Abstract: A slat angle adjustment mechanism for Venetian blind includes a body shell and a transmission unit including a transmission gear set and retractable member. The transmission gear set includes a gear having a position-limiting hole corresponding a second through hole of the body shell, and a screw rod with an extension shank. The retractable member is connected to and movable back and forth along the extension shank of the screw rod. When pulling the retractable member, the retractable member is moved along the extension shank of the screw rod from a first position; when pushing the retractable member, the retractable member is moved along the extension shank of the screw rod from the second position back to the first position. Thus, subject to the retractable characteristic, the slat angle adjustment mechanism prevents damage during packaging.

Abstract: An input protection circuit includes a current detection circuit, a voltage detection circuit, a latch circuit and an output circuit. The current detection circuit receives a power input, and when an input current exceeds a threshold current, the current detection circuit outputs a control current. The voltage detection circuit is coupled to the current detection circuit, and when the input voltage exceeds a threshold voltage, the voltage detection circuit outputs a control voltage.

Abstract: A method for reading/writing a chip in a USB type-C cable comprises converting a read/write command into unstructured vendor defined message (UVDM) that is conforming to a USB power delivery specification. Such UVDM will be delivered to the chip via a type-C configuration channel interface. The chip analyzes the UVDM to acquire the read/write command and reads or modifies the content of a non-volatile memory in the chip according to the read/write command. Due to use of the type-C configuration channel interface, which is inherent in the USB type-C cable, to read/write the chip, it needs no extra interface which otherwise increases costs.
