Abstract: A method for generating a prediction of a latency of a transaction processing system includes: sampling a first plurality of messages from a database that stores data indicative of messages previously processed by the transaction processing system including a characteristic and a processing time of each previously processed message; generating latency tables based upon the characteristics and the processing times of the sampled first plurality of messages; determining a characteristic of each of a second plurality of messages being processed by the transaction processing system; selecting, for each of the second plurality of messages, a latency table from the plurality of latency tables based upon the respective determined characteristic; simulating a processing time for each of the second plurality of messages based upon the respective selected latency table; and generating a latency prediction for the transaction processing system based upon the simulated processing times for the second plurality of message

Abstract: A ratchet drive winch for securing cargo to a transport vehicle includes a shaft rotatably mounted on the vehicle, the shaft receiving one end of a flexible tie down member. A lever arm, rotatably mounted on the shaft, controls a ratchet gear fixed to the shaft through a pawl. The lever arm pawl causes the shaft to follow the lever arm as it is rotated in one direction. A holding pawl mounted on the frame prevents the shaft from rotating in the opposite direction so that as the lever arm is moved back and forth the shaft is rotated removing slack in the tie down member. The lever arm pawl can be manually retracted to disengage from the ratchet gear and is configured to selectively retract the holding pawl allowing the shaft to freely rotate.

Abstract: An improved vehicle carrier having upper and lower levels for receiving a plurality of vehicles. The upper level of the carrier includes a rear table which can be tilted to provide a ramp for vehicles being loaded onto the upper level. Each rear table is lifted up and down by a pair of telescoping struts disposed on either side of the vehicle carrier. A rear pair of telescoping struts is directly attached to the rear table. Each one of the rear pair of telescoping struts is pivotably attached at a lower end to the chassis of the vehicle carrier and is pivotably attached at an upper end to the rear table. A forward pair of telescoping struts is rigidly mounted at a fixed angle to the chassis and has an upper end which is pivotably intermediately attached to a swing arm beam. A rear end of the swing arm beam is pivotably attached to a forward end of the rear table. A forward end of the swing arm beam is adapted with a slot to pivot and translate about a fixed pivot point on the chassis of the vehicle carrier.
