Abstract: A system includes a USB-C receptacle including first and second non-GPIO pins and a USB-C controller including a first GPIO pin connected to a pull-up resistor and a second GPIO pin connected to a pull-down resistor, a pair of non-GPIO pins including a third non-GPIO pin corresponding to the first non-GPIO pin and a fourth non-GPIO pin corresponding to the second non-GPIO pin. The pair of GPIO pins is selectively connectable to the pair of non-GPIO pins using a multiplexer, and liquid exposure detection circuitry configured to cause a first voltage for the first GPIO and a second voltage for the second GPIO to be measured, determine whether the first and second voltages each satisfy a threshold condition, and in response to determining that the first and second voltages each do not satisfy the threshold condition, cause operation of the USB-C receptacle to be suspended.

Abstract: The Osprey Raft is the float on an Angler's Fishing Tackle that has been engineered with electronics: remote communication, a propeller system, and guidance control. It is battery operated and conveys an array of equipment; optional camera for underwater viewing, optional net, optional spare gun, hook(s) and line(s). By a line it still connects an angler's rod. The angler, by means of a remote control console, is able to move around the tackle and extend the cast. The device can be operated with a video monitor attached to the same angler's rod for underwater viewing, it can be adapted to use smart phone with a piscatorial application, providing fishing rules and regulation in whatever locale you choose to fish.

Abstract: A reusable wire guide used to reduce friction and abrasions on conductor insulations while both feeding and pulling conductors through an electrical conduit LB. The wire guide is made of polymer material. It is a one-piece tool that has a curved body with two holding bracket molded to the main body. The Wire Guide is grooved at one end to allow it to be placed directly on the conduit entrance hole lip of the electrical LB. The wire guide is secured to the LB by holding brackets on the wire guide to the existing screw holes on the electrical LB.
