Abstract: An electric machine includes a stator and a rotor energizable by magnetic fields produced by the stator when receiving a stator current to produce relative motion between the rotor and the stator. A controller is configured to send the stator current through the stator at a current angle measured from the closest one of a pole of the rotor, determine a desired operational output of the electric machine, and determine a desired rotor motion corresponding to the desired operational output of the electric machine. The controller is further configured to calculate a vector control modulation applied to the stator that elicits the desired rotor motion, and adjust the current angle of the stator current based on the vector control modulation to cause the rotor to perform the desired rotor motion and achieve the desired operational output of the electric machine.

Abstract: A method for securing a split private key (such as used with a cryptocurrency or other non-custodial electronic wallet) amongst a password, biometrics, and a social service. The process may use a sharding scheme such as Shamir's Secret Sharing to ensure that multiple key shards must be obtained before the entire private key can be obtained. The user may select the number of shards required to retrieve the private key thereby controlling the security of the account. An additional shard may be held on an encrypted server and allows for account recovery even while maintaining non-custodial ownership of the wallet.

Abstract: A wall hanging inventory control and packaging system comprises a wall bracket secured on a wall and provided with a rail at a top lip of the wall bracket at a side near the wall; and at least one carrier, each of which comprises a body for accommodating an article or articles and a hook or clip member extending from the body and engaging with the rail so that the at least one carrier may slide along the wall bracket. The wall hanging inventory control and packaging system according to the present invention is able to efficiently use over the floor or ground space and avoid occupying floor or ground space, and each carrier is capable of being placed anywhere along or sliding on the wall bracket so that it is more convenient to organize and take out an article(s) as needed and help reduce time for finding and taking out items by the end-user.
