Title: Curved flange sidewall construction for railcar end structure
Inventor: FORBES JAMES WILFRED
IPC: B61D3/20
Filed: 1996-04-30
Abstract: An end structure for a railroad freight car having longitudinally extending and spaced apart side structures. Each of the side structures provide top and bottom longitudinally disposed structural members which are spaced apart and connected to the end structure. Each of the top and bottom members have a terminal end portion. The bottom member is shorter in length than the top member to define an overhanging relationship between the top and bottom members in an area of the end structure outboard of the terminal end portion of the bottom member. The end structure comprises a planar sidewall extending between the top and bottom members. The sidewall has top and bottom edges. The top edge is joined to the top structural member. The bottom edge consists of an inboard straightedge portion, an intermediate curved portion and an outboard straightedge portion. The inboard portion is joined along its length to the bottom structural member. The curved portion extends upwardly from the inboard portion adjacent the terminal end portion of the bottom structural member and merges with the outboard portion of the bottom edge of the sidewall. The curved portion defines a curved edge having a positive slope of constantly decreasing value when measured from the inboard portion to the outboard portion. The end structure further comprises a one-piece curved flange connected to the terminal end of the bottom structural member and to the curved portion of the bottom edge of the sidewall along the entire length thereof. The sidewall consists of a single web in the area of the end structure outboard of the terminal end portion of the bottom structural member and inboard of the terminal end portion of the top structural member. The continuous curvature of the flange is designed to reduce stress risers associated with geometric discontinuity, to enhance fatigue resistance of the flange itself and the end structure, and to facilitate access by an operator to a truck supporting the end structure.

Title: Method of verifying capture of the heart by a pacemaker
Inventor: SCHROEPPEL EDWARD A
IPC: A61N1/37
Filed: 1994-12-08
Abstract: A method of verifying cardiac capture. A cardiac signal evoked in response to a cardiac stimulation pulse is sensed via an electrode. The sensed signal is lowpass filtered to remove noise and to pass frequencies characteristic of the evoked cardiac signal. The filtered signal is processed to tender a waveform signal representing the second derivative of said filtered signal and the second derivative signal is further analyzed to detect a minimum and a maximum amplitude excursion during a selected window of time beginning at a selected time delay following delivery of the cardiac stimulation pulse. The amplitude difference between the minimum and the maximum is measured and compared to a first reference value. The amplitude of the second derivative is measured during a second selected window of time beginning at a selected time delay following delivery of cardiac stimulation pulse, and compared to a second reference value. A capture detect signal is generated if the amplitute difference exceeds the first reference value, but the amplitude does not exceed the second reference value.

Title: Dynamic traffic light
Inventor: KASHEFY HAMID
IPC: B60Q1/44
Filed: 1996-07-24
Abstract: In the present invention, which takes the place of centre high mounted stop lamps on vehicles, orange, green and red lights are used to implement a simple language of light, in order to dynamically inform following drivers about speed variations of leading vehicles at any time (Figure 1). Also in this invention, different configurations of orange, red and green lightssymbolise different levels of speed (Figure 4 to Figure 14). A unit of speed is defined. As frequency counters and digital speedometers, dynamic traffic light counts (from zero) the number of pulses that occur during a predetermined  time interval  (Figure 15). Unlike  frequency counters and speedometers, which display frequency in hertz or as speed respectively, dynamictraffic light indicates one unit decrease or increase in speed (or in the frequency of pulses that are generated by speed sensor) by flashing light(s) of said colours. The speed at which flashing of a light of any colour happens is registered as reference speed. When the difference between the current speed (ie: current value of counter) and the reference speed (ie: the value stored in register) is equal or greater than one unit of speed, a flashing of a light of a particular colour arises and register is updated to the current value of counter. Furthermore, I have discovered that a 555 timer and a LM339 quad voltage comparator can together function as a transmitter and receiver which also alleviate the implementation of this invention. That is, instead of extending a wire from the speed sensor to the dynamic traffic light in the rear of vehicle, a 555 timer transmits the amplified speed sensor pulses one by one to the receiver in the rear of vehicle, through the fog light wire from which both the transmitter and its associated receiver obtain their power. The transmitter does not after the voltage or current through the line of electricity from whichboth the transmitter and its associated receiver obtain their power. Every approximately 130m, the same method can be used in order to regenerate andtransmit pulses to a further distance.
