    Abstract: An electronic device is described. During operation, this electronic device activates a communication channel having a carrier frequency in a radio in an interface circuit to listen for an advertising frame of interest from another electronic device during a scan window having a predefined duration. If the advertising frame of interest is received from the other electronic device, the electronic device terminates the listening before the predefined duration has expired and, using the communication channel in the radio, transmits the connect request to the other electronic device to establish the connection with the other electronic device. In this way, the delay between discovery of the other electronic device and establishing the connection is reduced. In addition, the power consumed by the electronic device while scanning for the other electronic device and initiating the connection is reduced.

    Abstract: Methods for operating portable electronic devices to maintain accurate timing information are provided. In one suitable arrangement, an electronic device may have a real-time clock and a mach-time clock that can be used separately to track the Coordinated Universal Time (UTC). The offset of the real-time clock and the mach-time clock from UTC can be monitored to determine if there is any oscillator frequency drift, which can be characterized using a linear model. Any variation in drift caused by environment factors such as temperature may also be characterized. In another suitable arrangement, a primary electronic device that is capable of maintaining accurate timing information may transfer that information to a secondary user device. Timing information may be transferred using mach-time values and may then be converted to real-time clock values to ensure that the secondary user device can estimate time accurately even when the device goes to sleep.

    Abstract translation: 提供了用于操作便携式电子设备以维持准确的定时信息的方法。 在一个合适的布置中，电子设备可以具有可以单独使用的跟踪协调世界时（UTC）的实时时钟和机时时钟。 可以监视实时时钟的偏移量和来自UTC的机械时钟时钟，以确定是否存在振荡器频率漂移，这可以使用线性模型进行表征。 也可以表征由环境因素如温度引起的漂移的任何变化。 在另一种合适的布置中，能够维持准确定时信息的主电子设备可以将该信息传送到次用户设备。 可以使用机械时间值传送定时信息，然后可以将其转换为实时时钟值，以确保辅助用户设备即使在设备进入睡眠时也可准确估计时间。

    Abstract: A proximity fence can be a location-agnostic fence defined by signal sources having no geographic location information. The proximity fence can correspond to a group of signal sources instead of a point location fixed to latitude and longitude coordinates. A signal source can be a radio frequency (RF) transmitter broadcasting a beacon signal. The beacon signal can include a payload that includes an identifier indicating a category to which the signal source belongs, and one or more labels indicating one or more subcategories to which the signal source belongs. The proximity fence defined by the group of signal sources can trigger different functions of application programs associated with the proximity fence on a mobile device, when the mobile device moves within the proximity fence and enters and exits different parts of the proximity fence corresponding to the different subcategories.
