Abstract: A LiDAR system includes an array of optical emitters, an objective lens optically coupling each optical emitter to a respective unique portion of a field of view, an optical switching network coupled between a laser and the array of optical emitters and a controller coupled to the optical switching network and configured to cause the optical switching network to route light from the laser to a sequence of the optical emitters according to a dynamically varying temporal pattern and to vary the temporal pattern in a way that reduces risk of eye injury from the laser light.

Abstract: A system and method of processing instructions may comprise an application processing domain (APD) and a metadata processing domain (MTD). The APD may comprise an application processor executing instructions and providing related information to the MTD. The MTD may comprise a tag processing unit (TPU) having a cache of policy-based rules enforced by the MTD. The TPU may determine, based on policies being enforced and metadata tags and operands associated with the instructions, that the instructions are allowed to execute (i.e., are valid). The TPU may write, if the instructions are valid, the metadata tags to a queue. The queue may (i) receive operation output information from the application processing domain, (ii) receive, from the TPU, the metadata tags, (iii) output, responsive to receiving the metadata tags, resulting information indicative of the operation output information and the metadata tags; and (iv) permit the resulting information to be written to memory.

Abstract: A device for treatment of cells with particles is disclosed. The device includes a semi-permeable membrane positioned between two plates, the first plate defining a first flow chamber and comprising a port, a flow channel, a transverse port, and a transverse flow channel, the first flow chamber constructed and arranged to deliver fluid in a transverse direction along the first side of the semi-permeable membrane, the second plate defining a second flow chamber and comprising a port. A method for transducing cells is disclosed. The method includes introducing a fluid with cells and viral particles into a flow chamber adjacent a semi-permeable membrane such that the cells and the viral particles are substantially evenly distributed on the semi-permeable membrane. The method also includes introducing a recovery fluid to suspend the cells and the viral particles, and separating the cells from the viral particles. A method of activating cells is disclosed.

Abstract: A multi-band/multi-polarization reflective or catadioptric optical system yields differing effective focal lengths (EFLs) per band/polarization. This approach could be used to create an imaging system, for example. In such case, a sensor (imager, spectrometer, diode, etc.) is located at the one or more focal planes. On the other hand, it could also be used to create a projecting system or hybrid projecting and imaging system by locating an emitter such as an LED, laser, etc.) at the image or focal plane. The system employs polarizers and/or dichroic coatings nano patterns to create different focal lengths and/or fields of view using the same mirrors and/or lenses by, for example, including at least one dichroic coating optically in front of at least one additional mirror to separately reflect the different bands or polarizations.

Abstract: A method for reconfiguring data referenced during the execution of a software system without the need for prior knowledge of a structured memory layout of the software system, may include parsing qualified software identifiers from the software system and categorizing the qualified software identifiers as either functions or variables, each associated with a name, data type, and data source, correlating the qualified software identifiers with at least one constraint defined by the categorizing, generating an order of execution of the qualified software identifiers based on the constraint, executing tasks defined by the software system according to the order of the qualified software identifiers, in response to a need arising during the execution of the software system, reconfiguring of the order of execution of the qualified software identifiers, and executing tasks defined by the reconfiguration of the order of the qualified software identifiers.

Abstract: A device, system and process involve conducting electroporation of microvesicles or exosomes or other target structures in a microfluidic arrangement at pressures that exceed atmospheric pressure. Single as well as multiple flow configurations can be employed. In some cases, the system and its operation are computer-controlled for partial or complete automation.

Abstract: A system and method of LIDAR imaging to overcome scattering effects pulses a scene with light pulse sequences from a light source. Reflected light from the scene is measured for each light pulse to form a sequence of time-resolved signals. Time-resolved contrast is calculated for each location in a scene. A three-dimensional map or image of the scene is created from the time-resolved contrasts. The three-dimensional map is then utilized to affect operation of a vehicle.

Abstract: Embodiments provide functionality to prevent collisions between robots and objects. An example embodiment detects a type and a location of an object based on a camera image of the object, where the image has a reference frame. Motion of the object is then predicted based on at least one of: the detected type of the object, the detected location of the object, and a model of object motion. To continue, a motion plan for the robot is generated that avoids having the robot collide with the object based on the predicted motion of the object and a transformation between the reference frame of the image and a reference frame of the robot. The robot can be controlled to move in accordance with the motion plan or a signal can be generated that controls the robot to operate in accordance with the motion plan.
