IPC: H01L27/32
Filed: 2002-11-01
Abstract: In a matrix-addressable optoelectronic apparatus comprising a functional medium in the form of an optoelectronically active material (3) provided in a global layer in sandwich between a first and second electrode means (EMl,EM2) with parallel strip-like electrodes (1; 2) wherein the electrodes (2) of the second electrode means (EM2) are oriented at an angle to the electrodes (1) of the first electrode means (EM2), functional elements (5) are formed in the active material where respective electrodes (1, 2) overlap and correspond to optically active pixels (5) in a display device or pixels (5) in an optical detector, depending upon the active material (3) used. In each of the electrode means (EM1; EM2) the electrodes (1; 2) are provided in a dense parallel configuration and mutually insulated by a thin film (6) with a thickness that is only a fraction of the width of the electrodes. This allows for a fill factor of pixels (5) in the active material (3) approaching unity and a corresponding high degree of pixellation, thus providing either a display with a high surface brightness and high resolution or an optical detector with high sensitivity and high resolution.

IPC: H04L47/80
Filed: 2002-03-28
Abstract: The present invention relates to a method an arrangement for reserving resources in an IP network. By mixing open-ended reservations with in-advance reservations, by utilising a common pool of resources, the resource utilisation will be high. Despite the support for open-ended reservations, the present invention allows immediate and in-advance time-limited reservations wherein the resources are guaranteed. It also allows modification of active and "soon to be active" reservations, which in turn permit soft-state reservations. The invention supports different types of applications with varying time-distributions and varying risk of pre-emption. A new concept of open-ended in-advance reservations is also introduced in the present invention.
