A method includes receiving sensor data from a sensor associated with a vehicle and determining a likelihood that the vehicle is experiencing an emergency condition based on the sensor data. The method also includes sending an alert indicative of the likelihood, the alert comprising at least a portion of the sensor data.

To collect excretion information indicating a content of excrement in a toilet bowl without having to ask a user of a toilet and prevent flushing of a foreign body other than the excrement, even when the foreign body is present in the toilet bowl.

The information processing system (1) includes an acquisition unit (1a) that acquires excretion information on the basis of imaging data captured by an image capture apparatus installed in such a way as to include, in an image capture range, an excretion range of excrement in a toilet bowl of a toilet, a generation unit (1b) that generates presentation information on the basis of the excretion information, an output unit (1c) that outputs the presentation information, and a washing control unit (1d) that controls a washing function of the toilet bowl. The acquisition unit (1a) acquires information that indicates whether a foreign body being an object other than feces and urine is included in the imaging data as a subject excluding the toilet bowl and washing liquid for the toilet bowl, as at least a part of the excretion information. When information including the foreign body is acquired, the washing control unit (1d) outputs a stop command for stopping the washing function to the toilet bowl side, and the generation unit (1b) generates alert information as at least a part of the presentation information.

An alert system is configured to track conditions for a tracking system. The one or more processors of the alert system are configured to receive data in a payload related to characteristics of tracking devices of the tracking system. The one or more processors are then configured to determine a condition timeframe for each condition for a given alert based on the data in the payload. The given alert requires at least a first condition and a second condition of the plurality of conditions. The one or more processors are configured to perform a query for historical data for the first condition based on a timestamp of the second condition that is prior to the first condition, determine an alert timeframe for the given alert based on the condition timeframes and the historical data, and store the given alert and the alert timeframe in a memory of the alert system.

A plurality of hierarchy information management devices include a first hierarchy information management unit managing first hierarchy information in which information on instruments is represented in a hierarchy structure, and each hierarchy information management device manages the first hierarchy information of a different one of the instruments. A monitoring device includes: a second hierarchy information management unit generating second hierarchy information based on a plurality of different pieces of the first hierarchy information acquired from the hierarchy information management devices, the second hierarchy information being hierarchy information in which the first hierarchy information is connected in a hierarchy structure; a display unit displaying information; and a display processing unit performing a process of switching between a plurality of different monitoring screens for display on the display unit, the different monitoring screens corresponding to different layers in the second hierarchy information and showing the operating state of the monitoring targets.

A method of and device for reducing energy consumption of a motion sensing device by reducing or avoid using function of device's internal GPS system when a predetermined condition is senses. The predetermined condition includes a predetermined state of motion or no-motion sensed. The motion sensing device includes Personal Emergency Response Systems.

In an illustrative embodiment, systems and methods for verifying safety compliance of a worker positioned on a building structure utilize a motion detector module (MDM) for attaching to a wearable safety harness, where the harness has a lifeline attachment feature for connecting the safety harness to a lifeline anchored to the building structure. The MDM may include a motion sensor for detecting movement of the worker and processing circuitry for detecting, from signals provided by the motion sensor, significant movement indicative of the safety harness being properly worn by the worker and/or proper attachment of the safety harness to a lifeline, and translating the significant movements into compliance information. The MDM may include a proximate sensor for detecting contact between the attachment feature on the harness and a fastener on the lifeline for verifying the compliance information.
