  • Patent number: 11913930
    Abstract: A bismuth oxide material with a hierarchical structure in gas detection used for detecting the content of low-concentration ammonia in an environment. The bismuth oxide material with the hierarchical structure integrally presents a microsphere shape. The diameter of the microsphere is 1-3 ?m. The bismuth oxide material is formed by self-assembling lamellar structure units with the thickness of 10-80 nm. The bismuth oxide material is made into a gas sensor with high sensitivity and selectivity to ammonia gas at room temperature, which is suitable for detecting trace harmful gas in the environment. The gas sensor made of bismuth oxide does not need to be heated when in use, so that the heating step of the conventional gas sensor is omitted, and the gas sensor can be directly placed in a normal-temperature environment for operation. The method is simple, easy to operate, high in efficiency and wide in application prospect.

  • Patent number: 9125120
    Abstract: An apparatus supporting MTC in an LTE environment including an LTE modem and a CDMA modem. The LTE modem accesses a first wireless network and executes first data transactions, where the first wireless network comports with LTE standards. The CDMA modem is operationally coupled to the LTE modem, and accesses a second wireless network and executes second data transactions, where the second wireless network comports with one or more CDMA-based standards. The CDMA modem includes an inter-radio access technology (IRAT) API element and an inter-process communication (IPC) module. The IRAT API element is configured to send/receive IRAT messages via function calls to/from the LTE modem, where the IRAT messages remain the same regardless of interface requirements for the LTE modem. The IPC module is coupled to the IRAT API element, and is configured to generalize the function calls to enable the CDMA modem to interoperate with the LTE modem.
