Abstract: An implantable medical lead may include an electrode at a distal portion of the lead that is configured to monitor or provide therapy to a target site. The lead may include a visible indicator that is visible to the naked eye of a clinician at a medial portion of the lead that is configured to indicate when the electrodes of the lead are longitudinally and radially aligned properly to monitor or treat the target site. A clinician may insert the lead into the patient using an introducer sheath inserted to a predetermined depth into the patient and subsequently aligning the distal portion of the lead by orienting the indicator at an entry port of the introducer sheath.

Abstract: Disclosed herein are compounds of formula I: or a pharmaceutically acceptable salt thereof, where the variables are as defined herein. These compounds are useful in treating RET associated cancers. Formulations containing the compounds of formula I and methods of making the compounds of formula I are also disclosed.

Abstract: A resilient, shock absorption assembly that mounts between available sail rigging lines and a boat hull. In one assembly, a piston is resiliently biased relative to a housing and contained spring to permit reciprocating movement. Couplers at distal ends of the piston and housing attach to suitable rigging lines and/or the boat. In other assemblies, resilient elastomer cores bias movement of a piston or cable. In another assembly fitted within a main sail boom, a cable biases the boom rigging lines. In still another construction, an “A-shape”, mast replacement framework is secured to pivot from a boat's deck. Resiliently biased cables act as a mast and support a sail boom. One or more separate resilient assemblies can be coupled to the sail. The cable mast and rigging lines are thus made resilient to counterbalance the boat against heeling with the presence of rough water and gusty winds.

Abstract: In the electronic equipment shelter disclosed herein, protection of electronic equipment from both normal and abnormal environmental conditions, including severe electromagnetic pulses, is provided by employing a construction in which panels having inner and outer aluminum skins are joined together in an assembly employing extruded box tubes at each edge with the outer skins being welded to each other and to the tubes so that a complete conductive envelope is obtained. The necessary door opening is made electromagnetically unitary with the main shelter body by metal spring finger gaskets which are compressed by means of a multiplicity of linked dogging assemblies all around the door frame.

Abstract: Disclosed is an improved folding and loading mechanism for small, limp, sheet-like articles. A pair of pivotal support trays are biased to form a horizontal platform, upon which each sheet-like article is placed and then folded by pivoting flippers. After folding, a propulsion mechanism moves from a rest position and pushes the support trays out of the way and further pushes the folded article into a carton residing below the platform. Upon return of the propulsion mechanism to a rest position, the biasing on the support trays returns them to again form the horizontal platform. The propulsion mechanism can be a separate stomper member positioned above the platform.

Abstract: In the fabrication of a resistance heater for a carton for packaging a pizza, an aluminum metallized sheet is adhered to a paperboard panel, a generally U-shaped strip of arc-sprayed zinc is applied to three edge portions of the upwardly facing electrically conductive metal layer of the metallized sheet, the interconnecting portion of the U-shaped strip and the immediately underlying metal layer are severed, and the metal layer is severed along a line extending adjacent the same interconnecting portion to the side thereof enclosed by the U-shaped strip, so that each of the severed sections of the interconnecting portion serves as a terminal for a corresponding leg portion of the U-shaped strip comprising the electrodes for the intermediate region of the metallized sheet.

Abstract: A paperboard carton for packaging a pizza is provided with a substantially rigid, pizza-supporting electrical-resistance heater insert comprising a corrugated paperboard panel having laminated thereto a sheet of vacuum-metallized glassine. Arc-sprayed zinc bus bars extend over opposed edges of the metallized sheet and serve as electrodes for conducting electricity through the sheet as the resistor element. Electrical energy is supplied to the electrodes by a removable terminal clip that extends through an opening provided in a side wall of the carton and both electrically and mechanically engages suitably presented electrode terminals. An insulating sheet of coated paper extends over the metallized surface, the electrodes, and the bus bars, and serves as the immediate support surface for the pizza.
