Abstract: A combustion system configured to receive fuel from a plurality of fuel sources, wherein the combustion system includes a burner, a shutter, a fuel selector, and an electronic controller configured to receive an indication of a selected fuel type from the fuel selector and output instructions for the shutter to adjust to a shutter position associated with the selected fuel type, the shutter position being configured to provide a predetermined supply of air to thereby effect an air-to-fuel ratio associated with combustion of the selected fuel type.

Abstract: The disclosed technology includes a leak detection system for a fluid heating device, the leak detection system including: a structure configured to at least partially insert into a portion of a fluid heater; a fluid removing portion of or in contact with the structure, the fluid removing portion configured to transport water from the structure to at least one leak sensor; and the at least one leak sensor configured to detect the fluid transported from the structure by the fluid removing portion.

Abstract: A battery-powered device, especially a hand-held, data collection terminal having an electro-optical scanner, includes a main housing, a battery pack separate from the main housing, and a latching mechanism for latching the battery pack in its assembled position on the main housing in which it is partially received in a correspondingly configured receiving recess of the main housing. Electrical circuitry in the device is shut down prior to battery pack removal. During idle periods, the device is supported on a cradle, with a back or handle portion of the device being received in a main compartment of the cradle. The cradle also includes an auxiliary compartment for receiving the battery pack for recharging the same.

Abstract: A battery-powered device (10), especially a hand-held, data collection terminal having an electro-optical scanner, includes a housing (11), a battery pack (12) separate from the housing (11), and a latching mechanism (18) for latching the battery pack (12) in its assembled position on the housing (11) in which it is partially received in a receiving recess (17) of the housing (11). The mechanism (18) includes a slidable latching member (19) with a portion (33) for engaging the recess (17) in the battery pack (12) and a locking button (20) that is transversely movable into position to retain the latching member (19) in its recess engaging position. Electrical circuitry in the device is shut down prior to battery pack removal by movement of the locking button (20) to effect release of the latching member (19) and to operate a power shut-down switch (34). In another embodiment, a battery compartment door (112) is used to operate a shut-down switch (134).
