The present invention relates to a hollowed ball with an erratic movement for pets formed by a single piece, preferably made from an elastic material that allows the erratic movement during a rotation or rebound displacement due to its interior design. The form and dimensions and dimensions of the ball allows the storage of food in its interior, introducing and dosing such food through openings or hollows placed in the external part of the ball. The ball is structurally formed in its interior by at least two cylindrical sections with continuing radially arched thickness with a sequential projection of horizontally cylindrical truncated steps.

Implementations described and claimed herein provide systems and methods for interactive fetching for one or more participants, such as pets. In one implementation, a projectile, such as a ball, is received in a receiver and transported through an opening into a feeder of a randomizer. One of a plurality of chutes is randomly selected using gravity, and the projectile is transported from the feeder into the selected chute. The chute generates a smooth roll along a ramp to a port, from which the projectile is ejected along an ejection path for the participant to retrieve.

Many headset devices, such as virtual reality helmets, present visuals that respond to the user's motion, such that a rotation of the user's head causes the visual to be re-rendered from a correspondingly rotated perspective. The lag between the user's motion and the updated rendering from the new perspective may be perceivable even at high framerates, and may induce unpleasant feelings such as vertigo. Instead, headset devices may respond to detected motion by identifying a displacement of the physical location of the visual that causes it to maintain a physical position relative to a stationary reference point. The display is operatively coupled with a displacer, such as actuators or a projection adjustment, that are engaged to displace the display according to the identified displacement and maintain a physical location of the visual relative to the stationary reference point (e.g., until the visual is re-rendered from the updated perspective).

A device including a visual or audible 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 is disclosed. The device may be used as a toy for amusement, and may be shaped like a play ball or as a handheld unit. The device may be powered from a battery, which may be charged from an AC power 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 the sensed acceleration magnitude or direction, such as sensing the crossing 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.

A boxing training device (1) for using with a punching bag (31) includes at least one sensor (61) to measure punches, feedback equipment (5) for giving feedback to a user, and control equipment (6) for controlling the device. The device further includes signalling equipment (4) in order to give signals to the user, a central processing unit (3), a power source (66) and a belt (2) including pockets (9, 10).

A balance and/or gait perturbation system is disclosed herein. The balance and/or gait perturbation system includes a balance and/or gait perturbation device, at least one visual display device having an output screen, and one or more data processing devices. The one or more data processing devices are operatively coupled to the balance and/or gait perturbation device and the at least one visual display device, the one or more data processing devices are configured to generate a stochastic signal for controlling a display parameter of one or more scenes on the output screen of the at least one visual display device, and the one or more data processing devices are further configured to display the one or more scenes on the output screen of the at least one visual display device using the stochastic signal such that the one or more scenes perturb a balance and/or gait of the person.

Interactive system provides training and assessments relating to joint stabilization capabilities and reaction-based performance for diverse populations. This system may enhance the subject's ability to generate and deliver power as a direct byproduct of properly timed decelerations originating with the effectors and supported by the verticality of the spine. Said decelerations also provide functional means for improving joint stabilization capabilities via improved co-contraction of the shoulder(s) joints and other anatomical locations on the subject. The resulting data may serve as the basis for predictive analytics relating to joint stabilization and the associated risk of orthopedic injuries. This system may also train/improve the dampening of internal forces resulting from aggressive weight bearing movements, and more effectively dissipate the force of received physical impacts.

The invention relates to a device for training coordinative faculties. The device has at least one movable standing plate; at least one static base plate; at least two connecting elements, the height of which can be modified and which act between the at least one movable standing plate and the at least one static base plate, a user interface; and a control element. The device is designed to specify a sequence of various setpoint positions of the centre of gravity of a user standing on the at least one movable standing plate, each of the setpoint positions being specified for a determined duration, and to continuously measure the actual position of the centre of gravity of the person standing on the moving plate. The device is further designed to compare each measured actual position to the setpoint position specified at the time of the measurement, to generate control signals taking into consideration the measured actual positions and/or the results of the comparisons of actual positions and setpoint positions, and to control the at least two connecting elements with the control signals.
