The present disclosure relates generally to the field of electronic communications. More particularly, the present disclosure relates to wearable devices for automatically transmitting a message on detecting the user has fallen.
A person who has fallen may be unable to call for help. For example, the person may be unconscious. Even if conscious, the person may be unable to move, unable to reach a phone, or the like.
In general, in one aspect, an embodiment features a wearable electronic communication device comprising: an accelerometer; a don/doff detector; a transmitter; a processor configured to i) determine whether the wearable electronic communication device has experienced a fall based on information produced by the accelerometer, ii) determine whether the wearable electronic communication device was being worn during the fall based on information produced by the don/doff detector, and iii) cause the transmitter to transmit a message from the wearable electronic communication device responsive to the processor determining both i) the wearable electronic communication device has experienced a fall and ii) the wearable electronic communication device was being worn during the fall.
Embodiments of the wearable electronic communication device can include one or more of the following features. In some embodiments, the message is a first message; and the first message instructs a connected device to transmit a second message. Some embodiments comprise a memory configured to store a phone number; wherein the message instructs a connected device to call the phone number.

At 304, if the processor 108 determines that the wearable electronic communication device 100 has fallen, then at 306 the processor 108 may determine whether the wearable electronic communication device 100 was being worn during the fall based on information produced by the don/doff detector 104. This determination may distinguish a fall of the user from a fall of the wearable electronic communication device 100 alone, for example to identify cases where the wearable electronic communication device 100 has been dropped, thrown, or the like.
In some falls, the wearable electronic communication device 100 may separate from the user during the fall, on impact, or the like. For example, a cyclist wearing a headset may hit a bump in a trail that causes the headset to separate from the cyclist during a resulting fall. Thus determining that the wearable electronic communication device 100 was being worn during the fall includes the case where the wearable electronic communication device 100 was worn only during a portion of the fall.
At 308, if the processor 108 determines that the wearable electronic communication device 100 was being worn during the fall, then at 310 the processor 108 causes the transmitter 106 to transmit a message from the wearable electronic communication device 100. Any message may be used. For example, the message may instruct the smartphone 204 or other connected devices to transmit a message, make a phone call, display specified information, announce the information over a speaker, or the like. The message transmitted by the smartphone 204 may be an email, text message or the like. The message transmitted by the wearable electronic communication device 100 may include one or more phone numbers to be called. Multiple phone numbers may be called in round-robin fashion. The one or more phone numbers may be stored in the memory 110 of the wearable electronic communication device 100, in a memory of the smartphone 204, or the like. The message transmitted by the wearable electronic communication device 100, and the message transmitted by the smartphone 204, may include information such as the duration of the free fall, the severity of the impact, the duration of motionlessness, and the like. These messages may also include information that represents the location of the wearable electronic communication device 100 and/or the smartphone 204. These messages may also include biometric information collected by the biometric sensor 124 of the wearable electronic communication device 100. In embodiments making phone calls, any of the above information may be played as speech during the phone call. In embodiments displaying information, any of the above information may be displayed by a display of the smartphone 204, or the like. In embodiments announcing information, any of the above information may be played as speech over a speaker of the smartphone 204, or the like. Any of the speech may be generated by a speech synthesizer executed by the processor 108 of the wearable electronic communication device 100, by a processor of the smartphone 204, or the like. For example, the smartphone 204 may display and/or announce emergency information such as the name of the user, emergency contact information, a doctor's contact information, drug allergies of the user, medical conditions of the user, and the like, thereby making this information immediately available to a first responder.
In some embodiments, the wearable electronic communication device 100 allows the user to cancel transmission of the message or phone call. If the user is unwilling or unable to cancel transmission of the message or the phone call, the message or phone call is transmitted. In such embodiments, at 312, the processor 108 causes the wearable electronic communication device 100 to prompt the user to cancel transmission of the message or the phone call. For example, the processor 108 may cause the speaker 116 in the wearable electronic communication device 100 to generate an audible message such as “calling 911 in 60 seconds unless the call button is pressed.” This prompt may take any form. For example, the prompt may be an audible message, a visual message generated on a display 118 of the wearable electronic communication device 100 or on a display of the smartphone 204, or the like. At 314, if the user does not cancel transmission of the message, then at 310 the processor 108 causes the transmitter 106 to transmit the message from the wearable electronic communication device 100.
In some embodiments, at 308, if the processor 108 determines that the wearable electronic communication device 100 was not being worn during the fall, then the processor 108 may conduct a self-test of the wearable electronic communication device 100. When the wearable electronic communication device 100 is subsequently donned, the processor 108 may cause the wearable electronic communication device 100 to play a message for the user. For example, the message may state “your device experienced a fall and the self-test confirms it is in complete working condition.”
