摘要:
A risk management system (100) for first responders (102) equips first responders with physiological and environmental sensors (104) in order to track the stress conditions and stress responses of the first responders. Data from the sensors is digitized and filtered and processed through a feature extraction system (202, 704) that may include noise filters, (710) derivative filters (706), integrators (708) and derived signal generators (712) that use stored data on first responders, before being fed into a pattern recognition system (402, 900) that assesses the risk state of the first responder. Data from multiple first responders in a team can be aggregated to obtain team risk assessments.

Embodiments of the invention generally provide a method and apparatus for enabling digital rights management in file transfers. One embodiment of a method for transferring digital content from a first user to a second user, includes transferring ownership of an instance of the digital content to the second user, where the instance of the digital content resides on a first device belonging to the first user. Copies of the digital content are then deleted from one or more additional devices belonging to the first user (including at least one offline device).

A strain sensor (10) includes a flexible substrate (11) having one or more polymer-based resistive elements (12) at least partially conformably disposed thereon. Two or more conductive leads (13, 14) are electrically coupled to the resistive element. Flexure of the resistive element causes a corresponding alteration in a measurable electrical property of the resistive element, such as its characteristic impedance. User interfaces of various kinds can be fabricated with such strain sensors.

A wireless, programmable system for bio-potential signal acquisition (e.g., electrocardiogram (ECG) data) includes a base unit and a plurality of individual wireless, remotely programmable transceivers that connect to patch electrodes. The base unit manages the transceivers by issuing registration, configuration, data acquisition, and transmission commands using wireless techniques. Bio-potential signals from the wireless transceivers are demultiplexed and supplied via a standard interface to a conventional monitor for display.

A distributed transmission line structure (10) includes a ground plane (26) affixed to a substrate (12). The substrate (12) is formed of a generally nonconductive material. A first metallic strip (14) is affixed to the substrate (12) and is electrically connected to the ground plane (26) through a first through-hole (34). A second metallic strip (16) is affixed to the substrate (12) and is spaced apart from the first metallic strip (14) by a gap (28) and is electrically connected to the ground plane (26) through a second through-hole (38). A dielectric layer (20) overlies the substrate (12), the first metallic strip (14), and the second metallic strip (16). A third metallic strip (18) is affixed to the dielectric layer (20) and is disposed to overlie the gap (28). The third metallic strip (18) has a width less than the gap (28). The impedance of the distributed transmission line structure (10) is substantially constant over a predetermined range of thickness of the dielectric layer (20).

This invention relates to a process for the preparation of a crystalline compound having an empirical formula LaCr.sub.x A.sub.1-x O.sub.4.yH.sub.2 O where A is a metal selected from the group consisting of Mg, Sr, Ca and Ba, x ranges from 0.99 to about 0.7 and y ranges from 0 to 0.15. The process comprises adding a solution of the appropriate metal salts to a solution of ammonium hydroxide thereby precipitating a hydroxide gel intermediate, which is dried and calcined in air to yield the resultant crystalline compound which has a huttonite structure. Additionally, this invention relates to a process for the preparation of a ceramic powder having the empirical formula LaCr.sub.x A.sub.1-x O.sub.3, where A is a metal selected from the group consisting of Mg, Sr, Ca and Ba, and x ranges from 0.99 to about 0.7. Finally, a ceramic composition having the empirical formula LaCr.sub.x A.sub.1-x O.sub.4.yH.sub.2 O having a huttonite structure is also disclosed.

Described are methods and devices for identifying a group that include various methods to determine a group. Also described are devices and methods for attempting communication with a missing member of the group include different manners in which to determine information related to an entry of a group. The described devices and methods may be particularly beneficial at the particular time the certain group members plan to be or are in communication with one another. In this way, in the event that two or more entries of a group planned to be in communication or are in communication in-real time, in accordance with the disclosed devices and methods, the parties may be able to bring one or more other entries of the group into the communication as needed or desired.

Disclosed are devices and methods of communication devices that are configured to be a part of clustered displays. A communication device may be a mobile communication device. Such a device may include a cluster module configured to determine that the device is a license owning unit, a content module configured to receive data including content via a transceiver when it is determined that the device is a license owning unit and a distribution module configured to transmit output data via a transceiver, the output data being at least one portion of the data. The license owning unit is determined based on the reception characteristics of the devices of the cluster. The distribution by the license owning unit to other devices in the cluster is at the lowest resolution of any of the devices of the cluster.
