Abstract: A signal processing system and associated methods are disclosed for reliably detecting audible alert signals, such as Temporal-3 (or Code-3) and Temporal-4 (or Code-4) alert signals generated by commercially available smoke, fire, and carbon monoxide detectors. The system and methods are capable of detecting audible alert signals of different intensities in the presence of dynamic background environment (e.g., television programming, music, noise, and the like). The system and methods are capable of detecting audible alert signals generated by far away smoke, fire, and carbon monoxide detectors. The signal processing system and methods may, in some embodiments, be incorporated into a bedside or other unit that generates a supplemental alert signal capable of alerting individuals who might not otherwise respond to the alarm condition, such as individuals who are asleep, children, hearing impaired, or intoxicated.

Abstract: Security systems, methods, and devices for monitoring a region for movement utilize a wireless network detector having a directional antenna and a transmitter for transmitting the detected wireless network signal strength to a computer. Analysis of changes in the signal strength measurements determines the presence of movement requiring a response.

Abstract: A monitoring system and method for monitoring signals from an implantable medical device are disclosed. The monitoring system and method include a monitor configured to detect a radio frequency artifact from the signals of the implantable medical device and circuitry for processing the radio frequency artifact from the signals of the implantable medical device.

Abstract: Methods and systems for waking an individual to an alert condition such as smoke or a fire have greatly improved ability to wake sleeping individuals compared to conventional methods. For example, preferred waking devices include a fluid spray directed toward the head of a bed and the person sleeping in that bed. Used in conjunction with standard digital processing techniques, the systems offer greatly improved reliability and the ability to save lives.

Abstract: Home safety and security are provided using a bedside unit to monitor audible safety and security alarms and send notification signals to the appropriate communication site. A home security system additionally comprises a waking device activated by the bedside unit. A memory device of the unit includes means for determining when the sound received by a microphone of the unit is a security alarm sound or a breathing pattern representing an alarm condition.

Abstract: A health monitoring method and system utilizes a bedside device to monitor breathing patterns and other health measuring signals and communicates these patterns and signals to a medical monitoring station. The medical monitoring service analyzes the signals for health conditions and determines when the signals indicate a medical response is required.

Abstract: A system is disclosed that detects an optical alarm signal, such as a strobe light signal generated by a building alarm system. Upon detecting such a signal, the system generates a supplemental alert signal capable of alerting an individual who might not otherwise respond to the alarm condition, such as an individual who is asleep, hearing impaired, and/or sight impaired. The system may, for example, be implemented as a patient-worn device, a bedside unit, or a personal computer coupled to a light-sensing peripheral device.

Abstract: Home safety and security are provided using a bedside unit to monitor an audible personal security pendant and to send notification signals to the appropriate communication site. Improved reliability is achieved by comparing a stored signal signature to the real time digital pattern representing sounds received using digital acoustic signature recognition technology.

Abstract: Home safety and security are provided using a bedside sound monitoring unit including a microphone, microprocessor, memory and a communications port. The unit utilizes a sound monitoring program for determining when sound received through the microphone of the unit represents a signal from a home security device or a breathing pattern representing an alarm condition. The unit communicates responsive signals to an appropriate site when an alarm condition is determined.

Abstract: Methods useful with conventional personal computers provide automatic response to an identified alarm sound by sending a notification signal via the Internet only when a special sound monitoring program is active.

Abstract: A system and method for analyzing cardiac data acquired from a patient having an implant. The system can acquire non-implant cardiac data and implant cardiac data from the patient. The system can synchronize the non-implant cardiac data and the implant cardiac data and can correlate the non-implant cardiac data with the implant cardiac data to determine a cardiac condition of the patient.

Abstract: Alarm monitors comprising conventional personal computers respond automatically to an identified alarm sound by sending a notification signal via the Internet only when a special sound monitoring program is active.
