Abstract: Systems and methods include directing limited frequencies of microwave signals toward target molecules, driving a motion of the target molecules to impact molecular recognition. In one implementation, a microwave spectra associated with the rotational modes of a target molecule is obtained. From peaks in the spectra, a mode of molecular movement is identified and a microwave signal profile is generated for driving a motion of binding portions of the molecule associated with the identified mode. Microwave signals are generated based on the signal profile for output by antennas. For example, the microwave signals can be can be used to impede the binding of quorum sensing molecules by receptors of P. aeruginosa. In one implementation, the antennas can be placed in a catheter for placement in a patient. In another implementation, the antennas can be placed in a sleeve or other device for use adjacent to the skin of a patient.

Abstract: The Invention is directed to a mobile communications system having improved spectral efficiency. The invention is further directed to methods and apparatus to achieve this improved spectral efficiency. In the mobile communications system communication with a plurality of mobile terminals is provided by a base station. Within the system terminals are adapted to communicate with one or more adjacent similar terminals to establish groups of terminals, called micro-cells. Each terminal within a micro-cell receives signals from the base station and then performs a first processing step on these signals. These processed signals are shared with all the other terminals within the micro-cell. Each terminal then performs a second processing step on the information it has received from all the other terminals within the micro-cell which enables it to derive a signal intended for reception by that terminal.

Abstract: A video controller for synchronizing presentation of a plurality of images is provided. A color switching device is operable to continually select a color out of a set consisting essentially of a plurality of fundamental colors.

Abstract: According to the invention, a safety device for a pre-filled syringe comprises a hollow support body for mounting the pre-filled syringe therein, a hollow needle shield that is slidable relative to the support body and guiding means for guiding the movement of the needle shield relative to the support body. The guiding means comprise a flexible arm with a guide pin, a guide track and a separating wall. The guide pin extends from the flexible arm in a radial direction, and protrudes into the guide track. The separating wall extends into the guide track in a direction parallel to a central axis of the safety device. When the needle shield is slid relative to the support body the guide pin moves along the guide track to deflect the flexible arm in a lateral direction perpendicular to the central axis and the movement of the guide pin along the guide track is guided by the interplay of the flexible arm and the separating wall.

Abstract: A system and method for improving stereoscopic images produced by a projecting device containing a single chip DMD, seen through an eye-switching device, such as a pair of liquid crystal (LC) shutter glasses. The system and method are used with a video projector used with a multiple-color, color switching device The color switching device produces Blue, Red and Green lights and at least one non-critical segment. A color sequencing firmware resident in the video projector is used to align a non-critical segment in front of the projector's main light source during the eye-switching device's unstable transition phase. If the non-critical segment is transmissive, the firmware controls the DMD so light is discontinued. If the non-critical segment is non-transmissive, light is physically blocked. If the non-critical segment is electronically defined, the firmware directly controls the DMD to discontinue the transmission of light for the duration of device's unstable transition phase.
