A motion toy includes a body member and a head member mounted on the body member. A head drive system is operable to rotate the head member simultaneously up-and-down and side-to-side relative to the body member.

Inertial trackers have been successfully applied to a wide range of head mounted display (HMD) applications including virtual environment training, VR gaming and even fixed-base vehicle simulation, in which they have gained widespread acceptance due to their superior resolution and low latency. Until now, inertial trackers have not been used in applications which require tracking motion relative to a moving platform, such as motion-base simulators, virtual environment trainers deployed on board ...

A motion estimator capable of performing fast motion estimation during compression of a moving picture is provided. The motion estimator includes a first memory including a previous search area memory having a plurality of memory areas for storing previous search area data by lines and a current process area memory for storing current process area data by lines; a previous search area data provider; a first switching part for selecting the previous search area data; a second switching part for s...

A motion waterfowl decoy. The preferred embodiment has a pair of wings mounted to an axle such that the wings rotate with the axle. The wings' undersides are preferably lighter than their topsides. A pull cord is wound about the axle so that unwinding the cord will spin the axle and wings. As the wings rotate, their lighter underside is alternately displayed, creating a strobelike effect resembling wings flapping. A biasing device such as a length of rubber or latex tubing or a spring is attache...

The present motion detector unit effectively suppresses harmonic frequencies and is cost-effective to build. The motion detector unit includes a main casing which houses the main microwave circuit board (3). Enclosing the casing and the circuit board (3) is a cover. An antenna circuit board is attached to the bottom side of the main casing. The cover has partitioning walls at the bottom side of the cover which press against the main microwave circuit board (3) when the cover is enclosed over the...

Stabilization for devices such as hand-held camcorders segments a low-resolution frame into a region of reliable estimation, refines the motion vectors of that region hierarchically while at the same time updating the segmentation, finds a global motion vector for the region at high resolution, and uses the global motion vector to compensate for jitter.

A motion toy, which includes a toy body, and a power drive unit, the toy body having a front body shell and a rear body shell fastened together, two arms coupled to the body shells at two opposite lateral sides, a head pivotably mounted in the body shells at a top side by a pivot and coupled to the arms, two feet, and two legs coupled between the body shells and the feet, wherein two elongated links are coupled between the arms and a rocker, which is turned back and forth about a pivot between t...

In a method of estimating motion vectors, motion parameters (p1-p4) are determined (PC) for a given field (n-1) of a video signal; and motion vectors ( D(X, n) ) for a field (n) of said video signal are determined in dependence upon at least one predetermined motion vector ( D(x-X, y-Y, n), D(x+X, y-Y, n), D(x, y+2Y, n-1) ) and at least one additional motion vector (PV(X) derived (PG) from said motion parameters (p1-p4).

A motion stabilizer for yieldingly urging a relatively movable load member toward a normal or centered position relative to another load member includes a telescoping body that shortens (retracts) as the load members move toward one another and lengthens (extends) as the load members move apart. A reaction unit is mounted within an axially extending internal chamber defined within the body. The reaction unit has a normal length and a displaced length. The reaction unit may include a spring such ...

The present invention describes a catheter suitable for introduction into a tubular tissue for dissolving blockages in such tissue. The catheter is particularly useful for removing thrombi within blood vessels. In accordance with the preferred embodiments, a combination of vibrating motion and injection of a lysing agent is utilized to break up blockages in vessels. The vessels may be veins, arteries, ducts, intestines, or any lumen within the body that may become blocked from the material that ...
