Patent number: 9807838Abstract: Systems and methods providing a downloadable custom light emitting diode (LED) blinking pattern for a controller, which performs backplane or enclosure management. The controller has a memory, which stores data of a standard LED blinking pattern. When no custom LED blinking pattern data is available in the memory, the controller controls the LEDs to perform a standard blinking pattern based on the standard LED blinking pattern data to indicate the of the storage drives. A user may generate a custom pattern file, which contains custom LED blinking pattern data, and then use a downloading tool to download the custom pattern file to the controller, such that the memory of the controller may store the custom LED blinking pattern data. Instead of using the standard LED blinking pattern, the controller may then control the LEDs to perform a custom blinking pattern based on the custom LED blinking pattern data.Type: GrantFiled: February 16, 2017Date of Patent: October 31, 2017Assignee: AMERICAN MEGATRENDS, INC.Inventors: Umasankar Mondal, Shibu Abraham

Patent number: 9363468Abstract: A vehicle display system and methods of controlling the same. In certain embodiments, an image processing module receives video signals from a video camera and generates first video data in a first format. A system management mode (SMM) program is stored in a memory. When executed at a processor, the SMM program reads the first video data from a first area of the memory, converts the first video data to second video data in a second format, and writes the second video data to a second area of the memory. A PCI express switch forwards the first video data in the first format to a memory controller for storing in the first area of the memory, and forwards the second video data in the second format from the second area of the memory to the graphic controller.Type: GrantFiled: February 19, 2014Date of Patent: June 7, 2016Assignee: AMERICAN MEGATRENDS, INC.Inventors: Umasankar Mondal, Jacob Narey, Roger Smith

Patent number: 8898349Abstract: Certain aspects direct to data transfer between a baseboard management controller (BMC) and a host computer. When the BMC is connected to the host computer via a universal serial bus (USB) interface, the BMC sends USB descriptors to the host computer such that the host computer recognizes the BMC as a specific human interface device (HID) device based on the USB descriptors. To transfer data to the host computer, the BMC converts the data to an Intelligent Platform Management Interface (IPMI) message, and generates a USB HID report containing the IPMI message as the report data. The BMC then sends the USB HID report to the host computer through the USB interface. When the BMC receives a USB HID report from the host computer, the BMC retrieves the report data, which is an IPMI message, from the USB HID report, and process the IPMI message to obtain the data.Type: GrantFiled: October 10, 2013Date of Patent: November 25, 2014Assignee: American Megatrends, Inc.Inventors: Umasankar Mondal, Jay Pancholi

Patent number: 7734953Abstract: Methods, systems, apparatus, and computer-readable media for providing a redundant power solution for an expansion card installed within a host computer. The expansion card has a hardware device and a power control mechanism. The power control mechanism provides power to the hardware device from a conditional power source when available, and from computer system standby power when the conditional power source is unavailable. The power control mechanism may comprise a power sensing mechanism to determine when conditional power source output decreases below a threshold level and a switching mechanism to switch from the conditional power source to computer system standby power when this happens. The hardware device may enter a low power mode upon receiving computer system standby power.Type: GrantFiled: June 12, 2006Date of Patent: June 8, 2010Assignee: American Megatrends, Inc.Inventors: Clas Gerhard Sivertsen, Umasankar Mondal

Patent number: 7167115Abstract: A method, apparatus, and computer-readable medium for compressing and decompressing an input data stream utilizing multiple dictionaries is provided. According the method for compressing data, a string and a character are read from the input data stream. A determination is made as to whether the string plus character are contained in a first or second dictionary. If the string plus character is in either dictionary, a next character is added to the string. If the string plus character is not in either dictionary, a code or character is output. A determination is then made as to whether the input word and string is a two character word. If so, a new code is added to the first dictionary corresponding to the two character word. Otherwise, a new code is added to the second dictionary for the string and character.Type: GrantFiled: August 26, 2005Date of Patent: January 23, 2007Assignee: American Megatrends, Inc.Inventors: Umasankar Mondal, Dingguo Zou
