  • Patent number: 11879294
    Abstract: An actuating system includes a sleeve, a braking part for applying a braking force to prevent rotation of the sleeve, a brake releasing part, an axle coupler and an engaging part. The brake releasing part is operable to cause the braking part to release the braking force for rotation of the sleeve. The axle coupler is disposed through the sleeve, and is rotatable for raising and lowering a movable rail of a window shade. The engaging part is disposed between and can be in rolling contact with the axle coupler and the sleeve. The engaging part has a coupling position with respect to the axle coupler where the sleeve and the axle coupler are locked to each other in a first direction of rotation, and is movable away from the coupling position for rotation of the axle coupler relative to the sleeve in a second direction of rotation.

  • Patent number: 11767712
    Abstract: An actuating system includes an actuating wheel coupled to an operating element, an axle coupling part disposed substantially coaxial to the actuating wheel and rotatable for raising or lowering a bottom part of a window shade, and a clutching part carried with a carrier and movably linked to the actuating wheel. The clutching part is movable between a retracted state for disengaging from the axle coupling part and an extended state for engaging with the axle coupling part. The actuating wheel is rotatable in a first direction to urge the clutching part to move from the retracted state to the extended state and drive the carrier and the axle coupling part to rotate in unison, and in a second direction to urge the clutching part to move from the extended state to the retracted state so that the actuating wheel is rotationally decoupled from the axle coupling part.

  • Publication number: 20230291581
    Abstract: Arrangements and methods for a program-read-erase memory using ReRAM cells is disclosed. The memory includes an array of pristine ReRAM cells. A first digital symbol is encoded in the memory by partially forming cells, while the opposite digital value is encoded in pristine cells. As part of a read process, all cells are subject to partial formation voltage which erases all data as it is being read. ReRAM memories used in this manner are advantageously usable to store challenges for interrogating PUFs for recovery of PUF-generated encryption keys.
