摘要:
Pressure in a pad (17, 18) for application to the human body is controlled using a piston/diaphragm and cylinder device (19). The piston or diaphragm both acts to apply a force to increase/decrease pressure in the pad and experiences the pressure existing in the pad, thus eliminating the need for a pressure transducer in the pad. In preferred embodiments a deadload-balancing pressure is applied to the rear of the piston or diaphragm. A reservoir (41) whose pressure can be altered may be used to produce different values of deadload-balancing pressure. Preferably the piston/diaphragm is electromagnetically actuated, in particular using devices of the type described in WO93/01646. The pad or pads (17, 18) whose pressure is controlled may be provided in a variety of devices, such as a motion simulation seat, a bed or mattress, a massage cuff or sleeve, or a vehicle seat.

An aircraft simulator including means for determining the g-force acting on the simulated aircraft in response to the operator's controls and means for applying to a helmet (3) worn by the operator a vertical force dependent on said g-force. The means for applying a vertical force to the helmet may comprise a pneumatic piston/cylinder arrangement (14, 15, 16) responsive both to a g-demand signal determined by the position of the controls and to means (22) for monitoring the force exerted on the helmet. The piston (15) conveniently acts across adjacent sides (8, 9) of a parallelogram linkage (6, 7, 8, 9) interconnecting a mounting (4, 5) for the helmet and a fixed support (12), enabling horizontal, vertical and rotational movements of the helmet to be made and monitored.

A virtual-reality navigation controller includes a base and a seating portion. The seating portion includes a seat for supporting a weight of a user seated thereon, and a back-rest coupled to the seat to move integrally with the seat and to support the user's back. The virtual-reality navigation controller further includes a displacement connector between the seating portion and the base to reciprocate the seating portion upwards and downwards, and a motion-detection controller to measure upwards and downwards displacement of the seating portion. The displacement connector is configured to move the seating portion upwards along with the user to support the user when the user ascends from the seat during virtual-reality activities. The displacement connector is further configured to move the seating portion downwards at a slower maximum speed than the upwards movement, when the user's body rests back on the seat.
摘要:
Simulateur de vol comprenant des moyens permettant d'évaluer la force d'accélération due à la gravité agissant sur l'avion simulé en réponse aux commandes de l'opérateur, et des moyens permettant d'appliquer une force verticale en fonction dudit facteur de charge au casque (3) porté par l'opérateur. Les moyens d'application de la charge verticale au casque peuvent comprendre un agencement cylindre piston pneumatique (14, 15, 16) sensible à la fois à un signal de demande de charge déterminé par la position des manettes de commande et à des moyens (22) de surveillance de la charge exercée sur le casque. Le piston (15) agit de manière appropriée par-dessus des côtés contigus (8, 9) d'un élément de raccordement en parallélogramme (6, 7, 8, 9) reliant une monture (4, 5) pour le casque et un support fixe (12), ce qui permet au casque d'effectuer des mouvements horizontaux, verticaux et rotatifs, ces mouvements pouvant être surveillés.

摘要:
A virtual-reality navigation controller includes a base and a seating portion. The seating portion includes a seat for supporting a weight of a user seated thereon and a back-rest coupled to the seat to move integrally with the seat and to support the user's back. The virtual-reality navigation controller further includes a vertical support to support the seating portion on the base, and a rotatable connector between the seating portion and the vertical support to tilt the seating portion about a rotational center of the rotatable connector when the user is seated on the seat. A radius of an arc formed by the tilting about the rotational center ranges from 300 mm to 800 mm. The virtual-reality navigation controller further includes a motion-detection controller to measure pitch corresponding to the tilt of the seating portion.
摘要:
A motion simulator in the form of a seat (11) comprising a seat support frame (12) including a seat back (13), in which a seat pan (19) is movably mounted with respect to the seat support frame (12) via motion actuators (20, 21, 22) which impart to the seat pan (19) motion with respect to the seat support frame (12) with at least three degrees of freedom including sway, and control means (34) for determining the motion of the actuators (20, 21, 22) to move the seat pan (19). Many cues involve moving the seat pan in the opposite sense from the simulated direction of movement.
