Abstract: A robotic assistant comprises a plurality of sensors on a mobile chassis. An occupancy map includes obstacle cost values for particular areas or cells of the map. These obstacle cost values may be based on whether an obstacle is detected and the confidence value of that detection, estimated precision of the location of the detected object, and so forth. A set of rules for preferred locations of robot movement is used to assess the occupancy map and to determine constraint cost value for the particular areas. For example, the area in a center of a hallway may be associated with a relatively high constraint cost value. An aggregate cost value may be calculated by summing the obstacle cost value and the constraint cost value for the particular area. The aggregate cost value may be used to determine a maximum permissible speed for the robot while traversing the particular area.

Abstract: Sensors in a facility obtain sensor data about a user's interaction with a fixture, such as a shelf. The sensor data may include images such as obtained from overhead cameras, weight changes from weight sensors at the shelf, and so forth. Based on the sensor data, one or more hypotheses that indicate the items and quantity may be determined and assessed. The hypotheses may be based on information such as the location of a user and where their hands are, weight changes, physical layout data indicative of where items are stowed, cart data indicative of what items are in the possession of the user, and so forth. A hypothesis having a greatest confidence value may be deemed to be representative of the user's interaction, and interaction data indicative of the item and quantity may be stored.

Abstract: The present disclosure relates to pretreating a magnetic recording head for magnetic media drive. For a heat assisted magnetic recording (HAMR) head, a light source provides the necessary heat for the drive to operation. A vertical cavity surface emitting laser (VCSEL) is mounted to a top surface of a slider. A plurality of laser beams are emitted from the bottom surface of the VCSEL and directed to a corresponding number of waveguide structures within the HAMR head. The waveguide structures feed into a multimode interference (MMI) device that then directs the laser into a single waveguide for focusing on a near field transducer (NFT). The VCSEL lasers are phase coherent and have no mode hopping.

Abstract: Provided herein are techniques for rescuing a commercial transaction identified as suspect, possibly based on suspicion of fraud or due to the risk associated with the commercial transaction.

Abstract: Systems for facilitating the return of items include generating first code data associated with an order and second code data associated with an item within the order. When input data indicating the first code data is received, user interface data presenting the items associated with the order is generated. The user interface may be customized to prioritize primary characteristics of items, such as size or color of clothing items, and may be arranged to position items more likely to be returned prior to other items based on a user's previous activity. When input data indicative of the second code data is received, a return process for the item associated with the second code data is initiated. User interface data indicating the return of the item is then generated and presented. Use of code data to initiate returns may reduce the need for a user to navigate a user interface.

Abstract: Hygiene regulations and social distancing are very effective in blocking short distance infections. During the lockdown, the distance rules can usually be adhered to, but what happens when the actual lockdown is over, and the people meet again in a confined space? Then additional effective and efficient protection is essential to stabilize infection rates. Since the viruses are spread by contact and droplet infection, technical devices are required that effectively intervene in the chain of infection and effectively block infection. An effective protection is the respiratory mask as known since 100 years. This patent application discloses an alternative to mask that is an aerosol protection helmet (APH) for various applications in the environment. The aerosol protection helmet consists of adjustable air sucking and blowing devices in different form factors based on the application. The aerosol protection helmet protects against any aerosol in the environment.

Abstract: A controller utilizes dual sense bin balancing (DSBB) to adjust a read level between memory states of an array of NAND flash memory cells. One or more iterations of DSBB may be performed to provide a read level. Each iteration of the DSBB includes performing a first sense read, performing a second sense read, determining a read error, and adjusting the initial read level. The first sense read is performed at a first offset of an initial read level of memory cells. The second sense read is performed at a second offset of the initial read level of memory cells. A read error is determined from the first sense read and the second sense read. The read level is adjusted by the read error. A read of the randomized data pattern is conducted with the adjusted read level of a last iteration of the DSBB.
