Title: Aircraft landing gear swivel locking pin having automatic release and reengage
Inventor: DEL MONTE BERARDINO
IPC: B64C25/50
Filed: 1993-09-24
Abstract: An aircraft landing locking pin (12) automati-cally repositions from an engage position, wherein a rotating portion (15) of the landing gear is prevented from rotating, to a released position, wherein the rotat-ing portion if free to rotate, in response to excessive side loading on the landing gear. The locking pin com-prises a spring loaded actuator (32, 34, 60) which urges a roller (19) of a lock pin assembly (20) in con-tact with a bushing (22). In response to a side loading on the landing gear in excess of a predetermined load-ing, the locking pin is automatically released wherein the roller is expelled from the bushing. The threshold loading is determined as a function of the spring force applied to the lock pin assembly via the actuator lin-kage. The locking pin automatically reengages when the lock pin assembly is aligned with the bushing.

Title: Speed indicator for marine vehicles
Inventor: CALLIHOO BRIAN
IPC: G01P5/07
Filed: 1995-03-14
Abstract: A speed indicator for marine vehicles is mounted on the lower transom area of such a vehicle and includes an impeller. The impeller rotates at an angular velocity dependant on the speed of marine vehicle relative to the water. A mounting bracket secures the speed indicator to the marine vehicle in a manner to permit movement of speed indicator relative to the marine vehicle so that the axis of the impeller remains generally in line with the direction of travel of the marine vehicle. To try to ensure laminar flow across the impeller and to facilitate movement of the speed indicator, the speed indicator has a guide vane positioned upstream of the impeller. The mounting bracket also permits adjustment of the speed indicator so that the axis of the impeller is basically parallel to the plane of the bottom of the marine vehicle.        A sensor including a magnetic conductor and a magnetic pick-up detects rotation of the impeller and generates output representative of the speed of the marine vehicle. In one embodiment, the magnetic pick-up is supported by the speed indicator above the water level.
Patent CA-2144998-A1 (CA)
Inventor: MALONEY PAUL J
IPC: A01M29/02
Filed: 1995-03-17
Abstract: This invention relates to a series of physical pest control devices, herein referred to as responsive guards, designed to effect an instinctive flight response in an approaching pest animal. Existing guards include scarecrows, plastic owls, owl-eyed balloons, sharp-spiked anti-bird materials, and electric fences. These existing guards neither sense nor respond to an approaching pest in that they are immobile. The invention, herein referred to as responsive guards, show improvements to existing guards. Consequently, the usefulness of guards is now expanded in new applications for control of other types of pests. The embodiment of this invention is the incorporation into a guard of a true sensor (not just a trigger) in turn connected to another device to produce a stimulus. An array of design models incorporate different guard images and stimuli to suit specific pests and applications. One responsive guard design incorporates a traditional scarecrow for protecting home gardens from squirrels. Here, this responsive scarecrow senses an approaching squirrel which consequently activates a built-in irrigation system. The pest instinctively takes flight from this sudden spray and life-like stimuli. Other design models include responsive guards in the form of raptors (birds of prey) that may respond in any number of ways (e.g., attacking crys, flapping wings, movement on a guide wire, glowing of eyes). Again, other guards may not have a form of any particular importance, but simply be a response for a particular circumstance. For example, a garbage pail responsive guard responds to approaching raccoons with a repellent spray. In another, pigeons take flight from a roosting site when a responsive guard projects owl-eye images.

Abstract: Methods for handoff in a wireless communication network comprised of a local area network connected to a plurality of base stations, each of which has a geographic area, defined as a cell, within which mobile stations can communicate with a base station, with each such base station being capable of performing bidirectional wireless communication with one or more of said mobile stations under control of a controller, with communication between base stations and mobile stations being performed by frequency hopping, with there being n available frequency hopping channels in a fixed frequency band, with each channel being of a same fixed duration and having a fixed frequency different than another channel. The handoff method employs structure and techniques for determining by a mobile station that the quality of transmission between it and a current base station has degraded below a predetermined performance level, structure and technique for said mobile station to listen to each of successive frequency channels for a duration substantially less than said fixed duration of a channel until it senses a transmission from another base station, and structure and techniques for transferring control of said mobile station to said another base station in response to the sensed transmission.
