Title: Secure method of providing a delivery address during a tokenised transaction
Inventor: Sunil Peenikal
IPC: G06Q20/38
Filed: 2016-06-30
Abstract: The present invention relates to a secure method of providing a delivery address during a tokenised payment transaction scheme. A consumer 10 places an order with a merchant 20 without providing a delivery address. A distributor 40 that collects payments due to the merchant requests a payment identification code and a delivery address from a payment agent 50. The request includes payment information. The payment agent generates and stores a payment identification code along with the payment information, and sends the code to the consumer via the distributor. The consumer forwards the code to a financial institution 30 for forwarding to the payment agent who returns the payment information along with a request for a delivery address. The consumer may respond by authorising the payment and by providing a delivery address. The financial institution then arranges the payment to the merchant and sees that the merchant receives the delivery address. A method where the consumer requests the code and passes the code to the payee is also provided.

Title: Display system
Inventor: ALEXANDER COLE
IPC: G03H1/26
Filed: 2017-08-25
Abstract: A holographic display system and a method of adjusting a holographic display system are disclosed. A first plurality of pixels (for example, upon a first spatial light modulator/SLM) is arranged to display a first hologram, receive light of a first wavelength from light source 603, and output spatially-modulated light according to the first hologram, along a first optical path 609. A first Fourier transform lens on the first optical path forms a first holographic reconstruction at a replay plane 650. A second plurality of pixels (for example, upon a second spatial light modulator/SLM) is arranged to display a second hologram, receive light of a second wavelength, and output spatially modulated light according to the second hologram, along a second optical path (which may be collinear with the first optical path 609). The holograms may be computer-generated. A second Fourier transform lens on the second optical path forms a second holographic reconstruction at the replay plane. A first optical element 607b on the first optical path is arranged to receive the output light from a first part of the first optical path and direct it along a second part 609b of the first optical path to the replay plane 650. A second optical element 617g on the second optical path is arranged to receive the output light of the second wavelength from a first part of the second optical path and direct it along a second part (609g) of the second optical path to the replay plane 650. The length of the first part of the first optical path is not equal to the length of the first part of the second optical path. The first part of the first optical path may be substantially collinear with the first part of the second optical path. A third plurality of pixels (for example, upon a third spatial light modulator/SLM) may also be incorporated and arranged to display a third hologram to spatially modulate received light of a third wavelength, the spatially modulated light passing through a third Fourier transform lens and via a third optical element 627r to form a third holographic reconstruction at the replay plane 650. The optical elements may be wavelength-selective mirrors, for example dichroic mirrors. The wavelengths may correspond to Red, Green and Blue light to form a multicolour holographic reconstruction at the replay plane representing a sequence of video frames. The method for adjusting the holographic display system involves adjusting the position of the mirrors such that the size and resolution of the respective holographic reconstructions are substantially the same at the replay plane.

IPC: A63B6/00
Filed: 2017-10-12
Abstract: A support structure for a human or animal body comprises a support layer (14, fig.2) and an array of resilient upstanding members 12 arranged over an area of the support layer. The resilient members are formed such that they resist an applied load by reversibly collapsing in a direction towards the support layer. Each member may resist a load by first being compressed up to a first loading threshold, and then undergoing reversible collapse. Each member may be in the form of a hollow tube. A feature such as a notch or groove may be formed part way along the length of the resilient member in order to promote collapse at that point. The resilient members soften upon repeated collapsing in response to cyclic loading. Each resilient member may collapse independently of other resilient members in the array. A method of customising a user support by repeatedly loading the support structure is also disclosed. The support structure may be used as a mechanical sensor to record a loading profile.

Title: Turbogenerator method
Inventor: Michela Mascherin
IPC: H02P9/08
Filed: 2018-03-21
Abstract: A turbogenerator system comprises a generator, a turbine configured to rotate within said generator, and power electronics. The turbogenerator system is initialised by providing electrical power to the power electronics, detecting a condition of the grid or the power electronics and limiting the rotational speed of the turbine within the generator to a first predetermined setpoint speed. The rotational speed of the turbine is allowed to increase above the first predetermined to reach a second predetermined setpoint speed when it is determined that the grid or the power electronics is in a condition suitable to receive electrical power. The generated electrical power is then exported to the grid. The method seeks to prevent damage to the generator due to overspeed, particularly in a black start situation when the grid is unavailable, or a “fast start” scenario when the generator is required to rapidly move from idle to full power operation, or when a combination of both is required. The turbogenerator may be used as part of an energy recovery system, particularly where a turbine is placed within the exhaust gas of a prime mover.
