摘要： This invention discloses a combined-screen-based multi-pitching angle suspended panoramic space 3D display device comprising: a combined deflective diffusing screen, a high speed projector, an image control module, a rotation detecting module, a motor and a drive mechanism. The high speed projector projects the composite images of the 3D objects of different pitching angles and horizontal 360° FOV to different areas of the combined deflective diffusing screen. Each area of the combined deflective diffusing screen controls the deflecting angle and the scattering angle in the vertical direction and the diffusing angle in the horizontal direction, ensuring that the eyes of the surrounding viewers of different height levels can see the 3D images corresponding to their respective positions, representing the 3D scene suspended over the combined deflective diffusing screen.

摘要： Channel power management may be achieved in a branched optical communication system such that uniform loading is provided across branch channels on a branch drop path without passing information signals that are not intended for the branch terminal to the branch drop path. In general, a system and method consistent with the present disclosure reuses one or more loading signals (e.g., noise bands) from the branch add path to maintain uniform loading in the branch drop path of the same branch. The system and method thus prevents trunk channels from being dropped to a branch terminal when those trunk channels are not intended for the branch terminal.

摘要： Apparatus and methods enable robust, reliable control for implantable medical devices, including cardiac pacemakers, defibrillators and cardiac resynchronization devices. Integrated circuits in the devices have minimized interfaces, can derive power from the interface signals, and have high voltage and latch-up protection. A device lead has a power generation circuit and a switching circuit using cascaded PMOS transistors for operating with a stable voltage despite fluctuations in the supplied voltage. The lead has control electronics that provide a very low impedance between an electrode and a lead conductor during most of the duration of a pacing pulse, but during a brief initial portion of the pacing pulse, provide a very high impedance to permit charging up a power supply that is local to the control electronics. A method of stabilizing the external impedance and a system for fault detection and fault recovery for an implantable device are also provided.
