Abstract: An analog-to-digital conversion circuit having a number of series-connected stages, each stage determining the difference between a signal current input and a reference current input, and at positive values of said difference transferring a current proportional to said difference to the succeeding stage. In each successive stage, the reference current is subtracted from the signal current until the residual current is smaller than the reference current. The number of successive stages in which this subtraction takes place can be detected to indicate the level of the input current. Each stage includes a common point for receiving the difference between the signal current and the reference current, a current path from said common point to its output for transferring a current proportional to the difference if positive, a current path from said common point to a current sink if said difference is negative; said current paths being unidirectional and biased such that only one is forward biased at one point in time. Each stage also detects the polarity of said difference to obtain a digital measure of the value of the signal current.

Abstract: Disclosed is a disposable contraceptive in which a first member engages the vaginal vault and a second member, secured to the first member, engages and closes the cervical opening. The first and second members are substantially discoid, with the second member smaller in discoid area than the first. The second member is a generally impermeable sponge-like material which is lubricated to aid in adhesion and closure of the cervix. The first member is generally resiliently closable so that the overall dimension of the contraceptive may be reduced in size for insertion into the vaginal vault. The first member is defined at least by opposed anterior and posterior portions which engage the respective anterior and posterior portions of the vaginal vault. The second member is coupled or joined to the first member at the posterior portion. In one embodiment, the second member is a sponge joined to a film. The film is held in position to define the first discoid member surface by a rim. In other embodiments, the first and second members are resiliently joined at the posterior portion so as to urge the second member into positive engagement with the cervix. Thus, a finite resilient nylon filament is bent into a figure 8 and covered with a soft, yieldable, foam plastic covering. By folding at the intersection of the upper and lower loops, the contraceptive is formed. In another example, a liner of resilient plastic in the shape of conjoined circles is covered by a soft, flexible, plastic envelope. In yet another example, an annular discontinuous rim is covered by a foam plastic. The rim has an integrally formed tongue extending therein and about, to which may be secured (by any well known means) a sponge-like impermeable plastic second member.
