Abstract: An interchangeable stirrup system with an orthotic stirrup interface between a horse and a rider. Aspects include an improved stirrup, an orthotic riding boot, and an indexed interface between the stirrup and orthotic riding boot. Embodiments provide for a positive indexed engagement between the foot of a rider and the stirrups. The positive indexed engagement provides greater stability and control of the rider with the horse, improves safety of the rider and horse. An orthotic profile to the stirrup reduces pain and discomfort in the rider's feet.

Abstract: A ball game apparatus in which movements of a coded ball are detected by detector units and an automatic indication of a player’s score is given, where data relating to the ball are stored in a database connected to the detector units, the data including the code of a ball and a code relating to a player to whom the ball has been allocated, the ball being configured to temporarily store, and to intermittently transfer to the detector units and thence to the database, data relating to the ball’s movements. A rechargeable battery is contained within the ball, and is arranged to be charged by a battery charging system. Features of the game may be controlled by means of a player’s mobile telephone.

Abstract: A ball game apparatus in which movements of a coded ball (20) are detected by detector units (100, 206) and an automatic indication of a player's score is given, where data relating to the ball (20) are stored in a database connected to the detector units (100, 206), the data including the code of a ball (20) and a code relating to a player to whom the ball (20) has been allocated, the ball (20) being configured to temporarily store, and to intermittently transfer to the detector units (100, 206) and thence to the database, data relating to the ball's movements. A rechargeable battery (40) is contained within the ball (20), and is arranged to be charged by a battery charging system. Features of the game may be controlled by means of a player's mobile telephone.

Abstract: An orthotic stirrup interface between a horse and a rider is disclosed. Aspects of the invention include an improved stirrup, an orthotic riding boot, and an indexed interface between the stirrup and orthotic riding boot. Embodiments of the present invention provide for a positive indexed engagement between the foot of a rider and the stirrups. The positive indexed engagement provides greater stability and control of the rider with the horse, improves safety of the rider and horse. An orthotic profile to the stirrup reduces pain and discomfort in the rider's feet. Embodiments for each of a thoroughbred racing stirrup and a therapy riding stirrup and associated footwear are disclosed.

Abstract: A golf ball (10) including circuitry including a communications aerial (40) for communication with external components of the ball game apparatus, an internal holder member (20) in the form of a ring with components of the circuitry being located within the ring and at least one coil element (30) located externally of the ring.

Abstract: A ball game apparatus comprises a control device (14, 24, 52, 60) which defines a predetermined range of allowable movements of a ball (10, 20, 40, 70) over space and time, sensing means (12, 22, 42) for detecting the actual movements of a ball, comparison means for comparing an actual movement to the predetermined range of allowable movements, and indicating means (16, 34, 54, 62) for indicating the output of the said comparing. The sensing means (12, 22, 42) comprises a multi-axis accelerometer contained in the ball and having accelerometer, gyroscope and/or magnetometer functions. The ball may be activated by an internal magnetically-operated switch (17, 22, 47). The control device and indicating means can be incorporated in the ball itself or in a separate portable computing device.

Abstract: A filter element of a fresh air system of an internal combustion engine may include an annular filter body having a folded filter material and at least one end disc fastened to an axial end face of the filter body on the filter material. The filter material may have two end folds adjacent in the circumferential direction and be fastened to each other. The at least one end disc may have at least one alignment contour protruding at least one of radially and axially from a respective one of the at least one end disc.

Abstract: A golf ball struck by a player from a teeing area (22) to a second area (27) with golf holes (26), (30) passes beneath the lower edge (65) of a transparent screen (64) and then through photoelectric beam arrangements (66, 67). The holes (26, 30) incorporate ball sensors connected to a control device (60) which allocates scores. A selected hole may be illuminated and the control device rewards a successful putt into the selected hole with a higher score.
