摘要： An embodiment of the invention relates to a method for sensing a displacement of a pointing device, like a mouse. The pointing device includes at least one light source configured to illuminate a surface, at least one first secondary photodetector, at least one second secondary photodetector and at least one primary photodetector. Each individual value of photodetectors is weighted and compared to sense the displacement of the pointing device by comparing a plurality of storage elements.

摘要： Provided is a gate controller having a primary signal input which is AC coupled to the gate through a capacitor, one or more bias inputs each connected to the gate through a resistor such as to control the DC voltage bias of the gate and therefore the conductivity o the switching element. The bias inputs can be properly connected to internal nodes of the charge pump, or charge pump stages, such that the gate controller is self-biased, without using bias-reference external to the charge pump. The gate controller is programmable by using potentiometers in place of the bias resistors. The programmable gate controller stages can be connected to form a programmable gate controlled charge pump

摘要： The present disclosure relates to a NFC communication system, to a method of establishing communication between a wireless communication device and a passive NFC device and to a passive NFC device. The passive NFC device includes an NFC controller, an NFC transceiver coupled with the NFC controller, and at least one persistent flag coupled with the NFC controller, the persistent flag being switchable between an activated state and a deactivated state. The NFC controller is configured to perform a logical operation being divisible into a sequence of at least a first subtask and a second subtask and the NFC controller is configured to ascertain the status of the persistent flag. The NFC controller is further configured to selectively perform at least one of the first subtask and the second subtask on the basis of the status of the persistent flag.
