Abstract: An apparatus and method for treating erectile dysfunction by using a pulsating, ultraweak, magnetic field. A transducer generates an ultraweak, pulsating magnetic fields which is applied to the penis, which as a result of the magnetic field causes the erection of the penis. Another aspect of the invention is an apparatus and method for treating medical conditions in women by using a pulsating, ultraweak, magnetic field.

Abstract: A method and an apparatus for the treatment of cardiac hypertrophic heart failure, hypertropic cardiomyopathy, atrial or ventricular brady-arrhythmias (slow heart rate), atrial flutter-fibrillation and similar cardiac ailments, as well as peripheral vascular disease and hypertension, using a weak pulsed magnetic field or a very weak magnetic field. A transducer that emits weak electromagnetic radiation is placed on the patient's chest or legs and, as a result the very weak electromagnetic field can cause activation, reactivation, inhibition or remodeling of electrophysiological change in cardiac tissue in an irradiated heart or vessels. This treatment method has wide application for use in patients with various heart and vascular ailments.

Abstract: A system and a method for automated setting of radiation treatment devices using a master computer. The method allows the physician to digitally control the patient's treatment from a master computer and make rapid and fine adjustments in multiple treatment devices. The multiple treatment devices may be situated at the doctor's office, in which case they are connected to the master computer via a local area network (LAN). Alternatively, a network may be used (e.g., the public telephone switching network, an intranet or the Internet) to enable the physician to send radiation therapy from a central location (e.g., a doctor's office) to PC computers or treatment devices at remote sites (e.g., patients' residences). In the former case, the treatment parameters and protocol are then loaded into the radiation treatment device from the remote PC computer, allowing the patient to receive radiation at home or any other preferred location at his/her convenience.

Abstract: A programmable telephone call restriction device and a related method for remotely programming the call restriction device from an interactive voice response system or other computer. The call restriction device is connected in parallel at any point along a telephone connecting the telephone to be restricted and the local telephone exchange. If the user of the telephone dials a number that appears in a list of restricted numbers, the call restriction device will generate DTMF signals that prevent the telephone line from being used even if a connection is made to the dialed number. To program the call restriction device, the telephone user must first establish a telephone connection to the IVR system by dialing an access number. In response to a voice prompt from the IVR system, the telephone user must then input a valid authorization code, i.e., a valid personal identification number (PIN).

Abstract: A substantially zero average DC output voltage is obtained in an instrumentation amplifier without degrading the gain by detecting the output of the amplifier and operating a non-galvanically coupled device responsive to the detected output to apply feedback to the amplifier for balancing out common mode output voltages.

Abstract: A pulse detector system for reliably counting pulse signals generated by calling party telephone dials. The system includes generating a dial pulse template based on a sample train of pulses. A preferred embodiment uses a pulse amplitude template comprising an amplitude histogram.

Abstract: A telephone system enabling prepayment for telephone calls, wherein special code and credit information is stored in memory in special exchanges and debited as the call progresses.

Abstract: Improved cryogenic magnet systems for use in NMR imaging devices comprising an electro-magnet immersed in a first tank containing a first liquid gas, the first tank located in a container evacuated to a high vacuum, a refrigerating system external to said container, and coupling means for coupling a cold head of the refrigerating system to radiation shielding means surrounding said first tank for lowering the temperature of the shielding means to thereby reduce boil-off of said liquid gas.
