Abstract: A mass spectrometer includes a main magnet having spaced-apart polepieces which define a gap, the main magnet producing a magnetic field in the gap, an ion source to generate ions and to accelerate the ions into the magnetic field in the gap, the ion source located outside the gap, and an ion detector to detect a selected species of the ions generated by the ion source and deflected by the magnetic field. The ion detector is located in the gap at a natural focus point of the selected species of ions. The mass spectrometer may be used in a trace gas leak detector.

Abstract: A communication system is disclosed including at least a communication network, one caller party equipped with a communication device by using of which the caller party may originate a communication, one called party equipped with communication means by using of which the called party may response to the communication originated by the caller party and one or more network elements arranged in communication network for arranging the communication between the caller and called parties and which of network elements at least part are arranged to be operated as VoIP system elements in order to arrange VoIP-based communication. In communication system is arranged to be implemented as features a protocol enabling an availability of a presence information of at least the communication means of the called party and an universal designation feature in order to form a destination address for the communication from the caller party to the called party.

Abstract: Methods and apparatus for large leak testing are provided. The apparatus includes a test line to receive a sample containing a trace gas, a mass spectrometer to detect the trace gas and having an inlet for receiving the trace gas, a first vacuum pump characterized by a relatively high reverse flow rate for light gases and a relatively low reverse flow rate for heavy gases, the first vacuum pump having a pump inlet and a foreline, the pump inlet being coupled to the inlet of the mass spectrometer, and a second vacuum pump configured to back the first vacuum pump. The apparatus further includes a trace gas permeable member coupled between the test line and the pump inlet, the foreline, or, in the case where the first vacuum pump is a turbomolecular pump, a midstage line.

Abstract: The present invention relates to a mobile node, router device and method of providing to a first type of traffic an enhanced handover function specified for a second type of traffic, wherein a predetermined set of handover destination address parameters is derived from a protocol signaling related to the second type of traffic. This derived set of handover destination address parameters is then used to generate for the first type of traffic a new destination address in accordance with the second type of traffic, and a binding update is initiated for binding at least one original destination address of the first type of traffic to the generated new destination address of the second type of traffic. Thus, handover support can be provided for the first kind of traffic without requiring a dedicated handover protocol for the first kind of traffic.

Abstract: Methods and apparatus are provided for detection of large leaks in scaled articles. Apparatus for leak detection includes a first sealable chamber configured to receive a test piece containing a trace gas, a second sealable chamber, a first valve coupled between the first and second chambers, a leak detector having a test port, a trace gas permeable member coupled between the second chamber and the test port of the leak detector, a vacuum pump having an inlet, and a second valve coupled between the second chamber and the inlet of the vacuum pump. The permeable member may be quartz, which is permeable to helium when heated. The leak detector may be an ion pump or a helium mass spectrometer leak detector.

Abstract: A digital “baton” is provided from a firewall or other gateway, or other network device, to a device B outside the firewall, when a device A, which is inside the firewall, requests information from the device B. The device B may pass the digital baton to subsequent electronic devices that may respond to the request using the digital baton to send messages or information through the firewall to the device A. The firewall authenticates and filters the messages based on authentication of the batons contained within the messages.

Abstract: Methods and apparatus are provided for leak detection by the accumulation method. The apparatus includes a sealable chamber (10) configured to receive a test piece (12) that, while in the chamber, contains a trace gas, a trace gas permeable member (30) in gas communication with the chamber, and a trace gas sensor (20) in gas communication with the permeable member and configured to sense the trace gas that passed from the chamber through the permeable member. The permeable member may be quartz. The trace gas sensor may include an ion pump.

Abstract: An apparatus for a residential low voltage control system. A low voltage controller is adapted to fit into a standard wiring box, and the controller provides isolation/separation of the low voltage wiring from other wiring. The face plate of the controller, in one embodiment, has a recessed portion with terminals for connecting the low voltage conductors. In another embodiment, the face plate has a recessed portion with an opening for a terminal block to protrude. In still another embodiment, the face plate has an opening for a low profile terminal block to protrude.

Abstract: An ion pump includes one or more anode pump cells, a cathode positioned in proximity to the one or more anode pump cells and a magnet assembly for producing a magnetic field in the one or more anode pump cells. An electric field is applied between the cathode and the one or more anode pump cells. The magnet assembly includes primary magnets of opposite polarities disposed on opposite ends of the anode pump cells and secondary magnets disposed on opposite sides of the anode pump cells. The magnet assembly may further include a magnet yoke which provides a magnetic flux return path. The magnet assembly produces a substantially uniform axial magnetic field in the one or more anode pump cells.
