Abstract: The present embodiments provide a brace which includes an actuator. The actuator provides movement of the arm and shoulder, abduction movement, so that during recovery from shoulder surgery, the shoulder and arm movement may be supported in increased range of motion positions. This may be done with a single brace rather than requiring multiple braces during the recovery process.

Abstract: A signal for use on a wired network interconnecting electronic devices, comprising: a base voltage for conveying power to the electronic devices; a pulsed voltage signal bearing coded information for transfer between the electronic devices; and a digital signal superimposed onto selected portions of the pulsed voltage signal, wherein the digital signal comprises a carrier signal modulated by a data signal for transfer between the electronic devices. This is used in fire alarm networks, for example, to convey multimedia or other data such as control signals, whilst maintaining compatibility with existing protocols using the pulsed voltage signal.

This is used in fire alarm networks, for example, to convey multimedia or other data such as control signals, whilst maintaining compatibility with existing protocols using the pulsed voltage signal.
