A system, apparatus, and method of providing an alert when an infant or child is in a child safety seat in a vehicle. Exemplary embodiments can include a pressure sensor and a transmitted signal, such as a continuously transmitted signal, when an infant or child is in a child safety seat and other conditions are met. In some examples, if a continuously transmitted signal is broken or otherwise fails to transmit, an alert may be provided. The alert may be provided through any of a variety of data transmission protocols to any of a variety of devices or locations, for example a mobile phone, smart phone, dedicated alert device, or emergency call center, depending on desired conditions.

A motion sensing device includes an attachment mechanism configured to quickly and easily attach to an object, a motion detector configured to detect motion of the object, a short-range wireless communication component configured to communicate motion information related to the detected motion, and an indicator.

A control device includes an interface module configured to supply electric power to a field device installed in a plant, an application executer configured to output a reset signal for resetting the field device, and a converter configured to convert the reset signal, which has been output from the application executer, into a format which is suitable for the interface module.
