摘要:
Apparatus and method for sensing the position, size, shape and location orientation of one or more objects in two dimensions. The position sensor uses arrays of light sensors mounted on a substrate. When an object passes in proximity to the light sensors light energy from a plurality of light sources is either reflected from the object to the light sensors, or is emitted directly to the light sensors. The light energy is then converted to individual signals and transmitted through circuit traces in a printed circuit board to a local controller. The information may then be processed to determine the size, position, shape and location orientation of an object.
摘要:
A distributed market based control assembly used in conjunction with fixed or movable structures. Typically multiple actuators are attached to the structure, with each of the multiple actuators having an actuator controller to control actuator applied force. Sensors are used for measuring structure movement, and a marketwire is connected to each actuator controller to convey price information to the actuator controllers by analog fluctuations in electrical characteristics of the marketwire. Actuators can be used to stabilize a fixed structure against movement, or alternatively can be used to control movement of movable structures from defined first positions to second positions (e.g. moving a robotic arm so its tip moves from point A to point B).

In a problem partitioning method for problem solving in a computer system, a definition of a system to be controlled, a hierarchical control structure definition, problem definitions for a plurality of control nodes in the hierarchical control structure, and a structure evaluation function are used in partitioning the system problem. The partitioning method defines an instantiation of the hierarchical control structure by decomposing the system into a plurality of hierarchical control structure instances, with each control structure instance having a plurality of control levels. The performance of each of the hierarchical control structure instances is evaluated with the structure evaluation function and an optimal hierarchical control structure instance is selected.

A method for problem solving in a computer system includes an applications module for sending a problem statement to a complexity module. The complexity module configures a solving module with configuration parameters and also determines expected solver behavior. A solving module determines actual solver behavior, determines whether a problem solution has been found, and determines whether to perform a solver iteration step or to request a complexity module to perform an adaptation step.
摘要:
A method and system allows for interactive, distributed job processing, e.g., print job processing, using a network, e.g., the Internet, and self-aware, remote processing equipment. Self-awareness allows the equipment to provide information about its load and status to a system controller such as a system server, either directly or through location servers located near the remote processing equipment. The method and system provide the capability to perform scheduling, routing and bidding on execution of jobs as well as re-routing, re-scheduling, remote proofing and remote processing instruction modification.

A method of marking employs a marking apparatus in which a propellant stream is passed through a channel and directed toward a substrate. Marking material, such as ink, toner, etc., is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. At sufficient velocity, and with appropriate marking material, the marking material may be kinetically fused to the substrate. A multiplicity of channels for directing the propellant and marking material allow for high throughput, high resolution marking. Multiple marking materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is single-pass, full-color printing.
摘要:
A valve for redirecting fluid flow has a valve chamber supporting fluid flow, with the valve chamber having an inlet, a first outlet, and a second outlet. The valve chamber can be closed or partially open. The flap element is movable to alternatively block the first outlet and the second outlet. In or immediately adjacent to the valve chamber are opposing first and a second catch mechanisms for controllably latching the flap element to block respectively the first outlet and the second outlet. The first and second catch mechanisms have a disabled state and an activated state for holding and allowing release of the flap element. Once the first or second catch mechanism is disabled, the flap element is free to move to another position, provided it can overcome the mechanical fluid flow forces that tend to hold it in position. To counter and utilize such forces for moving the flap element, an impulse mechanism kicks the flap element into the valve chamber, away from one of the first and second catch mechanisms, after one of the first and second catch mechanisms is controllably brought into the disabled state. Since the flap element is unstable, oscillations of the flap element in the fluid flow will eventually bring the flap element into catchment range of one of the first and second catch mechanisms in an activated state.
摘要:
A system for detecting and damping vibrations in printer components, mechanical devices, buildings, or large structures has a plurality of light beam detectors for generating signals corresponding to a reference light beam position. The light beam detectors are partially transparent to allow passage of the light beam through the detector, permitting multiple detectors to use the same reference light beam. The detectors are attached to vibration susceptible structural elements, with detected movement of the light beam with respect to the partially transparent light beam detector corresponding to movement of the vibration susceptible structural element. Motion control units connected to the detectors can be used to control or damp detected vibrations in real-time.
