Abstract: A soot sensing system includes a soot sensor having a first element, and circuitry to an amount of soot accumulated on the element and to control heating of the element in response to the soot accumulation. An electrostatic repelling voltage (ERV) may be applied to a sensor/heater element(s) during a contamination prevention mode (CPM) to repel ash and reduce contamination of the sensor. A pulsed heating voltage (PHV) may be applied to the elements during the CPM and a pulsed ERV may be applied to the elements during the “off” period of the PHV. All voltage to the elements may be turned off during the CPM and the elements may be floating/ground. A PHV may be applied to the elements during the CPM and no voltage may be applied to the elements during the “off” period of the PHV. A heating voltage may be applied to the elements during a CPM corresponding to a cold start.

Abstract: Systems and methods for six-degree of freedom (6-DoF) pose estimation of a user input device, e.g., in a three-dimensional (3D) display system rendering interactive augmented reality (AR) and/or virtual reality (VR) experiences include the user input device capturing, via a camera disposed at a forward-facing tip of the user input device, images in a direction that the user input device is directed and determining, via an inertial measurement unit (IMU), motion of the user input device in three-dimensional (3D) space. The user input device may then determine pose information associated with the user input device based on the images and motion of the user input device. The determination of the pose information may be via usage of at least one of a neural network model, estimation model trained on a set of unique and identifiable patterns, and/or an estimation model trained on a dataset of images.

Then, aggregating the determined subset of the multiple machine learning models to generate an aggregated subset of machine learning models that is customized to the corresponding client computer system.

Abstract: A method of providing an alert to a user of a vehicle includes determining a change in a vehicle operating state, determining if a remote electronic device is detected within the vehicle, and providing an alert to a user if certain conditions are met. An alert is provided if: a) the change in vehicle operating state was from on to off and a phone was detected within the vehicle; or b) the change in vehicle operating state was from off to on and phone was not detected within the vehicle.

Abstract: An antiseptic medical cap that may include a base, a sidewall, and a chamber configured to receive a proximal end of a medical fluid port having an opening. The antiseptic medical cap, in some instances, may include an insert having a gas-releasing anti-microbial compound and/or include a nitric oxide-releasing system that is configured to be positioned at least partially through the opening of the medical fluid port when the antiseptic medical cap receives the proximal end of the medical fluid port into the chamber.

Abstract: A slotted waveguide array (SWA) antenna is provided for emitting electromagnetic radiation. The antenna includes a base, a pair of brackets, a pair of spars, a plurality of waveguides, and a radome. The base provides longitudinal and lateral support for the antenna on a platform.

Abstract: A Person-to-person payments method and system may include receiving a request from a computer network to transfer funds from a first account to a second account, almost instantly. An alias (mobile number or email) is received and is associated with the second account and checked against a database. If the alias exists, multiple options may apply for transferring funds. Next, a secure party identifier is generated and the transfer may be completed. A Payments Switch Module may also communicate with a Third Party Payment Service Provider a request from a Sending or Receiving Financial Institution or party, to send or receive funds from a specific account held by the Third Party Payment Service Provider. This may occur on an adhoc, automatic, or scheduled basis enabling management of ‘personal cash concentration.’ This feature with the Third Party Payment Service Provider be characterized as a “Bring it Home” feature of the system.

Abstract: A model predictive controller for a performing stateless prediction. Using dosed form algebraic expressions for the step test in a dynamic matrix eliminates the requirement for individual calculation on each element. With both the dynamic matrix and the vector of predicted errors written in terms of discrete algebraic equations, the control law is written as a function of the current state of the system. The control law is then be reduced to its minimal form, which leaves the next control action to be a function of the system parameters, the past errors, and the past control actions. Since the system parameters are constant, this controller is then be reduced into a single discrete equation. This greatly reduces the computations required in each control loop iteration.

Abstract: Embodiments provide a method for obstacle avoidance in a mobile robot. Images of objects are captured with mobile robot image sensors with a floor level perspective. Data corresponding to the images is used to train a neural network. The identified objects are classified by indicating whether the objects are a potential hazard. In one embodiment, an image sensor on a robot provides intensity and depth data for each of a plurality of pixels of the images. The intensity and depth data are fused to produce fused data. The fused data is then used to train the neural network.
