Regarding claim 5, Hall discloses an accelerometer, the antenna configured to transmit data associated with an output of the accelerometer (col. 7, lines 1-13). Regarding claim 9, Hall discloses a power source 44 secured to the housing, the output of the power source controlled responsive to the output of the accelerometer. Regarding claim 11, Hall (modified by Kenny) discloses all the claimed subject matter as set forth above in the rejection of claim 1, but does not disclose the antenna being configured to transmit an identifier associated with the housing. Kenney teaches the use of an antenna being configured to transmit an identifier associated with a housing (col. 11, lines 8-35). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include the antenna being configured to transmit an identifier associated with the housing to the system of Hall as taught by Kenney for the purpose of effectively identifying different housings. Regarding claim 12, Hall discloses wherein the housing covers the location sensor, the acetone vapor sensor and the alarm such that they can't be seen (figure 1). Regarding claim 14, Hall (modified by Kenny) discloses all the claimed subject matter as set forth above in the rejection of claim 1, and further discloses an arrangement comprising a plurality of detection units 10, 10’, each comprising one or more processors 152; wherein the memory has stored therein a plurality of instructions that when read by the one or more processors cause the one or more processors to: receive data from each of the plurality of detection units (col. 9, lines 24-52), responsive to the received data, determine a model of normal parameters for any, or a combination, of location sensors, acetone vapor sensors, temperature sensors, humidity sensors and/or accelerometers, and output the determined model (col. 9, line 53-col 10, line 33). Claim(s) 4 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hall and Kenney as applied to claim 1 above, and further in view of Eisenstadt (US 2015/0192475). Regarding claim 4, Hall (modified by Kenny) discloses all the claimed subject matter as set forth above in the rejection of claim 1, but does not disclose a humidity sensor with an output of the humidity sensor. Eisenstadt teaches the use of a humidity sensor with an output of the humidity sensor (paragraph 35). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to include a humidity sensor with an output of the humidity sensor to the system of Hall (modified by Kenny) as taught by Eisenstadt for the purpose of effectively monitoring humidity in an enclosure. Claim(s) 6-8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hall and Kenney as applied to claim 5 above, and further in view of Goldberg (US 2021/0217111). Regarding claims 6 and 7, Hall (modified by Kenny) discloses all the claimed subject matter as set forth above in the rejection of claim 5, and further discloses one or more processors 42; and a memory (col. 10, lines 18-28, col. 11, lines 38-50), the memory having stored therein a plurality of instructions that when executed by the one or more processors cause the one or more processors to determine, responsive to the output of the accelerometer (col 7, lines 1-13), but does not disclose the one or more processors to determine in what type of vehicle the housing is being transported, and output information associated with the determined type of vehicle (claim 6); a condition of a road that the housing is being transported on, and output information associated with the determined condition of the road (claim 7). Goldberg teaches the use of one or more processors to determine in what type of vehicle a housing is being transported, and output information associated with the determined type of vehicle (paragraph 87); a condition of a road that the housing is being transported on, and output information associated with the determined condition of the road (p. 87).
