Publication number: 20100205472Abstract: 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: ApplicationFiled: April 28, 2010Publication date: August 12, 2010Applicant: APPLE INC.Inventors: David John Tupman, Steven Bollinger

Publication number: 20100201615Abstract: A touch and motion sensitive input control configured to use a combination of touch sensor output and motion sensor output to determine if an input event has occurred at an input area. The touch and motion sensitive input control can detect a particular input event (e.g., a button press) when a touch sensor detects a touch at a particular input area at around the same time as a motion sensor detects a change in motion. Based on the amount and nature of the motion detected, this can indicate that a user intended to cause an input event other than one caused by a mere touching of the input area.Type: ApplicationFiled: February 12, 2009Publication date: August 12, 2010Inventors: David John TUPMAN, Tang Yew Tan, Richard Hung Minh Dinh, Stephen Paul Zadesky

Patent number: 7730326Abstract: Improved approaches to update computer program code residing within a computing device are disclosed. By maintaining a former version of the computer program code, the computing device remains operable even if the update to the computer program code fails. Hence, the invention permits reliable updates to computer program code, which is particularly useful for firmware (e.g., boot-up code) of computing devices. For control and security, each version of computer program code can include authentication information. Before the computer program code is used, the computer program code can be required to be authenticated using the authentication information.Type: GrantFiled: November 12, 2004Date of Patent: June 1, 2010Assignee: Apple Inc.Inventors: Muthya Girish, Guy Bar-Nahum, David John Tupman

Publication number: 20100020221Abstract: In accordance with some embodiments, a method is performed at a handheld electronic device having a built-in digital camera and a touch sensitive screen. The method includes detecting a multi-finger gesture on the touch sensitive screen, wherein the touch sensitive screen is serving as part of an electronic viewfinder of the camera; storing coordinates of a location corresponding to the detected multi-finger gesture; translating the stored coordinates to a selected area of an image that is captured by the camera and that is being displayed on the touch sensitive screen; contracting or expanding the selected area in response to the user's fingers undergoing a pinching movement or a spreading movement, respectively, while the detected multi-finger gesture remains in contact with the touch sensitive screen; and applying an automatic image capture parameter adjustment process that gives priority to the selected area.Type: ApplicationFiled: July 23, 2009Publication date: January 28, 2010Inventors: David John Tupman, E-Cheng Chang

Publication number: 20090278407Abstract: 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: ApplicationFiled: July 21, 2009Publication date: November 12, 2009Applicant: APPLE INC.Inventors: David John Tupman, Ken Herman, Barry Twycross
