Title: Axial ion ejection from a segmented linear ion trap
Inventor: GREEN MARTIN
IPC: H01J49/42
Filed: 2006-12-21
Abstract: An ion trap mass analyzer is disclosed comprising a segmented rod set. Ions are trapped radially within the mass analyzer by a radial pseudo-potential well. The ions are also confined axially within the ion trap by an axial electric field. The axial electric field is substantially linear across the central section of the ion trap, i.e. has a quadratic potential profile, but the electric field is distorted across both ends of the ion trap (see Figures 7 & 12). A supplemental AC voltage or potential is applied to the electrodes comprising the ion trap mass analyser in order to resonantly or parametrically excite ions within the ion trap 1. The distortions in the electric field at the ends of the ion trap cause the resonant frequency of ions within the ion trap to shift to either a higher or lower frequency (see Figures 8, 10, 13 & 15). If the frequency of the supplemental AC voltage or potential is scanned appropriately then ions are ejected from the ion trap in a shorter/longer period of time leading to an improvement in mass resolution (see Figures 9,11,14 & 16).

Title: Real current circuit protection device
Inventor: JACKSON KEITH
IPC: G01R19/06
Filed: 2007-10-02
Abstract: An electrical circuit protection device has a digital signal processor that receives a digital signal Idig representing current through an electrical supply path and a digital signal Vdig representing the voltage and, based on these signals, produces a digital signal IRdig which represents the real component of the current. The signals can be used to produce digital values representing: root mean squared (RMS) values of voltage and current; apparent current; real and apparent power; power factor and phase angle, using a square function, infinite impulse response filtering and a square root function. The protection device can operate a trip (fig 2, 18) using an interrupt signal INT when a threshold value is exceeded. It can take the form of a residual current circuit breaker (RCCB) whereupon the current signal is a current imbalance detected by a toroid transformer and the form of a miniature circuit breaker (MCB) in which the signal represents the current through an electrical supply. The protection device can therefore respond to real values of fault current that are likely to cause fires and electrocution, while discriminating from a less dangerous reactive fault current caused by suppression capacitors.

Title: Trust anchor key cryptogram and cryptoperiod management method
Inventor: MOREAU THIERRY
IPC: H04L9/08
Filed: 2006-06-22
Abstract: In the field of public key cryptography, e.g. a public key infrastructure, the distribution of trust anchor keys to end-user systems is difficult when the time comes to change the public key, either because a compromise of the private key counterpart is suspected, or as a cryptoperiod policy enforcement. With the present invention, the central organization (from which the trust anchor key originates) is given the opportunity to distribute at once a number of trust anchor keys, in advance of their respective intended period of use, and without exposing the individual public keys to brute force attacks before their actual period of use. At a later time, the central organization distributes unlocking information that enables the use of a public key distributed according to the present invention. The preferred embodiment makes use of an hidden selection of a cryptographic function among a function family.

The data of a control chart (52) with the measured values of a first and second temperature sensor 41, 42 are used in order to establish the control parameters for the temperature regulation. In the procedure for the initialization, commissioning and operation of a measuring device, the state of the device is interrogated in a sequence of steps and an identifier 86 on the test sample holder 35 is read out. The control parameters for the phases of the measurement are ascertained from the measured values of a first and second temperature sensor 41, 42, the values of the control chart (52) and the identifier 86 of the test sample holder 35 and are then converted by the temperature-regulating unit 53 in the course of the measurement.
