Title: Mobile satellite user information request system and methods
Inventor: WIEDEMAN ROBERT A
IPC: H04W24/02
Filed: 1999-05-13
Abstract: A method in accordance with this invention for operating a satellite communications system of a type that has a plurality of earth orbiting satellites, at least one terrestrial user terminal, and at least one terrestrial gateway, includes steps of determining a location and an azimuthal orientation of the user terminal; determining locations of one or more satellites co-visible to the user terminal and to the gateway; determining a signal quality of paths to each satellite co-visible with the gateway; displaying a representation to an operator of the user terminal, the representation depicting at least the orientation of the user terminal, the determined locations of the one or more satellites, and the determined signal qualities for satellites that are in use and those that are not in use; and changing the location of the user terminal in response to the displayed representation. Also, an unattended user terminal located a desired geographical position can generate a map of the sky over a period of time, the map indicating satellite availability at the desired position. The map can subsequently be used by the user terminal and/or the gateway to schedule communications, thereby conserving one or both of system capacity and user terminal battery power.

Patent CA-2278793-A1 (CA)
Inventor: KALMAKIS GEORGE P
IPC: G01N35/10
Filed: 1997-12-31
Abstract: A pipettor including a body portion, a cylinder having an interior channel, and a filter plug disposed within the channel is disclosed. The filter plug may include a plurality of pores and may preferably be treated with a first chemical, so as to affect closure of the pores when the filter plug contacts a pipetted fluid. The pore closure helps contain leakage of the fluid into the pipettor by sealing the pipettor to addtional fluid flow. The filter plug may also be treated with a second chemical to affect a change in the color of the filter plug upon contact with the pipetted fluid. The color change acts as a signal to an operator that possible contamination of the pipettor has occurred. The color change and/or closure may also be affected by an aerosol generated from the pipetted fluid.

Inventor: MAHADEVAN RAMASWAMY
IPC: G02B6/38
Filed: 1998-08-28
Abstract: A MEMS actuator is provided that produces significant forces and displacements while consumming a reasonable amount of power. The MEMS actuator includes a microelectronic substrate, spaced apart supports on the substrate and a metallic arched beam extending between the spaced apart supports. The MEMS actuator also includes a heater for heating the arched beam to cause futher arching of the beam. In order to effectively transfer heat from the heater to the metallic arched beam, the metallic arched beam extends over and is spaced, albeit slightly, from the heater. As such, the MEMS actuator effectively converts the heat generated by the heater into mechanical motion of the metallic arched beam. A family of other MEMS devices, such as relays, switching arrays and valves, are also provided that include one or more MEMS actuators in order to take advantage of its efficient operating characteristics. In addition, a method of fabricating a MEMS actuator is further provided.

Abstract: This maintenance trestle (10) is, as shown by a dashed line, stowable in folded-together form at the hatch cover (14.1). For erection of the maintenance trestle (10), the hatch cover (14.1) is tilted into the lift cage (2) about a first fulcrum (D1). The maintenance trestle (10) is now accessible in folded-together form for the erecting. Firstly, several supports (10.1) arranged in cage walls (2.1) are pivotable into the lift cage (2) and transverse connectors (10.3) are arranged at the supports (10.2). The transverse connectors (10.3) carry plates (10.11) forming the platform (10.1). For stabilising the maintenance trestle (10), diagonally extending stays are arranged between the supports (10.2) and a cage floor (13). With the maintenance trestle (10) in work setting, the safety of the engineer (17) is taken care of and the prescribed over-travel (~) achieved, because the distance between the cage ceiling (1.1) and the platform (10.1) is determinative for that.

Abstract: A vacuum coated, liquid impermeable, vapor permeable laminate article and a method for making same are disclosed. The laminate may be formed of a netting material which is coated with a thin layer of vapor permeable polymer and subsequently passed over a vacuum forming drum to draw the polymer coating downward into the openings in the netting material. Vacuum coating produces thinned regions in the coating layer which provide greater vapor permeability. In laminates with sufficiently large openings in the netting material, the coating may directly contact a vacuum forming screen resulting in a plurality small indentations or cells within a single thinned region of the liquid impervious coating further increasing vapor permeability.
