Abstract: A system includes an auxiliary battery configured to be disposed onboard a vehicle having an electrically powered propulsion system that is configured to also be powered by detachable main batteries, and a converter configured to be electrically coupled with the auxiliary battery and the propulsion system of the vehicle. The converter is configured to direct electric energy stored in the auxiliary battery to the propulsion system for powering the propulsion system while the vehicle is detached from a depleted detachable main battery and before the vehicle is connected with a charged detachable main battery.

Abstract: Authentication of a computing device involves displaying a plurality of subareas on a touchscreen display of a computing device, detecting a touch contact in a first subarea of the plurality of subareas, detecting a first swipe gesture from the first subarea to a second subarea of the plurality of subareas, detecting a first confirmation gesture associated with the first swipe gesture, and authenticating the computing device based at least in part on the first swipe gesture.

Abstract: Authentication of a computing device involves displaying an authentication code display area and an authentication code input area on a touchscreen display of a computing device, detecting a touch contact at a first touch point in the authentication code input area, presenting a first character associated with the first touch point on the display, detecting a first swipe gesture from the first touch point to a second touch point, presenting a second character associated with the second touch point, detecting a confirmation gesture associated with the second touch point, and authenticating the computing device based at least in part on the second character.

Abstract: In accordance with embodiments of the present disclosure, an information handling system may include a communications bus, at least one target device communicatively coupled to the communications bus, and a plurality of master devices communicatively coupled to the communications bus and communicatively coupled to one another via a secondary arbitration connection. Each of the plurality of master devices may be configured to assert a respective secondary arbitration signal of the master device on the secondary arbitration connection to indicate ownership of the communications bus and deassert the respective secondary arbitration signal of the master device on the secondary arbitration connection to indicate non-ownership of the communications bus.

Abstract: A hard drive carrier includes a frame to receive a hard drive. The frame includes a front and a side, and a handle connects to the front. The hard drive carrier engages with a hard drive bay to hold the hard drive carrier in the hard drive bay at a first insertion depth when the handle is in a closed position. The first insertion depth is selected to prevent a hard drive connector from engaging with an enclosure connector on a backplane of the hard drive bay. The hard drive carrier further engages with the hard drive bay to hold the hard drive carrier at a second insertion depth when the handle is in the closed position. The second insertion depth is selected to engage the hard drive connector with the enclosure connector.

Abstract: A power over Ethernet (PoE) compliant device may be able to keep alive just enough of a management controller and/or target to respond to requests and tell a host (initiator) why it may be unable to respond to a data transfer request in a desired fashion due to a power failure. Thus only a small portion of an information handling system management capabilities need stay alive for reporting the operational condition of the overall information handling system during a power outage.

Abstract: A system and method for providing a communication enabled UPS power system for information handling system is disclosed. According to one aspect, an information handling system can be used to communicate with a power source using a first power cable. The information handling system can include a power circuit operable to power a portion of an information handling system using input power provided by an uninterruptible power supply (UPS). The information handling system can also include a UPS controller coupled to the power circuit. The UPS controller can control the output of the first UPS using a first power cable operable to provide the input power to power the portion of the information handling system.

Abstract: An intelligent hotspare drive with pre-emptive drive rebuild is disclosed. In accordance with one embodiment of the present disclosure, a method for rebuilding a drive using an intelligent hotspare drive in an information handling system including detecting an error in a first drive in an information handling system such that the error indicates a possible drive failure. The method further includes automatically rebuilding the first drive with the detected problem using a second drive in the information handling system such that the second drive begins to mirror the first drive even though the first drive has not failed.

Abstract: A system and method for identifying physical blocks marked as logically “bad” or “punctured” during a drive rebuild process enabling the information handling system to process these blocks more intelligently and preventing existing drive physical media errors from needlessly being copied and propagated to new drives. Various implementations of the invention allow physical blocks on a target drive to be marked as “punctured” so they can be diagnosed to verify that they have not been erroneously marked as being “bad,” thereby reducing the number of misdiagnosed drive failures.
