Abstract: A pouch battery contains a pouch, an electrode material and a safety protection device. The electrode material is located in the pouch. The safety protection device is configured to generate an action based on a change in gas pressure within the pouch. In this way, even if the pouch battery is abnormal, its internal circuit can be cut off in time to avoid providing power to external devices while being under abnormal conditions.

Abstract: A charger adapted to charge either one of a first battery pack and a second battery pack. The first battery pack and the second battery pack have respectively a first interface and a second interface being substantially different from each other. The charger includes a housing having a receiving area in which the first battery pack and the second battery pack can be selectively received in such a way that the first battery pack is accommodated in a first region and the second battery pack is accommodated in a second region. The receiving area is at least partially defined by the first region partially overlapping the second region. The charger according to the invention is adapted to charge more than one type of battery pack, which saves cost and space needed for two separate chargers.

Abstract: A battery pack containing a frame; and two or more battery cells installed to the frame. The two or more battery cells are interconnected by a configurable connector which is configured to enable electrical connections between the two or more battery cells. The configurable connector is adapted to be configured in a first status or a second status. In the first status, the two or more battery cells are electrically connected, and in the second status, the two or more battery cells are not electrically connected. The battery pack is not fully operational without the terminal holder inserted, therefore before it is delivered to the end user the energy loss due to self-discharging during storage and shipping can be minimized.

Abstract: A system and a method for a grass maintenance comprising an autonomous vehicle (100) arranged to operate autonomously to manipulate a grass surface, wherein the vehicle (100) includes one or more environmental sensors (208) arranged to detect environmental conditions associated with the grass surface; and one or more grass manipulation modules (210) arranged to manipulate the grass surface.

Abstract: An electronic communication device for use in a navigation system. The electronic communication device comprises a first communication module arranged to communicate a first electromagnetic signal to at least one external communication device, wherein the at least one external communication device is operable to determine a physical distance between the respective external communication and the electronic communication device based on the first electromagnetic signal being received; a power module arranged to power the first communication module; and a mechanical structure arranged to at least temporally anchor the electronic communication device at a predetermined position.

Abstract: A docking station for use with an autonomous tool comprising a docking module for detachably receiving the autonomous tool and a guiding module arranged to guide the movement of the autonomous tool towards the docking module, wherein the autonomous tool, upon termination of the movement, is received by the docking module at a predetermined position and orientation.

Abstract: A printed circuit board assembly (PCBA) has a heat source, a heat sink, and an exit vent. The heat source generates heat, typically excessive heat and the heat sink conducts heat from the heat source and heats up the surrounding air to form heated air. The heated air then passes through the exit vent which is positioned adjacent to the heat sink. In addition, a heat dissipation structure contains a fan to move air, a heat source distal from the fan, an exit vent proximal to the fan, and an airflow path running from the heat source to the fan to the exit vent. The heat source heats the air to form heated air. When the fan is activated, the fan draws air through the airflow path from the heat source and out of the exit vent.
