Patent number: 8228038Abstract: A power management system includes a sensor to detect current output from a battery, a first comparator to compare the battery current to a first reference value, and a burst controller to perform a first power control operation based on said comparison. The power control operation reduces power consumed by the battery in order to cause the battery current to fall below the first reference value. This may be accomplished by reducing or shutting down power to one or more functions or features of a host system that includes or is coupled to receive power from the battery. The host system may include or correspond to a mobile phone and/or any of a number of other electronic devices.Type: GrantFiled: December 23, 2009Date of Patent: July 24, 2012Assignee: Intel CorporationInventors: Kevin R. Mullen, Kuriappan P. Alappat, Don J. Nguyen

Patent number: 7340538Abstract: A method for dynamic assignment of slot-dependent static network port addresses. Under the method, a slot address and shelf address are determined for a card modular platform board installed in a given slot in a shelf. The slot and shelf addresses are used as inputs to return a unique network address. The unique network address is then assigned as a static network address for the board's network port. The unique address may be provided by an address proxy, including a boot server. Firmware and/or software stored on a board may also be employed to obtain the static network address. The address may be obtained from a pre-configured lookup table, or dynamically determined using an algorithm.Type: GrantFiled: December 3, 2003Date of Patent: March 4, 2008Assignee: Intel CorporationInventors: Kuriappan P. Alappat, Chetan Hiremath

Patent number: 7152418Abstract: A method and apparatus to manage airflow in a chassis includes one or more airflow restrictor assemblies disposed adjacent a slot within the chassis. The airflow restrictor assemblies can be set in a plurality of positions between a minimum airflow position and a maximum airflow position. The position of the airflow restrictor assembly can be set in accordance with characteristics of the module inserted in the slot. The module characteristics may include power dissipation and airflow resistance.Type: GrantFiled: July 6, 2004Date of Patent: December 26, 2006Assignee: Intel CorporationInventors: Kuriappan P.

Patent number: 6876102Abstract: Disclosed are a system and method of detecting a diode fault among diodes coupled to a plurality of redundant power feeds. A diode short fault may be detected by measuring a first voltage across a first one of the diodes, measuring a second voltage between two nodes including a terminal of the first diode and detecting the diode short based upon the first and second voltages. A diode open fault may be detected by decoupling a first one of the diodes from a power feed and measuring the voltage across the diode.Type: GrantFiled: July 24, 2002Date of Patent: April 5, 2005Assignee: Intel CorporationInventor: Kuriappan P.

Patent number: 5440676Abstract: An analog input signal to a digital oscilloscope is sampled and digitized to form a representative waveform data sequence. A waveform is then displayed on a screen of the oscilloscope to represent the magnitude of the waveform as a function of time as indicated by the waveform data sequence. The waveform is formed by a set of vectors, each vector comprising a straight line between two points on the screen at elevations representing magnitudes of two successive input signal samples, and at horizontal positions representing timing of the two samples. The screen provides a display organized into an array of pixels, each of which may be illuminated with variable intensity, and each vector is represented by illuminating pixels having center points bounding the trajectory of the vector on the screen. The intensity of each such illuminated pixel is modulated in accordance with the distance between the pixel and the vector trajectory.Type: GrantFiled: January 29, 1988Date of Patent: August 8, 1995Assignee: Tektronix, Inc.Inventors: Kuriappan P. Alappat, Edward E. Ayerill, James G. Larsen

Patent number: 5387896Abstract: Apparatus for manipulating numerical values stored in a memory comprises a modify device for receiving numerical values from the memory and returning numerical values to the memory. The modify device has at least a first state in which it modifies a numerical value received from the memory in a predetermined fashion before returning the numerical value to the memory and a second state in which it does not modify a numerical value received from the memory in the predetermined fashion before returning the numerical value to the memory. The apparatus also comprises a characterizing device for examining at least some of the numerical values and calculating at least one number that defines a property of the examined numerical values. The characterizing device is connected to the modify device for placing the modify device in the first state or the second state depending on the value of the calculated number.Type: GrantFiled: August 6, 1990Date of Patent: February 7, 1995Assignee: Tektronix, Inc.Inventors: Kuriappan P.
