Abstract: A digital filtering method includes receiving a digital signal, and passing the digital signal through a Pth order comb cascade. The method includes beginning pre-computing of intermediate integrator states of a Pth order integrator cascade as a function of the digital signal, prior to receiving output from a last comb of the Pth order comb cascade. The outputs from each comb of the Pth order comb cascade are then applied to the pre-computed intermediate integrator states to thereby produce a filtered version of the digital signal. The Pth order comb cascade may operate at a sampling frequency, and the pre-computing of the intermediate integrator states is performed at the sampling frequency, while the application of the outputs from each comb of the Pth order comb cascade to the pre-computed intermediate integrator states is performed at a multiple of the sampling frequency.

Abstract: Schedules are generated that satisfy the objectives of a field services provider given a set of resources and a set of work orders. More particularly, work orders are identified, as well as the identity of resources that are capable with fulfilling one or more of the work orders, are obtained. Feasible paths are established for each resource that identify a sequence of one or more work orders that can be fulfilled by the resource over the course of the resource's work shift and which reflect one or more scheduling objectives. These feasible paths are established in a series of iterations, with each iteration identifying additional paths. After each iteration, it is determined if a pre-selected time limit has been exceeded, and whenever the time limit has been exceeded, path generation ceases. Schedules are established for the resources using the generated paths and are then provided to the field service provider.

Abstract: A novel anode for a lithium battery cell is provided. The anode contains silicon nanoparticles embedded in a solid polymer electrolyte. The electrolyte can also act as a binder for the silicon nanoparticles. A plurality of voids is dispersed throughout the solid polymer electrolyte. The anode may also contain electronically conductive carbon particles. Upon charging of the cell, the silicon nanoparticles expand as take up lithium ions. The solid polymer electrolyte can deform reversibly in response to the expansion of the nanoparticles and transfer the volume expansion to the voids.

Abstract: Variety of approaches to optimize a meeting based on an organizer rating are described. A productivity service initiates operations to optimize a meeting by transmitting a request to a meeting attended to rate a meeting organizer for an evaluation of a usefulness of a meeting. A usefulness value associated with the meeting is received from the meeting attendee. A meeting score is computed from the usefulness value. The meeting score is stored in an association with the meeting organizer.

Abstract: The accurate determination of the state-of-charge (SOC) of batteries is an important element of battery management. One method to determine SOC is to measure the voltage of the cell and exploiting the correlation between voltage and SOC. For electrodes with sloped charge/discharge profiles, this is a good method. However, for batteries with lithium iron phosphate (LFP) cathodes the charge/discharge profile is flat. Now, by using the materials and methods disclosed herein, an amount of cathode active material that has a sloped charge/discharge profile is mixed with LFP in a cathode, which results in a charge/discharge profile with enough slope that the SOC of the battery can be determined by measuring the voltage alone.

Abstract: A sulfur-based cathode for use in an electrochemical cell is disclosed. The sulfur is sequestered to the cathode to enhance cycle lifetime for the cathode and the cell. An exemplary sulfur-based cathode is coupled with a solid polymer electrolyte instead of a conventional liquid electrolyte. The dry, solid polymer electrolyte further acts as a diffusion barrier for the sulfur. Together with a sequestering matrix in the cathode, the solid polymer electrolyte prevents sulfur capacity fade that occurs in conventional liquid electrolyte based sulfur systems. The sequestering polymer in the cathode further binds the sulfur-containing active particles, preventing sulfur agglomerates from forming, while still allowing lithium ions to be transported between the anode and cathode.

Abstract: An optimal architecture for a polymer electrolyte battery, wherein one or more layers of electrolyte (e.g., solid block-copolymer) are situated between two electrodes, is disclosed. An anolyte layer, adjacent the anode, is chosen to be chemically and electrochemically stable against the anode active material. A catholyte layer, adjacent the cathode, is chosen to be chemically and electrochemically stable against the cathode active material.
