A board to board connector includes a first male connector and a second male connector. The first male connector includes a first number of pins. The second male connector is aligned with the first male connector and includes a second number of pins. The first male connector is configured to be removably electrically coupled to a first female connector including a third number of pins equal to the first number and the second male connector is configured to be removably electrically coupled to a second female connector including a fourth number of pins equal to the second number. The first male connector and the second male connector are also configured to be removably electrically coupled to a single third female connector including a fifth number of pins equal to the first number plus the second number.

An example apparatus to retain a computer power brick in a power brick holder includes a plate and a positioning mechanism removably attached at any of a plurality of positions on the plate. The positioning mechanism is attached at a preset position on the plate based on a size of the power brick.

Plates to retain power bricks

Example thermal modules are disclosed. An example thermal module for use with an electronic device includes a first heatsink defining a first airflow exit. The first heatsink including a first set of fins having a first height and a second set of fins having a second height. The second height being less than the first height. The second set of fins being adjacent the first airflow exit. A second heatsink defines a second airflow exit. The second heatsink is spaced from the first heatsink to form a gap therebetween. The second heatsink is thermally coupled to the first heatsink via a heat pipe.

Thermal modules for electronic devices

A touch pen for a capacitive touch screen is provided. The touch pen includes a signal receiver conductor, a signal detecting and adjusting circuit, and a signal transmitter conductor. The signal receiver conductor receives a first touch signal from the capacitive touch screen. The signal detecting and adjusting circuit enlarges the first touch signal to a second touch signal having a standard intensity with a first magnification factor, a second magnification factor and a third magnification factor. The signal transmitter conductor issues the second touch signal to the capacitive touch screen. According to the second touch signal, the capacitive touch screen senses a position of a touch point of the touch pen.

Touch pen

A touchpad controlling method and a touch device using such a method are provided. The touch device is applied to an electronic appliance. The touch device includes a touchpad and a coordinate transformation program. The touchpad is used for detecting a number of touching points in response to the touching gesture on the touchpad and the position of each touching point. If the number of touching points is equal to 1, the electronic appliance is operated in a relative coordinate mode. Whereas, if the number of touching points is greater than 1, the electronic appliance is operated in an absolute coordinate mode.

Touchpad controlling method and touch device using such method

The present invention provides a power-saving laser pointer mouse including a battery, a micro-controller and a laser diode. The power-saving laser pointer mouse can be operated in multi-stage power-saving modes according to the voltage value of the battery. The lighting time interval of the laser diode is adjusted by the micro-controller according to the voltage value of the battery. When the voltage value of the battery is reduced, the lighting time interval of the laser diode is shortened so as to achieve the power-saving purpose.
