Title: A twin indicator with a pair of deformable bodies connected via a deformable intermediate link
Inventor: ALBERTUS ABRAHAM PETRUS GROOT DE
IPC: B60B3/16
Filed: 2018-05-18
Abstract: A device for indicating the loosening of wheel nuts/bolts and for counteracting the loosening of the nuts/bolts comprising two pairs of bodies 2 having a indicator 3 and grooved toothed bore 4 for engaging with the nut/bolt, wherein the bodies are joined by an intermediate link 5. In use the bodies are mounted to two adjacent wheel mounting nuts/bolts. When a nut/bolt loosens, the link is deformed allowing at least one body mounted to the loosening nut/bolt to rotate with the nut/bolt, rotating the indicator 3 until a predefined loosening angle 8 relative to the starting position has been reached. If the nut/bolt is still rotating e.g. unscrewing, the body mounted to the nut/bolt will deform resulting in the nut/bolt slipping/ratcheting or the like inside the body, whilst the loosening torque of the nut/bolt is higher than the counterforce 9 of the link that pulls the body back in an anti-loosening direction 11. The deformation of the body maintains the position indicator 3 at the predefined loosening angle 8 and prevents the link from breaking. Preferably the device is made from polyethylene (PE), low density polyethylene (LDPE) or linear low density polyethylene (LLDPE).

Title: Network slicing
Inventor: MATTHEW IAN RONALD WILLIAMS
IPC: H04W88/14
Filed: 2020-11-04
Abstract: Network slicing allows a network operator to divide up their network into different network slices. The operator can assign specific users or classes of users to each slice. Network functions (NFs) comprising a network slice may be placed in different locations in a network (for example, nearer the network edge), may be configured or tuned for different traffic profiles, and/or may be implemented by different vendors from those in other slices. A network, configured to perform network slicing, receives information from a Session Management Function, SMF, relating to a given packet data session belonging to a given network slice. Based on the signalling information received from the SMF, the network signals to a UPF instance that the given packet data session belongs to the given network slice. Multi-slice UPF instances are introduced.

Title: Rule-based filtering for securing password login
Inventor: Nir Rozenbaum
IPC: G06F21/31
Filed: 2021-10-01
Abstract: A password is input on a user device 310. If characters need removing from the input password 320, then the characters are removed using stored filtering rules to form a filtered password 330. The filtered password is compared to a stored password. If the filtered password matches the stored password 340, the user is allowed to log in 350. The password has characters removed if it is longer than the stored password. The filtering rules may be stored when the user opts into the filtering system. The filtering rules may identify a specific character to remove, or a regular expression that determines the characters to remove. The filtering rules may define a start and end character of a sequence of characters to remove. The filtering rules may remove a sequence of digits that add up to a predefined sum.
