Filed:

May 10, 2004

Appl. No.:

10/843533

Inventors:

John Mathew Depew - Sunnyvale CA, US

Assignee:

Apple Computer, Inc. - Cupertino CA

International Classification:

H05K007/20

US Classification:

361719, 361704, 361707, 257717, 257718, 257719, 165 803, 165185

Abstract:

An electronic assembly comprises a support board, an integrated circuit chip interconnected and coupled to the support board, and a thermal-gap-filler pad placed over the integrated circuit chip and in contact with an external device to dissipate heat generated by the integrated circuit chip. The electronic assembly further comprises a standoff structure disposed adjacent the thermal-gap-filler pad and coupled to the support board, the standoff structure configured to prevent excessive force from being applied onto the thermal-gap-filler.

Filed:

Jun 18, 2008

Appl. No.:

12/141715

Inventors:

John M. Depew - Sunnyvale CA, US

Assignee:

Apple Inc. - Cupertino CA

International Classification:

G05B 24/02

US Classification:

323318

Abstract:

A circuit or apparatus for providing intermittent or interruptible power to an electronic device. The circuit may provide power upon user initiation and interrupt that power in response to a user command, fault state, period of inactivity and so forth. As one example, interruptible power may be initially provided to activate or “power up” an electronic device and constant power provided after the initial activation. The initial powering up of the device may be facilitated by closing two contacts. The circuit may continue to provide power after the button is released through a monitoring and/or feedback mechanism.

Assignee:

Apple Inc. - Cupertino CA

International Classification:

H02P 1/04

US Classification:

318272, 318445, 417 22

Abstract:

Methods and apparatuses for improving cooling fan operation are disclosed. In one embodiment, a cooling fan's speed is maximized by adjusting a PWM signal driving the fan to change the switching point of the fan motor. In another embodiment, a method for starting a low speed cooling fan by incrementally increasing the amplitude of the PWM signal applied to the fan is disclosed. In a further embodiment, a method for controlling a fan and a fan sensor is disclosed. In this embodiment, a PWM signal is generated, a fan is driven using the PWM signal, a cycle of the PWM signal is modified, and the fan sensors is driven using the PWM signal during the cycle. In a further embodiment, a fan incorporating these improvements is disclosed.

International Classification:

G01R 31/36
G06F 19/00

US Classification:

702 63

Abstract:

A method and apparatus for monitoring battery life in a human input device powered by replaceable batteries includes repeatedly measuring battery charge by use of a measuring arrangement forming part of the input device. Battery charge is measured while the input device is in a relatively inactive condition and when it is in an active condition, and a time value is associated with each battery charge measurement. A usage model may be constructed based on the battery charge measurements, and calculation of an expected battery life may be based at least in part on the usage model.
