Title: Multi-user random access in a wireless network
Inventor: PATRICE NEZOU
IPC: H04W84/12
Filed: 2017-04-28
Abstract: In a wireless network comprising an access point and a plurality of stations, a station receives a trigger frame from the access point, the trigger frame reserving a transmission opportunity on at least one communication channel of the wireless network, the transmission opportunity including random resource units that the stations may access using a contention scheme. The trigger frame includes a first indicator specifying a traffic type of data allowed to be sent on at least one of the random resource units. The station determines, based on the first indicator, eligible resource units for the station to contend for access for transmitting data and transmits data on a determined eligible resource unit using a contention scheme. A trigger frame may also or alternatively include a second indicator indicating the stations allowed to send data on at least one random resource unit. The second indicator may be an association identifier (AID). A station may update a contention parameter based on the number of eligible resource units.

Title: Patient monitoring system
Inventor: GIDEON MATTHEW HALE
IPC: G06T7/593
Filed: 2017-05-17
Abstract: A patient monitoring system for monitoring the location of a patient at a distance comprises a projector 52 for projecting a pattern of light onto the surface of the patient and an imaging system 50 for obtaining images of the patient on to whom the pattern of light is projected. A heat sink 55 is further associated with the projector 52 and a heat source 74, such as an array of resistors, is configured to apply heat to the heat sink 55 when the projector 52 is not being operated, thus reducing the variation in the temperature of the heat sink 55. This in turn reduces variation in the thermal expansion and contraction of the monitoring system; effects which can potentially introduce source of error in determining the position of a patient. The heat source 74 may further be responsive to the output of a thermometer measuring the temperature of the heat sink 55; applying heat to the heat sink 55 when the projector is not operated so as to maintain the heat sink 55 at a constant temperature.

Title: Jet-effect and shaped tunnel
Inventor: YURI ABRAMOV
IPC: F03D80/00
Filed: 2016-06-07
Abstract: A convergent-divergent nozzle 610 is defined with a specific shape, claimed to provide linear change in Mach number, pressure, temperature or density, for more efficient acceleration of a fluid. The nozzle may be real or imaginary, defined by streamlines in the fluid flow, caused by aerofoils of limited extent. Described uses for the nozzle include propulsion for a flying saucer which does not require fuel, and systems which, in addition to producing thrust, also provide low temperature air. The nozzle is also described with powered, contra-rotating propellers for propulsion or fluid extraction. The application also describes a proposed hydrophobic jet effect produced by specifically shaped, hydrophobic bodies. Also described is a method for computational fluid dynamics which claims to be based on the kinetic theory of matter, thermodynamics, continuum mechanics, and generalized equations of fluid motion. Methods can be applied to airfoil shape optimization for bodies flying separately as well as in a cascaded sequence. Water harvesting from air is also discussed.

Title: A method of controlling a waste heat recovery system
Inventor: ALAN AGURTO GOYA
IPC: F02G5/02
Filed: 2018-05-04
Abstract: A method of controlling a Rankine cycle Waste Heat Recovery (WHR) system 14 of a vehicle 1 comprises receiving driving data comprising route data indicative of characteristics of a route along which the vehicle 1 is expected to travel. The driving data is analysed to predict properties (temperature and flow rate) of the exhaust gas from the internal combustion engine 2 while the vehicle 1 travels along the route; and the waste heat recovery system 14 is controlled based on the predicted properties of the exhaust gas. The control may determine operation of the pump or another part of the heat engine. The route date may include road gradient or trajectory, a junction or speed restriction, or meteorological conditions such as headwind. By predicting future properties of the exhaust gas, the waste heat recovery system can be controlled more efficiently.
