International Classification:

G08B 2300

US Classification:

3405734, 340539, 3405731, 455455

Abstract:

There is disclosed a system and method for seizing control of a communications channel in a child monitor of the type comprising a child monitor transmitter and a child monitor base station. The system and method is used in conjunction with a physiological condition monitor that is capable of monitoring the status of a persons physiological conditions such as heartbeat and breathing. When the physiological condition monitor detects that an alarm condition has occurred, it causes a control transmitter to transmit an alarm signal to said child monitor base station. The signal that is transmitted by the control transmitter blocks any signal that is being transmitted to the child monitor base station by the child monitor transmitter. The signal that is transmitted by the control transmitter has (1) a modulation factor that is greater than the modulation factor of the signal transmitted by the child monitor transmitter, or (2) a power level that is greater than the power level of the signal transmitted by the child monitor transmitter.

Abstract:

There is disclosed an apparatus and method for reducing power consumption in physiological condition monitors that use a memory data storage device that operates in a high power mode when data is being written to the memory data storage device and operates in a low power mode when inactive. The apparatus comprises: 1) a controller for receiving incoming data to be written to the memory data storage device; and 2) a first low power buffer coupled to the controller. The controller stores the incoming data in the first low power buffer until a predetermined amount of incoming data has been accumulated in the first low power buffer and transfers the accumulated predetermined amount of incoming data to the memory data storage device in a single data transfer.

US Classification:

381 67, 381 56, 600528, 600586

Abstract:

Physiological condition monitors utilizing very low frequency acoustic signals and signals indicative of body orientation are disclosed. The physiological condition monitors comprise a sensor that is capable of detecting low frequency acoustic signals in the frequency range of one tenth Hertz to thirty Hertz. The sensor comprises a chamber having portions that form a cavity and a low frequency microphone placed within the cavity. An alternate embodiment of the invention comprises a chamber having portions that form a resonant cavity, a microphone mounted in the resonant cavity, and a membrane that covers the resonant cavity. Low frequency acoustic signals that are incident on the membrane cause the membrane to move and amplify the acoustic signals within the resonant cavity. The sensor provides information concerning physiological conditions, such as respiration and cardiac activity. The sensor in a physiological condition monitor does not need to be directly coupled to the skin of the person being monitored.

Abstract:

The present invention introduces systems, as well as methods of operating such systems, within a communication device for evaluating movement of a body relative to an environment. According to an exemplary embodiment, the system comprises a sensor and a processor. The sensor, which is associable with the body, is operable to repeatedly sense accelerative phenomena of the body. The processor, which is associated with the sensor, is operable to process the sensed accelerative phenomena as a function of at least one accelerative event characteristic. The system, and, more particularly, the processor generates state indicia relative the environment, and determines whether the evaluated body movement is within environmental tolerance. In a preferred embodiment, the processor communicates various state indicia to a monitoring controller, preferably using at least one of a wired network and a wireless network. The monitoring controller cooperates with the processor to remotely monitor the body.

Abstract:

There is disclosed a system and method for detecting the onset of an obstructive sleep apnea event before the obstructive sleep apnea event fully develops and before the cessation of breathing occurs. The system comprises one or more microphones capable of detecting breathing sounds within an airway of a person. The microphones generate signals representative of the breathing sounds and send the signals to a controller. The controller identifies at least one signal pattern that is associated with a breathing pattern of the person that occurs at the onset of an obstructive sleep apnea event. The controller may also identify at least one signal pattern that is associated with a partially occluded breathing pattern of the person. The controller identifies the signal patterns by using digital signal processing techniques to analyze the signals representative of breathing sounds. The method involves detecting breathing sounds within an airway of a person, generating signals representative of the breathing sounds, and identifying at least one signal pattern that is associated with a breathing pattern of the person that occurs at the onset of an obstructive sleep apnea event.
