Abstract: Instead of allowing an electrostatic discharge (ESD) event to cause a lost clock signal sync due effects of the ESD event causing an SSD to enter low power mode, utilizing ESD detection can be used to stop the reference clock signal to avoid involuntary low power mode. When an ESD event occurs, an ESD antenna sensor will selectivity disable sensitive signals and the reference clock signal. Once the ESD detector recognizes an ESD event has occurred, the device is able to enter freeze mode. While the reference clock signal is in freeze mode, the input signals are bypassed to avoid lost clock signal sync. Once the ESD event is done, the controller notifies the host to restart the reference clock signal and resume clock signal sync.

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: Systems and methods for devices connected by a control bus to share configuration data for accelerating physical link negotiation for a peripheral interface are described. Computer devices, such as data storage devices, may include a peripheral interface configured to connect to a host system and a control bus interface to connect to a control bus. Other devices on the same control bus may establish peer communication through the control bus interface to share configuration data, such as coefficients for physical link negotiation of the peripheral interface. To accelerate reestablishing communication through the peripheral interface, the device may receive previously stored configuration data from another device over the control bus.

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.
