Abstract: This disclosure describes a system for automatically transitioning items from a materials handling facility without delaying a user as they exit the materials handling facility. For example, while a user is located in a materials handling facility, the user may pick one or more items. The items are identified and automatically associated with the user at or near the time of the item pick. When the users enters and/or passes through a transition area, the picked items are automatically transitioned to the user without affirmative input from or delay to the user.

Abstract: An air supply control arrangement for a heavy-duty vehicle comprising a lift axle includes a brake chamber. An electronically controlled brake valve device allows pressurized air to be passed to the brake chamber of the lift axle. A pressurized air source supplies pressurized air to the electronically controlled brake valve device along a supply passage. A pilot control valve provided between the pressurized air source and the electronically controlled brake valve device can restrict air flow through the supply passage. A pressure-responsive element actuates the pilot control valve when the pressure in the lift bellow is increased so that the lift axle is raised to a lift condition. The pressure-responsive element closes the pilot control valve. When the pressure in the lift bellow is reduced so that the lift axle is lowered to a ride condition then the pressure-responsive element is deactivated to allow opening of the pilot control valve.

Abstract: This disclosure is directed to techniques in which a first user in an environment scans visual indicia associated with an item, such as a barcode, before handing the item to a second user. One or more computing devices may receive an indication of the scan, retrieve image data of the interaction from a camera within the environment, identify the user that received the item, and update a virtual cart associated with the second user to indicate addition of the item.

Abstract: A biometric identification system acquires a multimodal image. The system is trained to determine three embeddings: a first embedding associated with features present in a first modality, an intersection embedding associated with features present in both the first and a second modality, and an XOR embedding associated with features that are not shared between the first modality and the second modality. Once trained, the system may process a multimodal query image to determine query embedding data. Additional information, such as minutiae depicted in the multimodal query image may also be determined. The query embedding data, and in some implementations the additional information, may be compared with enrolled embedding data associated with a previously enrolled user. If the comparison exceeds a threshold value, an identity may be asserted.

Abstract: An air supply control arrangement for a heavy-duty vehicle including a lift axle which includes a brake chamber. The air supply control arrangement includes a valve configured to be arranged in an air supply passage that enables pressurized air to be supplied from a pressurized air source to a brake chamber of a lift axle of a heavy-duty vehicle; a processing circuitry configured to receive measurement values of the pressure inside a tire of the lift axle, wherein the processing circuitry is configured to, based on the received measurement values, determine whether the lift axle is in its raised lift condition or in its lowered ride condition, wherein the processing circuitry is configured to control the valve to move to a closed state upon determination that the lift axle has been raised from its ride condition to its lift condition, thereby preventing pressurized air from reaching the brake chamber.

Abstract: This disclosure describes a system for automatically updating item image information stored in an item images data store and used for processing captured images to identify items represented in those images. In one implementation, once an identity of an item has been verified, captured images of that item are associated with the item and stored in the item images data store. As a result, the item images data store is updated each time an image of the item is captured and the identity of the item is verified.

Abstract: An image of at least a portion of a user during enrollment to a biometric identification system is acquired and processed with a first model to determine a first embedding that is representative of features in that image in a first embedding space. The first embedding may be stored for later comparison to identify the user, while the image is not stored. A second model that uses a second embedding space may be later developed. A transformer is trained to accept as input an embedding from the first model and produce as output an embedding consistent with the second embedding space. The previously stored first embedding may be converted to a second embedding in a second embedding space using the transformer. As a result, new embedding models may be implemented without requiring storage of user images for later reprocessing with the new models or requiring re-enrollment by users.

Abstract: The motion of objects within a scene may be detected and tracked using digital (e.g., visual and depth) cameras aligned with fields of view that overlap at least in part. Objects may be identified within visual images captured from the scene using a tracking algorithm and correlated to point clouds or other depth models generated based on depth images captured from the scene. Once visual aspects (e.g., colors or other features) of objects are correlated to the point clouds, shapes and/or positions of the objects may be determined and used to further train the tracking algorithms to recognize the objects in subsequently captured frames. Moreover, a Kalman filter or other motion modeling technique may be used to enhance the prediction of a location of an object within subsequently captured frames.

Abstract: The invention relates to a method and ethernet physical layer device for detecting, classifying and localizing cable faults of an ethernet physical cable, particularly an automotive ethernet PHY, using a time domain reflectometry algorithm, using a hybrid mode for selectively subtracting sent signals from received signals for fault detection and classification and considering send and received signals during fault localization.

Abstract: A system and method for seamless resource sharing among web applications bundled into a software suite are disclosed. The present disclosure addresses the problem of manually downloading and uploading a resource from one web application to another web application inside a unified system, using Drag & Drop or Copy & Paste using a clipboard. One or more resources can be shared by a user from a source web application. The meta information of the resource is shared with a Resource Sharing Server, and the network resource of the user machine is not used in the download and upload process. The clipboard used in the Copy & Paste functionality facilitates pasting the content copied by users across multiple web applications, different sessions, and different devices. While sharing the resources, the permissions of the sender and receiver on the shared resource are used to filter the original resource using a permission filter and share only that which is permitted.

Abstract: An air supply control arrangement for a heavy-duty vehicle comprising a lift axle is provided. An electronically controlled brake valve device allows, when open, pressurized air to be passed to the brake chamber of the lift axle. A pressurized air source supplies pressurized air to the electronically controlled brake valve device along a supply passage. A pilot control valve provided between the pressurized air source and the electronically controlled brake valve device can restrict air flow through the supply passage. A pressure-responsive element actuates the pilot control valve when the pressure in the lift bellow is increased so that the lift axle is raised to a lift condition. The pressure-responsive element closes the pilot control valve. When the pressure in the lift bellow is reduced so that the lift axle is lowered to a ride condition then the pressure-responsive element is deactivated to allow opening of the pilot control valve.

Abstract: User enrollment to a biometric identification system begins with a pre-enrollment process on selected general input devices (GID) such as smartphones. The user may enter identification data such as their name and use a camera of the GID to acquire first image data, such as of their hand. The first image data is processed to determine a first representation. Upon presentation of a hand at a biometric input device, second image data is acquired. The second image data is processed to determine a second representation. If the second representation is deemed to be associated with the first representation, the enrollment process may be completed by storing the second representation for subsequent use.

Abstract: Described is a system and method for proactively determining and resolving events having low confidence scores and/or resolving disputed events. For example, when an event, such as a pick of an item from an inventory location within a materials handling facility occurs, the event aspects (e.g., user involved in the event, item involved in the event, action performed) are determined based on information provided from one or more input components (e.g., camera, weight sensor). If each event aspect cannot be determined with a high degree of confidence, the event information is provided to an associate for resolution.

Abstract: A system and method for fast save/restore is disclosed. The system and method include one or more logical units (LUs) residing in independent power domains, one or more digital frequency synthesizers (DFS), each of the one or more DFS associated with one of the one or more LUs, the one or more DFSs configured to lock a system complex frequency and ramp the one or more LUs to system complex frequency, and one or more slave fast save/restore control (FSRC) units, each slave FSRC unit associated with one of the one or more LUs, the one or more slave FSRC units configured to save/restore the FSRC states of the one or more LUs.

Abstract: Described is a system and method for presenting event information to a user and, if necessary, obtaining confirmation of different aspects (user, item, action) of the event. In some implementations, an event includes a user, an action, and an item. For example, an event may include a user picking an item from an inventory location, a user placing an item into a tote associated with the user, etc. if the aspects of the event cannot be determined with a high enough degree of confidence, a user interface may be generated and sent to the user requesting confirmation of one or more of the aspects of the event.

Abstract: This disclosure describes a system for automatically transitioning items from a materials handling facility without delaying a user as they exit the materials handling facility. For example, while a user is located in a materials handling facility, the user may pick one or more items. The items are identified and automatically associated with the user at or near the time of the item pick. When the users enters and/or passes through a transition area, the picked items are automatically transitioned to the user without affirmative input from or delay to the user.

Abstract: One example described herein includes a power switch control system. The system includes a first monitoring terminal coupled to a first terminal of a power transistor and a second monitoring terminal coupled to a second terminal of the power transistor. The power transistor and the power switch control system can form an ideal diode between the first monitoring terminal arranged as an anode and the second monitoring terminal arranged as a cathode. The system further includes a reverse current controller coupled to the first monitoring terminal and the second monitoring terminal and is configured to control activation of the power transistor to conduct a reverse current from the second monitoring terminal to the first monitoring terminal in response to a reverse voltage arranged as a cathode voltage at the second monitoring terminal being greater than an anode voltage at the first monitoring terminal.

Abstract: Described is a multiple-camera system and process for detecting, tracking, and re-verifying agents within a materials handling facility. In one implementation, a plurality of feature vectors may be generated for an agent and maintained as an agent model representative of the agent. When the object being tracked as the agent is to be re-verified, feature vectors representative of the object are generated and stored as a probe agent model. Feature vectors of the probe agent model are compared with corresponding feature vectors of candidate agent models for agents located in the materials handling facility. Based on the similarity scores, the agent may be re-verified, it may be determined that identifiers used for objects tracked as representative of the agents have been flipped, and/or to determine that tracking of the object representing the agent has been dropped.

Abstract: This disclosure describes a system for managing inventory as it transitions into a materials handling facility, as it transitions between locations within a materials handling facility and/or as it transitions out of a materials handling facility. In some instances, a user (e.g., picker or picking agent) may retrieve an item from an inventory location and place the item into a tote. The systems described herein detect the item when it is added to or removed from the tote.

Abstract: Where an event is determined to have occurred at a location within a vicinity of a plurality of actors, imaging data captured using cameras having the location is processed using one or more machine learning systems or techniques operating on the cameras to determine which of the actors is most likely associated with the event. For each relevant pixel of each image captured by a camera, the camera returns a set of vectors extending to pixels of body parts of actors who are most likely to have been involved with an event occurring at the relevant pixel, along with a measure of confidence in the respective vectors. A server receives the vectors from the cameras, determines which of the images depicted the event in a favorable view, based at least in part on the quality of such images, and selects one of the actors as associated with the event accordingly.
