Abstract: A control apparatus for a satellite comprises a command generator to generate TT&C instructions for the satellite. The control apparatus further comprises an encryptor to encrypt TT&C instructions using a common quantum encryption key shared with the satellite and a transmitter to transmit the encrypted TT&C instructions to the satellite. A satellite comprises a command and telemetry subsystem to generate TT&C information for the satellite. The satellite further comprises an encryptor to encrypt TT&C instructions using a common quantum encryption key shared with the control apparatus and a transmitter to transmit the encrypted TT&C instructions to the control apparatus.

Abstract: The invention relates to a glove for making goniometric measures, i.e. angular measurements, of a wearer's hand and a method of manufacture of the same. The glove is adapted for use in the assessment of ahnad mobility in medical applications and is particularly useful for misshaped hands. The glove comprises a palmar panel with finger sections extending short of the distal interphalangeal joint and preferably proximal to the distal interphalangeal joint.
