ranging from 0.04 to 0.15 Hz and the high frequency components ranging from 0.15 to 0.4 Hz are extracted. A value of low frequency components (LF)/high frequency components (HF) is obtained as an index to which an amendment based on age is applied. It is then determined whether LF/HF is equal to or greater than a predetermined determination value indicating RLS. For example, it is determined whether LF/HF is equal to or greater than 0.65, which suspects RLS. It is determined whether a signal is accurately calculated which indicates an activity of autonomic nerve. A state of RLS is determined using LF/HF.

摘要： A signal-to-noise ratio and measurement precision is increased in electrode units disposed on the left and right sides of a steering wheel. A plurality of electrode units is disposed in the left and right handholds of a steering wheel. The contact impedances of all the electrode units are measured. A pair of left and right electrode units to be used to measure an electrocardiographic signal is designated from among the electrode units whose measured contact impedances are less than or equal to a first threshold. The results of measurement of an electrocardiographic signal by the designated electrode units are added in order to minimize noise. An electrode unit with high contact impedance is used to measure induction noise and remove the induction noise component from the electrocardiographic signal measurement result.

摘要： In a living body inspection apparatus to inspect RLS (Restless Legs Syndrome), a pulse interval is obtained from a pulse wave signal, thereby performing a frequency analysis of the obtained pulse interval using COM. From a result of the frequency analysis, the low frequency components ranging from 0.04 to 0.15 Hz and the high frequency components ranging from 0.15 to 0.4 Hz are extracted. As an index posterior to an age amendment, low frequency components (LF)/high frequency components (HF) is obtained, for instance. It is then determined whether LF/HF is equal to or greater than a predetermined determination value indicating RLS. For example, it is determined whether LF/HF is equal to or greater than 0.65, which suspects RLS. It is determined whether a signal is accurately calculated which indicates an activity of autonomic nerve. A state of RLS is determined using LF/HF.

摘要： In a clinical and physiological abnormality monitoring apparatus, and blood pressure monitoring apparatus detects a blood pressure abnormality and the like of a body by employing a pulse wave signal. A frequency analysis is carried out with respect to a pulse wave signal, while this pulse wave signal corresponds to time sequential data of pulse waves. As a result, both a C-frequency component indicative of a fluctuation component of a base line of the pulse wave signal, and also an A-frequency component representative of the respective pulse waves are acquired. A ratio C/A of power of a peak contained in the C-frequency component with respect to power of a peak contained in the A-frequency component is calculated to determine abnormality of the blood pressure.

摘要： A vital signal detecting apparatus comprises an attachable device to be attached to a finger, a sensor having a light-emitting device and a light-receiving device, and a transmitting circuit for transmitting a signal waveform as a pulse wave from the sensor to a pulse wave monitoring unit. The pulse wave detecting unit also has an attachment detecting circuit for detecting whether or not the attachable device is in an attached state by comparing a signal waveform obtained when the light-emitting device is on with a signal waveform obtained when the light-emitting device is off and an operation control circuit for controlling the operation of the sensor, the transmitting circuit and the attachment detecting circuit. Preferably, the light-transmitting plate is disposed above the light-emitting device and the light-receiving device to pass light therethrough, and the light transmitting plate may be an IR-cut filter capable of blocking light of wavelengths greater than 700 nm.

摘要： A method of executing a branch instruction of jumping to a subroutine in a pipeline control system. The pipeline control system, which utilizes a data bus for instruction read operation and also for data read/write operation, performs at least one stage between an instruction fetching stage and an instruction executing stage. A branch instruction is fetched with a branch address fed through an address bus. The content of a first program counter is temporarily saved in a second program counter. The content of the first program counter is then updated with a new branch address. Following this, the content of the second program counter is saved in a computer memory for use as a return address.

摘要： A biological condition evaluation apparatus determines a symptom of a heart abnormality based on at least one index calculated from a heartbeat interval and/or a pulse interval. The apparatus determines whether it is in a referential period where an amount of change in the index is comparatively small. The apparatus determines whether a plurality of conditions are satisfied or not in an evaluation period set after the referential period. One condition is that an amount of change in the index in the evaluation period is greater than that observed during the referential period. Another condition is that a rate of change in the index is equal to or greater than a predetermined threshold value. The apparatus determines that there is a symptom of a heart abnormality, when both the conditions are satisfied.

摘要： A drowsiness detecting apparatus has a pulse wave sensor and a determination circuit. The sensor is provided to a steering wheel to detect a pulse wave of a vehicle driver gripping the steering wheel. The determination circuit generates a thorax pressure signal indicative of the depth of breathing by envelope-detecting a pulse wave signal of the sensor and determines whether the driver is drowsy by comparing a pattern of the thorax pressure signal with a reference pattern. The display and the buzzer notify the driver and any other passengers in the vehicle of the drowsiness of the driver by a visual indication and buzzing sound, respectively. A body surface motion may be used as a signal that indicates the depth of breathing.
