Abstract: Systems and methods of the present disclosure include at least one building component detection sensor device configured to be deployed within (or proximate to) a building comprised of a plurality of building components. The at least one building component detection sensor device is configured to detect data relating to at least one building component of the plurality of building components. In addition, a building component property determination system includes a processor configured to execute instructions stored in memory to determine one or more properties of the at least one building component based at least in part on the data detected by the at least one building component detection sensor device.

Abstract: Components for valve treatment systems are disclosed. Valve treatment systems can include a delivery system for an implantable device. The delivery system can include one or more of clasp control components slidably disposed on a catheter handle, a control element for opening and closing the implantable device, a catheter assembly with features to reduce friction with another catheter assembly, grips for attaching catheter assemblies to clamps, catheter assemblies with features that stiffen or provide variable stiffness, and catheter assemblies with one or more steering control lumens incorporated into a reinforcement layer.

Abstract: In an imaging device having a photoconductive drum and a lubricant applicator brush, methods and apparatus teach application of the lubricant to the drum at a transfer nip and removing undeveloped toner particles. A first voltage is applied to the drum while the brush receives a voltage that switches more positive and more negative than the first voltage. It attracts to the brush from the drum negatively and positively charged toner. Embodiments contemplate amounts of voltages and frequencies of switching. An elongate rod contacts the brush downstream of the transfer nip to flicker off the toner particles from the brush. The rod can also have voltages applied and switched greater than and lesser than the voltages of the applicator brush to facilitate toner removal. A cleaning blade downstream of the transfer nip scrapes clean a surface of the drum.

Abstract: Disclosed is a printhead for a printer that includes a plurality of ejection chip units. Each ejection chip unit of the plurality of ejection chip units is configured to eject at least one fluid. The printhead further includes a plurality of supporting units. Each supporting unit of the plurality of supporting units is fluidly coupled with a corresponding ejection chip unit. The each supporting unit includes a plurality of trenches adapted to receive an adhesive to facilitate attachment of the each supporting unit with the corresponding ejection chip unit. Furthermore, the printhead includes a base unit fluidly coupled with the each supporting unit of the plurality of supporting units. The base unit is adapted to provide the at least one fluid to the each ejection chip unit through a corresponding to supporting unit. Further disclosed is a method for assembling the printhead.

Abstract: A modular micro-fluid ejection device includes a carrier frame supporting pluralities of micro-fluid ejection modules. Each of the modules has a plate of nozzles defining a plane. Adjacent nozzle plates are substantially coplanar and registered with one another across the entirety of the carrier frame. Methods to mount the modules to the frame include, first, temporarily mounting one module and then another, and then permanently mounting both with a durable adhesive. Manufacturing systems include suction devices to hold a first module in place on a fixture while later modules are suctioned and registered to each other. Once set in place, a carrier frame is commonly contacted to the modules and the suction to released. Adhesives between the frame and modules cause the modules to separate from the fixture and transfer to the frame. All remain properly registered upon transfer.

Abstract: A fluid printing process such as one that includes subdividing a desired printed pattern into geometrical elements and thereafter sequentially printing these elements in a series of subsets by depositing one or more fluid formulations onto a substrate, and subsequently exposing the deposited fluids to energy in order to dry the deposited one or more fluids substantially and immediately upon deposition so as to control at least one of solid deposition and surface roughness.

Abstract: Droplet deposition apparatus comprises an array of fluid chambers, each chamber communicating with an orifice for droplet ejection, a common fluid inlet manifold and a common fluid outlet manifold, and means for generating a fluid flow into the inlet manifold, through each chamber in the array and into the outlet manifold, the fluid flow through each chamber being sufficient to prevent foreign bodies in the fluid from lodging in the orifice. Each chamber is associated with means for effecting droplet ejection from the orifice simultaneously with the fluid flow through the chamber. The resistance to flow of one of the inlet and outlet manifolds is chosen such that the pressure at a fluid inlet to any chamber in the array varies between any two chambers by an amount less than that which would give rise to significant differences in droplet ejection properties between these two chambers.

Abstract: A vacuum drum assembly for a printing machine has a drum with an array of passageways distributed along its length and around its periphery. The passageways permit air to flow from outside the drum to inside the drum in response to reduced air pressure inside the drum. The assembly also has an array of valve members, each valve member being movable between a closed position in which that valve member restricts at least one of the passageways and an open position in which the restriction of that passageway or those passageways is reduced. The assembly is arranged such that, when a partial area of the drum is wrapped with a sheet of material, at least some of the valves for the passageways adjacent the edges of that area are open, and the valves for the passageways which are not covered by the sheet and are not adjacent the edges of that area are closed.

An array of valves are movable between a closed position in which that valve restricts at least one of the passageways and an open position in which the restriction of the same passageways is reduced. When a partial area of the drum is wrapped with a sheet of material, at least some of the passageway valves adjacent the edges of that area are open, and the valves for the passageways not covered by the sheet and not adjacent the edges of that area are closed. The drum open area is regulated to be small in regions where there is no paper. Accordingly, the open area of the drum is adapted to the paper shape and size and the paper position on the drum, while minimizing the required suction flow.
