  • Publication number: 20250047799
    Abstract: An imaging system comprising an imaging device and a supply item installed in the imaging device. The imaging device comprises: a system control component having host firmware stored thereon, the system control component comprising a print head operation module actuatable by the host firmware to transmit signals to a print head of the imaging system, the signals configured to cause the print head to operate. The imaging device further comprises: an imaging device security device and a monitor-enforce module. The monitor-enforce module comprises: a monitor interface configured to receive security information from the imaging device security device, wherein the security information indicates an authentication status of the supply item, and an enforce module, the enforce module being configured to selectively interrupt said signals transmitted by the print head operation module, based on the security information.

  • Publication number: 20250030809
    Abstract: A supply item has toner for use in an imaging device. A chip has memory storing quanta indicating allowed usage of the supply item over its lifetime and a multiplier correlating the quanta to toner mass. The imaging device requires quanta to conduct imaging operations and loads the quanta and multiplier by way of a certificate stored in the memory. The imaging device retrieves quanta from the chip over time and both devices keep tally. Initialization between the supply item and imaging device includes providing encrypted and unencrypted instances of firmware versions and certificates from the supply item that the imaging device can compare for security. Alternatively, the supply item defines a fuser assembly, imaging unit, intermediate transfer member, or other component installed for use in the imaging device.

  • Patent number: 11730498
    Abstract: An aspiration system comprises an aspiration catheter, an aspiration source fluidly coupled to the aspiration catheter to create an aspiration flow path between the aspiration catheter and the aspiration source, a pressurized fluid source, and a passive pressure oscillation assembly fluidly coupled between the pressurized fluid source and the aspiration flow path. The passive pressure oscillation assembly is configured for being operated between a normal mode that prevents fluid communication between the pressurized fluid source and the aspiration flow path, and an oscillatory mode that pulses fluid communication between the pressurized fluid source and the aspiration flow path. The passive pressure oscillation assembly is configured for being triggered to switch from the normal mode to the oscillatory mode in response to a clog in the aspiration catheter.
