Patent EP-0637191-A2 (EP)
Inventor: TOSHIYUKI IIDA
IPC: H04S1/00
Filed: 1994-07-29
Abstract: A surround signal processing apparatus is disclosed, by which an inputted rear surround signal can be reproduced, together with two-channel front stereophonic signals, through a pair of speakers arranged in front of and in substantially right-and-left symmetry about a listener, in such a way that two sound images of the reproduced rear surround signal can be localized at two predetermined positions relative to the listener. The inputted rear surround signal is processed by a filter. The signal processed by the filer is added to one of the stereophonic signals, and then outputted to one of the pair of the speakers. Further, an inversion signal of the filter-processed signal is added to the other of the stereophonic signals, and then outputted to the other of the speakers. Here, the transfer characteristics of the filter is determined as follows: (F - K) / (S - A), where S denotes transfer characteristics between one of the speakers and one of the listener's ears positioned on same side as the speaker, respectively; A denotes transfer characteristics between one of the speakers and one of the listener's ears positioned on opposite side to the speaker, respectively; F denotes transfer characteristics between one of the two positions at which two sound images are required to be localized and one of the listener's ears positioned on same side as the image position, respectively; K denotes transfer characteristics between one of the two positions at which the two sound images are required to be localized and one of the listener's ears positioned on opposite side to the image position; and / denotes reverse convolution calculation.

Abstract: The activation system is used for an end stage with a pair of power transistors (T1, T2) controlling an electrically operated release device (Z), e.g. an air-bag detonator, respectively coupled to an operating potential and a reference potential via the transistors. Each transistor has an associated current detector (S1, S2) and is supplied with a respective control signal (Ust1, Ust2). The control signals have different durations with a partial overlap between them and are used for successive closure of the transistors, so that the current flow is indicated by the respective current detectors, the signal indicating the current flow through one transistor used to maintain the current flow through the second transistor, during the non-overlap duration of the control signals. <IMAGE>

Abstract: Switching noise at integrated circuit V DD  and V SS  metal traces is reduced by minimizing lead inductance in on-chip bypass capacitors. For each on-chip bypass capacitor, a pair of V DD -carrying and V SS -carrying metal traces is formed, these traces having regions spaced-apart laterally a distance ΔX corresponding to lateral separation of the bypass capacitor connecting pads. For each bypass capacitor, column-shaped openings, spaced-apart distance ΔX, are formed through the passivation and inter-metal oxide layers, as needed. These openings expose and access regions of the pair of spaced-apart metal traces carrying V SS  and V DD . These openings, which may be formed after the IC has been fabricated, preferably are formed using focussed ion beam technology ("FIB"). Alternatively, these openings may be formed using masking and etching steps. The column-shaped openings are then made into conductive columnar elements, preferably using FIB deposition of tungsten or platinum. Conductive element pads are formed atop the conductive columnar elements at the outer surface of the IC passivation layer. The bypass capacitors are then attached to the IC, and the capacitor connecting pads are electrically connected to the respective conductive element pads using conductive epoxy or other conductive bond material. This direct attachment of the on-chip bypass capacitors reduces effective capacitance lead inductance and improves attenuation of on-chip switching noise.

Abstract: An improved configuration of a capacitor formed with FET technology and a resistor and/or inductor is provided. In this configuration a capacitor is formed in which the diffusion zone of the substrate is used as one plate of the capacitor and what would normally be the gate electrode of an FET is used as the other plate of the capacitor, with the two plates being separated by a conventional thin dielectric gate oxide layer. An insulator, such as silicon dioxide overlays the gate electrode, and electrical connections to the gate electrode and diffusion zone are made through the insulator to allow the two plates of the capacitor to be connected to various devices or components as required. The top surface of this insulation layer is also used to form metal resistors. Depending on the value of required resistance, a second insulating layer may be used and a second level of metal used to connect segments of the resistors formed on the first layer of metal to form a longer resistor. This second layer of metal may also be used to form inductors. Moreover both inductors and resistors can be formed; however this may require a third layer of metal for connection purposes.
