Abstract: A battery is provided with an associated method for transporting metal-ions in the battery using a low temperature molten salt (LTMS). The battery comprises an anode, a cathode formed from a LTMS having a liquid phase at a temperature of less than 150° C., a current collector submerged in the LTMS, and a metal-ion permeable separator interposed between the LTMS and the anode. The method transports metal-ions from the separator to the current collector in response to the LTMS acting simultaneously as a cathode and an electrolyte. More explicitly, metal-ions are transported from the separator to the current collector by creating a liquid flow of LTMS interacting with the current collector and separator.

Abstract: A low overhead voice activity detection technique for a noise-canceling bioacoustic sensor consumes, as inputs, signals generated by a body microphone and an environment microphone and produces, as an output based on these inputs, an indication of whether voice activity is present. The technique applies a novel dual ANC configuration that produces, in addition to the normal noise reduction function, a signal composed of environmental sounds with body sounds attenuated and a signal composed of body sounds projected into the acoustic environment, primarily speech sounds. The technique then applies to these derived signals an algorithm based on the scientific observation that speech intensity, within limits, rises and falls to match environmental sound intensity to provide voice activity detection.

Abstract: A method is provided for cycling power in a transition metal cyanometallate (TMCM) cathode battery. The method provides a battery with a TMCM cathode, an anode, and an electrolyte, where TMCM corresponds to the chemical formula of AXM1NM2M(CN)Y-d(H2O), where “A” is an alkali or alkaline earth metal, and where M1 and M2 are transition metals.

In response to discharging the battery, the “A” metal plating is removed from the anode plating surface. In one aspect, in an initial charging of the battery, a permanent solid electrolyte interphase (SEI) layer is formed overlying the anode plating surface. In subsequent charging and discharging cycles, the permanent SEI layer is maintained overlying the anode plating surface.

Abstract: A sensor calibration method and system dynamically compute a bias offset which is subtracted from field strength readings generated by a sensor to correct them. The three-dimensional space around a sensor is seeded with orientation targets. As the sensor is rotated to different orientations, field strength readings are generated by the sensor and assigned to different targets based on estimated proximity. Once occupancy of targets conforms to a first state of occupancy, a coarse bias offset is computed for the sensor using readings from occupied targets. Once occupancy of targets conforms to a second state of occupancy, a refined bias offset is computed for the sensor using readings from occupied targets. Multiple sensors may be calibrated concurrently. Moreover, a user interface provides a real-time graphic showing the location and occupancy status of individual targets and highlighting the individual target best aligned with a most recent corrected sensor reading.
