A millimeter wave radar apparatus determining a fall posture is applied to a human body. The millimeter wave radar apparatus includes a microprocessor and a millimeter wave radar. The millimeter wave radar is electrically connected to the microprocessor. The millimeter wave radar is configured to transmit a radar wave to the human body. The millimeter wave radar is configured to receive a reflected radar wave reflected from the human body based on the radar wave. The microprocessor is configured to obtain a point cloud information based on the reflected radar wave. The microprocessor is configured to utilize the point cloud information to determine whether the human body is in the fall posture.

There is provided a method and apparatus for detecting a fall event of the user. In particular, the method includes collecting data associated with activities of the user from a plurality of sensors and distributing the collected data to data sub-windows using signal windowing and segmentation, the data sub-windows indicative of a pre-fall moment, a fall moment, and a post-fall moment. The method further includes extracting a plurality of features from one or more of the data sub-windows and determining whether the event is a fall event at least in part based on the extracted features. The determination of whether the event is a fall event can further be determined by applied support vector machine (SVM) technique. The developed machine learning based methods may be substantially optimum in terms of a trade-off between accuracy and complexity of the evaluation. The method further includes multiple rejection filters in order to aid with the prevention of false alarms due to fall-like activities of daily living (ADLs). The method further includes a personalization process to update the machine learning based methods associated with each user.

One aspect of the apparatus comprising, a sensor configured to acquire a biological signal of a user, and a controller configured to, determine whether the biological signal is continuously outside a predetermined range for a first time period, after determining that the biological signal has been continuously outside the predetermined range for the first time period, then determine whether the biological signal is inside the predetermined range, and activate an alarm if the controller has determined that (i) the biological signal has been outside the predetermined range for the first time period, and (ii) the biological signal has been continuously inside the predetermined range for a second time period, the second time period being longer than the first time period.

A medical apparatus, method, or storage medium to perform monitoring a sensor of the medical apparatus to obtain a sensor reading, performing impact detection based on the sensor reading, generating an impact profile based on the impact detection, characterizing the impact detection, and responding to the impact detection.

A wearable device and a system that includes the wearable device is provided. The wearable device includes at least one sensor configured to sense a characteristic of a user, a communication interface configured to obtain a first identifier of a vehicle or equipment, and a controller. The controller is configured to monitor the user based on the first identifier or send the first identifier to a monitoring system; determine whether there is a harm possibly occurring to the user of the wearable device based on at least one output from the at least one sensor, or send the at least one output to the monitoring system via the communication interface; and output, after the harm is determined to be possibly occurring, an alarm based on receiving confirmation from the user, or based on not receiving any confirmation from the user within a predetermined amount of time.

Apparatus and associated methods relate to a smart hook, a safety harness module, and associated electronic components that detect a safety state of a user by monitoring various parameters at the smart hook and safety harness module and determining whether the user is using proper safety protocol at extreme heights and/or whether the user has experienced a height-related accident. In an illustrative example, the user may don a safety harness that may include a module that contains sensors that monitor an acceleration/velocity/position of the user and/or ambient air pressure around the user. The module may receive wireless signals from at least one rebar hook having sensors that monitor the acceleration/velocity/position and gate position of the rebar hooks. A controller included with the safety harness module may use these sensors to advantageously determine the safety state of the user and generate alert/warning signals.

A mount for a device configured to monitor the movements or other activities of patient. Aspects include a monitoring unit and base, where the base may further include a pad with one or more pins extending into the base. The pad may be positioned inside a garment worn by a patient, the pins passing through the garment and electrically connecting to circuits in the fabric of the garment (e.g. a sock worn by the patient). The circuits may include sensors which are response to changes in pressure caused by patient movement. Output from the sensors may be carried by the circuits in the garment to the pins in the pad, and from there through the garment and into the base and the monitoring unit for processing and reporting to caregivers as needed.

A garment is intended to identify a danger situation for the user and react. The garment comprises an emergency device provided with sensors. Furthermore, the emergency device comprises an electronic processing unit and a supervisor and communication unit. The supervisor and communication unit, after being informed of the danger situation by the electronic processing unit, monitors the user by means of the sensors and assesses the level of user activity in order to decide or not to call for further assistance.

A fall arresting device including a device housing, a shaft within the housing, a rotor assembly rotatably connected to the shaft that includes a drum and a disc having at least one region of a ferromagnetic material, an extendable lifeline connected to the drum, a magnetic sensor positioned stationary relative to the device housing and adjacent to the disc, and a that includes a hard-magnetic material. The magnet positioned stationary relative the device housing and the magnetic sensor, where the magnetic sensor is configured to detect a change in a magnetic field produced by the magnet when the disc rotates about the shaft, the change in the magnetic field induced by the at least one region of the ferromagnetic material being brought within close proximity to the magnet as the disc rotates.

A controller (1) for performing presence detection with a first sensor system (41,42) and a second sensor system (31-37) is configured to receive sensor signals from the first sensor system and/or the second sensor system. The second sensor system is of a different type than the first sensor system. The controller is further configured to determine which first one or more areas of the plurality of areas are in both the sensor range of the first sensor system and the sensor range of the second sensor system based on the sensor signals and control the second sensor system to perform, with respect to the first one or more areas, a second task other than a first task to be performed by the first sensor system. The first task comprises obtaining sensor data to be used for presence detection in the first one or more areas.
