Patent number: 7940026Abstract: A power manager for managing power delivered to a battery operated peripheral device is disclosed. The power manager includes an input current limiter arranged to suppress a power surge associated with an insertion event by a power cable arranged to provide an external voltage. A voltage converter unit coupled to the input current limiter converts the received external voltage to a supply voltage that is transmitted by way of a main bus to a voltage sensor unit coupled thereto. During the insertion event, a comparator unit coupled to the voltage sensor, sends a first switching signal to a switchover circuit that responds by connecting the peripheral device and an uncharged battery to the main bus such that the supply voltage is provided thereto. When the battery is substantially fully charged, the switchover circuit responds by electrically disconnecting the battery so as to not overcharge the battery.Type: GrantFiled: December 9, 2009Date of Patent: May 10, 2011Assignee: Apple Inc.Inventors: Anthony M. Fadell, Christoph Krah

Patent number: 7451250Abstract: In a portable FireWire compatible device, a direct memory access (DMA) bus switch coupled by way of a DMA bus to a central processing unit (CPU), a local hard drive (HDD), and a FireWire port, provides a direct connection between the FireWire port and the HDD bypassing a main bus and the CPU when a data transfer request is received and processed by the CPU. Otherwise, until the data transfer request is received and processed, the CPU is directly connected to the HDD. In this way, a high speed data transfer between the FireWire port and the HDD is provided only when an appropriate data transfer request is received and processed.Type: GrantFiled: February 27, 2006Date of Patent: November 11, 2008Assignee: Apple Inc.Inventors: Anthony M.

Publication number: 20080062140Abstract: Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.Type: ApplicationFiled: June 8, 2007Publication date: March 13, 2008Applicant: Apple Inc.Inventors: Steve Hotelling, Wei Chen, Christoph Krah, John Elias, Wei Yao, John Zhong, Andrew Hodge, Brian Land, Willem Den Boer
