  • Patent number: 10929019
    Abstract: Data storage facilities that provide data storage services are typically arranged as either individually accessible drive facilities or multi-carrier drive facilities, but both types must contend with hardware failures that require storage device (e.g., drives) to be replaced. Multi-carrier drive facilities generally have greatly increased drive density, but are confronted with challenges with respect to service operations that are not present for facilities with individually accessible drives. For example, replacing a faulted storage device can entail bringing the faulted storage device as well as other (e.g., non-faulted) storage devices offline during the service operation, which can impact the data storage services. Techniques that improve service for multi-carrier drive facilities are presented. Such techniques can improve coordination between elements that manage the storage facility and those that provide service to faulted storage elements.

  • Patent number: 10321664
    Abstract: An apparatus or a method for detecting activity quantity of an object includes a sense unit, a count unit, a trigger unit, and a radio circuit. The sense unit senses movements of the object, and generates a sensing signal based on the sensed movements. The count unit receives the sensing signal from the sense unit, counts a number of the movements from the sensing signal, and generates a movement number signal including the number of the movements. The trigger unit generates a trigger signal based on whether one or more trigger conditions are satisfied. The radio circuit is triggered in response to the trigger signal, to generate an activity quantity signal based on the movement number signal and ID information corresponding to the object.

  • Patent number: 10275618
    Abstract: A system and method of selectively reading sensor data from a memory device is able to search the memory device for an indicator that identifies the sensor data, and read only the sensor data identified by the indicator from the memory device. In this way, interrogating devices are able to sort through sensor data stored in a network of memory devices, such as an RFID network, and report specific data of interest despite the existence of a variety of data types in the network. In some embodiments, flags are stored and associated with specific types of data, such as various sensor data, thereby allowing numerous memory devices and sensors to operate and be read efficiently in the same environment.

  • Patent number: 10271733
    Abstract: Bubbles (118-122) are utilized in some embodiments as part of a photoacoustic contrast agent (162) and, in some embodiments, to localize one or more locations (126-38) of a source of acoustic energy. The bubbles, such as microbubbles, can be used in proximity of nanoparticles of a first photoacoustic contrast agent, thereby affording a second photoacoustic contrast agent. The bubbles can intercept and re-radiate acoustic energy emitted by light-based activation of the first photoacoustic contrast agent in the immediate vicinity of the bubbles. As a further option, if the nanoparticles permeate further to tissue structures but remain in close enough proximity, their positions can be triangulated by the nearby bubbles, based on direction (144-148) and time delays (150-160) of ultrasound received by a transducer array.

  • Patent number: 10207591
    Abstract: The mobile vehicle charging system is applied to a mobile vehicle and includes a docking platform and a charging device. The docking platform provides parking to the mobile vehicle. The charging device includes an electricity transmission interface and an electricity measurement module. When the mobile vehicle is parked on the docking platform, the electricity transmission interface charges a battery module through an electricity reception interface of the mobile vehicle. As such, when an operator of the mobile vehicle parks the mobile vehicle onto the docking platform, the mobile vehicle can be automatically charged by the mobile vehicle charging system.

  • Patent number: 10192087
    Abstract: In some arrangements, product packaging is digitally watermarked over most of its extent to facilitate high-throughput item identification at retail checkouts. Imagery captured by conventional or plenoptic cameras can be processed (e.g., by GPUs) to derive several different perspective-transformed views—further minimizing the need to manually reposition items for identification. Crinkles and other deformations in product packaging can be optically sensed, allowing such surfaces to be virtually flattened to aid identification. Piles of items can be 3D-modelled and virtually segmented into geometric primitives to aid identification, and to discover locations of obscured items. Other data (e.g., including data from sensors in aisles, shelves and carts, and gaze tracking for clues about visual saliency) can be used in assessing identification hypotheses about an item. A great variety of other features and arrangements are also detailed.

  • Patent number: 10149177
    Abstract: A wireless sensor includes an antenna structure, an RF signal circuit, a sensing element, memory and a processing module. In a calibration mode, the sensing element is exposed to a known condition and causes a first change of an operating characteristic of the antenna structure while receiving the RF signal. The processing module generates a first digital value based on the first change and writes it into the memory. In a sense mode, the sensing element is exposed to an unknown condition and causes a second change of an operating characteristic of the antenna structure while receiving the RF signal. The processing module generates a second digital value based on the second change and writes it into the memory.
