Abstract: A container includes container body (120) defining an interior (122) and an opening (124) leading to the interior. A lid (140) is movable with respect to the container body to move the container between a closed position in which the lid covers the opening and an opened position in which the opening is exposed. A housing (180) is affixed to an upper portion of the container body, adjacent to the opening. A release (160) is movably housed within the housing. The release is configured to move between a locked position in which the release retains the lid in the closed position, and an unlocked position, in which the release permits the lid to move into the opened position. The release moves from the locked position to the unlocked position by a first movement in a radially inward direction of the container, followed by a second movement in an axially upward direction of the container.

Abstract: Improvements in the supply of high-frequency electrical power to ozone-producing cells can be accomplished using the systems and techniques described herein. Application of a DC-DC converter operating at a switching frequency substantially greater than a load frequency, supports generation of a high-voltage AC for powering such cells, while allowing for reductions in component size and reductions in a quality factor of a load tuning circuit. Controllable power inverters used in obtaining one or more of the switching and load frequencies can be controlled using feedback techniques to provide stable, high-quality power to ozone-producing cells under variations in one or more of externally supplied power and load conditions. An inrush protection circuit can also be provided to selectively introduce a current-limiting resistance until an input DC bus has been sufficiently initialized as determined by measurements obtained from the DC bus.

Abstract: Containers with closures are disclosed. A closure may include at least a polymer orifice reducer configured to be permanently secured to a rim of an opening of a container and a flexible tamper evident seal disposed on the topside of the orifice reducer. The flexible tamper evident seal, optionally foil, covers one or more openings in the orifice reducer. Processes for permanently securing a closure to a container, optionally by forming a heat seal between the orifice reducer and container rim, are also disclosed.

Abstract: Methods for storing and preserving cannabis or cannabis-containing substances using container assemblies are disclosed. An exemplary container assembly includes a lid and a container body. The lid is configured to be closed onto the container body over an opening of the container body. The opening provides access to an interior space having a product compartment configured to store product. The assembly also includes a humectant compartment permanently secured within the assembly. The humectant compartment includes a rigid housing containing a humectant solution. The rigid housing is configured within the assembly to prevent leaking of the humectant solution into the product compartment while facilitating bidirectional transmission of moisture between the humectant compartment and the product compartment. The humectant solution regulates relative humidity of the product compartment to maintain the relative humidity at a predetermined level.

Abstract: A container assembly for storing one or more arrays of flat elongate articles is provided. The assembly includes a container body having a base, a sidewall extending vertically from the base, a dispensing opening and an interior space. The container further includes a lid optionally linked to the container body by a hinge. The lid is configured to seat on the container body and cover the dispensing opening when the lid is closed. The assembly further includes an insert disposed within the interior space of the container body. The insert is adapted to hold at least one array of flat elongate articles in a generally vertical and optionally slightly slanted storage position. The insert includes a platform adapted to hold a first flat elongate article in an array higher than an adjacent second flat elongate article in the same array.

Abstract: A system and method for determining, via ultrasound, a size of a concretion in a subject are provided. One or more ultrasound pulses are transmitted into a tissue in the subject, which are then reflected from the tissue and received by the ultrasound transducer. A shadow region obscured by the concretion that does not provide reflected signals is generated, and the width of the shadow region is measured. The width of the object is determined based on the width of the shadow region.

Abstract: A power system for a dielectric barrier discharge system, such as used for generating ozone, can include a full bridge inverter stage and parallel resonant tank outputting a signal for powering a dielectric barrier discharge cell stack. The inverter stage is controlled using a combination of pulse width modulation (PWM) and frequency modulation (FM) to enable soft switching through all load conditions—from full load to light load. A current control loop error amplifier compensator can provide a duty cycle adjustment signal to a phase shift PWM controller chip that generates the switching signals for the inverter stage. A feedback signal is also used to adjust a clock frequency time constant of the PWM controller chip to provide the FM. In one embodiment, the feedback signal is an output of an inverting amplifier connected at an output of the current control loop error amplifier compensator.

Abstract: A power converter includes first and second circuit modules, a first capacitor, a second diode and a control module. The first circuit module includes a switching element in parallel with a first diode. The second circuit module includes a first inductor and the first circuit module. The inductor is in series with the first circuit module. The first capacitor is in parallel with the second circuit module. The second diode includes a first terminal and a second terminal, where the first terminal is in series with the second circuit module and the first capacitor, and the second terminal is coupled to a second power terminal. The control module varies one or more of the first capacitor and the first inductor based on at least one of a current of a load circuit or an input voltage. A resonating waveform is generated by a resonant circuit of the second circuit and is used by the control module to turn off the switching element under zero-current and zero-voltage conditions.
