  • Patent number: 10543420
    Abstract: A prompting device for prompting state information of a physical game character includes a smog machine and a control circuit. The smog machine include a smog chamber, a heating element, and an air-blowing device. The smog chamber has a receiving cavity for receiving smog fluid, an inlet, and an outlet. The inlet and the outlet are in communication with the receiving cavity. The heating element is mounted within the receiving cavity and generates heat to vaporize the smog fluid after an electric current is applied. The air-blowing device is disposed corresponding to the outlet for blowing an air flow towards the receiving cavity. The air flow generated by the air-blowing device enters into the receiving cavity from the inlet and discharges smog within the receiving cavity from outlet. The control circuit is configured to control the smog machine to generate the smog that characterizes the state information.

  • Publication number: 20170158331
    Abstract: An apparatus and kit for assembling a mobile platform and methods for making and using the same. When associated with a mobile platform, a power device can be installed outside a control device coupled with the mobile platform. The power device can be located outside a housing enclosing the mobile platform and exposed to an external operating environment of the mobile platform. Heat generated by the power device can be dissipated without installation of additional cooling equipment. The power device and the control device can thus have lower operating temperatures and longer lifetimes. The power device can be installed on a module associated with the mobile platform for further improving heat dissipation of the power device. The module optionally can function as a shock absorber for preventing damage to the power device in case the mobile platform is involved in a crash.

  • Publication number: 20170070125
    Abstract: A system and kit for dissipating heat generated by a motor assembly and methods for manufacturing and using same. The motor assembly includes a housing that defines an internal chamber. The internal chamber communicates with an air inlet and an air outlet each being formed in the housing, and can at least partially receive motor inner workings. A pump assembly can be included in the internal chamber for generating an air flow during operation of the motor assembly. The pump assembly can draw air into the internal chamber via the air inlet, generating an air flow within the internal chamber. The air drawn into the internal chamber is applied to the motor inner workings, and the air heated by the motor inner workings is expelled from the internal chamber via the air outlet. Thereby, the air flow advantageously can cool the motor assembly as the air traverses the internal chamber.
