A conventional monoplane mouse is constructed to move on a flat surface upon a single plane within which a contained sphere may rotate tangential with the single plane contacting the flat surface. Signal for XY cursor movement are derived from two or more counting sensors positioned at an equator of the rotatable sphere parallel with the single plane. The mouse invention defines two or more facets in the underside housing. The facet mouse can be tilted to one of the exclusive facets and moved on a flat surface to generate XY signals. The facet plane selected by tilt is identified by triggered pressure sensitive switches at each facet plane. The switches also function as undercarriage feet to define the virtual plane of contact to the flat surface. The facet planes in two and four facet embodiments are oriented with the orthogonally placed sphere counting sensors so that the interest of any two opposing facets is parallel with the plane of rotation of one of the counting wheels. A single sphere and counter apparatus can serve all facets, being placed at the intersect of all facets. To aid the hand in applying continuous downward pressure to the mouse onto a preferred facet, a hinged and elevatable palm hood is attached to the top of the mouse. The mouse enables a new user interface beyond the tradition ones of: 1.clicking keys by a finger and 2.whole arm movement of a mouse on an XY surface. By a tilting wrist motion, the user may instantly and continuously toggle 2,4, or more selection assigned to the facets provided.

In the pneumatic radial tire of the present invention, a total strength K0 of a belt layer 20 in a circumferential direction of the tire per unit of width at a tire equator surface position P0 is set greater than a total strength of the belt layer 20 in the circumferential direction of the tire per unit of width at a width position P2 corresponding to ⅔ of a maximum width of the belt layer having the tire equator surface CL as a center. In this way, it is possible to suppress the quantity consume of material in the belt layer 20, and to suppress the amount of expansion of tread rubber in a tread central region in the circumferential direction thereof when a standard internal pressure is charged and when the tire is rotated at high speed, thereby suppressing the growth of tire diameter. Since the expansion amount of the tread rubber in the circumferential direction is suppressed, the tension of the rubber is reduced. Therefore, it is possible to increase the resistance of the tread against the sticking of foreign matter, and even when foreign matter sticks in the tread, it is possible to suppress the growth of the crack.

Locating satellites (e.g., GPS) are culled into a sub-plurality based largely on dwell time within an inverted cone above a relevant site in communication with a wireless device. A first inverted cone having a first base angle is defined above a first site, a second inverted cone having a second base angle is defined above a second site. If the second site is farther from an equator of Earth than the first site, then the second inverted cone is made to have a base angle larger than a base angle of the first inverted cone. If the first site is farther from the equator of Earth than the second site, then the first inverted cone is made to have a base angle larger than a base angle of the second inverted cone. The span of the inverted cone over the site closest to the equator may be limited.

In accordance with the invention, a golf ball is marked with two equatorial O-rings adjacent an equator of the ball and equally spaced therefrom, which are in a golfer's full view of the top side of the ball when the ball is accurately aligned to its desired initial starting line and a golfer is properly positioned to putt. The polar regions of the ball are also imprinted with a pattern which is essentially invisible to the golfer when properly positioned to putt. When the ball is aligned to a particular starting direction, and properly struck precisely and squarely and rolls purely in that starting direction, the equatorial O-rings will roll without wobble, and the polar O-rings will remain essentially invisible to the golfer. But when side spin is imparted to the ball at impact, the equatorial O-rings (circumferential lines) will appear to wobble as the ball rolls, and the polar O-rings will become periodically visible and emphasize the appearance of wobble. The quantity of the polar region imprints which become visible and obvious, and which enhance the appearance of wobble as the ball is rolling, provides an indication of the extent to which side spin has been imparted to the ball by the putting stroke. This feedback to the golfer after every putt, as to the magnitude of the apparent wobble (i.e. amount of side spin) his or her stroke imparted at impact, allows the golfer to differentiate between good and poor putting strokes. Such learning will inevitably help the golfer improve his or her putting. A putter for use with the ball marked as described above includes a central region which simulates the appearance of a golf ball cover. Two lines are printed on this central region converging from the back of the putter toward the front surface with the lines adapted to be aligned with the equatorial O-rings on the ball. The regions of the upper surface of the putter contiguous to the central region may be printed or painted with a coating that simulates grass.
