Abstract: A system can be configured to receive and analyze an image captured by a user device at a delivery location. The system can utilize local algorithms tailored to the delivery location to confirm that the delivery location is the intended delivery location for a package. The system can utilize global algorithms to generate three-dimensional models of the delivery environment and an augmented reality interface providing delivery instructions to the deliverer. The delivery instructions include indications of approved delivery locations and rejected delivery locations associated with the general delivery location of the customer.

Abstract: A service may be provided that reads sensors, and that communicates information based on the sensor readings to applications. In one example, an operating system provides a sensor interface that allows programs that run on a machine to read the values of sensors (such as an accelerometer, light meter, etc.). A service may use the interface to read the value of sensors, and may receive subscriptions to sensor values from other programs. The service may then generate messages that contain the sensor value, and may provide these messages to programs that have subscribed to the messages. The messages may contain raw sensor data. Or, the messages may contain information that is derived from the sensor data and/or from other data.

Abstract: The disclosure relates to mixed analog-digital circuits, and more specifically a low-noise millimeter-wave fractional-N frequency synthesizer. It overcomes quantization noise and fractional spurs caused by the limited dynamic range and nonlinearity of time error amplifiers (TA) in traditional phase-locked loop structures based on TA. In addition to the traditional structure, the synthesizer includes a coarse digital-to-time converter (CDTC), a fine digital-to-time converter (FDTC), and DTC non-linearity calibration circuits. By inserting the CDTC and FDTC before and after the TA, respectively, the variance of the input phase difference of the TA can be reduced, thereby improving the TA linearity and suppressing the quantization noise and spur generated by fractional-N operation. Furthermore, by using non-linearity calibration, the non-linearity of DTC and TA can be compensated to avoid large quantization noise and spur while the second order quantization noise reshaping is maintained.

Abstract: The present disclosure provides a two-dimensional motor combination piston pump by combining two independent two-dimensional piston pumps into one structure to achieve parallel outputting. The combination piston pump includes a two-dimensional motor and a two-dimensional piston pump. The outer rotator serves as the piston and the flow distribution mechanism of the two-dimensional piston pump. While operating, outer rotator rotates and moves axially.

Abstract: The present invention discloses a calculation method of eddy current loss in magnetic materials based on magnetic-inductance. The present invention proposes a vector model of a magnetic circuit, an eddy current reaction is equivalent to a magnetic-inductance component in the magnetic circuit, and the eddy current loss can be fast calculated by the vector model of the magnetic circuit. When the frequency is high, the eddy current loss dominates an iron loss and can be estimated as an entire iron loss. The present invention proposes the vector model of the magnetic circuit based on which the calculation method of eddy current loss in magnetic materials is proposed as well. Through the proposed method the eddy current loss in magnetic materials can be directly calculated by using the magnetic-inductance and the magnetic flux in the magnetic circuit, which can provide guidance for design and performance evaluation of high-frequency electrical equipment from a brand new viewpoint.
