  • Publication number: 20230189446
    Abstract: A method for mounting a component (100) on a workpiece (106), the method comprising obtaining information regarding a surface topography of at least one of a mounting surface (102) of the component and a local surface (108) of the workpiece onto which the component is to be mounted. The method further comprises forming a plurality of deposits (110) of a viscous medium on at least one of the mounting and local surfaces, wherein each of the plurality of deposits has a height (/½, /½, h3) based on the obtained information, and is formed by individually applying at least one droplet (234) of the viscous medium (232) using non-contact dispensing. The method further comprises placing the component on the substrate, such that the plurality of deposits of viscous medium forms a connection between the component and the workpiece.

  • Patent number: 11007101
    Abstract: A motive system for a patient lifting assembly, a patient lifting assembly and a method of operating a patient lifting assembly. The motive system includes an electric motor, numerous sensors and an adaptive control unit cooperative with one another so that a memory and processor that are part of the control unit that can respectively store and execute a computer readable and executable instruction set. By comparing collected data from the sensors during operation of the motor to corresponding reference values associated with one or more motor operational parameters—such as accumulated motor wear over time or differences in operating temperature of the motor—the system can selectively adjust the maximum amount of current available for use by the motor. In this way, changes in motor efficiencies that arise with these parametric changes can be taken into consideration when determining an upper limit on how much electrical current may be delivered to the motor for a given load.

  • Patent number: 9341962
    Abstract: In a method for patterning a workpiece provided with dies in a direct write machine, pattern data associated with a selected die, or group of dies, is transformed into adjusted circuit pattern data dependent both on the original pattern data and the transformed positions, wherein the adjusted circuit pattern data represents the circuit pattern of the plurality of dies, or group of dies, such that the adjusted circuit pattern is fitted to a plurality of sub-areas of the workpiece area, and wherein each sub-area is associated with a die, or group of dies, among the plurality of dies distributed on the workpiece. A pattern is then written on the workpiece according to the adjusted circuit pattern data.

  • Patent number: 8594824
    Abstract: A method for patterning a workpiece in a direct write machine in the manufacturing of a multilayer stack, wherein a first circuit pattern comprising patterns for connection points is transformed according to determined fitting tolerances to fit to connection points of a second circuit pattern and to circuit pattern(s) of specific features such as random placed dies, or group of dies, on or in the workpiece. The second layer may be a previously formed layer or a layer to be formed on the same workpiece or on a different workpiece for the stack. Pattern data associated with selected die is transformed into adjusted circuit pattern data using the transformation defined by the transformed positions such that the circuit pattern is fitted to the selected die(s).

  • Patent number: 8530120
    Abstract: A method for patterning a second layer of a work piece in a direct write machine in the manufacturing of a multilayer system-in-package stack. The work piece having a first layer with a plurality of electrical components in the form of dies arbitrarily placed. Each component having connection points where some need to be connected between the components. A first pattern wherein different zones comprising connection points of dies distributed in the first layer are associated with different requirements on alignment. The method comprising the steps of: a. Detecting sacred zones in first pattern that have a high requirement on alignment to selected features of the system-in-package stack or to the placed components; b. Detecting stretch zones of the first pattern that are allowed to have a lower requirement on alignment to other features of the system-in-package stack; c.
