In one example, this disclosure describes a method including receiving, at a central controller of an air mattress system, a plurality of air pressure value, determining a plurality of average values using the plurality of the received air pressure values, calculating a difference value between a first one of the plurality of average values and a second one of the plurality of average values, comparing the difference value to a threshold value, determining, based on the comparison, whether a user of the air mattress system moved.

An adjusting method and an adjusting system are provided. The adjusting method for human body support device includes the following steps: extracting a pressure distribution information when a user is lying on a human body support device; analyzing a posture of the user based on the pressure distribution information; analyzing a human musculoskeletal distribution information of the skeleton-muscle of the user and a plurality of coordinate values corresponding to the skeleton-muscle of the user based on the pressure distribution information; obtaining a plurality of high-risk regions corresponding to the plurality of pressure regions based on the human musculoskeletal distribution information, a plurality of coordinate values corresponding to the skeleton-muscle of the user, and the posture of the user; and adjusting a pressure value configuration of an airbag module of the human body support device based on the plurality of high-risk regions.

A massage chair includes a back massage system and a thigh massage system with a roller mechanism configured to move a roller in a three dimensional orbital motion. The roller mechanism is driven by a single motor that can change the direction in operation. Also included is a roller motion drive element within the roller mechanism. A shaft is configured to pass through the roller motion drive element in an offset non-perpendicular angle relative to the end face thereby forming an angle between the shaft and the end face that is less than 85 degrees. The offset causes the orbital motion of the roller when rotated. The electronics of the massage chair facilitate facial recognition and a medical assessment device to detect bodily characteristics. The backrest of the massage chair can elongate to stretch the user. A plurality of airbags are also available for the twisting of the user.

An assembly is disclosed. The assembly has a sleep pattern module, comprising computer-executable code stored in non-volatile memory, a processor, a sensor array, and a device array. The sleep pattern module, the processor, the sensor array, and the device array are configured to sense data of a sleep subject using the sensor array, process the sensed data, issue an alert to a guardian of the sleep subject based on the processed data, control the device array based on the processed data, and provide sleep pattern modification recommendations to the guardian of the sleep subject based on the processed data.

A vehicle seat is provided with a side support device configured to assist vehicle exit behavior of an occupant while stably securing a holding property for the sitting occupant. The vehicle seat includes a side support device configured to support a cushion side portion of a seat cushion to be switchable between a seating available position and a vehicle exit assist position, a lock device configured to lock the cushion side portion in the seating available position, and a lock release device configured to release a lock state of the lock device. The lock release device includes a first lever configured to detect sitting of the occupant on a cushion center portion and a second lever configured to detect sitting of the occupant on the cushion side portion. The lock state is released when the detection by the second lever occurs while the detection by the first lever continues.

A furniture system includes an office productivity structure (OPS). The furniture system also includes a sensor coupled to the OPS, the sensor operable to detect a parameter of the OPS and generate an output signal indicative of the parameter; and a processor coupled to the sensor. The processor is operable to receive the output signal generated by the sensor, determine, based on the output signal, an operation condition of the OPS, when the operation condition is determined to be within a satisfactory range, determine an estimated time before servicing is needed, and when the operation condition is determined to be outside a satisfactory range, send a service alert.

An office seat is disclosed. The office seat includes a seat body; an adjustment mechanism for adjusting a sitting posture of a user by adjusting a state of the seat body, and the adjustment mechanism being provided on the seat body; an image capture device for detecting the contour of the user's body; a controller, the controller being connected to the adjustment mechanism and the image capture device, respectively, and controlling the adjustment mechanism to adjust the seat body according to the detection result of the image capture device. In certain embodiments the office seat may be able to adjust the user's sitting posture, protect the user's physical health, be comfortable in use.

A computer cockpit including a cockpit body, a driving module, a sensing module and a controlling module. The cockpit body includes a seat, a backrest and a display interface all movably disposed on the cockpit body. The display interface and the backrest are respectively located at two opposite sides of the seat. The driving module and the sensing module are disposed to the cockpit body, and the sensing module is configured to provide sensing data. The sensing data includes a seat pressure sensing value and a backrest pressure sensing value. The controlling module is electrically connected to the driving module and the sensing module, and configured to send an adjusting command according to the sensing data. The driving module is configured to receive the adjusting command to synchronously rotate the seat, the backrest and the display interface to a working angle and reduce a difference between the backrest pressure sensing value and the seat pressure sensing value.

A vehicle seating system having a seat part includes a non-foam base material covered with a trim material. The non-foam base material may include a plurality of different firmness zones based at least in part on at least one of a seated-occupant pressure map and a structural arrangement disposed adjacent to the seat part. The seat part may be, for example, a seat cushion, a seat back, or a seat bolster.

The invention relates to the field of wheelchairs and has been designed for the measurement of parameters for the adjustment of a seated position of the user. It relates to a device for the simulation of a seated position in a wheelchair, which includes a seat backrest (1) adjustable horizontally, vertically and during its reclination, two side seat pans (27) with armrests (3) with adjustable distance, a foldable seat pan (2) with adjustable reclination, two wheels (4) with adjustable horizontal and vertical position, and a footrest (5) with adjustable vertical position and its reclination, at least one electric motor or an electric piston (15) for the adjustment of the position of the adjustable components, an electronic circuit with special software for the control of the motors and the display of the measurements, as well as a virtual reality software. With this device, it is possible to measure the adjustment parameters for the seated position of a wheelchair user automatically and digitally by means of a software which is installed in the simulation device.
