Abstract:
A light emitting diode (LED) display assembly is formed of a translucent plastic housing, a light diffuser film coupled to the translucent plastic housing, a light barrier gasket coupled to the diffuser film, and an LED module coupled to the light barrier gasket. The LED module comprises a plurality LEDs individually controlled for generating a light source to form a graphic on the surface of the translucent plastic housing.
Abstract:
A method and circuit board arrangement for an intrinsically safe portable device includes two or more circuit boards having a frame structure that forms a contiguous boundary around a space between the circuit boards. In the space there are circuit components mounted on both circuit boards, and a connector that connect the two circuit boards. An encapsulant material fills the space bounded by the frame structure between the circuit boards to exclude airborne material from coming into contact with the encapsulated circuit components.
Abstract:
A slide actuation apparatus includes a bezel configured to maintain a configuration of the slide actuation apparatus. The bezel also includes an opening on an external surface. The slide actuation apparatus also includes an actuator configured to move within a compartment formed by the opening and a sliding rail configured to guide movements of the actuator along a surface of the sliding rail. The sliding rail is compressible downward in response to movement of the actuator along the surface of the sliding rail. The slide actuation apparatus further includes a slide contact configured to make an electrical connection to a flexible circuit and configured to provide a signal of a change to a circuit board of an attached computing device in response to downward compression of the sliding rail.
Abstract:
An enclosure includes a seal co-molded to a first material to form a sub-assembly in which the first material is securely adhered to the seal. The seal is designed to collapse in a specific direction during an injection molding process. The enclosure also includes a second material over-molded on the sub-assembly during the injection molding process. The seal is compressed in the specific direction during the injection molding process to produce a consistent wetting at least at one desired perimeter joint between the seal and the over-molded second material, forming the bi-material enclosure. The first material and the second material are dissimilar materials with different thermal expansion qualities.
