Patents by Inventor Lewis Ka Hang Cheng

Lewis Ka Hang Cheng has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11608953
    Abstract: A method for simulating a candle flame with at least one computing device. The method may include controlling at least one lighting element according to at least a current wind value and a current flame value. The method may include controlling the current wind value and the current flame value by iteratively determining whether a first event occurred. When the first event is determined to have occurred, the method may include setting the current wind value to a random wind value and then changing the current wind value toward a baseline wind value. When the first event is determined to have not occurred, the method may include changing the current wind value toward the baseline wind value, determining whether a second event occurred. When the second event is determined to have occurred, the method may include setting the current flame value to a random flame value.

  • Publication number: 20220163177
    Abstract: A flame simulation method including: identifying, by a computing device, a maximum brightness level value and a primary event generation level; setting, in response to determining that a first event occurred based on the primary event generation level, a secondary event generation level; adjusting the secondary event generation level towards a baseline secondary event generation level; adjusting a current brightness value of a lighting element of a flame simulation apparatus towards the maximum brightness level value; setting, in response to determining that a second event occurred based on the secondary event generation level, the current brightness level value of the lighting element to a value less than the maximum brightness level; and controlling, by the computing device, a brightness level of the lighting element to correspond to the current brightness level value of the lighting element.

  • Patent number: 10479597
    Abstract: The disclosed systems and methods relate to improved tamper-proof cases for securely storing and shipping products. In one example, a tamper-proof case comprises a unibody frame constructed from a single piece of material. The unibody frame can comprise six sides and include one or more living hinges that allow the unibody frame to fold into a completed case. Various sides can be configured to receive panels to give the crate additional structure, rigidity, and security. Additionally, the frame can comprise a split-top lid with a self-locking mechanism with a tamper-proof pull tab for opening the lid.
