A sensing apparatus may be provided capable of detecting a hit by a projectile, such as a BB pellet. The sensing apparatus may include a surface and accelerometer to detect the acceleration of the surface. A processor may determine whether a projectile hit has occurred. The sensing apparatus may be mounted onto a vehicle. The vehicle may be a robot capable of participating in a game. The robot game may occur within a facility.

Apparatus, systems, and methods for detecting projectile hits on a surface

A projector which includes a first exhaust fan discharging exhaust air from a light source lamp to exterior and a second exhaust fan discharging exhaust air from parts other than the light source lamp are arranged to be adjacent to each other. An end of the exhaust fan facing the other exhaust fan is moved to the inner side and the one exhaust fan is inclined to discharge air in an exhaust direction toward a direction along which air is discharged from the other exhaust fan. There is provided a cooling fan that blows air to an interior air blow outlet communicating with the interior of the light source lamp and exterior air blow outlets communicating with an outer surface to cool the light source lamp. The exterior air blow outlets are deviated from the center of the outer surface of the light source lamp.

In a projection image display apparatus, a noise removal filter portionis separated from a power source unit body. The separated noise removal filter portionis provided in the vicinity of a side wall of a housing on which a power source inlet is provided, and of the power source unit body, respectively. Specifically, the power source unit bodyis provided along a side wall of a front face of the horizontally-long housing of the projection image display apparatus and the noise removal filter portionis provided in a position opposed to the power source unit bodyin a side wall of the back face. As a result, even when a light source lamp has a higher output, the projection image display apparatus can achieve reduced noise by an improved cooling capability and reduced cost enabled by an efficient Electro Magnetic Compatibility (EMC) measure and the like.

Projection image display apparatus having a noise removal filter portion

A projector having optical components, a power source unit, and a light source unit. The projector is capable of lowering its internal temperature utilizing: a first, second, and third fan () provided near the optical components for introducing external air from outside the projector to cool the optical components; and a fourth, fifth, and sixth exhaust fan (). The fourth fan () blows the air that was taken in by the first, second, and third fan () and has cooled the optical components, onto the light source unit to further cool the light source unit. The fifth and sixth exhaust fans () discharge the air that has cooled the light source unit and power supply unit out of the projector.

Multistage cooling system for projector

A duct was configured such that an incident side and an outgoing side of each of liquid crystal panels, andare formed with discharge ports rand r, gand g, and band bto discharge the air from fanstothrough ductsto, and at the same time, a PBSfor aligning the polarizing direction of the light from a light source lamp is formed with a discharge port pto discharge the air from the fanthrough the duct, and an incident side discharge port band an outgoing side discharge port bof the liquid crystal panelcorresponding to the blue light are formed with the ducts so as to discharge the air from the fansandwhich are different from each other. As a result, even when an amount of light per unit area of high luminance is increased, the liquid crystal panels and the polarizing plates and the PBS can be effectively cooled by three sets of the fans.
