Patent number: 11347290Abstract: Power monitor information in an information handling system may be adjusted based on a battery voltage to account for a battery discharge state. The power monitor information may be scaled higher when the battery voltage is low to encourage the system to throttle and decrease power consumption. This adjustment increases the likelihood that the battery remains within safe operating limits.Type: GrantFiled: August 4, 2017Date of Patent: May 31, 2022Assignee: DELL PRODUCTS L.P.Inventors: Mohammed Hijazi, Merle J. Wood, III, Christian L. Critz, Chin-Jui Liu

Patent number: 10802560Abstract: An information handling system with multiple power input ports, such as USB ports, capable of receiving power from external power supplies may control power received from the power supplies. A first controller may detect a first power supply coupled to a first power input port of the system and may allow power to flow from the external power supply to the system. Any additional power supplies detected by controllers may be blocked from providing power to the system while the first power supply is providing power.Type: GrantFiled: April 20, 2018Date of Patent: October 13, 2020Assignee: Dell Products L.P.Inventors: Mohammed Hijazi, Geroncio O. Tan, Merle J. Wood, III, Marcin Nowak

Patent number: 10795421Abstract: An external device and an information handling system may be attached through a single port connection to provide bi-directional transfer or data and power through the port connection. The port connector may allow the information handling system to function as both a power source and a power sink. This allows the information handling system to provide power to certain external devices from an internal battery to avoid data corruption when power to an external device is unexpectedly lost. When AC power is restored to the external device, the information handling system may be reconfigured to not transmit power to the external device and to receive power from the external device to operate the information handling system.Type: GrantFiled: August 4, 2017Date of Patent: October 6, 2020Assignee: Dell Products L.P.Inventors: Mohammed Hijazi, Merle J. Wood, III, Marcin Nowak

Patent number: 10680432Abstract: Redundancy in over-voltage fault protection may be provided by controlling switches already present in a power path of a port for an information handling system. An external device coupled to a port may be decoupled from the system when an over-voltage condition is detected at another port of the information handling system. To decouple an external device upon detection of an over-voltage condition, a switch coupled to the port and the external device is turned off. A battery may also be decoupled from a port upon detection of an over-voltage condition at another port.Type: GrantFiled: August 4, 2017Date of Patent: June 9, 2020Assignee: Dell Products L.P.Inventors: Mohammed Hijazi, Merle J.

Patent number: 10539990Abstract: An information handling system may have multiple batteries and be powered by any one or combination of those batteries. The multiple batteries may be in different detachable portions of the system. When the portions are attached, a battery in one unit connects through multiple input paths to provide power to the other unit. Under a heavy loading condition, power may be drawn from a first battery while power from a second battery is routed to an external power input of the information handling system to supplement power drawn from the first battery.Type: GrantFiled: August 4, 2017Date of Patent: January 21, 2020Assignee: Dell Products L.P.Inventors: Geroncio O.

Publication number: 20190044436Abstract: A multi-path capacitor divider circuit may select an input path for a capacitor divider based on a number of cells of a battery. The capacitor divider may then divide a voltage of power received from the battery based on the selected input path and may output power at a lower voltage as a result of the division. The capacitor divider may be coupled to the battery through a battery receptacle capable of receiving batteries of different configurations and different numbers of cells. The lower voltage output of the capacitor divider may be used by a high-frequency voltage regulator.Type: ApplicationFiled: August 4, 2017Publication date: February 7, 2019Applicant: Dell Products L.P.Inventors: Mohammed Hijazi, Merle J.

Patent number: 7471061Abstract: A technique is disclosed for more fully utilizing the full voltage range of a battery driven battery output voltage when the battery output voltage is provided through voltage regulation circuitry. More particularly, when the battery output voltage drops to a level that is insufficient to support the desired output of the voltage regulation circuitry, the battery output voltage may be coupled to the voltage output in a manner bypassing at least a portion of the voltage regulation circuitry. In this manner additional voltage range of the battery output voltage may be utilized while still maintaining an output voltage within a desired output voltage range. In one embodiment, such a technique may be utilized in an uninterruptible power supply system.Type: GrantFiled: March 21, 2006Date of Patent: December 30, 2008Assignee: Dell Products L.P.Inventors: Shreya M.

Publication number: 20070086105Abstract: An entertainment system includes an optical media drive operable to playback contents of an optical media and a storage device (SD) to store data. The SD includes a head to read and write the data, a detector input to detect the playback of the optical media and a control output to move the head in a predefined motion in response to the playback. The predefined motion, which occurs continuously at a predefined constant speed, prevents the SD from generating an unsolicited sound during the playback, thereby improving the multimedia experience. The predefined motion is disabled when the playback is disabled.Type: ApplicationFiled: October 14, 2005Publication date: April 19, 2007Applicant: Dell Products L.P.Inventors: Sek Ng, Mohammed Hijazi
