Abstract: Disclosed herein are various bioreactor devices and systems for growing cellular material, and related methods of growing cellular material. In some cases, a system can include a well plate having a plurality of wells and a bioreactor situated in each well of the well plate. In some cases, a bioreactor can include an inner body which divides the bioreactor into several distinct chambers and facilitates the growth of a multi-tissue sample in the bioreactor. In some cases, a system can include a mechanical actuator situated to mechanically stress tissues grown in a bioreactor.

Abstract: A hydrogen fueled powerplant including an internal combustion engine that drives a motor-generator, and has a two-stage turbocharger, for an aircraft. A control system controls the operation of the motor-generator to maintain the engine at a speed selected based on controlling the engine equivalence ratio. The control system controls an afterburner, an intercooler and an aftercooler to maximize powerplant efficiency. The afterburner also adds power to the turbochargers during high-altitude restarts. The turbochargers also include motor-generators that extract excess power from the exhaust.

Abstract: A robotic vehicle is provided with an extendable arm and a mandible structure. The mandible structure includes a pair of mandibles with toothed portions that cooperatively engage such that the mandibles may be opened and closed by applying a force to only one of the pair of mandibles. The mandible structure hangs freely from the extendable arm and is balanced so that the mandible structure naturally maintains a substantially vertical orientation. In the closed position, the mandible structure defines an interior cavity suitable for securely grasping a ring.

Abstract: A method of preparing a smokable cannabis-based product with reduced psychoactive effects and method for producing the same, comprising the steps of: (a) separating portions with known low tetrahydrocannabinol content from harvested plant material of the cannabis; (b) separating plant matter which has previously been used in a cannabis oil extraction process; (c) combining specific amounts of the separated materials to produce a cannabis plant material mixture possessing a specific active cannabis compound profile using a mixing device; and (d) loading the mixture of cannabis plant material into the cylindrical smokable tube using a loading device.

Abstract: A class of medically-effective formulations comprising cannabinoids, and terpenes, using ?-myrcene to improve effectiveness. B-myrcene decreases resistance across the blood-brain barrier for both itself and a plurality of other medically-active compounds such as other terpenes, cannabinoids, and flavonoids. Further, ?-myrcene has been determined to raise the saturation level of the cannabinoid receptor CB1 for phytocannabinoids such as delta(9)-tetrahydrocannabinol, and to increase cell membrane permeability for itself as well as cannabinoids, terpenes, flavonoids and other naturally occurring cannabis compounds, thereby improving therapeutic benefits of cannbis formulations.

Abstract: Described herein is an end-to-end solution (i.e., capable of constructing a content delivery network all the way from an origin server to end user devices) which provides a managerial overview to what has been a very disjoint build-out of networks. In the past, networks have evolved to serve particular needs, as opposed to being architected from a strategic view. What this does is to allow someone (e.g., content provider, network operator, etc.) to impose a strategy over those networks. Rather than having to construct solutions that deliver a particular kind of content, a particular security requirement, a particular latency requirement, etc., one can simply provision particular types of nodes as needed when needed.

Abstract: Methods and devices are described for generating a recipe for creating a clip. A clip request may be received at a server, such as a content server. The clip request may be related to a clip including audio and/or video. The server may include one or more processors and a cache, the cache including chunks. Each chunk may store a predetermined positive number of bytes of data. The server may search the cache to determine whether the clip is to be generated from a recipe stored within the cache. The recipe may include one or more tasks. The server may generate the clip in view of the one or more tasks of the recipe. The server may transmit a clip response comprising the clip to the client device.

Abstract: A robotic vehicle is provided with vertical ball cannon and a ball deflector. The ball deflector is mounted over the vertical ball cannon on a vertical linear slide. The deflector redirects a ball shot from the cannon toward a desired target, such as a cylindrical goal. The vehicle further includes a rotating goal-grabber for anchoring a goal adjacent to the vehicle and underneath the output of the deflector. A pair of counter-rotating helical screws capture a ball from the ground and raise it into the ball cannon. The cannon launches the ball toward the deflector, which redirects the ball's upward vertical motion away from the cannon into a downward vertical motion toward the desired target.

Abstract: A hydrogen storage tank for a hydrogen fueled aircraft. The tank has a wall made of layers of aerogel sections around a hard shell layer, sealed within a flexible outer layer, and having the air removed to form a vacuum. The periphery of each layer section abuts other sections of that layer, but only overlies the periphery of the sections of other layers at individual points. The wall is characterized by a thermal conductivity that is lower near its gravitational top than its gravitational bottom. The tank has two exit passageways, one being direct, and the other passing through a vapor shield that extends through the wall between two layers of aerogel. A control system controls the relative flow through the two passages to regulate the boil-off rate of the tank.

Abstract: A system is described to enable charging of electric vehicles. A scheduler determines charging profiles for electric vehicles based on a time period within a day that is beneficial to an electric grid while still meeting the needs of drivers of the electric vehicles. A service provider charges the electric vehicles according to the charging profiles.

Abstract: Methods and devices are described for generating a recipe for creating a clip. A recipe request can be received at a server, such as a recipe server. The recipe request may be related to a clip including audio and/or video. The server can generate a recipe for creating the clip using one or more slices of a data source. The recipe can include one or more tasks that can include a data-source task which can include a specification of the data source and slice definitions for the one or more slices. The data source can include a video and/or audio data source. A slice definition can include a slice value and a slice offset for locating a respective slice within the data source. The recipe can then be transmitted from the server.

Abstract: A method of driving an isolated converter includes opening a first bi-directional switch on an input side of a transformer, accepting current into a resonant capacitor connected across the first bi-directional switch to reduce voltage across the first bi-directional switch in response to said opening the first bi-directional switch, reversing current out of the resonant capacitor, and closing the first bi-directional switch as voltage across the first bi-directional switch is approximately zero volts.
