    摘要： An apparatus and methods for delivering ocular implants or microimplants. The apparatus is ergonomically designed for ease of use, and a simple manual depression of an actuator produces proportional movement of a linkage causing the implant or microimplant to be ejected through a cannula disposed at the desired location in the eye. Small gauge cannulas are provided for self-sealing methods of delivery.

    摘要： Particles emitted by radio-isotopic by-products of nuclear fission are used as a power source at the cathode of a magnetron system. Particles include high energy electrons having a large associated EMF. In the system a radial electrical vector E, between the cathode and anode, interacts with an axial magnetic vector B vector to produce an E×B force that rotates the particles about the system axis. These emissions are within a set range of velocities. The angular velocity and geometry of a rotating field, known as a space charge wheel (SCW), may be modulated by an external RF inputs to cavities of an anode block and the use of concentric biasing grids between the cathode and anode block. The SCW induces LC values into cavities of the anode, exciting them and producing electrons resonance which may be used to generate power.

    摘要： Multiple power amplifiers in an RF front end are coupled to multiple antennas without diversity switching between the PAs and antennas. Diversity switches direct signals to broadcast by a selected antenna to a PA coupled to the selected antenna. Multiple LNAs are similarly coupled to the diverse antennas. Having one PA and LNA set for each antenna removes the need for diversity switching between the PA/LNAs and each antenna improving signal reception. In one embodiment, a single external PA performs broadcast functions and plural on-chip LNAs are used for reception. In another embodiment, phase shifters are coupled to each PA and LNA, which provide beam forming capability for broadcasts, and in phase signal combinations for received signals.
