1. A system comprising:
- a fall sensing device;
an apparatus responsive to an ambient or environmental condition and to an output from the device to produce an indicator of either the ambient or environmental condition, or a fall; and
an alarm generating unit, responsive to the apparatus, to generate at least a fall indicating indicium,where the fall sensing device includes at least one of an acceleration sensor, or a position sensor, andwhere the fall sensing device or the apparatus increases detection of a serious fall event by temporarily changing selected motion detection parameters after the fall sensing device or the apparatus detect an acceleration beyond a certain threshold, andwhere, during a period of altered motion parameters after a possible fall, the apparatus generates an alarm signal in the absence of the fall sensing device or the apparatus detecting motion for a predetermined period of time.

Abstract
A fall indicating alarm system includes one or more fall sensors and at least one gas sensor coupled to a displaced alarm system which, responsive to an output from a fall sensor, generates an audible or visual alarm indicator. Both local and displaced alarm indicators can be generated.

14. An apparatus comprising:
-
a fall sensor; a gas sensor; and control circuits, responsive to outputs from at least the fall sensor to detect the presence of a fall, and generate a fall related indicium, where the fall sensor or the control circuits increase detection of a serious fall event by temporarily changing selected motion detection parameters after the fall sensor or the control circuits detect a possible fall event, and where, during a period of altered motion parameters after the possible fall event, the control circuits generate the fall related indicium in the absence of the fall sensor or the control circuits detecting motion for a predetermined period of time. - View Dependent Claims (15, 16, 17, 18)
