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.

The invention involves a sensor (100) with a Bragg network fiber including a source (105) and detection system (101), operating at a wavelength of a given study, in addition to a Bragg (6) network fiber (1) linked to said source and said system, with said fiber being a microstructured optic fiber whose sheath (5) includes channels (3) adjacent to the heart (2) of the fiber (1), capable of receiving a product to be analyzed, characterized in that the number of channels (3) adjacent to the heart (2) is between 2 and 5, and that the size of the heart (2) of the fiber (1) is adapted so that an electromagnetic field of a wave guided by the fiber is not confined in the heart (2) of the fiber (1), and the electromagnetic field extends into the channels (3).
摘要:
The system produces movements in a home entertainment chair. It has a motor controller and a plurality of movement generator units for generating small amplitude and low frequency movements in the viewer's chair. The system is intended for home use and can be easily installed under each leg of a chair or of a sofa. The source of movement control signals can be derived from a video presentation soundtrack, and directional movement sensations can be created by inducing controlled movements in each leg of the viewer's chair.
摘要:
A motion simulator for transmitting motion with respect to a floor as a function of motion signals associated to a video output. The motion simulator comprises a seating portion for accommodating a viewer viewing the video output. Actuators each have a housing and an output shaft interrelated by a degree of freedom. Each of the actuators has a motor connected to the seating portion for displacing the housing with respect to the output shaft along the degree of freedom as a function of actuation from the actuators in relation to the motion signals. The housing of each of the actuators is secured to the seating portion. The output shaft of each of the actuators comprises a leg supporting the motion simulator on the floor, whereby the seating portion is movable as a function of actuation from the actuators.

Passenger seating arrangements are detailed. At least some arrangements permit each passenger to access an aisle of a vessel without contacting an adjacent passenger. Movable footwells may be utilized to floor-level access when retracted and function as steps when extended as a seat is converted to a bed. This structure authorizes decrease in seat pitch without decrease of bed length, permitting additional seating to be included in a cabin of a vessel without diminishment of passenger comfort.
摘要:
Described are passenger seats including a lower frame comprising a pair of supports, a seat pan adjustably coupled to the pair of supports via a coupling system, and a rear leg coupled to the lower frame, wherein the rear leg includes an extension component that is configured to adjust a height of the rear leg. The passenger seat may be adjusted into a bed position by compressing the rear leg, adjusting the seat pan into a forward position relative to the lower frame, and reclining the seat back until the seat back is substantially proximate the lower frame.
摘要:
The invention relates to a flotation element for vessels, consisting of concrete comprising closed-cell expanded foam beads, such as polypropylene beads, which are coated with a flexible binder, such as polyurethane, whereby the unfilled inter-bead volumes do not exceed approximately 20% of the volume of the floatation element. Preferably, one such floatation element comprises a concrete core as indicated above, a polyurethane coating around the core and a bonding film, such as polyurethane, which is disposed between the core and the coating. The invention is suitable for the construction of vessel floats.
