Patent number: 10808790Abstract: Apparatus and methods to reduce unwanted motion in a payload of a precision instrument are described. The payload may be supported by an intermediate mass. A feedback signal based upon sensed motion of the intermediate mass may be applied to an intermediate-mass actuator arranged to drive the intermediate mass. Additionally, a feedforward signal may be applied to a payload actuator arranged to drive the payload and used to suppress unwanted motion of the payload. The feedforward signal may be derived from a source within the apparatus or external to the apparatus that would otherwise cause unwanted motion of the payload.Type: GrantFiled: December 27, 2018Date of Patent: October 20, 2020Assignee: Technical Manufacturing CorporationInventors: Emil Kraner, Antonio Lopes, Justin Nealey

Publication number: 20190078643Abstract: Apparatus and methods to reduce unwanted motion in precision instruments are described. An active vibration-isolation system may be configured to receive a user-selectable setting, sense a stability of operation of the vibration-isolation system, and indicate whether the user-selectable setting provides stable vibration isolation. The settings may be changed by the user to improve vibration-isolation performance without requiring installation of the system by a skilled vibration-isolation engineer.Type: ApplicationFiled: March 15, 2017Publication date: March 14, 2019Applicant: Technical Manufacturing CorporationInventors: Emil Kraner, Steven T. RYAN, John E. BOOTH, Jeffrey L. WORTHEY

Patent number: 9353824Abstract: An active damping system for use in connection with a vibration isolation system includes an intermediate mass between a base and an isolated payload. The intermediate mass is supported by at least one support element which also supports at least substantially all of the static forces of the isolated payload. An actuator dampens and isolates dynamic forces acting on the intermediate mass from the isolated payload. The active damping system also includes a payload support element and a passive damping element, both of which are coupled at one end to the payload platform and at an opposite end to the intermediate mass. A sensor is affixed to the intermediate mass to generate a feedback signal to a processor coupled to the actuator.Type: GrantFiled: November 24, 2014Date of Patent: May 31, 2016Assignee: Technical Manufacturing CorporationInventors: Emil Kraner, Antonio Lopes

Patent number: 7726452Abstract: An active vibration damping system having a supporting spring for addressing a static force from a payload, and an independent actively isolated damper positioned in parallel between a payload and a source of vibration for damping dynamic force from the payload to an actively isolated point. The actively isolated damper includes a small intermediate mass, distinct and decoupled from the payload mass, and a passive isolator element for dynamic coupling of the isolated platform to the small intermediate mass. The small intermediate mass provides a point to which dynamic forces from the payload may be dampened. The active damper also includes at least one actuator coupled at one surface to the small intermediate mass and coupled at a second surface to the vibrating base platform. A motion sensor may also be provided on the small intermediate mass so as to generate a feedback signal as a function of the movement of the small intermediate mass.Type: GrantFiled: June 2, 2005Date of Patent: June 1, 2010Assignee: Technical Manufacturing CorporationInventor: Emil Kraner

Publication number: 20100030384Abstract: An active damping system for use in connection with a vibration isolation system is provided. The active damping system having an actuator for placement on the ground, and an intermediate mass supported on the actuator for acting as a stability point to which dynamic forces can be dampened and isolated from the payload. The active damping system also includes a passive damping element and a support spring, both coupled at one end to a payload and at an opposite end to the intermediate mass. At least one offload spring can be situated between the intermediate mass and the ground for partially supporting any weight from the payload acting on the actuator. A sensor can also be affixed to the intermediate mass to generate a feedback signal to the actuator for subsequent acting on the intermediate mass to permit the intermediate mass to act as a stability point. A system and method for isolating dynamic forces using such an active damper is also provided.Type: ApplicationFiled: July 29, 2008Publication date: February 4, 2010Inventors: Emil Kraner, Ulf Heide, Tony Lopes
