Title: Pulse generators
Inventor: SCHIFFMANN ROLF
IPC: H03K3/017
Filed: 1991-06-21
Abstract: A circuit arrangement for the broad-band frequency doubling of a pulse signal with a constant pulse duty factor of 50% includes a monostable multi-vibrator or flip-flop (2) whose nominal time constant is established by a resistor/capacitor combination (5, 6) and which is triggered by both positive and negative-going edges of an input pulse signal Uin. Complementary output signals (U1, U2) of the flip-flop (2) are low-pass-filtered (14, 18) and supplied to a differential integrator (15, 16, 17) for deriving a control voltage (U5). The latter adjusts the time constant of the flip-flop (2) in the direction to establish the desired constant pulse duty factor of 50% of the frequency-doubled pulses at the output. The duty factor remains constant even if the input pulse frequency changes by 30%. A modified circuit is used for TTL signals. <IMAGE>

Title: Miniature silicon accelerometer and method
Inventor: O'BRIEN BENEDICT BUTLER
IPC: G01C19/5719
Filed: 1991-12-23
Abstract: A miniature accelerometer is fabricated using integrated circuit manufacturing and silicon micromachining techniques to form a closed loop, force balance sensor 12 utilizing a silicon proofmass 16 formed from and connected to a layer of silicon 24 by a split flexure 22 etched therein. The sensor circuitry 14 detects AC signals coupled from the proofmass to a pair of electrodes 30, 32 formed on glass layers 26, 28 anodically bonded to the silicon layer. A DC restorative force is applied to the electrodes 30, 32 in response to the detected AC signals to balance acceleration forces applied to the proofmass. The sensor design is highly symmetrical. The proof mass receives applied voltages from DC bias source 35 and AC source 38, the resultant signals on electrodes 30, 32 being fed to amplifier 60 via a diode quad bridge. The amplifier output signal, at point 34, is of magnitude and sign corresponding to the sensed acceleration and is fed back to the electrodes 30, 32 (via an inverter 62 in the after case). Conductive guard bands 64, 66 are provided on the glass layers 26, 28 around the electrodes. To prevent the proof mass touching one of the electrodes if the device is under acceleration at start-up, the guard electrodes have inward fingers 74-77 corresponding to cut-outs in the electrodes, and contact posts are provided on the proof mass as at 78, 79, Fig. 3. <IMAGE>
