摘要:
Remotely controlled devices (110) are controlled by one or more wireless remote controllers (114). The remotely controlled devices (110) and wireless remote controllers (114) communicate to each other over a two-way wireless link. The system and method provide pre-defined profiles that limit the performance of the remotely controlled devices (110) in order to provide different operating characteristics with the same remotely controlled devices (110). The system and method further provide one or more forms of feedback to a user of the wireless remote controller (114), such as sounds, vibration, and the like. The feedback can be provided in response to detected events associated with the remotely control device (110), such as sharp turns and the like. The performance limits of the remotely controlled devices (110) is also able to be modified with operating time in order to simulate, for example, improved driver skills, fuel depletion and/or pit stops.
摘要:
A method for tracking objects in a way that conserves power resources. The method can establish a designed range defining a safe area based upon the broadcast signal of an anchor beacon. When the tracking device is within the designed range, the tracking device can be placed in a mode of low power consumption. Should the tracking device move outside of the designated range, then the tracking device can be placed in mode for active tracking. The level of power consumption can be achieved by only enabling a WAN transceiver in the active tracking mode.

A method of prepaying for usage time for a communication device can include increasing an available balance of a prepaid account linked to a communication device of a first user by a designated amount responsive to a request from a second user (910) and allocating a portion of the available balance of the prepaid account that is attributable to the designated amount for communicating with a designated user (915). The method further can include paying charges resulting from communications between the communication device of the first user and the designated user from the allocated portion of the available balance of the prepaid account (925).
摘要:
A method of tracking objects uses an anchor beacon that can emit a broadcast over a range that is detectable by an object tracking device. The object tracking device can automatically detect a presence or absence of the broadcast. When the broadcast is present, the object tracking device can take no action. When the broadcast is absent, the object tracking device can determine a current location for the object tracking device and can convey an OTA communication to a tracking server. The OTA communication can indicate the absence of the broadcast and can also including the current location. The tracking server can selectively send a notification to a previously designated communication device to notify a user that the object tracking device is outside the range.
摘要:
A communication accessory (110) that includes at least a first sensor (130) that indicates whether the communication accessory is being worn by a user. The communication accessory also can include a communications adapter (210) that communicates a signal (235) which indicates to a communication device (120) whether the communication accessory is being worn. The communication accessory further can include a controller (205) that processes at least one signal generated by the first sensor to determine whether the communication accessory is being worn by the user. The controller can enter the communication accessory into a standby state in response to the first sensor indicating that the communication accessory is not being worn. The controller can take the communication accessory out of the standby state in response to the first sensor indicating that the communication accessory is being worn.
摘要:
A method is used in a receiver (100) for aligning the receiver (100). The method has a step of intercepting and demodulating the FM signal, which includes data symbols. The method has a step of determining error rates, in which the error rates of at least two subsets of the data symbols are determined. Each subset includes a plurality of the data symbols modulated at a unique one of a plurality of frequency deviations. The at least two subsets include data symbols of two opposite polarities. The method has a step of generating a frequency control signal, in which the frequency control signal is determined based on the error rates. The method has a step of aligning a receiver section (105), in which the receiver section (105) is aligned to the FM signal by controlling a local oscillator (320)which is responsive to the frequency control signal.

摘要:
The present invention discloses a method for handling scheduling conflicts. The method can include a step of conveying scheduled events to a mobile communication device. Times associated with the events can be analyzed to determine potential conflicts. A set of previously established conflict resolution rules can be applied to the potential conflicts. Recommendations for resolving the potential conflicts can be generated based upon the applied rules. A notification of the potential conflicts and the generated recommendations can be presented to a user of the mobile device through an interface of the mobile communication device. The notifications and recommendations can occur a sufficient time before the potentially conflicting events occur to permit anticipatory actions to be taken to alleviate the conflicts before their occurrence.
