Title: EMF impact triggered reporting and cell selection
Inventor: YIWEI FANG
IPC: H04W36/24
Filed: 2015-10-21
Abstract: A UE (10) in a wireless communication network reports measurements or selects cells based on the EMF exposure to one or more persons in those cells, estimated to result on the uplink (UL) and/or downlink (DL) due to the UE's use of those cells. Thenetwork sends indications to the UE, in order to allow the UE to understand the EMF impact generated when the UE is connected to certain cells. For the downlink, these indications may include an EMF impact indicator or a UL beamforming reception capability indicator. For application to LTE, a new event triggered UE measurement reporting criterion is proposed to allow the UE to report measurements based on a new EMF related metric and to trigger measurement reports with regards to the EMF impact. The new EMF-based measurement reports allow the cell selection/ reselection process to take into account minimization or optimization of the EMF impact on the environment.

Title: Polymeric proteins and uses thereof
Inventor: Richard Pleass
IPC: C07K16/46
Filed: 2015-07-20
Abstract: Provided are polymeric proteins that comprise two or more polypeptide monomer units, each monomer unit comprising two chimeric protein chains. Each chimeric polypeptide monomer unit comprises an Fc receptor binding portion comprising two immunoglobulin G heavy chain constant regions,wherein each immunoglobulin G heavy chain constant region comprises a cysteine residue which is linked via a disulfide bond to a cysteine residue of an immunoglobulin G heavy chain constant region of an adjacent polypeptide monomer unit. Each chimeric protein chain also comprises a modified immunoglobulin M tailpiece region, wherein the amino acid sequence of each chimeric polypeptide monomer comprises an alteration of the primary structure as compared to the native sequences from which the immunoglobulin G heavy chain constant region or immunoglobulin M tailpiece region are derived, and the alteration changes the number of glycosylation sites in a manner that promotes polymerisation. This promotion of polymerisation may lead to the generation of tetrameric, hexameric, and even dodecameric forms of the proteins. The proteins are suitable formedical uses,such as in the prevention or treatment of autoimmune diseases such as idiopathic thrombocytopenia. Also provided are methods of treatment using the polymeric proteins, and pharmaceutical compositions comprising the polymeric proteins.

Title: Passive entry passive start (PEPS) system with relay attack prevention
Inventor: RIAD GHABRA
IPC: G07C9/00
Filed: 2016-02-17
Abstract: A remote control unit 12, such as a fob, communicates with a base station 14 at a target, such as a vehicle. The control unit and the base station are configured to communicate authorization signals and time-of-flight (ToF) ranging signals concurrently between one another. The base station confirms from the authorization signals whether the control unit is authorized for controlling a target function and to confirm from the ToF ranging signals whether the control unit is within range of the target. The base station prevents the target function, such as door opening or engine start, from being controlled by the control unit when the control unit is not within range of the target. The ToF ranging signals are ultra wide band (UWB) signals 42 and the authorisation signals are low frequency (LF) 38 signals and ultra-high frequency (UHF) signals 40. Wake-up signals can be transmitted from the base station to the control unit when user interaction such as a door handle touch 34 or a button touch 36 is detected. Different microcontrollers are used in the base station for ranging and authorisation. The use of time of flight ranging signals prevents relay attacks.
