Title: Generating and reading optical codes with variable density to adapt for visual quality and reliability
Inventor: SHARMA RAVI
IPC: G06T1/00
Filed: 2019-02-25
Abstract: A variety of arrangements for producing 2D optical codes, allowing for variable spatial density of marking elements, are detailed. Such arrangements achieve highly reliable data transfer (in conjunction with a compliant decoder) while efficiently using a small number of marking elements (dots), and/or a low density of dots per unit area. Most of the codes are formed from (a) a message component that conveys a payload, and (b) a reference component that enables geometric synchronization. Dots can be allocated to serve one or both of these purposes. In a particular embodiment, parameters of an optical code are optimized to achieve improved signal robustness, reliability, capacity and/or visual quality. An optimization program can determine spatial density, dot distance, dot size and signal component priority to optimize robustness. An optical code generator employs these parameters to produce an optical code at the desired spatial density and robustness. The optical code may be merged into a host image, such as imagery, text and graphics of a package or label, or it may be printed by itself, e.g., on an otherwise blank label or carton. A great number of other features and arrangements are also detailed.

Title: Systems and methods for assigning tasks in a neural network processor
Inventor: NORDEN ERIK
IPC: G06N3/04
Filed: 2019-04-04
Abstract: Embodiments relate to managing tasks that when executed by a neural processor circuit instantiates a neural network. The neural processor circuit includes neural engine circuits and a neural task manager circuit. The neural task manager circuit includes multiple task queues and a task arbiter circuit. Each task queue stores a reference to a task list of tasks for a machine learning operation. Each task queue may be associated with a priority parameter. Based on the priority of the task queues, the task arbiter circuit retrieves configuration data for a task from a memory external to the neural processor circuit, and provides the configuration data to components of the neural processor circuit including the neural engine circuits. The configuration data programs the neural processor circuit to execute the task. For example, the configuration data may include input data and kernel data processed by the neural engine circuits to execute the task.

Title: Air-cooled heat exchanger cleaning and temperature control apparatus and method
Inventor: AL-OTAIBI ABDULLAH
IPC: F28F27/02
Filed: 2019-05-02
Abstract: A method and system for the maintenance and operation of air-cooled heat exchangers in climactic extremes of hot and cold ambient air temperatures which includes the permanent installation of a plurality of spray tubes provided with spaced-apart nozzles positioned between the finned heat exchange tubes and longitudinally aligned within the region of the finned-tube pitch. In one mode of operation, the forced air fan is stopped and temperature-controlled pressurized water with an optional cleaning agent is discharged from the nozzles to dislodge dirt and debris from the finned surfaces while simultaneously cooling the hot process liquid. When high ambient air temperatures preclude the forced air fans from achieving the required cooling of the process liquid passing through the ACHE, refrigerated pressurized cooled water and compressed air in the form of a mist is discharged from the nozzles. When low ambient air temperatures would reduce the temperature of the process liquid to an unacceptable level, pressurized heated air is discharged from the nozzles. Temperature sensors and associated automated programmed control systems can advantageously be employed to adjust the volume and temperature of the respective fluids discharged through the spray nozzles, or the system can be manually controlled by an operator based upon the temperature and pressure of the process fluid discharged from the ACHE.

Title: A system for drying a paste-based crafting mmedium during three-dimensional printing
Inventor: MOOSBERG MATS
IPC: B29C64/165
Filed: 2019-05-03
Abstract: This invention relates to three-dimensional printing. This invention in particularly relates to a system for drying a paste-based crafting medium during three-dimensional printing and a method thereof. The system can comprise a dual printhead comprising a first dispensing nozzle for depositing the filament material for a mold layer in a flowable fluid form and a second dispensing nozzle for depositing the crafting medium, which is in a paste form. The system also includes a drying means which can be a heating system or a drying apparatus, that in some embodiments can be attached to the printhead. The three-dimensional imaging process for making objects, preferably metal objects or ceramic objects, on a layer-by-layer basis under the control of a data processing system is disclosed. The drying of the object or mold is crucial in the three-dimensional imaging process because it can affect the overall quality of the object. A solution to this problem is achieved in the present invention by using a drying step after finishing each layer of the object (both mold and paste). This is achieved in some embodiments by using a drying apparatus comprising a radiating heater and air circulation fan mounted on to the moving print head. The print head can repeatedly scan the printed layer and apply heat and air circulation to improve drying in a controlled manner. This system and method provides improved evenness in the drying and reduces the risk of cracks developing in the deposited object, and also reduces the risk of further problems during the subsequent processing steps to provide the finished object.

Title: A method of generating a mold and using it for printing a three-dimensional object
Inventor: MOOSBERG MATS
IPC: B29K105/00
Filed: 2019-05-03
Abstract: This invention relates to three-dimensional printing. This invention in particular relates to a method of generating mold and printing a three-dimensional object. The mold thickness is controlled and holes are generated in the mold surface for releasing moisture easily. The mold surface having holes is designed initially digitally and then combined with the three-dimensional model before printing the three-dimensional object. In case the thickness of the mold surface is more then it reduces the overall quality of the three-dimensional object. When the model is enclosed inside the mold, there will be some residue moisture in the model even if the drying apparatus can improve this by drying layer by layer. This affects the final quality of the part. A solution of these problems is provided in the present invention. The thickness of the mold layer is between 0.5 to 1 mm and holes having 0.1 to 0.4 mm diameter. The holes are evenly distributed on the mold. The mold having the holes is prepared from which moisture can easily escape. A method of digitally generated a mold having thin layer and holes is used for fabricating three dimensional objects with high precision and quality.

Title: Systems and methods for polluting phishing campaign responses
Inventor: WILCOX BRIAN MICHAEL
IPC: H04L12/58
Filed: 2019-06-25
Abstract: Techniques for polluting phishing campaign responses with content that includes fake sensitive information of a type that is being sought in phishing messages. Embodiments disclosed herein identify phishing messages that are designed to fraudulently obtain sensitive information. Rather than simply quarantining these phishing messages from users' accounts to prevent users from providing "real" sensitive information, embodiments disclosed herein analyze these phishing messages to determine what type(s) of information is being sought and then respond to these phishing messages with "fake" sensitive information of these type(s). For example, if a phishing message is seeking sensitive credit card and/or banking account information, some fake information of this type(s) may be generated and sent in response to the phishing message. In various implementations, a natural language processing (NLP) model may be used to analyze the phishing message and/or generate a response thereto.
