摘要:
An electronic pen includes a pen body having a longitudinal axis; an image sensor; an ink cartridge replaceably received in the pen body, the ink cartridge having a nib at a first end and an opposite second end; and a force sensor assembly engaged with the second end of the ink cartridge. The force sensor assembly is configured for sensing a nib force transmitted longitudinally axially through the ink cartridge. The pen body includes a removable cover molding extending longitudinally along the pen body for insertion of the ink cartridge inside the pen body.

摘要:
A monolithic integrated circuit comprising an image processor configured to make each of a series of frames of image data available to a host processor, the image processor being configured to receive a first message from the host processor indicative of the host processor not requiring further access to the image data prior to a subsequent frame synchronisation signal; in response to the first message, causing at least part of the integrated circuit to enter a low power mode; and in response to a frame synchronisation signal, cause the part of the integrated circuit in the low power mode to exit the low power mode.
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.

An inkjet printer includes a printhead assembly for ejecting ink upon print media; a capping molding for engaging a face of the printhead assembly; and an actuator for actuating the capping molding against and away from the printhead assembly. The actuator includes a flexible arm attached at one end to the capping molding and at the other end to slip and drive wheels. The slip and drive wheels facilitating actuation of the capping molding via the flexible arm. The flexible arm facilitates conformation of the capping molding against the printhead assembly.
摘要:
There is provided an object comprising: a first identifier identifying a unique object identity; a second identifier identifying a first digital signature for the identity; and a mask for masking at least one of the first identifier and the second identifier. The masked identifier is readable only when said mask has been removed.
