Patent number: 11648734Abstract: Provided is an additive manufacturing process that uses an upward-pointing illumination source, such as a laser, projected through a substrate so as to solidify particulate matter supported by the substrate. The process is then repeated to build a hanging part layer by layer, for example by replenishing particulate matter on the substrate, or by moving the part a second substrate that supports other particulate matter. The disclosed process eliminates the need for a large powder bed and also allows for sintering of different powders in a single layer so as to give rise to parts that include layers that are themselves made from multiple materials. Also provided are related methods, include methods of incorporated cured resins into parts made by fusing particulate matter.Type: GrantFiled: February 7, 2020Date of Patent: May 16, 2023Assignee: The Trustees of Columbia University in the City of New YorkInventors: John Whitehead, Hod Lipson

Patent number: 9959280Abstract: Systems and methods are provided herein for garbage collecting data previously tiered to cloud storage. A cloud object index can be generated and used to track objects stored in cloud storage. As objects within cloud storage are added or modified, the transactions can be tracked and the cloud object index can updated based on the activity. Expiration dates associated with cloud objects can be maintained in the cloud object index factoring in user defined retention periods, process defined retention periods for services like backup and snapshots, and regulatory defined retention periods depending on the type of data being tiered. Upon a determination that no active processes are linking to a cloud data object, that an expiration date has been met, and other custom factors, cloud objects can be removed from cloud storage permanently.Type: GrantFiled: September 30, 2014Date of Patent: May 1, 2018Assignee: EMC IP Holding Company LLCInventors: John Whitehead, Lijun Wang

Patent number: 9503542Abstract: Systems and methods are provided herein for writing back data to files tiered in cloud storage. Files tiered to cloud storage can be stored in chunks where each chunk is stored as a distinct cloud object and where each cloud object is mapped to known offset regions of a file and the mapping is stored in local storage within a stub file. If the file is modified locally, e.g., a write has occurred, the offset range associated with the write can be used to determine which cloud object associated with the file is being modified. A new cloud object can be stored with the write data, while the previous cloud object is retained in cloud storage. The mapping, stored within the stub file can updated to reference the new cloud object for the region of the file that was modified. In addition, mapping can be retained for the previous version of the file allowing for efficient recall of past versions of files.Type: GrantFiled: September 30, 2014Date of Patent: November 22, 2016Assignee: EMC CorporationInventors: Lijun Wang, Hualiang Xu, Bharat Sharma, Edward G.

Patent number: 8329268Abstract: A paper-based plant pot comprises a container formed from a sheet of paper-based material wrapped about an axis, opposite edge portions of the sheet being secured to each other, the container having a side wall that encircles the axis and a bottom wall formed by a plurality of bottom panels of the sheet folded inwardly from a lower edge of the side wall and engaging one another. The sheet comprises a paperboard substrate formed of natural cellulose fibers, an internal sizing composition incorporated into the paperboard substrate so as to render the paperboard substrate substantially resistant to saturation by liquid water, and a thermoplastic polymer layer on one of the major surfaces of the paperboard substrate. The thermoplastic polymer layer faces an interior of the container and forms an inner surface thereof for contact with soil or other growing medium placed in the container.Type: GrantFiled: December 7, 2009Date of Patent: December 11, 2012Assignee: Sonoco Development, Inc.Inventors: Susan Bell, Wim van De Camp, William David Decker, Bruce A.

Publication number: 20100129614Abstract: A low-density structural panel is made from used paper material such as shredded or divided old corrugated containers (OCC). The pieces of used paper material are mixed with an adhesive and the mixture is formed into a layer. The layer is compressed with a compression device to reduce its thickness and increase its density. The layer is heated to hasten the hardening of the adhesive. The process can be a batch process or a continuous process.Type: ApplicationFiled: May 8, 2008Publication date: May 27, 2010Applicant: SONOCO DEVELOPMENT, INC.Inventors: John Whitehead, Myles Cohen, Lawrence E.

Publication number: 20100106414Abstract: A method of performing routing in a global navigation satellite system (GNSS) navigation device incorporates user preferences determined through driving habits of the user. The GNSS navigation device stores a driving history, namely a plurality of route segments corresponding to maneuvers of a driver. The GNSS navigation device then determines which route segments of the plurality of route segments the user prefers based on the driving history. When generating a route, the GNSS navigation device then includes the preferred route segment.Type: ApplicationFiled: October 27, 2008Publication date: April 29, 2010Inventor: John Whitehead

Publication number: 20100062233Abstract: A method for reusing used paper material such as paperboard cartons comprises the steps of collecting used paper material after it has been used for its original purpose, dividing the used paper material into pieces without repulping the used paper material, coating an adhesive material onto the pieces, and assembling the coated pieces together into a layer to form a structural panel, the adhesive material binding the pieces together upon curing or drying. The pieces can be long narrow strips and/or shredded pieces and/or fiberized pieces that are essentially randomly oriented in the structural panel.Type: ApplicationFiled: March 7, 2008Publication date: March 11, 2010Inventors: Myles Cohen, Terry Gerhardt, Lawrence E.

Publication number: 20090022557Abstract: A tool including a drive shaft having an axis of rotation and a plurality of bit holders interchangeable with one another at a position of use. The bit holders are mounted at arcuately-spaced positions on a turret rotatable around an axis that is set at an angle to the axis of rotation of the drive shaft. The drive shaft is reciprocal between first and second axially-spaced locations at which, respectively, the drive shaft is engaged and disengaged from the bit holder at the position of use. The positioning of the drive shaft at the second location establishes a drive connection between the drive shaft and the turret so that subsequent operation of the drive shaft rotates the turret to interchange the positions of the bit holders at the position of use. The drive shaft is adapted to return to the first location and restore the drive connection with a new bit holder at the position of use after the turret has been rotated.Type: ApplicationFiled: April 11, 2006Publication date: January 22, 2009Applicant: Whitehot Solutions Pty LtdInventor: John Whitehead
