Air pressure mats are highly sensitive and detect the change in pressure as a patient gets out of a chair or bed. Frequency Precision uses patented Airlert technology invented by company founder Doug Dwyer.
A traditional 'contact' type pressure mat consists of two pieces of foil separated by a layer of foam. When a person steps onto the mat, the two pieces of foil touch each other through the holes in the foam, triggering the sensor. If used in a bed or chair, when a person gets up, the opposite happens - the two pieces of foil lose contact, also triggering the sensor.
Unfortunately, there are several limitations with this traditional design:
The Airlert technology used by Frequency Precision represents a major improvement over traditional designs. An Airlert pressure mat is based on the same principle as a self-inflating camping mat: it contains nothing except for a thick layer of foam, which has many tiny air pockets within it. The foam is covered in a durable, flame retardant airtight cover. A rubber tube connects the pressure mat to a sensor box, powered by 2 x AA batteries which can last around a year without needing to be changed. The design is simple and reliable as there are no electronics or wires inside the mat.
The foam is naturally self-inflating so when pressure is removed it will expand to resume its original shape. This sucks in air which is measured by the control box and if a certain pattern of pressure (such as occurs if a person gets out of the bed or chair) is detected, the sensor will create an alert.
