Abstract: A patient support for supporting a patient includes an inflatable mattress having at least one bladder forming at least part of a patient support surface, a pneumatic system for inflating the inflatable mattress, and a control system. The control system including at least one sensor, which includes an emitter and a receiver, with the emitter directing light into the bladder. The receiver receives a reflection from the light directed into the bladder, and the control system detects the immersion of a patient into the mattress based on the reflection received by the receiver.

Abstract: A patient support for supporting a patient includes an inflatable mattress defining a support surface and a pneumatic system for inflating the inflatable mattress. The pneumatic system includes a pressurized reservoir for holding pressurized air and selectively releases pressurized air from the reservoir to the mattress.

Abstract: A patient support for a patient includes a mattress with at least one air operated component and a cushioning layer forming a patient support surface. The mattress has a recessed portion beneath the patient support surface at the foot end of the mattress with an enclosure housed in the recess. The enclosure houses therein at least one pump for directing air to the air operated component and a controller for operating the pump. The enclosure has a central section and two side sections, with each of the sections having an upper side. The side sections are located on opposed sides of the central section and at opposed sides of the mattress at the foot end. The upper side of the central section is recessed below the upper sides of the side sections wherein the depth of the cushioning layer at the foot end between the side sections is maintained generally constant at least along the central portion of the mattress extending from the head end to the foot end.

Abstract: A patient support apparatus, such as a bed, stretcher, or the like, includes a support deck having a plurality of pivotable sections adapted to support a patient thereon. A head section of the support deck generally supports a patient's torso and is movable between a generally horizontal orientation and a raised orientation. A CPR drop assembly allows the head section to be pivoted relatively quickly to the horizontal orientation in order to allow CPR (cardiopulmonary resuscitation) to be administered to the patient. The drop assembly may include a foot pedal having both a mechanical and electrical link to an actuator. The drop assembly may also be configured to operate in different manners depending upon the angular orientation of the head section at the time the drop assembly is initially activated.

Abstract: The present invention provides a control system for a bathing unit that comprises a heating module, a temperature sensing entity and a heating module controller. The heating module includes a body that defines a passage through which water can flow, that has an inner surface and an outer surface. The heating module further includes a heating device that is operative for heating the water that flows through the body. The temperature sensing entity is mounted to the outer surface of the body such that the temperature sensing entity is in thermally conductive communication with water flowing through the body. The heating module controller is operative for obtaining temperature information associated with the temperature sensing entity for detecting at least in part on the basis of the temperature information the sufficiency of water flow through the body.

Abstract: A temperature control system for a bathing unit that includes a water holding receptacle and a heating module. The temperature control system comprises a plurality of actuators associated to the heating module and a temperature regulation device in communication with the actuators. The plurality of actuators are adapted for acquiring a first set of actuation patterns for causing the heating module to acquire a non-heating state and a second set of actuation patterns for causing the heating module to acquire a heating state. The temperature regulation device is operative for controlling the plurality of actuators to cause the heating module to acquire either one of the heating state or the non-heating state and for selecting a configuration from the first set of actuation patterns for causing the heating module to acquire the non-heating state. Alternatively, the temperature control system includes a solid state device associated with the heating module.

Abstract: A system for monitoring performance of one or more batteries in a battery plant facility. A set of sensors for each battery are used to measure a plurality of battery operation parameters comprising the battery current, battery voltage, and internal battery temperature of each said battery. A processor generates, for each battery, a plurality of battery status parameters comprising a true age parameter and a float capacity parameter. During a float period, the true age parameter is updated based on elapsed time corrected for battery temperature history and the float capacity is updated based on the most recent true age parameter. During a discharge period, the float capacity parameter is updated based on the evolution of plant voltage during the discharge. After the discharge period, at the beginning of a subsequent float period, the true age parameter is updated based on the float capacity parameter determined during the immediately previous discharge period.
