Drainer for drying wet items

Colander

Collapsible wheeled container

Collapsible containers and a method of their manufacture are disclosed herein. The collapsible containers have one or more collapsible wall sections and a stiff upper and lower tier. The wall sections have living hinges and three or more tiers between the hinges. A thermoplastic elastomer layer may join separately made portions of the container together. The containers may be made by molding and overmolding. The containers include inter alia bulk liquid containers, jugs, tubs, baskets, bottles, and food containers. The method of manufacturing includes placing a container component and a matching container body comprising a stiff first tier, a stiff second tier, and a collapsible wall section in a mold; assembling the container body with the container component to close one end of the container body; and overmolding a thermoplastic layer around the container body and the container component.

Collapsible shape-retaining containers

Collapsible laundry basket

Collapsible indoor and outdoor containers having a collapsible wall section with shape-retaining characteristics are disclosed. In particular, collapsible coolers, fish bins, and wheeled vertical bins are provided. The collapsible wall section may include foldable tiers of a flexible material, each tier having at least one stable, relatively expanded position and at least one stable, relatively collapsed position; and an intervening, non-folding tier composed of a different, relatively stiff or rigid material. The coolers, fish bins, and wheeled vertical bins are each advantageously provided with a collapsible insert container that nests within and collapses together with a shell of the respective container, the respective wall folds of the shell and insert meshing together to result in a combined collapsed vertical dimension as small or nearly as small as that of the collapsed shell alone.

Collapsible multi-purpose containers

Collapsible cup

A collapsible container, particularly a cup or mug having a flexible body having a top tier, middle tier and a bottom tier is disclosed. The bottom tier has a base. The container has a first living hinge between the top and middle tiers and a second living hinge between the middle and bottom tiers. A rigid, preferably metal, plate is at least partially embedded in the bottom tier that makes the otherwise flexible base rigid. The container can have a rigid metal cladding around the top tier and a handle made of flexible material. The collapsible container may be made by injection molding.

Collapsible household containers having a foldable wall section with shape-retaining characteristics are disclosed. In particular, collapsible laundry baskets, buckets, colanders, dish drainers, and cups are provided. The folding region may include foldable tiers of a flexible material, each tier having at least one stable, relatively expanded position and at least one stable, relatively collapsed position; and an intervening, non-folding tier composed of a different, relatively rigid material.

A switch mode power supply (voltage converter) is adapted as a current-mode control buck regulator for different loading conditions. The voltage converter operates in a continuous conduction mode (CCM) during heavy load conditions using pulse width modulation (PWM). When a zero-current detector determines no inductor current during light load conditions (discontinuous conduction mode (DCM) region), the controller initiates adaptive duty control using pulse frequency modulation (PFM). Adaptive duty estimation circuitry provides controllable energy to charge the power inductor to maintain voltage accuracy and maximize efficiency when in the PFM mode. Using clock synchronization and a single control-loop, smooth transition between PFM, PWM, and bypass modes is automatically performed. Clock synchronization from a master oscillator provides a base for frequency division in different operation modes which gives controllable evenly distributed switching harmonics. An inductor zero-current detector triggers an adaptive estimated duty cycle that is synchronized with the master oscillator.

A remotely controlled toy vehicle includes a front assembly, a rear assembly, a drive mechanism, and a roll mechanism. The front assembly and the rear assembly each include at least one wheel and the drive mechanism includes a drive motor configured to drive at least one of the at least one wheel of the front assembly and the at least one wheel of the rear assembly. The roll mechanism includes a roll motor configured to roll one of the front assembly and the rear assembly with respect to the other of the front assembly and the rear assembly.
