Abstract:

Methods and apparatus (systems) are set forth for generating a ramping output alarm signal. An input alarm driver signal is used to generate a ramp control signal over a predetermined time period, t. A first predetermined output alarm signal is generated at the beginning of time period t; ramping to a second predetermined output alarm signal at the end of time period t, in response to the ramp control signal. Output alarm signals contemplated by the invention may also be stepped (as opposed to ramped), signals. In addition, both audio and visual alarm signals are contemplated by the invention. Both ramping and stepped output alarm signals would, for example, find particular utility in door alarms used in environments where sensitivity to the alarm signal itself is or may be an issue. Such environments include, without limitation, nursing homes and cardiac rehab facilities.
