Abstract: The present invention is directed to an information management system (“IMS”) which utilizes delegated control (FIG. 1) over a dataset to overcome a number of the problems associated with existing IMSs. Delegated control is the transfer, generally temporary, of at least partial control over the dataset (50) from a delegating system (100) to a delegate system (200). The delegating system has full control of the dataset, but declines to exercise that authority in regard to at least a portion of the dataset while authority over that portion of the dataset is delegated. Thus, any dataset modification request received from a reqestor (300) system that wants to modify the dataset, and is not the delegate or delegator, will be refused.

Abstract: Content based routing and broadcasting methods and devices (10) utilizing routers (100) programmed to analyze the non-address portion (701) of data packets (700) and to route the packets (700) accordingly are described as are their application in support of blind broadcasting.

Abstract: A resource (35) is recruited by a negotiation between two independent computers (10, 30). The computers (10, 30) are preferably at a significant distance from one another, and likely not part of the same local area network. The negotiation may be based on any condition or combination of conditions, including monetary or other compensation, a subject matter to which the resource (35) will be applied, a percent of avaibility of the resource (35) at the providing computer (30). The negotiation may also be based upon value, a recent value, a reliability value, a type of work value, or a compensation value. The negotiation may be facilitated by one of the computers (10, 30) listing either a need or an available resource (35) on a directory (22).

Abstract: The present invention is directed to an apparatus and method of increasing the sensitivity of a magnetic sensor embedded in a key fob used in passive keyless entry and identification systems. The sensitivity of the sensor is increased by magnetically coupling a pair of magnetic flux concentrators at opposite ends of the magnetic core of the sensor, which is surrounded by a helical conductive coil. Addition of the magnetic flux concentrators external to the coil effectively forces a larger window of magnetic flux through the coil than was possible without them. This increases the magnetic sensitivity of the coil as a sensor in a time varying magnetic field. In a key fob/passive keyless device this results in an increased range of operation.

Abstract: An intelligent signal switch/detector is used in a wireless transponder device fabricated in an integrated circuit package so that dc offset bias need not be a factor in determining the no signal logic level to an input of a digital microcontroller. Direct current components from the transponder receiver amplifier are ignored and only the received alternating current signal information is passed on to a logic circuit to be processed. The intelligent signal switch/detector comprises a circuit such as a monostable which is triggered by a rising edge from an output of the transponder receiver amplifier. The edge triggered circuit then generates a pulse(s) that is input to the logic circuit. The width of the pulse may be adjusted for different applications.

Abstract: A modulated input signal is filtered to reduce noise. The state of the input signal controls the state of a switch. Depending upon its state, the switch connects one of two circuits to a gate. The gate receives the input signal and it passes or blocks the signal depending upon the state of the signal received from the switched circuits. When it is passing the input signal, the output of the gate is equivalent to the input signal. When it is blocking the input signal, the output of the gate is set to a default state. The default state is independent of the input signal. One of the switched circuits gradually modifies the signal provided by the gate to allow the input signal to pass through. The other switched circuit gradually modifies the signal provided to the gate to block the input signal.
