  • Publication number: 20240171241
    Abstract: A method 1700 is performed by a baseband unit (BBU) 104 for scaling beamforming weights (BFWs) to assist a Radio Unit (RU) 102 with beamforming. The method includes obtaining 1702 a plurality of frequency-domain BFWs for beamforming of a number of downlink data streams in frequency-domain to be transmitted to at least one wireless device via a plurality of antennas. The BBU scales 1704 the plurality of frequency-domain BFWs based on at least one scaling factor and compresses 1706 the plurality of scaled frequency-domain BFWs. The BBU transmits 1708, to the RU, the scaled frequency-domain BFWs that have been compressed. The BBU also determines 1710 at least one user plane scaling factor for frequency-domain user plane IQ data, scales 1712 the frequency-domain user plane IQ data based on the user plane scaling factors, and transmits 1714 the scaled frequency-domain user plane IQ data to the RU.

  • Publication number: 20070282362
    Abstract: A sampler device for extraction, collection and delivery of a blood sample, includes a lancet (50) carried by a piston (40) which is movable in a cylinder (30), a mechanism (60,70) arranged to drive the piston for expelling of the lancet out from the cylinder in the distal direction and subsequently for retraction of the piston and lancet in a proximal direction, opposite to the distal direction, the cylinder being arranged for collection of the blood sample and the piston being controllable by the mechanism to travel in the distal direction upon feeding a sample volume out from the cylinder.

  • Patent number: 6411380
    Abstract: The present invention relates generally to a detection device for a spectrophotometer system, and in particular to a light detection device with an analogue input and a digital output. The object of the present invention is to provide a more accurate detection device, which requires substantially less space for accommodating the detection device in a spectrophotometer. This object is solved by using a successive approximation A/D converter (16) which has internal sample and hold circuits, and which heretofore has been used in the audio industry. This will increase the accuracy of the detection device and make it more resistant against disturbances. It will also decrease the space required for such detection device, down to one third compared to conventional detection devices.

  • Patent number: 6236986
    Abstract: The present invention relates to a method and a device for extracting information from a database, which comprises a plurality of data records, each data record comprising at least two data elements, each data element being defined by a data element type and a data element value. First, the data records are read into the primary memory of a computer, so that all processing of the data may be done off-line. Then, the data element values are binary-coded and stored in one or more tables. When the selection of at least one data element value is detected, all binary-coded data element values are examined to obtain all data records implied by selection. Due to the binary-coding, these data records are found very quickly. Finally the data element values implied by the selection is kept track of in a status set.
