Abstract: A data transfer system has one or more mobile stations each wearable by a living being for transmitting signals containing physiological information of the living being in response to a start command, and a base station for transmitting the start command to instruct the mobile stations to transmit the signals and thereafter receiving the signals containing the physiological information from the mobile stations. Thus, the mobile stations consume a small amount of power because they only transmit information when requested to do so. A remote computer is connected to the base station for determining a status of the living beings by receiving the physiological information from the base station and analyzing the physiological information.

Abstract: Information of oscillation frequency of a laser beam source in a predetermined range including usable oscillation frequency that takes into consideration an output quality of the laser beam source, such as information on a relationship between oscillation frequency and output quality, is stored in a memory. Then, when the laser beam source is controlled, based on the information stored in the memory, a particular frequency range where the output quality of the laser beam source deteriorates or becomes good is specified, and a decision is made whether or not oscillation frequency f, which is going be used, is within the particular frequency range. Then, according to the results, the oscillation frequency is set, avoiding a frequency range where the output quality deteriorates or within a frequency range where the output quality becomes good according to the result. Thus, a laser beam source whose output quality is always good can be used.

Abstract: A data communication system has a first communication equipment having a first transmitter, a first receiver, and a first controller. A second communication equipment has a second transmitter, a second receiver, and a second controller. The first transmitter transmits a first signal to the second receiver. The first receiver receives a second signal transmitted from the second transmitter. The second signal indicates whether or not the second receiver received the first signal or indicates a condition in which the second receiver received the first signal. The first controller controls the first transmitter to reduce its transmitting power either until when the second signal indicates that the condition of the reception of the first signal received by the second communication equipment is poor or until when the first receiver does not receive any signal from the second transmitter. The second controller generates the second signal in accordance with the first signal.
