Publication number: 20240073003Abstract: A method of data transfer from a tenant to a service provider comprises encrypting the data with a public key of a key pair generated by a secure device within the service provider system. The data thus cannot be accessed by the service provider during transmission. The data is generated with a corresponding access control list, which specifies that a valid certificate must be presented in order to grant a particular use of the data once stored. The tenant can thus retain control of the use of the data even though it has been transferred out of the tenant system. A method of controlling use of data securely stored in the service provider system comprises issuing a use certificate having an expiry time to the party requesting use of the data. The use certificate must be validated before use of the stored data is granted. This enables the tenant to grant use of the stored data for a limited time period.Type: ApplicationFiled: November 8, 2023Publication date: February 29, 2024Applicant: NCIPHER SECURITY LIMITEDInventors: Ian BYGRAVE, Alec EDGINGTON, Richard KETTLEWELL, David O'DOHERTY, Nicholas SMITH, Neil WALKER

Publication number: 20230109403Abstract: A phased-array includes, in part, N transceivers each including a receiver and a transmitter, and a controller. The phased array is configured to transmit a first radio signal from a first element of the array during a first time period, receive the first radio signal from a second element of the array, recover a first value associated with the radio signal received by the second element, transmit a second radio signal from the second element of the array during a second time period, receive the second radio signal from the first element of the array, recover a second value associated with the radio signal received by the first element, and determine a first phase of a reference signal received by the second element from the recovered first and second values. The first phase is relative to a second phase of the reference signal received by the first element.Type: ApplicationFiled: February 28, 2022Publication date: April 6, 2023Inventors: Austin C.

Publication number: 20190330267Abstract: The present invention relates to improved processes for purifying polypeptides of interest by increasing the amount of a polypeptide of interest bound to an ion-exchange matrix relative to the amount of one or more impurities bound to the ion-exchange matrix. This effect is achieved by adding a chemical compound in the process which by also binding to the ion-exchange matrix due to a change that is opposite to the change of the ion-exchange matrix, reduces the binding of impurities more than the binding of the polypeptide of interest.Type: ApplicationFiled: June 28, 2019Publication date: October 31, 2019Applicant: CSL LimitedInventors: Adam Charlton, Mark Napoli, Paul Smrdelj, Anthony Stowers, Vicky Pirzas, Magnus Schroeder, Ian Walker
