  • Publication number: 20130264948
    Abstract: The present invention relates to a lighting control system, comprising a control unit comprising a memory in which control programs are recorded. The control programs are capable of controlling the optical transmission through an active window pane with electro-controllable optical transmission properties and are capable of controlling an electro-controllable lighting device. The system furthermore comprises a coloration sensor for measuring a value representative of a coloration of the light. The control programs are capable of controlling the lighting generated by the lighting device as a function of the value supplied by the coloration sensor.

  • Publication number: 20130258484
    Abstract: The present invention relates to a system for controlling the optical transmission of a plurality of windows Vk with electro-controllable optical transmission properties, comprising at least one spatial brightness sensor for supplying at least one value representative of brightness respectively for different spatial areas forming subsets Xi of a set X and thus supplying a mapping L of a brightness in which the subsets Li of L are associated with the sets Xi, and a control unit comprising a memory in which programs are stored which are capable of controlling the optical transmission of each of said windows.

  • Patent number: 7204843
    Abstract: A surgical instrument for anastomosis of first and second blood vessels includes a housing having distal and proximal ends, a handle and a disposable loading unit removably mounted to the distal end of the housing. The loading unit includes upper and lower fastener support members having a passage defined therethrough for receiving an end of the second blood vessel and configured to releasably support a plurality of surgical fasteners. The loading unit also includes a retractable anvil located at a distal end of the loading unit, the anvil being movable relative to the fastener support member in response to actuation of the handle to simultaneously deform the of surgical fasteners.

  • Patent number: 4053695
    Abstract: A sealed lead acid cell is disclosed which has electrodes comprising metallic supports which minimize the evolution of hydrogen and resist deformation under their own weight, and which are separated by at least one layer of separator material, the capacity of the negative electrodes is arranged to be at least as great as the capacity of the positive electrodes, the thickness of the electrodes is less than 3mm, the thickness of the separator is in the range of 10 to 200% of the thickness of the electrodes, and the volume, E, of electrolyte in the cell in relation to the sum of the pore volume of the separators, X, and the pore volume of the positive and negative active materials, Y, is not greater than 2X + Y.
