Abstract: A contactless biometrics monitoring system includes: a first device to transmit a modulated signal into an environment, the modulated signal being modulated to amplify one or more biometric patterns of a user located within the environment; and a second device to receive a reflection of the modulated signal off the user located within the environment. The reflection includes a vibration component, and the vibration component indicates biometric information of the user corresponding to the one or more biometric patterns amplified by the modulated signal.

Abstract: A gas feedthrough in a semiconductor processing apparatus comprises a static-dissipative composite material. This material is characterized by good resistance to electromigration and is preferably made of a homogeneous material. This apparatus for preventing the transfer of energy to a gas flown through a gas line and comprises a gas feedthrough comprising a static-dissipative material, the feedthrough having a first end for abuttingly contacting an electrically energized member and a second end for contacting a grounded member, the feedthrough defining a void therein along its length to house a gas line.
