Implementations of a portable racetrack are provided. In some implementations, the portable racetrack comprises a foldable board comprising a plurality of holes configured to secure accessories to the board. In some implementations, the portable racetrack further comprises detachable guard rails operatively attached to the foldable board using the holes. In some implementations, the portable racetrack includes no mechanism on the foldable board to guide a remote control car that is operated on the racetrack except the guard rails so that the remote control car may freely travel on the racetrack.

Provided is a communication system including a controller installed on a hand of a user, an operation target remotely operated by the controller, and a relay apparatus that performs relaying between the controller and the operation target, in which the controller includes a first detection section that detects a motion of fingers of the user, a stimulus providing section that provides an external stimulus to the fingers of the user, and a control section that controls the stimulus providing section, the operation target includes a driving section that performs an action in reference to action information received, and a second detection section that detects the external stimulus to the operation target, and the relay apparatus transmits, to the operation target, the action information based on a detection result from the first detection section, and in reference to a detection result from the second detection section, transmits, to the controller, stimulus provision information for controlling the stimulus providing section to provide an external stimulus to the user.

Embodiments herein use multiple different transmission modes of a line-of-sight (LOS) communication system (e.g., an infrared (IR) or visible light communicate system) to simulate user actions that correspond to different distancese.g., a melee attack versus a ranged attack. A toy device may include various sensors that detect user motion which is then used to identify a user action. If the user action is a melee attack, then the attack should affect only targets that are close to the toy device. To simulate this difference between user actions, the toy device uses a first LOS transmission mode which may have a limited range to send an instruction to a target device. Conversely, if the user action is a ranged attack, then the toy device uses a second LOS transmission mode which has a greater range than the first LOS transmission mode to send the instruction.

The present invention provides a sensing control system for an electric toy, characterized in that it comprises a signal detection module for receiving an external sensing and then generating a sensing signal; a calculation and control module for receiving the sensing signal and counting a number of the sensing signal, and then sending out different control signals corresponding to different numbers of the sensing signals; and an electric driving module for receiving the control signal and then sending a driving signal to the electric toy, so as to control the electric toy to work. Therefore, according to different numbers of sensing signals, the electric toy is able to perform different actions or speed changes of the same action. In this way, the toy equipped with the sensing control system of the present invention can go beyond the limitation of a remote control, and thus becomes suitable as a toy for children of different ages. In addition, it makes a toy gain advantages of becoming more user friendly, more interactive, more interesting, and thus would become many children's favorite.

A toy is represented on a website via a virtual replica of the product. The toy has a registration data associated with it that is electronically stored in the toy using an electronic storage medium. A user is registered on the website by associating the user with a user ID. The user ID is associated with the virtual replica of the product by utilizing the registration data. Access is granted to one or more features on the website in connection with the virtual replica of the product subsequent to input and validation of the registration code via the user ID without requiring additional entry of the registration data.

A prompt drop device for a remote control model airplane comprises an airplane body (1) and a horizontal tail (3). A support (2) disposed on the airplane body (1) is used for supporting the front end of the horizontal tail (3). The front end (8) of the horizontal tail (3) is rotated under the binding of the support (2). A driving device is connected with the horizontal tail (3) and is used for lifting the rear end of the horizontal tail (3). A remote control model airplane comprising the prompt drop device is provided with the movable horizontal tail (3) and controls the angle of the horizontal tail (3) during landing, so that vertical descending is realized, and damage during landing is avoided.
