A system includes a heat sink, a semiconductor device, a layer of thermal interface material (TIM) disposed between the heat sink and the semiconductor device, and a fastener system that couples the semiconductor device, the layer of TIM, and the heat sink together. The TIM may facilitate dissipation of heat generated by the semiconductor device via the heat sink during operation of the semiconductor device. The fastener system includes a first Belleville-type washer configured to cooperate with the TIM, which flows when heated beyond a threshold temperature, to maintain a substantially constant coupling force between the semiconductor device and the heat sink during operation of the semiconductor device.

An electrical bus assembly includes a frame and a plurality of bus bar carriers connected to the frame. The bus bars are supported by the bus bar carriers in parallel spaced-apart relation. A first retainer cap is secured to a first one of the plurality of bus bar carriers located adjacent a first end of the frame. A second retainer cap is secured to a second one of the plurality of bus bar carriers located adjacent a second end of the frame. The first and second retainer caps limit axial movement of the bus bars relative to the plurality of carriers sufficiently to prevent escape of the bus bars from the carriers. A bus bar connector is also disclosed for supplying power to or from the bus bars. An electrical bus system includes a first and second bus bar assemblies and a jumper connector assembly.

Electrostatic charge grounding is achieved by connecting an outer surface touchscreen conductive coating to a grounded conductor in a graphics terminal using an electrostatic charge routing system that provides a path for electrons that accumulate on the conductive coating to pass through one or more non-conductive elements in the graphics terminal. The grounded conductor can be a bezel made of metal or another conductor, a conductive paint layer applied to a bezel or other graphics terminal element, a metal spline pin or a metal screw. The electron path defined by the electrostatic charge routing system can include conductive and dissipative elements such as metal spline pins, metal screws, conductive epoxy, conducting plastic elements providing a short, closed electron bridge.

A controlled motion system having a plurality of movers controlled as they travel along both smart and simple sections of a track. The controlled motion system comprises a control system for controlling the speed of a mover as it travels along a simple section, and permits the pitch or distance between movers to increase or decrease as they travel along a simple section. In a preferred embodiment the controlled motion system includes at least one coupling feature having a driving feature on a simple section for engaging and operably driving a driven feature on each mover such that positive control of each mover is maintained throughout its transition from a smart section to a simple section.

Techniques to facilitate protecting control programs used in an industrial automation environment are disclosed herein. In at least one implementation, control system content provided by a primary entity is received along with a primary security authority provided by the primary entity, wherein the primary security authority defines primary usage rights for the control system content granted to a secondary entity. A secondary security authority provided by the secondary entity is received, wherein the secondary security authority defines secondary usage rights for the control system content that further restrict the primary usage rights. A request is received from a user associated with the secondary entity to perform an action associated with the control system content, and the request is processed with the secondary security authority to determine if the user is authorized to perform the action associated with the control system content based on the secondary usage rights.

Techniques to implement beacon-based access authorization to industrial assets in an industrial automation environment are disclosed herein. In at least one implementation, each industrial asset has one or more beacons that broadcast signals enabling a mobile device to measure its distance from the broadcasting beacon. Each signal also can include access level data defining access permitted for various users, depending on the users authorization level and the calculated distance between the mobile device and the broadcasting beacon. In some implementations the mobile device can provide directions to the user to enable an otherwise disallowed operation. Access to industrial assets is thus limited by the calculated mobile device distance from the industrial asset and the users authorization level.
