Abstract: A modular lifting apparatus that can be assembled about an item to be lifted such as a pallet has at least two elongate bars 10 connected and spaced apart by at least two spacers 20 and at least four end plates 30 that are fitted to ends of the elongate bars 10 using a locking mechanism. Each elongate bar 10 passes through or under an item to be lifted and projects from each end of the item to be lifted; each spacer 20 is shaped and dimensioned to have a portion (21 fig. 3D) that extends to abut the item to be lifted and prevent the spacer 20 moving along the elongate bars 10, and the spacer 20 has a pair of eyes 22, each eye receives an end of an elongate bar 10. End plates 30 fix the spacers 20 in position once fitted to the elongate bars 10. Each end plate 30 includes a means for engaging with a lifting device such as an aperture 33 or a lip or a textured surface (34 fig. 4C). End plates 30 may be fitted to the elongate bars 10 using a twist lock mechanism comprising a key (31 fig. 4C) on each end plate 30 and an opening (11 fig. 2D) at the end of each elongate bar 10.

Title: Synchronisation signals
Inventor: BERTRAND MUQUET
IPC: H04W56/00
Filed: 2019-02-13
Abstract: A UE in a cellular communications network connected using a first Radio Access Technology (RAT) may utilise synchronisation signals from a second RAT to re-synchronise with the first radio access technology. Base stations for the first and second radio access technologies may be co-located, and synchronised in time and frequency. Information to enable decoding of the synchronisation signal may be transmitted via the first or second radio access technology. Preferably, the first RAT is Narrowband Internet of Things (NB-IoT), and the second RAT is Cat-M. A ReSynchroisation Signal (RSS) has been defined in the standards to assist Cat-M devices in quickly synchronizing with a serving cell. However, implementing an RSS signal in NB-IoT consumes too many radio resources to be practical. An embodiment describes an NB-IoT base station transmitting parameters to enable the UE to receive an RSS signal transmitted by a Cat-M base station. Full details of the Cat-M transmission may not be required, but only selected details.

Title: Method and System for determining eye test screen distance
Inventor: PETER ESTIBEIRO
IPC: A61B3/032
Filed: 2021-11-01
Abstract: A computer-implemented method of determining a distance from a display, e.g., a computer display, to a user’s eye includes estimating, using a first technique, a distance between a display and a user’s eye and repeatedly estimating, using a second technique, different to the first, a distance between the display and the user’s eye. The first measurement may be direct, such as with a tape. The second measurement may be by displaying a first symbol or target 172 and encouraging a user to focus on that and displaying a second target 174 in the user’s peripheral vision. The targets are moved, 176, relative to each other until the second target disappears in the natural retinal blind spot which the user indicates 178. Average spacing of fovea and blind spot may be used to calculate the distance to the display. Alternatively, facial landmarks may be used for the second measurement. The dimensions and spacing of the targets may be initially set by the first measurement. The distance measurement may be used to set the size of symbols for a visual acuity test and repeat distance measurements ensure reliability.
