Abstract: A demodulation sensor (30) is described for detecting and demodulating a modulated radiation field impinging on a substrate (31). The sensor comprises the means (1,7,15) for generating, in the substrate, a static majority current assisted drift (Edrift) field, at least one gate structure (33) for collecting and accumulating minority carriers (21), the minority carriers generated in the substrate by the impinging radiation (28) field. The at least one gate structure comprises at least two regions (4,9,18) for the collection and accumulation of the minority carriers (21) and at least one gate (5,6,8) adapted for inducing a lateral electric drift field under the gate structure, the system thus being adapted for directing the minority carriers (21) towards one of the at least two regions (4,9) under influence of the static majority current assisted drift field and the lateral electric drift field induced by the at least one gate, and a means for reading out the accumulated minority carriers in that region.

Abstract: A sensor package comprises an active element with a first region and an opposite second region. The first region includes a sensing structure. The second region comprises at least one contact pad. A moulding compound encapsulates the second region and not the first region. The active element comprises at least one conductive line for routing signals from the sensing structure to the contact pad. The projection of the conductive line over the active element corresponds to a portion of the external surface of the active element. The active element comprises at least one dummy track providing a protrusion thereby raising a portion of the surface of the active element to at least the same height as the portion corresponding to the conductive line. These protrusions can receive mechanical pressure from a moulding insert applied during manufacture, relieving pressure over the portion of the surface including the conductive lines.

Abstract: An indirect time of flight range calculation apparatus comprises a light source, a photonic mixer that generates a plurality of output signals corresponding to a first plurality of phase values. A signal processor is also provided to calculate a first vector and a first angle from the first vector. The photonic mixer generates a second plurality of electrical output signals corresponding to a second plurality of phase values. Each phase value of the second plurality of phase values is respectively offset with respect to each phase value of the first plurality of phase values by a predetermined phase offset value. The signal processor processes the second plurality of electrical output signals in order to calculate a second vector, and de-rotates the second vector calculated and calculates a second angle from the de-rotated vector before offsetting the second angle against the first angle, thereby generating a corrected output angle.

Abstract: A unit trench capacitor in a substrate includes one or more trenches in the substrate, a dielectric layer, a first electrode and a second electrode. Walls of the one or more trenches are covered by the dielectric layer which separates the first electrode from the second electrode. Each trench follows a closed curve. The closed curve of each trench has one or more elongated parts in directions in which the substrate has a maximum elastic modulus, or the closed curve of each trench has a circular shape if the substrate has an isotropic elastic modulus.

The method includes interchanging a data frame including a bit sequence, between a master control unit and at least one of a plurality of driving units at slave nodes. The method includes applying an ID field for addressing at least one driving unit, and applying a data field comprising information and/or instructions regarding the status of the electronic units. Applying the ID field comprises indicating the driving unit address using a first bit sub-string comprising N bits, allowing the master control unit to identify whether data should be received or transmitted, performing a data length decoding step, and adding a further bit string to the data field including information for carrying out an action by the driving unit.
