FIELD OF THE INVENTION

The present invention relates generally to the field of motion sensing devices and more particularly relates to a motion sensing remote microphone for automatically detecting a state of motionlessness and providing Emergency Alert to others when the wearer of the device has become immobilized or incapacitated.

BACKGROUND OF THE INVENTION

Prompt recovery of an incapacitated or trapped person, such as a Firefighter, or other First Responder requires rapid notification that the person has been trapped or incapacitated, as well as rapid location of the person. Hence it has long been recognized for the need for some sort of a signaling device to be activated when a Firefighter or other First responder becomes trapped or unconscious. There are a variety of motion detectors known in the art to detect movement of the person, and which would be suitable for use as part of the rescue device. Many of these motion

detectors monitor the acceleration of an element thereof and, from this, deduce the state of movement of the device using the electronic sensing devices such as accelerometers and gyroscopes. The accelerometer senses the linear acceleration in multiple directions, from which calculations such as velocity, direction and position can be derived. The Gyroscope senses an angular velocity of the wearer and outputs angular velocity data based on the sensed angular velocity. A multidirectional Accelerometer senses linear acceleration in multiple directions and gravitational orientation. Many Firefighter and other First Responder radios come equipped with an Emergency Alert Button. This button may be found on the radio body only or both the radio body and remote microphone(the remote microphone is attached to the main radio body by a short cord and is usually worn on the chest, shoulder or collar area for easier transmissions). Activation of the Emergency Alert is achieved by depressing one of the provided buttons. The activation may send out an audible distress signal, a Radio Frequency (RF) distress signal, or both. The RF distress signal may be transmitted at a higher wattage and contain specific information about the identity of the sender. A

shortcoming in the Radio Frequency distress systems is found when a Firefighter or other First Responder suddenly becomes incapacitated or unconscious, in such a situation the radio's Emergency Alert button will not be activated. National Fire Protection Association standards require a passive device to be installed in all compliant air packs. These motion sensors, when activated, send out a generic audible alarm. The alarm is akin to a siren that provides a general alert only to those within audible range. The alarm may alert would-be rescuers but fails to identify the sender or be logged or tracked. There is a need for some sort of an RF (radio frequency) signaling device to be activated when a Firefighter or other First Responder becomes trapped or unconscious. The relevant prior art methods, which will deal with motion sensors, are as follows:

US Patent 7,382,249 provides a combined alarm and surveillance system and integrates an existing alarm system with an existing surveillance system such that functions unique to each system are combined in a complementary manner. The existing alarm and surveillance systems are combined via an interface comprising

an array of electric relays. Each relay receives a signal from either the alarm system or the surveillance system and retransmits the signal to the other system in a form that is compatible with the receiving system. The alarm system is configured to communicate alarm status information to the surveillance system, and the surveillance system is configured to communicate control signals to the alarm system, such as an alarm system reset signal. US Patent 7,437,931 details a sensor unit to detect a stillness event, the sensor unit including a gyroscope attached to a monitored person, a micro-controller communicatively coupled to the gyroscope, and a memory communicatively coupled to receive and to store the angular velocity data with a correlated time. The gyroscope senses an angular velocity of the monitored person and outputs angular velocity data based on the sensed angular velocity. The micro-controller receives the angular velocity data and recognizes a quiescence-pattern data in the angular velocity data. US Patent 4,914,422 claims a personal alert safety system (PASS) of the type carried by firefighters, rescuers, and the like. The unit attaches to the firefighters shoulder harness and is characterized by its ability to indicate audibly temperature changes

in 100. degree F increments within the hazardous environment, as well as iack of motion by the firefighter. The activating circuit includes a horn alarm signaling both temperature changes and lack of motion, such that both the firefighter, as well as his colleagues, may be audibly appraised. US Patent Application 20030067385 describes a motion sensor system that has several sensor units. Each sensor unit is freely movable, easily hidden and includes a motion sensor and a wireless radio frequency (RF) transmitter. The motion sensor system further includes a receiver unit, which includes a wireless radio frequency receiver and a device for communicating receipt of a signal to the user. When at least one of the motion sensors of at least one of the sensor units detects motion, the wireless radio frequency transmitter transmits a signal to the radio frequency receiver of the receiver unit. The receiver unit then communicates receipt of the signal to the user. US Patent Application 20090069720 comprises an implantable activity detector can detect metabolic stress levels, which can be normalized, such as to identify times of activities such as walking and running or to identify trends such as a decrease in metabolic activity. The data can be derived from different sources

such as an accelerometer and pedometer. This data can be compared to independently specifiable thresholds, such as to trigger an alert or responsive therapy, or to display one or more trends. The information can also be combined with other congestive heart failure (CHF) indications. The alert can notify the patient or a caregiver, such as via remote monitoring. Metabolic activity data from one or more of the activity detectors can be used to establish a mode! of metabolic stress, to which further activity data can be compared for identifying periods of increased or decreased metabolic stress. US Patent Application 20040066302 provides a Portable accelerometer coupled to a processor and wireless transceiver providing remote monitoring of sensed acceleration. A BLUETOOTH(R)-compatib!e transceiver allows bi-directional communication including transmission of operating parameters and programming as well arm and cancel commands. Networked communications allows remote monitoring and integration with public safety answering point (PSAP). Signal processing at the portable device discerns includes comparison of sensed acceleration with stored profile.

Shortcomings are found in the existing devices claimed in the prior art, when a Firefighter or other First Responder suddenly becomes incapacitated or unconscious. None of the above patents claims a motion sensor that can detect a state of non motion and trigger an alarm in the user's portable radio. Thus, in such a situation of motionlessness, a radio's Emergency Alert button will not be activated. Hence, there is a need for a device and process to sense and capture the user's motionlessness and provide notice of his incapacitation to others as well as aid in quickly and precisely locating the incapacitated person while he is being concealed by smoke or other natural elements or caught in fire or other agents which block direct viewing of the user of the device. The present invention overcomes these and other problems by providing a Motion Sensing Remote Microphone which detects the stillness and orientation of the remote microphone and automatically activates the Emergency Alert as if the wearer pressed the Emergency Alert button themselves. This invention does not require any separate or bulky gear and is incorporated into the remote microphone of the portable radio

of the user. The present invention thus closes a fatal gap in providing the fastest and most far-reaching automatic signaling system for an unconscious or incapacitated Firefighter or other First Responder. The invention is incorporated into the remote microphone in a portable radio carried by such Firefighter or other First Responder, The present invention is thus designed for use in the remote microphone on portable radios, self-powered by portable battery, and intended for personal use by a single individual. When no motion is detected for a preset time interval, an alarm signal is generated. !f the motionlessness of the user is not due to a state of incapacitation or unconsciousness, the alarm can be switched off manually by the user. The activation may send out an audible distress signal, an RF distress signal, or both. The RF distress signal may be transmitted at a higher wattage and contain specific information about the identity of the sender. Further it will be apparent to those skilled in the art that the objects of this invention have been achieved by providing a Solid State Accelerometer interfaced with a Solid State Gyroscope or a multidirectional Solid State Accelerometer in a remote microphone, geared towards portable radios carried by Firefighters and other First

Responders, which is unique in nature unlike existing systems which can be able to apply only for limited purposes. Various changes may be made in and without departing from the concept of the invention. Further, features of some stages disclosed in this application may be employed with features of other stages. Therefore, the scope of the invention is to be determined by the terminology of the following claims and the legal equivalents thereof.
