| 20090167610 | Patch antenna and method of making the same - A patch antenna includes: a dielectric layer made of an insulation material, and having upper and lower surfaces, and a through hole; a radiation metal layer disposed on the upper surface of the dielectric layer, and having a first plate body, a first aperture aligned with the through hole, and a first protruding portion extending from a peripheral edge of the first aperture into the through hole; and a grounding metal layer disposed on the lower surface of the dielectric layer, and having a second plate body, a second aperture aligned with the through hole, and a second protruding portion extending from a peripheral edge of the second aperture into the through hole. The first and second protruding portions contact each other in the through hole so that the radiation and grounding metal layers are electrically connected. A method of making a patch antenna is also disclosed. | 07-02-2009 |

| 20090040761 | Acoustic wave induced light emitting golf ball - A light emitting golf ball is provided that includes a spherical housing, a fixing container, a light emitting device, a first fitting portion, and a second fitting portion. The light emitting device is disposed in the fixing container and includes an acoustic wave sensor, a controller, one or more light emitting elements and an electricity supplier. When the acoustic wave sensor receives an external acoustic wave signal higher than a predetermined value, it sends out an activating signal to the controller so that at least one light emitting element emits light. This invention is irrelevant to the hitting direction. It has an extremely low defective rate. Furthermore, the product life can be prolonged. | 02-12-2009 |
| 20110126446 | Mouse trap having retractable biting portions - This invention relates to a mouse trap having retractable biting portions. It includes a base, a movable portion, and a trigger. The base has a front seat which has a lower outer edge and several receiving holes. The movable portion is disposed on the base and has a front frame portion and a restoring force generating element. The front frame portion is disposed with an upper outer edge and a plurality of retractable biting portions. These retractable biting portions are corresponding to the receiving holes. The restoring force generating element is able to urge the movable portion moving from the first position to the second position. So, it can capture a mouse quickly. The protruded length of each retractable biting portion is automatically adjusted. Hence, the captured mouse will not bleed so it is sanitary. The capture method is humane without sacrificing its capturing result. The safety of the product can be enhanced. Plus, the biting depth is automatically adjusted. | 06-02-2011 |
