Abstract: A patient monitoring system within an Electroconvulsive Therapy (ECT) device includes a patient monitoring channel including a first electrode and a second electrode, with each electrode coupled to a respective lead. The monitoring system also includes an Alternating Current source structured to inject a test current to the first electrode lead or the second electrode lead and a differential amplifier structured to measure differences between signals received from the first electrode lead and the second electrode lead. Related methods include evaluating a quality of an electrode contact with a skin surface by injecting a lead of the electrode and one input of a differential amplifier with a known electrical current, comparing a difference between an electrical signal received from the lead of the injected electrode as well as from a lead of a passive signal electrode, and evaluating the compared difference.

The ECT device further includes a power monitor configured to measure average electrical power that is being delivered to the patient through the series of electrical therapeutic pulses in real-time during a treatment session, and to cause the therapy generator to cease operation after a predetermined threshold level of average electrical power has been delivered to the patient. Related methods are also disclosed.

Abstract: A method of propelling a transit vehicle steered by a centerline electrified structural guidebeam located between two special steel load-bearing rollway beams, using magnetic linear motors suspended between each pair of steerable load-bearing wheels, to react inductively on the rollway beams, to produce tractive effort by four linear motors mounted under an eight wheel car.

Abstract: An analog signal is digitized by an analog-to-digital (A/D) converter clocked by a periodically jittery clock signal. Elements of the digital data sequence (vector) output of the A/D converter are sorted into a set of smaller vectors according to clock signal jitter phase and each of the smaller vectors is then separately subjected to Fourier transform and time shift functions. The resulting vectors are then processed to produce an output vector representing the frequency spectrum of the analog signal.

Abstract: A high-pressure computer controlled chamber, processing high-temperature combustion gases combining with a vaporizing liquid, to create a high-energy flow to an expansion engine to do variable-rate work.

Abstract: A mechanism is disclosed for actuating the intake and exhaust valves of a reciprocating multiple cylinder external combustion vapor expansion engine in either forward and reverse rotation. Electrical solenoid and pressure actuating valve mechanisms responding to a sophisticated digital computer program replaces the cam shafts, push rods, adjustable tappets, throttle, fuel injection, and cooling systems of a conventional internal combustion Diesel engine. The computer integrates the many system variables, including, temperature, pressure, speed, friction, mass, and acceleration to obtain the optimum efficiency of shaft work output.

Abstract: A mechanism is disclosed for actuating a switch guide beam swinging laterally between two or more fixed guide beam ends, in order to make a route selection for a beam guided vehicle. The moving guide beam pivots distantly of the primary fixed guide beam end to create a gap spanned by an intermediate suspended channel plate guide segment that provides substantially two equal lateral deflections to the moving vehicle for a route diversion in a storage yard or repair shop area. The mechanism for high speed or main line operation has two additional channel plate guide segments slidably guided at each end of the guide segment centrally affixed on the straddle beam and pivoted at the primary beam fixed end and the merge point on the radially moving swing guide beam to provide four substantially equal lateral deflections to the moving vehicle when a route diversion is required.

Abstract: A mechanism for steering a beam guided vehicle having four steerable wheels linked to a centrally located steering trolley guided by an electrified T-shape beam mounted on a structural roadbed. A trolley flexibly propelled by the vehicle follows the guide beam to actuate the steering of the wheels. The trolley is quickly detachable by drop-pit access for rapid change-out to periodic off vehicle servicing. Two steering arm sensor posts engaging two sockets in the repositioned trolley guarantee interchangeability of standardized repaired units.

Abstract: An electro-convulsive therapy (ECT) system includes both hardware and software safety detectors and monitors generator that generates a pulse train of a plurality of pulses with parameters specified by the user. The safety monitors monitor these user-specified parameters as well as other important pulse parameters both during treatment of a patient and prior to treatment in order to ensure that the system is operating according to specification and, therefore, will not injure the patient. The pulse generator is responsive to the safety monitors in that if any of the safety detectors detect a parameter that is out of tolerance, the safety monitor disables the pulse generator so that no further pulses are delivered to the patient. The safety detectors detect the plurality of pulse characteristics including pulse width, frequency, voltage, current, treatment duration, as well as energy.

Abstract: Disclosed is a device 10 for a video screen 16 which includes a support member 12 member disposed about the circumference of the video screen 16. The support member 12 has walls with interior reflective surfaces 30. A plurality of point light sources or lamps 32 are mounted to the support member 12 and positioned to provide to inner and outer concentric frames 50 and 52 of light on the screen 16. The inner frame 52 comprises a series of discrete point light images or dots 46 near the circumference of the screen 16 formed by light from the light sources being cast directly onto the screen. The outer frame 50 comprises a series of discrete point light images or dots near the circumference of the screen 16 formed by light from the light sources 32 first reflecting off the reflective surfaces 30 and then onto the screen 16. The intensity of the light from the inner frame 52 is less than the intensity of light from the outer frame 50.

Abstract: Apparatus for streaking a beam of light employing a crystal in which an electromagnetic wave pulse induces a synthesized traveling lens. Surfaces on opposite sides of the crystal act as light reflectors to create multiple cross-reflections of the beam relative to the crystal, thus to enhance the lensing effect of the crystal. Production of the electromagnetic wave pulse is coordinated with impingement of a beam of light, and the geometry of parts is arranged whereby each coherent wave front in the beam, as it passes multiple times through the crystal, on each such passing encounters the same substantially constant lens condition which has been induced in the crystal.

The engine may also be adapted for use as a compressor.
