Patent number: 8331883Abstract: Circuitry for portable electronic devices is provided. The circuitry may include wireless communications circuitry and storage and processing circuitry. The wireless communications circuitry may include an antenna and a radio-frequency power amplifier with an adjustable gain mode. The radio-frequency power amplifier may amplify radio-frequency signals to a given output power. The circuitry may include an adjustable power supply circuit that supplies an adjustable power supply voltage to the power amplifier circuitry. The circuitry may also include a transceiver that produce radio-frequency signals at a specified input power to the power amplifier circuitry. The storage and processing circuitry may be used in storing calibration data. The calibration data may specify adjustments to be made to the input power to the radio-frequency power amplifier, the gain mode setting of the power amplifier, and the power supply voltage for the power amplifier to optimize performance while minimizing power consumption.Type: GrantFiled: October 30, 2008Date of Patent: December 11, 2012Assignee: Apple Inc.Inventor: Robert Sorensen

Patent number: 8255009Abstract: Portable electronic devices are provided with wireless circuitry. The wireless circuitry may include one or more sets of radio-frequency power amplifiers. The radio-frequency power amplifiers are used to amplify radio-frequency signals that are transmitted by the portable electronic devices. Each power amplifier may have multiple gain mode settings. Gain stages within the power amplifiers may be selectively enabled in accordance with the gain mode settings. When a higher level of gain is required, all of the gain stages may be enabled. When a lower level of gain is required, some of the gain stages may be disabled to conserve power. An adjustable power supply may be used to provide an adjustable power supply voltage to the power amplifiers. The adjustable power supply voltage can be reduced when it is desired to minimize power consumption at a particular gain mode setting. Gain mode and power supply settings may be adjusted simultaneously.Type: GrantFiled: April 25, 2008Date of Patent: August 28, 2012Assignee: Apple Inc.Inventors: Robert Sorensen, Ronald William Dimpflmaier

Patent number: 8116703Abstract: Portable electronic devices are provided that contain radio-frequency transceiver circuitry. Power amplifier circuitry may amplify transmitted radio-frequency signals from the radio-frequency transceiver circuitry. The power amplifier circuitry may be powered with a power supply voltage. The power supply voltage may be reduced to conserve power provided that requirements such as adjacent channel leakage ratio requirements are satisfied. Calibration measurements may be made to determine the extent to which power can be conserved by power supply voltage reductions. During calibration, the transceiver circuitry may transmit signals in a transmit subband. Test equipment that is external to the device may frequency shift the transmitted signals into a receive subband. The frequency-shifted signals may be fed back into the device. The transceiver circuitry in the device may make power measurements on the fed back signals. The power measurements may be used to compute adjacent channel leakage ratio values.Type: GrantFiled: December 8, 2008Date of Patent: February 14, 2012Assignee: Apple Inc.Inventor: Robert Sorensen

Patent number: 8021447Abstract: Hydrogen-producing fuel processing assemblies for producing hydrogen gas. The assemblies include a catalyst chamber, a heat source adapted to heat the catalyst chamber, a hydrogen-producing region within the catalyst chamber adapted to produce hydrogen gas from a feed stream, and a conductive guide structure within the catalyst chamber adapted to conduct and distribute heat from the heat source within the hydrogen-producing region and to direct fluid through the hydrogen-producing region. In some embodiments, the conductive guide structure includes a helical member. In some embodiments, the assembly further includes a vaporization region within the catalyst chamber. In some embodiments, the fuel processing assembly is adapted to produce hydrogen gas via a steam reforming or other endothermic reaction.Type: GrantFiled: July 30, 2008Date of Patent: September 20, 2011Assignee: Idatech, LLCInventors: Vernon Wade Popham, Robert A.

Publication number: 20100197363Abstract: During a telephony session, a determination is made on a mobile computing device that one or more designated conditions exist by which radio interference generated from the mobile computing device is to be reduced. In response, a power state of a set of one or more components of the mobile computing device is lowered. This reduces radio interference from those components. The set of components are ancillary to the mobile computing device's ability to maintain the telephony session, so that the telephony session is not affected by the reduction of power to the components.Type: ApplicationFiled: April 12, 2010Publication date: August 5, 2010Inventors: Robert Sorensen, Jerome Tu
