Title: Systems and methods for rotor position determination
Inventor: YE JIN
IPC: H02P23/14
Filed: 2015-04-01
Abstract: Various embodiments are described herein for a system and method to eliminate mutual flux effect on rotor position estimation of switched reluctance motor (SRM) drives at rotating shaft conditions without a prior knowledge of mutual flux. Neglecting the magnetic saturation, the operation of conventional self-inductance estimation using phase current slope difference method can be classified into three modes: Mode I, ll and III. At positive-current-slope and negative-current-slope sampling point of one phase, the sign of current slope of the other phase changes in Mode I and II, but does not change in Mode III. In one example embodiment, in order to operate the self-inductance estimation in Mode III, a variable-hysteresis-band current control method is proposed for the incoming phase and variable-sampling method is proposed for the outgoing phase.

Title: Travel headrest device with flexible tethers, detachable multi-axis joints and permanent swivel mounting option
Inventor: SAMPSON DANIEL
IPC: A47C16/00
Filed: 2015-10-22
Abstract: A portable headrest device suitable for use in travel situations features an elongated main support, a headrest for carrying on the elongated main support in an elevated position above a support surface, a base plate for placement on the support surface to stabilize the elongated main support in the upright operational position, and a respective multi-axis joint between the elongated main support and each of the headrest and the base plate.

Title: Method and system for controlling a hydrocracker and fractionator
Inventor: REDELMEIER ROBERT JAMES
IPC: C10G7/12
Filed: 2014-07-24
Abstract: A method and system for controlling a hydrocracker and fractionator reaction loop is disclosed. The method and system utilizes a sidedraw tray within the fractionator distillation zone upon which liquid is collected. This liquid is withdrawn as a sidedraw stream. The withdrawal of the liquid from the sidedraw tray is controlled based on the level of liquid on the sidedraw tray rather than at a set or determined flow rate. The sidedraw stream is separated into a first stream and a product stream. Unlike other processes where the flow rate of the product stream is set and the internal reflux flow rate varies, the method involves fixing the flow rate of the first stream that is returned to the distillation zone of the fractionators with the flow rate of the product stream being set so as to control the liquid level on the sidedraw tray.
