  • Patent number: 9344983
    Abstract: Systems and methods for adaptive OTA (over-the-air) synchronization of RF (radio frequency) base stations are described herein. Using these systems and methods, base stations in wireless audio systems can automatically identify externally sourced base station clocks and merge overlapping clock system domains, thereby eliminating the need for complex base station management and network configuration.
    Type: Grant

  • Patent number: 8573195
    Abstract: The present invention provides a process for absorbing solar energy and, simultaneously having a continuous control of the light admission making it possible to install the device in external openings of buildings and equipment, such as windows, shutters or skylights. The system comprises two frames which support plates of transparent material, between which it is possible to introduce a colourful solution coming from an external reservoir. Both frames are interconnected through a flexible membrane which allows the plates to be pushed against each other, making the window transparent, or pushed away interposing the colourful solution, which will make the window uniform and gradually translucent or opaque. The said liquid comes from a reservoir and the access to the gap between the plates through is obtained by means of a channel that separates the two frames, allowing the liquid to flow evenly into the whole surface, thus being a homogenous and adjustable darkening obtainable.

  • Publication number: 20080202837
    Abstract: This invention refers to a wheelchair control system which enables them to move in an omnidirectional way without much effort by its user. The system is made up of a base (1) where the wheels and motors are attached (2) the batteries (3). The necessary electronics to the full functioning of the wheelchair are located on the second level (4). On the next level up, is placed the processing unit (5). Over all this structure is placed the wheelchair seat (6). On its arm is mounted a joystick (or other wheelchair controlling device) (7) as well as a digital screen (8) so that the user can write and read the all the wheelchair information. The processing unit on board can also receive information from sensors located all around the wheelchair to automatically avoid obstacles. Additionally, this wheelchair control system is electrically fed through rechargeable batteries or fuel cells (3), offering great usage autonomy.
