Abstract:
The present document describes a system and method for controlling the movements of a motion platform in real-time based on the movements of a remote subject. For example, the user of the motion platform may experience movements/vibrations that correspond to the movements of a motorcycle in a live racing event. The system comprises a motion capture system which determines the movement of the remote subject. The output of the motion capture system is used by an encoder to generate motion signals which cause the motion platform to produce movements which correspond to the movements of the remote subject. The motion signals are sent to the motion platform over a communication link. In an embodiment, the remote subject is provided with one or more motion sensors which communicate with the motion capture system over another communication link.
Abstract:
In a building equipped with a plurality of motion-enabled chairs such as a movie theatre, the vibration of the motion-enabled chairs adds up and may damage the foundation of the building especially at the resonance frequency. The present application describes a system and method for controlling the resulting vibration by introducing an alteration such as a delay or an inversion in the motion signals sent to the motion-enabled chairs. This delay causes the vibration of some motion-enabled chairs to be de-phased from the vibration of the other motion- enabled chairs. Whereby, the intensity (magnitude) of the resulting vibration is reduced. Control of the motion-enabled chairs may be done centrally through a central controller, or locally at selected motion-enabled chairs.
Abstract:
A process of producing granules of a reactive metal. The process comprises providing a source of molten reactive metal (41), forming discrete droplets (53) of the molten metal, contacting the droplets while still substantially molten with a fluidized bed of particles (12) maintained at a temperature substantially below the solidus temperature of the metal and freezing the droplets as discrete granules of the reactive metal in the fluidized bed. The invention also provides apparatus for carrying out the method and product produced by the method, including a magnesium-containing additive for aluminium alloying. The use of a fluidized bed for cooling and freezing the droplets avoids problems encountered in prior methods and also makes it possible to provide coatings of various kinds on the surfaces of the granules, if desired.
Abstract:
The present document describes a vibro-kinetic seating kit for providing seating to a user at a seating location in a multi-seating environment comprising other seating locations and for rendering a vibro-kinetic effect to the user. The vibro-kinetic seating kit comprises an electronic display and a vibro-kinetic platform which comprises a seat portion associated with the seating location and for providing the seating to the user; and an actuation system mechanically connected to the seat portion for rendering the vibro-kinetic effect to the user. The electronic display associated to the vibro-kinetic platform is for receiving display data and for electronically showing visual information indicative of the display data which comprises an identification tag for the seating location relative to the other seating locations in the multi-seating environment.
Abstract:
The present document describes a link member for providing an interface between an actuator and a seat base. The link member has a translational degree of freedom and at least two rotational degrees of freedom. The link member comprises: a joint member having a spherical surface, the joint member for attachment to one of the actuator and the seat base; a housing for attachment to the other one of the actuator and the seat base; and a slider mounted on the spherical surface and within the housing. The slider is free to move in a direction of a translational plane within the housing thereby providing the translational degree of freedom. Furthermore, the slider is free to slide on the spherical surface and to pivot about a first axis and a second axis thereby providing the at least two rotational degrees of freedom
Abstract:
A diagnostic tool for detection of dental pathology is provided that functions as a self-contained, handheld unit. The tool includes a light probe and a housing within which are located an optical source, an optical detector, an analysis processor and a power source. The components within the housing are integrated on a support which is removable from the housing. The housing is in multiple pieces which may be connected together during operation, and disconnected to allow removal of the support. This allows for sterilization of the housing and light probe without the electrical components of the device.
Abstract:
A portable vital sign monitor is provided which has a palm vital sign monitor unit carried by the patient, the unit comprising an optical probe positioned in the palm of the patient which measures at least one vital sign including Sp0 2 and pulse rate but not exclusively and only those vital signs. The detected vital signs are stored in memory and transmitted by wireless interconnection to a communication base unit, which transmits the vital sign by a phone line, LAN, Internet, serial interface or the like to a data processing device/centre.
