摘要:
Wireless electronic devices may include a transceiver, an antenna resonating element coupled to the transceiver via a transmission line path, transceiver and antenna impedance matching circuits, and other circuitry. The transceiver and the impedance matching circuits may be formed on a first substrate. The antenna resonating element may be formed using a second substrate. The antenna resonating element may be decoupled from the first substrate during testing. First and second sets of test points may be formed at first and second locations long the transmission line path. During testing, a test probe may mate with the first set of test points, whereas an impedance adjustment circuit that serves to electrically isolate the antenna impedance matching circuit from the transceiver may mate with the second set of test points. The impedance adjustment circuit need not be used if the antenna impedance matching circuit is decoupled from the transceiver during testing.

Event-based modes of operation are supported on an electronic device. One or more event-based modes of operation may be automatically or selectively applied to the device when a new life event is detected. The device's previous mode of operation may be backed up to the device or a network location and restored after the event-based mode of operation is no longer applied. The event-based modes of operation may be used to restrict access to certain applications or functionalities on the device, enforce or restrict certain user interface or other types of settings, and add or remove or rearrange the priority of device assets. The new life events associated with event-based modes of operation may be of various types, including location-based events, environment-based events, calendar-based events, news-based events, and usage-based events.

A portable handheld test fixture has an acoustic port, e.g. a speaker port, a microphone, and/or an earpiece/receiver port. Once the media device has been installed onto the test fixture, the port becomes acoustically coupled to a respective acoustic aperture of the media device that is associated with a speaker, a microphone, or an earpiece/receiver as the case may be. A sound test tool, e.g. a reference sound source and/or a sound pressure level, SPL, meter, has an input or output sound port that can be removably coupled to the acoustic port of the test fixture. Other embodiments are also described and claimed.

A test station may include a test host, a signal generator, and a test chamber. Multiple devices under test (DUTs) may be placed in the test chamber during device characterization operations. Radio-frequency signals may be conveyed from the signal generator to the multiple DUTs using a radiated arrangement through an antenna in the test chamber. The signal generator may broadcast downlink test signals. The DUTs may synchronize with the downlink test signals and measure radio-frequency performance levels while receiving the downlink test signals. The test host may direct the signal generator to gradually lower its output power level. The DUTs may be used to determine downlink sensitivity by monitoring the measured radio-frequency performance levels as the output power level of the signal generator is lowered. Downlink sensitivity testing may be performed across any desired radio-frequency bands and channels.

A method and apparatus for a mobile device to set an alarm based on an external request is described. In one embodiment of the invention, the mobile device receives the external request which includes a set of one or more parameters at least partially defining the alarm and a set of one or more actions to take upon the alarm triggering. Upon determining that the external request is trusted, the mobile device automatically sets the alarm on the mobile device according to the set of parameters included in the request. Upon the alarm triggering, the mobile device performs the set of actions included in the external request. Other methods and apparatuses are also described.

The present invention can permit a communications request initiator to control pre-communications interactions. For example, the present invention can permit a communications request initiator to instruct a recipient communications device to present specific information to a communications request recipient when the initiator sends the communications request to the recipient. The present invention also can permit a communications request initiator to control the information presented to the initiator when he is waiting for a communications request recipient to respond to the communications request.
摘要:
During an ongoing wireless telephone call communication session between a pair of mobile devices, a local device responds to its user's activation of a virtual or actual button or key, or its user's verbal command, by automatically sending an over the air message (e.g., a SMS or text message or other network communication message) to the remote device. The message requests location information of the remote device. Upon obtaining location information from the remote device, a location of the remote device is automatically displayed on the local device. Other embodiments are also described and claimed.
摘要:
Wireless test equipment may be used to perform over-the-air testing of user equipment. The user equipment may contain an antenna and a receiver. The wireless test equipment may contain a call box that performs network-level testing by sending and receiving protocol-compliant network messages. The call box may transmit a radio-frequency test signal at a predetermined power. The antenna in the user equipment may receive the radio-frequency test signal and may provide the received radio-frequency test signal to the input of the receiver. The call box may send a network message such as a code-division-multiple-access intercode handover command to the user equipment to direct the user equipment to measure the received radio-frequency test signal power at the input of the receiver. The measured power may be transmitted to the call box as part of a pilot measurement message indicator, using an intercode handover command, or using other network messages.

摘要:
Two or more acoustic transducers share the same acoustic port in a device. The acoustic properties—such as acoustic impedance and frequency response—of the shared acoustic port are matched to each of the two or more acoustic transducers. To accomplish acoustic impedance matching, a separate back volume is provided for each of the acoustic transducers, matched to that transducer. Frequency response matching can be accomplished by the design of the transducer itself, but also by providing an adjacent element in the acoustic system of the transducer. One transducer may serve as an element in the acoustic system of another transducer. Frequency response adjustment of an individual element may also affect acoustic impedance of the entire port-transducer system.
