Abstract: A novel perimeter indication rod assembly includes a perimeter indication rod for pivotal connection to a ski pole by a rod positioning mechanism. The rod positioning mechanism is configured to selectively hold the perimeter indication rod in extended or stowed position. The distal extent of the perimeter indication rod visually indicates a desired lateral safety distance from the skier.

Abstract: Aircraft handlers include a plurality of undercarriage support assemblies. Each undercarriage support assembly includes a body, a translation assembly operably attached to the body, and a support member operably coupled to and extending from the body. The support member comprises a support region configured to engage and operably support at least a portion of an undercarriage of an aircraft. The translation assembly is configured to support the undercarriage support assembly on a ground surface and permit the undercarriage support assembly to translate along the ground surface. The aircraft handlers further include one or more drive assemblies configured to move the aircraft handler along the ground surface, in which each drive assembly comprises the translation assembly of an undercarriage support assembly. Methods comprise supporting the undercarriage of the aircraft with the aircraft handler and moving the aircraft along the ground surface with the aircraft handler.

Abstract: The presently disclosed subject matter is directed to an assay that detects and quantitatively determines the activity of a lytic peptide that exhibits antimicrobial activity, such as LL-37. Particularly, the assay comprises inducing and/or transfecting bacteria to produce high levels of an enzyme, such as ?-galactosidase. The bacteria are then preserved by lyophilization. After a desired amount of time, the bacteria are hydrated with a target sample from a subject suspected of having a specific disease or disorder characterized by an increase in levels of lytic peptide. In the presence of lytic peptide, the enzyme is released from the interior of the bacteria, which can then be detected by alteration of the enzyme substrate. In the absence of lytic peptide, the enzyme remains within the bacteria and no detection of the enzyme occurs.

Abstract: A method and system for managing group calling from a wireless mobile application is provided. One or more wireless mobile devices are provided that access a wireless network. At least one user can create at least one group call using one of the mobile devices using swipe gestures to create groups from a user's contact list and establishing the at least one group call over the wireless network.

Abstract: A method of making an inkjet printhead comprises forming at least one ink ejection element 18 on a surface 14 of a substrate 10 and forming a slot 12 in the substrate to provide fluid communication between an ink supply and the ink ejection element. A protective coating 26 is applied to the surface of the substrate prior to forming the slot. The protective coating comprises a non-polymeric material which is capable of forming a covalent bond with the substrate and is removed from the substrate without damaging the ink ejection element following slot formation.
