Abstract: The present disclosure provides autonomous vehicle systems and methods that include or otherwise leverage a motion planning system that generates constraints as part of determining a motion plan for an autonomous vehicle (AV). In particular, a scenario generator within a motion planning system can generate constraints based on where objects of interest are predicted to be relative to an autonomous vehicle. A constraint solver can identify navigation decisions for each of the constraints that provide a consistent solution across all constraints. The solution provided by the constraint solver can be in the form of a trajectory path determined relative to constraint areas for all objects of interest. The trajectory path represents a set of navigation decisions such that a navigation decision relative to one constraint doesn't sacrifice an ability to satisfy a different navigation decision relative to one or more other constraints.

Abstract: A method for tracking an item in a distributed environment is provided. At least one node in a network adds a new block to a first cryptographically verifiable ledger represented by a first sequence of blocks that is stored in one or more non-transitory computer-readable media. The new block added to the first cryptographically verifiable ledger contains a component identifier and a hash of a previous block in the first sequence of blocks. The at least one node in the network adds a new block to a second cryptographically verifiable ledger represented by a second sequence of blocks that is stored in the one or more non-transitory computer-readable media. The new block added to the second cryptographically verifiable ledger contains a destination identifier, the first sequence of blocks, and a hash of a previous block in the second sequence of blocks.

Abstract: Each of the processing devices stores an event vector, which is updated when certain events (e.g. memory errors, overtemperature events) occur on the device. Different elements of the vector correspond to different types of events. When an event of a given type occurs on one device, the update to the event vector on that device is propagated to other devices in the system. Those other devices, in response, update the corresponding element in their own event vector to indicate that an event of that given type has occurred in the system. In this way, events are aggregated between the different devices using the event vector. The event vector is considered to be a global event vector, since its elements indicate whether certain events have occurred across the entire system, and the vector is consistent across the system.

Abstract: A computer system (110) for controlling a thermoset printer (100) to create desired material attributes comprises one or more processors (210) and one or more computer-readable media (220) having stored thereon executable instructions that when executed by the one or more processors configure the computer system to perform various acts. The computer system may receive an indication of one or more thermoset materials that are to be used by the thermoset printer (100) to print a target object (120). The computer system (110) may also access a material attribute dataset that describes different material properties of the one or more thermoset materials during printing. Based upon the material attribute dataset, the computer system determines a particular extrusion configuration for the one or more thermoset materials and generates a command to cause the thermoset printer to implement the particular extrusion configuration while printing the target object (120).

Abstract: Systems and methods for radio-frequency identification (RFID) are disclosed where session control tasks are offloaded from a plurality of zoned RFID readers to a separate device which can take the form of an RFID transmitter such as a session control broadcaster. Accordingly, the RFID transmitter transmits messages to RFID tags to control which of the RFID tags within range of the RFID transmitter are in a readable state and/or unreadable state. These messages can take the form of session control messages. By offloading the transmission of messages that control the readability of RFID tags to a separate RFID transmitter, the RFID system frees up the zoned RFID readers to spend more time on inventory read operations, which reduces the risk that an RFID tag will stay hidden when it briefly exists in a hot spot.

Abstract: A shieldable needle device with a needle cannula, a hub supporting the needle cannula, and a tip guard axially movable along the needle cannula where, upon transition, the tip guard protectively surrounds the distal end of the needle cannula. The needle device includes a pair of wings extending laterally from opposing sides of the tip guard and connected to the hub. The pair of wings are transitionable between a first position and a second position, wherein transition of the pair of wings advances the tip guard from a proximal position to a shielding distal position. The wings include protrusions which cause the longitudinal axis of the needle cannula to become offset from the opening of the tip guard during advancement of the tip guard preventing the needle cannula from being reinserted through the tip guard after the tip guard has been transitioned to the distal position.

Abstract: Disclosed herein is a dental device for delivering fluid continuously while activated in an endodontic application. The dental device includes a hollow needle having a tip end and a connector portion; and a handle. One end of the handle is configured to be affixed to the connector portion of the hollow needle. The opposite end of the handle is capable of being attached to an endodontic handpiece or a sonic agitator for the activation. The connector portion includes at least one tube connector that is an integral part of the connector portion of the hollow needle or a plurality of openings on the connector portion to accommodate the hollow needle to a connector. The connector is a modular fluid delivery connector which is removable from the needle such that it can be reused.

Accordingly, the RFID transmitter transmits messages to RFID tags to control which of the tags within range of the RFID transmitter are in a readable state and/or unreadable state.
