Abstract: An image scanning device includes an upper shell, a feeding shaft pivotally connected to the upper shell, a feeding roller mounted around the feeding shaft, a sensing roller, a motor, a lower shell pivotally covered to the upper shell, a plurality of springs and a contact image sensor. The sensing roller is mounted around the feeding shaft. The motor is connected with the feeding shaft. The motor drives the feeding shaft to rotate in different speeds. The plurality of the springs are mounted to the lower shell. The contact image sensor is mounted to the plurality of the springs. A top surface of the contact image sensor is capable of abutting against lower portions of outer surfaces of the feeding roller and the sensing roller by virtue of the plurality of the springs elastically abutting against a bottom surface of the contact image sensor.

Abstract: The invention provides a gym system including a plurality of stationary devices. The plurality of stationary devices is configured to establish a host monitor zone for exchanging received signal strength indicator (RSSI) values from at least one exercise portable sensor of exercise portable sensors, thereby avoiding the wireless pairing fails. The at least one of the stationary devices process the RSSI values under the host monitor zone to determine a distance status in relation to a location between the at least one exercise portable sensor and the at least one of the stationary devices to avoid the wireless pairing fails between the at least one exercise portable sensor and the at least one stationary device, so that the at least one exercise portable sensor is paired with a corresponding one of the stationary devices in a stationary device-specific exercise area.

Abstract: An adjustable scanning device includes a base, a first contact sensor mounted to the base and exposed to a top surface of the base, a cover mounted on the base and located above the first contact sensor, and a second contact sensor. The second contact sensor is movably mounted to the cover up and down, and exposed to a bottom surface of the cover. The second contact sensor is located over the first contact sensor to form an adjustable scanning path located between the second contact sensor and the first contact sensor. A width of the adjustable scanning path is adjustable.

Abstract: The present invention provides an apparatus for controlling an electronic stop watch. The apparatus comprises a controller and a transmission media. The controller includes a keyboard for inputting a datum and an output port outputting the datum to the electronic stopwatch. The transmission media connects the electronic stopwatch with the controller, through one of a wire connection and a wireless connection.
