An apparatus and system utilized in a storm shelter to notify rescue personnel that a person is in the storm shelter and needs assistance to get out. The apparatus comprises a tubular member, a cap at the upper end of the tubular member, a mechanism at the upper end of the tubing to signal rescue personnel and a mechanism to move the tubular member upward. The signaling mechanism is a light source with apertures in the tubing to allow light to emanate outward, reflective material, florescent paint and/or an audible source. The moving mechanism comprises a threaded rod vertically supported by a base with a threaded nut that rotates on the rod to raise the tubular member or it comprises a lifting mechanism that raises the tubular member. The system has an opening in the upper wall of the shelter and a removable plug apparatus that plugs the opening.

Systems and methods for delivering notifications to users in a work environment are provided. A fluid notification device is provided to attach to a wearable article of personal protection equipment (PPE) to be worn by the user. The fluid notification device includes a fluid source component and a fluid flow channel being configured to direct a fluid flow (e.g., a gas flow or a scent) from the fluid source component to the user to deliver perceptible messages. An electronic control unit is functionally connected to the fluid source component to control the delivery of the perceptible message, the control being independent from the operation of the article of PPE.

An in-bed haptic device may include an array of actuation cells. Actuation cells of the array of actuation cells may be configured to actuate (e.g., expand, contract, or otherwise change shape) in a predetermined sequence to provide haptic outputs. The in-bed haptic device may be configured to be placed beneath a user during use, for example between a user and a mattress. The haptic outputs may be provided to help a user relax, to move and/or wake a user, to indicate outputs, alerts, or notifications at the in-bed haptic device or another electronic device, or the like.
