Title: Cardiac pacemaker and voltage reference and regulator therefor
Inventor: STOTTS LAWRENCE J
IPC: A61N1/365
Filed: 1989-02-09
Abstract: A cardiac pacemaker (10) has a sense amplifier 
(20) responsive to signals representative of cardiac 
activity for passing signal components lying in a 
selectively variable pass band and for selectively 
varying the gain of the passed signal. A pair of 
signal comparators (58, 59) constituting switched 
capacitor amplifiers, associated with the sense 
amplifier (20), are responsive to the filtered and gain 
adjusted signal for comparison of its magnitude to 
predetermined target levels for determination of heart 
rate and the need for change of rate. Two target 
levels are provided in each comparator (58, 59) for 
comparison with the level of the detected signal, by 
multiplexing the switched capacitors. Another 
switched capacitor amplifier (99) is used to develop a 
voltage reference level insensitive to temperature, 
supply voltage, and circuit components, for deriving 
the target levels for the comparison. Still another 
multiplexed switched capacitor amplifier comparator 
(125) is used to develop a first target level to 
regulate the level of the pacing stimulus, and a second 
target level for comparison with the supply voltage 
level of the pacemaker as a measure of the point at 
which the pacemaker requires replacement.

Title: Pile unleader for removing a sub-pile from a pile of sheets
IPC: B65H31/30
Filed: 1990-09-12
Abstract: Two vertically displaceable slides (5, 9) carry in horizontally movable fashion a tabletop (1) and, respectively, a gripper with an upper gripper jaw (6) and a gripper base (7). The gripper base (7) contains a horizontally displaceable blade (12) and supporting elements (24, 25) which are horizontally displaceable and also vertically movable with respect to the blade (12). A Stack of sheets is set up in front of the tabletop (1). The slides (5, 9) are lowered until the upper gripper jaw (6) rests on the sheet stack. The blade (12), previously retracted into the gripper base (7), is then made to pierce the stack of sheets at an exactly settable distance below the upper gripper jaw (6). The slides (5, 9) are slightly elevated in order to form a gap in the sheet stack with the blade (12). The supporting elements (24, 25) are pushed into the gap below the blade (12), and are then urged upwardly past the level of the blade (12) so that they alone bear the weight of the sheets resting thereon. Upon further elevation of the slides (5, 9) until the tabletop (1) can be introduced into the gap, the blade (12) thus cannot damage the sheets.

Patent EP-0559957-A3 (EP)
IPC: H04M1/72502
Filed: 1992-10-23
Abstract: Radio transceiver according to the DECT specification (Digital European Cordless Telephone) which can be implemented at particularly low cost, while nevertheless being extremely powerful and adaptable to different transmission formats. The radio transceiver according to the invention allows any given sequence of the data from different data sources to be produced in a bit rate converter through switchover of the address source and data source of the bit rate converter. The transmission protocol can thereby be modified and the reading of the data into and out of the bit rate converter can be carried out at a higher bit rate than the rate at which the data are made available from the individual sources. Because the individual modules can be implemented by means of a small number of simple components, the radio transceiver according to the invention is also particularly inexpensive. Since the transmission format can be easily modified, the transceiver according to the invention is suitable for all types of data transmission in a time-division multiplex transmission system. <IMAGE>
