Abstract: Disclosed is a system provided with a vibration device and cooling fluid for interstitial laser therapy. Use of the vibration device to vibrate at least part of the system releases and assists in the transfer of gas bubbles (e.g. steam) produced during treatment use, thus stabilising the temperature at or near a treatment site. The system for interstitial laser therapy includes an optical waveguide having an optical output end and an associated optical diffuser, an irrigation tube, an outer tube (e.g. cannula) and a vibration device. The irrigation tube directs cooling fluid to flow out of a distal end of the irrigation tube which directs cooling fluid to flow inside of and/or outside of the optical diffuser. The vibration device is used to vibrate the irrigation tube, the optical diffuser and/or the outer tube.

Abstract: An inductive power transfer receiver. The receiver comprising an inductive power input circuit comprising a tuning circuit with a receiver coil, and a power control circuit for controlling the output power.

The power control circuit comprises at least one variable reactance component that can be varied to control the output power provided to the load.

Abstract: Approaches are described for a decentralized computing platform that enables dynamic execution of distributed services through a hybrid on-chain and off-chain architecture. The platform consists of a network of nodes, each running a virtual machine to host and execute service instances. A sequencer component records, sequences, and notarizes function calls to maintain a consistent service-level state across the network. Computation takes place off-chain on nodes that participate dynamically in specific services based on resource availability. A persistent virtual memory structure manages both service-level and instance-level state. The service-level state is synchronized across nodes participating in the same service, while the instance-level state is isolated to individual nodes for independent operations. The memory system is non-volatile, retaining state across function calls and enabling direct execution from memory.
