Abstract: An antenna apparatus, an electronic device and a decoupling method for the antenna apparatus. The antenna apparatus includes a first antenna unit and a second antenna unit, a first decoupling network including a first input port connected to a first feed source; a first output port connected to the first antenna unit; and a first decoupling port; a second decoupling network including a second input port connected to a second feed source; a second output port connected to the second antenna unit; and a second decoupling port; and a decoupling transmission line connected between the first decoupling port and the second decoupling port. The first decoupling network and the decoupling transmission line form a power divider, such that a power input from the first input port is distributed to the first antenna unit and the decoupling transmission line based on a power division ratio of the power divider.

Abstract: Turbocharger systems and related methods and devices are provided for determining rotational speed of a turbocharger. A speed sensing device is mounted to a turbocharger and includes an acceleration sensing arrangement and an acoustic sensing arrangement. The speed sensing device outputs an acceleration-based speed value as the current turbo speed when the acceleration-based speed is stable, and otherwise outputs an acoustic-based speed value to as the current turbo speed if the acoustic-based speed value stable or outputs an estimated value as the current turbo speed when both of the acceleration-based and acoustic-based speeds are unstable. In exemplary embodiments, the acceleration sensing arrangement and the acoustic sensing arrangement are provided on a common substrate.

Abstract: A method for configuring a proxy server is disclosed. The method includes: establishing a first speed performance indicator and a second speed performance indicator, wherein the first speed performance indicator is configured for indicating a minimum threshold speed of the proxy server, and the second speed performance indicator is configured for determining whether the proxy server reaches a predefined standard speed; and selecting at least one proxy server from multiple candidate proxy servers according to the first speed performance indicator and/or the second speed performance indicator, and configuring the selected proxy server as a currently used proxy server. An apparatus for configuring a proxy server is also disclosed.

Abstract: A method and system for updating an OS of an embedded device. The embedded device provides its current OS version information to a mobile operation network via a SMS message. The embedded device can provide its current OS version information to a mobile operation network in response to a request from a mobile operator network that has implemented the SyncML specifications promulgated by the Open Mobile Alliance (OMA). The mobile operator network interacts with the datacenter to provide the embedded devices's current OS version and get the address of the image update. The mobile operator service sends the address to the embedded device via another SMS message. The embedded device downloads the image update using the RF link via a global packet radio service (GPRS) connection.
