An electronic device, which can enter a debug mode, comprising: a plurality of buttons, wherein a layout of the buttons correspond to one of a first button layout and a second button layout; a processing circuit, configured to control the electronic device to enter a debug mode when at least two of the buttons are pressed to meet a predetermined button combination. The processing circuit controls the electronic device to perform a first test corresponding to the first button layout or to perform a second test corresponding to the second button layout to detect which one of the first button layout and the second button layout does the electronic device correspond to.

A wireless input device includes an information receiving terminal and an information outputting terminal. The information receiving terminal generates a first-portion key. The information outputting terminal receives the first-portion key and generating a second-portion key. An original information is converted into an encrypted information by the information outputting terminal according to the first-portion key, the second-portion key and an encryption algorithm. The encrypted information and the second-portion key are transmitted from the information outputting terminal to the information receiving terminal. The encrypted information is restored to the original information by the information receiving terminal according to the first-portion key, the second-portion key and an encryption algorithm.

A mouse usable as a wheel input device is described. In an embodiment, a mouse may include: a top surface; a touch sensor coupled to the top surface; a controller coupled to the touch sensor; and a memory coupled to the controller, the memory having instructions stored thereon that, upon execution by the controller, cause the mouse to: in response to detection, by the touch sensor, of a force against the top surface: (a) identify a primary click if the force is equal to or greater than a first threshold and smaller than a second threshold, or (b) identify a secondary click if the force is equal to or greater than the second threshold.

A portable device (e.g., a wireless device such as a cell phone) is provided with a flexible keyboard and a flexible display screen. Such flexible components may be stored in the housing of the portable device when not in use. The flexible display screen and flexible keyboard may be expanded from the housing when the flexible components are utilized by a user. Non-flexible display and input components may be provided on the exterior of the portable device such that the device may be used, in some form, while the flexible components are stored. In one embodiment, a portion of the flexible display (or flexible keyboard) may be utilized when the flexible display (or flexible keyboard) is stored in said first housing.

A computer mouse with vibration function includes a base, a press control module disposed on a front portion of the base, a palm support disposed on a rear portion of the base, a vibrator installed on the palm support for receiving the signal from the computer, and a plurality of vibration damping units each of which includes a vibration damper abutting between the palm support and the base. The vibration dampers of the vibration damping units are disposed around the vibrator.

An input device comprises a depressible element with two switches including a first switch configured to generate a first signal when the depressible element is depressed by a threshold distance and a second switch configured to generate a second signal indicating when the depressible element is depressed by the threshold distance and the second switch is in an active state. One or more processors may be configured to receive the first signal from the first switch; configure the second switch to change from an inactive state to an active state in response to receiving the first signal; receive the second signal from the second switch in the active state; determine whether the second signal indicates that the depressible element is depressed by the threshold distance; and generate event data confirming that the depressible element is depressed by the threshold distance in response to receiving the second signal.

A mouse usable as a wheel input device is described. In an embodiment, a mouse may include: a top surface; a touch sensor coupled to the top surface; a controller coupled to the touch sensor; and a memory coupled to the controller, the memory having instructions stored thereon that, upon execution by the controller, cause the mouse to: in response to detection, by the touch sensor, of a force against the top surface: (a) identify a primary click if the force is equal to or greater than a first threshold and smaller than a second threshold, or (b) identify a secondary click if the force is equal to or greater than the second threshold.

In one implementation, a pressure sensitive stylus may receive, at a controller, drawing area coordinates, a stroke pressure from a voltage generated by a piezoelectric crystal, and a stylus coordinate direction from a plurality of fiber optic sensors, determine a drawing area from a wireless signal frequency corresponding to the drawing area coordinates, determine a drawing mode of a stylus stroke, wherein the drawing mode includes a stylus coordinate direction and a stylus stroke type, and transmit the drawing area and the stylus stroke.

A mouse usable as a wheel input device is described. In an embodiment, a mouse may include: a top surface; a sensor coupled to the top surface; a controller coupled to the sensor; and a memory coupled to the controller, the memory having instructions stored thereon that, upon execution by the controller, cause the mouse to: enter a mouse mode of operation in response to detection of a finger on the top surface; and enter a wheel mode of operation in response to detection of a turning of the mouse in a clockwise or counterclockwise direction.

A roller wheel module includes a roller wheel, an elastic member, and an adjustment assembly. The roller wheel includes a ratchet structure and has a configuration surface. The configuration surface is divided into a blank region and a ratchet region. The ratchet structure is disposed on the configuration surface and is located in the ratchet region. The elastic member is disposed next to the roller wheel and has a first end and a second end opposite to each other. The first end of the elastic member is connected to the adjustment assembly, and the adjustment assembly drives the second end of the elastic member to move between the blank region and the ratchet region. The roller wheel module allows the user to switch between a ratchet rotating mode and a smooth rolling mode according to requirements, and allows the user to quickly scrolling and have a better touch feel.
