Abstract: A method for determining authenticity of a security device of a component in an imaging device includes receiving, by the security device, an authentication challenge including one or more commands and executing, by the security device, the one or more commands in response to receiving the authentication challenge. A magnetic field profile is generated based on current drawn by the security device from a power source while the security device is executing the one or more commands, the generated magnetic field profile indicating an authentication response of the security device to the authentication challenge for use in determining authenticity of the security device.

Abstract: A downspout diverter for diverting collected water, such as rainwater. The diverter either directs the collected water towards a storage tank, such as a rainwater harvesting storage tank to towards an outflow portion. When the collected water is directed towards the outflow portion, the water exits the diverter spilling the water to the ground.

Abstract: Methods, apparatus, and systems are disclosed that determine property recommendations for a user. The methods, apparatus, and systems may also predict when a user is likely to become a property buyer and/or seller to determine when certain property recommendations are to be made. The methods, apparatus, and systems use one or more machine learning algorithms to determine a dynamic preference profile for a user that accurately reflects the user and how the user changes over time. The preference profile takes into account property-related information and user characteristic information as variables for the machine learning algorithm(s).

Abstract: A debris guard for installation on an eavestrough is disclosed. The debris guard includes a frame having a back side, a front side, a length, two ends, a top surface, a bottom surface opposite the top surface, and a water collection portion extending from the front side to the back side and along the length of the frame between the two ends. The water collection portion includes a plurality of holes to allow rainwater to pass through. The water collection portion also includes a plurality of drip legs coupled to the plurality of holes, the plurality of drip legs extending below the bottom surface to provide improved water flow through the eavestrough debris guard. Each of the plurality of holes includes at least one drip leg that provide improved flow through the debris guard.

Abstract: The present invention relates to novel inventive compound device structures, enabling charged-based logic gates. In particular, a switched p-channel and/or n-channel current field effect transistor, a solid state device based on a complimentary pair of a switched p-channel and n-channel current field effect transistors, and/or a solid state device based on a complimentary pair of a p-channel and n-channel current field effect transistors are used for constructing such logic gates. The switched current field effect transistor comprising a source and a drain, wherein the source and drain defines a channel, a diffusion that divides the channel into a source channel segment between the source and the diffusion and a drain channel segment between the drain and the diffusion, a source channel gate that is coupled to the source channel, and a drain channel gate that coupled to the drain channel. These novel device structures provide various improvements over the conventional devices.

Abstract: A processing system employs a processing tool to process workpieces, for example cold working holes and/or installing expandable members into holes. Sensors sense various aspects of the processing. Information regarding performance of the process and/or materials may be stored, for example a hole-by-hole or a workpiece-by-workpiece basis, allowing validation of processing. Information also allows dynamic operation of the processing tool. Analysis of response relationships (e.g., pressure or force versus position or distance) may provide insights into the process and materials, and/or facilitate the real-time feedback including control, alerts, ordering replacement for consumable components.

Abstract: There is described an apparatus and method for inspecting and optionally sorting gemstones. The apparatus includes a nozzle or array of nozzles operatively connected to a vacuum pump such that a gemstone located generally underneath one of the nozzles will be supported against that nozzle by air pressure when a vacuum is applied above the nozzle. A drive system moves the nozzles along a path past a gemstone pick-up location so that a gemstone can be picked up by each nozzle as that nozzle passes the pick-up location. One or more measurement devices are located on or near the predetermined path and configured to measure at least one property of the gemstone. One or more ejection locations are provided on the path at which the vacuum applied to each nozzle is reversible to eject the gemstone from that nozzle. The apparatus may also include a plurality of dispensing bins into which the gemstones are dispensed. The bin into which each gemstone is dispensed is chosen in dependence on the measured property.
