Abstract: The adaptive brake application and initial skid detection system allows rapid brake application and prevents deep initial skids. Brake torque is compared with a predetermined threshold brake torque. Wheel velocity error signals are also generated to indicated the difference between the wheel velocity and a reference velocity signal. A torque bias modulator integrator responsive to brake torque signals adjusts the wheel velocity error signals to provide an anti-skid control signal. The torque bias modulator integrator can also be initialized to the value of the measured brake torque when the wheel velocity error signals indicate the beginning of a skid. Brake torque difference signals are generated to indicate the difference between brake torque and a commanded brake torque, and an adjusted brake torque error signal is generated in response to the brake torque difference signals.

Abstract: The present invention provides for a vending system wherein a monitoring system verifies that a beverage product ordered by a vending customer is actually delivered through a delivery area to the customer. If the beverage product ordered is unavailable either because of an out of stock situation or a blockage of the delivery path for that product, the present invention allows the customer to request a refund or order a second product.

Abstract: A power controller is positioned within a current path between the line side and the load side of an electrical circuit. The power controller closes the current path in the presence of a control supply and opens the current path in the absence of the control supply. A power supply electrically connected to the current path provides the control supply. A sensor system receives power from the power supply, monitors the current in the current path and outputs a sensor signal indicative of a current condition within the current path. A logic controller also receives power from the power supply, receives the sensor signal and removes the control supply from the power controller when the sensor signal does not satisfy an established criteria. The sensor system may include one or both of an imbalance sensor for monitoring the current balance among two or more electrical lines and over-current sensors for monitoring current in individual lines.

Abstract: A combination crane A is formed by connecting two crawler cranes 1L and 1R. Each crawler crane is provided with at least a lower propelling body 3 which can propel by crawlers 2, an upper revolving body 5 rotatably mounted on the lower propelling body 3 by a swing unit 4 provided between them, a boom 6 of which base section is tiltably supported on the upper revolving body, a tilting mechanism 10 that raises and lowers the boom and a hoist mechanism that hoists and lowers the lifting members 12 hung by a hoist rope 11 from the top of the boom. Both upper swing bodies of two cranes are connected together with a connecting beam 20. Swing motion is performed by driving the one crawler crane to propel around the other crawler crane which is free to rotate and is locked to propel. The combination crane can change the direction of the body, and can increase the lifting capacity twice as much without troubles, and can be embodied easily.

Abstract: A traveling crane according to the present invention includes a hook hoisting guide sheave for guiding a hook hoisting rope from the top of a boom toward the end of a jib, and the hook hoisting guide sheave is arranged on the top of the boom in a state that the guide sheave can guide the hook hoisting rope along the upper surface of the boom by folding the rope toward an upper spreader placed at a position adjacent to a boom anchor during assembling/disassembling of the crane. Thereby, the upper spreader can be moved between the boom anchor and a far end of the boom without providing a guide sheave dedicated for moving the upper spreader. Pairs of support legs are downward provided on both sides and in front and in rear of the upper spreader and a roller is provided for each support leg, so that interference between the upper spreader during movement and obstacles on the boom upper surface can be prevented even in a horizontal movement system excellent in operating efficiency.

Abstract: A collision handling receiver for use in a data communication network. The collision handling system and method comprises collision handling receivers together with transmitters inserting pseudo-random delays. Accordingly, multiple sources may transmit simultaneous messages to a receiver so that the messages arrive with varying signal levels and times of arrival. The receiver sorts the symbols into separate sequences by grouping together symbols having similar time of arrival. In addition, the receiver retains the sequences with sufficiently reliable symbol detection, for example, when 75% of the symbols in a sequence are detected with sufficient quality. Receiver then ranks the retained transmitters by received signal level and decodes the messages from transmitters with highest received signal level.

Abstract: A system and method for iterative sequential carrier acquisition for estimating and correcting large carrier frequency offsets without adding significantly to receiver complexity or preamble length. A coarse frequency estimation is performed during a brief carrier acquisition phase that is completed during a reasonably short preamble, and then the system hands frequency control to the nominal carrier frequency & phase tracking of a phase-locked loop (PLL) circuit. The present disclosure generally includes an initialization mode, a pre-lock scan mode, an iterative search mode and a termination mode.

Abstract: In a crawler vehicle according to the present invention, at the time of crane operation at a place where a grounding space of crawlers is limited, a land leveling preparation is suppressed as less as possible so as to improve efficiency of the operation. The crawler vehicle according to the present invention has a high performance. The crawler vehicle according to the present invention is provided with a pair of left and right crawler frames on the both left and right sides of a track frame. The crawler frames can be moved between an expansion position for maximizing a distance between centers of the crawlers and a contraction position for minimizing the distance. Further, the crawler vehicle according to the present invention can position the crawler frames to the track frame at an intermediate position in the middle of the expansion position and the contraction position.

Abstract: At an inner circumference side of a lower ring and an upper ring, flange pars are formed respectively, and a ring-shaped clamp device is arranged at the inner circumference side, and separated at four points, into a front side, back side, left side, and right side, and divided into four divided clamps. At the separation points of front and back sides, the left and right divided clamps are rotatably connected with each other, and at the separation points of left and right sides, the front and back divided clamps are connected to cylinders respectively. By the extension/contraction operation, the front and back clamps move between joint and separation positions, and if the front and back clamps position at the joint points, predetermined spaces are formed between the divided clamps. Lock blocks to be inserted into the spaces for regulating return of the divided clamps to the separation positions are provided.
