A device may receive frames of a video capturing an analog meter with a dial and a needle, may process the frames to identify a center, a radius, and a perimeter of the dial, and may determine calibrated values for the dial. The device may apply a model to one of the frames to create a base mask, may apply thresholding for a dynamic HSV bounding value, to the base mask and the frames, to create masked frames, and may identify contours for the masked frames. The device may identify a quantity of points for each of the contours, may estimate angles of the needle of the analog meter based on the quantity of points, and may average the estimated angles to determine an averaged needle angle. The device may determine a needle direction based on the averaged needle angle and may calculate a meter reading.

A vitals monitoring handcuff apparatus comprising a housing structure that is adapted to be coupled with a set of handcuffs and to contain a plurality of modules and units; a first module that is located within the housing structure and adapted to measure a wearer's heartrate via a sensor; a second module that is located within the housing structure and is adapted to measure the wearer's respiration rate via a sensor; a controller unit that is located within the housing structure, is configured to relay instructional programs to the modules and units which causes the modules and units to operate, and the controller unit receives data from the modules and inputs that data into associated algorithms that produce corresponding output signals; a communication unit that is located within the housing structure and receives the output signals from the controller unit and is adapted to relay the output signals to a user; and a rechargeable power unit located within the housing structure that is accessed by a port on an exterior of the housing structure, provides power to the vitals monitoring handcuff apparatus's other modules and units, and having a receiver which connects with an exterior power source via the port.

A home occupancy status and information system may be used to track information about human and animal occupants within a structure, and provide information to first responders in the event of an emergency. A rescue beacon may be positioned near an entrance to a home, and when an audible alarm or alarm signal is detected by the beacon it will provide visual alerts and/or audible alerts to attract the attention of a first responder, and will provide information on occupants in the home, such as a number of pets, a number of humans, and other information. A rescue device may also be carried by each pet or other occupant in the house, which may be activated by a wireless signal from a rescue beacon, or by a detected alarm audio/signal. When activated, the rescue device will provide audible and/or visual alerts to aid first responders in locating the occupant.

A graphical audio station of a nurse call system is operable to permit a user to perform one or more of the following functions: establish a two-way voice communication link with another computer device in another patient and/or with a another computer device located in another staff work area and/or with a wireless communication device carried by caregiver and/or with a telephone of the healthcare facility; broadcast a voice page to a group of other selected computer devices; compose and send a text message to a portable device that is carried by a caregiver and that has wireless communication capability; browse web pages and/or view multimedia content, such as videos, hosted on servers of the healthcare facility and/or that are accessible via the Internet; view and/or acknowledge and/or answer and/or cancel alerts or nurse calls originating in a plurality of patient rooms.

A medical fluid delivery system and apparatus for remote machine updating and control are disclosed. An example medical fluid delivery apparatus includes a processor and a dialysis fluid circuit including at least one dialysis fluid pump. The processor is configured to receive a disinfection input to begin a disinfection procedure and cause the at least one dialysis fluid pump to perform a disinfection procedure on the dialysis fluid circuit using a disinfection fluid. The processor is also configured to, after the disinfection procedure is complete, start a disinfection timer. When a dialysis input is received before the disinfection timer reaches zero, the processor enables a dialysis treatment to be performed. When the disinfection timer reaches zero before the dialysis input is received, the processor prevents the dialysis treatment from being performed until the disinfection procedure is performed again.

A cloud-based, geospatially-enabled data recording, notification, and rendering system.

A heart lung machine (HLM) includes: a pump actuator; an actuator control unit (ACU) operably connected to the pump actuator; a processing unit configured to receive a set of parameter data from the actuator; a display device configured to present a subset of the set of parameter data; and an input control device operably connected to the pump actuator. The input control device includes a rotatable knob. The ACU may be configured to: determine that the pump actuator has been stopped in response to a pump-stop trigger event; determine that the rotatable knob has been rotated to a first position; and in response to determining that the rotatable knob has been rotated to the first position, starting the pump actuator.
