Abstract: An AC signal filter useful in a truck tractor equipped with power line communication for indicating in the tractor the status of an automatic braking system (ABS) in a trailer to which the tractor can be connected. The filter comprises a first power line carrying DC power connected between the tractor battery and a tractor ABS module. A second power line carrying DC power is connected from the tractor battery to a tractor connecting to a trailer ABS module. A first inductor is coupled in the first power line to block the passage of AC signals from the tractor ABS to the tractor battery, but permit the passage of DC current from the tractor battery to the tractor ABS module. A second inductor is coupled in the first power line to block the passage of AC signals from the trailer ABS module to the tractor battery but permit the passage of DC current from the tractor battery to the trailer ABS module.

Abstract: An apparatus for automatically identifying when an animal is in distress receives a sound pattern produced near the selected animal and compares it with pre-stored audio patterns corresponding to respective sounds expected to be produced by that type of animal when in various types of distress to determine the best match. When a good enough match is made, a signal is automatically sent to a remote communication unit near an attendant.

Abstract: An EAS tag in which the tag is held to an article by an attaching assembly a part of which is releasably prevented from being withdrawn from the body of the tag. The tag body is provided with an arcuate channel through which an arcuate detacher probe can be guided for releasing the attaching assembly part.

Abstract: A portable panel position detector for determining the orientation of panels being serially moved on a transfer line into a downstream panel treatment facility comprising a pair of support towers laterally spaced to allow the passage of line supported panels therethrough. The spaced support towers operatively mount elongated and vertically extending sensor strips in opposing spaced relationship that defines clearance-determining gating between the towers. In the event a panel moving through the restricted gate is not properly orientated on the transfer line, at least one sensor strip or a portion thereof will be deflected by physical contact with the panel moving therethrough. The displaced strip effects the triggering of an alarm that advises a transfer line attendant that the panel is improperly loaded. The panel can be appropriately repositioned on the transfer line so that it can successfully pass through the treatment facility without damage.

Abstract: The present invention provides an enclosure sign apparatus for unavoidable viewing of a sign before manipulation of an entryway opening device. The enclosure sign apparatus includes at least one side surface extending out as least as far as the entryway opening device, a back surface interconnected to the side surface, wherein the back surface comprises an opening to accommodate the entryway opening device therethrough, and a front surface having a sign. The front surface is capable of preventing access to the entryway opening device and is interconnected to the side surface. When in use, access is obtained to an entryway opening device by physically removing the enclosure sign apparatus so that there is unavoidable viewing of a sign before manipulation of the entryway opening device.

Abstract: A tire pressure monitoring system includes plurality of sensor modules having respective motion switches and pressure sensors respectively attached to the tires of a vehicle.

Abstract: An earth stratum flush monitoring method and a system thereof. Multiple transmitter units are embedded in the earth stratum at predetermined depth intervals. When the earth stratum is flushed, the respective transmitter units will be one by one flushed and displaced and shocked or rotated in accordance with the change of flush depth of the earth stratum. A shock sensor in each transmitter unit will sense this shock. The radio signal transmitters of the transmitter units will emit different encoded radio signals. A signal receiving apparatus disposed on the ground receives the signals and a computer reads the signals so as to monitor and know the real-time flush depth of the earth stratum. The detected real-time flush depth is then transmitted to an early warning unit for the early warning unit to read and judge and emit an alarm in time.

Abstract: The present invention relates to a method for regulating clearance for a vehicle, in which a relative velocity (vrel) and a relative distance (a) between the vehicle and a second vehicle driving ahead are detected, and a control signal for an adaptive cruise control device is generated from these quantities. The control signal being derived from a danger criterion (G) is determined from the relative velocity (vrel) and the relative distance (a), this danger criterion which is weighted with an adaptive factor (AF) representing the individual driving behavior of a vehicle driver, and a control signal initiating a deceleration of the vehicle is generated when the danger criterion (GF), weighted with the adaptive factor and adapted to the vehicle driver, falls below a defined threshold value (S).

Abstract: An apparatus for monitoring and controlling the operation of an electrical power transformer includes a processor with input transducers for providing to the processor inputs indicative of electrical current in a winding of the transformer and ambient temperature outside the transformer. The processor is arranged using an algorithm based upon heat transfer to repeatedly calculate a first prediction, based upon the present values of electrical current and ambient temperature, of a time period before the hot spot temperature exceeds a pre-set allowable maximum and a second prediction, based upon the current value of power, of a time period before the accumulated loss of life exceeds a pre-set allowable maximum. If the shorter time period of the two calculations is less than a pre-set value, for example one half hour, the processor generates an alarm signal and a display counting down the time remaining in the period, together with a second alarm signal at a shorter second time of for example one quarter hour.
