Abstract: In exemplary implementations, transplantation of nucleic acids into cells occurs in microfluidic chambers. The nucleic acids may be large nucleic acid molecules with more than 100 kbp. In some cases, the microfluidic chambers have only one orifice that opens to a flow channel. In some cases, flow through a microfluidic chamber temporarily ceases due to closing one or more valves. Transplantation occurs during a period in which the contents of the chambers are shielded from shear forces. Diffusion, centrifugation, suction from a vacuum channel, or dead-end loading may be used to move cells or buffers into the chambers.

Abstract: 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.

Abstract: 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.

Abstract: Cellular automotion digital material is useable for rapid prototyping and fabrication of continuous string conformations and two- or three-dimensional shapes through actuation of a string, surface, or volume composed of identical discrete units. Each unit is an actuated joint having a single degree of freedom. The actuated joint includes a two-part actuator having an inner active portion and an outer passive portion that are controllably rotatable relative to each other, the outer portion being configured to fit within the housing of an adjacent cellular automotion unit, and a linkage element that includes a main strut and a housing and is connected to the actuator by a pin connector. The housing is configured to house the actuator of an adjacent cellular automation unit, and the opening in the strut is rotated about the axis of symmetry of the cellular automotion unit relative to the opening in the housing so that the alignment of the cellular automotion unit will be rotated with respect to the alignment of any adjacent unit. The cellular automotion unit may include an on-board processor for controlling actuation of the cellular automotion unit.

Abstract: A family of reconfigurable, charge-conserving asynchronous logic elements that interact with their nearest neighbors permits design and implementation of circuits that are asynchronous at the bit level, rather than at the level of functional blocks. These elements pass information by means of charge packets (tokens), rather than voltages. Each cell is self-timed, and cells that are configured as interconnect perform at propagation delay speeds, so no hardware non-local connections are needed. An asynchronous logic element comprises a set of edges for asynchronous communication with at least one neighboring cell, each edge having an input for receiving tokens from neighboring cells and an output for transferring an output charge packet to at least one neighboring cell, and circuitry configured to perform a logic operation utilizing received charge packets as inputs and to produce an output charge packet reflecting the result of the logic operation.

Abstract: A digital assembler for creating three-dimensional objects from digital materials made out of discrete components comprises an assembly head, error correction mechanism, parts feeder, and a controller. The assembly head comprises several blades, each with a different function, that move in a linear direction as a unit, assembling the object line-by-line. One blade adds digital materials, another performs error recognition, another performs error removal, and another fills in new digital material where previously removed. In a method for building a structure out of digital materials, a new line is fed to the assembly head and added to the structure. Simultaneously, the new line is pressed down, the last line is checked for errors, the line before last is removed if errors were found during the last cycle, and the line second before last is replaced if it was removed during the previous cycle.
