Abstract: Disclosed are barrier coatings for fused silica components used in semiconductor processing. In particular, the present disclosure concerns protective substrate-barrier coatings composed of corrosion-resilient metal compounds which provide superior resistance to erosion/corrosion when a coated substrate is subjected to the acidic environments at elevated temperatures typical for semiconductor processing.

Abstract: A patient controlled analgesia device generally includes: a patient controlled analgesia pump and a biometric authentication system. The biometric authentication system generally includes a biometric pump controller coupled to the patient controlled analgesia pump that activates the patient controlled analgesia pump to deliver analgesia and a biometric switch adapted to receive a biometric input and operably coupled to the biometric pump controller to activate the biometric pump controller. A biometric authentication processor in the biometric pump controller activates the patient controlled analgesia pump to deliver analgesia only upon authenticating the biometric input received at the biometric switch. Optionally, the biometric pump controller also includes a dosing processor that limits delivery of analgesia according to a prescription.

Abstract: A method of controlling traction in a vehicle having at least one non-driven wheel speed sensor. Actual vehicle acceleration and a wheel speed difference are detected. At least one of the actual vehicle acceleration and the wheel speed difference is compared to at least one of a predetermined vehicle acceleration and a predetermined wheel speed difference to detect vehicle wheel slip. A wheel torque is reduced in response to detected wheel slip. The foregoing method allows traction control to be installed in many types of vehicles, including vehicles without ABS. More than one type of wheel slip detection can be implemented, and various types of wheel slip can be detected.
