Title: Programmable logic device with redundancy
Inventor: PATEL RAKESH H
IPC: G06F11/20
Filed: 1995-01-31
Abstract: When a portion of a programmable logic device is found to be defective, redundant circuitry is switched into use in place of the defective circuitry. The programmable logic device is arranged in rows and columns of programmable logic containing logic array blocks 12, which a user selectively configures by loading programming data into vertical and horizontal programming blocks. When the redundant circuitry is switched into place, the programming data is redirected to the appropriate programing blocks. The outputs of each block 12 go to demultiplexers 24, multiplexers 28 and tristate drivers 26 connected to row and column conductors. When a defective row of blocks 12 is switched out of use, a spare row being switched in, input/output pins 18 for the row conductors are reconnected to respective adjacent rows instead, as necessary (by circuitry not shown in Fig. 2). <IMAGE>

Abstract: Arrangements are provided which allow elimination of various diodes or semiconductor switches provided in prior art circuits (Figs. 1-8) in a battery charging or discharging path, whereby the power loss due to such components is avoided. A note-type personal computer may be powered by an internal battery or by an external source which also charges the battery, charge controller opening a switch (150, Figs. 9A, 11,12) between the battery negative terminal and the ground side of the computer circuits during charging. A battery pack may have an overdischarge prevention circuit 220 which turns off an FET21 in series with the battery in response to sensing overdischarge and in response to excess discharge current, another FET22 being turned off in response to excess charging voltage. The circuit 220 also has an external input 260 to which is applied a signal from a control section 281 of the apparatus powered by the battery, so that the FET's21, 22 can also be used as a battery on/off switch. Control section 281 operates a priority scheme so that the apparatus is supplied from the external supply if connected, or from a first battery 210 and then from a second battery 210' when battery 210 has discharged to a certain level. Two battery packs may be charged in parallel from a single constant current/constant voltage charging circuit (300, Figs. 10A, 15) which responds to whichever is the higher of the two battery charging currents and also responds to whichever is the higher of the two battery voltages when either voltage is above a reference level. Alternatively, two batteries may be charged in a time division manner from a constant current source (Figs. 10B,17). The batteries may discharge in parallel via respective DMOS-FET's (43, 44) which have parasitic diodes poled in the battery discharge direction. The gates of these FET's are connected to the external supply input so that they turn off when the external supply voltage is present. <IMAGE>

Title: MALDI time-of-flight mass spectrometers
Inventor: FRANZEN JOCHEN
IPC: H01J49/16
Filed: 1997-09-02
Abstract: In the exact mass determination of analyte ions in time-of-flight mass spectrometers, using matrix-assisted laser desorption (MALDI), and with delayed ion acceleration in the field between the sample support 1 and an intermediate electrode 2, a method is provided for correction of flight time values if an incorrect adjustment of the distance from the sample support to the nearest acceleration electrode has occurred. A reference substance is used to calculate a correction parameter which is used to correct all flight times using a quadratic correction equation, before using a pre-calibrated mass scale for the calculation of the exact masses. The quadratic correction equation contains a control parameter which multiplicatively affects both the linear and quadratic correction term. If no better suitable reference ions are available, oligomeric ions from the matrix of the MALDI ion source may be used as reference ions.
