A method and apparatus for determining whether to enable a functionality of a battery powered device upon connection to a battery is embodied by providing at least one voltage threshold in a memory of the battery that corresponds to a usable operating range limit of the battery and that is accessible by the battery powered device. Upon connection to the battery, the battery powered device acquires the voltage threshold or thresholds from the battery and programs itself with the threshold or thresholds. The battery powered device then compares a voltage of the battery to the threshold or threshold to determine whether the enable the functionality.

Two devices () can be determined to be within near field communication (NFC) range of each other. Pairing information for a service can be conveyed over an out-of-band channel (). The out-of-band channel can be a near field communication (NFC) channel. The service can be a Bluetooth service provided via an in-band (e.g., BLUETOOTH) channel (). The conveying of the pairing information can require the first device () to request at least one desired service, to provide a device ID, and to provide an authorization code in a single message (). In response to the single message (), the second device () can either deny the request () or can convey resource use parameters for the desired service and an ID for the second device within a second single message (). Pairing the two devices () can require use of the authorization code and the resource use parameters.

Pairing devices using data exchanged in an out-of-band channel

A communication device performs a method for establishing a fast path for signaling priority data. The method includes: establishing a first short range wireless data path to a second communication device for exchanging non-priority data; and establishes a second autonomous short range wireless data path to the second communication device, for exchanging priority data, wherein the second short range wireless data path comprises a wireless serial communication channel such as a radio frequency communication Bluetooth (RFCOMM) channel. An application layer in an upper layer stack of the communication device establishes both the first and the second short range wireless data paths. Non-priority data communicated to the second communication device along the first short range wireless data path is processed by the application layer. However, priority data communicated to the second communication device along the second short range wireless data path bypasses the application layer.

Method and apparatus for priority signaling over a wireless serial communication channel

A communication system is provided having an improved user interface in which an audible indicator is played out from an audio accessory to confirm radio transmission of a message sent from the audio accessory in response to activation of a wireless push-to-talk (PTT). The wireless PTT may be located on the audio accessory itself or embodied as a standalone device. The wireless PTT may be operated in conjunction with a two-way radio and a wired or wireless audio accessory device. The audible indicator ceases being played out of the accessory in response to deactivation of the wireless PTT and ending of the radio transmission.

User interface for a communication system

A configurable interface system () couples an accessory () to a communication device (). The interface system utilizes a memory device () embedded in the accessory () that stores physical configuration and event mapping descriptors () pertaining to the accessory. The communication device () reads the physical configuration and event mapping descriptors and configures its external interface () in response thereto, preferably through the use of bi-directional GPIO lines ().

Interface system for an accessory and communication device

An antenna () and antenna interface system () are provided that allow both RF and baseband signals to be transported over a single antenna/communication device coaxial center connector (). A single wire memory device () is embedded into the antenna () and electrically coupled to the antenna's center conductor (). Frequency diplexing () is used to transport the single wire bus communications between the antenna () and the communication device, such as a radio ().

The diversity SCO digital audio technique () provides packet protection through statistical diversity by adding new audio modes () that operate within a Bluetooth framework (). Increased packet protection improves audio intelligibility and data transmission. The combination of a blind or signaled transmission of a redundant packet (or) in combination with a randomly faded frequency hop for each packet provide for enhanced reliability and link quality.

A connector () having multiple contacts () includes a supply contact (), a ground contact () and at least one other contact () for providing attach/detach detection to an accessory or accessory connector. The supply and ground contacts () are longer than the detect contact () so that power is connected prior to any of the other contacts and power is removed after any of the other contacts are detached. Logical control circuitry () interfaces with the connector () to minimize sparks upon detachment from the accessory ().

A surface acoustic wave (SAW) device (300) is formed from a leaky wave mode piezoelectric substrate (310) to have substantially reduced surface wave attenuation when operating at a particular frequency. The SAW device (300) includes a SAW pattern (322, 324), disposed on a surface (321) of the piezoelectric substrate, having a free surface portion (324) and a shorted surface portion (322). The SAW pattern (322, 324) is overlaid with a material (330), preferably glass, which has a thickness selected to reduce surface wave attenuation.

A semiconductor substrate with electronic circuitry (e.g., a transmitter or receiver) formed thereon and including interconnects. A ferrite disk bonded to the substrate so as to interact with the interconnects, when the ferrite disk is activated by a substantially constant magnetic field thereacross, to provide frequency selectivity within the electronic circuitry. A permanent magnet positioned adjacent to the ferrite disk to provide a substantially constant magnetic field across the ferrite disk so that the magnetic field produces resonance in the ferrite disk.

A three-terminal resonator device (200) resonant at a resonant frequency has a first terminal (201), a second terminal (202), and a common terminal (203). The resonator includes a surface acoustic wave transducer (290) disposed on a piezoelectric substrate (201). The SAW transducer (290) is comprised of a first sub-transducer (210) and a second sub-transducer (220) which respectively include a first set of electrodes (211,213) and a second set of electrodes (221,223).
