Patent number: 8754612Abstract: A gas gauge circuit has a power supply pin, a power return pin, power-on reset capability, and a communications signal pin. A reset control circuit is coupled between the power supply pin and the communications signal pin, or between the power return pin and the communications signal pin. The reset control circuit removes power to the gas gauge circuit in accordance with a control signal asserted on the communications signal pin. Other embodiments are also described and claimed.Type: GrantFiled: July 9, 2012Date of Patent: June 17, 2014Assignee: Apple Inc.Inventors: Timothy M. Johnson, Scott Mullins, David John Tupman

Patent number: 8688928Abstract: A portable media device and a method for operating a portable media device are disclosed. According to one aspect, a battery-powered portable media device can manage use of a mass storage device to efficiently utilize battery power. By providing a cache memory and loading the cache memory so as to provide skip support, battery power for the portable media device can be conserved (i.e., efficiently consumed). According to another aspect, a portable media device can operate efficiently in a seek mode. The seek mode is an operational mode of the portable media device in which the portable media device automatically scans through media items to assist a user in selecting a desired one of the media items.Type: GrantFiled: July 20, 2012Date of Patent: April 1, 2014Assignee: Apple Inc.Inventors: Andrew Bert Hodge, David John Tupman, Guy Bar-Nahum

Patent number: 8633679Abstract: Improved techniques to manage operation of a portable electronic device having a substantially depleted battery when power is available from an external, power-limited source are disclosed. In one embodiment of the invention, the substantially depleted battery can be initially charged while a power-intensive operation is delayed. Once the battery has adequate charge to assist the external, power-limited source in powering the portable electronic device, the power-intensive operation can be performed. In this manner, power consumption of a portable electronic device can be managed so that reliable operation is achieved without exceeding limits on power being drawn from an external, power-limited source.Type: GrantFiled: December 20, 2011Date of Patent: January 21, 2014Assignee: Apple Inc.Inventors: David John Tupman, Steven Bollinger

Patent number: 8581449Abstract: A portable power source is configured for use with an electronic device. The portable power source cooperates and communicates with the electronic device via a peripheral bus to which the electronic device is attachable. The portable power source includes circuitry to process a power request signal from the electronic device to determine whether a device connected to a bus interface of the portable power source is requesting power from the portable power source.Type: GrantFiled: September 9, 2010Date of Patent: November 12, 2013Assignee: Apple Inc.Inventors: David John Tupman, Doug M. Farrar, Joseph R. Fisher, Jr., Jesse L. Dorogusker, Donald J. Novotney

Patent number: 8457157Abstract: Electronic devices and equipment may communicate over a wired communications path. The wired communications path may include one or more wires and may be associated with a headphone cable. Data may be conveyed in the form of a digital data stream containing multiple traffic channels. The digital data stream may include superframes, each of which has multiple frames of data. The frames of data may each contain a number of data slots. Some of the slots in a superframe may be used exclusively by a particular one of the traffic channels. Boundary slots may be shared between traffic channels. Data interface circuitry may implement a data dispersion algorithm that determines the pattern in which data from each traffic channel is distributed within each boundary slot. Transmitting data interface circuitry may merge traffic channels into a single data stream. Receiving data interface circuitry may reconstruct the traffic channels.Type: GrantFiled: February 27, 2012Date of Patent: June 4, 2013Assignee: Apple Inc.Inventors: Wendell B. Sander, Barry Corlett, David John Tupman, Brian Sander, Jeffrey J. Terlizzi, Andrew Bright, Anup Sharma

Patent number: 8396196Abstract: An audio communications host device has a communications network interface, digitizing circuitry, and a headphone jack. A demultiplexer has an input coupled to receive a signal from a pin of the headphone jack, and multiple outputs coupled to inputs of the digitizing circuitry, respectively. An uplink audio processor receives digitized microphone signals from multiple outputs of the digitizing circuitry, and in response delivers an uplink signal to the communications network interface. The uplink signal contains audio from one or more of the digitized microphone signals. Other embodiments are also described and claimed.Type: GrantFiled: May 8, 2009Date of Patent: March 12, 2013Assignee: Apple Inc.Inventors: Wendell B. Sander, David John Tupman

Patent number: 8358273Abstract: Improved techniques for controlling power utilization of a display device are disclosed. The improved techniques reduce power consumption by lowering display intensity at appropriate times. In one embodiment, the display intensity can be controlled depending on the type of content being displayed. In another embodiment, the display intensity can be controlled depending on the characteristics of the content being displayed. In still another embodiment, the display intensity can be controlled depending on the type and characteristics of content being displayed. The improved techniques are well suited for use with portable media devices.Type: GrantFiled: May 23, 2006Date of Patent: January 22, 2013Assignee: Apple Inc.Inventors: Andrew Bert Hodge, Guy Bar-Nahum, Shawn R. Gettemy, David John Tupman

Patent number: 8332668Abstract: Improved techniques to recognize a power source on a peripheral bus and/or determine power available from the power source via the peripheral bus are disclosed. Typically, the peripheral bus is supported by a cable connected between a host device and an electronic device. In this case, the host device is a power source (e.g., power adapter or battery pack) and the cable is used to provide power from the power source to the electronic device. Hence, by understanding the power available from the power source, the electronic device can manage its power utilization so as to operate in a stable and reliable manner. The electronic device is, for example, a portable computing device. Examples of portable computing devices include a Portable Digital Assistant (PDA) and a portable media player.Type: GrantFiled: January 11, 2011Date of Patent: December 11, 2012Assignee: Apple Inc.Inventors: David John Tupman, Ken Herman, Barry Twycross
