In a method for monitoring and / or determining the condition of a force-measuring device with at least one housing that has an interior space and with at least one force-measuring cell installed in the interior space of the at least one housing, at least one parameter of the atmospheric climate of the interior space is measured with at least one sensor that is arranged in the interior space of the housing or with at least one sensor that is arranged at the housing, wherein said parameter is of a kind that has an influence on the operating lifetime of the force-measuring cell; and a sensor signal corresponding to the measured parameter of the atmospheric climate of the interior space is transmitted to a computing unit and / or to a data output device.

Marking devices for dispensing a marking substance on the ground and marking methods are provided. The marking devices and marking methods use one or more detection mechanisms to detect one or more characteristics of the marking substance. In some embodiments, the detection mechanism may be, but is not limited to, an optical sensor, an olfactory sensor, a weight sensor, a switch device, and any combination thereof. The one or more detection mechanisms may provide, for example, the capability to: (1) determine the type of marking substance that is installed in the marking device; (2) determine in advance of or during a marking operation the amount of marking substance within the marking dispenser; and (3) determine when the marking dispenser is becoming empty.

According to one aspect of the invention, a force measurement system includes a force measurement assembly, a motion base configured to displace the force measurement assembly, and an inertial compensation system configured to determine the inertial forces and / or moments resulting from the displacement of the force measurement assembly by the motion base. According to another aspect of the invention, a method for accurately determining the forces and / or moments applied to a surface of a force measurement device by a subject disposed thereon is disclosed, which includes the step of determining, by using an inertial compensation system, the inertial forces and / or moments resulting from the displacement of a force measurement assembly by a motion base. According to still another aspect of the invention, a force and / or motion measurement system having inertial compensation includes a motion acquisition system having a plurality of motion sensing devices configured to capture a subject's movement.

An apparatus for measuring the weight of items on a conveyor includes a scale that generates a first signal corresponding to the weight of the items. A movable platform transports the items to the scale and generates a second signal corresponding to position of the items in relation to the scale. A dimensioner examines the items and generates a third signal representative of whether the items are singulated or nonsingulated. A processor receives the second and third signals and determines whether to associate the first signal with information stored in memory about a particular item based upon whether the particular item is singulated or nonsingulated.

A surgical sponge detection system includes a plurality of surgical sponges (2) having radio frequency identification tags (1) securely attached thereto and a non-optical hand-held reader (40) for detecting the sponges by detecting the tags (1). Also disclosed is a device (30) for automatically counting, weighing, and calculating blood loss contained within, soiled surgical sponges (2) which includes a cabinet with an opening (3) at the top through which sponges (2) are deposited, a reader (6) which scans each sponge (2) entered and determines sponge type from a tag (1) affixed to each sponge (2), and a disposable bag (8) into which the sponges (2) are deposited. The disposable bag (8) is removably mounted to a weighing scale (10); there is also a rear door (9) from which the disposable bag (8) can be easily removed, a rechargeable battery (11), a shelf (12) for unused disposable bag storage, a control unit (4) which processes data received from reader (6) and scale (10) and instantaneously calculates total weight of liquid contained within sponges entered, a display panel (5) continuously displays the number and type of sponges entered during a given procedure as well as the total weight of liquids retained in those sponges. There is a means for automatically determining the weight of the sponges when dry which includes a non-optical scanner means (6) which can read an indicating means (1) on the sponges (2) even when the indicating means (1) is covered with blood or other body fluids.

An apparatus comprising of a segmented instrument tray, precision scale, image processing system, photoelectric sensors and a Personal Computer (PC) is disclosed. Said apparatus provides an automated and accurate tracking of surgical instruments used during surgical operating procedure by counting and identifying a specific quantity and instrument type, which are removed from a sterilized instrument tray to be used during the procedure and subsequently returned to the tray upon procedure completion, thus preventing an accidental leaving of an instrument inside of a patient and significantly reducing time spent by the operation staff for the instrument accounting.

A sensing and analysis system, method, and network that make use of a very portable and compact sensor unit and a physically separate electronic unit that serves to power and control the sensor unit, process and optionally display the output of the sensor unit, and transmit the sensor output to other locations, such as over a network. The sensor unit includes a housing, a sensing element within the housing and responsive to an input, and electronic circuitry within the housing and in communication with the sensing element to produce an electrical output based on an output signal generated by the sensing element. A communication providing device delivers instructions generated by the electronic unit to the sensor unit and delivers the electrical output from the sensor unit to the electronic unit.

A patient hydration system with a patient urine output measurement device, a hydration fluid administration subsystem, and a controller, responsive to the patient urine output measurement device. The controller is configured to control the hydration fluid administration subsystem to administer hydration fluid to the patient to prevent dehydration of the patient. A hydration sensor is also included to detect at least one patient parameter indicative of the patient's hydration state.
