A folding tonneau cover apparatus including a cover assembly and a support frame assembly. The cover assembly having a plurality of rigid panels interconnected in series by a series of flexible hinges preferably made from a laminated woven fabric material. The rigid panels are preferably stiffened by elongated support members secured to the undersides of the respective panels and the top surfaces of portions of the rigid panels are preferably downwardly concave. The cover assembly is secured to the support frame assembly to cover a cargo box of a pickup truck by a plurality of locking members when the support frame assembly is secured to sidewalls of the cargo box. Methods of making a tonneau cover apparatus and methods of folding and unfolding the cover assembly are also disclosed.

Folding tonneau cover apparatus

A folding tonneau cover apparatus including a cover assembly and a support frame assembly. The cover assembly having a plurality of rigid panels interconnected in series by a series of flexible hinges. Elongated support members having hinge support flanges help to secure the flexible hinges to the rigid panels. In preferred embodiments, the support flanges of the elongated support members cooperate with the underside of the respective rigid panels to which the support members are secured, to form a partial enclosure within which a side portion of the respective flexible hinge is secured. The cover assembly is secured to the support frame assembly to cover a cargo box of a pickup truck by a plurality of locking members when the support frame assembly is secured to sidewalls of the cargo box. Methods of making a tonneau cover apparatus and methods of folding and unfolding the cover assembly are also disclosed.

Folding tonneau cover having secured flexible hinge

A tonneau cover apparatus for removable attachment to a cargo box of a pickup truck including a support frame assembly and a cover assembly. The cover assembly includes a plurality of pivotally interconnected rigid panels that can be folded up and secured to the cargo box such that respective upper surfaces of at least two of the plurality of rigid panels reside in an upright folded orientation. The tonneau cover apparatus further includes a mechanism for securing the at least two of the plurality of rigid panels in the upright folded orientation. A method of removably securing the tonneau cover apparatus to the pickup truck is also described, as is an alternate embodiment of the tonneau cover apparatus, wherein the cover assembly includes first and second pivotally interconnected rigid panels and a pair of hinge support mechanisms that generally restrict the way the second rigid panel pivots.

An interface for coupling a dissolved oxygen sensor to a single-use bioreactor container is provided. A dissolved oxygen (DO) window membrane is operably coupled to the single-use container and configured to position a DO sensor at least partially within the single-use container. In some embodiments, a DO window body mounts the DO window membrane at a distal end thereof. The DO window body can include a slide lock for facilitating positioning of a DO sensor within the DO window body. Additionally, the DO window body may include at least one heat exchange fin.

Detachable dissolved oxygen sensor interface for single-use bioreactor/mixer

A multi-stage irreversible sensor coupling is provided. A sensor body includes a sensor and has a sensor body wall and at least one sensor body engagement feature. A clip barrel is configured to slidably engage the sensor body and has at least one clip barrel engagement feature. A wedge clip is configured to slidably engage the clip barrel and has at least one wedge clip engagement feature that is configured to urge the at least one sensor body engagement feature into cooperative engagement with the at least one clip barrel engagement feature when the wedge clip, clip barrel, and sensor body are fully engaged together.

Multi-stage irreversible sensor coupling

A pH sensor for a single-use container includes a plunger sleeve configured to couple to a flange of the single-use container. A plunger is axially movable within the plunger sleeve between a storage position and an operating position. A pH sensing element coupled to the plunger wherein the pH element is disposed within a storage chamber in the storage position and is configured to be exposed to an interior of the single-use container in the operating position. In one example, a temperature sensitive element is disposed within the pH sensor and configured to sense temperature proximate the pH sensing element. In another example, a lock member is coupled to the plunger, where the lock member has a locked position and an unlocked position, the lock member being configured to inhibit movement of the plunger when in the locked position. In yet another example, the plunger includes at least one filling channel that allows access to a reference fill chamber when the plunger is in a filling position.
