Patent number: 7039203Abstract: A plurality of audio inputs which require gain applied are coupled together, the gain is applied and that weighted signal is summed with the output of similar circuits running with different gains. For typical overall gain requirements of 0 to +22.5 dB to be applied in 1.5 dB increments, the new circuit reduces by over two-thirds the number of analog switches required in the level adjusting portion of an audio mixer. More generally, the complexity of the new circuit, in terms of the number of analog switching elements is 2m(1+log2n) for m channels with n gain steps/channel. The number of stages of differing gain is reduced from 2m variable gain amplifiers to 2(1+log2n) fixed gain amplifiers.Type: GrantFiled: December 31, 2001Date of Patent: May 2, 2006Assignee: Apple Computer, Inc.Inventor: Lawrence F.

Publication number: 20060066588Abstract: An input device and system are described that acquires (measures) raw track pad sensor data and transmits this data to a host computer where it is analyzed by an application executing on one or more host computer central processing units. The resulting input processing architecture provides a track pad input device that is both lower in cost to manufacture and more flexible than prior art track pad input devices. Lower costs may be realized by eliminating the prior art's dedicated track pad hardware for processing sensor data (e.g., a processor and associated firmware memory). Increased flexibility may be realized by providing feature set functionality via software that executes on the host computer. In this architecture, track pad functionality may be modified, updated, and enhanced through software upgrade procedures.Type: ApplicationFiled: September 21, 2005Publication date: March 30, 2006Applicant: Apple Computer, Inc.Inventors: Benjamin Lyon, Stephanie Cinereski, Chad Bronstein, Steven Hotelling

Publication number: 20060061927Abstract: 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: ApplicationFiled: November 10, 2005Publication date: March 23, 2006Applicant: Apple Computer, Inc.Inventors: Anthony Fadell, Christoph Krah

Patent number: 7016891Abstract: A system and method is described which provides for context checking of an operating environment. A context manager controls the execution of context checks requested by applications or processes. In one embodiment, the context check modules are defined as self-contained modules located in a database. When the data base is opened, these modules are loaded and registered with the context manager. Upon occurrence of certain user actions, the context manager will issue an event to cause the appropriate modules to perform a context check of certain context of the environment. The resulting context information is stored in memory by the context manager and provided to the applications by the context manager when needed. One advantage is that the context checks performed can be changed simply by adding or deleting modules from the database.Type: GrantFiled: June 26, 2002Date of Patent: March 21, 2006Assignee: Apple Computer, Inc.Inventor: John Richard Powers, III
