Abstract: A multi-leaf collimator can comprise two banks of leaves facing each other across the radiation field, and an actuation member or actuation means configured to control the location of each leaf, for example, to control the degree to which each leaf is extended into the radiation field. The leaves of the multi-leaf collimator can comprise at least one radioluminescent marker that can emit illumination light, which can be used to accurately determine the position of the leaves.

Abstract: An antenna apparatus can include a coaxial cable with one end of the coaxial cable forming a remote antenna and the other end of the coaxial cable comprising a local coupler, wherein both ends of the coaxial cable are over-molded protection in a water meter installation. The local coupler can snap-on to a communications module and is operable across wideband RF frequencies ranging from, for example, 790 MHz to 1900 MHz. The antenna apparatus may also be implemented with an alternative RF coupler design, with two metal planes secured by an IP68 plastic housing with the provision of the coaxial cable to interface with a coupler and the remote antenna. The coupler can operate with low losses of less than, for example, 10 dB. In addition, the remote antenna can be installed on a water pit lid and in some cases, the coaxial cable itself can act as a remote antenna.

Abstract: A wireless signal transmitter is provided for a radiotherapy device, said radiotherapy device being configured to provide radiation to a subject via a source of radiation, and further being configured to output a non-continuous beam of radiation, wherein said non-continuous beam of radiation has a first, time-related property associated therewith. The wireless signal transmitter is configured to wirelessly transmit a signal comprising data regarding the first, time-related property that is associated with the non-continuous beam of radiation, to a wireless signal receiver.

Abstract: A method of controlling a radiotherapy device, a computer readable medium and a radiotherapy device are disclosed. The radiotherapy device includes a radiation source coupled to a rotation means. The method includes applying radiation to a subject using the radiation source and rotating the radiation source around the subject using the rotation means according to a first fixed rotation scheme. The method further includes, during execution of the first fixed rotation scheme, determining that the subject is in a suboptimal position, pausing application of the radiation by the radiation source and logging a first angle of rotation of the radiation source at which application of the radiation is paused.

Abstract: An apparatus for permitting a flying vehicle to land on or take off therefrom whilst the apparatus is airborne, the apparatus including: a surface for supporting the flying vehicle during landing or when taking off; at least one propulsion device for sustaining flight of the apparatus and for positioning the surface in a desired landing or taking off orientation; and a link which is connectable at one end to a land- or sea-going vehicle, for tethering the apparatus relative thereto.

Abstract: A positive displacement fluid flow meter that may have a rotary piston that rotates inside a chamber as a fluid flows through it. The rotating piston may create fixed volume discrete parcels from the passing fluid. The piston may be buoyant relative to the fluid flowing through the meter. Buoyancy of the piston may reduce friction and noise in the meter to result in a more accurate fluid flow measuring meter.

Abstract: A method and system for achieving a link budget improvement in a diverse OFDM radio system by addressing the timing misalignment issue that can occur due to the differences in propagation time in signals between mobile stations and Radio Access Nodes. Timing misalignment is shared or split between the primary path to a primary Radio Access Node and a diverse path to a diverse Radio Access Node. The relative timing offsets between mobile stations are adjusted, the mobile stations are grouped into zones using a variety of different grouping techniques, and the transmission for each mobile station is scheduled, using one or more of a variety of scheduling techniques.

Abstract: A caliper comprising: (a) an inboard side; (b) an outward side, wherein the inboard side and the outboard side include three or more bores that are radially staggered relative to two or more of the bores; and (c) a pocket located within a central region of the inboard side, the outboard side, or both; wherein the bores on the inboard side, the outboard side, or both are positioned so that: (i) all of the bores are located entirely radially below the pocket; (ii) none of the bores are located below the pocket; (iii) one or more of the bores are located partially radially below the pocket; (iv) one or more of the bores are located entirely radially below the pocket; (v) one or more of the bores are not located partially or entirely radially below the pocket; or (vi) a combination of (iii) through (v).
