A RAMP-radio frequency (RAMP-RF) assembly is provided and includes an RF panel including a microstrip interface, a plate including a stripline interface and a microstrip-to-stripline transition element operably connectable to the microstrip interface and to the stripline interface.

Provided are interconnects for interconnecting a set of battery cells, assemblies comprising these interconnects, methods of forming such interconnects, and methods of forming such assemblies. An interconnect includes a conductor comprising two portions electrically isolated from each other. At least one portion may include two contacts for connecting to battery cells and a fuse forming an electrical connection between these two contacts. The interconnect may also include an insulator adhered to the conductor and mechanically supporting the two portions of the conductor. The insulator may include an opening such that the fuse overlaps with this opening, and the opening does not interfere with operation of the fuse. In some embodiments, the fuse may not directly interface with any other structures. Furthermore, the interconnect may include a temporary substrate adhered to the insulator such that the insulator is disposed between the temporary substrate and the conductor.

A foldable modular flex circuit for attaching to at least one component. The flex circuit may comprise a central area and at least one tab depending from the central area. The central area may comprise a cable attachment section configured to electrically couple to at least one coaxial cable. A first tab may depend from the central area and is configured to electrically couple to a ball grid array (BGA) of the component. A second pair of tabs may depend from the central area and are configured to electrically couple to an additional at least one component, wherein each tab depends substantially perpendicular from the central area.

A single cell power unit for a motorized surgical power tool includes a single cell power unit enclosure. A high temperature battery cell is mechanically supported within and disposed at about a center of the single cell power unit enclosure. An electrical connector having a plurality of connector pins is configured to couple to a mating electrical connector of a tool part having a motor. A motorized surgical handpiece tool which prevents the motor from operating when the power unit is removed, a method to start a multi-phase brushless sensorless motor of a surgical hand piece tool in a controlled manner, a power unit for a motorized surgical power tool with a battery insulated by a flexible circuit boards, and a safety switch system for a motorized surgical power tool with a lever magnet motor speed control are also described.

An antenna apparatus includes a plurality of circuit boards, an antenna element, and an electronic component. A plurality of the antenna elements are arranged along the surfaces of the plurality of circuit boards. The electronic component is arranged along the surfaces of the circuit boards, configured to be larger in size in the thickness direction of the circuit boards than a gap between the antenna elements, and connected to the arranged antenna elements via a high-frequency transmission circuit. The plurality of circuit boards are arranged with component mounting surfaces arranged oppositely to each other and, for each pair, the positions corresponding to the electronic component are misaligned in the surface direction of the circuit boards.

Systems and methods disclosed herein include a light engine circuit board including a flexible substrate having a first interconnect region located at a first end of the flexible substrate and a second interconnect region located at a second end of the flexible substrate, in which the first interconnect region and the second interconnect region each comprise one or more solder strips, and one or more LEDs on the flexible substrate.
