A privacy display comprises a polarised output spatial light modulator, reflective polariser, plural polar control retarders and a polariser. In a privacy mode of operation, on-axis light from the spatial light modulator is directed without loss, whereas off-axis light has reduced luminance. Further, display reflectivity is reduced for on-axis reflections of ambient light, while reflectivity is increased for off-axis light. The visibility of the display to off-axis snoopers is reduced by means of luminance reduction and increased frontal reflectivity to ambient light. In a public mode of operation, the liquid crystal retardance is adjusted so that off-axis luminance and reflectivity are unmodified.

A medical ad hoc wireless network (10) is deployed in a healthcare facility around an individual patient, comprising wireless nodes (A, B, . . . , Z). Prior to deployment, each node (A, B, . . . , Z) is pre-initialized with public key certificates (22) and provides trust and symmetric key distribution services (32). Nodes (B) joining the ad hoc network (10) authenticate and register a random self-selected node (A) by using the authenticated public key (20). Such a node (A) becomes the trust portal (TPA) of the node (B). Node (B) dynamically registers a new self-selected TP node when its old TP node leaves the ad hoc network (10). The network (10) supports symmetric key authentication between nodes registered to the same TP node. Furthermore, it supports symmetric key authentication between nodes registered to different TP nodes.
