Method for detecting extended range motion and counting moving objects using an acoustics microphone array

An acoustic array platform comprising multiple spaced microphones and associated processing electronics / algorithms projects distinct beams in a chosen look direction across which moving objects such as vehicles pass. These moving objects are accurately detected, classified and counted at extended ranges. The acoustic microphone array employs optimized beamforming to create specially focused listening directions that function as a “motion detector” and “trip line counter”. Algorithms detect and confirm the appropriate presence of objects moving through the beams and perform other algorithmic tests to verify that the object is a valid object to be counted. The proposed approach is realized with modest sized acoustic arrays and a reasonable number of microphones by employing an adaptive beamforming algorithm that achieves enhanced directivity in a principal look direction and which significantly reduces the effects of interferers outside the precise steering direction of the “trip line”.

Integrated self-powered tire revolution counter

A self-powered tire revolution counter includes a motion sensitive power generation mechanism, a power conditioner, a pulse detector, a microcontroller, and, optionally, a radio frequency (RF) transmitting device. In one exemplary embodiment, the power generation mechanism corresponds to a piezoelectric patch that, during movement, provides both operating electrical power and pulsed signals indicative of tire rotation. The power conditioner receives a generator signal from the power generation mechanism and produces a conditioned output voltage that can be used to power associated electronic devices, including the microcontroller. The pulse detector receives the generator signal and produces a detection signal whenever the generator signal meets a predetermined condition. The microcontroller is programmed to determine current and lifetime-accumulated values of selected pulse indications in the detection signal that meet predetermined criteria. Data corresponding to tire environment related parameters such as temperature, pressure, tire deflection, and / or vehicle speed may be stored in the microcontroller at times during tire rotation as power is supplied from the power generation mechanism through the power conditioner. Additional data may be supplied to the microcontroller directly from an external source and read from the microcontroller either by direct electrical contact or via selective RF transmission.

Phase subtraction cell counting method

A method and device are provided for counting cells in a sample of living tissue, such as an embryo. The method involves obtaining a microscopic image of the unstained tissue that reveals cell boundaries, such as a differential interference contrast (DIC) image, and an optical quadrature microscopy (OQM) image which is used to prepare an image of optical path length deviation (OPD) across the cell cluster. The boundaries of individual cells in the cell cluster are modeled as ellipses and used, together with the maximum optical path length deviation of a cell, to calculate ellipsoidal model cells that are subtracted from the OPD image. The process is repeated until the OPD image is depleted of phase signal attributable to cells of the cell cluster, and the cell count is obtained from the number of cells subtracted. The method is capable of accurately and non-invasively counting the number of cells in a living embryo at the 2-30 cell stage, and can be employed to assess the developmental stage and health of human embryos for fertility treatments.
