A pedestrian protection system is mounted in the front portion of a vehicle, and includes a controller, a forward movement holding mechanism controlled in actuation by the controller, and a contact body that a pedestrian can contact. The controller, when having predicted a collision of a pedestrian with the vehicle based on a signal from a collision predicting sensor, actuates the forward movement holding mechanism to cause a forward movement of the contact body, and based on a signal from a turn sensor when the forward movement holding mechanism carries out an upward rotation or a downward rotation at the time of contact of the forwardly moved contact body with a pedestrian, controls actuation of the restraint body so as to correspond to a pedestrian moving to a front upper side of the vehicle and a pedestrian moving to a front lower side of the vehicle, respectively.

The present invention is directed to a method and device to desorb an analyte using heat to allow desorption of the analyte molecules, where the desorbed analyte molecules are ionized with ambient temperature ionizing species. In various embodiments of the invention a current is passed through a mesh upon which the analyte molecules are present.

An adjustable, low mass-to-charge (m/z) filter is disclosed employing electrospray ionization to block ions associated with unwanted low m/z species from entering the mass spectrometer and contributing their space charge to down-stream ion accumulation steps. The low-mass filter is made by using an adjustable potential energy barrier from the conductance limiting terminal electrode of an electrodynamic ion funnel, which prohibits species with higher ion mobilities from being transmitted. The filter provides a linear voltage adjustment of low-mass filtering from m/z values from about 50 to about 500. Mass filtering above m/z 500 can also be performed; however, higher m/z species are attenuated. The mass filter was evaluated with a liquid chromatography-mass spectrometry analysis of an albumin tryptic digest and resulted in the ability to block low-mass, “background” ions which account for 40-70% of the total ion current from the ESI source during peak elution.

The invention relates to a generating technology, in particular to a multi-stage jet-type reaction force disc generating system which mainly comprises a leak-off pipe, a jet-type reaction force disc generating set and a disc shell. The generating system is characterized in that the multi-stage jet-type reaction force disc generating set is arranged on a plurality of sections of the leak-off pipes which are connected.

A radio-frequency ion guide (20) for converging ions by a radio-frequency electric field and simultaneously transporting the ions into the subsequent stage is composed of eight rod electrodes (21 through 28) arranged in such a manner as to surround an ion optical axis (C). Each of the rod electrodes (21 through 28) is disposed at a tilt with respect to the ion optical axis (C) so that the radius r2 of the inscribed circle (29b) at the end face of the ion exit side is larger than the radius r1 of the inscribed circle (29a) at the end face of the ion injection side. Accordingly, the gradient of the magnitude or depth of the pseudopotential is formed in the ion's traveling direction in the space surrounded by the rod electrodes (21 through 28). Ions are accelerated in accordance with this gradient. Therefore, even in the case where the gas pressure is relatively high and ions have many chances to collide with gas, it is possible to moderate the ions' slowdown and prevent the ions' delay and stop.
