Appl. No.:

12/186306

Inventors:

Daniel A. Warren - San Jose CA, US
Michael Rosenblatt - Campbell CA, US

Assignee:

Apple Inc. - Cupertino CA

International Classification:

H02J 9/00
H02J 1/00

US Classification:

307 64, 307 71, 307 77, 320101

Abstract:

This is directed to methods, systems, and apparatuses for implementing circuitry that can be used to control multiple solar cells to generate power for a portable electronic device. For example, in response to determining that one or more of the solar cells is generating a reduce voltage output (e. g. , due to a partial obstruction of one or more of the solar cells), the connections among the solar cells can be configured to generate a constant preset voltage, as long as a subset of the solar cells is operating. The voltage generated by the solar cells can then be boosted to a value suitable for powering the portable electronic device and/or any of its individual components. As another example, the connections among the solar cells can be configured to generate a startup voltage to directly power the portable electronic device and/or any of its components.

Assignee:

Apple Inc. - Cupertino CA

International Classification:

G06F 19/00

US Classification:

702108

Abstract:

Systems and methods are disclosed for a self-testing power management unit (PMU) in an electronic device. Self-testing may enable the testing of PMU power supply outputs while reducing the need for test points to conserve circuit board real estate. In one embodiment, a PMU is placed in self-test mode, and a test controller may perform capacitance tests on each power supply output. Once the capacitance test has been performed on each power supply output, the PMU may be placed in normal operating mode, and voltage tests may be performed on each power rail. Once voltage tests have been performed on all power rails in the PMU, the self-test may be complete. In some embodiments, the test controller may communicate with a test multiplexer to select the power supply output for testing. Further, the measurements resulting from the capacitance and voltage tests may be converted to a digital signal through an analog-to-digital converter on the PMU.

Assignee:

Apple Inc. - Cupertino CA

International Classification:

G06F 3/00

US Classification:

710 5

Abstract:

Apparatus and methods for setting up an action on an electronic device before an input is confirmed and performing the action once the input is confirmed are provided. The amount of time needed to perform the action in response to detecting an input may be reduced by an amount of time equivalent to the lesser of the wait time used to confirm the input or the time needed to set up the action. The electronic device may set up a predicted action to be performed substantially immediately following confirmation of the input.

Abstract:

Systems, methods, and machine-readable media are disclosed for controlling an electronic device using data transmitted over radio signals. In some embodiments, a radio source may embed instructions to control an electronic device into a radio signal. For example, the radio source may use the RDS communications protocol to transmit the instructions in an FM radio signal. The electronic device may receive the radio signal and may perform the instructions included in the radio signal. For example, in a testing environment, the instructions can include commands to test the electronic device's radio using test parameters specified in the instructions. Responsive to receiving the test parameters, the electronic device may configure itself (e.g., turn on or off certain components) and record audio from a specified radio station.

US Classification:

375316

Abstract:

Devices and methods for dynamically selecting a matching network for an antenna are provided. In one example, an electronic device capable of selecting such a matching network may include an antenna, several selectable matching networks, a radio receiver, and matching network control circuitry. The radio receiver may couple to the antenna via one of the selectable matching networks to receive a radio signal with both an analog and digital component. The matching network control circuitry may select the matching network from among the several selectable matching networks based at least in part on a characteristic of the digital component of the radio signal.

US Classification:

236 1 C, 29428, 439775

Abstract:

A thermostat and related methods is provided for controlling an HVAC system. The thermostat includes wiring terminals adapted and configured to make an electrical connection with an HVAC system wires such as common, heating and cooling control and return wires. The making of the connection with a common wire actuates switching open a loop of an electrical circuit used for power harvesting. According to some embodiments, the wiring terminal includes actuation of a moveable part of the terminal so as to accommodate the common wire that in turn actuates the switching open the power harvesting loop. More than one other loop can be switched. According to some embodiments, the wiring terminal can be used to automatically connect and/or disconnect Rc and Rh circuits when one or both Rc and Rh wires are present. According to some embodiments, the wiring terminal can be used for electronically sensing the presence of the HVAC system wire.

International Classification:

US Classification:

700276

Abstract:

A user-friendly, network-connected learning thermostat is described. The thermostat is made up of (1) a wall-mountable backplate that includes a low-power consuming microcontroller used for activities such as polling sensors and switching on and off the HVAC functions, and (2) separable head unit that includes a higher-power consuming microprocessor, color LCD backlit display, user input devices, and wireless communications modules. The thermostat also includes a rechargeable battery and power-stealing circuitry adapted to harvest power from HVAC triggering circuits. By maintaining the microprocessor in a “sleep” state often compared to the lower-power microcontroller, high-power consuming activities, such as learning computations, wireless network communications and interfacing with a user, can be temporarily performed by the microprocessor even though the activities use energy at a greater rate than is available from the power stealing circuitry.

International Classification:

H04R 25/00

Abstract:

An acoustic apparatus and method produces an acoustic signal in response to an electrical input signal applied to an acoustic receiver. The acoustic signal is converted to an electrical output signal that is proportional to a sound pressure of the acoustic signal, using an electro-acoustic transducer. In some embodiments the apparatus and method determine whether there is a change in the acoustic signal indicative of a change in an acoustic load coupled to the receiver by comparing the electrical output signal to reference information. The change in acoustic load, in one example, is attributable to ear wax accumulation in an output of the acoustic receiver or acoustic passage in the ear canal of a user or is attributable to seal leakage.
