Inventors:
Paolo Sacchetto - Cupertino CA, US
Eric G. Smith - Palo Alto CA, US
William C. Athas - San Jose CA, US
Assignee:
APPLE INC. - Cupertino CA
International Classification:
G06F 1/26

Time-Domain Multiplexing Of Power And Data

US Patent:
2012028, Nov 8, 2012
Filed:
Nov 1, 2011
Appl. No.:
13/286982
Inventors:
Eric Smith - Palo Alto CA, US
Bryan R. Hinch - Mountain View CA, US
Tommee So - Milpitas CA, US
Assignee:
Apple Inc. - Cupertino CA
International Classification:
H02J 3/00, H01H 35/00
US Classification:
307 2, 307130
Abstract:
Circuits, methods, and apparatus that may allow an electronic device to control a power adapter. One example may provide an electronic system where an electronic device may control a power adapter through a communication channel. Data transferred in the communication channel may include the temperature of the power adapter, the charging capability of the adapter, and other types of data. In one example, power and data may share the same two wires, and the power and data may be time-division multiplexed. That is, the two wires may convey power and data at different times. Another example may include circuitry to detect a connection between the electronic device and the power adapter. Once a connection is detected, power may be transferred from the power adapter to the electronic device. This power transfer may be interrupted on occasion to transfer data between the power adapter to the electronic device.

Controlling An Adapter Transformer Voltage

US Patent:
2014004, Feb 13, 2014
Filed:
Aug 7, 2012
Appl. No.:
13/568414
Inventors:
Louis Luh - Sunnyvale CA, US
Eric G. Smith - Palo Alto CA, US
P. Jeffrey Ungar - Sunnyvale CA, US
Assignee:
APPLE INC. - Cupertino CA
International Classification:
H02M 3/335
US Classification:
363 17
Abstract:
Embodiments of an adapter are disclosed that include a transformer with a primary coil coupled to an H-bridge. The H-bridge is controlled by a control circuit that controls a voltage across the primary coil using the H-bridge, and the control circuit is configured to control the H-bridge so that during each of one or more intervals, a first voltage pulse is applied across the primary coil in a start direction, wherein the start direction alternates between a first direction and a second direction each interval. Then, a direction of subsequent voltage pulses across the primary coil is alternated between the first direction and the second direction a predetermined number of times. After the predetermined number of times, a last voltage pulse is applied across the primary coil; then, voltage across the primary coil is reduced to zero for a predetermined time.

Controlling An Adapter Transformer Voltage

US Patent:
2014004, Feb 13, 2014
Filed:
Aug 8, 2012
Appl. No.:
13/570031
Inventors:
Louis Luh - Sunnyvale CA, US
Eric G. Smith - Palo Alto CA, US
Assignee:
APPLE INC. - Cupertino CA
International Classification:
H02M 3/335
US Classification:
363 17
Abstract:
An adapter for electrical power that includes a rectifier coupled to a transformer with a primary coil and a secondary coil. The secondary coil includes a first end tap, a second end tap, and a center tap. A first switch is coupled between the first end tap and a primary side ground. A second switch is coupled between the second end tap and the primary side ground. A controller is coupled to the first switch and to the second switch so that during one or more intervals, the first switch and the second switch are alternately open and closed a predetermined number of times, wherein the initial switch closed each interval alternates between the first switch and the second switch, and after the predetermined number of times, both the first switch and the second switch are opened for a predetermined time period.

Audio Sensors

US Patent:
2012030, Dec 6, 2012
Filed:
Jun 6, 2011
Appl. No.:
13/153990
Inventors:
Aleksandar Pance - Saratoga CA, US
Brett Bilbrey - Sunnyvale CA, US
Eric George Smith - Palo Alto CA, US
Jahan Christian Minoo - San Jose CA, US
Assignee:
Apple Inc. - Cupertino CA
International Classification:
G06F 3/043
US Classification:
345177
Abstract:
One embodiment may take the form of an audio detection system having a display assembly. The display assembly may include a screen and at least one electromagnetic energy emitter configured to direct energy at an inside surface of the screen. At least one sensor is configured to sense the emitted energy after it is reflected from the inside surface of the screen and generate electrical signals corresponding the sensed reflected energy. A processor coupled to the at least one sensor generates an audio signal representative of sound waves that impact an outer surface of the screen.

Assignee:
APPLE INC. - Cupertino CA
International Classification:
H02M 3/335
US Classification:
363 17, 363 16
Abstract:
