As per the limitation a power interface to enable a connection of the portable fire alarm with an external Direct Current (DC) power source to supply power to the sensing unit. Du discloses, in ¶32, the concept of providing a DC input interface to enable connection of a DC power source with a portable emergency sensing and warning device. At the time of filing, it would have been obvious to a person of ordinary skill in the art to incorporate the concept of providing a DC input interface to enable connection of a DC power source with a portable emergency sensing and warning device, with the motivation to enhance power supply features of the system. As per the limitation the alert generation unit to generate the alert (Jarosz: Col. 2, lines 21-43; also see Lee page 4); and an internal DC power source configured to supply power to the sensing unit (Jarosz: claim 1) and the alert generation unit to generate the alert (Jarosz: claim 1). As per the limitation an interface mole configured to establish a connection with a communication mole of another device to send the generated alert to one or more external electronic devices. Du discloses, on page 4, the concept of providing a communication means to enable generated alarm notifications to be transmitted to an external smartphone. At the time of filing, it would have been obvious to a person of ordinary skill in the art to incorporate the concept of providing a communication means to enable generated alarm notifications to be transmitted to an external smartphone, with the motivation to enhance alarm notification features of the system. 2) Regarding claim 2 and 10, wherein the at least one of the one or more on-board sensors and the one or more remotely located sensor devices comprise at least one of a temperature sensor (Lee: page 4 with regard to the heat sensor), a gas sensor (Lee: page 4), a smoke sensor (Jarosz: Col. 2, lines 21-57; Lee: page 4), and a flame sensor (Lee: page 4 with regard to the illumination sensor 15). 3) Regarding claims 3 and 11, wherein the sensor-related data indicates at least one of a change in temperature, a detection of flame, a detection of a target gas (Lee: page 4), or a detection of smoke in the environment (Jarosz: Col. 2, lines 21-57; Lee: page 4). 4) Regarding claims 4 and 12, wherein the alert generation unit is configured to compare the at least one of the change in the temperature (Lee: page 6), the detection of flame (Lee: page 6), the detection of the target gas (Lee: page 4 with regard to the detection of combustion gas), or the detection of smoke in the environment with a corresponding predefined criteria to determine whether the received sensor-data corresponds to the potential fire hazard (Jarosz: Col. 2, line 44 through Col. 3, line 17; Lee pages 5-6). 5) Regarding claims 5 and 13, wherein the alert corresponds to at least one of an activation of one or more visual indicators, an activation of a sound signal, or a combination thereof (Jarosz: Col. 2, line 44 through Col. 3, line 17; Lee pages 4-6). 6) Regarding claims 6 and 14, wherein the external DC power source comprises a battery powered device (Du: ¶18, with regard to the cigar lighter interface can be directly connected to the vehicle, hence connected to an external device powered by a battery).
