Abstract: Method and system for method for communicating between a device and a server, the method comprising the steps of the server initiating device wake-up. Obtaining generic bootstrapping architecture, GBA, push information, GPI, including security credentials or information used to derive the security credentials. Sending a device wake-up message to the device, wherein the device a wake-up message includes the GPI. Authenticating the security credentials within the GPI to obtain a key.

Abstract: A compound comprising a cyclopentanone, cyclopentenone, cyclohexanone or cyclohexenone group, wherein a first ring carbon atom carries an —SR substituent, R is a substituted or unsubstituted alkyl, alkenyl, alkynyl, aryl, aralkyl, aralkenyl, or aralkynyl group that, optionally, includes at least one heteroatom in its carbon skeleton, the remaining available ring carbon atoms are optionally substituted, and said compound either:—(a) is more soluble in water at a temperature of 20-40° C.; (b) is less lipophilic; and/or, (c) has a greater therapeutic index; or; (d) is less soluble in water at a temperature of 20-40° C.; (e) is more lipophilic; and/or, (f) has a greater therapeutic index; than an equivalent cyclohex-2-en-1-one or cyclopent-2-en-1-one derivative in which a hydrogen atom replaces said —SR group.

Abstract: A control device manages an electronically actuated device for the purpose of ejecting liquids onto a substrate in a controlled manner (i.e. a print head). This device will be used in parallel with other similar control devices also controlling print heads. The operation of more than one of these devices in parallel will constitute a single printer control system. This printer control system will normally be managed by an external computer system to cause individual print heads controlled by the print head controllers and operating under the direction of the external computer system to digitally place fluids onto appropriate substrates and at high speed. Each print element is responsible for printing a swathe of print representing a strip through the original image. This swathe is aligned very precisely such that each adjacent strip aligns precisely with its neighbors.
