Abstract: A two-piece wheel may have a first section and a second section. The wheel has areas of varying diameter across its width, and the first section and second section are joined at the area of the wheel with the smallest diameter. The first section can be a spoke section with spokes extending from a central hub and the second section can be a barrel section.

Abstract: The present disclosure provides a two (2) piece wheel comprising a first section and a second section wherein the wheel comprises areas of varying diameter across its width and the first section and second section are joined at the area of the wheel with the smallest diameter.

Abstract: A system, method and computer readable medium comprising instructions for sending a message from an Optical Network Terminal (ONT) to an Optical Line Terminal (OLT), if the ONT does not receive an expected OLT action or an expected OLT response to the message within a period, considering the non-receipt of the expected OLT action or the expected OLT response a failure, and if a certain number of consecutive failures have occurred, considering by the ONT that it has entered an uncontrolled state.

Abstract: A high voltage cell or battery has its voltage reduced for lower voltage applications by means of volt lowering diodes i.e. p-n junction and resistive elements placed in series with the cells and the appliance to be electrically powered.

Abstract: A metal-air battery usually comprises a plurality of air-depolarizable cells within a battery case. The present invention provides that the battery case has a vent and a vent cover, where the vent cover is associated with an electrical actuator so as to open only when the battery is supplying electrical power to a load. In this manner, the metal-air battery is open to the atmosphere only when it is operating, and consequently is open to the possibility of harsh ambient conditions such as very high or very low ambient relative humidity, prolonged carbon dioxide exposure, and so on; and as a consequence, a long operating life for the battery which operates only intermittently during that life can be expected.
