Title: Automotive floor liner
Inventor: NIEMI KARL A
IPC: B60N3/04
Filed: 1994-08-15
Granted: 2005-02-01
Abstract: Protection for the rear carpet areas of an automobile such as a sport utility vehicle is provided by a unitary sheet of heavy-gauge extruded, high-density polyethylene. The floor liner has a floor panel which covers the floor of the cargo area of a sports utility vehicle. The floor panel has sides which extend along and are tucked under the wheel well trim panels on either side of the cargo area. Integrally formed with, and attached to, the forward edge of the floor panel, are two cargo extension panels. The cargo extension panels form a continuation of the forward edge of the cargo floor panel and are separated from each other by a seat back accommodation slot. This slot divides the cargo extension panels so that each panel corresponds to the width of the seat back positioned forward of each panel. Continuing on from the cargo extension panels are recumbent panels which are integrally formed with and joined to the cargo panels. These in turn are joined to integrally formed seat back panels. The joints between the panels are of the type known as a "living hinge" and are cold-formed into the material of the liner itself. The double living hinges provide resilient, long-life hinges impervious to liquids and provide flat extended edges of unproved appearance and safety. The spring-loaded extension panel of a vehicle urges the seat back panel against a seat back and hence retains the liner without additional fasteners.

Title: Pressure-fit gate assembly
Inventor: ASBACH RONALD M
IPC: E05C1/10
Filed: 1994-10-25
Granted: 1999-01-26
Abstract: A safety gate that has a continuously adjustable width for insertion across a lateral opening such as a doorway. The gate has a generally U-shaped gate frame including two tubular frame members that are slidably connected in a telescoping relationship. A latch is operable to displace the telescoping portions by a pre-selected displacement relative to each other, so that part of the tubes are deflected and the gate frame applies an outward lateral force to the doorway opening sides to retain the gate across the opening. The gate includes a walk-through door with a door latch for latching the door closed and an indicator for indicating when it is not fully closed and latched. A force-distribution bar on at least one side of the gate distributes the force from that side of the gate so that it is applied at two points on that side of the doorway opening.

Title: Multipath tolerant location system and method therefor
Inventor: ERICKSON BART J
IPC: G01S1/04
Filed: 1995-01-27
Granted: 2004-04-06
Abstract: A multilateration location system (12) includes a locatable unit (16) and any number of known-position locators (14). A time of arrival detector (22) determines instants in time when a location signal (20) transmitted by the locatable unit (16) arrives at various known-position locators (14). For each combination of two known-position locators (14) that receive the location signal (20), a pre-estimation process (32) determines whether the difference in arrival times is less than or equal to a maximum propagation duration for the locator pair. The maximum propagation duration is based upon the distance between the locators (14) in the locator pair. If the difference is greater than the maximum propagation duration, the difference is omitted from the data set processed by a multilateration calculation process (34). A post estimation filtering process (36) screens out location estimates that are too distant from a predicted position.

Abstract: Four-wave mixing between multiplexed channels in a wavelength division multiplexed optical transmission system, and the effects of polarization dependent hole burning, are simultaneously reduced, in accordance with the invention, by a method and apparatus which provides for modulating  a state-of-polarization of an optical signal, where the optical signal has a plurality optical channels, so that an average value of the state-of-polarization of the optical signal over each modulation cycle is substantially equal to zero; and, orienting states-of-polarization of predetermined optical channels of the optical signal in response to a signal indicative of a predetermined characteristic of the transmission system while maintaining the substantially zero average value of the state-of-polarization of the optical signal over each modulation cycle. Advantageously, this approach provides for a reduction in performance limiting effects under changing conditions.
