Latest Patents

One of Spencer's latest patents is titled "Multivariate predictive insulation resistance measurement." This invention involves a process where a plurality of capacitors undergoes a test cycle of charging, soaking, and discharging. During the soaking cycle, multiple measurements of current are obtained. The collected data is then utilized to train a predictive function. Subsequently, a test capacitor is charged and soaked for a shorter duration than the other capacitors. The current through the test capacitor is measured multiple times during its soak period, and these measured current values are applied to the predictive function. This process predicts whether the current through the test capacitor at the end of the soak time period would exceed a predetermined value, indicating a potential failure in the leakage test.

Another significant patent is "Testing and sorting system having a linear track and method of using the same." This invention presents an improved method and apparatus for testing and sorting electro-optic devices based on both electrical and optical properties at high speed. In this system, electro-optic devices, particularly light-emitting diodes, are singulated by a device and transferred to a linear track for testing. The devices are then sorted into various bins according to their tested properties.
