Title: Methods and computer program products for encryption key generation and management
Inventor: YANG EN-HUI
IPC: H04L9/16
Filed: 2016-06-10
Granted: 2019-07-09
Abstract: The described embodiments relate to encryption methods and computer program products. An encryption application is used to determine a keystore seed with a seed bit set having seed bits in an ordered sequence. A plurality of key derivation sets are determined and a selected key derivation set is selected randomly. A key bit sequence is generated from the seed bit set using the selected key derivation set. An encryption key is generated using the key bit sequence, and corresponding keying information is determined from the selected key derivation set such that the latter is also derivable from the former. The keying information discloses zero information about the encryption key absent knowledge of the keystore seed. Plain text data is encrypted using the encryption key to generate cipher text data, and the keying information is stored with the cipher text data. The encryption key may then be deleted.

Abstract: Disclosed is an energy harvesting power-assist system and method for human powered light vehicles. The power-assist system comprises a drive mechanism, one or more motor/generators and a high capacity storage device. The system continuously harvests and stores energy which is converted to motion by the motors, providing additional power to the user's pedaling. A controller determines the amount of pedal assist based on a user's preset value, and manages the charge and discharge of the high capacity storage device. As such, the system does not require any other external energy source, and the storage device never needs external charging under the described usage cases.

Title: Control of hydraulic power flowrate for managed pressure drilling
Inventor: NORTHAM PAUL R
IPC: E21B21/08
Filed: 2017-01-24
Granted: 2020-04-28
Abstract: An assembly uses a choke to control flow of wellbore fluid in a drilling system. A controller operatively coupled to the choke can control opening/closing of the choke with hydraulic power and an actuator. The control operates the opening/closing of the choke with a choke control value to control a parameter in the drilling system, such as pressure or flow. The control measure a time for the choke to at least reach a position toward a full open/closed position during a full opening/closing operation and calculates a current opening/closing speed of the choke. When this current speed is compared to a previously stored speed, the control adjusts the choke control value for the choke based on any difference.
