Abstract: Embodiments disclose a method for determining a payload platform configuration. The method involves receiving platform specifications, receiving payload specifications for a first payload and a second payload, and receiving operational constraints for a vehicle to which the platform and the second payload will be attached, the operational constraints being based on payload specifications for the first payload. The method involves using finite element analysis and/or dynamic load analysis to generate predictions about operational performance of the vehicle and corresponding properties of the platform, the predictions being based on payload specifications for the second payload.

Abstract: A combination of a GPS device and an adjacent mobile communications device. The mobile communications device comprises: a wireless communications transceiver comprising means for receiving at least one of timing information and location information. The GPS device comprises: a receiver for receiving at least one GPS signal, a positional estimator for providing a positional estimate in dependence of said received at least one GPS signal and said at least one of timing information and location information.

Abstract: A method and system for assaying P2Y receptors. The method allows for direct detection of ligand binding events with a high signal to noise ratio. The ability to quantify binding events involving the P2Y receptor has heretofore been unavailable due to unavoidable non-selective binding of a radioligand or other traditional probes. A cell-free system for the study of P2Y receptors including a P2Y receptor; optionally, a protein that is normally associated with the P2Y receptor in nature; and a vesicle, is also disclosed.
