Title: Supercharger with vaned diffuser
Inventor: DON LEE
IPC: F04D29/46
Filed: 2016-12-15
Abstract: An electric supercharger comprising an electric motor and a radial flow compressor assembly 1 is disclosed. The radial flow compressor assembly comprises a compressor wheel 11 rotatable on a drive-shaft 6 driven by the motor. Air flows from an inlet 3 through the compressor, a volute 4 and then to an outlet 5. A diffuser 9, comprising a plurality of movable vanes 7, is positioned between the compressor and the volute. The vanes are movable between an open configuration, allowing air to flow through to the volute, and a closed position. Closing the vanes provides a barrier to stop air flow through the supercharger. This may hermetically seal the supercharger if it bypassed, improving efficiency and negating any reduction in the effect of a turbocharger in a twin charging arrangement. Apparatus for supplying a compressed air charge to an internal combustion engine and a method of using said apparatus are also disclosed.

Title: A computer data encoding system
Inventor: PHILIP MICHAEL GAFFNEY
IPC: G06F21/62
Filed: 2016-12-16
Abstract: A computer data encoding system (100, fig 1) includes an intermediate computer system 103 that is configured to: receive an encrypted data string from an electronic device 107; substitute a unique encoded string for the encrypted data string; send the encoded string to a data storage computer system 104; send the encoded string to the electronic device 107; and store a map (which may be encrypted) of the encoded string assigned to the encrypted string substituted for the encrypted data string. An electronic device for use in a computer data encoding system obtains and decodes an encoded and encrypted data string by obtaining an encoded string from a data storage computer system; interrogating a map of the encoded string to an encrypted data string to find an encrypted data string that is mapped to the encoded string; and decrypting the encrypted data string. The map maybe encrypted using a key stored at an encryption key storage computer system that has no access to the data storage computer system. System allows fields of personally identifiable information PII to be protected by tagging or marking the fields to indicate to the intermediate processing device that these fields should be encoded.

Title: Safety trapped key interlock system
Inventor: WAYNE HODGSON
IPC: E05B29/00
Filed: 2016-06-10
Abstract: A trapped key interlock system is disclosed. A pair of hollow tubular casings located one inside the other and each having a series of elongate slots are used. When the lock is in a locked condition the elongate slots are aligned as inner and outer pairs with engaging members extending through the pairs of slots is preventing rotational movement of the tubular casings relative to each other. The engaging members are biased towards this locked condition. On insertion of the correctly coded key the engaging members are caused to move against the biasing force out of engagement with the slots in the outer tubular casing thereby allowing the inner tubular casing to rotate relative to the outer tubular casing and moving the lock to an unlocked condition.

Title: Controlling vehicle platooning
Inventor: TOM MIZUTANI
IPC: G05D1/02
Filed: 2018-03-23
Abstract: A distributed vehicle platooning system comprises a core layer including a central server 300; an edge (middle) layer comprising local cell servers (e.g. cellular base transceiver stations (BTS)); and a vehicle layer comprising vehicles 100. A vehicle platooning controller (106, Fig.1) transmits a journey constraint to the central server to enable generation of cell constraints; receives platoon-in-cell information dependent on the cell constraints from respective local cell servers during the journey; and controls vehicle speed, direction or platoon position in dependence on the platoon-in-cell information. The journey constraint may be a destination, arrival time, starting time or current location and may be confidential. The cell constraints may be speed profiles or inter-vehicle distances and may depend on route conditions (e.g. traffic, weather, road or road elevation). The platoon-in-cell information may be a speed profile, inter-vehicle distance or platoon position and may have a finer level of detail than the cell constraints and vary throughout the cell.

Title: Vehicle ice strike prediction
Inventor: MAHMOUD YOUSEF GHANNAM
IPC: G08G1/16
Filed: 2018-05-16
Abstract: A first vehicle 100 identifies a second vehicle 200 based on first vehicle sensor 130 data. Wherein a processor on the first vehicle determines, based on at least one of the sensor data and additional environmental data, a risk of ice 230 from the second vehicle striking the first vehicle. The processor causes an action in the first vehicle based on the determined risk. The action may be changing a driving lane (e.g. 210a to 210b) or may be closing a protective cover of the vehicle sensor to limit the damage caused by an ice strike. In determining the risk of ice detaching and falling from the preceding vehicle the trajectory 240d of the ice may be estimated and may also include determining whether the vehicle ahead has travelled from a snowy area based on weather data.
