Abstract:
Technologies are generally described for data protection in IoT devices through a compliance manager. A system for controlling and ensuring compliance of IoT devices data protection requirements may include IoT devices to perform various functions and a compliance manager in communication with the IoT devices and a network. The compliance manager, which may be implemented at a local hub or at the network, may categorize the IoT devices according to their functionality and enforce data protection policies for user privacy protection based on categories. An abstract data layer may store anonymized data from the IoT device before it is transmitted to the network. Users may be enabled to set/adjust policies based on categories. Information about compliance status of IoT devices may also be presented to the users.

The substrate (12) contains at least one vaporization heater (14), one or more bubble pumps (16) for feeding fluid from the fluid supply source (18) to the at least one vaporization heater (14), a fluid supply inlet from the fluid supply source (18) in fluid flow communication with each of the one or more bubble pumps (16), and a vapor outlet in vapor flow communication with the at least one vaporization heater (14). The one or more bubble pumps (16) each have a fluid flow path selected from a linear path, a spiral path, a circuitous path, and a combination thereof from the supply inlet to the at least one vaporization heater (14).

Abstract:
A printhead (10) including one or more fluid vias (110) in fluid communication with a fluid supply, each of the one or more fluid vias (110) being associated with a first number of heating elements, the heating elements being divided into groups of a second number of heating elements so as to form a number of primitive groups, and an electrical interface having at least one shift register that receives primitive address data to allow for selective application of electrical signals to the heating elements so that fluid is ejected from the printhead (10) in accordance with image data, the number of primitive groups being dependent on the print resolution of the printhead (10) so that a number of bits required for the at least one shift register to address each heater is independent of the print resolution of the printhead (10).
Abstract:
An inkjet printer (40) including a printhead (10) with a fluid ejection chip and an associated method of forming is described. The fluid ejection chip includes a substrate, a plurality of groups of drive elements formed on the substrate, and a plurality of fluid ejection devices disposed on the substrate. Each group of drive elements includes at least two drive elements electrically coupled in parallel. Each fluid ejection device of the plurality of fluid ejection devices is electrically coupled with a respective group of the plurality of groups of drive elements so that the plurality of drive elements selectively activate the plurality of fluid ejection devices for causing fluid to be expelled from the printhead (10) in accordance with image data.
Abstract:
A consumable supply item for an imaging device holds an initial or refillable volume of fresh fluid for use in an imaging device, A housing defines an interior having an expandable fluid receptacle to receive waste fluid from the imaging device. As the fresh fluid depletes in the interior over time, the fluid receptacle expands as it accommodates waste fluid. In this way, a single container can both 1) supply fresh fluid and 2) retrieve waste fluid. When full of fresh fluid initially, the fluid receptacle is empty in a compressed state. Upon fresh fluid leaving the container for the imaging device, waste fluid can begin filling the receptacle. Upon depletion of fresh fluid, the container is full of waste fluid. The container is ready for disposal or recycling.
Abstract:
A printer including an ink supply, a printhead cartridge, at least one fluid connection between the printhead cartridge and the ink supply, the printhead cartridge having a first configuration in which the fluid connection is coupled and the printhead cartridge is in electrical contact with other components of the printer and a second configuration in which the fluid connection is decoupled and the printhead cartridge is out of electrical contact with the other components of the printer, a cover latch having an open configuration and a closed configuration, and at least one moveable ejector arm that is mechanically linked to the cover latch so that the at least one ejector arm engages the printhead cartridge and forces the printhead cartridge towards the second configuration as the cover latch is moved towards the open configuration.
Abstract:
A consumable supply item for an imaging device holds an initial or refillabie volume of fluid. A housing defines an interior having a backpressure device that moves to regulate pressure in the housing as fluid exits the interior during use. A frame of the housing surrounds the interior and has a ledge. A first Sim seals to the ledge to prevent fluid from leaking, it is flexible to collapse inward toward the interior as the backpressure device moves inward. A second film seals to the housing over the first film and is spaced by air from the first film. The second film is relatively rigid. It is formed with metal. A tortuous air path traverses under the second film. It has an air inlet vented directly to atmosphere and an air outlet vented directly to the air space between the first and second films.
Abstract:
A pump for pumping fluid using peristaltic compression. The pump includes a rotor and a roller. The rotor includes a first cam that extends along a circumferential direction relative to the rotor. The first cam has first and second dwells. The roller is movable relative to the rotor between the first dwell and the second dwell of the first cam as the rotor rotates in a first direction and a second direction. The rotor includes a second cam extending radially from its shaft for engaging the roller. Contact between the second cam and the roller increases frictional resistance between the rotor and the roller as the roller translates between the first and second dwells of the first cam such that the roller transitions between the first and second dwells without slipping.
Abstract:
Technologies are generally described for providing real-time or recorded content along with customized content augmentation stream to enhance a user's experience of the content. A content provider may receive captured feedback from multiple users and select and aggregate a subset of the received feedback based on preferences and emotional state of a user to be presented with the content. The aggregated feedbacks may be customized for the user and delivered as content augmentation stream along with the content to the user.
