  • Publication number: 20250251878
    Abstract: A quasi-volatile memory (QV memory) stack includes at least one semiconductor die, having formed thereon QV memory circuits, bonded to a second semiconductor on which a memory controller for the QV memory (“QV memory controller”) is formed. The circuits in the bonded semiconductor dies are electrically connected using numerous copper interconnect conductors and conductive through-silicon vias (TSVs). The QV memory controller may include one or more interfaces to additional devices (“back-channel devices”) to enable the QV memory controller to also serve as a controller for each back-channel device and to provide additional services. The QV memory controller performs data transfers between a back-channel device and the QV memory without intervention by the host CPU.

  • Patent number: 12376215
    Abstract: A lighting control system for controlling a cumulative light emitted by a lighting fixture may comprise a light-emitting diode (LED) driver comprising an output for conducting an output current, and a control module electrically coupled to the output of the LED driver for receiving the output current. The LED driver may regulate the magnitude of the output current towards a target current, and may be characterized by a low-end intensity. The control module may be coupled to a first LED light source of the LED light sources. The control module may receive a command including a requested intensity and control the magnitude of a first LED current through the first LED light source. The control module may control the cumulative light output of the lighting fixture below the low-end intensity of the LED driver by diverting a portion of the output current away from the first LED light source.

  • Patent number: 12364522
    Abstract: A method of preparing a metatarsophalangeal joint for fusion may involve surgically accessing the metatarsophalangeal joint and separating the metatarsal from the opposed proximal phalanx at the joint. The technique may involve preparing an end of the metatarsal and preparing an end of the opposed proximal phalanx for fusion. With or without the aid of a bone positioner, the metatarsal may be moved in one or more planes, such as the frontal and transverse planes. The proximal phalanx may also be moved in one or more planes, for example relative to the moved metatarsal. Subsequently, a bone fixation device can be applied across or through the metatarsophalangeal joint separating the metatarsal from the opposed proximal phalanx.
