Abstract: The present disclosure generally relates to reducing link-up time between an upstream device and a downstream device. Rather than re-coordinating the link between devices each time, knowledge gained from a previous link-up is used to speed up the link-up. Typically, when both the upstream device and the downstream device have not changed, then the coefficient values for downstream port (DSP) transmission (Tx) equilibrium (EQ) that resulted in a desired bit error rate (BER) should not have changed either. Hence, rather than exchanging coefficients, the previous values can be reused with confidence eliminating the need to exchange coefficients. In so doing, the link-up process is much faster and system resources are not wasted on unnecessary coefficient exchanges.

Abstract: There is provided a method (700) of touch screen input detection comprising the steps of detecting an initial touch event on a touch sensor (720); detecting a change in the detected touch event; and determining (770) that the change in the touch event is due to a further touch on the touch sensor whilst the initial touch event is maintained. An electronic device is also described.

Abstract: A Hand Held Computing device (HHC) (180) incorporating a keypad function (120), a display function (100) and processing function (430), the processing function (430) being operably coupled to both the keypad (120) and display (100) functions. The keypad function (120) is of a modular construction, such that a removable key-holder (300) may be de-coupled from the device (180), rotated, and re-assembled to the device (180) in a different orientation (230, 210), the keypad function being operable in this new orientation.
