Abstract: A wireless transmit/receive unit (WTRU) may receive a constellation symbol that includes indications that each are associated with a respective WTRU of a plurality of WTRUs. The WTRU may determine that a first weight associated with a first indication of the indications is different than a second weight associated with a second indication of the indications. The indications may comprise indications of bits modulated at a multi-user constellation bit division multiple access modulator (MU-CBDMAM).

Abstract: Mechanisms may be used for aggregating acknowledgement (ACK), block ACK (BA) and/or short packets transmissions for multi-user (MU) wireless communication systems. Aggregation mechanisms may be used for uplink (UL) and/or downlink (DL) orthogonal frequency division multiple access (OFDMA), and/or UL/DL multiple-user multiple input multiple output (MU-MIMO) transmissions, for example. Multi-user short packets may be aggregated and/or simultaneously transmitted for DL, UL, or peer-to-peer (P2P) transmissions.

Abstract: The invention provides a method for generating a training set of data for training a classifier relating to a physiological condition. The method begins by obtaining a first set of data relating to a first plurality of subjects and a second set of data relating to a second plurality of subjects, wherein each of the first set of data and the second set of data are grouped into a plurality of subsets of data, wherein the plurality of subsets of data is associated with a plurality of features. Descriptive statistics are calculated for each of the plurality of subsets of data within the first set of data and one or more features within the plurality of features is selected based on the calculated descriptive statistics to generate a search criterion. A supplementary set of data is identified from the second set of data by applying the search criterion to the second set of data. The training data set is then compiled based on the first set of data and the supplementary set of data.

Abstract: A system and method is provided for monitoring the fetal position and/or orientation of the fetus of an expectant mother. An acoustic sensor array is positioned over the belly. The pattern of acoustic sensor signals is processed to determine a fetal orientation and/or to determine movement over time of the fetus.

Abstract: A muscle imaging system that uses an ultrasound probe to image one or more muscles of a subject. A processing unit controls a driving mechanism to set a position of the ultrasound probe with respect to the subject. A position of the ultrasound probe, during an imaging process, is at least partly based upon a shape of the subject detected by a shape sensor.

Abstract: A rehabilitation device is for monitoring hand movement of a user in which one or both forearms are supported on a forearm support region of a support, and an upward facing camera is mounted with a field of view forwards beyond the front of the forearm support to capture an image of the hand or hands, which extend in front of the forearm support region. This avoids the need for the user to wear a sensor glove but also enables a compact system without needing an overhead camera or a large table arrangement.

Abstract: A method and an apparatus for locating a fault cause are provided. The method includes: obtaining parameter values of a plurality of running parameters and a parameter value of a fault parameter in preset duration before a wavelength division multiplexing board device is faulty; determining a correlation between each of the plurality of running parameters and the fault parameter; and determining at least one target parameter from the plurality of running parameters based on a value of the correlation, where a correlation between each of the at least one target parameter and the fault parameter is greater than a correlation between the fault parameter and a running parameter other than the at least one target parameter in the plurality of running parameters. Accuracy of locating a fault cause can be improved in the embodiments of the present disclosure.

Abstract: Systems, methods, and devices are disclosed for determining a beam modulation mode and/or a carrier modulation mode. A beamformed reference signal may be transmitted to a wireless transmit/receive unit (WTRU). A beam measurement report may be received from the WTRU. The beam measurement report may include a beam modulation mode recommendation and/or a carrier modulation mode recommendation. A beam modulation mode and/or a carrier modulation mode may be determined based on a mode recommendation. A beam modulation mode and/or a carrier modulation mode may indicate a manner of transmitting same information on multiple beams.

The indications may comprise indications of bits modulated at a multi-user constellation bit division multiple access modulator (MU-CBDMAM).

Abstract: A device is provided for monitoring the delivery and taking of medication pills by detecting both the passage of a pill and the covering of a pill outlet region, which is indicative of an active operation of the user to remove the pill from the pill outlet region. In this way, pill delivery can be monitored as well as an indication of actual pill taking.

Abstract: The present invention provides a method and apparatus for tracking hand and/or wrist rotation of a user performing exercise. An aspect of the present invention proposes a method of tracking hand and/or wrist rotation of a user performing an exercise, wherein the user wears a marker on his/her hand, the method comprising the steps of: acquiring a first image and a second image of the marker by means of a camera when the hand is in a first posture and a second posture respectively; deriving the angle change of the hand and/or wrist from the change from the first posture to the second posture, based on the first image and the second image and the type of the exercise that the user is performing; and outputting the angle change of the hand and/or wrist, wherein the marker approximates a rectangular block, the marker has an opening for accommodating the palm(s) of the user and the side of the marker along the direction perpendicular to the palm is substantially shorter than two other sides.
