An emergency location information service (E-LIS) for water-based network devices. The E-LIS includes a server application and server network devices that accepts emergency messages from water-based network devices. The water based network devices comprise one or more sensors or one or more actuators, a wireless connection interface including a wireless low power wide-area ultra-narrowband network interface and a wireless low earth orbit satellite network connection interface and is an automated network device capable of sensing is own environment and automatically sending out the one or more emergency messages or one or more emergency text messages without operator input to an E-LIS server network device when an emergency event occurs on a body of water. The E-LIS server network device provides a current physical geographic location for such water-based network devices and/or users of the water-based network devices in an emergency situation on the body of water such as a river, lake, sea, ocean, etc.

An inflatable device is provided, and contains a body and a mouth. The mouth is positionable in an open position and a sealed position. The body includes a flexible body wall that defines an interior volume. The body defines at least one air flow path from the mouth through the interior volume. The air flow path has an air flow path axis and has a cross-sectional area. The body further includes at least one structural member that applies a force on the flexible body wall transversely outward from the axis so as to urge the flexible body wall towards a transversely expanded state. The body is movable between an axially collapsed state and an axially open state along at least a portion of the air flow path and is urged towards the axially expanded state by a force applied by at least one of: the at least one structural member, and air flow into the body through the mouth when the mouth is held in the open position.

A child water safety bracelet system for alerting parents to their children's entering water includes at least one child bracelet and a parent bracelet. The child bracelet comprises a first housing and a first wristband configured to secure the first housing to a child's wrist. A water sensor, a first CPU, a first battery, and a transmitter are coupled within a first inner cavity of the first housing. The first CPU sends an alarm signal through the transmitter when the water sensor detects water. The parent bracelet comprises a second housing and a second wristband configured to secure the second housing to a parent's wrist. A speaker, a second CPU, a second battery, and a receiver are coupled within a second inner cavity of the second housing. The second CPU activates the speaker to produce the alarm sound when the receiver receives the alarm signal from the transmitter.

A system for self-extrication from a safety harness by the wearer, or during rescue of the wearer, in the event of an emergency including one or more combination cutter and glass break tools mounted onto and around selected portions of the safety harness at predetermined positions for use in cutting the webbing straps of the safety harness in the event of the inoperability of any safety harness release resulting in the severing of the harness at said position and further resulting in the combination tool being freed for use in breaking glass out of a window of a vehicle.

A water floating device that offers support for the head or neck of a user when swimming or practicing water exercises. The floating support device includes a unitary piece body made of a floating and waterproof material. The unitary piece body has a U-shape including a curved central section having a first leg on a first end and a second leg on a second end. The first leg and the second leg project from the curved central section. The first leg and the second leg angle inwardly to one another.

A liquid-ingress control device, comprising a casing having an interior and an exterior, and optionally, a liquid-activated trigger positioned in the casing interior, the casing comprising an exterior liquid entry control surface defined by a perimeter in sealing relationship with an edge of a cap, the cap having an interior cap surface formed to define a cap space between the interior cap surface and the liquid entry control surface; the liquid entry control surface comprising a liquid entry port comprising a tube extending between the exterior and interior of the casing through an aperture formed in the entry control surface, the tube optionally comprising a flange positioned exterior to the casing; the cap comprising at least two flow apertures positioned such that liquid contained within the cap space is capable of egress under gravity from the cap space, independently of the orientation of the device.
