  • Patent number: 10763571
    Abstract: An antenna structure includes a housing and a feeding source. The housing forms a radiating portion, a first coupling portion, and a second coupling portion. The first coupling portion and the second coupling portion are grounded. The feeding source is electrically connected to the radiating portion for feeding current to the radiating portion and divides the radiating portion into a first radiating section and a second radiating section. When the feeding source supplies current, the current flows through the first radiating section and is coupled to the first coupling portion to activate a first operation mode and a second operation mode. When the feeding source supplies current, the current flows through the second radiating section and is coupled to the second coupling portion to activate a third operation mode and a fourth operation mode.

  • Patent number: 9982613
    Abstract: A vehicle includes a first sensor, a second sensor, an engine, a fuel supplying device, and a control device. The control device includes a first sensor detecting unit, a second sensor detecting unit, a vehicle status detecting unit, and a control unit. The control unit is switchable among a regular state, a start-stop enabling state, and an idling-stop state. The control unit switches into the start-stop enabling state from the regular state once the control unit determines that the first sensor and the second sensor are both triggered. The control unit further switches into the idling-stop state and controls the fuel supplying device to stop supplying fuel once the control unit determines that the vehicle status meets an idling-stop condition.

  • Patent number: 8780071
    Abstract: In a capacitive touch panel having touch cells arranged in a two-dimensional array and defined by two coordinates, the present invention provides a third coordinate. In particular, the touch cells in a row are electrically connected a first sensing element and the touch cells in a column are electrically connected in a second sensing element. The first sensing elements can be arranged into two or more touch zones. Each of the touch zones has a zone sensing element for defining the zone coordinate. Some of the first sensing elements in one touch zone are electrically connected to the corresponding first sensing elements in the other touch zones in series. As such, the number of terminals connected to the first sensing elements can be reduced.
