(canceled) ### Claim 13 An intelligent hospital bed comprising: a lower main frame, an upper frame provided with movable parts and articulated to the lower main frame, and a mattress provided with several foldable sections on which a patient rests, the mattress including a plurality of pressure sensors arranged along the mattress capable of measuring the initial force of the patient at a point at which the corresponding sensor is arranged, wherein the upper frame comprises: a lower assembly articulated to the lower main frame in at least two pivot points located at opposite ends of the lower main frame; and an upper assembly on which the mattress rests, the upper assembly being provided with a right side longitudinal support part, a left side longitudinal support part, and a central support part which are connected to each other, the left and right side longitudinal support parts being connected to and respectively articulated to left and right lateral ends of the central support part, such that each of the support parts is capable of being inclined, wherein the pressure sensors are interconnected and associated with a control unit which controls servo-motors used for moving the movable parts of the upper frame, such that when one or more of the sensors detects a movement of the patient in real time, the control unit creates a map of pressure images to be processed to actuate the specific servo-motors associated with the one or more of the sensors for moving at least one of the movable parts of the upper frame; and the lower assembly includes a raising/lowering mechanism articulated to the central support part of the upper assembly which allows movement of the central support part linearly up and down, and the raising/lowering mechanism being controlled by another of the servo-motors. ### Claim 14 (depends on 13) The hospital bed according to claim 13, wherein at least one of the longitudinal support parts is associated with one or more the servo-motors. ### Claim 15 (depends on 13) The hospital bed according to claim 13, wherein each of the support parts comprises a fixed portion to which there is pivotally articulated an inclinable portion which is linked to foldable sections of the mattress. ### Claim 16 (depends on 13) The hospital bed according to claim 13, further comprising: at least one first bar provided at a head end of the bed, which is capable can be actuated by one of servo-motors at the head end of the bed, the at least one first bar being articulated to the lower main frame and the lower assembly of the upper frame which follows an angular trajectory, at least one second bar provided at a foot end of the bed, which is capable of being actuated by one of the servo-motors at the foot end of the bed, the at least one second bar having one end articulated to the lower main frame and having a wheel on an opposite end thereof, the wheel being capable of sliding on a guide located in the lower assembly of the upper frame. ### Claim 17 (depends on 16) The hospital bed according to claim 16, wherein the servo-motor at the head end of the bed and the servo-motor at the foot end of the bed are operable independently from one another. ### Claim 18 (depends on 13) The hospital bed according to claim 13, wherein a fixed portion of each of the longitudinal support parts includes a structure defined by two stringers attached by transverse crosspieces, the end crosspieces including flanges provided with through holes through which pins acting as a rotating shaft are inserted. ### Claim 19 (depends on 13) The hospital bed according to claim 13, wherein the raising/lowering mechanism includes a rectangular framework provided with two sets of wheels, each of the sets being in opposite crosspieces of the rectangular framework, wherein the wheels are placed on guide rails located transversely with respect to a longitudinal axis of the lower assembly. ### Claim 20 (depends on 13) The hospital bed according to claim 13, wherein the lower main frame is provided with caster wheels. ### Claim 21 (depends on 13) The hospital bed according to claim 13, wherein the upper assembly is articulated to the lower main frame, and one or more of the servo-motors are provided which are capable of tilting the upper assembly in left and right directions with respect to a longitudinal axis of the lower main frame. ### Claim 22 (depends on 13) The hospital bed according to claim 13, wherein each of several portions of the mattress is provided with at least one of the sensors. ### Claim 23 (depends on 13) The hospital bed according to claim 13, wherein each of the lateral ends of the central support part articulated respectively to the right and left side support parts is provided with one of the servo-motors, such that each of the right and left side support parts is able to adopt a different inclination with respect to the central support part. ### Claim 24 (depends on 15) The hospital bed according to claim 15, wherein each of the lateral ends of the central support part articulated respectively to the right and left side support parts is provided with one of the servo-motors, such that each of the right and left side support parts is able to adopt a different inclination with respect to the central support part. ### Claim 25 (depends on 13) A method for operating the hospital bed according to claim 13, comprising a plurality of pressure sensors arranged on a mattress and a frame provided with movable parts which can be moved in real time by actuating means, comprising the steps of: obtaining a map of pressure images from data obtained by each of the sensors which are treated by a control unit controlling the movable parts; segmenting pressure images; calculating discriminating statistical characteristics of each of segment of the images; obtaining a relative difference of each of the characteristics of a patient resting on the bed with respect to the map of pressure images for quantifying a pressure evolution of the patient; and automatically recognizing a pattern indicating an intention of the patient to move from the discriminating statistical characteristics, and causing a movement of at least one of the movable parts of the frame in real time by action of the actuating means.
