Abstract: An apparatus for power conversion includes a switching network that controls interconnections between pump capacitors in a capacitor network that has a terminal coupled to a current source, and a charge-management subsystem. In operation, the switching network causes the capacitor network to execute charge-pump operating cycles during each of which the capacitor network adopts different configurations in response to different configurations of the switching network. At the start of a first charge-pump operating cycle, each pump capacitor assumes a corresponding initial state. The charge-management subsystem restores each pump capacitor to the initial state by the start of a second charge-pump operating cycle that follows the first charge-pump operating cycle.

Abstract: Systems for ultrasonic measurements of an inspection surface is described. An inspection robot with a payload moves in a direction of travel across an inspection surface. The payload has two sensor holders, the first sensor holder to hold a first UT array at a first orientation and the second to hold a second UT array at a second orientation A sensor holder linking component holds the two UT phased arrays in a parallel configuration along their long edges. An arm of the payload may be pivotably connected to both the sensor linking component at one end and a lift connection element on the other end. The lift component has a lift motor to raise the lift connection element. A rastering device moves the payload in a direction of inspection which is distinct from both the direction of travel and the parallel configuration of the two phased UT arrays.

The inspection robot may include a payload including a first ultrasonic (UT) phased array and a second UT phased array, the first UT phased array and the second UT phased array being arranged in a parallel configuration. The inspection robot may include a rastering device structured to move the payload in a direction of inspection, the direction of inspection being distinct from the direction of travel and the direction of inspection being distinct from the parallel configuration of the first UT phased array and the second UT phased array.

Abstract: Provided are systems and methods for predicting a travel range of a vehicle. The method comprises receiving, using at least one processor, travel information associated with the vehicle, receiving, using the at least one processor, a weather forecast and a traffic forecast associated with the travel information, and predicting, using the at least one processor, the predicted travel range based at least in part on a battery charge level of the vehicle, the weather forecast, and the traffic forecast. In embodiments, the predicted travel range may be based on current and historical battery charge levels, current and/or historical battery discharge rates, weather forecast data, and traffic forecast data.

Abstract: An apparatus for converting a first voltage into a second voltage includes a reconfigurable switched capacitor power converter having a selectable conversion gain. The power converter has switch elements configured to electrically interconnect capacitors to one another and/or to the first or second voltage in successive states. The switch elements are configured to interconnect at least some capacitors to one another through the switch elements. A controller causes the reconfigurable switched capacitor power converter to transition between first and second operation modes. The controller minimizes electrical transients arising from transition between modes. In the first operating mode, the power converter operates with a first conversion gain. In the second operating mode, it operates with a second conversion gain.

Abstract: A computer implemented method for distributing, collecting and monitoring assignments by a content management system. The method includes receiving a request for a file request from a teacher to distribute an assignment to one or more students. In response to receiving the request, the teacher is prompted for information associated with the assignment. The information can include a name for the assignment, an assignment file and a collection identifier. In response to receiving the information, one or more metadata tags are generated based on the received information. The file request is distributed along with the one or more metadata tags to the one or more student.

Abstract: Methods, systems, and devices for secure transaction management are provided. Embodiments include a method for providing secure transactions that include receiving an identifier of a financial account at a payment processor system. A token may be generated that is linked with the identifier of the financial account at the payment processor system. The identifier of the financial account and the token may be stored securely at the payment processor system. The token may be transmitted without the identifier of the financial account to at least a recipient system or a recipient device where the token replaces the identifier of the financial account.

Abstract: A spring contact for a coaxial connector includes a first ring provided with a plurality of spring fingers extending toward a connector end of the first ring and a second ring provided with a plurality of spring fingers extending toward a connector end of the second ring. The first ring and the second ring are nested together. The spring contact may be manufactured, for example, by stamping a pre-form ring from a planar metal sheet and then bending the spring fingers extending radially inward from an inner diameter of the pre-form ring to extend towards a connector end of the resulting spring contact.

Abstract: A stabilizing coupling body assembly for a coaxial connector is provided with a coupling body dimensioned to couple at a connector end of the coupling body with a cable end of the connector. A jacket grip of rigid material is retained between the coupling body and a stabilizing body coupled to a cable end of the coupling body. An outer diameter of the jacket grip abuts an annular wedge surface of the stabilizing body. The wedge surface is provided with a taper between a maximum diameter proximate a connector end of the jacket grip and a minimum diameter proximate a cable end of the annular wedge surface. The jacket grip is driven radially inward as the stabilizing body is advanced axially towards the coupling body. Methods of manufacture include forming elements of the coupling body assembly via injection molding.
