Filed: 1993-01-08
Abstract: A hinge assembly for hingedly connecting a cover (106) and a housing there-together, such as a keypad cover and a housing of a portable radiotelephone (112). A generally tubular hinge arm (124) is formed at an end portion of the cover (106), and two hinge pins (136, 148), each having identical cam surfaces formed upon edge surfaces thereof, are inserted into the hinge arm (124) and positioned suchthat the cam surfaces of the respective hinge pins (136, 148) extend beyond oppos-ing sides of the hinge arm (124) such that the hinge pins (136, 148) are caused to rotate in unison with rotation of the cover (106). A spring member (142) is tandem-ly-positioned between the two hinge pins (136, 148) to exert spring forces thereup-on. Two cam followers (154) are affixed to the housing in a manner such that thecam surfaces of the hinge pins (136, 148) abut against the cam followers (154). The cover (106) may be rotated between an opened and a closed position and forces ex-erted upon the cam surfaces of the hinge pins (136, 148) by their abutting engage-ment with the cam followers (154) urge the cover (106) into or out of the open and closed positions during rotation of the cover (106) and urge the cover (106) to re-main in the open or the closed position in the absence of rotational moments exert-ed thereupon by the spring forces exerted upon the hinge pins (136, 148) by the spring member (142).

Title: Intelligent foot appliance
Inventor: GROSS CLIFFORD
IPC: A43B5/06
Filed: 1993-09-09
Abstract: A foot appliance (10) comprises a sole (12) and side walls (14) forming a load bearing surface for a foot. A plurality of air bladders (19-26) are located within the load bearing surface. The feedback system comprises a sensor apparatus for generating data indicating an actual distribution of load exerted by the foot on the load bearing surface.

Patent CA-2123449-A1 (CA)
Inventor: ALFONSI JEAN-PIERRE
IPC: H04L12/56
Filed: 1994-05-12
Abstract: Currently, the routing algorithms compute all the available paths in the network, from the source node to the destination node before to select the optimal route. No assumption is made on the network topology and the route computation is often time and resource consuming. Some paths which are calculated are not acceptable due to the particular geographical configuration of the network. In the real world, large transport networks are not fully meshed. The present invention is based on the observation that networks are usually built around a hierarchical structure. A set of nodes, interconnected by high throughput lines, are used to build a 'Backbone' (401) with a high degree of meshing to allow the redundancy and reliability required by the user. The other nodes or 'local' nodes (404) are attached to one or several backbone nodes. It is the network designer responsibility, at the configuration time to define for each node what is its attribution: backbone (402) or local node (404). The list of the node attributions appears in the topology table (306) and is updated each time a node is added to or dropped from the network. The routing algorithm can take advantage of the particular network topology to drastically reduce the complexity of paths computation. For a given connection, only a limited number of nodes are eligible and are taken in account by the algorithm in the optimal route search. The object of the invention is to split the network in backbone and local nodes to speed up the path selection.

Filed: 1994-07-04
Abstract: A method and apparatus for monitoring oil charge loss for use with a refrigeration system. The refrigeration system has a compressor for compressing a refrigerant gas, an oil/gas separator for separating compressed refrigerant from lubricating oil, a condenser for condensing the compressed refrigerant gas, an oil cooler for cooling oil separated from the refrigerant, the refrigerant and oil both having known and differing coefficients of heat transfer, and an injection system for injecting the cooled oil into the compressor. The method includes the steps of:     a. determining the difference in temperatures of oil cooled in the oil cooler and refrigerant cooled in the oil cooler based on the known coefficients of heat transfer of the refrigerant and the oil and the cooling capacity of the oil cooler; b. sensing the temperature of the liquid in the oil cooler; c. sensing the temperature of the saturated refrigerant in the condenser; d. comparing the temperature of the liquid in the oil cooler and the temperature of the saturated refrigerant in the condenser; and e. generating a signal to shut down the compressor when the comparison of the temperature of the liquid in the oil cooler and the temperature of the saturated refrigerant in the condenser indicates that the liquid in the oil cooler is refrigerant or if the oil temperature is excessive.

Title: Graphs employing clusters
Inventor: NORTH STEPHEN C
IPC: G06T11/20
Filed: 1994-08-18
Abstract: Abstract Techniques for automatically laying out directed graphs with clusters. The techniques produce pictorial representations of the graphs which are easier to understand, more pleasing, and more compact than those produced by the prior art. The techniques have been added to the well-known DOT system for laying out directed graphs, and include a recursive technique for ranking nodes of the graph, a technique for ordering nodes within ranks which collapses subclusters into skeletons when the nodes within a cluster are ordered, and a technique for positioning thenodes after they have been ranked and ordered which obtains the x coordinates for the nodes by producing an auxiliary graph which is in effect the original graph "turned on its side" and assigning ranks to the nodes in the auxiliary graph.

Title: Adaptive time-division multiplexing communications protocol method and system
Inventor: ROCHESTER VIRGIL M JR
IPC: H04L12/56
Filed: 1993-04-29
Abstract: A system and method for an adaptive time-division multiplexing communications protocol for collecting data from remote sensors equipped with RF transceivers using an RF transceiver equipped mobile data collection unit. RF transceivers interfaced to remote sensors actively monitor a predetermined RF transmission frequency to ascertain the presence of a signal transmitted by the mobile unit. All remote units detecting the RF signal listen for a message from the mobile unit requesting transmission of their unique identifier, i.e., their ID. This message contains the Time Division Base (TDB) specifying the number of time slots al-located for transmission of remote sensor IDs to the mobile unit. Using the TDB, each remote sensor randomly selects a time slot and transmits its ID to the mobile unit. Unique IDs of remote sensors received by the mobile unit are used to individually poll each sensor for data packet transmission. Upon receipt of a data packet from a remote sensor, the mobile unit sends an acknowl-edgment packet indicating its data has been received. Upon receipt of the acknowledgment packet, the sensor is set to a state whereby it will not respond to a request for identifier for a specified period of time.
