Abstract: A user of a client can access an application using privileged credentials without having direct access to or knowledge of the privileged credentials. The user's access to the application can also be monitored using a custom protocol including recording the user's interactions with the application while logged in with the privileged credentials.

Abstract: There is disclosed a capacitive touch pad or device (10) which includes a substrate (12) and a plurality of capacilive pads (18) at an inner surface (16) of the substrate (12). Each pad (18) is provided with a local oscillator (22), the oscillation frequency of which varies with the capacitance of the capacitive pad (18). A micro controller (26) is operable to sense the oscillation frequency of the oscillators (22). In order to be usable in humid and wet environments, the microcontroller (26)operates on the basis of a time averaged signal from each of the oscillators (22) and compares this to a threshold, which threshold in the preferred embodiment is variable, for instance by time-averaging. The oscillators (22) is preferably close to the capacitive pads (18) in order to allow the use of a thicker substrate (12) and in the preferred embodiment a substrate which is waterproof. These arrangements provide a capacitive touch sensor device which can be used in humid or wet conditions.

Abstract: A method of recovering hydrocarbon substances such as oil and tar from naturally occurring mineral matter such as oil shale and young coal ranks, which comprises subjecting the natural mineral product to microwave irradiation in a pressure vessel through which an expelling medium is passed. The expelling medium can be gaseous or liquefied carbon dioxide containing natural or mixed gases, hydrocarbon-containing gas, vapor or liquid and gaseous or vapor-halogenated hydrocarbons.
