In an illustrative example, the articulating wrist may adjust vertically to permit secure sealing of the suction attachment to a local vehicle roof surface. Each of the articulating wrists may couple to a corresponding distal end of one of the leg members via, for example, a ball joint. The wrist angle relative to the leg member may be releasably locked by hand operation of a locking control that, for example, also locks the angle of the wrist relative to the suction attachment. Some systems may advantageously be quickly, releasably and securely mounted from non-planar and/or irregularly shaped vehicle surfaces, for example, roofs, roll cages, hulls, doors, hoods, and bodies.



Deformable energy absorber with deformation indicator

Deformable energy absorber with deformation indicator

Apparatus and associated methods relate to fall-protection safety connector having alignment indicators located on both a static end and a dynamic end of a deformable energy-absorbing device that when deformed visually presents the alignment indicators as misaligned. In an illustrative embodiment, the fall-protection safety connector may be configured to securely connect to a securement member. In some embodiments, a user may connect to the fall-protection safety connector by attaching a lanyard to an aperture coupled to the dynamic end of the deformable energy-absorbing device. Before using the fall-protection safety connector, the user may visually inspect the alignment of the alignment indicators to ascertain the readiness of the connector. Misaligned alignment indicators may advantageously indicate to the user that the remaining energy-absorbing deformation capability of the connector may be below a predetermined specification.



Linear Variable Differential Transformer

A linear actuator comprising a first assembly, a second assembly, and a magnetic sensor. The second assembly is linearly movable with respect to the first assembly such that the linear actuator is configured so as to be in one of a plurality of linear positions. The first assembly and the second assembly cooperatively define a magnetic pathway. The magnetic pathway is configured to vary in length with linear movement of the first assembly with respect to the second assembly. The magnetic sensor is configured to output a signal indicative of the magnetic field flux routed via the magnetic pathway.



Hand-driven ratchet strap assist device

Hand-driven ratchet strap assist device

Apparatus and associated methods relate to a ratchet strap system configured with a ball-shaped handgrip adapted to manipulate a ratchet strap drive shaft. In an illustrative example, the handgrip may include a substantially spherical distal portion coupled to the drive shaft via a substantially cylindrical neck member. The handgrip may, for example, be configured for after-market installation by receiving a shaft extension member of the drive shaft. Some handgrips may include opposing radial apertures for a retention pin to longitudinally fix the handgrip to the shaft extension member. A pliable resilient member disposed at the distal end may prevent decoupling prior to tensioning the strap. In various embodiments, the deployment time of a ratchet strap system may, for example, be reduced by using the handgrip to facilitate initial winding of a load securing strap, and to wind excess strap length for storage in conjunction with an elastic retaining loop.

Retractable hard panel cover and associated storage container

Apparatus and associated methods relate to a storage container and storage container lid configured for stowage and extraction of panels, the panels having complementary mating interfaces that cause the panels to stack onto one another as the panels enter the storage container lid, and to couple to one another as the panels are extracted from the storage container lid. In an illustrative example, the mating interface for the panels may include a first linearly decreasing section, a linearly increasing section, and a second linearly decreasing section that complements the mating interface of an adjacent panel. The panels may slide along a channel into and out of an opening in the storage container lid. A panel storage system may advantageously store panels in the lid of the storage container, while still providing access to the contents of the storage container by opening of the lid.

Craige Thompson and his team are in a different league altogether

In my many years as a telecom engineer in the corporate world, I've worked with quite a few so-so patent attorneys. Craige Thompson and his team are in a different league altogether. Now that I'm paying for these patents myself to further the efforts of my own businesses, I am pleased to say it has been money well spent. Craige got the first patent approved with remarkable skill. Now, a second patent for another business has just been launched. It's been a pleasure to work with folks who not only know the patent ropes but get the engineering and technical aspects. I would highly recommend Thompson Patent Law.
