Abstract: A communication system (200) comprises a radio communication device (100) comprising a controller (102) having law enforcement information (110) stored therein and a data acquisition device (108) for capturing area conditions surrounding a law enforcement vehicle or law enforcement personnel. The controller (102) detects violations of the law enforcement information based on variety of detection devices, such as video analytics. In response to a detection of a law violation by an offending vehicle, a transmitter (104) within communication device 100 generates an alert to similarly formed secondary devices (220) mounted and/or worn within the network. The system (200) provides an automated response through devices (220) by gathering additional data pertaining to the offending vehicle to detect for additional violations of the law, even across state lines. The system (200) may further facilitate apprehension of an offending vehicle through automated roadblocks.

Abstract: Methods for reducing sensor support power in a sensor network include a primary node locating a secondary node. The primary node has a primary node sensor profile, and the secondary node has a secondary node sensor profile. The secondary node sensor profile is compared to the primary node sensor profile.

The virtual sensor profile reduces redundant sensor data gathering between the primary and secondary sensor nodes. A power consumption optimization hardware configuration for the secondary node is determined to provide sensor data for the virtual sensor profile, and the determined hardware configuration is assigned to the secondary node.

The method can include monitoring (302) a power-level of the mobile device, determining (304) if the power-level is below a pre-determined threshold, identifying (306) peers to serve as transmit proxies in view of the power-level, and switching from a high-power transceiver (206) to a low-power transceiver (208) to reduce power consumption. The mobile device can communicate with the peers using a low-power transceiver in the WLAN to transmit communication data within the WAN.

A coupled electrical circuit (130) is operable to selectively energize the first portion (116) to create a force that moves the first portion (116) toward its memory state which moves the second portion (118) in a first direction out of its memory state, and to selectively energize the second portion (118) to create a force that moves the second portion (118) towards its memory state which moves the first portion (116) away from its memory state in a second direction different from the first direction. A feedback system (120) is preferably included to provide for precise motion control.

Abstract: A communication device provides for a hardware configurable module interface port by using a programmable logic device (108). The programmable logic device (108) is reconfigured using software stored in memory (106). The reconfiguration of programmable logic device (108) depends on the type of module (110) that is attached to the communication device. Since data translation is not required to be performed by each of the different types of modules that can be attached to the communication device, the time to develop a module is shortened and support circuitry requirements to perform data translation is reduced.

Abstract: A variable inductor is made from two elements separated by an insulating layer. The first element is elastic and serves as a coil shaped support for the inductive element. This elastic element is made with a memory and can be made to change its size by the application of heat. The inductive element is formed over the coil shaped support by layering a thin layer of a highly conductive material such as gold over the insulator layered on the elastic element. As heat is applied to the coil or as an electric current is applied to the elastic element, the size of the coil shaped support is changed which changes the inductive value of the inductive element formed by the conductive layer.

When in the second operating mode, the received message is converted to audible form, preferably using a text-to-speech synthesizer, and presented to the user via the earpiece (430, 455, 460, 465).
