Use of multiple sensors to determine whether motion of an object is occurring in an area is described. In one aspect, an infrared (IR) sensor can be supplemented with a radar sensor to determine whether the determined motion of an object is not a false positive.

A medical fluid delivery system and apparatus for remote machine updating and control are disclosed. An example medical fluid delivery apparatus includes a processor and a dialysis fluid circuit including at least one dialysis fluid pump. The processor is configured to receive a disinfection input to begin a disinfection procedure and cause the at least one dialysis fluid pump to perform a disinfection procedure on the dialysis fluid circuit using a disinfection fluid. The processor is also configured to, after the disinfection procedure is complete, start a disinfection timer. When a dialysis input is received before the disinfection timer reaches zero, the processor enables a dialysis treatment to be performed. When the disinfection timer reaches zero before the dialysis input is received, the processor prevents the dialysis treatment from being performed until the disinfection procedure is performed again.

System, methods, and other embodiments described herein relate to improving the safety of a vehicle in relation to occurrences of smoke and fire. In one embodiment, a method includes acquiring, from a radar of a subject vehicle, radar data about a passenger cabin of the subject vehicle. The method includes determining a current state of the passenger cabin according to the radar data. The method includes, responsive to identifying that the current state indicates smoke is present within the passenger cabin, controlling the subject vehicle to generate a response to the smoke.

Systems and methods for welding are described. The welding system can include, for example, a welding power source, a welding torch, and a computer. The computer and the welding torch can be operatively coupled to the power source. A first weld is performed and its signature is saved by the computer. It is considered a high quality weld and is selected as a weld reference. A second weld is performed and its signature is saved by the computer. The computer then computes a single weld confidence result for the second weld based on a comparison between the signature data of the second weld and the signature data of the reference weld. A weld fault condition is triggered based on the single weld confidence result which causes the welding system to stop or to modify the welding operation, and/or which causes the welding system to send out communications relating to the triggering of the weld fault condition.

A home occupancy status and information system may be used to track information about human and animal occupants within a structure, and provide information to first responders in the event of an emergency. A rescue beacon may be positioned near an entrance to a home, and when an audible alarm or alarm signal is detected by the beacon it will provide visual alerts and/or audible alerts to attract the attention of a first responder, and will provide information on occupants in the home, such as a number of pets, a number of humans, and other information. A rescue device may also be carried by each pet or other occupant in the house, which may be activated by a wireless signal from a rescue beacon, or by a detected alarm audio/signal. When activated, the rescue device will provide audible and/or visual alerts to aid first responders in locating the occupant.

Various arrangements for handling a potential security situation using a home automation system are presented. A biometric measurement of a user may be received. An alert from a home automation device in wireless communication with the home automation host system may be received. If the biometric measurement is associated with the alert, a security response action may be performed.

A system and method for detecting multiple incidents in a set of flow meter units attached to a set of water consuming units. A plurality of uniquely identified flow meter units are operatively connected to a central control unit. The control unit is programmable to send alerts based on leaking incident status of particular flow meter units so that a responder may receive the alert and timely address the alert. The central control receives and stores data from the multiple flow meter units, including volumetric flow, time, and status and location of each alert. A method of detecting leaking in a building having multiple separate units, each unit having a unit water supply, includes placing a specially configured controller having a flow meter and automatic shut-off valve in each unit of the building. Leak sensors are positioned in water-leak risk areas wherein the controller communicates with both the flow meter and the sensors. A communication is established in between the controller and the sensors. One or more individuals are identified to receive an alert when leakage (or over-pressure conditions) occurs. Water flow is measured with the controller in multiple of the units and using one or more of the sensors. The measurements detect changes when compared to earlier established baseline parameters. An alert is sent to one or more of the individuals (e.g. owner(s), maintenance staff, management) when an abnormal water flow valve is measured.

A facility alert system is provided. The system includes a plurality of remote units, wherein each unit includes a housing having a plurality of controls thereon. Each of the plurality of remote units is in wireless communication with each other via a wireless transceiver disposed within the housing. Each of the plurality of controls illuminates a corresponding indicator light disposed on each housing of the plurality of remote units when actuated. Upon actuation of one of the plurality of controls, an alert signal is transmitted to emergency services via the wireless transceiver. In some embodiments, a vibration motor is disposed within each housing, whereupon actuation of one of the plurality of controls, each vibration motor activates to vibrate each housing in a pattern corresponding to each control.

When activated, the rescue device will provide audible and/or visual alerts to aid first responders in locating the occupant.

The health support system according to a preferred embodiment includes a sensor that outputs an output signal corresponding to a specific component in urine, a transmitter connected to the sensor, and a user terminal carried by the user. The user terminal includes a storage unit that stores an identifier corresponding to the user, a wireless receiving unit that receives a wireless signal from the transmitter, an output unit that outputs the data to an analysis system that analyzes the health state of the user based on a specific component indicated by the data when the identifier indicated by the wireless signal matches the identifier stored in the storage unit, and an acquisition unit that acquires information corresponding to the results of the analysis of the analysis system.
