  • Patent number: 10328597
    Abstract: A cutting mat includes two baseboards, at least one foldable sheet connecting the two baseboards and multiple back antiskid units. Each baseboard has a cutting surface formed on a front thereof and a back, wherein the two baseboards are adjacent to each other and the foldable sheet is attached to the back of each of the two baseboards for connecting the two adjacent baseboards. The foldable sheet has a pre-folding line formed thereon along an abutment between the two adjacent baseboards such that the foldable sheet is folded along the pre-folding line to make the two baseboards completely abutting each other. The multiple back antiskid units are formed by printed antiskid layers that are distributed on the back of each of the two baseboards and a back of the foldable sheet.

  • Patent number: 9547224
    Abstract: A projector includes an apparatus casing, a light source module, a flow generating device, a sensing module, and a power module. The light source module is disposed inside the apparatus casing and includes a light-emitting part and a lampshade surrounding the light-emitting part. The flow generating device can generate an air flow for dissipating heat by the light source module. The sensing module is disposed in the apparatus casing and includes a thermo-sensitive component disposed near the lampshade and located in a flowing path of the air flow. The power module is disposed in the apparatus casing and electrically connected to the light source module and the sensing module. The power module selectively stops powering the light source module according to an electric parameter of the thermo-sensitive component.
