Abstract: The present invention pertains to a structure resistant to the transmission of forces of impact which is useful in the fabrication of articles subjected to impact forces by the user of the articles. The structure includes a double plush-like open mesh structure having first and second layers of interlaced stretch-resistant flexible strand material positioned adjacent each other, and defining an intermediate space therebetween. A plurality of elongated partitions are disposed between the first and second layers and divide the intermediate space into a plurality of elongated generally parallel channels. The partitions each comprise a plurality of pile stretch-resistant strand material connecting with the first and second layers in a plane generally perpendicular to the first and second layers. Resiliently-compressible single cell fluid-impermeable tubular members are disposed within at least a majority of chambers and adaptable to be inflated under fluid pressure to within the confining limits of the chamber walls to provide a cushioning and impact absorption structure.

Abstract: A power generation system is constituted by an induction generator (2) and a converter (3). An output current waveform of the induction generator (2) is determined by the magnetic flux, speed, winding impe­dance, DC output voltage, and load of the induction generator (2). In particular, the output current wave­form is changed in accordance with a change in speed (i.e., change in slip). Switching elements (21 - 26) in the converter (3) are ON/OFF-controlled in accordance with changes in current waveform, thereby controlling power generation of the induction generator (2).

Abstract: A standard keyboard or keypad for a coin operated telephone is connected to balance an artificial line rather than the actual phone line. The artificial line simulates operating conditions at the end of the loop regardless of whether the phone that the keyboard is in is actually near or far from the central office. As a result, the standard keyboard can be operated using a current at or near its designed minimum operating current. Additionally, a microcontroller for controlling the operation and decoding of the keyboard is programmed to have a small duty cycle of on time during decoding so that the bulk of the power normally used by the microcontroller can be switched to the keyboard when it is detected that a key is depressed. Thus, a line powered low power controller can be used in conjunction with a standard keyboard. By reducing the number of lines used to connect the standard keyboard to the controller, an extra line is made available which allows the controller to be utilized with either a standard or a modified keyboard.

A plurality of said dummy cells (22) has a bit value stored therein and is connected to a dummy word line and the remainder of said dummy cells are rendered inactive, whereby on addressing of the dummy wordline simultaneously with the wordline of an accessed cell, a predetermined number of dummy cells discharges via the dummy bit line so that the voltage developed on the dummy bit line is a fixed multiple of the voltage differential developed between the bit lines of the accessed cell. The timing circuit (16) is connected to receive the voltage differential on the dummy bit line (18).
