Abstract: A method for automatic adjustment of a pedelec having a first assist level and a second assist level includes the following steps. The pedelec is operated at an initial assist level. A pedal torque index is measured and compared with a predetermined numeric section having an upper threshold and a lower threshold. If the pedal torque index is within the predetermined numeric section, the pedelec is kept in operating at the initial assist level. If the pedal torque index is lower than the lower threshold, the pedelec is adjusted to operate at the second assist level. If the pedal torque index is higher than the upper threshold, the pedelec is adjusted to operate at the first assist level. Therein, auxiliary force provided by the pedelec at the second assist level is less than auxiliary force provided by the pedelec at the first assist level.

Abstract: An electronic device includes a first shell body, a second shell body, and a third shell body. A second side edge of the second shell body is pivotally disposed at a first side edge of the first shell body, and the second shell body pivotally rotates relative to the first shell body in a first axial direction. A third surface of the third shell body is attached to and pivotally disposed at a second surface of the second shell body. The third shell body pivotally rotates relative to the second shell body in a second axial direction, and the second axial direction intersects the first axial direction. Accordingly, the electronic device presents two use types for convenient use.

Abstract: A mouse with a built-in laser pointer including a mouse body, a first holding portion, a second holding portion, a laser source and a laser-emitting button is provided. Both the first holding portion and the second holding portion are pivotally connected to the mouse body. The laser source is disposed on either the first or the second holding portion. The laser-emitting button disposed on one of the mouse body, the first and the second holding portions activates the laser source. When the first and the second holding portions are parallel, the mouse with a built-in laser pointer controls a cursor's movement on a computer screen. When the first holding portion and the second holding portion are relatively open, the user can hold either the first or the second holding portion for operating the laser-emitting button for the laser source to emit laser beams.

Abstract: A signal input apparatus includes a hand-held device and a receiving device. The hand-held device includes a sensor for outputting a signal, a first data port coupled to the sensor, and a wireless signal transmitter coupled to the sensor. The receiving device includes a second data port and a wireless signal receiver. When the receiving device and the hand-held device are separated, the hand-held device outputs the signal through the wireless signal transmitter, and the receiving device receives the signal through the wireless signal receiver. When the receiving device and the hand-held device are integrated, the first data port and the second data port are electrically connected, the hand-held device outputs the signal through the first data port and the receiving device receives the signal through the second data port.

Abstract: A foldable computer mouse including a mouse body, a sensor and an extension part is disclosed. The bottom of the mouse body includes a receiving space and a contact surface, and the sensor is disposed on the contact surface of the bottom of the mouse body. The extension part is pivotally connected to one side of the mouse body and adjacent to the receiving space. When the extension part rotates outwards to a predetermined location, the contact surface between the foldable computer mouse and users is increased. Yet when the extension part rotates inwards to the inside of the receiving space, the size of the foldable computer mouse is reduced for easy storage. When the extension part rotates outwards to the predetermined location, users can operate the foldable computer mouse, and when the extension part rotates inside the receiving space, users can operate the foldable computer mouse as well.

Abstract: A handheld electronic apparatus. The handheld electronic apparatus includes a first connecting member, a second connecting member, an operating member, a first holding member and a second holding member. The second connecting member is rotatably connected to the first connecting member. The operating member is rotatably connected to the second connecting member. The first holding member is rotatably connected to the first connecting member. The second holding member is rotatably connected to the first connecting member. The first and second holding members relatively rotate between a closed position and an open position. The invention thereby provides convenient use of communication, digital photography, PDA, and video game functions in a single device.

Abstract: A dual mode computer mouse including a first mouse body and a second mouse body is disclosed. The first mouse body includes a first sensor, a first button and at least a second button. A second sensor is disposed either in the first or the second mouse body. The second mouse body includes a third button and is hinged to one tail end of the first mouse body. The first mouse body and the second mouse body can rotate relatively. When the dual mode computer mouse is in a palm-type configuration, the first button and, third button and the second sensor are activated. When the dual mode computer mouse forms a pen-type configuration, the third button is activated and the first sensor is in an activated state.

Abstract: A projector and a supporting structure thereof are provided. The projector includes a main body and a supporting structure. The supporting structure is disposed at the main body. The supporting structure includes a sliding element and an elastic element. The sliding element is supported on a plane and can move backward and forward with respect to the main body. The elastic element has a first end and a second end. The first end is coupled to the sliding element, and the second end is coupled to the main body. The elastic element generates a substantially constant elastic force when the elastic element is deformed. As the sliding element moves with respect to the main body, the elastic force balances against the gravity force of the main body, such that the elevational angle of the main body with respect to the plane is changed.

Abstract: Cups and a method for stacking the same. A cup comprises a plurality of feet, and a plurality of cuts are formed between each foot. The shape of the feet and the shape of the cuts are complementary. By joining the feet of the first cup and the cuts of the second cup, the feet of the first cup and the cuts of the second cup are securely joined.

Abstract: A mouse device includes a mouse body and a scrolling wheel. The mouse body has a front curved surface, a rear curved surface and a bottom. The bevel and a rear edge of the front curved surface are respectively connected to the bottom and the rear curved surface. The included angle of the front curved surface and the bottom is between 45 and 70 degrees. The scrolling wheel is disposed on the bevel. When operating the mouse device, the user uses an index finger and a portion connecting the index finger and the palm to form an arch atop of the front curved surface and the rear curved surface, thus the mouse body is largely under the index finger. The user can tilt the mouse body for the first scrolling wheel to contact with a working surface and scroll a monitor's screen frame.
