1. A water alarm device for attachment to a user in a body of water, the device comprising:
- a buoyant alarm unit including a water sensor and an attachment member connected to the buoyant alarm unit and configured to attach the buoyant alarm unit to the user, the water sensor being configured to sense if a sensing portion of the alarm unit is in contact with water, wherein the buoyant alarm unit and the attachment member are configured so that the buoyant alarm unit floats at a surface of the water such that the sensing portion is generally not in contact with the water when the user is swimming at the surface of the water, and submersion of the sensing portion of the buoyant alarm unit for a predetermined time indicates that the user has an increased risk of drowning;
a timer in communication with the water sensor and configured to determine a duration of water contact with the sensing portion of the alarm unit; and
wherein the buoyant alarm unit is configured to be submerged when the user is at an increased risk of drowning and to activate an alarm when the duration of water contact is greater than the predetermined time.

Abstract
A water alarm device for releaseable attachment to a user in a body of water includes a buoyant alarm unit having a water sensor. The water sensor is configured to sense if a sensing portion of the alarm unit is in contact with water. A timer is in communication with the water sensor and is configured to determine a duration of water contact with the sensing portion of the alarm unit. The alarm unit is configured to travel to a surface of the body of water and activate an alarm when the duration of water contact is greater than a predetermined time.

17. A water alarm system comprising:
-
an alarm base station configured to provide an audible alarm when an alarm activation signal is received; a water alarm device comprising; a buoyant alarm unit having a water sensor and an attachment member connected to the buoyant alarm unit and configured to attach the buoyant alarm unit to the user, the water sensor being configured to sense if a sensing portion of the alarm unit is in contact with water, wherein the buoyant alarm unit and the attachment member are configured so that the buoyant alarm unit floats at a surface of the water such that the sensing portion is generally not in contact with the water when the user is swimming at the surface of the water, and submersion of the sensing portion of the buoyant alarm unit for a predetermined time indicates that the user has an increased risk of drowning; and a timer in communication with the water sensor and configured to determine a duration of water contact with the sensing portion of the alarm unit; wherein the buoyant alarm unit is configured to be submerged when the user is at an increased risk of drowning and to transmit the alarm activation signal to the alarm base station when the duration of water contact is greater than the predetermined time. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 31, 34)

28. A method for reducing a risk of drowning in a user in a body of water, the method comprising:
-
attaching a buoyant alarm unit to the user with an attachment member connected to the buoyant alarm unit, the buoyant alarm unit having a water sensor thereon, wherein the buoyant alarm unit and the attachment member are configured so that the buoyant alarm unit floats at a surface of the water such that the sensing portion is generally not in contact with the water when the user is swimming at the surface of the water, and submersion of the sensing portion of the buoyant alarm unit for a predetermined time indicates that the user has an increased risk of drowning; sensing with the water sensor if a sensing portion of the alarm unit is in contact with water, wherein the buoyant alarm unit is configured to be submerged when the user is at an increased risk of drowning; determining a duration of water contact with the sensing portion of the alarm unit; and activating an alarm with the alarm unit when the duration of water contact is greater than the predetermined time. - View Dependent Claims (29, 32, 35)
