Abstract: A fan control system for use in a server system is disclosed. The fan control system includes a first monitoring and protection chip, a second monitoring and protection chip, a switch, a plurality of fans and a complex programmable logic device (CPLD). In a shutdown state of the server system, the switch is switched under control of the CPLD so that the fans are connected to the second monitoring and protection chip, receive standby power therefrom and run at a standby power level. When the server system is switched to a working state, the switch is switched under control of the CPLD so that the fans are connected to the first monitoring and protection chip, receive operating power therefrom and run at a higher working power level. This design can address different heat dissipation needs of various applications.

Abstract: An acoustic sensor attached to a medical patient can non-invasively detect acoustic vibrations indicative of physiological parameters of the medical patient and produce an acoustic signal corresponding to the acoustic vibrations. The acoustic signal can be integrated one or more times with respect to time, and a physiological monitoring system can determine pulse or respiration parameters based on the integrated acoustic signal. The physiological monitoring system can, for instance, estimate a pulse rate according to pulses in the integrated acoustic signal and a respiration rate according to a modulation of the integrated acoustic signal, among other parameters. Further, the physiological monitoring system can compare the integrated acoustic signal or parameters determined based on the integrated acoustic signal with other signals or parameters to activate alarms.

Abstract: In a robot control system, the operation of a mobile robot that moves autonomously inside a facility is controlled based at least on an image captured by a photographing device that photographs a blind area located at a blind angle to the mobile robot. When entry of the mobile robot into a predetermined area corresponding to the blind area is detected, the amount of information obtainable from an image captured by the photographing device is increased.
