A multilayer film includes at least an abuse layer that is laser scored, and a sealant layer that has discrete weakened portions, due to the laser scoring. The multilayer film may have a tensile strength of between about 0.40 and 2.5 pounds per 10 millimeters at the location of the one or more weakened portions. In certain aspects, the tensile strength of the multilayer film is between about 7 and 14 pounds per inch at the location of the laser scoring on the abuse layer. Also, a package is provided that is formed from one or more multilayer films having a scored abuse layer and a sealant layer with weakened portions that allow steam and/or pressure to be vented from the package during heating. Optionally, the abuse layer includes a shallow scoring portion to provide an easy-open feature. For instance, the package may be used to cook frozen foods contained in the package, such as in a microwave oven.

A portable workpiece stopping device, attachable to a work surface relative to a primary tool, permitting a repetitive same-length operation to be performed on any number of workpieces, and which allows for interruption of the operation without affecting the essential positioning of the stopping device relative to the primary tool. The stopping device comprises a base plate selectively attachable to a work surface, a rotation plate rotatably coupled to the base plate, an alignment plate adjustably coupled to the rotation plate, a stop plate fixedly coupled to the alignment plate, and a support shelf adjustably coupled to the stop plate. The stopping device can be selectively transitioned from an obstructing position, which blocks the end of a workpiece pressed against the stop plate, thereby allowing the repetitive same-length operation to be performed, to a non-obstructing position which provides for unfettered positioning of any workpiece relative to the primary tool.

This invention relates to a scrub pad comprising a scrubbing layer having a periphery along the edges of the layer; a wiping layer having a periphery along the edges of the layer; and an absorbent core layer having a periphery along the edges of the layer comprising at least one absorbent material selected from the group consisting of short-fiber, air-laid nonwoven material, nonwoven plastic batting, cellulosic fibrous web materials, wax coated paper, corrugated paper, fluff pulp, cotton balls, cotton batting, or mixture thereof; wherein the absorbent core layer is located intermediate to the scrubbing layer and the wiping layer and wherein the scrubbing layer, the absorbent core layer and the wiping layer are joined at the periphery of each layer.

The present general inventive concept relates generally to an animal lift, and more particularly to a portable, lightweight ramp device with collapsible side panels to eliminate the visual cliff perceived by a user animal.

A form-fill-and-seal (FFS) packaging machine is described wherein a zipper is attached to the package simultaneously with the sealing operation at the sealing and evacuation station. The attached zipper is thereafter welded in place at the zipper welding and cutting station. A zipper blank feeder and a channel-forming die with an impulse sealer are integrated into the sealing die of a packaging machine forming a combination work station. The zipper is installed at an existing work station and shares the existing lifting device. This enables the retrofitting of an FFS packaging machine to include a zipper attachment function without changing the footprint thereof. The combination work station forms a channel for the zipper blank between the thermoformed web and the lidstock. While the sealing die is providing a seal about the lid, the impulse sealer in the channel-forming die attaches the zipper to an initial attachment portion of the packaging film. Upon completion of the package, this initial attachment portion, if retained, becomes the tamper-indication portion of the package. Both the sealing and evacuation station and the zipper welding stations of this invention are of jacketed construction enabling the temperature control of the zipper blank throughout the installation procedures.

A method is provided for determining the start and the end of an automatic braking process to optimize the triggering of the automatic braking process. When a set value is exceeded, an automatic braking process is triggered. The threshold value is changed as a function of the driving state, in particular, as a function of the speed of the vehicle when the brake pedal is actuated, and independently thereof, as a function of the position of the brake pedal. In addition, various criteria terminate the automatic braking process as a function of the actuation force of the brake pedal, of the speed of the vehicle and of the pedal travel.
摘要:
A method is disclosed for controlling the triggering sensitivity of an automatic braking process for a motor vehicle based on the driving behavior of an individual driver. A predetermined fixed threshold value of the actuation speed of the brake pedal is multiplied by a driver-dependent factor which is determined after each braking process, as a function of the actuation speed and of the pedal travel of the brake pedal, to generate a driver-dependent threshold for actuation of automatic braking.

A device monitors an automatic braking process by using a fault-detecting, operational testing method which takes place via an automatic braking process lasting only briefly, typically about 50 ms. The method is initiated by a test control device and can take place during different vehicle states. If, for example, current through a solenoid valve does not lie within specific acceptable limit values or pedal travel which results from the actuation is not determined at the brake pedal, the device concludes that an operational fault has occurred
