Abstract: This invention generally provides two tactile stimulation modules, or “tappers”. One tapper is held by a person in each of his hands. Alternatively, a tapper is secured to each wrist or to other parts of the body on opposite sides. Each tapper is powered by a rechargeable battery, and contains both a tactile stimulation transducer, such as an electric motor having either a balanced or unbalanced mass on its output shaft, and a transceiver that communicates with a host or master. Each tapper includes at least one control button and a status indicator. Each tapper contains a micro-controller that performs tasks such as communication, motor activation, user monitoring and control, battery monitoring, low-power sleep, and algorithm execution. At least one tapper can contain at least one optional sensor, which measures a physiological function. Measurements can be used to modify performance of the tactile stimulation transducers.

Abstract: There is described a drainage system comprising: an inlet pipe; and an energy dissipater comprising a dissipation chamber. The dissipation chamber has a dissipater inlet fluidically connected to the inlet pipe and a dissipater outlet arranged to discharge fluid from the dissipation chamber. The dissipater inlet extends between a first end and a second end. A wall of the inlet pipe extends tangentially from the dissipation chamber so as to define the first end and such that, in use, fluid is discharged into the dissipation chamber in a tangential direction, thereby inducing a circulating flow within the dissipation chamber about an axis of the dissipation chamber. The width of the dissipater inlet in a direction parallel to the axis decreases from the first end to the second end.

Abstract: A turbomachine vane includes an electroacoustic source including two membranes fixed on a support arranged such that the membranes and the support delimit a first cavity. The membranes are arranged on two opposite sides of the first cavity between the two aerodynamic surfaces of the vane. A first of the aerodynamic surfaces includes a first region arranged facing a first of the membranes for the passage of acoustic waves. The membranes and membrane vibration device are configured such that the membranes vibrate in phase opposition and along a same emission direction by applying forces to the support such that the resultant force is approximately zero. The mechanical energy lost in the form of vane deformations due to membrane vibrations can thus be minimized.

Abstract: A three-dimensional imaging system relies on effective native image resolution reduction in order to provide an array of pixel clusters, or voxels, with each pixel of the voxel representing a pixel of the image from a unique viewing angle. A 16-megapixel screen having 16-pixel voxels results in a screen having an image capacity downgraded to a 1-megapixel screen capable of showing sixteen different viewing angles. The system can be set up as a rear-projection screen or as a reflective screen illuminated by a front projector. The invention is best implemented with projectors and screens that represent all colors at a single physical location, such as a 3-panel LCD color-combinant projector or a DLP projector, either single or triple chip type. When the RGB sub-pixels are non-coincident, the viewers will see color artifacts that detract from the viewing experience.
