Patent number: 10840833Abstract: A commutation circuit includes a coil connected to an H bridge, the H bridge including four main switches for reversing polarity and a resulting coil current in the coil. The commutation circuit further includes a voltage source configured to generate a bypass current, and at least one auxiliary switch for controlling the bypass current to thereby decrease a switch current through at least one of the main switches. By generating an appropriate bypass current with help of a voltage source, a switch current through a desired main switch in a leading state can be decreased and eventually brought to zero. Zero current in its turn enables the use of thyristors as main switches as it results in the thyristors to be turned off automatically. Furthermore, decreased switch current at the switching moment reduces switching losses even in different types of switches such as GTOs and IGBTs.Type: GrantFiled: March 31, 2015Date of Patent: November 17, 2020Assignee: ABB Schweiz AGInventors: Sjoerd Bosga, Veli-Matti Leppanen, Mehanathan Pathmanathan, Robert Chin, Yujing Liu

Patent number: 9811678Abstract: A method for encrypting data may generate an encryption instruction and combine it with a payload of data to form a packet. The packet is associated with a command and passed to a host file system process. The packet, now associated with a second command, is received from the host file system process. The encryption instruction and the payload of data are extracted from the packet. At least a portion of the payload of data is encrypted based on the encryption instruction. A method for decrypting data may receive a packet and generate a decryption instruction. At least a portion of the packet is decrypted using at least the decryption instruction. The second packet comprising the decrypted packet is passed to a host file system process. A third packet comprising the decrypted packet is received from the host file system process. The decrypted packet is extracted from the third packet.Type: GrantFiled: August 14, 2014Date of Patent: November 7, 2017Assignee: SanDisk Technologies LLCInventors: Haluk Kent Tanik, Robert Chin-Tse Chang, Po Yuan, Bahman Qawami, Farshid Sabet-Sharghi

Patent number: 8997214Abstract: In order to create and access a secure storage account in a non-volatile memory device, an account identification value is calculated. A memory identification value is read from a first non-volatile memory device. The memory identification value and the account identification value are transmitted to a second non-volatile memory device, and a calculated credential is received. A command is transmitted to create a secure storage account in the first non-volatile memory device, where the command contains the credential and the account identification value. To access the account, a sequence is transmitted, containing the account identification value and a value based on the credential. A secure storage system contains a first non-volatile memory device that stores a memory identification value and contains a secure partition accessible using a credential, a second non-volatile memory device that can compute the credential, and a host adapted to create and access the secure partition.Type: GrantFiled: February 21, 2012Date of Patent: March 31, 2015Assignee: SanDisk Technologies Inc.Inventors: Po Yuan, Javier Canis Robles, Mei Yan, Fabrice Jogand-Coulomb, Ahmet Altay, Bahman Qawami, Patricia Dwyer, Robert Chin-Tse Chang, Oktay Rasizade, Farshid Sabet-Sharghi

Patent number: 8590037Abstract: A method and system of controlling access to a hardware or software feature provided by a host is disclosed. An application seeking authorization to access a feature transmits a credential and an index to a host agent within the host. The index is associated with the requested feature. The host agent reads credential validation data from a storage location corresponding to the index in a non-volatile storage device in communication with the host. The validity of the credential is determined based on the credential validation data, and an authorization is transmitted if the credential is valid. A third party can control the outcome of the validity determination by sending an instruction to the host to replace the credential validation data with invalid data that causes the validity test to fail. The third party can also control the non-volatile storage device data used by the application to calculate the credential.Type: GrantFiled: December 23, 2008Date of Patent: November 19, 2013Assignee: SanDisk Technologies Inc.Inventors: Ahmet Altay, Haluk Kent Tanik, Robert Chin-Tse Chang, Xian Jun Liu, Oktay Rasizade, Po Yuan
