Patent number: 8542031Abstract: Disclosed is a circuit for adjusting a voltage supplied to an IC by a power supply circuit that produces a regulated-output voltage based on an output-control signal generated by a resistive voltage divider. The circuit includes a PVT detector configured to generate an interface control signal and an interface circuit (i) connected to PVT detector and to the resistive voltage divider and (ii) configured to adjust its resistance in response to the interface control signal. Adjusting the resistance of the interface circuit causes the voltage of the output-control signal to be adjusted, thus causing the power supply circuit to adjust the regulated output voltage.Type: GrantFiled: November 28, 2011Date of Patent: September 24, 2013Assignee: Agere Systems LLCInventors: Kouros Azimi, Mohammad S. Mobin, Gregory W. Sheets, Lane A. Smith

Patent number: 8280347Abstract: A mobile device is configured with electrical circuitry that causes the transmit channel electrical circuitry of the transmitter (Tx) of the mobile device to be electrically coupled to the receive channel electrical circuitry of the receiver (Rx) of the mobile device when one or more predetermined conditions occur. The electrical coupling of the transmit channel circuitry to the receive channel circuitry causes the Rx to be sufficiently damaged to render the mobile device nonoperational, thereby preventing further use of the mobile device. The one or more predetermined conditions correspond to conditions that indicate the mobile device has been lost or stolen and/or that an unauthorized user is attempting to use the mobile device in some manner.Type: GrantFiled: July 22, 2009Date of Patent: October 2, 2012Assignee: LSI CorporationInventors: Kouros Azimi, Anthony J.

Patent number: 8054415Abstract: In described embodiments, a thin film transistor (TFT) liquid crystal display (LCD) structure incorporates a white light emitting diode (LED) structure for backlighting. White LEDs are formed behind each TFT cell, allowing for display “black” as a function of a nematic layer, on the TFT substrate, while increasing intensity of the LED LCD backlight structure. A lens structure might be formed between the LEDs and the TFT substrate to reduce a number of LED sources for a given backlight intensity.Type: GrantFiled: August 24, 2009Date of Patent: November 8, 2011Assignee: LSI CorporationInventors: Roger Fratti, Kouros Azimi, Mohammad Mobin, Ian Hughes

Patent number: 7977989Abstract: Disclosed is a circuit that adjusts a characteristic of a signal transmitted from a transmitter to a receiver over a communication channel (e.g., a wire, a backplane, etc.). The circuit includes a latch that receives the signal at a predetermined point in the circuit and samples a voltage of the signal many times after a threshold voltage is applied to the latch. The circuit also includes a processor that determines the characteristic of the signal when the sampled voltages indicate a transition point and that adjusts the threshold voltage when the sampled voltages do not indicate a transition point. The processor adjusts the characteristic of the signal by adjusting at least one of a current and a voltage of the transmitter when the characteristic of the signal is outside a predetermined range.Type: GrantFiled: March 24, 2010Date of Patent: July 12, 2011Assignee: Agere Systems Inc.Inventors: Kouros Azimi, Mohammad S.

Patent number: 7948914Abstract: In described embodiments, elements of a wireless home network employ learned power security for the network. An access point, router, or other wireless base station emits and receives signals having corresponding signal strengths. Wireless devices coupled to the base station through a radio link are moved through the home network at boundary points of the home and the signal strength is measured at each device and communicated to the base station. Based on the signal strength information from the emitted signals measured at the boundary points and/or from measured signal strength information of signals received from the boundary points, the base station determines a network secure area. The base station declines permission of devices attempting to use or join the home network that exhibit signal strength characteristics less than boundary values for the network secure area.Type: GrantFiled: January 28, 2009Date of Patent: May 24, 2011Assignee: Agere Systems Inc.Inventors: Kouros Azimi, Mohammad Mobin, Roger Fratti, Sailesh Merchant, Kenneth Paist

Publication number: 20100331628Abstract: In described embodiments, a data collection device receives signals from one or more patient monitoring devices, the signals representing patient data and other vital signs measured at a patient. The data collection device employs statistical quality algorithms to track irregular behavior and out-of-bound events, the behavior and events either being pre-set, adaptively set, or otherwise defined within pre-determined limits. The data collection device communicates alerting signals to a caregiver's handheld device when the irregular behavior and out-of-bound events occur. The alerting signals contain information related to the patient data, irregular behavior and out-of-bound events, thereby allowing a caregiver to take appropriate action.Type: ApplicationFiled: June 29, 2009Publication date: December 30, 2010Inventors: Sailesh Merchant, Kouros Azimi, Mohammad Mobin

Publication number: 20100250234Abstract: In described embodiments, a point of sale system, such as a cash register, provides for translation from standard language to desired native language on a receipt. Translation might be initiated through user (e.g., purchaser) input, manually or from a credit card, for example, and translation is accomplished through a database accessed by the point of sale system. Consequently, the point of sale system provides at least one receipt to the purchaser that identifies purchases as line item descriptions, and, in some cases, the price paid for each line item, in the purchaser's native language that might be used, for example, to accurately prepare vouchers.Type: ApplicationFiled: March 30, 2009Publication date: September 30, 2010Inventors: Kouros Azimi, Sailesh Merchant
