Abstract: A data system is provided for analyzing and maintaining data obtained from one or more data sources on which the data system depends. The system includes a primary database including current values used by the system and a collection of executable algorithms used to generate the data maintained in the primary database. In response to receiving a notification regarding a change in one of the data sources, a dependency database is used to establish an execution order for algorithms of the algorithm collection that are directly or indirectly dependent on the changed data. The algorithms identified in the execution order are then executed in accordance with the execution order and the corresponding result is stored in the primary database. The system may include data harvesters adapted to recognize changes in the data sources and to generate and transmit corresponding change notifications when such changes occur.

Abstract: A work-assist device includes a chest-support member configured to support a user's chest when the user is using the work-assist device. The work-assist device also includes a knee-support member configured to support the user's knees when the user is using the work-assist device. The knee-support member includes a pad having a curved lower surface and configured to cause the work-assist device to rock forward or backward in response to a weight shift by the user when the user is using the work-assist device. The work-assist device further includes an elongate frame member that includes a first end and a second end, where the first end is attached to the knee support member and the second end is attached to the chest support member. The work-assist device is configured to fully support the user in a forward-biased position when the user is using the work-assist device.

Abstract: An apparatus is disclosed for simultaneously measuring the rotational speed and/or direction of a shaft, and providing control power in accordance with the shaft rotation. The apparatus includes a permanent magnet machine (PMM) having a multipole rotor and a stator. The rotor has a plurality of permanent magnet poles and connection to the rotating shaft; the stator includes a winding and electrical connections, so that motion of the rotor with respect to the stator causes a voltage signal at the electrical connections. The apparatus also includes a circuit including a power conversion portion and a speed/direction sensing portion. The circuit receives the voltage signal from the PMM, and simultaneously outputs control power from the power conversion portion and a signal indicating the rotational speed and/or direction of the shaft from the sensing portion.
