The processor may be configured to (i) control reception of an alarm message from one or more of the call light boxes in response to an event, (ii) illuminate a hall indicator in response to reception of the alarm message, (iii) receive a cancellation message from at least one of (a) one or more of the call light boxes and (b) the annunciator that cancels the event, and (iv) extinguish the hall indicator in response to cancellation of the event. The hall indicator may change color over time until the event is canceled.

An example portable heating device includes a container, one or more heating elements, an electronic device, one or more temperature sensors, a controller, a power supply, and a power supply controller. The one or more heating elements are in thermal contact with the container. The electronic device is configured to receive a user input selecting a target temperature to heat a substance in the container to and to display the target temperature. The controller is configured to cause the one or more heating elements to heat the substance to the target temperature in response to determining the current temperature of the substance measured by the one or more temperature sensors is less than the target temperature. The power supply is configured to provide power to the one or more heating elements, the electronic device, the one or more temperature sensors, and the controller.

Techniques for configuring a vehicle based on user data. A vehicle can receive user data indicative of an environment setting associated with the vehicle, such as a temperature setting, an active safety setting, a suspension setting, etc. The vehicle can use the user data to determine a seat for a user associated with the user data. The user data can include request data and seat preference data. The vehicle can generate and send a seat assignment message to a device associated with the user data. The vehicle system can be configured based on the environment setting associated with the vehicle. The vehicle system can further output an indication for guiding the user to the vehicle seat. In some examples, the indication can be emitted via lights embedded in a headliner of the vehicle.

A medical fluid delivery system and device for remote machine updating and control are disclosed. An example medical fluid delivery device includes a processor and a dialysis fluid circuit including at least one dialysis fluid pump. The processor determines a self-test needs to be performed and transmits, to a server via a network, a message indicating (i) that the self-test is ready to be performed or (ii) a time to perform the self-test. The processor receives, from the server via the network, a command message to perform the self-test. The processor then causes the at least one dialysis fluid pump to perform the self-test.

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 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.

A gas detection device is disclosed. A gas detection device according to an embodiment of the present invention includes a case in which a plurality of grooves are formed in a circumferential surface, an inlet which is coupled to a first groove among the grooves and through which air is introduced into the case, a power button which is coupled to a second groove among the grooves and turns a power source on or off, a gas detector which is provided in the case and detects a gas contained in the introduced air, a light unit which is coupled to a third groove among the grooves and informs a state in which the power source is turned on or off and whether the gas is detected, a battery which supplies power, a beep generator which generates a beep when a gas detection signal is received from the gas detector, and a power switch operated by the power button to turn on or off so as to supply the power from the battery, wherein one or more of the inlet, the power button, and the light unit are coupled to the grooves in a recessed form, the battery, the beep generator, and the power switch are provided inside the case, and the case is formed in a small spherical shape which is carried in a palm of an operator and moved by the operator.

A method for monitoring a potential hazard at an unoccupied transport unit and issuing a notification in response to detecting the potential hazard is provided. The method includes monitoring for the potential hazard at the unoccupied transport unit. The method also includes determining whether there is someone is in close proximity to the unoccupied transport unit upon determining the potential hazard. Also, the method includes providing a local notification of the potential hazard when it is determined that there is someone is in close proximity to the unoccupied transport unit and not providing the local notification of the potential hazard when it is determined that there is no one in close proximity to the unoccupied transport unit.

A medical fluid delivery system in one embodiment includes: a first medical fluid delivery machine configured to generate a first message for remote transmission to a first patient or caregiver indicating (i) that the first medical fluid delivery machine is ready to perform a task or (ii) a preprogrammed time for the first medical fluid delivery machine to perform a task; and a second medical fluid delivery machine configured to generate a second message for remote transmission to a second patient or caregiver indicating (i) that the second medical fluid delivery machine is ready to perform a task or (ii) a preprogrammed time for the second medical fluid delivery machine to perform a task.

Hospital-acquired infections or nosocomial infections are decreased when medical personal observe a hand washing protocol. A method is disclosed for encouraging adherence to a hand washing protocol when entering and exiting rooms of patients. A carried device, or badge, receives a first signal when proximate to a wash station. A first indicator on the badge displays indicates that that the wearer has visited the wash station. The badge receives a second signal when inside a patient's room, i.e., when visiting a first contaminated area. The badge may receive a third signal when entering a second contaminated area. A second indicator on the badge alerts the wearer when a countdown expires after washing, of failure to visit the wash station before the first room visit, or of failure to visit the wash station between room visits. Reporting data may be uploaded to a database.
