摘要:
A modulation technique for 3D time-of-flight (TOF) cameras allows the operation of fully autonomous operated 3D TOF cameras. The method subdivides the exposure time into several sub-exposure intervals, for which the signal control unit adds a preferably pseudo-random common phase delay to the illumination and the sensor.

A method to compensate for multi-path in time-of-flight (TOF) three dimensional (3D) cameras applies different modulation frequencies in order to calculate/estimate the error vector. Multi-path in 3D TOF cameras might be caused by one of the two following sources: stray light artifacts in the TOF camera systems and multiple reflections in the scene. The proposed method compensates for the errors caused by both sources by implementing multiple modulation frequencies.

摘要:
A flat fluorescent light (1), comprises a discharge vessel that is composed of a based plate (3), face plate (4) and frame (5). A contact system (2) for connecting an electric power supply device by connection lines is integrated into the narrow side of the flat fluorescent light. An insulation body, provided with U-shaped contact sections is located between a section of the base plate (3) and face plate (4), the section acting as a receptacle and projecting beyond the frame (5) of the discharge vessel. The contact surface of the contact sections are connected to the electrodes of the flat florescent light by connection surfaces of the receptacle. The connection parts of the contact sections are connected to the connection lines.
摘要:
The present invention is directed to a method and apparatus for bending and cutting outboard terminals, or leads, of surface mountable integrated modules applied to a carrier frame wherein slots are cut in the carrier frame so that retaining webs remain between the slots and the circuit modules. Each of the retaining webs interconnects the outboard terminals along one side of the circuit module to stabilize the terminals during a subsequent bending of the leads. A combination cutting and bending die is moved downward to cut the retaining webs free from one another and to bend the leads into their desired shape. The retaining webs and any excess length of the outboard terminals is then trimmed off, all while the circuit module is held in a hold-down part so that no stresses are transferred to the chip module during bending.

The invention relates to retroviral vectors (known as lentiviral vectors), which are used to transfer genes into cells that are at cell cycle stage G0, to methods for their production and to the use thereof for transferring genes into mammalian cells. Said vectors are derived from SIVsmmPBj14 (simian immunodeficiency virus) of the sooty mangabey monkey, strain PBj 14.
摘要:
The invention relates to a method for producing a conductive contact part for a detachable electric plug-in connection. Said method provides a contact element comprising a bushing part, sections of which contain longitudinal slits and which has ribs distributed around its periphery. A sleeve part, which can surround the bushing part and cover the ribs, comprises two opposing end faces. The sleeve part is placed and positioned in an approximately coaxial manner in relation to the bushing part, in such a way that it covers the ribs, the positioned sleeve part being locked by one of its two faces on the bushing part. The bushing part is elastically twisted about its central axis, in such a way that the ribs are towards said central axis and the other face of the sleeve part is locked on the bushing part that is held in a twisted position against the elastic restoring force of the ribs. A contact part, designed for mass-reduction, with defined elastic properties of the ribs can thus be produced in a reproducible manner.
