Devices, systems, and methods for detecting falls
First Claim
1. A wearable device for detecting falls and transmitting notifications, comprising:
- a first sensor configured to collect acceleration data;
at least one of;
a second sensor configured to collect pressure data;
ora third sensor configured to collect temperature data;
an antenna;
a processor;
a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to;
receive the acceleration data and at least one of the pressure data or the temperature data;
process the acceleration data and at least one of the pressure data or the temperature data to determine real-time changes in body height and body direction of a person;
determine if the person falls based on comparing the determined real-time changes in the body height and the body direction with one or more thresholds;
determine if the person does not get up for a predetermined period of time based on continuous collection of the acceleration data and at least one of the pressure data or the temperature data; and
in response to determining that the person falls and the person does not get up, control the antenna to transmit a signal to one or more hubs, causing the one or more hubs to determine the location of the person and transmit the determined location and a notification of the fall.

Abstract
Devices, systems, and methods are disclosed for detecting falls and transmitting notifications. One embodiment includes a wearable device. The wearable device may include a first sensor configured to collect acceleration data, and at least one of a second sensor configured to collect pressure data or a third sensor configured to collect temperature data. The wearable device may also include an antenna and a processor. The wearable device may also include a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to receive the acceleration data and at least one of the pressure data or the temperature data, process the acceleration data and at least one of the pressure data or the temperature data, and control, when the processor determines that a person falls, the antenna to transmit a signal.

9. A method for determining if a person falls and transmitting notifications, comprising:
-
collecting, by a first sensor of a wearable device, acceleration data; collecting at least one of; pressure data, by a second sensor of the device;
ortemperature data, by a third sensor of the device; receiving, by a processor of the device, the acceleration data and at least one of the pressure data or the temperature data; processing, by the processor, the acceleration data and at least one of the pressure data or the temperature data to determine real-time changes in body height and body direction of a person; determining, by the processor, if the person falls based on comparing the determined real-time changes in the body height and the body direction with one or more thresholds; determining, by the processor, if the person does not get up for a predetermined period of time based on continuous collection of the acceleration data and at least one of the pressure data or the temperature data; and in response to determining that the person falls and the person does not get up, controlling, by the processor, the antenna to transmit a signal to one or more hubs, causing the one or more hubs to determine the location of the person and transmit the determined location and a notification of the fall. - View Dependent Claims (10, 11, 12, 13, 14)

15. A system for determining if a first person falls and transmitting notifications, comprising:
a wearable first device and one or more second devices, wherein the wearable first device is configured to; collect acceleration data; collect at least one of pressure data or temperature data; process the acceleration data and at least one of the pressure data or the temperature data to determine real-time changes in body height and body direction of a person; determine if the person falls based on comparing the determined real-time changes in the body height and the body direction with one or more thresholds; determine if the person does not get up for a predetermined period of time based on continuous collection of the acceleration data and at least one of the pressure data or the temperature data; and in response to determining that the person falls and the person does not get up, transmit a signal to the one or more second devices, causing the one or more second devices to determine the location of the person and transmit the determined location and a notification of the fall to a third device, wherein the second device comprises a hub. - View Dependent Claims (16, 17, 18, 19, 20)
