Abstract: Various arrangements for detecting an object using a passive infrared (PIR) sensor module of a sensor device. A PIR data stream may be received from the PIR sensor module indicative of measurements performed by the PIR sensor module. An indication may be received from a transceiver that identifies a beginning of the data transmission. A portion of the PIR data stream may be blanked in response to receiving the indication of the beginning of the data transmission, the portion of the PIR data stream corresponding to a defined time duration. A presence of an object may be determined using the PIR data stream, excluding the blanked portion.

Abstract: A method for recovering reforming catalyst comprises obtaining spent reforming catalysts; immersing the spent reforming catalysts with different degrees of aging into a light solution to obtain immersed catalysts and allowing the light solution to enter pores in the spent reforming catalysts to lower a pseudo-skeletal density of each spent reforming catalyst to obtain immersed catalysts; immersing the immersed catalysts into a heavy solution that has a density greater than pseudo-skeletal density of the immersed catalysts and replacing the light solution in the pores in the immersed catalysts by the heavy solution to increase density of the immersed catalysts; and awaiting the immersed catalysts to settle in the heavy solution to obtain settled catalysts, wherein different settling velocities due to aging creates layers of settled catalysts. Therefore, the reforming catalysts with different degrees of aging are easily classified into different layers, which can be reused for cost saving.
