Patent number: 11579041Abstract: According to some aspects, calibration techniques are provided that allow an optics module of an additive fabrication device to be installed and operated in a stereolithography device by a user. In particular, the calibration techniques enable the optics module to be calibrated in a way that only depends on the characteristics of the optics module, and not upon any other components of the stereolithography device. As a result, the techniques enable a user of a stereolithography device to remove one optics module and replace it with another, without it being necessary to repair or replace the whole device. In some cases, the calibration techniques may include directing light onto one or more fiducial targets within the stereolithography device and measuring light scattered from said targets.Type: GrantFiled: March 13, 2020Date of Patent: February 14, 2023Assignee: Formlabs, Inc.Inventors: Andrew M. Goldman, Henry Whitney, Justin Keenan, Benjamin FrantzDale, Michael Fogleman, Maxim Lobovsky

Patent number: 11390030Abstract: According to some aspects, techniques are provided to more accurately produce fine features in additive fabrication. According to some embodiments, the techniques comprise a process that amplifies exposure to edges and thin positive features whilst not substantially affecting negative features. In particular, an area to be cured may be adapted using signal processing techniques to produce an energy density map. The area may subsequently be cured according to the generated energy density map by, for example, adjusting the scan speed, light power and/or number of passes of the light beam according to the map. As a result, the net exposure to edges and thin positive features may be amplified.Type: GrantFiled: March 12, 2020Date of Patent: July 19, 2022Assignee: Formlabs, Inc.Inventors: Andrew M. Goldman, Henry Whitney, Justin Keenan, Benjamin FrantzDale, Michael Fogleman, Dmitri Megretski

Publication number: 20130168250Abstract: The present invention is directed to droplet actuator systems, devices, and methods. In one embodiment, a microfluidic article of manufacture is provided. The microfluidic article of manufacture includes a first substrate; a second substrate separated from the first substrate to form a droplet operations gap; gap height setting spacers associated with the first and/or second substrate or situated between the first and second substrates; a spring forcing the second substrate against the gap height setting spacers, thereby establishing a substantially uniform gap height between the first and second substrates; and electrodes associated with the first and/or second substrate and configured to conduct droplet operations in the droplet operations gap.Type: ApplicationFiled: September 15, 2011Publication date: July 4, 2013Applicant: ADVANCED LIQUID LOGIC INCInventors: Michael Fogleman, Ryan A. Sturmer, Gregory F. Smith

Patent number: 8364315Abstract: The present invention provides modified droplet actuator systems, software, and software-executed methods for use in droplet actuator operation and droplet actuator systems that are configured and programmed to execute such software. An aspect of the software components of the invention is an interface description file for each hardware component of a microfluidics system that allows hardware components to be changed without modifying the program for performing droplet operations protocols. Another aspect of the software components of the invention is the establishment of electrode-to-electrode relationships and other aspects of droplet actuator configurations, which may be used when programming droplet operations protocols. Another aspect of the software components of the invention is a physical design library of predefined electrode elements that may be used by a droplet actuator designer when constructing a layout of electrodes.Type: GrantFiled: August 13, 2009Date of Patent: January 29, 2013Assignee: Advanced Liquid Logic Inc.Inventors: Ryan A. Sturmer, Gregory F. Smith, Michael Fogleman, Keith R. Brafford, Sai Ram Rongali

Publication number: 20090203413Abstract: In general, in one aspect, a method for developing an asset by competition includes posting a list of competitions, each competition for the development of an asset, each element of the list including a reference to one of a number of workspaces, the one of the workspaces allocated to a respective asset. The method includes providing a draft competition specification in one of the workspaces. The method includes facilitating feedback from potential competitors on the draft competition specification in the workspace for a period of time prior to the competition. The method includes finalizing the draft competition specification based on the feedback from potential competitors, and holding a competition for the development of the asset.Type: ApplicationFiled: February 13, 2008Publication date: August 13, 2009Inventors: Anthony Jefts, Gregory Eldridge, Javier Fernandez-Ivern, Michael A.

Publication number: 20070088624Abstract: The invention relates to methods and systems for receiving, processing and fulfilling remotely placed orders. In one aspect, requests to place an order are received from a remote location, and based on a customer identifier included in the request, customer preference data is retrieved. An electronic selection menu based on customer preference data is transmitted to the customer, the order is received and prepared. The customer's arrival is automatically detected, and the completed order is provided to the customer.Type: ApplicationFiled: September 29, 2006Publication date: April 19, 2007Inventors: Drew Vaughn, Greg Hughes, John Hughes, Michael Fogleman
