Abstract: An apparatus for positioning and retaining a Rogowski coil around a conductor includes a first member configured to receive a first section of the Rogowski coil, a second member configured to receive a second section of the Rogowski coil, and a non-conductive securing structure configured to engage the conductor and retain the first member and the second member in fixed positions relative to the conductor. According to one exemplary embodiment, the apparatus may also include a coupling mechanism configured to permit at least one of the first member and the second member to be moved relative to each other and positioned around the conductor. According to another exemplary embodiment, the securing structure may include a pair of arched elements, wherein each arched element is configured to engage the conductor and retain a corresponding one of the first and second members in a respective fixed position relative to the conductor.

Abstract: An apparatus for positioning and retaining a current transformer, such as a Rogowski coil, about a conductor includes at least two members, a coupling mechanism, and a non-conductive securing structure. Each member of the apparatus includes a respective retention structure configured to receive a respective section of the Rogowski coil. The coupling mechanism is configured to movably deploy at least one of the apparatus members relative to the other and around the conductor, which may be a distribution transformer power node. The securing structure is configured to engage the conductor and retain the apparatus members in fixed positions relative to the conductor and to each other.

Abstract: A drain cleaner is disclosed having a housing with an interior region for storing a flexible drain cleaning cable. The drain cleaning cable can be extended from the drain cleaner and includes a rotatable member within a non-rotating sheath. The drain cleaner includes an engageable drive shaft coupled to the rotatable member. In certain versions, the drive shaft is coupled to the rotatable member through a torque limiting device such as a clutch. Upon engagement of the drive shaft with a rotary power source, a rotating distal end of the flexible cable can be used to dislodge obstructions in pipes. The interior region of the drain cleaner is configured to promote efficient coiling of the drain cleaning cable. The drain cleaner includes additional features for reducing wear of cable and components, and securely retaining the cable to the drain cleaner.

Abstract: A camera control key assembly including a metal housing with a pocket containing a sensor window, a metal strip abutting a side of the sensor window, a spacer positioned to abut the metal strip, at least one capacitive touch sensor abutting the spacer, and a control key set into the pocket of the housing and contacting a first side of the sensor window. Preferably, the plastic sensor window is insert molded into the metal housing making the assembly inherently watertight. The assembly comprises at least one force concentrator on the control key to act upon the sensor window which in turn allows the capacitive touch sensor to register a multitude of different user inputs, including pressure, varied pressure, duration, taps, slides and swipes.

Abstract: A volatile material dispenser includes a housing, a retention mechanism coupled to the housing, and a compatible volatile material refill that includes a first set of dimensions and a wick extending therefrom. An adapter is removeably attached to a portion of the compatible volatile material refill. The retention mechanism non-removeably retains the adapter to the housing when the compatible volatile material refill and adapter combination are inserted therein. Further, when the compatible volatile material refill is removed from the adapter, the adapter prevents incompatible volatile material refills having a second set of dimensions different from the first set of dimensions from being attached to the housing.
