Abstract: A digital-currency-based method for vote counting includes a vote-counting procedure that includes steps of computing a number of newly-added votes based at least on an amount in a digital currency indicated by a piece of vote data, determining whether the piece of vote data was obtained during an ending portion, determining whether a voter identifier indicated by the piece of vote data has been recorded in at least a number N of data blocks when the piece of vote data was obtained during the ending portion, performing an adjustment procedure to adjust the number of newly-added votes when the voter identifier has been recorded in the number N of data blocks, reading a vote number, and computing a total number of votes based on the vote number and the number of newly-added votes.

Abstract: A navigation system adapted to be installed on a vehicle includes an output device and a processing device. The processing device executes the following steps after determining a planned route: obtaining real-time image data and performing image recognition on the image data to identify at least one lane from the image data; obtaining a real-time positioning result that indicates a current location of the navigation system; based on the planned route and the positioning result, selecting a target lane that corresponds to a moving directive presented by the planned route; and controlling the output device to visually output a route indicator that indicates the target lane.

Abstract: A navigation system includes a processing unit connected to a storage device for fetching and executing a navigation program to: determine a planned route; obtain a real-time image and real-time positioning data indicating a current location of the system; perform image recognition on the image, and determine whether a specific object exists in the image; determine whether a route adjustment condition is met based on the planned route, the positioning data and result of the determination; and adjust the planned route when the route adjustment condition is met. The route adjustment condition includes that a meaning conveyed by the specific object is in conflict with the planned route.

Abstract: A distance sensing system includes a first electronic device and a second electronic device. A second processing unit of the second electronic device sends a wireless signal via a second short-range wireless communication unit. When a first processing unit of the first electronic device receives, via a first short-range wireless communication unit, the wireless signal from the second electronic device, the processing unit generates an estimated distance value indicating an estimated distance between the first electronic device and the second electronic device based on signal strength of the wireless signal. When the first processing unit of the first electronic device determines that the estimated distance value is less than a predetermined distance, the first processing unit outputs a notification via the first output unit, so as to send the notification to a user of the first electronic device when the second electronic device is close to the first electronic device.
