In certain embodiments, a method for managing operational parameters of a cognitive radio device to minimize non-compliance with a regulatory policy involves sensing a change in an operational condition that will affect compliance with a current operational policy; estimating a time at which the current operational policy will become invalid; selecting a method for determining how to update the current operational policy; and updating the current operational policy of the cognitive radio device. Other embodiments may incorporate more, fewer or other elements.

Method and apparatus for setting and managing operational dynamics within cognitive radio networks

In certain embodiments of a cognitive radio, a method of establishing operational policies, involves determining that a new policy decision should be made; requesting a policy decision from an authority having more computing power than the cognitive radio; receiving the policy decision from the authority; and implementing the policy decision in the cognitive radio. Other embodiments may incorporate more, fewer or other elements.

Managing operation of a cognative radio by an authority

A method of accumulating and maintaining the accumulated data comprises steps of maintaining an intermediate count in a first memory device (12), reading a plurality of count values from a second memory device (14), determining a greatest count value of a subset of the plurality of count values which satisfy at least one criterion, and determining an updated count based upon the intermediate count and the greatest count value. The at least one criterion includes a criterion that the greatest count value differs from a second greatest count value of the subset of the plurality of count values by at most a predetermined difference greater than one. A system and a device to perform the method are detailed.

A method and corresponding apparatus for error correction of MSK-coded data receives a signal (101) partitionable into adjacent frames (111,113) each subdividable into three tridents (103, 105, 107). A first sample quality metric (225) applicable to a p (123) of the signal (101) associated with a last trident (107) of the tridents of a first frame (111) of the adjacent frames (111, 113) is synthesized, and a second sample quality metric (227) applicable to a portion (125) of the signal (101) associated with a first trident (103') of the tridents of a second frame (113) following the first frame (111) is synthesized. Each of the first and second sample quality metrics (225, 227) have a magnitude dependent on a time that the associated portion (123) of the signal (101) has a magnitude exceeding an average magnitude (127) of the signal (101). A corrected polarity (113) of the portion of the signal (101) associated with the last trident (107) of the tridents of the first frame (111) is determined dependent on a sample quality metric having a greater magnitude of the first sample quality metric (225) and the second sample quality metric (227).

A backup battery management method (200), and corresponding apparatus (101 ) monitors a system voltage (111 ) and charges a backup battery (109) while a short-term average (405) of the system voltage exceeds a long-term average (407) of the system voltage.

Adaptive backup battery management for vehicular based electronic modules

A vehicle monitoring system is described having an arrangement installed within a vehicle, wherein the system includes an external data terminal for communicating information to a remotely located base station. The arrangement includes a plurality of communication modules, each being capable of communicating messages associated with performance of the vehicle; a data bus member for electrically intercoupling the plurality of communication modules and for receiving the communicated messages therefrom; a driver interface module for transmitting messages to and for receiving messages from a vehicle operator; and a recorder coupled to the data bus member for recording information associated with performance of the vehicle which has been transmitted over the data bus member by the plurality of communication modules, coupled to the driver interface module via a second data bus member for transferring messages therebetween. The external data port is provided by the recorder and is used for communicating messages with the base station, preferably over an RF link.

Vehicle monitoring arrangement and system

In a communication system having a communication channel for transmitting data between a base station and a plurality of mobile radio units, wherein each radio unit has a unique identification (ID) code and wherein transmissions from each radio unit to the base station include the unit's ID code, a method is described for identifying which units are within RF communication proximity of the base station. The method includes: transmitting a range message, including a low ID code parameter and a high ID code parameter, from the base station over the channel to elicit a response from at least one of the mobile radio units having an ID code between the low and high parameters; determining whether radio units transmitted a message in response to the range message; and storing, responsive to transmission by the units, in an ID list a signal representative of the respective ID code assigned to such transmitting units. These steps are repeated with different transmitted range messages until each of the radio units within RF proximity of the base station is appended to the ID list.
