Patent CA-2282229-C (CA)
Title: Conversion kit for creating an obstacle-mounting wheelchair
Inventor: NICHOLS DEREK
IPC: A61G5/06
Filed: 1999-09-16
Granted: 2004-12-07
Abstract: A kit for converting a conventional wheelchair into an obstacle-mounting wheelchair, allowing an occupant to glide over obstacles such as sidewalk curbs. After removal of the large rear wheels and smaller front wheels of a conventional wheelchair, a pair of triangular belted support members are fitted to the frame of the wheelchair such that the frame hangs in a pendulum arrangement from the support members. The support members each have a rubber belt extending around their periphery on bearing mounts, and the wheelchair is propelled by an occupant grasping a portion of the two belts at the front of the support members and moving the belts downward. A pair of guide members are attached through spring-biased axles to a forward position on the wheelchair frame or a forward position on the support members. The guide members extend in an upward forward orientation, and rotate against bias when the front of the wheelchair encounters a curb or other obstacle. As they attempt to return to their unbiased position, the guide members lift the front part of the wheelchair, allowing the wheelchair to glide over obstacles with little reduction in forward speed.

Filed: 2000-03-29
Granted: 2012-01-24
Abstract: A limited-use mobile telephone operable within at least one mobile telephone network within a region of said mobile telephone's intended use. All direct charges for use of the telephone are prepaid, and the telephone is characterized by a set of limiting events. In one embodiment, the telephone includes a sole power source internal to the telephone and not readily replaceable or rechargeable by an end user. In that embodiment, the set of limiting events includes the end of the elapsed life of the power source, the end of use covered by prepaid charges, and a preset point in time. The telephone is of no operational use to an end user after the occurrence of the earliest implemented limiting event. Prepaid direct charges may be based on completion of a preset number of calls or expiration of a preset amount of air time. The telephone may be further limited to outgoing calls, a limited set of telephone numbers which may be dialed from the telephone such as an emergency number for the region of intended use or lcoal numbers only. To prevent inadvertent activation, one embodiment of the telephone includes only a single user input device for dialing, thereby preventing mis-dialed numbers. The telephone may be adapted to allow a purchaser to select the preset number(s). A guard is provided in one embodiment for preventing inadvertent activation of the telephone. In an alternative embodiment, the telephone is adapted to receive requests for telephone from a system at a dialed number, determine the characteristic, and respond to the system at the dialed number with a data stream indicating the characteristic. An embodiment of the telephone capable of receiving requests for, determining, and responding with the telephone's geolocation is described. Another alternative embodiment is disclosed wherein use of the telephone may be refreshed after the occurrence of a limiting event.

Patent CA-2325116-C (CA)
Inventor: JELEA FLORIN
IPC: H04L25/06

Granted: 2007-01-09
Abstract: The present disclosure discloses a method and apparatus for slicing data, or "squaring up" a signal such as the output of a wireless receiver demodulator for proper interface with conventional digital logic circuits. The method involves the receiving of an input signal, the generation of a reference level, the comparison of the input signal to the reference level, and the measurement and storage of the reference level.  The reference level is generated by applying the input signal to a filter, which has been previously set to an initial condition. The reference level is measured at a predetermined point in a receive data frame, and is maintained at the desired level throughout the remainder of the frame. After a frame has been received, the reference level is stored if the frame data output from the data slicer contained no errors. For multi-channel receivers, in which a different data slicer reference level may be optimal for each channel, a separate filter initial condition can be stored for each channel, and the reference level is set to the stored initial condition corresponding to the current channel prior to receiving data on the current channel.

Granted: 2007-08-14
Abstract: A coordinated multi axis hinge arrangement provides a snap action between stable open and closed states. When the hinges operate between the stable open and closed states across a dead center position, resilient forces imparted by torsionally rigid connecting elements (33.1, 33.2) of the hinge to adjacent hinge parts such as body and lid elements are transferred by coupling or transmitting areas (45.1, 45.2) adjacent the bending regions (34.1 - 34.4) or film hinges to remote resilient deformation energy storage areas (40.1 - 40.3). As the inge passes a dead center position, this energy is in turn supplied and returned to the rigid connecting elements to impart snap action to the closure. The closure may be cast as a single piece of plastic material and may be cast in the open position.

Title: Method and communications system for processing state information in a management network having a number of management levels
Inventor: HIRSCH LUCIAN
IPC: H04W92/14
Filed: 1999-05-03
Granted: 2009-04-28
Abstract: According to the invention, state information is transmitted between an agent (AG) of a management level (B, C) and at least one manager (MA1, MA2) of a next higher management level (A, B). A request message (staAS) is sent by the manager (MA1, MA2) to the agent (AG) for executing information matching. State information regarding deviations from a normal state are checked by the agent (AG) and changes in state information are sent to the manager (MA1, MA2) in one or several successive messages (staCN). Information matching is conducted only when changes in state information exist so that deviations from normal state are informed to the manager.  Consequently, all state information regardless of whether said information has changed or not is not automatically transmitted to the manager. This results in reduced information flow between the agent and the manager and represents a considerable gain for the manager especially in the case of a plurality of managed objects.
