A force sensor provided with a base and a table with legs mounted on the base. The table is movable with respect to the base by a force applied to the table, and the sensor is further provided with a measuring instrument or instruments for measuring a deflection of one or more of the legs, which deflection represents said force applied to the table.

Embodiments of the present disclosure provide systems, apparatuses and methods for synchronous communication and control of LED lights and sensors in an LED light array containing two or more LED lights. Through the use of a master clock within a gateway and/or a master controller that is in communication with LED lights in an array that is in a facility, such as in a greenhouse, hot house, poultry egg production facility, a hospital, dairy production or other lighting facilities, the gateway and/or master controller is capable of synchronizing the emission of light or photons from an LED light array by generating a master signal that contains commands and time from a master clock within the signal that is transmitted to each of the LED lights within an array.

The invention describes a measurement method for the continuous non-invasive determination of blood pressure using two blood volume sensors, which are under two different applied pressures. The non-linear function, which is updated for each cardiac cycle, is used to model the relationship between blood pressure and relative blood volume change. The model depends on relative blood volume changes and applied external pressures to the sensors. The derived model needs one point blood pressure calibration. The blood volume sensor can be optical sensor, such as photoplethysmographic sensor, however, any transducer, which converts blood volume or relative blood volume to electrical signal, is applicable. As one possible application, the method can be used for the blood pressure determination at one finger. However, the method is not limited with the blood volume measurement sites (e.g. radial artery etc.).

Wearable ergonomics improvement systems and related methods are disclosed. An example ergonomics improvement system includes a membrane including a first frame having a plurality of first cutouts defining a first pattern. The system includes a sensor coupled to the membrane and includes a second frame having a plurality of second cutouts defining a second pattern. The first pattern is complementary to the second pattern.

A patient support apparatus, such as a bed, cot, stretcher, etc., for supporting a patient includes an exit detection system with multiple user-selectable modes of operation that each have different sensitivity levels for triggering an exit alert. The exit detection system also includes one or more non-user selectable modes of operation that are automatically implemented in response to a triggering action. For example, a transition mode may be automatically implemented when the user attempts to switch from a first user-selectable mode to a different user selectable mode, or a motion mode may be automatically implemented when movement of one or more components of the patient support apparatus occurs. In the transition mode, the exit detection system may use a least restrictive sensitivity level. In the motion mode, the exit detection system may inhibit exit alerts and/or change the criteria for issuing the exit alert.

One general aspect includes a bed having a mattress. The system also includes a sensor configured to: sense pressure of a sleeper on the mattress and transmit, to a controller, pressure data generated from the sensing of pressure of the sleeper on the mattress. The system also includes a controller may include a processor and a memory, the controller configured to receive the pressure data; identify, from the pressure data, one or more motion parameters; determine one or more cardiac measures of the sleeper from the motion parameters; determine, from the cardiac parameters, one or more neurologic measures of the sleeper; and determine, a disease state for the sleeper.

A person support apparatus, such as a bed, cot, stretcher, or the like, includes an exit detection system that utilizes an occupant motion parameter to determine whether to issue an alert or not. The motion parameter may be based on the weight and motion of the occupant. Successive positions of the occupant are determined in order to calculate a velocity of the occupant. In some embodiments, the kinetic energy of the occupant is used to determine if an alert should be issued. Objects positioned on the person support apparatus may also be detected and tracked. Auto-zeroing of a built-in scale, as well as automatic recognition of the removal, movement, and/or addition of objects is also provided.

An orthopedic system to monitor a parameter related to the muscular-skeletal system is disclosed. The orthopedic system includes electronic circuitry, at least one sensor, and a computer to receive measurement data in real-time. The orthopedic system comprises a first plurality of shims of a first type, a second plurality of a second type, a measurement module, and the computer. The measurement module houses the electronic circuitry and at least one sensor. The measurement module is adapted to be used with the first plurality of shims and the second plurality of shims. The measurement module has a medial surface that differs from a lateral surface by shape, size, or contour.

A system for automatically assessing orthostatic hypotension for a patient supported on a patient support apparatus. The system receives position data identifying a first position of a patient supported on a patient support apparatus, and after a delay, receives vital signs data of the patient. The system receives position data identifying a second position of the patient supported on the patient support apparatus, and after a delay, receives vital signs data of the patient. The system determines an orthostatic hypotension assessment based on a difference in the vital signs data between the first and second positions. Based on the orthostatic hypotension assessment, the system modifies one or more conditions on the patient support apparatus to mitigate a risk for patient fall.

The present disclosure provides devices, systems, and methods for the prognosis and management of diseases and conditions. In particular, the present disclosure provides devices, systems, and methods directed to a toilet apparatus for the automatic tracking of a subject's urination and bowel movements to enhance the diagnosis and treatment of various diseases and conditions.
