Abstract: A condition monitoring device for monitoring conditions related to a user. A monitor main unit includes a connection structure for detachably attachment to a first sensor unit. The first sensor unit includes a first connector mated with the connection structure of the monitor main unit and a second connector detachably attachable to a second sensor unit. Data associated with the monitored condition detected by the first sensor unit is provided to the monitor main unit via the first connector and the connection structure. Data associated with a monitored condition detected by the second sensor unit is provided to the monitor main unit via the second connector, the first sensor unit, the first connector, and the connection structure.

Abstract: A comfortable environment providing apparatus for controlling at least one comfortable environment creation devices that creates a comfortable environment to provide a user with a comfortable environment. The comfortable environment providing apparatus includes a sensor unit for monitoring a condition related to the user and outputting data representing the monitored condition when carried by the user. A control circuit executes control of the at least one comfortable environment creation devices so that the monitored data approaches comfortable environment reference data quantitatively or numerically indicating a comfortable environment.

Abstract: A condition improvement advisor for monitoring a condition related to the user and improving the monitored condition. The condition improvement advisor includes a sensor unit for detecting the monitored condition and outputting data representing the user's present state when carried by the user. A present state determination circuit determines from the data representing the user's present state whether or not the user's present state should be improved. When determining that the user's present state should be improved, the present state determination circuit generates advice indicating an item that would improve the present state. An output device outputs the advice generated by the present state determination circuit in a form understandable to a human.
