Abstract: A delivery device for controllably delivering multiple implants (e.g., intravascular implants) is described herein. The delivery device may include a lockout mechanism to prevent against inadvertent implant deployment prior to initial use. The delivery device may also include a re-sheath mechanism to allow for re-sheathing of an inner core assembly prior to removal of the delivery device from an initial deployment site. The delivery device may also further include a mechanism configured to prevent against re-sheathing of a partially-deployed implant.

Abstract: An addressable subscription television decoder includes an input stage including an IF amplifier for converting a scrambled RF television signal to a composite baseband video signal. The baseband video signal comprises either a nominal sync component or a sync component having suppressed horizontal sync pulses during video fields and having non-suppressed sync pulses during vertical intervals, the vertical intervals also including selected encoded data signals. An AGC voltage for controlling the gain of the IF amplifier is developed by a circuit exhibiting a relatively short time constant whenever the composite baseband video signal is characterized by nominal level sync pulses, the time constant being increased in response to suppressed horizontal sync pulses. The sync pulses produced during the vertical intervals of the composite baseband video signal are thereby not subjected to excessive IF gain for facilitating processing of the data signals by the decoder.

Abstract: A decoder includes an oscillator supplying a decoding signal to the control input of an RF modulator for decoding a sine wave encoded television signal. The decoding signal developed by the oscillator is randomly phase locked in either of two states with the output of a horizontal sync separator operated in response to the detected output of the RF modulator. In the first phase locked state, the decoding signal is in antiphase relationship with the encoding modulation resulting in a properly decoded baseband video signal. In the second phase locked state, the decoding signal is in phase alignment with the encoding modulation so as to constructively combine therewith. The second phase locked state is detected and broken each time it is assumed allowing the decoder to eventually assume the first phase locked state wherein a properly decoded video signal is produced.

Abstract: A pulse interference detector is disclosed for use in a capacitance electronic disc player (CED). A relatively short-duration, high-amplitude periodic interference pulse, such as a radar pulse, is detected. The video carrier signal of the CED has a first envelope aberration in the form of a relatively long peak-to-peak duration amplitude modulation component, and a second envelope aberration in the form of the interference pulse. The CED incudes a defect corrector for inserting, when triggered, preceding unblemished display line information into a current display line void. The pulse interference detector receives and processes the video carrier signal and also detects the interfering radar pulse. The detector comprises a first signal path responsive only to the amplitude modulation component, and includes a resistor-capacitor network for producing a reference component substantially representing an average of the envelope excursion of the component.

Abstract: A solid state network for subscriber station is amenable to hybridization and mass production, minimizing costly, heavy components, facilitating transmission and reception of communication signals almost independently of variation in line impedance, and controlling a sidetone level with in-phase signals, through the use of as few as one transmitting transistor that is in series with the transmitter and also in series with the receiver, and as few as one receiving transistor.

Abstract: A solid state subscriber station network which provides transmitting, receiving and regulating functions using a single active element. The transmitted signals, the received signals and the regulatory functions can be separately varied within proscribed limits without adversely affecting the other functions.

Abstract: A solid state network for subscriber stations which uses a first active element to couple both the transmitter and the receiver to the telephone lines and uses non-inductive component for compensation to minimize costly heavy components and to facilitate transmission and reception of communication signals almost independently of variations in line length.
