Abstract: A shelf assembly may include a shelf top configured to support one or more stored articles (e.g. dumbbells, kettlebells, etc.), and at least one shelf bracket configured to be coupled to the shelf top and to a wall to securely position the shelf top relative to the wall. In some embodiments, the shelf bracket may be coupled to the wall in different ways so that in a first use position, the shelf top extends horizontally relative to the wall, and in a second use position, the shelf top is positioned in a downwardly sloped position relative to the wall. In further embodiments, the shelf bracket may be adjustable to enable the shelf top to be positioned over a range of desired positions.

Abstract: Techniques for processing packets on a network interface controller (NIC) with memory chiplets are disclosed. In an illustrative embodiment, a NIC includes a disaggregated memory with several high-bandwidth memory chiplets spread out in various locations on the NIC. The disaggregated nature of the memory can improve latency, throughput, and scalability as well as improve thermal performance by distributing heat generation to different locations on the NIC. In use, ports of the NIC can be configured to identify packets associated with certain flows and direct those packets to queues on the NIC. Direct memory access circuitry can copy the packets from queues on the NIC to queues on the system memory. This chain of copying packets from the port to the system memory creates a kind of virtual circuit, delivering packets directly to applications with low latency.

Abstract: A folding exercise rack system which may be both adjusted with respect to a wall and adjusted between a folded position for storage and an extended position for use. The folding exercise rack system generally includes an exercise rack that is both adjustable with respect to the wall and foldable between extended and retracted positions. The exercise rack generally includes a pair of inner support members which are adjustably connected to the wall, and a pair of outer support members which are adjustable between an extended position and a retracted (e.g., folded) position. In the extended position, the outer support members are distally spaced away from the inner support members and wall. In the retracted position, the outer support members are positioned adjacent to the wall.

Abstract: A carbonated water dispenser comprises a carbonator with a water inlet and a carbonated water outlet. A backflow preventer module is fluidically coupled to the water inlet and comprises a check valve and a thermal mass flow meter. The thermal mass flow meter is configured to communicate a first signal based on a measured amount of heat transferred from a heater to a temperature sensor by a flow of a fluid through the backflow preventer module. A shut-off valve is fluidically coupled between the carbonated water outlet and a nozzle. The shut-off valve is configured to allow or prevent fluid flow from the carbonated water outlet to the nozzle base on a control signal. A controller is configured to detect a backflow condition based on the first signal and generate the control signal to configure the shut-off valve to prevent dispensing carbonated water upon detection of the backflow condition.

Abstract: A flow control module with a thermal mass flow meter is provided. The thermal mass flow meter facilitates measuring both a flow rate and a temperature of a fluid passing through the flow control module. Fluids may experience different flow characteristics at different temperature ranges. The flow control module includes a proportional control valve for selectively adjusting the flow rate of the fluid passing through the flow control module. Upon detecting that the temperature of the fluid is outside of a temperature range for the fluid, a controller is configured to load a different set of calibration parameters for controlling the operation of the proportional control valve to accommodate the different flow characteristics of the fluid at that temperature. Additionally, the controller is configured to detect bubbles using the thermal mass flow meter based upon the difference in thermal conductivity of gasses and liquids.

Abstract: Various embodiments of the present disclosure relate to power conversion using a planar transformer assembly that provides medium-voltage isolation at high frequencies. A planar transformer comprises primary and secondary planar windings configured to generate an isolated output. Each primary and secondary winding is interleaved on layers of a printed circuit board using one or more vias within the layers of the printed circuit board. The planar transformer also comprises a magnetic core and a field-shaping apparatus coupled with the printed circuit board. The field-shaping apparatus is configured to shape an electric field generated by the windings. The primary windings can be coupled to a DC source via switching devices while the secondary windings can be coupled via switching devices to one or more DC ports followed by AC inverters configured to generate three single-phase AC outputs for medium voltage applications.

Abstract: A beverage making machine having a cartridge holder with an upper portion movable in pivotal and/or linear ways relative to a lower portion. An actuator for the cartridge portion may include a handle-actuated spur gear and link to move the upper portion, which may be guided in movement via a cam and cam follower engagement. Information from a cartridge detector may be used based on movement of cartridge holder portions, e.g., as an upper portion moves from an open position to a closed position. A mixing chamber may be held by a drawer so as to be removable, and movement of the drawer may engage/disengage the mixing chamber from a fluid supply.

Abstract: Systems, methods and cartridges for carbonating or otherwise dissolving gas in a precursor liquid, such as water, to form a beverage. Carbonating gas can be provided to a tank via the tank outlet, thereby purging at least a portion of a dispense line leading from the tank to a dispensing station. A single pump may be used to deliver liquid to the tank, e.g., for carbonation, and to pump pressurized air to dispense liquid from the tank. A water trap may help remove moisture from carbonating gas.
