  • Publication number: 20240138776
    Abstract: Systems, methods, apparatuses, and computer program products for non-invasive glucose monitoring. A method may include continuously capturing a photoplethysmography signal of a patient in real-time. The method may also include inputting a blood pressure measurement, demographic information, and the photoplethysmography signal into a mobile application. The method may further include transmitting, as input information, the blood pressure measurement, the demographic information, and the photoplethysmography signal to a cloud server. In addition, the method may include generating, based on the input information, a glucose prediction of the patient.

  • Patent number: 8792577
    Abstract: Method and apparatus for medium access control in a wireless broadband system with multiuser MIMO/MISO technology comprising the steps of a transmitter (Tx) broadcasting a polling message (1) to all the users (Rx1 . . . Rxi . . . RXN) associated to said transmitter (Tx); the users answering with reply messages (2) during a time slot (61 . . . 6m) randomly selected from a plurality of time slots in which a period of time dedicated to sending reply messages (5) is divided; the transmitter (Tx) performing a scheduling and transmission of data (3); and scheduled users sending Acknowledgment messages (4). Preferably, only users which measure a Signal to Noise plus Interference Ratio over a pre-defined threshold for a transmission beam send reply messages (2).

  • Patent number: 8441932
    Abstract: Method of efficiently allocating a downlink channel from a transmitter (1) to one user selected from a plurality of users (30-1, 30-2, . . . 30-N) in a wireless network providing different service applications to said users (30-1, 30-2, . . . 30-N), which comprises the steps of: at a DLC queue (221) of said transmitter (1), ranking (21, 220) a plurality of M application layer packets to be transmitted to said plurality of users (30-1, 30-2, . . . 30-N), said ranking being based on a quality of service demand associated to each application layer packet, said quality of service demands being in turn associated to respective classes of applications (C1, C2, C3, C4), said DLC queue (221) having length M, M being a natural number, said M packets corresponding to P users of said plurality of users (30-1, 30-2, . . . 30-N), wherein P?M.

  • Patent number: 8310980
    Abstract: Method for assigning a precoding beam forming scheme in a broadband satellite system, wherein said broadband satellite system comprises a multibeam satellite (1) having a plurality of antennas and a plurality of satellite beams, a gateway (2) and a number N of satellite terminals (ST11, ST12 . . . ST21, ST22, ST23 . . . STK1, STK2 . . . ), and wherein said gateway (2) is configured for processing and serving a plurality of K beams of said plurality of satellite beams towards said number N of satellite terminals (ST11, ST12 . . . ST21, ST22, ST23 . . . STK1, STK2 . . . ), wherein K<N, and wherein said assignation of a precoding beam forming scheme comprises a joint processing over said plurality of K beams. Said precoding beam forming scheme is dependent: on the radiation pattern of said satellite antennas; on the line of sight channel characteristics and on the multiuser diversity caused by said number N of satellite terminals (ST11, ST12 . . . ST21, ST22, ST23 . . . STK1, STK2 . . . ).

  • Patent number: 8208952
    Abstract: Method for allocating a minimum downlink power from a transmitter (1) having nt transmit antennas of a cellular multi-user multi-antenna communications system with N users attached to said transmitter (1). Each user comprises at least one antenna. The method comprising the steps of: generating at said transmitter (1) M random beams (b1 . . . bM); sending said M random beams through all the transmit antennas; calculating at each user a signal-to-noise-interference-ratio for each random beam sent by said transmitter (1); sending back to said transmitter (1) said calculated values of signal-to-noise-interference-ratio, said signal-to-noise-interference-ratio representing a partial channel state information; selecting at said transmitter (1) the M best users which correspond to the M best values of signal-to-noise-interference-ratio per beam.
