    摘要： A force sensor assembly particularly suited for use in an electronic stylus that senses the contact force on its nib for recording pen strokes and handwriting recognition. The sensor assembly has a housing in which force sensing circuitry is mounted. The force sensing circuitry is configured for receiving an input force to be sensed and converting the input force into an output signal indicative of the input force. A coupling transmits the input force to the force sensing circuitry. The coupling has an inner section that applies the input force to the load bearing member, an outer section that receives the contact force on the nib and a collapsible section that allows the outer section to move relative to the inner section when the contact force exceeds a threshold. The relative movement of the outer section is limited by an abutment on the housing so that the input force on the force sensing circuitry never exceeds the threshold. This protects the force sensing circuitry from damage by sharp impact loads such as dropping the stylus on its nib.

    摘要： A force sensor particularly suited for use in an electronic stylus that senses the contact force on its nib for recording pen strokes and handwriting recognition. The sensor has a housing for a load beating member for receiving an input force to be sensed and associated circuitry for converting the input force into an output signal indicative of the input force. A coupling transmits the input force to the load bearing member. The coupling has an inner section for transmitting the input force to the load beating member, an outer section for receiving an applied contact force and a collapsible section for allowing the outer section to move relative to the inner section when the contact force exceeds a threshold. This protects the force sensor from damage by sharp impact loads such as dropping the stylus on its nib.

    摘要： A photodetecting circuit is disclosed which includes a photodetector for generating a signal in response to incident light, a storage node, transfer and reset transistors and an output circuit. The storage node has first and second node terminals. The second node terminal is connected to a compensation signal during a read period of the photodetection circuit. The transfer transistor is disposed intermediate the first node terminal of the storage node and the photodetector and is for electrically connecting the first node terminal and the photodetector during an integration period upon receiving a transfer signal to a gate of the transfer transistor, allowing charge stored in the storage node to change based on the signal of the photodetector. The reset transistor has a control node for receiving a reset signal, a first terminal for receiving a reset voltage, and a second terminal electrically connected to the first node terminal, such that the reset voltage is supplied to the first node terminal when the reset signal is asserted at a gate of the reset transistor. The output circuit generates an output signal during the read period of the photodetecting circuit. The output signal is at least partially based on a voltage at the first terminal. The compensation signal is a logically negated version of the transfer signal.
