  • Publication number: 20120237555
    Abstract: A solid substrate coating capable of swelling by a factor of at least 2 on contact with an aqueous solution. The solid substrate coating may be prepared by activating the surface of a solid substrate by treatment with a plasma, depositing a first layer of siloxane onto the surface of the solid substrate using plasma, and depositing a second layer of at least on chemical functionality on top of the first layer using plasma.

  • Patent number: 8242789
    Abstract: A plasma system (1) has a circuit including a DC source (6), a power supply line (9), an electrodes (2, 3), and a return line (18). A perturbation signal source (8) delivers a perturbation signal into the circuit in addition to DC voltage from the DC source (6). Acquisition (10) and analysis (11) systems measure response to the perturbation. The analysis system (11) measures variation in impedance of the circuit and phase between voltage and current in the circuit. It also uses a frequency domain reflectrometry technique to measure signal reflection modulus of a supply line of the circuit over a defined frequency range.

  • Patent number: 6441620
    Abstract: A method of fault identification in a plasma process powered by an RF source comprises initially determining, in respect of a given baseline plasma process, the changes in magnitude of a plurality of Fourier components of the RF source resulting from changes in a plurality of the process input parameters from their baseline values. These magnitude changes are stored as reference data. During a subsequent production run, the plasma process is monitored for faults and if one is found the baseline process is repeated with input parameter values nominally the same as the original baseline values. The changes in the Fourier components from the original baseline values are determined and compared with the reference data to determine which input parameter(s) have changed.

  • Patent number: 4290432
    Abstract: A decompression bubble detector comprises a pulsed ultra-sound transmitter/receiver which is scanned across a cross-section of tissue and the total number of pulse echoes received in a preselected time interval is recorded. Changes in the total number of pulse echoes recorded in successive time intervals are used to monitor the decompression. A single transducer is scanned by means of a driven eccentric cam and a cam follower. A sin/cos potentiometer generates a signal related to the angular position of the transducer connected to a delay so that pulse counting can be arranged to coincide with the passage of the transducer across the target.
