A signal processing device calculates, as a moving speed of each of a plurality of observation targets, a relative speed of each of the targets with respect to a lidar device. A plurality of light pulses having different frequencies from each other are generated, each of the light pulses radiated and then scattered by each of the targets is received, and multiplexed light of each of the scattered light and the laser beam is detected. The signal processing device includes: a Doppler frequency calculating unit to calculate a Doppler frequency in a frequency of each of the scattered light and due to movement of each of the targets from the frequencies of the plurality of generated light pulses and a detection signal of each of the multiplexed light; and a speed calculating unit to calculate a relative speed of each of the targets from each of the Doppler frequency.

To provide a laser distance measuring apparatus which can increase the measurement frequency per unit time by suppressing the increase in the data amount expressing the measurement time, while ensuring the distance measurement precision and the measurable distance. A laser distance measuring apparatus measures, with a time resolution, a light receiving time which is a time from a time point when the laser beam generating unit emits the laser beam to a time point when the light receiving unit outputs the light receiving signal; calculates an object distance which is a distance to the object, based on the measurement result of the light receiving time by the time measuring device; and changes the time resolution of the time measuring device used for calculation of the object distance, based on detection information.

Disclosed is an exhalation gaseous component gauge including, in a palm-sized casing having exhalation taking-in and taking-out slots made on its front and rear sides, a semiconductor gas sensor so placed that the air flowing from one's mouth may pass the sensor, a CPU responsive to the signal from the sensor for determining the quantity of the exhalation gaseous components, and a display for showing the so determined result. The palm-sized casing is so sized and configured as to permit one to have a look at the display while holding the gauge in hand to direct the air from the mouth to the exhalation taking-in slot. Also, disclosed is a cellular phone equipped with an exhalation gaseous component gauge.

A multi-function portable bioelectrical impedance measuring instrument is provided that is easily held in the hand, and has its electrodes and its controls arranged to be easily manipulated. Embodiments include an instrument wherein a pair of electrodes is arranged on the back of a main body of the instrument such that they are both contacted by a user's palm when the main body is held in the palm of the hand. Another pair of electrodes, a set of operating switches, and a display are located on the face (i.e., the front) of the main body such that two fingers of the other hand of the user can touch the electrodes simultaneously and operate the instrument to obtain a body fat occupancy ratio and/or pulse rate based on the impedance measured by the electrodes. A photoelectric detector is also provided on the face of the main body to produce a signal to provide a blood pressure reading or pulse rate. Since the electrodes can be firmly held in contact with the user's skin due to their ergonomic arrangement, the instrument is easily operated and produces accurate monitoring of body fat occupancy ratio, pulse rate, blood pressure, and the like.
