Abstract: The device for the comparison of the levels of two input signals MI, PI includes a first comparator COMP1, the switching of the comparator being expressed by a change-over of the output OUT1 of the comparator from a first logic state into a second logic state, the change-over of the output OUT1 from one logic state “0” into the other state “1” being faster than the change-over in the other direction. The device also includes a second comparator COMP2 with an identical structure, to whose input the signals to be compared are applied invertedly so that the switching operations in the comparators are inverted. The output of each comparator is applied to an associated logic circuit 1, 2 capable of accelerating the inverse switching in the other comparator for a change in the output corresponding to the fastest change-over.

Abstract: A disposable penile constriction device and associated methods are provided. The disposable penile constriction device preferably includes a strip of bendable and stretchable material formed in a closed band shape when in a closed position so that inner surface peripheries of the strip of material substantially surround and abuttingly contact outer surface peripheries of a proximal portion of a penis when positioned thereon and a preformed predetermined tear region formed in the strip of material which readily allows tearing of the strip of material by the hand of a user so that the closed band shape is separated to an open position and the strip of material can be readily removed from a proximal portion of a penis without the necessity of moving the strip of material over a distal end of a penis.

Abstract: A customer operated counter-top terminal system activates various debit card transactions, provides secure communications with a host computer database, and issues a decrypted authorization code to the customer. The system consists of a main terminal unit with an alphanumeric display. The main terminal unit carries a CPU, memory, and all interface devices, including a keypad for the entry of Personal Identification Numbers (PIN), plus programmable function keys and a swipe reader for reading various cards. The main terminal unit further includes a printer for printing receipts for use by a customer and retailer. The system also includes a remote hand-held keyboard having a keyboard display, typically to be held by a clerk for providing a level of privacy desirable to the customer.
