Abstract: A multilateration method basically includes receiving a signal strength indicator for at least one client wireless device from a plurality of access point devices, and calculating a position of the at least one client wireless device based on the signal strength indicator for the at least one client wireless device, prestored positions of the access point devices and a radio transmission parameter. The radio transmission parameter is obtained as a value that minimizes an error between a calculated position of at least one reference wireless device and a prestored position of the at least one reference wireless device.

Abstract: Method for controlling a dynamic linear motor. Method includes defining a path over which a rotor is to travel, placing stator segments at least along portions of the path where the rotor may be one of accelerated and decelerated and supplying a variable amplitude and frequency of voltage to power the stator segments in a synchronized manner so that, as the rotor approaches stator segments, the stator segments are powered and, as the rotor departs stator segments, the stator segments are depowered.

Abstract: Methods and systems are disclosed for real-time calculation of rewards associated with a commercial transaction. A real-time calculation of rewards can be associated with card payment transactions occurring on a payment account. In an aspect, a customer swiping their bank card at a merchant point of sale to initiate an authorization for a purchase can trigger notification and deliver of rewards associated with the pending commercial transaction.

Abstract: A dynamic linear motor is controlled by determining a relative proximity of a moving rotor of the linear motor to a fixed stator segment of the linear motor using a current location of the moving rotor. A current driving characteristic of the linear motor at the current location of the moving rotor is determined. Settings for the fixed stator segment when the moving rotor reaches the fixed stator segment are identified based on the current driving characteristic. The fixed stator segment is driven based on the settings when the moving rotor reaches the fixed stator segment.

Abstract: A system includes a first mobile device and a second mobile device. The first mobile device has access to staging data of a network relay server. The second mobile device is precluded from connecting to the network relay server. The second mobile device is configured to connect to the first mobile device. The first mobile device is configured as a mobile relay server for transmitting the staging data to the second mobile device.

Abstract: The present invention provides an isolated polypeptide, designated Beta R1, whose production is selectively induced by IFN-&bgr; as compared to IFN-&agr;. The Beta R1 polypeptide is a chemokine whose expression is stimulated in T cells, astrocytes, and fibroblasts that have been—exposed to IFN-&bgr;. The present invention also provides an isolated polynucleotide that encodes the Beta R1 polypeptide and an isolated polynucleotide that encodes the Beta R1 promoter. The present invention also provides a method of identifying putative IFN-&bgr; mimics. In one embodiment, the method comprises the steps of providing cultured cells transfected with a polynucleotide construct that comprises a DNA sequence that encodes the Beta R1 promoter operatively linked to a reporter gene that encodes an assayable product; treating the transfected cells with the putative IFN-&bgr; mimic; and detecting the assayable product produced by the treated cells.

Abstract: The invention provides a chemokine designated Beta R1, whose production in T cells, astrocytes, a fibroblasts is preferentially induced by IFN-.beta. as compared to IFN-.alpha.. A cDNA encoding the Beta R1 polypeptide and comprising the endogenous Beta R1 promoter is described. When coupled to a reporter gene, the promoter sequence may be used to screen for mimics of IFN-.beta. activity.
