Publication number: 20170368679Abstract: A robotic platform for traversing and manipulating a modular 3D lattice structure is described. The robot is designed specifically for its tasks within a structured environment, and is simplified in terms of its numbers of degrees of freedom (DOF). This allows for simpler controls and a reduction of mass and cost. Designing the robot relative to the environment in which it operates results in a specific type of robot called a “relative robot”. Depending on the task and environment, there can be a number of relative robots. This invention describes a bipedal robot which can locomote across a periodic lattice structure made of building block parts. The robot is able to handle, manipulate, and transport these blocks when there is more than one robot. Based on a general inchworm design, the robot has added functionality while retaining minimal complexity, and can perform numerous maneuvers for increased speed, reach, and placement.Type: ApplicationFiled: June 26, 2017Publication date: December 28, 2017Inventors: Benjamin Jenett, Kenneth Cheung, Neil Gershenfeld

Patent number: 9690286Abstract: A digital material skin is made of a set of discrete units with a finite set of parts and joints. The discrete units are assembled into a layer according to a regular geometry, with each of the discrete units being reversibly connected to at least one other unit in the set. The reversibly connected set of units forms an exterior structure surface that is larger than the individual discrete units. Digital material skins may be used to construct any shape or interior volume, whether regular or amorphous. The skin surface may be enclosed or open. The skin may rely on an interior digital material structure for support or may be self-supported. The skin may be part of a larger assembly or apparatus, enclosing an interior volume or structure.Type: GrantFiled: June 21, 2013Date of Patent: June 27, 2017Assignee: Massachusetts Institute of TechnologyInventors: Sarah Hovsepian, Neil Adam Gershenfeld, Kenneth Cheung

Patent number: 9462354Abstract: Techniques and systems for operating a video ad exchange includes controlling an ad server to receive ad requests from viewer devices, provide ad responses to viewer devices, generate an ad delivery data file that includes information about delivery of ads to the viewer devices, and transfer the ad delivery data file to a distributed computing cloud. The technique further includes controlling an ad data infrastructure mechanism to download the cloud-based ad delivery data file into a local memory, and process the copied ad delivery data file to generate billing data. An ad data infrastructure mechanism receives a configuration file from the ad server, verifies that all items in the configuration file from the ad server were used in the generation of the first billing data, and removes non-verifiable items from the first billing data to generate a final billing data.Type: GrantFiled: March 14, 2014Date of Patent: October 4, 2016Assignee: Yahoo! Inc.Inventors: Giao Huu Phan, Daniel Wei-Tze Hsiung, Ian Graeme Melven, Brian Hardie, Joseph Gutierrez, Marshall Allen Beddoe, Pankaj Gupta, Bernardo de Seabra, Dru Nelson, Kam Ho Kenneth Cheung, Jason Endo

Patent number: 9073962Abstract: In exemplary implementations of this invention, hierarchical, nanometer-precise assembly is performed: A first structural unit is attached to a solid substrate in a first fluidic flow. A second structural unit is attached to the first structural unit in a second fluidic flow, a third structural unit is attached to the second structural unit in a third fluidic flow, and so on, until a target structure comprising the structural units is assembled. The first, second, third and so on fluidic flows are separate and occur in order in a temporal sequence. During the temporal sequence, a specific permutation of nucleobases is used repeatedly, in separate fluidic flows which occur at different times, to form multiple attachments between structural units in an assembly. The assembled target structure is removed from the solid substrate. Attachments between the structural units may be formed by nucleobase pairing.Type: GrantFiled: July 12, 2013Date of Patent: July 7, 2015Assignee: Massachusetts Institute of TechnologyInventors: Charles Fracchia, Neil Gershenfeld, Kenneth Cheung

Patent number: 8986809Abstract: In exemplary implementations of this invention, a digital material comprising many discrete units is used to fabricate a sparse structure. The units are reversibly joined by elastic connections. Each unit comprises fiber-reinforced composite material. Each unit is small compared to the sparse structure as a whole. Likewise, in a sparse structure made from this digital material, the number of types of units is small compared to the total number of units. The digital material is anisotropic. This anisotropy may be due to different fiber orientations within each unit. Furthermore, different units in a single sparse structure may be oriented in different directions and in different, non-parallel planes. In some cases, the digital material is reinforced with carbon fibers, and connections between units are stronger than the units themselves. The small discrete units may be assembled into a strong, lightweight sparse structure, such as an airframe.Type: GrantFiled: October 19, 2011Date of Patent: March 24, 2015Assignee: Massachusetts Institute of TechnologyInventors: Neil Gershenfeld, Kenneth Cheung

Patent number: 8879432Abstract: Complementary band-splitter and band-combiner devices and methods of operation of both are disclosed. Embodiments of the invention may allow wideband and narrowband functions and services to operate seamlessly by band-splitting wideband data into low-band data and high-band data. Narrowband data may include only low-band data. Wideband services may operate on both low-band and high-band data, while narrowband services may operate only on low-band data. Another embodiment may include computer-readable storage having stored thereon a computer program having a plurality of code sections executable by a processor for causing the processor to perform the foregoing.Type: GrantFiled: December 6, 2002Date of Patent: November 4, 2014Assignee: Broadcom CorporationInventors: Wilf LeBlanc, Phil Houghton, Kenneth Cheung

Patent number: 8473093Abstract: In exemplary implementations of this invention, a network of nodes controls and senses the cure of a thermosetting plastic in a component that is made of fiber composite material. The network comprises multiple nodes, which are separated spatially from each other. Each of the nodes, respectively, comprises a heat transfer device for actively transferring thermal energy, a temperature sensor for taking local temperature measurements, and a processor. In each of the nodes, respectively: (a) the processor locally performs closed loop control over the temperature of the heat transfer device, and (b) the closed loop control is based at least in part on the local temperature measurements and on estimated or measured input current to the heat transfer device.Type: GrantFiled: February 2, 2012Date of Patent: June 25, 2013Assignee: Massachusetts Institute of TechnologyInventors: Neil Gershenfeld, Nadya Peek, Kenneth Cheung, David Watson
