Abstract: A VPN tunnel interface is instantiated within a router based on a tunnel network namespace. One or more virtual peers corresponding to the VPN tunnel interface and one or more virtual ethernet interfaces corresponding to the one or more virtual peers are instantiated. The tunnel network namespace is configured to route, based on a source address, network traffic from a specified client device to a specified virtual peer of the one or more virtual peers via the VPN tunnel interface. A connection is established between a client device and a VPN process of the router and a traffic flow is transported to and from the client device through a VPN tunnel via the VPN tunnel interface, the one or more virtual peers, and the one or more virtual ethernet interfaces.

Abstract: Devices and methods for operating a diaphragm compressor system provide high output pressure and high throughput. In some embodiments, modular diaphragm compressors are stacked with a clamping mechanism pressing the compressor modules together. In embodiments, multiple stacks are provided as stages of a pressurization process. In embodiments, a main stage valve controls one or more pressure circuits for one or more hydraulic actuators of compressor modules. In embodiments, orifices configured for damping are incorporated to control actuator piston movement within a compressor module.

Abstract: A gutter broom is provided. The gutter broom can include a mandrel, one or more carriers, each carrier removably coupled to the mandrel, and one or more bristle strips, each bristle strip removably coupled to one of the carriers. The gutter broom components can be recyclable and modular, requiring no tools for assembly or servicing.

Abstract: Devices and methods for operating a diaphragm compressor. Embodiments of the present disclosure comprise an oil piston being driven to pressurize work oil against the diaphragm of the compressor. In embodiments, an injection pump provides a supplemental flow of work oil in the region of pressurized fluid, and such pump may be part of an actively controlled system. In embodiments, a pressure relief valve vents an overpump flow of work oil, and such valve may be variable. Embodiments provide feedback and control mechanisms, including control of the injection pump and the relief valve.

Abstract: Devices and methods for operating a diaphragm compressor system provide high output pressure and high throughput. In some force coupled embodiments, pressures on an actuator piston are balanced by high-pressure recovery or medium-pressure shuffling arrangements. In some embodiments, modular diaphragm compressors are stacked with a clamping mechanism pressing the compressor modules together. In embodiments, multiple stacks are provided as stages of a pressurization process. In embodiments, a main stage valve controls one or more pressure circuits for one or more hydraulic actuators of compressor modules.

Abstract: A two-step authentication system and method includes a location address and a non-visual identifier at the location address that is identified and verified via an electronic device. The electronic device may be a scan device at the location address that includes a unique identifier or may also be a GPS location at the address. The system uses one or more electronic devices to capture and verify the address for the delivery of a parcel along with the non-visual identifier assigned to the address location. Communication is provided to a user upon deliver.

Abstract: A hose repair system including a first clamping member and a second clamping member, each clamping member including an interior surface with a concave curve along the width and a pair of longitudinal grooves formed at the intersection of the first and second clamping members. Each longitudinal groove extends from end to end of each clamping member. The system also includes at least one fastener for clamping the first and second clamping members together.

Abstract: An oil extraction apparatus includes an ultrasonication vessel that receives raw plant material and ethanol. An ultrasonication probe ultrasonicates the raw plant material received in the ultrasonication vessel and generates a mixture including ultrasonicated raw plant material, plant oil, and ethanol. A collection vessel is in fluid communication with the ultrasonication vessel. The collection vessel receives a mixture including plant oil and ethanol from the ultrasonication vessel. A heater heats the collection vessel to separate ethanol from the mixture including plant oil and ethanol. A reclamation vessel is in fluid communication with the collection vessel. The reclamation vessel receives separated ethanol from the mixture including plant oil and ethanol. An ethanol collection tube is connected with the reclamation vessel. The ethanol collection tube is arranged to carry separated ethanol from the mixture including plant oil and ethanol to the reclamation vessel from the collection vessel.

Abstract: A gutter broom is provided. The gutter broom can include a mandrel, one or more carriers, each carrier removably coupled to the mandrel, and one or more bristle strips, each bristle strip removably coupled to one of the carriers. The gutter broom components can be recyclable and modular, requiring no tools for assembly or servicing.

Abstract: A gutter broom is provided. The gutter broom can include one or more block segments, each block segment having openings in which bristles are positioned. The bristles can have a first stiffness or a second stiffness different than the first stiffness. Bristles having the second stiffness can be positioned radially outward of bristles having the first stiffness on a block segment.
