Abstract: A tow bar having a towing connector for releasably connecting a first hitch arrangement of a towing vehicle to a second hitch arrangement of a towed vehicle includes a pair of opposing legs, each leg having a fore section connected to the towing connector and an aft section connected to the second hitch arrangement, a pivot connector pivotally connecting the fore section to the aft section, a locking mechanism for converting the respective leg from an aligned tubular structure for towing purposes to an articulated structure for on-vehicle storage purposes, and a hanger for retaining the tow bar in a stored configuration. An auxiliary locking mechanism operatively prevents the legs from pivoting relative to the towing connector while the towed vehicle is being towed.

Abstract: A steering stabilizer includes a device connecting a fixed part of a vehicle to a steering mechanism of the vehicle, a control mechanism, and a centering mechanism. The control mechanism, which normally maintains an equilibrium configuration, includes a first member connected to a cylinder portion of a gas spring and a second member secured to a rod portion of the gas spring. A centering mechanism maintains alignment of the gas spring with the device. When the stabilizer is extended from the equilibrium configuration, the gas spring is activated to responsively and automatically return the stabilizer to the equilibrium configuration; and when the device is compressed from the equilibrium configuration, the gas spring is activated to responsively and automatically return the stabilizer to the equilibrium configuration.

Abstract: A method of and system for inspecting multi-layer reticles. The method includes: selecting a multi-layer reticle having an array of cells arranged in R rows and C columns; defining a full inspection region that includes all cells of the array of cells; and when R is equal to one (or is greater than two) and C is greater than two (or is equal to one) and a cell of the array of cells is a dummy cell in a first or last position of a row (or of a column) of the array of cells, then reducing the full inspection region to generate a shrunken inspection region that does not include the dummy cell, and then inspecting the shrunken inspection region for defects. If the dummy cell is between two non-dummy cells, then the dummy cell is a copy of one of the non-dummy cells, but is not inspected.

Abstract: To manage a fleet of vehicles efficiently, data is obtained concerning vehicle condition; some of this data is recorded in a data packet format on a vehicle and transmitted by radio from the vehicles to a base station, and under some circumstances, transmitted by the internet to a central data station where it is used to determine what should be done with the vehicles, such as for example to determine if the battery of a vehicle must be charged. The data may be transmitted from one vehicle to another vehicle before reaching the base station or the central data station. The data packets can indicate the vehicle to which the data applies, if the battery needs to be charged or replaced and can establish a priority schedule for the charging or replacement of the battery.
