A person support apparatus supports a person in a laying-down or a seated position. One or more body-mounted sensors detect changes in the position of the person relative to a reference. A control system receives output from the body-mounted sensor or sensors through a remote coupling. The control system uses patient position information obtained from the body-mounted sensors to determine whether the person has experienced a change-in-position and/or a change-in-activity event. Alternatively or in addition, the position of the person situated on a person support apparatus is detected using one or more sensors that are not body-mounted, but rather are coupled to the person support apparatus or to another component of a patient support system. The patient position information is used to estimate the patient's torso angle. The estimated torso angle is used to assess the patient's condition.

A communication system includes at least one first communicator, a second communicator, and a notifier. The at least one first communicator is installable in a boundary area between a first zone and a second zone. The second communicator is installable on a carried object to be carried by a person movable in the first zone. The second communicator communicates with the at least one first communicator. The notifier notifies the person carrying the carried object in response to the second communicator receiving a first signal from the at least one first communicator.

Illumination device includes light source for lighting up desktop, arm mechanism incorporates motor for moving position of light source, face camera detects position of eyes of user, desk cameras detects illuminance distribution on desk, image processing part calculates posture of user and distance between eyes of user and desk, based on face images obtained with face camera and desk images obtained with desk cameras, computation part calculates optimal light source position of light source wherein dispersion of illuminance distribution on desk is minimized, based on posture of user derived with image processing part and illuminance distribution obtained with desk camera, warning part that generates warning, in cases where distance is less than or equal to predetermined value, and control part operates arm mechanism such that light source moves to optimal light source position.

The present disclosure relates to a monitoring system configured to monitor the activities of individuals without having to keep the surrounding area under the surveillance of a camera thereby maintaining the privacy of the individual. In particular, the monitoring system includes a network of sensitive sensor units that are installed onto indoor flooring to record human footstep induced vibrations. The data collected from the sensors can then be processed to identify individual occupants, determine the number of occupants, estimate the location of footsteps, and track the trajectory of each occupant. The extracted trajectory information can be used to assess an occupant's personal activity and social interaction, which can then be used to analyze the individual's physical and psychological health.

An improved wearable locator has an ultra-low power RF transceiver, GPS receiver, cellular network RF transceiver, processor, programmable non-volatile memory, LCD display, accelerometer and rechargeable battery. To ensure that the locator is within a perimeter, it can cooperate with a subordinate unit that includes an ultra-low power RF transceiver, processor, power supply, DC charging output, rechargeable battery, visual, audible and tactile enunciators and pushbutton, and can be plugged into an outlet or be unplugged and be mobile. Other wireless units can be used to define a perimeter.

A warning circuit for use on ladders includes a first sensor responsive to the placement of a first of a user's feet thereon and a second sensor responsive to the placement of a second of the user's feet thereon. The second sensor is electrically connected in series to the first sensor, and a relay is electrically connected in series to one of the first and second sensors. A power source has a power output terminal electrically connected in series to the other of the sensors connected in series. A sound device is electrically connected to a load output of the relay and to the power source. The load output of the relay is energized only when the first sensor is activated prior to activation of the second sensor whereupon the load output then energizes the sound device.

A notification system is provided that provides notification of patient events such as movement and/or incontinence. The notification system provides for a plurality of different pressure sensor pads as well as an incontinence pad to be used in association with a single monitor.

The disclosed device, system, and method may comprise one or more devices for digital personal protective equipment. These devices may be network enabled wearables. A plurality of sensors, data transmission mechanisms, self-illuminating LEDs, and communication mechanisms may be embedded in a suspension or harness in various embodiments. A number of sensors may likewise be provided in a glove or earbud (ear plug). The device may measure various aspects of a wearer's movement and transmit that data over a data connection (such as a wifi or mobile connection) to a server. The server may house project and human resources data, worker and condition information, and materials and supplies data, according to various examples of embodiments. The system may further comprise one or more applications which may interpret the data provided.

In some implementations, a monitoring device associated with a lanyard device may detect that a portion of a strap of the lanyard device has extended from a strap core of the lanyard device. The monitoring device may generate a notification that the portion of the strap has extended from the strap core, wherein the lanyard device is configured to anchor the user to a support structure via the strap, and wherein a sensor within the monitoring device is configured to monitor a position of the strap relative to the strap core. The monitoring device may transmit, to a management device, the notification that the portion of the strap has extended from the strap core, wherein the notification includes an identifier associated with the lanyard device to alert the management device of a hazardous event involving the user.

A breathing system includes a facepiece and a regulator to deliver breathing gas to the facepiece. The regulator includes a sensor system including at least one sensor responsive to respiration of a user. The breathing system further includes a processor system in operative connection with the at least one sensor, a memory system in operative connection with the processor system and at least one algorithm stored in the memory system and executable by the processor system. The at least one algorithm is adapted, configured or programmed to determine at least one of a rate of respiration and a respiration volume from data from the at least one sensor. The algorithm is further adapted, configured or programmed to relate at least one of the rate of respiration and the respiration volume to a physiological state of the user.
