Described herein are wireless billiard ball devices comprising a spherical housing and a circuit board mounted within the spherical housing, the circuit board having components for measuring the impact location of a billiard cue strike upon the surface of the spherical housing in reference to the relative orientation of the device with respect to gravity. The devices described herein do not require manual alignment by a player to measure impact location data. In other embodiments, the spherical housing is comprised of a bored hole, a potting material, and a circuit board mounted within the bored hole and secured in place with the potting material, the circuit board having components for measuring the impact location of a billiard cue strike upon the surface of the spherical housing in reference to the relative orientation of the device with respect to gravity.

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.

A golf ball is disclosed herein that includes at least one radar detectable mark such that a projected pattern is formed when the at least one radar detectable mark is radially projected onto an outer surface of the golf ball. The projected pattern can have a first wave profile mapped along a path defined by a first spherical arc on the outer surface of the golf ball. The projected pattern can comprise at least one first crest and at least one first trough. The projected pattern can have a periodic function selected from: a sine wave, a sawtooth wave, a triangle wave, or a square wave.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

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.

An electronic sideline marker for use in football comprises a first display configured to display an indication of a down and a second display configured to display one or more timers. The second display may be configured to display a play clock, a go-clock, and/or a throw-clock. A play clock may first be displayed, and the marker may then receive an indication (e.g., a button press) that the football has been snapped, at which point display of the play clock may be replaced with display of a go-clock. The marker may be configured to output indications when the play clock, go-clock, and/or throw-clock expire. The marker may be configured to electronically communicate with one or more other markers for use in the football game, or one or more other remote electronic devices such as sensors in flag football belts, flags, and/or footballs.

A game device for converting a container into a game figure to simulate an interactive game includes a container cover, a sensor, and a transmitter. The container cover is removably attached to the container and has the shape of the game figure. The sensor is disposed relative to the container cover and is configured to (i) detect interaction of a game object with at least one of the container and the container cover and (ii) generate a signal in response to the detection. The transmitter is configured to receive the signal from the sensor, and to wirelessly transmit the signal to at least one sensory feedback device to provide sensory feedback to a user. A game system includes the game device, a wirelessly connected sensory feedback device, a computer, and software executing on the computer.

The present disclosure provides a wireless signal transmitting ball to be used in practice or gameplay of a sport and/or other entertainment activities. The ball of the disclosure comprises a microprocessor unit configured to record, process, and transmit data to a paired device. Further disclosed is a method of actuating the ball between different modes. The ball could be used by players during practice to record data about their performance. The ball could also be used by players or game officials or referees to keep score, adjudicate and decide the gameplay. For example, the information about location of the ball could be used to track balls that could potentially be lost. Additionally, data about spin, trajectory, speed, force applied and the like could be used by players or broadcasters for gaining insights to add to viewing pleasure.

The LED light and sound ball for emergency responders is activated upon contact after being fired from a launcher to illuminate and direct responders to an area of interest, such as a potential crime scene. The ball includes a clear polymeric, spherical outer casing, and a rectangular, clear inner casing having a circuit board mounted therein. A plurality of rig rods extend through the inner casing and include curved heads that are in close proximity to the inner surface of the spherical outer casing. Upon impact, the outer casing flexes and pushes against one of the curved heads and pushes its associated rig rod inward, thereby closing a contact that triggers a control circuit to continuously illuminate a plurality of bright LEDs and continuously activate a sound generator that emits a foghorn-type alarm. The LED light and sound ball may be thrown or fired from a conventional compressed air launcher.
