Abstract: Additive manufacturing's reliance on embedded computing renders it vulnerable to tampering through cyber-attacks. Sensor instrumentation of additive manufacturing devices allows for rigorous process and security monitoring, but also results in a massive volume of noisy data for each run. As such, in-situ, near-real-time anomaly detection is challenging. A probabilistic-model-based approach addresses this challenge.

Abstract: A subassembly for efficiently and reliably assembling a high performance electronic device. The electronic device may include numerous cabled interconnects in a subassembly that is subsequently mechanically and electrically connected to a PCB populated with high performance electronic components. First ends of cables in the cabled interconnects may be terminated by a first type of connector configured for connection to the PCB via a downward force. The second ends of the cables may be terminated with a second type of connectors that may make connections to other portions of an electronic system incorporating the electronic device. The connectors at the first ends of the cables may be releasably held within an organizer. The connectors may be simply mounted to the PCB by positioning the organizer with respect to the PCB, releasing the connectors from the organizer, and pushing the connectors into engagement with mounting locations on the PCB.

Abstract: A security device is disclosed including a substrate and one or more focusing elements or lens structures located on one side of the substrate. The security device includes a plurality of image elements associated with each focusing element wherein the image elements include at least first and second groups of image elements. Each image element may be composed of pixels located in an object plane to be viewable through the associated focusing element. Each image element comprises a diffractive grating element or sub-wavelength grating element which when illuminated by a light source generates a diffraction image observable at a range of viewing angles around the device. Image elements of the first group are visible in a first range of viewing angles and image elements of the second group are visible in a second range of viewing angles. The security device is particularly suitable for use on security documents, such as banknotes. A method of forming a security device is also disclosed.

Abstract: An example build material spreader for a three-dimensional (3D) object printer has a spreader surface to contact a build material and spread the build material in a build material layer by translating the build material spreader through a bed of the build material to shear the build material and form a smooth exposed surface of the build material layer. The spreader surface has a surface energy less than a maximum surface energy.

Abstract: Systems and apparatuses are described for portable, solar-powered power generation. The systems and apparatuses include a plurality of solar panels affixed to a shipment container or box similar thereto. The solar panels may be stored within recesses along the sides of the shipment container and protected by protruding frames extending along the outer perimeters of the shipment container sides. The solar panels may be maneuvered via manual or power-aided systems for positioning the solar panels for receiving sunlight to facilitate the solar-powered power generation. The solar-generated power is controlled by an electrical control system for regulating and monitoring the generated power. A telescopic pole including an electrical load (e.g., a plurality of lights) may be raised upward from within the shipment container, and the generated solar power may be directed to the lights for providing illuminance to a surrounding area. Other loads may be powered by the system, as desired.

Abstract: An apparatus for transporting media in a printer helps reduce vibration and noise in the printer. The apparatus includes a pair of brackets secured to a printer surface, a shaft, a first portion of the shaft being secured within one of the brackets and a second portion of the shaft being secured within the other bracket, a roller mounted about the shaft for rotation about the shaft, and a pair of vibration dampeners, one vibration dampener being interposed between the first portion of the shaft and the one bracket, and the other vibration dampener being interposed between the second portion of the shaft and the other bracket.

Abstract: A lever-style de-latch mechanism for a pluggable electronic module, such as an SFP MSA fiber optic transceiver or other pluggable optoelectronic or electronic module. The mechanism is easily accessible to an operator and does not require any tools to operate. The mechanism uses rotational motion of a lever about a horizontal axis transverse to a horizontal direction of elongation of a module, or about a vertical axis (relative to a module extending in a horizontal plane), to cause translational motion of the de-latch actuator. Mechanisms including both T and bail latch style levers are provided. The lever may be adjacent to, or extend beyond, the front/face of the module's housing for tool-free accessibility and operation. The mechanism may allow the user to apply force to actuate the mechanism in a direction that does not oppose a withdrawal and/or module ejection force.

Abstract: Apparatus and methods associated with power adapter identification are described. In one embodiment the apparatus includes an adapter plug having at least two contacts and at least one circuit component connected to the at least two contacts.

Abstract: Methods and systems relating to a LCD are disclosed. In one exemplary embodiment, the LCD has an active state and an inactive state. The inactive state is configured to produce a desired residual image. The active state is configured to produce a desired non-residual image.

Abstract: A push-button style de-latch mechanism for an SFP MSA fiber optic transceiver or other pluggable optoelectronic or electronic module. The mechanism is readily accessible to an operator and does not require any tools to operate. The mechanism uses translational motion of an actuator to de-latch the module from its receptacle. The actuator is slidable from a first (inoperable) position in which the actuator extends beyond the housing face for tool-free accessibility and operation, to a second position for de-latching the module. The actuator includes a pair of outer legs, each defining a wedge, and an inner leg positioned between the outer legs and having a barb for retaining the actuator on the module. The inner leg deflects to allow the actuator to be easily mounted/demounted from the module's housing for assembly/repair/replacement purposes. Modules and module assemblies including such de-latch mechanisms are also provided.

Abstract: Holographic and diffractive security devices and documents carrying security devices as well as system, apparatus, and method for making and using security devices. Security devices provide at least one type of security feature in form of secret, hidden, or covert security feature, not visible to a normal unaided human eye. Covert security features may be any graphic or symbolic representation. One or multiple security features may be provided on any single security device in any combination. Covert feature is revealed either when a decoder device is used with the security device, or when the security device is oriented and viewed in predetermined manner. Embodiments may provide a second overt or non-covert security device in the form of a diffractive or holographic image or graphic that is visible to the unaided eye without use of any decoder or special viewing conditions.

Abstract: Device, method, and system for recording diffractive high resolution text, pictorial, and/or other graphical information is provided which is particularly suited to recording information that would be difficult to reproduce by typical counterfeiting methods. The information recorded may be used to authenticate the recorded item, or indirectly, an item to which the recording is attached. Such items may include legal, financial and commercial instruments, credit cards, and packaging for such items as software, art, and other items where forgery of the item may be a concern. In one embodiment of the invention light is selectively passed by a shutter, and a spatial filter then cleans the beam to remove undesirable frequency components.
