Abstract: Zen Roller is manufactured to our exact specifications so the Himalayan salt barrel does not break during machining or use. The other two pieces (a surgical steel clasp, and a handle) are designed to hold the barrel while allowing for rotation—and for easy removal and/or replacement. In addition, the outer surface of the Himalayan salt barrel is highly polished to our exact specifications so it is non-abrasive to the skin.

Abstract: Implementations of a system for sensing rotor position of a PMSM may include: a controller which may be coupled with the PMSM. The controller may be configured to apply a plurality of voltage vectors to the PMSM to generate a plurality of sensing signals from a stator of the PMSM in response. A comparator may be coupled to the PMSM configured to receive and to compare each one of the plurality of sensing signals with a threshold voltage. A rise time measurement circuit may calculate a plurality of rise times using the plurality of sensing signals in response to receiving a signal from the comparator. The rotor-angle estimation circuit may be configured to identify from the plurality of rise times a shortest rise time and a voltage vector corresponding with the shortest rise time and thereby identify the position of the rotor of the PMSM.

Abstract: An apparatus and method for aligning two coaxially coupled rotatable shafts. A servo operated multi axis positioning device is movable along a longitudinal axis parallel to the axis of the shafts, and movable vertically to position a laser range (LRF) adjacent to the two shafts, which measures the distance between the LRF and a spot on the shafts. A controller having a processor and memory communicates with the positioning device and the LRF to collect data at two axial positions on each shaft. At each position the LRF measures the distance to the shaft and stores the measurement and location data. The LRF is vertically repositioned and the measurement and storing steps are repeated over a scan distance sufficient to provide enough data to determine the location of the shaft center. The processor then calculates and compares the shafts centerlines and determines the necessary adjustments needed to move the shafts into coaxial alignment.

Abstract: Technology is disclosed herein for a spacecraft launch restraint and dispensing structure. The dispensing structure has a number of trusses and a central structure. When the trusses are in a support position, each spacecraft may be supported at one point by the central structure and at two points by one or more of the trusses. Therefore, each spacecraft may be supported at three points, thereby providing a stable support for each spacecraft. The spacecrafts do not touch each other and do not bear the weight of other spacecrafts. In a deployment position, the trusses extend away from the satellites and do not support the satellites; however, the satellites initially remain connected to the central structure. In the deployment position, the trusses are out of an ejection path such that the satellites can be ejected in a desired sequence from the central structure.
