  • Publication number: 20210310987
    Abstract: There is provided a nanopore sensor including cis and trans fluidic reservoirs. A nanopore is provided in a support structure separating the cis and trans reservoirs. The nanopore has an inlet in fluidic connection with the cis fluidic reservoir and an outlet in fluidic connection with the trans fluidic reservoir. The cis fluidic reservoir has a fluidic access resistance, RC, the trans fluidic reservoir has a fluidic access resistance, RT, and the nanopore has a fluidic resistance, RP. RP is of the same order of magnitude as RT and both RP and RT are at least an order of magnitude greater than RC. An electrical transduction element is disposed at a nanopore sensor site that exposes the transduction element to the trans reservoir. An electrical circuit is connected to the electrical transduction element for producing an electrical signal indicative of changes in electrical potential local to the trans reservoir.

  • Patent number: 11067534
    Abstract: There is provided a multi-channel nanopore sensor having a plurality of independent nanopore sensors. Each independent nanopore sensor includes a nanopore disposed in a support structure. A fluidic connection is between a first fluidic reservoir, common to all of the independent nanopore sensors, and an inlet to the nanopore, with a first ionic solution of a first ionic concentration disposed in the first fluidic reservoir. A fluidic connection is between a second fluidic reservoir, common to all of the independent nanopore sensors, and an outlet from the nanopore, with a second ionic solution of a second ionic concentration, different than the first ionic concentration, disposed in the second fluidic reservoir. An electrical transduction element, disposed in contact with that ionic solution having a lower ionic concentration, is arranged at a site that produces an electrical signal indicative of electrical potential local to that ionic solution having a lower ionic concentration.

  • Patent number: 11061623
    Abstract: Storage virtualization techniques allow files and directories to be stored remotely, for example, by a cloud storage provider, but in a manner that appears to a user or application running on a local computing device as if the files are stored locally—even though the data of those files and directories may not be resident on the local computing device. That is, the contents of files and directories that may exist in the cloud look and behave as if they were stored locally on a computing device. The level of hydration of placeholders may be monitored and operations may be performed to reduce the impact of excessive hydration on the resources of the computing device.

  • Patent number: 10929350
    Abstract: A system to enable a user to generate copies of files at a client device and to cause a file hosting platform to generate backups of these copies in a cloud database without transferring file content data for these files between the client device and the cloud database. When a user copies a file from a first folder on a client device to a second folder on the client device, the system may determine that the file content data for this file is already present in the cloud database. Then, rather than uploading the file content data to the cloud database from the client device, the system may cause a file hosting platform to access the file content data directly from the cloud database to perform a file copy operation.

  • Publication number: 20200400649
    Abstract: A first fluidic solution having a first ionic concentration is provided in a first fluidic reservoir in direct fluidic connection with a nanopore. A second fluidic solution, having a second ionic concentration, is provided in a second fluidic reservoir disposed in fluidic connection with the nanopore through a fluidic passage having at least one fluidic section in which the section length is greater than the section width. The electrical potential local to the fluidic passage is measured, and the resistance of both the fluidic passage the nanopore are determined based on the fluidic passage electrical potential. The fluidic passage resistance is compared with the nanopore resistance and at least one of the first and second ionic concentrations is adjusted based on the comparison. The measuring, determining, comparing, and adjusting steps are conducted until the fluidic passage resistance is between about 0.1 times and about 10 times the nanopore resistance.

  • Publication number: 20200400648
    Abstract: In a method for sensing translocation of a molecule through a nanopore, a molecule in a first fluidic solution in a first fluidic reservoir that is in direct fluidic connection with the nanopore is directed to a nanopore inlet and translocated through the nanopore to a nanopore outlet and through a fluidic passage that is in direct fluidic connection with the nanopore outlet, to a second fluidic solution in a second fluidic reservoir disposed in direct fluidic connection with the fluidic passage. The fluidic passage has at least one fluidic section in which a length of the fluidic section is greater than a width of the fluidic section. Translocation of the molecule through the nanopore is sensed by measuring the electrical potential local to the fluidic passage during the translocation of the molecule.

  • Patent number: 10795747
    Abstract: Systems, methods, and apparatuses are disclosed for file synchronizing service status monitoring and error handling. A client device includes a local file system access manager that includes a status interface. The status interface is configured to receive a status message from a client-side sync manager of the client device. The client-side sync manager that communicates with a server-side sync manager at a server to synchronize data objects between file systems of the client device and server. The status message corresponds to a state of the client-side sync manager during a multi-stage start-up process for the client-side sync manager. A status caller in an application of the client device can retrieve the status message from the status interface. The status message can also be provided to a user interface for display to a user of the client device, and/or to a telemetry server for use in improving the file synchronizing service.
