Title: Call processing using logical channel assignments
Inventor: WANG THERESA C Y
IPC: H04L12/56
Filed: 1993-02-08
Abstract: A communications network includes satellites, which serve as switching nodes and move in orbits about the earth. The network additionally includes stationary switching offices. Mobile communication units communicate with the network through the satellites using TDMA data packets and network control messages.      The switching offices couple to PSTNs. Each mobile unit is managed by a nearby switching office that assigns a logical channel identification (LCID) value to the unit.      The unit and network use the LCID value to identify the unit in network communications so that network resources are conserved. The network insures that LCID values assigned to opposing parties in a call are included in all TDMA data packets transported to the opposing parties. Satellites and switching offices use these LCID values as logical channel assignments which do not change throughout the duration of the call, in spite of movement by satellites.

Title: Hybrid inflator
Inventor: CHAN SEK K
IPC: B60R21/26
Filed: 1993-03-03
Abstract: ABSTRACT HYBRID INFLATOR The Invention provides a hybrid inflator for a gas bag safety restraint system for use in a motorized vehicle wherein a compressed supply of stored inert gas is heated by means of a pyrotechnic material in sheet form. The sheeted pyrotechic material may advantageously be located within the compressed gas storage vessel in a thin container or in direct contact with the gas. The invention also includes a heating element for a hybrid inflator.   The preferred pyrotechnic material comprises a substrate of an oxidizing polymeric material for example, polytetrafluoroethylene (PTFE), coated with an oxidizable material, for example magnesium, which is capable of reacting exothermally with the oxidizing polymeric material.   The invention facilitates simple, cheaper constructions of hybrid inflators and the pyrotechnic sheet produces solid products in very fine particle form which gives improved energy transfer to the stored gas.

Title: Residential refuse collection cart lifter with universal features
Inventor: BAYNE JIMMY O
IPC: B65F3/10
Filed: 1993-06-17
Abstract: ABSTRACT OF THE DISCLOSURE A lifter automatically adapts to pick up different style residential refuse collection carts.  An upper movable clamp bar cooperates with a finger support bar to grab a smooth-sided cart with a single upper lifting lip.  A hinged saddle and hinged sliding hook lifts carts having a pair of opposing engagement surfaces (e.q., bars).  Hinged members are automatically pivoted into retracted positions during presentation of smooth sided carts, but are otherwise maintained in place for engaging other type carts.  The lifter has a relatively short face plate for size and weight advantages, obtained by alternate extension/retraction of the hinged sliding hook during a lift cycle.  Rollers on the extending face plate prevent cart scarring.  Adjustment for different height carts is provided by a vertical lift assembly which uses a hydraulic seguencing valve to first raise the lifter for engaging the cart and then to cycle through a dumping process.  Vertical lift adjustment uses a pair of guide rods with pairs of slip fit bushings for improved dynamic operational stability.  A movable valving member is engaged by a piston for automatically reducing the flow rate of hydraulic oil as the. piston nears the end of its cycle, i.e., as a cart is being fully inverted and dumped.  Such action dampens cart and apparatus wear and strain.  The piston responsive variable valving features are also useful with devices other than cart lifters.

Patent CA-2105852-A1 (CA)
Inventor: LECUN YANN A
IPC: G06V30/10
Filed: 1993-09-09
Abstract: Data samples describing a plurality of micro-segments that compose a symbol to be recognized are received from a device (10) such as an electronic pad. A preprocessor (12) maps the micro-segments into cells of an array that has several feature dimemsions. The preprocessor assigns values to the cells based on the length of a micro-segment associated with the cell, and how well the features of the associated micro-segment correspond to the feature label of the cell. The cell values are used as inputs to a neural network (14) that identifies the symbol. In one embodiment, recognizing symbols from large groups of symbols is facilitated by using a plurality of neural networks. Each neural network is trained to recognise symbols from a different subgroup of symbols, and each neural network can determine whether the symbol belongs to its subgroup. FIG. 1.

Abstract: A harrow comprises an elongate tool bar formed in three sections including a central section and two wing sections all of which can rotate about a longitudinal axis. The wing sections are coupled by pivot couplings which allow the wing sections to fold rearwardly in the transport position. The tool bar carries a number of harrow elements each of which is formed by a rigid frame defined by longitudinal rails and welded cross bars with the frame carrying a plurality of tine support bars. A push rod simultaneously rotates all of the tine support bars about their respective axis to vary the angle of the tine in contact with the ground. The angle of the tines of all of the harrow elements are adjusted simultaneously by a number of rocker shafts mounted on the tool bar and operated by rephasing cylinders. Each push bar of each harrow element is attached to the respective rocker shaft for actuation. The harrow frame is mounted on a bracket passing underneath the square section tool bar and pivots about a horizontal axis just rearward of the tool bar with tension springs forwardly of the tool bar pulling the frame upwardly. The tool bar can be rotated beyond the horizontal position to apply downward pressure on the harrow frame against the ground.
