Patent number: 7527221Abstract: A mounting device for aircraft comprises an energy absorber and wherein the mounting device is mounted between a primary structure of the aircraft and the interior equipment. In this way the load acting on an interior equipment connected to the primary structure of the aircraft by way of the mounting device can be limited if a crash impulse occurs. The load acting on the primary structure is also limited, which can result in enhanced passive safety for the passengers and in weight reduction.Type: GrantFiled: August 30, 2005Date of Patent: May 5, 2009Assignee: Airbus Deutschland GmbHInventors: Dirk Humfeldt, Michael Harriehausen, Jan Schroeder, Martin Sperber, Michael Demary

Patent number: 7183871Abstract: An improved bi-directional access point includes an impedance boosting section in conjunction with an interface section to a bi-directional communication path. The impedance boosting section incorporates a transformer tap output that couples to an access connection point where signals on the bi-directional communication path may be monitored. The impedance boosting section may be a tapped transformer winding that includes N1 turns above the winding tap and N2 turns below the winding tap, where N1>N2. The interface section may be implemented as a resistive interface section. Additionally, the bi-directional access point may further include a tuning section for the access connection point. Implemented as a resistive network, for example, the tuning section may help establish a tap value and return loss through the access connection point below a prescribed level (e.g.,?20 dB).Type: GrantFiled: May 7, 2001Date of Patent: February 27, 2007Assignee: Viewsonics, IncInventors: Martin Sperber, Shaun Shariatmadar

Patent number: 6646519Abstract: An RF equalizer is implemented using a voltage divider L-attenuator. The RF equalizer provides a frequency variable compensation attenuation and generally includes a series impedance and an impedance to ground (i.e., a shunt impedance). The primary components of the series and shunt impedances are resistances. Preferably, the series impedance also includes a parallel combination of a bypass circuit (e.g., a series inductance and capacitance) and an augmenting circuit (e.g., a capacitor), while the shunt impedance is formed from a series RLC circuit. The bypass circuit, when implemented as a series LC resonant circuit, is preferably tuned to present a minimal impedance (i.e., a short or bypass) around the series resistance at the highest frequency of interest (e.g., 1000 MHz). At frequencies below resonance, the bypass circuit provides a net capacitive reactance which is augmented by the fixed capacitor in the augmenting circuit.Type: GrantFiled: May 7, 2001Date of Patent: November 11, 2003Assignee: Viewsonics, Inc.Inventor: Martin Sperber

Patent number: 5661801Abstract: A method and apparatus are provided for preventing the existence of pseudo-sync pulses and added AGC pulses in an original video tape with copy protection from producing a poor t.v. picture when simply played on a VCR and viewed on a t.v. monitor. In a first embodiment, the horizontal sync pulses are amplified to eliminate jitter in the signal due to confusion with the chrominance or color burst signal. Further, the color burst signal may be subject to variable gain to correct the color tint. Finally, if desired all portions of an input video signal may be amplified, except for portions of the signal where pseudo-sync pulses and added AGC pulses are normally found, in order to brighten the signal. In another embodiment, all portions of the signal are amplified and the portions of the signal corresponding to pseudo-sync pulses and AGC pulses are attenuated to their normal 1 volt peak-to-peak level.Type: GrantFiled: February 14, 1995Date of Patent: August 26, 1997Assignee: HSN Marketing Inc.Inventor: Martin Sperber

Patent number: 4446407Abstract: A control circuit for an antenna rotator includes a difference amplifier which develops a motor drive signal of both positive and negative polarity for rotation of a DC motor in both clockwise and counterclockwise directions. A feedback loop circuit for control of the motor is provided by a sensor of antenna position, the sensor being coupled between the antenna and the amplifier. Friction in a gear train coupling the motor to the antenna isolates the circuit from wind induced vibrations of the antenna.Type: GrantFiled: March 8, 1982Date of Patent: May 1, 1984Assignee: Intercept CorporationInventor: Martin Sperber
