摘要： A physiological sensor device is attachable to the skin of a person for collecting physiological signals generated by the person's body. The device includes a flexible front layer made of a material that does not conduct electricity and a flexible back layer made of a material that does not conduct electricity. A flexible intermediate layer made of a material that does not conduct electricity is sandwiched between and fixed to the front layer and the back layer. Electrodes and electrical conductors are fixed to a back side of the intermediate layer. Each of the electrodes is attached to one of the electrical conductors and all of the electrical conductors are attached to a single common connector that protrudes through a portal in the front layer. A conductive gel pad is adhered to and aligned with each of the electrodes and protrudes through a portals in the back layer to contact the skin of a person when the physiological sensor device is attached to the skin of a person. Each layer of the physiological sensor device has, when attached to a standing person's chest, a vertically extending portion with a horizontally extending portion located at a lower end of the vertically extending portion to give the physiological sensor device a shape like an inverted T. The vertically extending portion is intended to overly a person's sternum and is sized to comfortably fit either a male or female patient.

摘要： In railway signaling systems which transmit rate code signals along track circuits, which signals are picked up by the trains and used for signaling purposes, such as speed control, the rate code signals of the same repetition rate received when the train passes between adjacent track section may suffer a phase shift, also known as a phase jump. To prevent loss of the rate code signal during a phase jump, an improved rate code decoding system is provided wherein a correlation process is applied to the received rate code signal by multiplying the signal in separate multipliers with reference signals which are in quadrature and then cross-correlating the output of the multipliers with a step function and summing the absolute values of the outputs of the cross-correlators to provide a level which is substantially constant in the presence of a phase jump. The cross-correlation system provides a filter with a response which is effectively rectified by removing the notch which otherwise would result in the presence of a phase jump. The system may include means for decreasing the time required for the system to acquire the rate code signal when it first appears and in the presence of multiple phase jumps which occur in rapid succession. The system is especially suitable for use in railroads having short track circuits subject to phase jumps in the received rate code signals, for example, when the train travels along the tracks at high speeds.

摘要： A train having at least a pair of control cabs spaced along the train interconnected electrically. Electric signals transmitted between the control cabs allows for fluid braking signals to be propagated from both control cabs toward each other. Each car of the train includes a device for modifying a test signal transmitted between the control cabs in response to a specified condition. The signal modify device can be a tuned circuit and may indicate brake status or a hot journal.

摘要： A polarity sensitive relay fabricated of and controlled by, solid state components is provided to produce a more trouble-free and smaller device. The relay may be made in first and second versions, the first of which responds to input signals of a single polarity and the second of which produces first and second output signals in response to input signals of first and second polarities, respectively. The relays include first or second Wiegand modules each of which has a drive coil, an input signal coil and an output signal winding. The Wiegand modules are placed in a steady state magnetic bias and the drive coils pulsed at a predetermined frequency. When two modules are used, the input signal coils are connected in series and in a manner to produce opposite magnetic effects on their associated Wiegand modules. One or the other of the output signal windings will produce a stream of pulses, at the frequency at which the drive coils are driven, in response to a signal of one or the other polarity in the input signal windings. An appropriate magnetic shield is provided to prevent magnetic interference to or from nearby components. A disclosed embodiment is designed to be fail safe meaning that a component failure will not result in an output signal. The relays will not respond to an input signal below a predetermined magnitude.

摘要： A switch machine operates a track switch under radio control via a switch controller. The switch controller may be given an identifying address unique to it which distinguishes the switch machine from other switch machines in the railway territory. In addressing or programming the switch machine, a portable terminal is used. The controller is enabled by a manually actuable switch to accept identifying addresses which is stored in electrically erasable programmable read-only memory (EEPROM). Whenever a message is received over the radio link, the identifying address is read out of memory. In order that the identifying address is vital (fail-safe) and to guard against any errors which change the identifying address and which can cause the controller to effectuate operation of the track switch in front of an oncoming train or when the train is over the switch, the address is stored in the EEPROM by encoding the identfying address into unique multi-bit check words. Whenever a request to read the address is received by the switch controller, an attempt is made to write check value words, the value of which is equal to the difference between the value of the unique check words and the check words. A check value word replaces a unique check word in the event of a failure in the EEPROM or its addressing logic. The check value is also read into a check word register. The content of the check word register and the location in EEPROM for the check word under test is read into exclusive or gates. If there is a failure, the output of the array is a word having a value of zero, whereas if there was no failure the result of the exclusive or operation will be a word having the value of the check word. These check words are used in providing a vital output message for controlling the track switch and to provide and acknowledge message for transmission over the radio link to the central office of locomotive which communicates with the railway track switch controller. The switch is powered only when a vital output representing a desired switch operation (throwing the switch to normal to reverse or vice versa) is called for over the radio link.
