A method for monitoring an occupant of an occupant support comprises 1) establishing a lateral position history of the occupant, which history includes an assessment of how frequently the occupant's head undergoes a lateral transition on a head support, 2) establishing a vertical position history of the occupant which accounts for how frequently the weight of the occupant's head is applied to and removed from the head support, and 3) if the lateral position history indicates sustained repetitive lateral movement or the vertical history indicates other than sustained presence of the occupant's head on the head support, reporting that the occupant is in a state other than an acceptable state.

An automatic identification system for communicating identifying information by coupling signals through the human body is provided. The system includes a battery powered identification device that transmits an identifying signal via a modulated carrier. The identification device is coupled to the body of the user via a coupling plate. The signal from the identification device is received by a reading device that is also coupled to the body of the user via a coupling plate. The reading device may display and/or enunciates the identifying information to the user. The coupling technique, carrier frequency, and construction of the devices are such that the identification information is not inadvertently radiated or coupled to unintentional users or receivers.

The present invention includes a healthcare system for capturing and maintaining patient healthcare records and employing information in the records to proactively alert hospital workers to a condition that places patient health at risk.

A method and system for communicating estimated blood loss parameters of a patient to a user, the method comprising: receiving data representative of an image, of a fluid receiver; automatically detecting a region within the image associated with a volume of fluid received at the fluid receiver, the volume of fluid including a blood component; calculating an estimated amount of the blood component present in the volume of fluid based upon a color parameter represented in the region, and determining a bias error associated with the estimated amount of the blood component; updating an analysis of an aggregate amount of the blood component and an aggregate bias error associated with blood loss of the patient, based upon the estimated amount of the blood component and the bias error; and providing information from the analysis of the aggregate amount of the blood component and the aggregate bias error, to the user.

A bed-leaving sensor for detecting bed-leaving by a user on a bed, including: a sitting position detection member that detects a sitting position of the user based on a detection value of a pressure sensor arranged on the bed; a foot movement detection member for detecting foot movement of the user based on the detection value of the pressure sensor; and a bed-leaving behavior detection member that detects bed-leaving behavior of the user with the sitting position or the foot movement being detected within a preset bed-leaving expectation region as a condition.

The invention relates to a seating system (10) for a passenger aircraft, comprising at least one aircraft seat (12) having at least one sensor device (24) which is configured to detect a seat load on the aircraft seat (12) by a passenger (22) sitting thereon, an evaluation device (32) which is configured to determine a recommendation for a change in a sitting posture depending on the detected seat load and a display device (36) which is configured to display the recommendation.

Furthermore, the invention relates to a method, a program product and a sleeping system for a passenger aircraft.

A system includes one or more sensors to detect activities of a mobile object; and a processor coupled to the sensor and the wireless transceiver to classify sequences of motions into groups of similar postures each represented by a model and to apply the models to identify an activity of the object.

A fall detection system for detecting falls off a mobility vehicle includes a first sensor, a second sensor, and a processor disposed in the mobility vehicle or a mobile device. The first sensor is disposed on the mobility vehicle and generates a first sensor reading corresponding to movement of the mobility vehicle. The second sensor is disposed in the mobile device and generates a second sensor reading corresponding to movement of the mobile device. The processor is disposed in the mobility vehicle or the second vehicle, wherein the processor performs the following: a) retrieving the first sensor reading and the second sensor reading; b) determining a correlation between the first sensor reading and the second sensor reading and entering into a first mode if the correlation exceeds a minimum correlation threshold, otherwise repeating step a) after a first time period if the correlation is below the minimum correlation threshold; c) determining the correlation between the first sensor reading and the second sensor reading after a second time period, and entering into a second mode if the correlation is below the minimum correlation threshold; d) generating a fall detected signal if the correlation between the first sensor reading and the second sensor reading after a third time period correspond respectively to stationary movement of the mobility vehicle and the mobile device.

A patient support apparatus includes a load frame, a support frame, and a plurality of load cells supporting the load frame on the support frame such that a load supported by the load frame is supported by the load cells, each load cell configured to produce a signal indicative of a load weight bearing upon that load cell. The load cells are calibrated after installation.

A notification device is provided that includes a sensor pad, and an electronics module generates one or more notifications in response to signals received from the sensor pad. In a first embodiment, the sensor pad includes a pressure sensor for sensing pressure applied by a patient and generating a pressure signal, and conductive tracings for sensing moisture due to incontinence and generating a moisture detection signal when moisture is detected. In another embodiment, an absorbent sensor pad includes a sensor pad for sensing moisture and includes an absorbent chuck having a moisture-impermeable sheet with an absorbent material on an upper surface thereof, wherein the moisture-impermeable sheet has an aperture for receiving the sensor pad. The absorbent sensor pad may be provided in the form of a diaper.
