A method and apparatus for mitigating communications interference between satellite communications systems in different orbits is disclosed. The method comprises the steps of evaluating a geometrical relationship between a second ground station and the satellites in the second satellite constellation, and directing communications between the second ground station and the second satellite according to the evaluated geometrical relationship. In one embodiment communications are handed over from a first satellite to another satellite when the first satellite is no longer at the highest elevation angle of visible satellites. In another embodiment, handover occurs when the first satellite drops below a minimum elevation angle.

A hands-free personal hydration delivery system has a tubing assembly that has one end that detachably connects to a feed tube for a container of fluid worn on the back or torso of a user. The other end of the tubing assembly is coupled to a bite valve which is opened when manipulated by the user's mouth to allow fluid to be drawn by suction applied by the user, and is closed when not being manipulated so as to cut off fluid flow in an air-tight condition. An intermediate portion of the tubing assembly is mounted on the user's head or to the user's headgear at a position of higher elevation than the user's mouth. This allows fluid to be drawn to the elevated position and flow downward from there to the user's mouth by gravity feed. The fluid flow can then continue with little suction effort due to the gravity feed and siphoning effect of fluid from the container. The tubing can be mounted using retainer loops or other type of fasteners attached to a helmet, sports cap, head band bracket, headphone bracket, headband, or an earpiece worn by the user. The hydration delivery system is especially useful for bicycling, canoeing, mountain biking, kayaking, canoe paddling, and rowing environments.

A fluid catalytic cracking process includes feeding hydrocarbon into a riser in the presence of a catalyst, cracking the hydrocarbon in the riser in the presence of the catalyst to form a cracked stream, and separating the catalyst from the cracked stream. When in a gasoline mode, the hydrocarbon is fed through a first distributor into the riser, and when in a light olefin mode, the hydrocarbon is fed through a second distributor into the riser. The second distributor is positioned at a higher elevation than the first distributor.

A method of communicating satellite tracking information among a network of global navigation satellite system receivers is described. The method includes determining at a first GNSS receiver which satellites in a constellation of satellites have been continuously tracked over a preceding selected time period, and for each such satellite determining its elevation with respect to the zenith. Only the elevation value for the lowest satellite in the set of satellites for which all satellites of higher elevation values have been continuously tracked over the selected time period is then transmitted to the second GNSS receiver. That receiver can then reconstruct the set of satellites which have been continuously tracked.

A mobile receiver is programmed with available channels by initially searching for all potentially available channels and autoprogramming the receiver with channels that are detected by the receiver. Subsequently, only potentially available channels that have not been programmed into the receiver are searched for to reduce autoprogramming time when, e.g., the mobile receiver is carried to a higher elevation.

An input chamber receives runoff water to be cleaned. Part of the way up the chamber wall is a restricted outlet which feeds a system for cleaning the water. At a still higher elevation another opening allows runoff water to flow to an extended detention chamber. Near the top of the chamber is an outlet pipe. A vertical baffle in front of the outlet cleans water that flows under the baffle on its way to the outlet. When the incoming flow rate is very high, water passes over the baffle to the outlet.

A loader boom arm for a material handling vehicle used in the agricultural or construction industries includes a post attachable to the vehicle, a lower arm pivotally connected to the post, an upper arm pivotally connected to the lower arm, a pivoting mechanism coupled to the post and the lower arm, and a link arm pivotally connected to the post and to the upper arm. The boom arm is raised and lowered in an angular direction of rotation by pivoting the lower arm about the post using the pivoting mechanism. As the lower arm is pivoted, the link arm causes the upper arm to pivot relative to the lower arm such that the upper arm pivots further in the direction of angular rotation than the lower arm, thus changing the angle between the lower arm and upper arm. The subject loader boom arm allows an operator to move material in a bucket attached to the boom arm to locations of higher elevation and further reach than typically available with conventional boom arms.
