  • Patent number: 10092226
    Abstract: A mechanism for non-invasively monitoring blood characteristics of a subject is disclosed. To enable measurement of hemoglobin concentrations in a cost-effective way, a computational model is established that represents a relationship between a first variable indicative of total hemoglobin concentration and a set of variables that includes second variables indicative of light transmission through tissue and third variables indicative of concentration percentages of different hemoglobin species. In-vivo measurement signals are acquired from a subject and in-vivo values are determined for the second and third variables based on the in-vivo measurement signals. The first variable is then solved based on the in-vivo values of the second and third variables and the computational model.

  • Patent number: 10088516
    Abstract: Embodiments of the disclosure relate to detecting turn-to-turn faults in one or more windings of various objects. In one implementation, a fault detector uses a differential protection algorithm to detect a turn-to-turn fault in a winding of a three-phase shunt reactor. Various voltage and current measurements carried out upon the three-phase shunt reactor are used to calculate a difference value between a voltage-based parameter and a current-based parameter. The voltage-based parameter is indicative of a normalized negative voltage imbalance and the current-based parameter is indicative of a normalized negative current imbalance. A turn-to-turn winding fault is declared when the difference value is not equal to zero.

  • Patent number: 10088658
    Abstract: Referencing of image acquired in multiple rounds of imaging is disclosed. In certain implementations, a baseline round of images are acquired and registered to one another to establish a global transformation matrix. In a subsequent round of image acquisition, a limited number of field of view images are initially acquired and registered to the corresponding baseline images to solve for translation, rotation, and scale. The full set of baseline images is then acquired for the subsequent round and each image is pre-rotated and pre-scaled based on the transform determined for the subset of images. The pre-rotated, pre-scaled images are then registered using a translation-only transform.

  • Patent number: 10089083
    Abstract: Provided are a system and method for generating a service broker code for a service deployed on a cloud platform. In one example, the method includes generating service broker code for the service in which the generated service broker code includes built-in code that supports a plurality of operations of the service broker built and one or more gaps in the code corresponding to one or more operations of the service broker not supported by the built-in code thereby enabling customization of the service broker. The method further includes transmitting the generated service broker code to a user device associated with the service for filling in code for the one or more operations. Because gaps are left in the generated service broker code, the service broker can be customized by a developer of the service while incorporating already built-in code that has been tested and verified.
