Abstract: Methods, systems, and devices for worker ranking, worker scheduling, and enterprise labor sharing are described. A method includes: receiving objective evaluation data associated with members of a workforce; receiving subjective evaluation data associated with the members; generating composite evaluation data associated with the first members based on the objective evaluation data, the subjective evaluation data, or both; and generating scheduling information associated with the members based on the composite evaluation data. Another method includes: assigning members of a workforce to candidate temporal periods of a work schedule, where the assigning is based on a priority order corresponding to composite evaluation data associated with the members.

Abstract: An apparatus and method for automatically handling vest-type bags in the context of an automated packing process for packing items such as groceries are described. The apparatus includes at least two fingers that extend parallel to one another, and are arranged to move apart to increase the spacing between the fingers along a bag-opening direction. The fingers are inserted between the strips of the handle, and then moved apart in the bag-opening direction to part the strips of the handle in the bag-opening direction. A packing process involving automated bag handling operations is also inclosed.

Abstract: A method and receiver are disclosed for mitigating or substantially canceling signal interference between signals detected at the receiver. Once a presumed interfering signal(s) is acquired, parameters are determined that allow the interferer(s) to be modeled. The phase invariance of the process eliminates the need to acquire the interferer's phase. An orthogonal projection (for projecting onto a detection subspace which is orthogonal to a subspace spanned by the interferer(s)) is applied to the composite of all signals (y) for thereby projecting y onto the detection subspace. The interference subspace is non-orthogonal to a representation of desired (but interfered) signal of the composite signals. With the receiver properly equipped to perform this projection operation, interfering signals, multipath, multipath-like, and structured jamming signals can be effectively diminished.

Abstract: The present invention provides systems and methods for decreasing interference in a selected coded signal. The system includes a matrix generator for generating a matrix. The matrix may comprise vectors, the elements of which are formed from components of the interference. The interference may exist in the form of co-channel and/or cross channel interference, such as that found in CDMA telephony. The components of this interference may, therefore, be code components of the interference that are used to fill elements of the vectors. Each element of a vector may represent a code component of an interfering coded signal. A processor uses the matrix to substantially remove the interference from the selected coded signal. For example, the processor may generate a projection operator that projects the coded signal substantially orthogonal to the interference such that the impact of interference on the selected coded signal is substantially reduced.

Abstract: The architecture of the present invention is premised upon an algorithm involving integration of oblique correlators and RAKE filtering to null interference from other spread spectrum signals. The oblique correlator is based on the non-orthogonal projections that are optimum for nulling structured signals such as spread spectrum signals. In one configuration, space spanned by a first signal associated with a first emitter is orthogonal to an interference space associated with one or more signals of one or more other emitters. RAKE filtering is used to rapidly steer the beam of the multi-antenna system and to mitigate the effects of multipath.
