摘要:
A circuit and method for bridging an analog signal between two integrated circuits operating at different supply voltages. The circuit is a two stage fixed gain amplifier. The first stage is a transconductance amplifier and the second stage is an operational amplifier. The first stage converts an input signal from a voltage into a current. The second stage converts the current signal to an output voltage signal.

A wireless mobile communication (WMC) device may be utilized to generate and/or maintain multimedia data files. Context data tags may be created to tag the generated multimedia data files, enabling identification of multimedia data files without directly accessing the contents of the multimedia data files. Context data tags may comprise such attributes as time/date stamps, location, subject, environment, scheduling, and/or biometric information. The WMC device may maintain user preference information, which is unique to the WMC device capabilities and/or to a specific device user. The user preference information may be utilized to specify attributes that may be utilized in creating context data tags for multimedia data files. The user preference information may be maintained in the WMC device and/or externally. Tagging operation may be performed dynamically, and a remote device may be utilized to perform tagging operations and/or to maintain the user preference information.

A first personal electronic (PE) device may enable generation, updating, and/or storage of user configuration information. The user configuration information may comprise information pertaining to device configuration and/or operational preferences specific to the device user and/or various use settings, connectivity, and/or use of available resources. The generation, updating, and/or storage of the user configuration information may be performed manually and/or automatically, and may be performed directly within the first PE device and/or via networked devices, which may communicatively coupled to the first PE device. A second PE device may be enabled to be communicatively coupled to the first PE device and/or the networked devices. The second PE device may then be enabled to download existing user configuration information from the first PE device and/or the networked device, and the downloaded user configuration may be utilized to configure the second PE device.

Methods and systems for level detector calibration are disclosed and may comprise calibrating a level detector integrated on-chip to eliminate an associated zero input offset voltage utilizing a replica bias circuit with no input ac voltage at the level detector or the replica bias circuit. The offset voltages of the level detector and the replica bias circuit may be combined to eliminate the associated zero input offset voltage of the level detector. The output signal may be generated by a difference of output signals from the level detector and the replica bias circuit. The level detector and the replica bias circuit may be biased utilizing a similar bias voltage. A plurality of known input voltages may be utilized to generate a corresponding plurality of output voltages of the level detector, generating a corrected transfer function that may be used to accurately set a transmitter power level.

A Wireless mobile communication (WMC) device may maintain user preference information, which is unique to the WMC device capabilities and the device user. WMC devices located in near proximity of each other may be enabled to form an ad hoc wireless network wherein each WMC device within the network may function as a router for other devices. Utilizing such routing capability within an ad hoc wireless network may allow WMC devices that are out of their wireless coverage area to use other WMC devices within such ad hoc wireless network to route any impending communication through such other WMC devices wherein these devices may have wireless connectivity to their coverage networks. WMC devices that are may have external connectivity may be enable to be selective in routing information and/or data from other WMC devices in the ad hoc network.

Methods and systems for an atomizing function for a mobile device are disclosed and may include discovering available resources via a handheld wireless communication device (HWCD) and assessing respective cost functions for processing tasks by the HWCD and/or the discovered resources. The tasks may be apportioned for local and/or remote execution by the HWCD and/or the discovered resources based on the assessed cost functions. The assessed cost functions may be dependent on factors comprising communication bandwidth, memory space, CPU processing power, and battery power, which may be weighted. The cost functions may be dynamically assessed, enabling dynamic reapportioning of the tasks, which may be apportioned based on latency, quality of service (QoS), priority and/or user preferences associated with the local and/or remote execution. The apportioning of the processing of the tasks may be based on the assessed cost functions, and a priority and/or a QoS associated with the task.
摘要:
A Wireless mobile communication (WMC) device may maintain user preference information, which is unique to the WMC device capabilities and the device user. The WMC device may modify and/or update the user preference information based on device use and information ascertained from applications running on the WMC device itself; for example scheduling applications. The user preference information may be utilized to create context data tags for generated data on the WMC device. Context data tags may comprise such information as time/date stamping, subject information, and/or location information. The context data tags may be utilized to tag the generated data, enabling continuous and improved cataloging. Improved cataloging may enable improved searchability of tagged data. Tagged data alternatively and/or additionally may be transferred and stored in a remote device for improved and secure back-up storage. The remote device may utilize context data tags for cataloging and storing received data.
