Abstract: A target system for projectiles comprises a support system, a primary target, and a secondary target. The support system defines a support portion. The primary target comprises a target portion defining a front side and a rear side, a hanging portion, and a clip arranged on a rear side of the target portion. The clip is adapted to engage the secondary target to secure a secondary target relative to the primary target. The hanging portion is adapted to engage the support portion of the support system to support the primary target at a desired location.

Abstract: A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

Abstract: A paddleball toy having a paddle, a bounceable play ball, and an elastic tethering means. The paddle has an impact surface and an elongate handle with a handle longitudinal axis. The paddle has a front side and a back side. The handle connects to the impact surface at a lower end of the impact surface. The impact surface has a direction-switch slot extending from a slot bottom at an interior point of the impact surface to an exterior edge of the impact surface. The elastic tethering means tethers the play ball at a first end of the tethering means to a tether spot on the impact surface adjacent the slot bottom of the direction-switch slot so as to permit the tethering means to pass through the direction-switch slot as the play ball passes the impact surface from front side to back side, or back side to front side.

Abstract: A bat and ball game apparatus comprises:

Abstract: A batting training device defined by a spherical member 15 having a through-opening 20 concentric with a central axis 22 and two elongated tether members 25 that pass through the through-opening 20. Each elongated tether 25 has a first end 34 secured to a handle 40 and a second end 36 secured to a securement member 45. The handles 40 are provided for being grasped by a coach or a training assistant (not shown). The securement member 45 is provided for securing the batting training device 10 to a stationary object such as a chain-link fence.

Abstract: A practice ball responsive to acceleration for use in practicing sports and an acceleration sensor therefor. The practice ball includes an electronics housing; an acceleration sensor mounted in the electronics housing and responsive to acceleration of the practice ball; a sound generating device also mounted in the electronics housing and responsive to the acceleration sensor; and a soft deformable shell having a shape which simulates a sports ball. The soft deformable shell, which is capable of snugly accommodating the electronics housing, may be supported by a tether line connected to the electronics housing. The acceleration sensor preferably includes at least two switching elements, each of which is responsive to a different magnitude of acceleration. The sound generating device is then responsive to the switching elements so as to emit different programmed sounds depending on which of the switching elements is/are actuated by acceleration of the practice ball.

Abstract: A combination of a glove worn by a user and a ball and stretchable member removably attached to the glove is disclosed. The ball is permanently attached to one end of the stretchable member, and the other end is attached to an anchor which is removably attached to the palm of the glove, so that the user can slap the ball and be assured of its return. The stretchable member is adjustable in size and the ball may be of any desired size and structure. Additionally, the glove may be worn on either hand.
